Answer:
1017 cm³
Step-by-step explanation:
To find the volume of this figure we will first need to divide it into 2 sections. First, we will find the volume of the semicircle on top then the cone at the bottom!
1) Semicircle
The simplest way of doing this is to find the volume as if it was a circle and then divide that result by 2! ([tex]\frac{4}{3}[/tex]πr³)
[tex]\frac{4}{3}[/tex] × 3.14 × 6³ = 904.32904.32 ÷ 2 = 452.162) Cone
To find the volume of the cone we need to apply the equation πr²[tex]\frac{h}{3}[/tex] (where h = height)
3.14 × 6² × [tex]\frac{15}{3}[/tex] = 565.23) Add
452.16 + 565.2 = 1017.361017 rounding to the nearest whole number!Hope this helps, have a lovely day! :)

(22 - 4) / 6
The answer would be 3 miles on each of the six days
Answer:
In a week we have 7 days.
On the first day, Clare runs 4 miles.
On the other six days, she runs the same distance, let's call it D.
In total, she runs 22 miles.
Then:
4mi + 6*D = 22 mi
6*D = 22mi - 4mi = 18mi
D = 18mi/6 = 3mi.
Then the other 6 days, Clare runs 3 miles

The circle graph describes the distribution of preferred music from a sample of 400 randomly selected middle school students.
a circle graph titled preferred music, with five sections labeled rock 13 percent, hip hop 25 percent, pop 35 percent, classical 13 percent, and jazz 14 percent
Which of the following conclusions can we draw from the circle graph?
Pop is the preferred music for 35 students.
Jazz is the preferred music for 56 students.
Together, Hip Hop, Rock, and Jazz are the preferred music for less than half the students.
Together, Hip Hop and Pop are the preferred music for 260 students.
Answers
Answer:
Step-by-step explanation:
(i) Number of people who are into classical music =10%
10% of pie chart =20 people.
1% ⇒ 10/20 ×100
and 100% ⇒ 10/20 ×100 × 100/ 100
⇒200 people.
(ii) Light chart represent maximum number as it is 40% of total. ∴ Light music is liked by maximum people.
(iii)
Number of CD's of classical music ⇒ 100/10 × 1000(10%) =100
umber of CD's of semi classical music = 100/20 × 1000(20%) =200
just like that 30% is 300, 40% is 400.
Hope this helped :)
Triangle ABC is a scale drawing of Triangle XYZ, as shown.
Based on the information shown in these triangles, which of the following is a true statement?
A) The length of side XZ is 11.5.
B) The length of side XZ is 28.
C) The measure of angle A is equal to the measure of angle Z.
D) The measure of angle A is not equal to any of the angle measures of Triangle XYZ.
Answers
Answer: B the side length of XZ is 28
Step-by-step explanation:
to find the scale factor, one of the methods is to divide the side length of one triangle by the same side length of the other triangle.
for example with this problem, the length of XY is 42 while side length AB is 12. 42/12 is 3.5. we know that the side length that corresponds with XZ is 8 so multiply it by 3.5 to get the answer of 28.
Answer:
B
Step-by-step explanation:
Since we know that triangle XYZ is a scale model of ABC then if we find the amount XYZ is bigger then ABC then we can find the answer. Line CB is the corresponding line to ZY and ZY is 3.5x greater then CB. Apply the same logic to AC and we get 8*3.5=ZX 8*3.5=28 so ZX=28.

Haven't done this kinda problem in a while but I got 4/3 cm/s
Step-by-step explanation:
Using the coordinates given i put them into the formula:
y1 - y2
m=_________
x1 - x2
That gave me -16/-12, I simplified & got 4/3.
To find the slope you need at least two points on a line
The formula would be m=y2-y1/x2-x1
16-0/12-0
16/12
Simplified we would divide by 4 since it goes into both numbers
4/3 as the answer
a sample of 500 schools in a state results in an average number of students per grade level of 178.6 students, with a margin of error of 45.2 if there are 3250 high schools in the state, what is the estimated number of students per grade level?
Answers
The margin of error is given as 45.2, which means that we can be 95% confident that the true population average number of students per grade level falls within the range of the sample average plus or minus the margin of error.
So, the confidence interval is:
178.6 ± 45.2
To estimate the population average number of students per grade level, we can take the midpoint of the confidence interval:
(178.6 + (178.6 - 45.2)) / 2 = 311.6
Therefore, the estimated number of students per grade level in the state is 311.6

Bryan randomly asked several students which type of animal they had at home as a pet. The results are in the pie chart below.
a. What percent of the students had dogs?
b. What percent of the students had birds?
c. How many total students did Bryan interview?
Answers
Answer:
60% of the students have dogs
10% of the students have birds
Bryan interviewed 200 students
Step-by-step explanation:
a.3/5 = 60%
b.60% + 30% = 90%
100% - 90% = 10%
c. 20 x 10 = 200
Answer: 60%, 10%, 200 students.
Step-by-step explanation:
Let's start with turning all of the values into percentages.
3/5 of the students said dogs. As a percentage, 3/5 is equal to 60%.
We now have two percentages, the amount of cats and the amount of dogs. 30%+60%=90%. So that leaves 10%, and that 10 percent is the 20 students who had birds.
If 20=10%, all we have to do is multiply 20 ten times to get to 100%. 20x10=200.
There were 200 students interviewed.

The translation used to create the image include the following: A. 5 units down.
What is a translation?In Mathematics and Geometry, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image;
g(x) = f(x + N)
Conversely, the translation a geometric figure downward simply means subtracting a digit from the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) - N.
Based on the information provided, we have:
(x, y) → (x + h, y + k)
(1, -1) → (1, -6).
1 + h = 1
h = 1 - 1
h = 0
-1 + k = -6
k = -6 + 1
k = -5.

Mars has a polar diameter of 6752 kilometers, and the Mars Reconnaissance Orbiter comes as close to the planet as 255 kilometers. How far does MRO travel in one orbit?
Answers
Answer:
MRO’s orbit is near enough to circular
that the formulas for circles can be used.ep-by-step explanation:
The MRO completes one orbit around Mars in about 2.3 hours, and travels a distance of 40,727 km in that time.
What is MRO?The Mars Reconnaissance Orbiter (MRO) is an orbiting spacecraft that was launched in 2005 by NASA. The objective of MRO is to study the climate, geology, and geography of Mars. MRO is currently in a nearly circular polar orbit around Mars, which allows it to observe the entire planet in high resolution. MRO has an orbital altitude of 255 km, and its orbital period is about 2.3 hours.
The circumference is 2πr, where r is the radius of the orbit. The radius of the orbit of MRO is the difference between the polar diameter of Mars and the closest approach of MRO to the planet, which is 6752 km - 255 km = 6507 km.
Thus, the circumference of the orbit of MRO is 2πr = 2π x 6507 km = 40,727 km. Therefore, the MRO travels 40,727 km in one orbit.

Answer: -1/2
Step-by-step explanation:
1. We know that -2 1/3 is also equal to -7/3, because we can multiply the denominator by the main number, and add the numerator.
2. We can do the same with 4 2/3, which would be 14/3.
3. Now, we are left with -7/3 divided by 14/3.
4. To make this easier, we can flip flop the 14/3 so we can multiply instead of divide, which leaves us with -7/3 x 3/14.
5. -7/3 x 3/14 = -21/42
6. We can simplify this to -1/2.
