Answer:

152 x 10 =1520

1520/32 = 46.06

1520 x 33 = 50,160

1520-33 = 1487

Answer:

(2x^2+7)

Step-by-step explanation:

5x^3 * 2x^2 = 10x^5

5x^3 * 7 = 35x^3

The identity equation is; 5x³(2x² - 7)

This question will be solved with the concept of factorization which involves simplifying an algebraic equation by collecting like terms and putting it in front of a bracket with the remaining terms inside that same bracket.

The algebraic equation we are working with is;

10x⁵ - 35x³

To solve this, we will list out the factors of 10 and 35 and pick the highest common factor.

factors of 10; 1, 2, 5, 10

Factors of 35; 1, 5, 7, 35

Highest common factor is 5

Also, for the x symbol, the highest common factor is xᵃ.

Thus the factor we are bringing to the front of the bracket is 5x³

To get what will remain in the bracket, we will just divide the original terms by 5x; [tex]\frac{10x^{5} }{5x^{3}} - \frac{35x^{3}}{5x^{3}}[/tex]

This gives; 2x² - 7

Thus, The identity equation is; 5x³(2x² - 7)

Answer:

P = 10w

Step-by-step explanation:

Number of point per correct spelling = 10

Number of words spelt correctly = w

Total points, p

P = (number of points per correct spelling * number of words spelt correctly)

P = 10 * w

P = 10w

Answer:

2/4 or up 2 over 4

Step-by-step explanation:

Put the points on a graph

start at the (-1,-5) and count up two

then go over 4 to the point (3,-3)

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (3, - 3)

m = [tex]\frac{-3-(-5)}{3-(-1)}[/tex] = [tex]\frac{-3+5}{3+1}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

x = 2 and y = 7

Step-by-step explanation:

We are given two equations:

1.      8x + y = 23

2. −10x  - y = −27

By adding both equations with each other we get:

(1.+2.) -2x = -4

Which can be reduced to:

(1.+2. : (-2)) x = 2

We can insert x in Equation 1. (or 2) and get:

8*2 + y = 23

16 + y = 23         [-16 on both sides]

y = 7

Resulting in x = 2 and y = 7 as a possible solution for this system.

Answer:

Step-by-step explanation:

8x + y = 23

-10x - y = -27

-2x = -4

x = 2

8(2) + y = 23

16 + y = 23

y = 7

(2, 7)

Answer:

5.   y = -x

Step-by-step explanation:

First, you need to find the slope of the line.

[tex]m = \frac{2 - (-3)}{-2 - 3} = \frac{5}{-5} = -1[/tex]

Now, using either point substitute into the point-slope form for a line:

[tex]y - y_{1} = m(x - x_{1} )[/tex]

Using (-2,2) for [tex](x_{1} , y_{1} )[/tex] we get y - 2 = -1(x +2)

y - 2 = -x - 2

y = -x

Answer 5 is the correct answer

Answer:

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

because 3 pieces

divided by 2 because there half pieces.

since m is parallel to n, this means that the two angles are alternate angles. Hence, 46°=6x-2

Calculate and you should get x = 8°

Answer:

Interquartile Range

The interquartile range of an observation variable is the difference of its upper and lower quartiles. It is a measure of how far apart the middle portion of data spreads in value.

Interquartile Range = U pper Quartile − Lower Quartile

Problem

Find the interquartile range of eruption duration in the data set faithful.

Solution

We apply the IQR function to compute the interquartile range of eruptions.

> duration = faithful$eruptions     # the eruption durations

> IQR(duration)                     # apply the IQR function

[1] 2.2915

Answer

The interquartile range of eruption duration is 2.2915 minutes.

Answer:

5 miles

Step-by-step explanation:

Hi there!

To find the rate at which Gia can run, you have to divide 4 by 32 to find how many miles she runs per min. When you do that, you get .125 Gia runs .125 miles per min. To find how many miles she runs in 40 min, you multiply .125 by 40 to get 5. This means that Gia runs 5 miles in 40 min.

Answer:

A and E

Step-by-step explanation:

The perimeter is the length of the edge of the overall shape. In this case, the edge includes the length of the curved section of both semicircles (since semicircles are the same size, we can just find the circumference for a circle with the same radius), plus four side lengths of the square.

The radius is 10 (Two squares line up exactly with the semi-circles).

Circumference: 2πr=2π10=20π

Perimeter =20π+4(10)=40+20π

A

40+20π=40+20π? YES

B

40+20π=80+20π? NO

C

40+20π=120+30π? NO

D

40+20π=300+100π? NO

E

40+20π=10+10+10π+10+10+10π? YES

Answer:

Step-by-step explanation:

The y intercept only occurs when x=0 so (0,0) is the only y intercept of those choices.
