16 / 4 = 4 cars  and 24 / 3 = 8 boats  there are 8boats in each group and 4 cars in each group the answer is There are 4 more toy boats in each group than toy cars.
Usimov [2.4K]3 years ago

Well first we divide 16 by 4 because we have to split the cars up equally in 4 groups and the answer we get to that is 4 so there are 4 cars in each group. Now we do the same for the boats we take 24 and divide by 3 and get 8, so there are 8 boats in each group. Now we take the toy boats in one group because there are obviously more of them and subtract the cars that are in one group and get a difference of 4 which is the answer

8. Lesly took a test with 30 questions. The ratio of correct answers to incorrect answers
Firlakuza [10]

Lesly got 14 answers correctly.

  • Let the correct answers be C.
  • Let the incorrect answers be I.

<u>Given the following data:</u>

  • Total number of questions = 30 questions.
  • Ratio of C to I = 7 : 8
  • C to I = 7 + 8 = 15

To find the number of answers she got correctly;

C = \frac{7}{15} × 30

C = 7 × 2

<em>Correct answers, C </em><em>= </em><em>14 answers</em>

Therefore, Lesly got 14 answers correctly.

Find the value of x.<br><br> A.<br> 7<br> B.<br> 9<br> C.<br> 11<br> D.<br> 12
Arisa [49]
Use the law of cosines to solve for angle A. Plug your known side length values into the equation a^2 = b^2 + c^2 – 2bc cos A.

Then use the law of sines to find angle B. (Sin A/a = Sin B/b = Sin C/c).

Because the two red angles within B are congruent, divide your angle measure in half.

From there, do the law of sines to solve for x. Good luck!

Consider the two expressions 4b(b+1) and (2b+7)(2b-8). Compare their values if b=-3, b=-2, and if b=10. Is it true that for an v
frutty [35]

Answer:

FIRST EXPRESSION:

-  If b=-3, the value of 4b(b+1) is  24

-  If b=-2, the value of 4b(b+1) is  8

- If b=10, the value of 4b(b+1) is  440

 SECOND EXPRESSION:

-  If b=-3, the value of (2b+7)(2b-8)) is  -14

-  If b=-2, the value of (2b+7)(2b-8)) is  -36

- If b=10, the value of (2b+7)(2b-8)) is  324

Yes, for any value of "b" the value of the first expression is greater than the value of the second expression.

Step-by-step explanation:

Substitute the given values of "b" into each expression and evaluate.

- For the first expression 4b(b+1), you get:

If b=-3 → 4(-3)(-3+1)=24

If b=-2 → 4(-2)(-2+1)=8

 If b=10 → 4(10)(10+1)=440

 - For the second expression (2b+7)(2b-8)), you get:

If b=-3 → (2(-3)+7)(2(-3)-8)=-14

If b=-2 → (2(-2)+7)(2(-2)-8)=-36

 If b=10 → (2(10)+7)(2(10)-8)=324

You can observe that for any value of "b" the value of the first expression is greater than the value of the second expression.

10c - cd + d^3 (if c = -6 and d= 2)
mash [69]

The required simplified solution of the given expression is -40.

Given that,
To determine the simplified solution of the given expression 10c - cd + d³ at c = -6 and d = 2.

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
= 10c - cd + d³

Substitute the values,
= -60 + 12 + 8
= -40

Thus, the required simplified solution of the given expression is -40.

A table top in the shape of a trapezoid has an area of 2250 square centimeters and the shorter base is 80 centimeters. The longe
Citrus2011 [14]
The area of a trapezoid has a formula of:
Area = (a + b) h / 2

Using the formula, we can easily find the height of the trapezoid.
<span>Area = (a + b) h / 2
</span>2250 = (80 + 100) h / 2
2250 = 180h / 2
2250 = 90h
h = 25 centimeters

So the height of the trapezoid is 25 centimeters.
