Answer:
m∠2 = 135°.
Step-by-step explanation:
∠1 and ∠2 are supplementary angles, meaning that they both sum up to 180°. Therefore:
m∠2 = 180 - m∠1
m∠2 = 180 - 45
m∠2 = 135°.
Point M divides line segment AB, in the direction from A to B, in a ratio of 5 to 3. What value on the number line would indicate the location of point M? A = --6, B = 3
Answer:
The coordinates of point M is -0.375.
Step-by-step explanation:
Given that point A = -6 and point B = 3
Point M divides line segment AB in the direction from A to B in the ratio of 5 to 3 we have;
Length from A to M = 5/(5 + 3) × Length of segment AB
Given that length of segment AB = 3 - (-6) = 3 + 6 = 9, we have;
Length from A to M = 5/8 × 9 = 45/8 = [tex]5\frac{5}{8}[/tex] = 5.625
Therefore, the coordinates of M = -6 + 5.625 = -0.375 = -3/8
The coordinates of point M = -0.375.
if x= 3y-2/4, what is the value of y in terms of x?
Answer:
[tex]x = \frac{3y - 2}{4} [/tex]
Multiply through by 4
We have
[tex]3y - 2 = 4x[/tex]
Send 2 to the right side of the expression
That's
[tex]3y = 4x + 2[/tex]
Divide both sides by 3
That's
[tex] \frac{3y}{3} = \frac{4x + 2}{3} [/tex]
We have the final answer as
[tex] y = \frac{4x + 2}{3} [/tex]
Hope this helps you
Answer:
[tex]y = \frac{4x + 2}{3} [/tex]

[tex]x = \frac{3y - 2}{4} [/tex](Given)
Multiply by 4 on both sides:
[tex]4 \times x = \frac{3y - 2}{4} \times 4[/tex]
Calculate
[tex]4x = 3y - 2[/tex]
Add 2 on both sides
[tex]4x + 2 = 3y - 2 + 2[/tex]
[tex]4x + 2 = 3y[/tex]
[tex]3y = 4x + 2[/tex]
Divide both sides of the equation by 3
[tex] \frac{3y}{3} = \frac{4x + 2}{3} [/tex]
Calculate
[tex]y = \frac{4x + 2}{3} [/tex]
Hope this helps...

Answer:
90º clockwise rotation
Step-by-step explanation:
The rotation is a 270º counterclockwise rotation, since 270º rotation is
(x, y) → (y, -x)
F(1, 3) → (3, -1)
270º counterclockwise rotation is the same as a 90º clockwise rotation, so the answer is 90º clockwise rotation.
The length of the smaller rectangle at the right is 1 inch less than twice its width. Both the dimensions of the larger rectangle are 2 inches longer than the smaller rectangle. The area of the shaded region is 86 square inches. What is the area of the larger rectangle? PLEASE its important
Answer: 464 square inches is the area of the larger rectangle.
Step-by-step explanation: Assuming that the shaded area is the part of the large rectangle outside the small rectangle, you can set up dimensions from the information given.
The small rectangle's Area = w (2w -1) which is 2w² -w
The large rectangle's Area = (w + 2)(2w + 1) which is 2w² + 5w +2
Now figure out the equation for the "shaded area" (probably outside the small rectangle) 2w² + 5w +2 -(2w² -w) = 86 (The 2w² terms cancel)
6w + 2 = 86, so 6w = 84, w=14
Substitute 14 for w in the dimensions of the large rectangle: (w + 2)(2w + 1)
(14+2)(2[14] + 1) = Area
16 × 29 = 464

2. Write the following decimals as common fractions in their simplest forms
a) 0,8
b) 0,03
Answer:
4/5, 3/100
Step-by-step explanation
Let's look at 0.8 first.
0.8 is 8/10, but there's some more.
Let's divide 8 / 2. It is 4.
and, 10 / 2 is 5.
so, 0.8's simplest form is 4/5.
and, 0.03's simmplest fraction is easy.
It is 3/100, cuz 3 is a prime number and 3's integer is only 1 and 3.

Suppose a company did $2,000,000 in annual maintenance in 2013 and expects 80% of those to renew for 2014. Suppose that product sales for 2013 were 2,000,000(which include free maintenance in 2013) and 75% of those were expected to pay annual maintenance of 10% of the purchase price in 2014. What will be the annual maintenance collected in 2014?
Please help me. I'll mark the best answer brainiest- just HALPPP
Answer:
$1,750,000
Step-by-step explanation:
The company did $2,000,000 in annual maintenance in 2013 and expects 80% of those to renew for 2014.
That will result in annual maintenance of:
(80 / 100) * 2000000 = $1,600,000
The product sales for 2013 were 2,000,000 (which include free maintenance in 2013) and 75% of those were expected to pay annual maintenance of 10% of the purchase price in 2014.
That will result in annual maintenance of:
(75 / 100) * (10 / 100) * 2000000 = $150,000
Therefore, the total annual maintenance will be:
$1600000 + $150000 = $1,750,000
Un ciclista debe realizar una ruta a través de una carretera para ir desde una ciudad A hasta una ciudad B en varios tramos. El primer tramo mide dos tercios del tercer tramo, el segundo tramo es dos veces mayor que el tercer tramo y el cuarto tramo tiene la medida del primero más el segundo. Si el último tramo es de 80 km, ¿cuál será la distancia total recorrida de la ciudad A hasta la ciudad B?
Respuesta:
190 km
Explicación paso a paso:
Lo primero es hacer las equivalencias, sea a el primer tramo, b el segundo tramo, c el tercer tramo y el ultimo tramo, el cuarto sería d, entonces:
a = 2/3*c
b = 2*c
d = a + b
Ahora bien sabemos que d = 80, reemplazamos y nos queda:
80 = a + b
tanto a cómo b están en función del tercer tramo es decir de c, reemplazamos:
80 = 2/3*c + 2*c
80 = 8/3*c
c = 80*3/8
c = 30
ahora calculamos tanto a como b:
a = 2/3*30 = 20
b = 2*30 = 60
Ahora, el recorrido total es la suma de todos los tramos:
Total = a + b + c + d
Total = 20 + 60 + 30 + 80 = 190
Quiere decir que la distancia entre la ciudad A y la cuidad B es de 190 km

Suppose you were deciding on a ticket price for a fundraiser dinner. There may be a temptation to continue to raise the ticket sales to increase the amount of money raised. Sounds like an okay idea to raise the most money possible for a charity. You may have heard of a guest speaker at a fundraising dinner where people are charged $100 a plate or more. What do you think is a realistic price for tickets? What are the consequences of raising the price $50 or $100 to $150 a plate or $200 a plate.
Answer:
$50 per ticket.
Step-by-step explanation:
Although it is tempting to keep raising the price for a higher profit, if you raise the price by too much, people will stop buying tickets and you will not gain as much money as you could have gotten with, say, $50 per plate.
The more you raise the price, the less tickets you can sell.
Hope this helps!
In your own words, tell how geometric sequences are related to exponential functions. Share your answer with the rest of the group.
Answer:
Geometric sequences are the long way to show an exponential function. The initial amount in both exponential functions and geometric sequences do the same thing, which is state the initial value and the value by which it is multiplied. What is called the common ratio in a geometric sequence is basically the second part of what the initial amount does in an exponential function. The nth term in a geometric sequence is the same as the power in an exponential function, that is to say that it shows how many times the sequence is repeated.
Step-by-step explanation:
In a certain company, all employees are either beta employees or standard employees. In this company, 25% of the beta employees and 17% of the standard employees participate in the voluntary equity program. Let S be the number of standard employees. If there are 600 employees total, what is the value of S?
In addition to the question, the following conditions must be met:
(1) M > 100
(2) more than 130 employees participate in the voluntary equity program
Answer:
Value of A is 200
Step-by-step explanation:
In this scenario when we divide 100 by the percentage of each employee category we will get a proportion that the number of employees must obey.
This is illustrated below:
For Beta employees 100/25= 4
So the number of employees that are Beta must be divisible by 4
For Standard employees 100/17 = 5.882
Since fractions of employees cannot be obtained, in this case the number of employees must be a multiple of 100
Total employees are 600
The various combinations are:
1. Beta employees 500 and Standard employees 100
Survey participants= (0.25 * 500) + (0.17 * 100) = 142
Number of participants is okay as it is >130 but does not satisfy Standard employees being >100
2. Beta employees are 300 and Standard employees are 300
Survey participants = (0.25 * 300) + (0.17 * 300) = 126
This does not satisfy condition of survey participants >130
3. Beta employees 400 and Standard employees 200
Survey participants = (0.25 * 400) + (0.17 * 200) = 134
This satisfies conditions of >130 survey participants and Standard employees >100
So correct value of S is 200

Riley has a farm on a rectangular piece of land that is 200200200 meters wide. This area is divided into two parts: A square area where she grows avocados (whose side is the same as the length of the farm), and the remaining area where she lives.
Every week, Riley spends \$3$3dollar sign, 3 per square meter on the area where she lives, and earns \$7$7dollar sign, 7 per square meter from the area where she grows avocados. That way, she manages to save some money every week.
Write an inequality that models the situation. Use lll to represent the length of Riley's farm.
Answer:
The inequality that models the situation for her to have money to save is
7L² > 3(200L - L²)
On simplifying and solving,
L > 60 meters
Step-by-step explanation:
The length of her farm = L meters
The farm where she grows avocados is of square dimension
Area of the farm = L × L = L²
The piece of land is 200 m wide.
Total area of the piece of land = 200 × L = (200L) m²
If the area of her farm = L²
Area of the side where she lives will be
(Total area of the land) - (Area of the farm)
= (200L - L²)
= L(200 - L)
Every week, Riley spends $3 per square meter on the area where she lives, and earns $7 per square meter from the area where she grows avocados.
Total amount she earns from the side she grows the avocados = 7 × L² = 7L²
Total amount she spends on the side where she lives = 3 × (200L - L²) = 3(200L - L²)
For her to save money, the amount she earns must be greater than the amount she spends, hence the inequality had to be
(Amount she earns) > (Amount she spends)
7L² > 3(200L - L²)
To simplify,
7L² > 3L(200 - L)
Since L is always positive, we can divide both sides by L
7L > 3(200 - L)
7L > 600 - 3L
10L > 600
L > 60 meters

30 Points!! Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?
Answer:
Its a postive number
Step-by-step explanation:
If you look it says she is at sea leveal wicth is 0 and she is going up 12.3 feet so its postive.
The change in elevation from the bottom of the Ferris wheel to the top is 21.9 feet, which is a positive number.
What is subtraction?The process of subtracting one number from another is known as subtraction.
Given that, the lowest point of the Ferris wheel is -9.6 feet, and the highest point is 12.3.
The change in elevation from the bottom of the Ferris wheel to the top of the Ferris wheel is,
12.3 - (-9.6)
=12.3 + 9.6
= 21.9
Hence, the change in elevation from the bottom of the Ferris wheel to the top is 21.9 feet, which is a positive number.
