volume = 0.5 * b * h * length
So 0.5*1 1/2*2*4 =6
V=6
volume =0.5* b* h * length
So 0.5*1 1/2*2*4 =6
Volume=6cm^3

Solution


a.) y = 15x - 50
when x = 7


b.) y = 1/2x + 20
when x = 50


c.) y = (3x)2 - 36
when x = 3


d.) y = 2.5x + 3.8
when x = 0.66

Answers

Answer:

a) y = 55

b) y = 45

c) y = -18

d) y = 5.45

Step-by-step explanation:

y = 15x - 50    when x = 7

y = 15(7) - 50

y = 105 - 50

y = 55

y = 1/2x + 20   when x = 50

y = 1/2(50) + 20

y = 25 + 20

y = 45

y = (3x)2 - 36    when x = 3

y = (3(3))(2) - 36

y = 9(2) - 36

y = 18 - 36

y = -18

y = 2.5x + 3.8    when x = 0.66

y = 2.5(0.66) + 3.8

y = 1.65 + 3.8

y = 5.45

An engineer needs to create a bridge that consists of right triangles for support. Determine whether the triangle shown is a right triangle.
Be sure to include your answer and show/explain the steps you used to solve.​

Answers

Answer:

See below

Step-by-step explanation:

We can see that the thick line which outlines the main cable, the base and tower form a triangle

The longest length is the main cable which is 15m

If it is indeed a right triangle. the squares of the sums of the two shorter sides must equal the square of the longer side.

Sum of squares of shorter sides(also called legs) = 9² + 12²

= 81 + 144

= 225

Square of the longer side = 15² = 225

Since 15² = 9² + 12²

the triangle shown is indeed a right triangle with hypotenuse = 15m and the legs of the right triangle  9m and 12m

Can someone explain 3, 4, and 5 ?

Answers

Answer:

3. B

Step-by-step explanation:

3. B

This is because if you find the GCF of 6 and 12 you will get 3.

3(p+m) hence why three is at the beginning.

you will then divide 6 and 12 by three and put them inside the parentheses with their corresponding variable.

3(2p+4m)

if you multiply this you will get

6p+ 12m

Answer:

Step-by-step explanation: for 3 you have yo find what is equivalent to 6p+12m so the answer is c. 6(p+12M) for 4 you are explaining what will happen if g is 1 and g is 3.  for 5 you have to explain what is the constant rate.

I'm not lying on skz <------ If i do it on skz y'know I'm not lying

Answers

y = (1/6)x + 7

y = mx + b is the slope intercept equation

slope (m) = 1/6 which is rise/run so up 1, and right 6

point (-6, 6) means x = -6 and y = 6

substitute variables to see what is left to find.

6 = (1/6)(-6) + b --> solve for b.

6 = -1 + b --> 7 = b *** now reapply to slope intercept form with the exception of points (x, y) to obtain slope intercept formula.

y = (1/6)x + 7

Answer: 10x = 4 is x = 0.4.

To solve the equation 10x = 4, we want to isolate the variable x on one side of the equation.

First, we divide both sides of the equation by 10:

10x / 10 = 4 / 10

Simplifying:

x = 0.4

Therefore, the solution to the equation 10x = 4 is x = 0.4.

A large container has a maximum capacity of 64 ounces. The container is filled with 8 ounces less than its maximum capacity. Answer parts a and b.
a. To what percent of its capacity is the large container​ filled?

The container is filled to 87.5​% of the maximum capacity.

b. Some liquid will be poured from a full​ 16-ounce container until it is filled to the same percent of its capacity as the large container in part a. How many ounces of liquid must be poured from the full​ 16-ounce container? Explain.

Note: The answers go in the blanks

When the​ 16-ounce container is _____% ​filled, it will contain _____ ​ounce(s). So _____ ounce(s) will need to be poured from the full​ 16-ounce container.

Answers

Answer:

  (a)  87.5%

  (b)  90%, 14.4 oz, 1.6 oz

Step-by-step explanation:

You want the fraction full a 64 oz container is if it holds 8 oz less than its capacity. You also want to know the amount that must be transferred from a 16 oz container if both containers are to be the same fraction full.

a) Fraction

The amount in the 64-ounce container is ...

  64 oz - 8 oz = 56 oz

The fraction of its capacity this represents is ...

  (56 oz)/(64 oz) = 7/8 = 87.5%

The container is filled to 87.5% of its capacity.

b) Transfer

If x is removed from a 16-ounce container and added to the 64-ounce container, their respective fill fractions are ...

  (16 -x)/16   and   (56 +x)/64

We want these values to be equal, so ...

  (16 -x)/16 = (56 +x)/64

  4(16 -x) = 56 +x . . . . . . . . . multiply by 64

  64 -4x = 56 +x . . . . . . . . . eliminate parentheses

  8 = 5x . . . . . . . . . . . . . . . . add 4x-56

  x = 8/5 = 1.6 . . . . . . . . . . . divide by 5

When 1.6 ounces are removed from the 16-ounce container, its fill fraction will be ...

  (16 -1.6)/16 = 1 - 0.1 = 0.90 = 90%

The 16-ounce container will be 90% filled, and will contain 14.4 ounces.

So, 1.6 ounces will need to be poured from the full 16 ounce container.

__

Additional comment

After receiving 1.6 ounces, the larger container will have 57.6 ounces. Its fraction full will be 57.6/64 = 90%, as required.

Answers

Step-by-step explanation:

Since Elsa is running at 2 and Anna at 1.75, we can first subtract

2 - 1.75 = 0.25, meaning each second Else gains 0.25m

Now that Anna was given a 10m headstart, we can divide 10 by 0.25

10/0.25 = 40

Meaning it would take 40 seconds for Elsa to catch up

the answer is 40, enjoy lol
