Answer:

h'(t)=88

Step-by-step explanation:

h'(t)=d/dt (-16t x 2 + 120t + 10

h'(t)=d/dt (-32t + 120t + 10)

h'(t)=d/dt (88t + 10)

h'(t)=d/dt (88t) + d/dt (10)

h'(t)=88 + 0

Answer:

128.125

Step-by-step explanation:

64%=64/100

64/100 = 82 cars

1 = 82÷64/100

=82×100/64

=41×25/8

=1025/8

Division is one of the four fundamental arithmetic operations. The number of days this cat food will last is 14 days.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Given that each cat eats 1/4 of a tin of cat food each day. Therefore, the amount of food that two cats will eat in a day is,

= 2 ×  1/4 of a tin of cat food each day

= 1/2 of a tin of cat food each day

Further, it is given that Sally buys 7 tins of cat food. Therefore, the number of days this cat food will last is,

= Total cat food / Cat food needed in a day

= 7tin of cat food / 1/2 of a tin of cat food each day

= 14 days

Hence, the number of days this cat food will last is 14 days.

Answer:

The ratio of the songs is 5:3

Step-by-step explanation:

This means that for every 5 songs Adam has, his mother has 3. We can do that in intervals of 5:3, with 10:6, 15:9, 20:12, and etc.

Write "15" in Adam's column and "24" in his mother's column.

In the given question, the table of equivalent ratios is missing. Please find the attachment of that table below.

Given ratio is:

The ratio of Adam's songs to his mother's songs,

then,

→  [tex]\frac{Adam's \ songs}{Mother's \ songs} =\frac{5}{3}[/tex]

→ [tex]Adam's \ songs = \frac{5}{3}\times 9[/tex]

→                         [tex]= 15[/tex]

Now,

→       [tex]\frac{40}{Mother\s \ songs} =\frac{5}{3}[/tex]

→                [tex]40\times \frac{3}{5} = Mother's \ songs[/tex]

→ [tex]Mother's \ songs = 24[/tex]

Thus the above approach is right.

Slope is equal to rise over run

You can look at the graph and see to get to from point (-3, -1) to point (2, 4) you rise up (change in y) 5 units and run (change in x) 5 units. This means the slope is 5 / 5 which is equal to 1.

Answer:

I believe is A.

Step-by-step explanation:

you will have x^2 (which is the big square) + 1x (which is the lower line) + 3x (which are the 3 line verticals) + 3 (which are the 3 squares)

Answer: Choice A

Across the top we have x+3 since the square has side length x and the long rectangles have their short side equal to 1. Three of those rectangles combined like that make 1+1+1 = 3

Across the far left side, we have a vertical distance of x combined with just 1 this time (instead of 3) leading to x+1

Answer: Non proportional

Step-by-step explanation:

To know if the values given are proportional or not, we will use the formula:

y = kx

where

y = number of organisms

x = number of minutes

k = constant of proportionality

After 5 minutes, a bacteria colony has 1.3 million organisms. Using the formula, y = kx

1,300,000 = 5k

k = 1,300,000 / 5

k = 260,000

After 12 minutes, the same colony has 41.5 million organisms. Using y= kx

41,500,000 = 12x

x = 41500000 / 12

x = 3458333.8

After 15 minutes, the colony has grown to 101.3 million organisms.

y = kx

101,300,000 = 15k

k = 101,300,000 / 15

k = 6753333.8

It is a non-proportional relationship as the constant of proportionality is different for each.

Answer:

3/8

Step-by-step explanation:

7/8 - 1/2 = ?

First, we find the Least Common Denominator and rewrite the fractions with the common denominator.

(7/8 × 1/1) - (1/2 × 4/4)

= 7/8 - 4/8 = ?

Now that the denominators are the same, we can subtract the numerators.

7-4/8 = 3/8

This fraction can't be reduced since it is already in its simplest form. Therefore, 7/8 - 1/2 = 3/8

Answer:

[tex]\frac{2}{7}[/tex]

Step-by-step explanation:

Simplify the numerator and the denominator.

The square root of 4/49 is 2/7.

Given that a fraction 4/49 we need to find the square root of this fraction,

To find the square root of a fraction, you need to find the square root of both the numerator and the denominator separately. Let's apply this to the fraction 4/49.

Step 1: Find the square root of the numerator:

The numerator is 4. Taking the square root of 4 gives us √4 = 2.

Step 2: Find the square root of the denominator:

The denominator is 49. Taking the square root of 49 gives us √49 = 7.

Step 3: Form the new fraction:

The square root of the fraction 4/49 is (√4)/(√49), which is 2/7.

Therefore, the square root of 4/49 is 2/7.

Answer: The answer is D

Step-by-step explanation:

I used desmos graphing calculator! Look it up it really helps! Literally gives the answers. :)

Answer:

7 boxes

Step-by-step explanation:

Let x represent the amount of cookies that was brought to the party by Kendall

Each box contain 12 cookies

= 12 × x

= 12x

Kendall keeps 2 boxes for herself

= 12 × 2

= 24

Kendall has 60 cookies which she took to the party

Therefore the question can be represented as follows

12x = 24+60

12x= 84

Divide both sides by the coefficient of x which is 12

12x/12= 84/12

x= 7

Hence Kendall brought 7 boxes

Answer:

Adrian lives closer to the school by A. 1,250 meters.

Step-by-step explanation:

1 kilometer = 1,000 meters

So, if Kevin's home is 2 kilometers from the school, then it is also 2,000 meters away, since  1,000 x 2 = 2,000.

Adrian lives 750 meters, or 0.75 kilometers away from school.

2,000 - 750 = 1,250.

Therefore, Adrian lives closer to the school by A. 1,250 meters.

Answer: I believe the answer is C

The system of linear equations that represents the given situation is (d + h = 80) and (d = 2h - 10) and this can be determined by using the given data.

Given :

The following steps can be used in order to determine the system of equations models given situation:

Step 1 - Let the total number of cookies Duc baked be 'd' and the total number of cookies Hue baked be 'h'.

Step 2 - The linear equation that represents the total number of cookies Hue and Duc baked is:

d + h = 80

d = 80 - h  --- (1)

Step 3 - The linear equation that represents that Duc baked 10 less than twice the number of cookies Hue baked is:

d = 2h - 10  --- (2)

Step 4 - Substitute the value of 'd' in equation (2).

2h - 10 = 80 - h

Step 5 - Simplify the above expression.

3h = 90

h = 30 cookies

Step 6 - Substitute the value of 'h' in equation (1).

d = 80 - 30

d = 50 cookies

Therefore, the correct option is C).

Answer:

h(x) = 5x+6

Step-by-step explanation:

h(x) = f(x) - g(x)

h(x) = 3x+2 - (-2x-4)

h(x) = 3x+2 + 2x+4

h(x) = 5x+6

All we need to do is plug in the equations for f(x) and g(x) into h(x)

Let's do it

f(x) = 3x + 2 and g(x) = -2x -4

h(x) = f(x) - g(x)

h(x) = (3x + 2) - (-2x - 4)

Combine like terms

(3x) - (-2x) →     3x + 2x      → 5x

(+2) - (-4) →      2 + 4     → 6

Let's put them together

h(x) = 5x + 6

Answer:

Answer:

13/20

Step-by-step explanation:

You can write 1 1/4 as 5/4.  Any fraction that has the same number in the numerator and the denominator equals 1.  For example 4/4 = 1, 20/20 =1, 5/5 = 1 and so on.

I can rewrite 1 1/4 as 4/4 + 1/4 = 5/4

Now we want to add -3/5 and 5/4.  We need a common denominator because the pieces of the fractions are not equal.  The smallest number that 5 and 4 will go into is 20.  Si U an going to write the two fractions with 20 as the denominator.

-3/5 = -12/20  I multiplied the top and the bottom of -3/5 with 4.

5/4 = 25/20  I multiplied the top and the bottom of 5/4 by 5

-12/20 + 25/20 = 13/20
