Tom fed the dog 3 times as many times as her sister last week. His sister walked the dog 9 times. Max said he could multiply 4 times 9 to find out how many more times he walked the Dog than his sister. Is Tom correct?

Answers

Answer:

No

Step-by-step explanation:

The calculation that Tom is trying to do would be to calculate how many times he walked the dog if he had walked the dog 4 times as many times as his sister, who in this scenario walked the dog a total of 9 times. Since, in this scenario there is no mention of how many times Tom walked the dog then this calculation cannot be made and I would say that Tom is not correct.

can someone plz help i need to graph it and identify the x-intercept

Answers

Answer:

(-7/2,0) is the x intercept

Step-by-step explanation:

1. y+3 = -6/7x

2.  -3              -3 ....subtract 3 from both sides to isolate the variable y

y= =-6/7x -3 ....is your new equation

You graph it by putting your point on negative three and then counting 6 units down and 7 units right.

For the x intercept you set y to 0 and solve for x

0= -6/7x -3

+3               +3 ...to both sides

3= -6/7x .....divide both sides by -6/7

-7/2=x

Greatest common factor of 25,50,75

Answers

Answer:

gcd (50; 75) = 25 = 5^2:

Step-by-step explanation:

hope it help

The greatest common factor of 25, 50 and 75 is 5*5, which is equal to 25.

We are given that;

The three numbers = 25, 50, 75

Now,

The greatest common factor (GCF) of two or more numbers is the largest positive integer that divides evenly into all the numbers with zero remainder.

To find the GCF of 25, 50 and 75, we can use the prime factorization method. This involves writing each number as a product of its prime factors and then finding the common factors among them.

The prime factorization of 25 is 5*5

The prime factorization of 50 is 2 x 5*5.

The prime factorization of 75 is 3 x 5*5.

The common factors of 25, 50 and 75 are 1 and 5*5.

Therefore, by factorization the answer will be 25.

Rob is saving money for a down payment on a house. He opens a savings account at his local bank and deposits $1000. He models his savings plan with the equation y=400x+1000
based on his current income and monthly savings rate. What is the meaning of the y-intercept in the equation?

Answers

Answer:

x=-5/2

Step-by-step explanation

y=0

0=400x=1000 divide both sides

x=-5/2

Answer:

The Answer is D: Starting amount in his savings account

Step-by-step explanation:

The y-intercept represents the starting amount in his savings account.

x = 0 for the y-intercept.

y = 400x + 1000

y = 400(0) + 1000

y = 1000

Day 17, they will have the same amount of money.


$92 - ($5 • 17) = 7

$41 - ($2 • 17) = 7

Let 17 represent the amount of days they both spent money, AND the day they ended up with the same amount of money. No other day before 17, they would’ve had the same amount of money. You can figure this out by plugging a different number in for 17, and seeing the answer will not be the same for both equations

Given constant temperature, P1 = 25 psia, P2 = 40 psia, and V1 = 30 cu in, what is V2 in cubic inches? Select one: a. 15 b. 17.5 c. 18.75 d. 33.33

Answers

Answer:

V2 = 18.75 cu in

Step-by-step explanation:

Given that:

Given constant temperature :

P1 = 25 psia, P2 = 40 psia, and V1 = 30 cu in,

Calculate v2

Using the relation :

Since Temperature T is constant ;

P1V1 = P2V2

25 * 30 = 40 * V2

750 = 40V2

V2 = 750 / 40

V2 = 18.75 cu in

Step-by-step explanation:

His number is x.

"If you subtract 19 from my number"

x - 19

"and multiply the difference by - 7"

-7(x - 19)

"the result is  -140."

-7(x - 19) = -140

Measure of angle T is 67.5 and measure of angle V is 22.5

Step-by-step explanation:

Solve for x

All the angles in a triangle equal 180

So,

3x + x +90 is 180.

Subtract 90 from both sides

3x+x = 90

Add like terms

4x = 90

Divide by 4 to solve for x

x = 22.5

Now substitute 22.5 in for 3x and x

Measure of angle T is 3(22.5) = 67.5 and measure of angle V is 22.5
