Answer:
Step-by-step explanation:
Given
diameter of 41.6 m
So radius =41.6/2= 20.8
Solution
volume of a hemisphere=4/3πr^2
=4/3×3.14×20.8×20.8
=5433.9584/3
=1811.319
So the answer is 1811.319 =1811(nearest 10)

What value of x makes the equation true?
6x+8=3x-19
A. x = 3
B. x = -3
C. x = -9
D. x = -11/3
Correct answer will get brainiest!
Answer:
C
Step-by-step explanation:
Given
6x + 8 = 3x - 19 ( subtract 3x from both sides )
3x + 8 = - 19 ( subtract 8 from both sides )
3x = - 27 ( divide both sides by 3 )
x = - 9 → C

Answer:
Option 3
Step-by-step explanation:
3/2 times x - 3 = y can also be:
y=3/2 times x-3
-3 is the y-intercept. This is one of the points, (0,-3).
Now, you need to solve for x. Say y equals 0.
3/2 times x-3 will equal 0.
3/2 times 2 = 6/2 which equals 3. You can solve the equation now.
3/2 times 2 - 3 = 0
2 is the x-intercept. This is the other point in the line, (2,0).
So the answer is Option 3

Answer:
[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Slope formula is:
[tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1}}[/tex]
Let's plug-in our numbers.
[tex]\frac{12 - 8}{4 - 10} = \frac{4}{-6} = -\frac{4}{6}[/tex]
Now, we must simplify the fraction. We can do this by by finding the GCF (Greatest Common Factor). Let's list out what 6 and 4 have in common.
What can 6 be divided into?
2 * 3 = 6
1 * 6 = 6
What can 4 be divided into?
2 * 2 = 4
1 * 4 = 4
The GCF of these two numbers is 2!
[tex]-\frac{4\div2}{6\div2} = -\frac{2}{3}[/tex]
So, our slope is [tex]-\frac{2}{3}[/tex]
Another way to solve this is [tex]\frac{rise}{run}[/tex]I have shown how to do this in the picture below. We get the same answer solving this way as well.

What is the range of the function on the graph?
Answer:
The range is greater than or equal to -3
Step-by-step explanation:
The range is y.
At y = -6, x doesn't have values.
At y = -3, x stops; therefore, y is greater or equal to -3.
At y = 2, x has values.

Leo took an Uber to get to football practice. Uber charged $1.25 per mile (m) and he gave the driver a $5.00 tip. If the total trip was $16.25, how many miles did he travel to football practice?
Answer:
9milesStep-by-step explanation:
Step one:
given data
we are told that the uber charges $1.25 per mile
and that Leo also gave a tip of $5
the function for the total charge is given as
y=mx+c
Step two:
we will use the notation m for the number of miles traveled
given that the total trip is $16.25
16.25=1.25m+5
solving for m we have
16.25-5=1.25m
11.25=1.25m
divide both sides by 1.25
m=11.25/1.25
m=9
So he travelled 9miles

An object is moving at a speed of 850 miles per hour. Express this speed in meters per minute.
Answer:
it would be 1385
Step-by-step explanation: because 850 miles per hour converted into meter per min would be 22799.04 meters per sec and then u would Find the number in the whole number place 4 and look one place to the right for the rounding digit on the right side of the decimal point 7. Round up if this number is greater than or equal to 5 and round down if it is less than 5
So the answer is 1385
Answer:
22799 meters per minute I don't know how to express
multiply 850 by 26.822 and u should get 22799 well almost
What is 70% of 900
Pls answer quickly
Answer:
630Step-by-step explanation:
10% of 900 is 90 (900÷10)
20% of 900 is 180 (90×2) - basically the 10% times 2
50% of 900 is 450 (900÷2)
450+180=630 - the sum of the 20% and 50%

Answer:
x = 7.5 cm
Step-by-step explanation:
ΔBCA ~ ΔECD ⇒ the corresponding sides are proportional.
[tex]\frac{AC}{DC}[/tex] = [tex]\frac{AB}{DE}[/tex]
AC = 4 + 6 = 10 cm
[tex]\frac{10}{6}[/tex] = [tex]\frac{x+5}{x}[/tex] ⇔ 10x = 6(x + 5) ⇒ x = 7.5 cm

the points. Then use the slope to graph the line.
The slope is
Answer:
Step-by-step explanation:
The slope is the change of y over the change of x.
the change of y:77-22=55
the change of x:49-14=35

if f(x) = 6x, what is f(3)
Answer:
f(x)=18
Step-by-step explanation:
When it gives you f(3), it is basically telling you that you need to plug in 3 for x. Doing so would give you f(3)=6(3) and you can multiply 6 and 3 together to get 18.

how do you find an equation for a line with a slope of 2/3 passing through (1,-4)
Answer:
The standard general equation for a straight line is:
y = mx + C. You said the slope of line is 2/3. m is always the slope in this context. So with the numerical value slope we have the line
Y = 2/3 X + C. You also said the line passes through the point (1, -4) that is the X value is 1 and the y value is -4. Substitute these value into the linear equation to find C, as follows
-4 = 2/3 + c. and so C = - 4 - 2/3 = -14/3 and so the equation of line is :
y = 2x/3 + 14/3 or if you like 3y = 2x + 14
It is important to remember that the convention of the bracketted numbers e.g. (1,-4) or ( 1, -4, z), say is that the first number in the brackets indicates the X value, the second the y value and the third, the z value in the case of 3 D coordinates.
Convert 2x + 37y = 18 to point-slope form.
Answer:
x=−37/2 y+9
Step-by-step explanation:
2x+37y=18
2x+37y+−37y=18+−37y
2x=−37y+18
2x2=−37y+18/2
x=−37/2 y+9
Use the diagram to find the measure of angle KHL.
Answer:
m∠KHL = 43°
Step-by-step explanation:
From the picture attached,
m∠KHL ≅ m∠GHL [Given in the picture]
Now substituting the values of the angles,
(3x + 1) = (5x - 27)
1 + 27 = 5x - 3x
28 = 2x
14 = x
m∠KHL = (3x + 1)° = (3 × 14) + 1
= 42 + 1
= 43°
Therefore, measure of ∠KHL = 43°
