A line passes through the points (3,21) and (7,25) Write a linear function rule in terms of x and y for this line.

Answer:

total blocks are 20 and prisms are 28

Step-by-step explanation:

There are 20 blocks needed for tower A, and 43.75 blocks needed for tower B

From the tape diagrams, we have the following ratio

Prism : Pyramid = 4 : 1

From the table, we have:

Tower A = 16 prisms

So, the ratio becomes

16 : Pyramid = 4 : 1

Multiply the ratio on the right-side by 4

16 : Pyramid = 16 : 4

By comparison, we have:

Pyramid = 4

This means that, 4 pyramid blocks are needed for tower A

So, the total number of blocks needed is:

Total = Pyramid + Prism

This gives

Total = 4 + 16

Evaluate the sum

Total = 20

Hence, there are 20 blocks needed for tower A

For table B, we have:

Tower A = 35 prisms

So, the ratio becomes

35 : Pyramid = 4 : 1

Express as fractions

[tex]\frac{Pyramid}{35} = \frac 14[/tex]

Multiply through by 35

Pyramid = 8.75

This means that, 8.75 pyramid blocks are needed for tower B

So, the total number of blocks needed is:

Total = 8.75 + 35

Evaluate the sum

Total = 43.75

Hence, there are 43.75 blocks needed for tower B

Answer:

I believe that the answer is x=24

Answer:

$35526 is the cost of the model

Step-by-step explanation:

We can multiply 31,000 by 14.6 percent, and then add that to 31,000 to get our answer.

Step 1:

Convert 14.6% into a decimal. 0.146

Step 2:

Multiply 31,000 by 0.146

[tex]31000*0.146=4526[/tex]

Step 3:

Add 4526 and 31,000.

This equals 35526.

Answer:

  B.

Step-by-step explanation:

I would write the first equation to better match the wording: three times d is 3d, and 290 less is (3d -290). That is said to be equal to t:

  t = 3d -290

If 3d is subtracted from both sides of this equation, you get an equation that matches some of the answer choices:

  t -3d = -290

The other equation is a straightforward expression of the difference in prices:

  t -d = 240

These equation match choice B.

  IS a function

Step-by-step explanation:

The ordered pairs are (input, output). Essentially, the numbers in each ordered pair are the numbers at each end of an arrow. There are as many ordered pairs as there are arrows.

Working top-down on input values, the ordered pairs of this relation are ...

  (10, 1), (15, 1), (20, 13), (25, 7)

None of the input values is repeated, so the relation is a function.

Answer:

y = 15

Step-by-step explanation:

The triangles follow a scale factor. This scale factor can enlarge or make a triangle smaller, using this factor, like a ratio. We can do 22/10 to get this scale factor for the set, which is 2.2. Finally, divide 33 by 2.2 to get 15 for the missing side length y.

Answer:

(-8,-10)

Step-by-step explanation:

we have the two equations x-2y=12 and y=3x+14.

I'm going to assume this is a system of equations and we are looking for the solution.

we can use the substitution method as y is "defined".

x-2y= 12

substitute y = 3x + 14

x-2(3x+14)=12

distribute

x - 6x -28 = 12

combine like terms

-5x - 28 = 12

add 28 to both sides

-5x = 40

divide both sides by -5

x = -8

Now we plug in the value of x into one of the equations and solve for y

y = 3x + 14

x = -8

y = 3(-8) + 14

y = -24 + 14

y = 10

the solution is (-8,-10)

Answer:

Step-by-step explanation:

The required speed in km/hr are 108km/hr and 25.704km/hr

Given the following conversion rate

Given that the speed of cheetah is 30meters per second. Converting to m/s will give:

30m/s = [tex]\frac{30m}{1s} \times \frac{1km}{1000m} \times \frac{3600s}{1hr} \\[/tex]

30m/s = 30 * 3.6

30m/s = 108km/hr

For the person with speed of 7.14m/s, the value in km/hr is expresssed as:

7.14m/s = 7.14 * 3.6

7.14m/s = 25.704km/hr

Hence the required speed in km/hr are 108km/hr and 25.704km/hr
