Bentley had $40 in birthday money in her piggy bank. She spent $10 on new flip-flops, then got $20 for her allowance and did not spend any of that money for 1 week. Finally, she spent $15 on new sunglasses.
Which part of the scenario is best represented by a linear increasing interval?
A. Bentley has $40 in her piggy bank.
B. Bentley spent $10 on new flip flops.
C. Bentley got $20 for her allowance.
D. Bentley spent $15 on sunglasses.
Answer:
C. Bentley got $20 for her allowance.
Step-by-step explanation:
If Bentley was given $40 at first, then spent $10, we plot a line on the graph that decreases and then she receives $20. $20 is bigger than $10, therefore this is the scenario best represented by a linear increasing interval.
I hope this makes sense!! ^-^
Brad expected that a jar will hold 252 grams of powder, but the label shows that it contains 240 grams of powder. Calculate the percent error
Answer:
4.76%
Step-by-step explanation:
A jar will hold 252 grams of powder
The label shows that its contains 240 grams
Therefore the percent error can be calculated as follows
= 240-252/252 × 100
= -12/252 × 100
= 0.0476 × 100
= 4.76%
Hence the percent error is 4.76%

3a. Angles q,r, and u are 105 degrees.
b. Angles p,s, and t are 75 degrees.
Step-by-step explanation:
Vertical angles, or angles that are across from each other, are congruent, meaning they are the same angle. When you shrink it, its angles are still the same.

20
−
2
y
Answer:
r = 10
y = 11
Step-by-step explanation:
4y = 40 + 4
4(r + 1) = 40 + 4
4(r) + 4(1) = 40 + 4
4r + 4 = 40 + 4
4r + 4 = 44
4r + 4 - 4 = 44 - 4
4r = 40
4r ÷ 4 = 40 ÷ 4
r = 10
-----------------------------------------
y = r + 1
y = (10) + 1
y = 11
-----------------------------------------
4y = 40 + 4
4(11) = 40 + 4
4(11) = 44
44 = 44
Peter determined the area, in square miles, of a piece of land using his calculator. The result of his calculation is displayed on his calculator in scientific notation as 7.4e – 4.
Which statement is true of the area of the piece of land?
Answer:
The true statement of the area of the piece of land is;
(C) It is between 0.0007 and 0.007 square mile
Step-by-step explanation:
Using scientific notation, we have the value of a measurement presented as follows;
c × 10ⁿ = ce±n
Where;
c = The coefficient number, less than 10
en = 1 × 10⁺ⁿ
e-n = 1 × 10⁻ⁿ
Therefore, the given number, 7.4 e - 4, can be expressed as follows;
7.4 e - 4 = 7.4 × 10⁻⁴ = 0.00074
0.00074 ≈ 0.0007 and we have;
0.0007 < 0.00074 < 0.007
The correct option is therefore that it is between 0.0007 and 0.007 square mile
The statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074
The standard form for writing scientific notation is given as A * 10^n
Given the result of his calculation displayed on his calculator in scientific notation as 7.4e^-4.Writing this as a standard value will give:
7.4e^-4 = 0.00074 (Note that the decimal point was shifted back in four placsHence the statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074

Answer:
see attachments
Step-by-step explanation:
The side lengths are found using the distance formula.
d = √((x2-x1)^2 +(y2-y1)^2)
For example, the length of RS in the first triangle is ...
d = √((4-(-1))^2 +(4-(-3))^2) = √(25 +49) = √74 ≈ 8.602
This same computation is used for all of the sides of the triangles. When the same tedious computation is repeated over and over, I like to use a spreadsheet to do it. In the attached spreadsheet the two points used are the one on the same line as the distance, and the one on the line below. Side lengths are shown in the attachment to 3 decimal places.
__
In order to classify the triangle as acute, right, or obtuse, we can compare the side lengths to those of a right triangle. For the purposes of computation in a spreadsheet, it is convenient to compute the middle length side of a right triangle that has the same longest and shortest sides as the triangle we have.
If the computed side is longer than the actual middle side, then the triangle we have is obtuse. If it is shorter, the triangle we have is acute. If it is exactly the same, then the triangle we have is a right triangle.
In every case here, the computed middle side is shorter than the actual middle-length side, so all of the triangles are acute triangles. (The one of problem 39 is isosceles, since two sides are the same length. The others are scalene.)

The triangles are graphed in the second attachment.

The song lasts 3 minutes and 27 seconds. If Rasmus' beloved has to get home before the song is over, and rides a bike at an average speed of 15 km / h, how far away must her work be from their home?
Set up an equation that describes the problem where x is the distance between home and work.
Answer:
Kindly check explanation
Step-by-step explanation:
From the question :
Duration, time, t = 3 minutes, 27 seconds = (3 * 60) + 27 = 207 seconds
Average speed = 15 km/h = (15*1000) /3600 = 4.16666 m/s
Let distance = x
Recall:
Speed = distance / time
Distance = speed * time
x ≤ (speed * time)
x ≤ (4.16666 * 207)
x ≤ 862.5 m
x ≤ (862.5 / 1000) km
x ≤ 0.862.5 km

Shifted by 6 units left on the x-axis.
Step-by-step explanation:
Given function is,
f(x) = 5ˣ + 1
After transformation, this function becomes g(x) = [tex]5^{(x+6)}+1[/tex]
Here, g(x) = f(x + 6)
By the rule of transformation,
Function 'f' has been shifted by 6 units left on the x-axis to form a new function 'g'.

I will do it in a way that can solve all these kinds of problem.
Of course, you can just substitute every possible answer in and see which one has the highest y value.
BUT I'm going to do this question by completing the square.
First organize the equation by decreasing degrees.
y=-16t^2+32t
Now factor out a -16 to make the x variable have no coefficient.
y=-16(t^2-2t)
Now complete the square.
y=-16(t-1)^2+16
By this if you graph it its the parent graph y=x^2, its a reflection over x axis by the negative sign at the beginning, then a vertical stretch by 16, and then go to the right by 1 then up by 16. This meant that the vertex is (0,0) go right 1 and up 16.
The vertex or the highest point of the graph is point (1,16) This also meant that its after 1 second at 16 feet height. The answer is B.
Alguien me pude decir una adivinanza o historia q la solución sea una ecuación de segundo grado completa????
Answer:
Una ecuación de segundo grado completa es algo como:
y = a*x^2 + b*x + c
Un problema tipico que usa ecuaciones de este tipo es algo que nos haga multiplicar dos términos como h*(x + k) y n*(x + j)
Donde h, k, n, y j son números reales.
Entonces planteemos el siguiente caso.
"Juan tiene una tabla rectangular, de tal forma que su largo es (x + 3cm), y el ancho es igual a dos veces su largo, si sabemos que el área de esta tabla es 95 cm^2 ¿cuál es el valor de x?"
Acá hay que recordar que para un rectángulo de largo L y ancho W, el área es:
A = L*W
En este caso tendremos:
L = (x + 3cm)
Y el ancho es dos veces eso, entonces:
W = 2*(x + 3cm)
Entonces el area de esta tabla se escribirá como:
A = (x + 3cm)*2*(x + 3cm)
Ahora solo tenemos que expandir eso:
A = 2*x^2 + 12cm*x + 18cm^2
Ahora sabemos que el area de esta tabla es 95cm^2
Entonces:
95cm^2 = 2*x^2 + 12cm*x + 18cm^2
0 = 2*x^2 + 12cm*x + (18cm^2 - 95cm^2)
0 = 2*x^2 + 12cm*x - 77 cm^2
Esta es una ecuación de segundo grado completa, la cual deberiamos resolver para encontrar el valor de x como se nos pide en el problema.
