Answer:

D

Step-by-step explanation:

First, we can find the volume of the rectangular prism.

As shown in the image, the dimensions are 4 by 4 by 9.

So,

4 * 4 * 9 = 144.

Now, we find the volume of the triangular prism.

As shown in the image, the dimensions are 3 by 4 by 9.

So,

3 * 4 * 9 = 108.

Now we add the volumes together:

144 + 108 = 252.

So, the answer is option D: 252 cubic meters.

Step-by-step explanation:

the ladder and the wall form a right angle triangle with sides a, b, and c. Remember that side c is the hypoteneuse, which is formed by the ladder in this case. the choice of which side is a and b is arbitrary. Solve for the missing side using pythagorean theorem.

[tex]c^2=a^2+b^2\\b^2=c^2-a^2\\b^2=17^{2}-5^{2}\\b^2=264\\b=\sqrt{264}\\b=16.25[/tex]

where side b is the height on the wall which the ladder reaches.

Answer:

m=5

Step-by-step explanation:

c=30m+50

c=20m+100

substitute

20m+100=30m+50

like terms

100-50=30m-20m

50=10m

m=5

Answer:

m = 5

Step-by-step explanation:

We know that c = c.

Since c is also equal to 30m+50 and 20m+100, 30m+50 = 20m+100 is just saying c = c. Then we solve that equation:

30m+50 = 20m+100

Same to both sides

10m = 50

divide by 10

m = 5

Answer:

Each cookbook cost $15.15.

Step-by-step explanation:

Since the statement indicates that four cookbooks and one novel cost $68.75, you can write the following equation:

4x+y=68.75, where:

x is the price of cookbooks

y is the price of novels

Also, given that the novel cost 7 dollars less than a cookbook, you can write the following equation:

x=y+7

Now, you can replace x=y+7 in the first equation:

4(y+7)+y=68.75

4y+28+y=68.75

5y=40.75

y=40.75/5

y=8.15

Now, you can replace the value of y in x=y+7:

x=8.15+7

x=15.15

According to this, the answer is that each cookbook cost $15.15.

Answer:

if you're rewriting the equation the answer is  x+2y+6=0 explanation : I moved the constant to the left handside and changed its sign, then divided both sides of the equation by 4. If youre solving for x the answer is x=-6-2y . If youre solving for y its y=-3- x/2 ( fraction)

Constant of proportionality(X:Y) = 1:6

Step-by-step explanation:

Given:

Y- 30, 36, 42, 48, 54

Find:

Constant of proportionality

Computation:

X/Y = 5/30 = 6/36 = 7/42 = 8/48 = 9/54

X/Y = 1/6 = 1/6 = 1/6 = 1/6 = 1/6

So;

Answer:

18k + 22p -10

Step-by-step explanation:

The solution is Option B

The equation to represent the total cost for Mr.Thompson to rent a kayak for k hours and paddle board for p hours is A = 18k + 22p - 10

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the cost of renting a kayak per hour be = $ 18

Let the number of hours of renting the kayak be = h

Let the cost of renting a paddle board per hour be = $ 22

Let the number of hours of renting the paddle board be = p

Let the discount of cost as coupon = $ 10

Now , the total cost of renting at Cycle and Sports for Mr. Thompson A =
( cost of renting a kayak per hour x number of hours of renting the kayak ) +
( cost of renting a paddle board per hour x number of hours of renting the paddle board ) -  discount of cost as coupon

Substituting the values in the equation , we get

Total cost for Mr.Thompson to rent a kayak for k hours and paddle board for p hours A = 18h + 22p - 10

Therefore , the value of A is 18h + 22p - 10

Hence , the equation for total cost is A = 18h + 22p - 10

Answer:

D.) 9√2

Step-by-step explanation:

a^2 + b^2 = c^2

x^2 + 8^2 = √226^2

x^2 + 64 = 226

x^2 = 226 - 64

x^2 = 162

√x^2 = √162

Answer:

0.10s

Step-by-step explanation:

Given data

DIstance= 6.5ft

velocity = 64 feet per second

with the parameters given above, we can find the time taken as

velocity = distance/time

time= distance/velocity

time= 6.5/64

time= 0.10 seconds

Hence the time the ball took is 0.10s

Answer:

6/9

Step-by-step explanation:

So the points show a linear function, meaning that since they make a line, if you have just one x or y coordinate, you're able to find out the other one by looking at the graph. At the first point, there are 4 apples and 6 oranges. If we write this as a ratio of apples to oranges in fraction form, it would be 4/6. This can be simplified to 2/3, which is also known as the slope, and is going to be the same for all of the points on the line, so we can use this to check our answer. If he makes a basket with 6 apples, we use the ratio we found earlier to find how many oranges he'd have. We set it up like this: 6/x=2/3. Then we multiply 6 and 3 (=18), and divide by 2 (=9). So the number of oranges is 9, written as a fraction is 6/9.
