Select all the statements about the situation that are true. Elena makes more money for making 10 calls than Diego makes for washing 10 windows. Diego makes more money for washing each window than Elena makes for making each call. Elena makes the same amount of money for 20 calls as Diego makes for 18 windows. Diego needs to wash 35 windows to make as much money as Elena makes for 40 calls. The equation y = 910x, where y is number of dollars and x is number of windows, represents Diego's situation. The equation y = x, where y is number of dollars and x is number of calls, represents Elena's situation.

Answers

Answer:

B, C, E

Step-by-step explanation:

Elena’s aunt pays her $1 for each call she makes to let people know about her aunt’s new business. The table shows how much money Diego receives for washing windows for his neighbors.

Select all the statements about the situation that are true.

A. Elena makes more money for making 10 calls than Diego makes for washing 10 windows.

Elena:

$1 = 1 call

$10 = 10 calls

Diego:

27 windows = $30

10 windows = $x

Cross product

27*x = 30*10

27x = 300

x = 300/27

x = $11.11

Statement A not true

B. Diego makes more money for washing each window than Elena makes for making each call.

Diego:

10 windows = $11.11

Each window = $11.11/10

= $1.11

Statement B is true

C. Elena makes the same amount of money for 20 calls as Diego makes for 18 windows

Elena:

20 calls = $20

Diego:

18 windows = 18 × $1.11

= $19.98

Approximately $20 to the nearest whole dollar

Statement C is true

D. Diego needs to wash 35 windows to make as much money as Elena makes for 40 calls.

Diego

35 × $1.11 = $38.85

Approximately $39

Elena:

40 calls = $40

Statement D is not true

E. The equation y = x, where y is the number of dollars and x is the number of calls, represents Elena’s situation.

Statement E is true

Which choice is equivalent to the expression below?
5^9.969

​

Answers

Answer:

A.

Step-by-step explanation:

got it right on test

The provided expression is equivalent to the expression mentioned in option (A), and option (A) is correct.

What is an integer exponent?

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

We have:

[tex]= 5^{9.969}[/tex]

We can write it as:

[tex]= 5^{\dfrac{9969}{1000}}[/tex]

or

[tex]= 5^{\dfrac{9000+900+60+9}{1000}}[/tex]

[tex]= 5^{{9}} \ 5^{\dfrac{9}{10}} \ 5^{\dfrac{6}{100}} \ 5^{\dfrac{9}{1000}}[/tex]

Thus, the provided expression is equivalent to the expression mentioned in option (A), and option (A) is correct.

of Tank A, which measures 80 cm by 30 cm by 50 cm, is filled with water
and of Tank is nilled with water. The ratio of the volume of water in
Tank A to that in Tank Bis 5. 2. How much more water is needed to up
Tarik ?​

Answers

Answer:

72L

Step-by-step explanation:

I'm assuming Tank A and Tank B have the same volume. The question has many typos and is a bit hard to understand

Tank A Volume

V = l × w × h

= 80 × 30 × 50

= 120,000cm²

Tank A Capacity = 120,000ml

=120L

The Question states that Tank A is filled to capacity which means Tank A currently holds 120L of water

Tank A:Tank B = 5:2 = 120:x

120 ÷ 5 = 24L

24 × 7 = 168

168 × [tex]\frac{2}{7}[/tex] = 48

This means Tank B currently holds 48L of water

120 - 48 = 72L

∴72 more litres of water is needed to fill Tank B

The graph shows the distance a bicyclist traveled from a starting point in 10-second increments. Which of these is closest to the average speed of the bicyclist during 30 seconds of motion?
A. 0.3m/s
B. 3m/s
C. 10m/s
D. 30 m/s
PLEASE HELP QUICK!​

Answers

Answer: 3m/s

Step-by-step explanation:

the formula for speed is distance divided by time, the question tells us the time is referring to the first 30 seconds, so just divide the distance by time (the answers you’d get are 3, 3, 1) so 3 m/s is closest to the average speed

The average speed of the bicyclist during 30 seconds of motion is mathematically given as

v'=3m/s

What is the average speed of the bicyclist during 30 seconds of motion?

Question Parameter(s):

During 30 seconds of motion

Generally, the equation for the  speed is mathematically given as

v=d/t

Therefore

v'=(30/10+60/20+30/30)3

v'=3m/s

In conclusion, Average speed

t + s = 180                   They are supplementary angles

158 + s = 180               Subtract 158 from both sides

s = 180 - 158

s = 22

A silo has a radius of 10 meters, like the one shown, and is filled from top to bottom with rice. If rice sells for $75 a cubic meter, what is the total value of rice in this silo?

Answers

Answer:

$1500

Step-by-step explanation:

Since the radius of the silo is 10 meters, then the total length of the silo is 20 meters. So now we multiply 75 by 20

75 x 20 = 1500

So the value of the rice in the silo is $1500
