Answer:
A = 16.5
T = 33
B = 10.5
Step-by-step explanation:
T = 2A
B = A-6
T + B + A = 60
(2A) + (A-6) + A = 60
4A - 6 = 60
4A = 66
A = 16.5
T = (16.5)*2 = 33
B = 10.5
A triangle has congruent angles. Two of the angles measure 68° and 56°. How many degrees are in the third angle?
A. 68
B. 18
C. 56
D. not enough information
Answer:
C. 56
Step-by-step explanation:
So if the total amount of degrees in a triangle is 180
(degrees = 180(n-2), d = 180(3-2), d = 180), then 180 = 68 + 56 + x
solve the equation for x
180 = 68 + 56 + x
180 - 68 - 56 = x
x = 56

Answer:
a = 30°
b = 11°
Step-by-step explanation:
JK = 360 - 110 - 130 - 54 = 66°
Inscribed angles = 1/2 their arc
∠K = 1/2(130 + 54) = 92°
∠J = 1/2(110 + 130) = 120°
∠M = 1/2(66 + 110) = 88°
8b = 88°
b = 11°
∠L = 1/2(54 + 66) = 60°
2a = 60°
a = 30°
The point (-3, 2) lines on a circle whose equation is (x + 3)2 + ( + 1)2 = r2. Which of
the following must be the radius of the circle?
Answer:
3 units
Step-by-step explanation:
Equation of the circle is:
[tex] (x+3)^2 +(y+1)^2=r^2 [/tex]
[tex] \therefore [x-(-3)] ^2 +[(y-(-1)] ^2=r^2 [/tex]
Equating it with
[tex] (x-h)^2 +(y-k)^2=r^2 [/tex]
We find: h = - 3 & k = - 1
Center of the circle (C) = (-3, - 1)
Since, the point (-3, 2) lies on the circle, therefore radius of the circle wii be equal to the distance between the center of the circle (-3, - 1) and the point (-3, 2) which is on the circle.
Therefore,
[tex] r = \sqrt{[-3-(-3)]^2 +[2-(-1)]^2} [/tex]
[tex] r = \sqrt{[-3+3]^2 +[2+1]^2} [/tex]
[tex] r = \sqrt{[0]^2 +[3]^2} [/tex]
[tex] r = \sqrt{0 +9} [/tex]
[tex] r = \sqrt{9} [/tex]
[tex] r = 3\: units [/tex]
find the distance between M (-1,-1 ) and H (1,-2)
Answer:
sqrt(5)

Penelope decides to reduce her math tutoring to half the amount of time she has been tutoring each month. After making this change, what will be her total amount of monthly income?
Answer: $300 per month (assumed)
Step-by-step explanation:
As figures are lacking in this question, I will use assumed figures and you can use it as a reference.
Assume Penelope had been tutoring for 60 hours a month and her hourly rate was $10 originally.
If she reduces this time to half, the amount of hours she begins to tutor is:
= 60 hours / 2
= 30 hours
At a rate of $10 an hour, her monthly income becomes:
= 10 * 30
= $300 per month

Step-by-step explanation:
A campus courtyard is in the shape of a rectangle and consists of grass surrounded by a concrete path. The dimensions of the
entire courtyard are 25 ft. by 20 ft. The concrete path is 3 feet wide all the way around. The school decides to replace the
grassy area. A landscaping company charges $.20 per square foot for grass and $.60 per square foot to install it.
Approximately how much would the school save if the math club volunteered to install it instead of having the landscape
company install it?
Answer:
I think they'd be saving approximately $300

Answer:

Step-by-step explanation:
The quadratic formula is
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$.[/tex]
where a is the coefficient of x squared, b is the coefficient of x, and c is a regular number.
Here, we have
a = 1
b = 7
c = 16
Plugging in values, we have
[tex]\frac{-7 +\sqrt{49 - 4(1)(16)}}{2(1)}[/tex]
and
[tex]\frac{-7 -\sqrt{49 - 4(1)(16)}}{2(1)}[/tex]
The first equation solves to an i term, so there is no way that there is an answer.
The second equation is also an i term, meaning there are no solutions to this equation
You have a bag of gummy worms. 12 are green, 3 are blue, 6 are red, and 2 are orange. What is the probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm?
The probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm:
What is probability?Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.
Probability of Event = Favorable Outcomes/Total Outcomes = X/n
The probability of pulling a red worm from the bag is 6/(12+3+6+2) = 6/23.
After eating the red worm, there are 11 green worms left in the bag, so the probability of pulling a green worm is 12/(12+3+2) = 12/17.
To find the probability of both events occurring (pulling a red worm and then a green worm), we need to multiply their probabilities:
P(red and green) = P(red) × P(green)
P(red and green) = (6/23) × (12/17)
P(red and green) = 72/391
Therefore, the probability of reaching into the bag and pulling a red worm, eating it, and then pulling a green worm is 72/391.

Student A starts with $100 in the bank and makes $5 a day. Student B starts with $50 and makes $7 a day. Assuming the students save their money, when will they have the same amount of money ?
Answer:
No. They will not have the same amount of money.
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 3.875/100
r = 0.03875 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 10,000.00(1 + 0.03875/12)(12)(7.5)
A = 10,000.00(1 + 0.003229167)(90)
A = $13,366.37
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $10,000.00 at a rate of 3.875% per year compounded 12 times per year over 7.5 years is $13,366.37. Therefore, they cannnot save the same amount.

Maria is in charge of making punch for the party she adds two quarts of water to 1 quart of orange juice and 2 quarts of mango juice then she adds one quart of crushed strawberry juice and 2 quarts of pineapple juice to the mixture how many quarts of punch does Maria make?
Answer:
8 quarts
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Water = 2 quarts
Orange Juice = 1quarts
Mango Juice = 2 quarts
Strawberry juice = 1 quart
Pineapple Juice = 2 quarts
So, Total mixture = Sum of all ingredients in quarts
= 2 + 1 + 2 + 1 + 2 = 8 quarts
Hence, Maria makes 8 quarts of punch.

Answer:
Aonnalin, great name :) answer as below
Step-by-step explanation:
They tell us to use slope-intercept form. This is something you will just have to remember y = mx+b
It is confusing b/c there is the other one, the point-slope formula too. but just remember both and know that the point-slope one is to get to the slope-intercept one. y-y1 = m(x-x1)
m= slope
m = (y2-y1) / (x2-x1)
P1= (0,7) in the form (x1,y1)
P2 =(8,-2) in the form (x2,y2)
m = -2-7 / 8-0
m = -9 / 8
now that we have the slope, just use either point with the point-slope
y-7 = (-9/8)(x-0)
y-7 = -9x/8
y = -9x/8 + 7
y = [tex]\frac{-9}{8}[/tex] X + 7
slope-intercept form :)
Stacy made 3 of her car payments late and was fined 3 late fees. The total change to her savings from late fees was - $24. How much was each late fee?
Answer:
$8
Step-by-step explanation:
I got my answer of $8 because I knew that the total amount of money she was charged for late fees was $24, and she was charged for 3 late fees. Then, I did $24 divided by 3 late fees and got $8 per late fee as my answer.
24 divided by 3 equals 8.

For which value of p and q does the following pair of linear equations have an infinite
number of solutions?
2x + 3y = 7
( p-q ) x + (p+q) y = 3 p + q -2
Answer:
[tex]p =2.5[/tex]
[tex]q = 0.5[/tex]
Step-by-step explanation:
Given
[tex]2x + 3y = 7[/tex]
[tex]( p-q ) x + (p+q) y = 3 p + q -2[/tex]
Required
Find p and q
To do this, we make direct comparison between the given expressions.
[tex]2x + 3y = 7[/tex] and [tex]( p-q ) x + (p+q) y = 3 p + q -2[/tex]
This implies that:
[tex](p - q)x = 2x[/tex]
[tex](p+q)y = 3y[/tex]
[tex]3(p + q) - 2 = 7[/tex]
So, we have:
[tex]p - q = 2[/tex] --- (1)
[tex]p+q =3[/tex] -- (2)
[tex]3(p + q) - 2 = 7[/tex] --- (3)
If [tex](1)\ and\ (2)[/tex] are true, then [tex](3)\ must[/tex] be true.
So, we only solve [tex](1)\ and\ (2)[/tex]
Add (1) and (2) to eliminate q
[tex]p+p-q+q=2+3[/tex]
[tex]2p=5[/tex]
Solve for p
[tex]p = 5/2[/tex]
[tex]p =2.5[/tex]
Substitute [tex]p =2.5[/tex] in (2)
[tex]p+q =3[/tex]
[tex]q = 3 - p[/tex]
[tex]q = 3 - 2.5[/tex]
[tex]q = 0.5[/tex]
Definitely could use some help. Would also be really appreciated if someone gave a breakdown of how they solved it. Thank you!!!

Cross multiply
200 = 24x-40

240 = 24x
Divide both sides by 24
X = 10
Solve for the equation: 3x-5 = 3(10)-5 = 30-5 = 25
What fact will help you to find the measure of angles B and C in the diagram shown?
A) An equilateral triangle has 3 congruent angles.
B)
The height of an isosceles triangle bisects the base.
C) The base angles of an isosceles triangle are congruent.
D)
The midsegment of an isosceles triangle is parallel to the base
Answer:
The Answer is C
Step-by-step explanation:
Look at B and C you can see that they have a line on each angle. Also, know that isosceles have two congruent sides. So when looking at this triangle we can infer that C is our best bet.
