Answer:
66
Step-by-step explanation:
Answer:
y=66
Step-by-step explanation:
Start with the angle that has the purple arrow pointing to it. Next to it, part of the right angle is 27 degrees so you subtract that from 90 degrees, which makes you get 63 degrees. The measurement of all a triangle's angles is 180 degrees, so you add 63 and 51 to get 114, then subtract 114 from 180 to get 66 degrees.

Answer:
AX : XB as AB : AC
AX = 5
XB = 4
AC = 6
AB = x
Step-by-step explanation:
5 : 4 as to x : 6
ratios can also be written as fractions...
5/4 = x/6 ..now we have a proportion...so we cross multiply
(4)(x) = (5)(6)
4x = 30
x = 30/4

Answer:
a) If the volume of the prism on the left is 1029 m³, then the volume of the prism on the right is 1536 m³.
b) If the height of the prism to the left is 14 m, the height of the prism to the right will be 16 m.
c) If the surface area of the prism to the left is 392 m², the surface area of the prism to the right will be 512 m².
Step-by-step explanation:
a) To solve, set up a proportion. Volume is three-dimensional, so we need to cube.
(7/8)³=1029/x
Now we can solve using cross products to get 1536.
If the volume of the prism on the left is 1029 m³, then the volume of the prism on the right is 1536 m³.
b) To solve the second one, we also set up a proportion. Height is one-dimensional, so we will not need exponents here.
7/8=14/x
Solve using cross products to get 16.
If the height of the prism to the left is 14 m, the height of the prism to the right will be 16 m.
c) Now we are solving for area, which is two-dimensional. Therefore, we will need to square.
7/8²=392/x
Solve using cross products to get 512.
If the surface area of the prism to the left is 392 m², the surface area of the prism to the right will be 512 m².

Answer:
128 shirts will be green
Step-by-step explanation:
About 32% of the shirts were green from the sample of 300. so if you take 32% of 400, you get 128.
Two friends plant a tree and record the height of the tree each following year to track its growth. The data can be represented by the linear model y = 4.3z +3.25, where y represents the height of the tree, in feet, and z represents the number of years since it was planted.
Based on the linear model, what is the expected height of the tree in 8 years?
3.25
4.3
31.2
37.65
Answer:
D.) 37.65
Step-by-step explanation:
I know that 8 is an input based on this word problem. So, then I plug in the 8 for z and solve to find the expected height of the tree in 8 years.
y=4.3z+3.25
y=4.3(8)+3.25
y=34.4+3.25
y=37.65
In 8 years the expected height of the tree is 37.65

Answer:
Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units

Compare the data and use the correct measure of center to determine which team typically has the tallest players. Explain your answer.
The Allstars, with a mean of about 67.1 inches
The Champs, with a mean of about 66.4 inches
The Allstars, with a median of about 68 inches
The Champs, with a median of about 67 inches
Answer:
45
Step-by-step explanation:
The Allstars team has the higher mean and median compared to Champs team. Therefore, the Allstars has the tallest players.
Using Mean and Median to Decide the Tallest TeamBy using mean and median, we can know which team typically has the tallest players
For the Allstars:
Mean: The mean height of the Allstars team is obtained by summing up all the heights and dividing by the total number of players:
Mean = (73 + 62 + 60 + 63 + 72 + 65 + 69 + 68 + 71 + 66 + 70 + 67 + 60 + 70 + 71) / 15 ≈ 67.1 inches
Median: The median height of the Allstars team is the middle value when the heights are arranged in ascending order:
Arranging the heights in ascending order: 60, 60, 62, 63, 65, 66, 67, 68, 69, 70, 70, 71, 71, 72, 73
Median = 68 inches
For the Champs:
Mean: The mean height of the Champs team is obtained by summing up all the heights and dividing by the total number of players:
Mean = (62 + 69 + 65 + 68 + 60 + 70 + 70 + 58 + 67 + 66 + 75 + 70 + 69 + 67 + 60) / 15 ≈ 66.4 inches
Median: The median height of the Champs team is the middle value when the heights are arranged in ascending order:
Arranging the heights in ascending order: 58, 60, 60, 62, 65, 66, 67, 67, 68, 69, 69, 70, 70, 70, 75
Median = 67 inches
The Allstars team typically has the tallest players. The mean height of the Allstars team is about 67.1 inches, while the mean height of the Champs team is about 66.4 inches. Additionally, the median height of the Allstars team is about 68 inches, while the median height of the Champs team is about 67 inches. Both the mean and median heights of the Allstars team are higher, indicating that, on average, the Allstars team has taller players compared to the Champs team.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

feet long and 10
feet wide. So far, her mural covers 20%
of the wall. She will paint the remaining part of the wall over the next four days. She will paint the same amount of the wall on each of those four days.
How much of the wall, in square feet, will Julie paint on each of the next four days?
Enter your answer in the space provided.
the wall she's using for the mural is (20.5)(10) = 205 ft², so far she has done 20% of that, well, she still has 100% - 20% = 80% to go on the next four days, so on the next four days she'll be doing 80% of 205 ft².

pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:
•₁ same side interior angles
•₂ m∠1 = 78°, m∠2 = 102°
•₃ oars are parallel, conversed the same side interior angles theorem
Step-by-step explanation:
•₁
The edge of the kayak is a transversal of lines created by oars. The angles are on the same side of transversal and between the oar-lines (inside the area between lines) so they are same side interior angles (or: consecutive interior angles)
•₂
x = 10
m∠1 = 6x + 18 = 6•10 + 18 = 78
m∠2 = 9x + 12 = 9•10 + 12 = 102
•₃
The measures of angles 1 and 2 add to 180° (102+78=180) so they are suplementary angles. It means the oar-lines are parallel.
Based on:
Conversed the Same Side Interior Angles Theorem: If two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.

Frank finds 9 coins on the floor of his car, and 3 of them are quarters. If he finds 15 more coins on the ground, at the same ratio as the coins found in the car, how many more coins will most likely be quarters?
Answer: 5 coins
Step-by-step explanation:
Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or \(\frac{3}{9}\), were quarters.
Simplifying this fraction, we get \(\frac{1}{3}\) of the coins found in the car were quarters.
If Frank finds 15 more coins on the ground at the same ratio, then \(\bold{\frac{1}{3}}\) of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find \(\bold{\frac{1}{3}}\) of 15:
\(\large \frac{1}{3} \times 15 = 5\)
Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.
