Answer:

  A and B

Step-by-step explanation:

Speed is the change in distance divided by the change in time. That is, it is the slope of the distance vs. time curve. A steeper slope corresponds to a greater speed.

Between A and B, the slope is (30-0)/(1-0) meters/time-unit = 30 m/u.

Between B and C, the slope is (30-10)/(4-1) = 20/3 = 6 2/3 m/u.

Between C and D, the slope is 0.

Between D and F, the slope is (50-10)/(10-6) = 40/4 = 10 m/u.

The greatest slope is between A and B.

The object has the greatest speed between points A and B.

Answer:

1 1/2

Step-by-step explanation:

set up a proportion:

8 = 12

1        x

cross-multiply:  8x = 12

                          x = 12/8

                          x = 3/2 (simplified)

Answer:

Part A: 14

Part B: 10

Step-by-step explanation:

Since the ratio to each paint is the same...

(red/yellow) 2/5=x/35

Cross Multipy

5x=70

x=70/5

x=14

Repeat the same thing but replace 35 with 25 for Part B

2/5=x/25

Cross Multiply

5x=50

x=10

Answer:

[tex]-12x^2[/tex]

Step-by-step explanation:

Think of the box method as completing a chart or a multiplication table.

We can see that box B is in the second column of the first row. The second column is labeled by -4x. The first row is labeled by 3x. So, in order to fill out box B, you have to multiply -4x and 3x together.

To do so, multiply the terms' coefficients (the numbers in front of the variable). -4 times 3 makes -12. Then, multiply the variables - just keep the variable and add their exponents. x and x both have exponents of one, which makes [tex]x^1^+^1[/tex], resulting in [tex]x^2[/tex]. Put them together and the answer would be [tex]-12x^2[/tex].

Answer:

0u

7u

6u

2u

Step-by-step explanation:

All of these question are just a matter of adding like terms

For the first one we have

7u+(-u)+(-6u)

which is equal to

7u-u-6u

Which I'm sure you can see is equal to 0 or 0u

10/2u+2u

10/2u=5u

5u+2u=7u

6u+0u

0u=0

6u

6u+(-4u)

6u-4u

2u

Answer:

easy pz hot eggs are cheesy, 1 is 0u number 2 is 7u number 3 is 6u and number 4 is 2u

Step-by-step explanation:

Salvador sold hats during a weekend sporting event. On Saturday, Salvador sold 4/7 of the total number of hats. On Sunday, he sold 1/4 of the total number of hats. What fraction of the total number of hats was left over

Total number of hats = x

Hats sold on Saturday = 4/7x

Hats sold on Sunday = 1/4x

Hats left over = x - (4/7x + 1/4x)

= x - ( 16x+7x/28)

= x - 23/28x

= 28x - 23x/28

= 5/28x

Answer:

Answer choice D

Step-by-step explanation:

So we need to get r to the right side. First we can multiply by 3 to get rid of the fraction:

3V=4[tex]\pi[/tex][tex]r^{3}[/tex]

Then we can divide both sides by 4[tex]\pi[/tex] to get r by itself:

[tex]\frac{3V}{4\pi } = r^{3}[/tex]

Then cube both sides:

[tex]\sqrt[3]{\frac{3V}{4\pi } } =r\\[/tex]

Answer choice D

Answer:

The partial sums are increasing in value.

The series converges to the same value as what the partial sums approach.

The partial sums appear to approach 0.33.

The series might converge to One-third.

Answer:

[tex]0.10d + 0.25q > 143.88[/tex]

Step-by-step explanation:

Let the total dimes collected be d.

[tex]1\ dime = \$0.10[/tex]

[tex]d\ dimes = \$0.10d[/tex]

Let the total quarters collected be q.

[tex]1\ quarter = \$0.25[/tex]

[tex]q\ quarters = \$0.25q[/tex]

[tex]Last\ Year = \$143.88[/tex]

Required

Represent as an inequality

The total collection, this year, can be represented as:

[tex]Total = 0.10d + 0.25q[/tex]

From the question, we understand that:

This year's collections is expected to be greater than last year's

This can be represented as:

[tex]Total > Last\ Year[/tex]

Substitute in the right values:

[tex]0.10d + 0.25q > 143.88[/tex]

Step-by-step explanation:

2. 10x - 3 + 2x - 5 and 4(3x - 2)

10x - 3 + 2x - 5

Upon simplifying;

10x + 2x - 3 - 5

12x - 8

4(3x - 2)

12x - 8

Both expressions are equivalent - Yes!

3. 3y + 3 and 9(y + 1/3)

9(y + 1/3)

upon simplifying;

9y + 9 (1/3)

9y + 3

3y + 3

Both expressions are not equivalent - No!

4. 6(3x + 1) and 9x + 6 + 9x

6(3x + 1)

upon simplifying;

6(3x) + 6 (1)

18x + 6

9x + 6 + 9x

Upon simplifying;

9x + 9x + 6

18x + 6

Both expressions are equivalent - Yes!

Answer:

(-2,-10)

Step-by-step explanation:

So if y=5x and if y=9x+8 then those should be able to equal each other (substitution):

5x=9x+8

Subtract 5x from both sides:

0=4x+8

Subtract 8 from both sides:

-8=4x

Divide both sides by 4:

x=-2

If x=-2, then we can just plug it back into the first equation:

y=5(-2)

Simplify:

y=-10

Answer:

x = -2

y = -10

Step-by-step explanation:

So if y = 5x

Then you can put that in place of the y

5x = 9x + 8

Get the x's all on one side by subtracting

-4x = 8

Divide both sides by -4

x = -2

Then insert x into the first equation, so

y = 5(-2)

y = -10

Answer:

Glass of milk=15 carbs

One snack bar=11 carbs

Step-by-step explanation:

×2 2m+3s=63.......................1

×1 4m+2s=82..............2

4m+6s=126

4m+2s=82

Cancel out the 4ms

6s=126

2s=82

minus top and bottom equations and remain with

4s= 44

s=44/4

s=11 ∴ one snack bar is 11 carbs

subs s=11 into equation 1

2m+3s=63

2m+3(11)=63

2m+33=63

2m=63-33

2m=30

m=30/2

m=15  ∴one glass of milk is 15 carbs
