centimeters.
What is the volume of the pyramid?
A. 624 cm3
B. 1,872 cm
C. 2, 808 cm
D. 4,212 cm
E. 8, 424 cm
Answers
Answer:
C. 2, 808 cm^3
Step-by-step explanation:
Given that
The base of the pyramid is 18 centimeters
And, the height of the pyramid is 26 centimeters
We need to find out the volume of the pyramid
As we know that
The volume of the pyramid is
= 1 ÷ 3 × base^2 × height
= 1 ÷3 × 18^2 × 26
= 2,808 centimeter^3
Hence, the correct option is c.

A company is testing a new protein shake which they claim works better than their existing brand in improving an athlete's performance. The company selected 60 athletes from a training camp database, and divided them into three groups. The ages for the groups were 16 to 20 years, 21 to 25 years, and 26 to 30 years. In each group, half of the subjects were asked to use the new protein shake for a month, and the other half were asked to use the company's existing brand for a month. The subjects were not informed about which protein shake they would be using. Which statements about this study are true? The study uses blocking to reduce variability from known factors. The study does not use a control group. The study uses random sampling. The study uses blocking on the basis of gender. The study uses a repeated measure design to reduce variability from unknown factors.

please help will mark brainliest
Answers
This is Bc 1=112 and 1 and 4 are virtual angles so 4 would also equal 112. And 4 and 6 are supplementary angles, and supplementary angles always add up to 180, and since 4 is 112 you’d subtract 112 from 180 and you’d get 68, so 6=68 and 6 and 8 are also supplementary angles so 8 would be 112
Solve this system of equations by using the elimination method. 2x - 2y = 2. 5x + 2y = 12 (2, [?])

Step-by-step explanation:
Answer:
17 - 42
18 - 50
Step-by-step explanation:
17)
You know the total measurement of both angles is 180.
So your formula is (2x+54) + x = 180. Now rearrange to get
180 - (2x+54) = x or 180-2x+54 =x
Simply to -2x+126 = x followed by moving x and moving 126 to get
-3x = -126 , now divide both sides by -3
18)
Your complete circle is 360 and you know one angle is 90.
Set your formula to 360=90+(3x)+(x-20)+(2x-10)
Rewrite to 360 = 90+3x+x-20+2x-10 and combine like terms
360 = 90 - 20 - 10 + 3x + x+2x
360 = 60 + 6x
360 - 60 = 6x
300 = 6x
300/6 = x
50 = x

The least common denominator is 12
=======================================================
Explanation:
Your teacher wants you to list the multiples of each denominator.
The multiples of 3 are: 3, 6, 9, 12, 15The multiples of 4 are: 4, 8, 12, 16, 20The values in bold are what will go in the boxes in those first two rows.
The least common denominator is 12 because it is the smallest thing found in common in the two lists above. In other words, 12 is the LCM (least common multiple) of 3 and 4. Note how 3*4 = 12. This works because 3 and 4 do not have any common factors between them other than 1.
The LCD (least common denominator) is the LCM of the denominators. The LCD is useful for when you want to add or subtract fractions. The denominators must be the same for you be able to add or subtract them.
What is the value of x for this triangle.
Answers
Answer:
13
Step-by-step explanation:
you have to use Pythagorean Theorem which is
(a^2) + (b^2) = (c^2)
where a and be are the legs 45° from each other and c is the hypotenuse.
so just plug in the numbers
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
now square root both sides to get rid of the square on c
root(169) = root(c^2)
13 = c
