As part of her art project, Sarah is painting 2 square
pyramids. The first pyramid has a base with a length of 6
cm and lateral faces with heights of 8.5 cm. The second
pyramid has a base that is half the length of the first
pyramid, and each lateral face has a height of 8.5 cm. What
is the surface area of the second pyramid?

Answers

Answer 1

Answer:

25.5

Step-by-step explanation:

first pyramid: 6*8.5

second pyramid: 3 (half the length of the first) *8.5

3*8.5 = 25.5

Answer 2

Answer:

25.5

Step-by-step explanation:

There are multiple squares you need to find the area of each one by finding the area of each square then adding them together to get the surface area.

Jordon missed 49 on his multiple choice math final and earned a grade of 65%. How many total questions were on the final exam?

Answers

Answer:

The exam was out of 75.

Step-by-step explanation:

You know that he earned 65% so more than half his answers were correct.

Then, you would guess and check try 49/60, 49/70, and go up by 10s or 5s. You will then realize that 49÷75 equals 65.333. This rounds up to 65.

The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate? Need help fast!!!

Answers

Answer:

2 kittens per crate

Step-by-step explanation:

The kittens in a room at an animal shelter are arranged in five crates, as shown.

The manager of the shelter wants the kittens distributed equally among the crates. How might that be done? How many kittens will end up in each crate?

Crate 1 = 2 kittens

Crate 2 = 1 kitten

Crate 3 = 4 kittens

Crate 4 = 3 kittens

Crate 5 = 0 kitten

Total kittens = 2 + 1 + 4 + 3 + 0

= 10 kittens

To distribute them equally among the crates, divide the number of kittens by the number of crates

Kitten per crate = number of kittens / number of crates

= 10 kittens / 5 crates

= 2 kittens per crate

Kitten per crate = 2 kittens per crate

Express the lcm of 50,18 and 32 in prime factors​

Answers

Answer:

The least common multiple of 50, 18 and 32 is 7200.

Step-by-step explanation:

mark brainleist plz

Answer:

LCM = 7200

Step-by-step explanation:

LCM(18, 32, 50) =

LCM(LCM(18, 32), 50)

Working from the innermost parentheses outward:

LCM(18,32) = (18 × 32) / GCF(18,32)

= (18 × 32) / 2

= 576 / 2

= 288

LCM(288,50) = (288 × 50) / GCF(288,50)

= (288 × 50) / 2

= 14400 / 2

= 7200

Therefore,

LCM(18, 32, 50) = 7200

Answers

Question:

Plot two points that are 8 units from Point B and also share the same x-coordinate as Point B

See attachment for grid

Answer:

See attachment for plot

Step-by-step explanation:

See comment for complete question

From the attached image, we have:

[tex]B = (-6,0)[/tex]

Required

2 points that are 8 units away and on the same x coordinate

Let the two points be [tex]C\ and\ D[/tex]

The first condition is that; C and D must be on the same x coordinate as B.

So, we have:

C = (-6,_)

D = (-6,_)

8 units from B implies that we add or subtract 8 from the y coordinate of B.

So, we have:

[tex]C = (-6,0+8)[/tex]

[tex]D = (-6,0-8)[/tex]

[tex]C= (-6,8)[/tex]

[tex]D= (-6,-8)[/tex]

Suppose that 20% of all students in a school make the Honor Roll. Which simulation best models a way to show how
students can be randomly selected and identified as being on the Honor Roll? WHY is that the best simulation?

A) Put 10 marbles in a bag, 8 red and 2 yellow. Draw out a marble at random 100 times, replacing the marble each
time.

B) Divide a spinner into 4 equal parts, labeled 1-4. Spin it 100 times. Let an even number represent Honor Roll and
an odd number represent not on the Honor Roll.

PLEASE REMEMBER TO STATE WHY

Answers

Answer:

A)

Step-by-step explanation:

The problem stated that 20 percent got in honor roll.

The key word in the problem is randomly selected.

Out of a and b, it's simply crossing out one of them.

B doesn't make sense, since if you spun a spinner 100 times, each side would have a probability of 25 percent. And that's if you only used one of the parts as an odd number.

Another way to think of it is that there are 2/10 yellow marbles, and 8/10 red.

2/10=20 percent.

8/10=80

In circle D, angle ADC measures (7x + 2)°. Arc AC

measures (8x - 8)º.

What is the measure of angel ABC

Answers

Answer:

The measure of angle ABC is 36° ⇒ 1st answer

Step-by-step explanation:

Let us revise some important facts in the circle

The measure of the center angle is equal to the measure of its subtended arc

The measure of the inscribed angle is equal to half the measure of the central angle subtended by the same arc

The vertex of a central angle is the center of the circle and its sides are radii in the circle

The vertex of an inscribed angle is a point on the circle, and its sides are chords in the circle

In circle D

∵ D is the center of the circle

∵ A and C lie on the circle

- DA and DC are radii

∴ ∠ADC is a central angle subtended by arc AC

∴ m∠ADC = m of arc AC

∵ m∠ADC = (7x + 2)°

∵ m of arc AC = (8x - 8)°

- Equate them to find x

∴ 8x - 8 = 7x + 2

- subtract 7x from both sides

∴ x - 8 = 2

- Add 8 to both sides

∴ x = 10

Substitute the value of x in the measure of ∠ADC

∵ m∠ADC = 7(10) + 2 = 70 + 2

∴ m∠ADC = 72°

∵ AB and BC are two chords in circle D

∴ ∠ABC is an inscribed angle subtended by arc AC

∵ ∠ADC is a central angle subtended by arc AC

- By using the 2nd fact above

∴ m∠ABC =  m∠ADC

∴ m∠ABC =  × 72

∴ m∠ABC = 36°

The measure of angle ABC is 36 degrees

Circle geometry

To get the required measure of m<ABC, we will use the theorem that states that the measure of the central angle is equal to the measure of its subtended arc and;

The vertex of a central angle is the center of the circle and its sides are radii in the circle

According to the given circle D

∠ADC is a central angle subtended by arc AC

m∠ADC = m of arc AC

m∠ADC = (7x + 2)°

m of arc AC = (8x - 8)°

Equate to find the value of x

8x - 8 = 7x + 2

x - 8 = 2

x = 10

Substitute the value of x in the measure of ∠ADC

m∠ADC = 7(10) + 2 = 70 + 2

m∠ADC = 72°

∠ADC is a central angle subtended by arc AC

m∠ABC =  0.5 × 72

m∠ABC = 36°

Hence the measure of angle ABC is 36 degrees

A class of 30 swim team members took a lifesaving test. Eighteen of the members had an average score of 92 points. The remaining members had an average score of 84 points.

What was the average for the entire swim team?

Answers

Answer:

Step-by-step explanation:

1.) 30-18= 12 which is the number of member that had an average of 84

2.)Then multiply  12 times 84 = 1008

3.) You multiply 18 by 92 which equals 1656

4.)Add 1008 and 1656 together  and get 2664.

5.)Divide 2664 / 30 and you get the average of 88.8

Maria is making a fruit punch. There are 15.75 ounces of orange juice in a container. Maria pours 2.25 ounces of cranberry juice into the container each second. How many ounces of fruit punch are in the container after 9 seconds?

Answers

Answer:

20.25 ounces

Step-by-step explanation:

We are given 2.25 ounces of cranberry poured into the container per second. We need to find is how much that is after 9 seconds. (Note: This is different from the 15.75 ounces of orange.) There are many ways to solve this question (e.g If 2.25 is 1, then multiply 2.25 and 9 = 20.25) Now to solve this let's set up fractions; let "x" be the variable;

[tex]\frac{1}{2.25}=\frac{9}{x}[/tex]

Apply fraction: if [tex]\frac{a}{b}=\frac{c}{d}\mathrm[/tex]  then [tex]a\cdot \:d=b\cdot \:c[/tex] (meaning cross multiply)

[tex]1\cdot \:x=2.25\cdot \:9[/tex]

Simplify

Multiply by 1

[tex]1 x = 2 . 2 5 \cdot 9 \\\\ x = 2 . 2 5 \cdot 9[/tex]

Multiply the numbers

[tex]x = 2 . 2 5 \cdot 9\\\\x=20.25[/tex]

Therefore, there are 20.25 ounces of fruit pouch in the container after 9 seconds.
