your answer is right since your going to the right +3 and decreasing -9 units

Answer:

76.

Step-by-step explanation:

Forty "more" implies that you are adding forty to thirty-six. Making it seventy-six.

The number that is 36 more than 40 will be 76.

Algebra is the analysis of abstract symbols, while reasoning is the manipulation of all those views.

The definition of unsophistication is making something simpler to achieve or grasp while also making it a little less difficult.

Let 'x' be the number that is 36 more than 40. Then the equation is given as,

x = 36 + 40

Add the number 36 and 40, then we have

x = 36 + 40

x = 76

The number that is 36 more than 40 will be 76.

Step-by-step explanation:

since it's an isosceles triangle, DE = EF

i.e. 8x-13 = 5x+ 17

or 8x -5x = 17 +13

or 2x = 30

or X = 15

Answer:

1.50 Hours

Step-by-step explanation:

Given:

To Find:

If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Solve:

Price of stock A at 9 a.m.= $12.41

The price has been increasing at the rate of ​$0.12 each hour.

Increase in price after 3 hours = 0.12 × 3 = 0.36

Price of Stock A at noon= 12.41+0.36 =12.77

Let n be the no. of hours after which the prices of both the stocks will be same .

So, Increase in price after n hours = 0.12 n

Price of Stock A after n hours = 12.77+0.12 n

Price of stock B = 13.16

The price has been decreasing at the rate of ​$0.14 each hour.

Let n be the no. of hours

So, Increase in price after n hours = 0.14 n

Price of Stock B after n hours =13.16-0.14 n

ATQ

12.77 + 0.12n = 13.16 - 0.14n

-12.77 + 13.16 = 0.12n + 0.14n

0.39 = 0.26n

0.39/0.26 = n

n = 1.50

Hence the prices of the two stocks be the​ same after 1.50 hours after 12 pm .

The area covered if the side measures 5 meters. is 34.68 m²

The area of the shown figure is given as:

Area of the figure = area of square + area of a semicircle

Area of square = 5^2 = 25 square meters

Area of semicircle = πr²/2

Area of semicircle = (3.14)(2.5)²/2

Area of semicircle =9.6875 square meter

Area of the figure = 25 + 9.6875

Area of the figure = 34.68 square metres

Hence the area covered if the side measures 5 meters. is 34.68 m²

Answer: y = 2x -7

Step-by-step explanation:

The equation of a line is in the form y = mx + b

We know m = 2

So, y = 2x + b

we need to find b, and we can use either point given to find it:

lets use (2, -3):

-3 = 2(2) + b

-7 = b

now we know, the line's equation is y = 2x -7

Answer:

1/7 of 21 is 3.

Step-by-step explanation:

If we multiply 1/7 by 21/1, we can 21/7. 21/7 is equivalent to 3.

The third graph is the only one that is an an odd-degree polynomial with a positive lead coefficient.

An even number of total minimums/maximums of the Polynomial is classified as an odd-degree polynomial. Now, we see that only the 3rd and 4th graphs are odd-degree polynomials because they have four total minimums/maximums.

For the polynomial to have a positive leading coefficient, the line must go up in the positive direction. This means that only the 1st and 3rd graphs have a positive leading coefficient due to the fact that their right-most line is going upwards.

Thus, we can say that the third graph is the only one that is an an odd-degree polynomial with a positive lead coefficient.

Step-by-step explanation:

first, let's bring everything to the same fraction denominator, which would be 1/8 to cover all.

so, he jogs

3 2/8 miles on Monday

5 5/8 miles on Tuesday

8 0/8 miles on Wednesday

the difference from day to day is

5 5/8 - 3 2/8 = 2 3/8 (subtract the whole numbers and then also the fractional part).

to control :

5 5/8 + 2 3/8 = 7 8/8 = 8

so, he adds every day 2 3/8 miles.

that means in 2 days (from Wednesday to Friday) this will be additional 2×(2 3/8) = 4 6/8 = 4 3/4 miles.

so, he will jog

8 + 4 3/4 = 12 3/4 miles

on Friday.

don't forget, when we write something like 2 3/8. we actuality mean (2 + 3/8). and all rules about handling, transforming and calculating expressions apply.

therefore, e.g

2×(2 3/8) = 2×(2 + 3/8) = 4 + 6/8 = 4 6/8 = 4 3/4

The velocity of the rock is the number of feet traveled per second

The velocity of the rock is a linear function of time

From the question, we understand that the velocity increases by 32 feet per second for each second

This means that we have the following rates:

Velocity = 0, 32, 64, 96, 128....

Notice that the difference between adjacent numbers is 32.

This means that the velocity changes at a constant rate or slope

Hence, the velocity of the rock is a linear function
