30 pts! Take a look at this square pyramid (image included). What is the surface area?

Answer:

22.5

Step-by-step explanation:

With similar triangles you don't have to solve for any angle, as both triangles are alike, just different sizes in the case. So 20/12 = 5/3 or 1.66, and the same for 27.5/16.5, so using that, we have 37.5/1.66 which is 22.5

Answer: 104.65%

Step-by-step explanation: 45/43=1.0465 so you just move the decimal to the right 2 places to make it a percent. It’s over 100% because 45 is higher than the total of 43.

Answer:

80,000 people will vote. I'm pretty sure

Step-by-step explanation:

You first divided 200,000 by 10 then multiply it by 4 and you get 80,000. You're welcome, if its right.

Answer:

80.000 peple will vote

Step-by-step explanation:

Four out of ten is equivalent to the fraction 4/10 in which when simplified it can be written as 2/5 (I simplified the fraction to make it easier), then you just multiply the fraction by the amount of people =200,000. When multiplied you will get the result 80.000. Hope this helps :)

Answer:

A

Step-by-step explanation:

Given

- 0.6x > 3

Divide both sides by - 0.6, reversing the symbol as a result of dividing by a negative quantity, thus

x < - 5 → A

Answer:

the second one four fifth times 20

Step-by-step explanation:

4/5×22.01=17.68 which is approximately equal with 4/5×20=16.

Its four fifths times 20 i took the test.

Step-by-step explanation:

Sun's money = x

Brittney's money = 2x

x + 2x = $60

3x = $60

3x/3 = 60/3

x = 20

So amount that Brittney has is 2x.

The amount they have together is 3x

The equation that describes the problem is 3x = $60

Answer:

Brittney has twice as much money as Sun. Together, they have $60. Let x represent the amount of money Sun has.

What expression represents the amount of money Brittney has?

✔ 2x

What expression represents the amount of money that Brittney and Sun have together?

✔ 2x + x

What is the equation described in this problem?

✔ 2x + x = 60

Step-by-step explanation:

Answer:60%

Step-by-step explanation:

If there are 1000 students in total and 600 are majoring in engineering, you divide 600 by 1000 to find the percent of students majoring in engineering. (600/1000) =.6

To turn a decimal into a percent you move the decimal over 2 places making it 60%.

Answer: 600/1000 = .6 that is the answer

or 60% when you turn the decimal to percent

The answer for [tex]m[/tex] :

[tex]m = -17[/tex]

Step-by-step explanation:

Solve for [tex]m[/tex] :

[tex]-6 + m = -23[/tex]

Add both sides by 6:

[tex]-6 + 6 + m = -23 + 6[/tex]

[tex]m = -17[/tex]

So, the answer is [tex]x = -17[/tex]

Answer: 45 handshakes.

Step-by-step explanation:

We have 10 kids.

Let's count.

Kid 1, can meet other 9 kids, so here we have 9 handshakes.

Kid 2, he can meet other 9 kids, but he already handshaked kid 1, so here we only count 8 handshakes.

Kid 3, he can meet other 9 kids, but we already counted the handshake with kid 1 and kid 2, so from here we only count 7 handshakes.

You can see the pattern, the total number of handshakes will be:

H = 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1  = 45

Answer:

45 handshakes

Step-by-step explanation:

Answer:692.82 ft

Step-by-step explanation:

Given

Height of tower is [tex]h=100\ ft[/tex]

Tower is mounted at the top of [tex]H=1100\ ft[/tex] hill

angle of elevation [tex]\theta =60^{\circ}[/tex]

Using figure we can write

[tex]\tan \theta =\dfrac{h+H}{\text{Distance}}[/tex]

[tex]\tan 60^{\circ}=\dfrac{100+1100}{\text{Distance}}[/tex]

[tex]Distance =\frac{1200}{\tan 60^{\circ}}[/tex]

[tex]Distance=\frac{1200}{\sqrt{3}}[/tex]

[tex]Distance=692.82\ ft[/tex]

Answer:

x=37

Step-by-step explanation:

Complementary angles add up to 90 degrees.

Let's first find the measure of the complement.

90-32=58

Now we can set the numerical value of it equal to the expression it gave us.

2x-16=58

We have to isolate x.

Lets add 16 to both sides

2x=74

Divide both sides by 2.

x=37

Step-by-step explanation:

Answer:

12 inches long

Step-by-step explanation:

So you have the ratio x : 3x

4x = 48

x = 12

Plug in:

12 * 1 = 12

The length of the shorter piece is 12 inches if the 48​-inch board is cut into two pieces. One piece is three times the length of the other.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

A 48​-inch board is cut into two pieces. One piece is three times the length of the other.

Let x and y be the length.

x = 3y

x + y = 48

3y + y = 48

y = 12 inches

x = 36 inches

Thus, the length of the shorter piece is 12 inches if the 48​-inch board is cut into two pieces. One piece is three times the length of the other.

Answer:

(B)Angle S

Step-by-step explanation:

Given that line segments RS and ST combine to form an angle.

The angle formed by the two line segments occur at the common end point of the two segments which in this case is S.

Therefore the angle is formed at S.

This can be written in the following ways:

[tex]\angle RST, \angle TSR$ or simply \angle S.[/tex]

The correct option is B.

Answer:

Answer:

1/4 = 25%

Step-by-step explanation:

The probability of heads is 1/2.

The probability of an even number on a die is 3/6 = 1/2.

The probability of both is (1/2) (1/2) = 1/4, or 25%.

Answer:

make me brainlist pls pls pls pls

Step-by-step explanation:

A "fair" coin lands heads-up half of the time and "tails-up" half of the time.

For one flip, the probability of landing heads-up is 1/2.

Of those successes, we now consider the probability of the "fair" die landing with an even number on top. This probability is (number of successes) / (total number of possibilities) = 3/6, or 1/2.

So, the probability of both events happening ("and") is 1/2 of 1/2, or (1/2)*(1/2) = 1/4.

Answer:

11) D. 144 b/m

12) B. As exercise levels increase, heart rate increases

13) D. Transporting wastes away from cells

14) B. Capillaries

15) This is because during excercise you increase the skin blood flow in order to enable ¨heat dissipation¨. Then after the increase in blood flow to the muscles decides to have an increase which causes it to have a cardiac output which is in direct proportion to the increase in oxygen consumption.

Answer:Sixth grade

Step-by-step explanation:

Given

There are [tex]840[/tex] sixth grade students out of which [tex]700[/tex] Participated in math olympiad

also no of fifth grade students[tex]=910[/tex]

Fifth graders who participated in math olympiad [tex]=745[/tex]

Since [tex]745>740[/tex]

There are more fifth graders in Olympiad [Numerically]

Percentage wise

Percenteage of sixth graders who participated in Math olympiad[tex]=\dfrac{700}{840}\times 100=83.33\ \%[/tex]

Percenteage of Fifth graders who participated in Math olympiad[tex]=\dfrac{745}{910}\times 100=81.86\ \%[/tex]

So, a greater Population of Sixth graders participated in math olympiad compared to Fifth graders as [tex]83.33\ \%>81.86\ \%[/tex]

Answer:

Perimeter: [tex]p = 4\cdot l[/tex], Total costs: [tex]C = 24\cdot l[/tex]

Step-by-step explanation:

The garden has a square form. Let be [tex]l[/tex] the length of any of the sides, measured in yards. The perimeter of the garden, measured in yards, is:

[tex]p = 4\cdot l[/tex]

Now, perimeter has a length unit and total costs of edging the garden, measured in US dollar, is:

[tex]C = \left(6\,\frac{USD}{yard} \right)\cdot 4\cdot l[/tex]

[tex]C = 24\cdot l[/tex]

Answer:

122 employees

Step-by-step explanation:

So, first you have to find 22% OF 100 WHICH IS 22. (100x0.22= 22) Then, since they have to lay off 22% more people you add the 22% of 100 (22) to the 100. (100+22=122) This means that they have laid off 122 employees this year. I hope this helps!
