Answer:
20165
Step-by-step explanation:
Given:
Length/height (h) of cylindrical test tube = 152 mm
Radius of cylindrical test tube = 6.5 mm
Volume = [tex] \pi r^2h [/tex]
Required:
Volume of cylinder to nearest whole number
Solution:
The volume is given as [tex] V = \pi r^2h [/tex]
Take π as 3.14 and plug the values of r and h into the volume formula.
[tex] V = 3.14*6.5^2*152 [/tex]
[tex] V = 3.14*6.5*152 = 20165.08 [/tex]
Volume of the test tube = 20165 mm³ (nearest whole number)

In school ,there are 3 girls for every 2 boys . There are 650 students in total . How many students are girls ?
Answer:
Girls = 390
Step-by-step explanation:
Set up a proportion:
In a sample of 3:2, you have 5 kids in all.
So the the ratio of girls to kids in a sample of 5 is 2:5.
So set up a proportion:
(3/5) = (x/650)
5x = 650(3)
5x = 1950
x = 390
Answer:
390Step-by-step explanation:
Let number of boys be b and girls be g. Then we have:
g/b = 3/2g + b = 650From the first equation b is:
b = 2g/3Substitute b in the second equation
g + 2g/3 = 6505g/3 = 650g = 650*3/5g = 390A movie ticket costs $9.A concert ticket costs $45. Which equation can be used to find how many times as much the concert ticket costs than a movie ticket?

Step-by-step explanation:
Numbers are categorized various ways. Some categories include ...
prime, composite
real, complex
integer, rational, irrational
whole number, natural number
positive, negative, zero
algebraic, non-algebraic*
√23 is the positive, real, irrational root of a prime number. It is an algebraic number.
_____
* An algebraic number is a root of a polynomial with integer coefficients.

10
10-8
10
a. The two graphs are the same.
b. The graphs have the same y-intercept. The second graph is steeper than y = |xl.
C. The graphs have the same shape. The y-intercept of y = x is 0 and the x-intercept of the
second graph is 11.
d. The graphs have the same shape. The y-intercept of y = x is 0 and the y-intercept of the
second graph is 11.
How do you solve 2(x-6)=x-14
Answer:
x = -2
Step-by-step explanation:
[2(x-6) = x - 14]
Multiply 2 by x and (-6) in parenthesis, distribution
[2x -12 = x - 14]
Add 12 to both sides
[2x = x - 2]
Subtract x from both sides
[x = -2]

an exponential function is graphed on the grid
based on the graph, which statement about the function is true
a) the domain is the set of all real numbers
b) the domain is the set of all real numbers less than 3
c) the range is the set of all real numbers greater than or equal to 0
d) the range is the set of all real numbers greater than or equal to -9
Answer:
a) the domain is the set of all real numbers
Step-by-step explanation:
Given:
An exponential function and its graph.
A line parallel to [tex]x[/tex] axis is drawn at [tex]y=-9[/tex] which is a dashed line.
Dashed line means, the function does not attain a value equal to [tex]y=-9[/tex].
Domain of a function, [tex]y=f(x)[/tex] is the set of values which can be possible for the variable [tex]x[/tex] that can be given as input.
Range of a function, [tex]y=f(x)[/tex] is the set of possible values of [tex]y[/tex] i.e. the output of the function.
As seen from the graph, the domain of the exponential function does not have any constraint on it.
Therefore, any real number can be given as input.
So, a) The domain is the set of all real numbers.
Let us discuss about the range of function.
As stated above as well, the range of the function can not contain the value [tex]y=-9[/tex].
And there is no value possible below it.
So, the range is all real numbers greater than -9.
The answer is:
"a) the domain is the set of all real numbers" is true.

find the value of x- I WILL GIVE BRAINLIEST!
show work
Answer:
10°
Step-by-step explanation:
It's a right angle so
90° - 52° = 38°
38 - 8 = 30
30 ÷ 3 = 10
check the work
3 × 10 = 30
30 + 8 = 38
38 + 52 = 90
1. A movie theater sells tickets for $9.00 each. Senior citizens receive a discount of $3.00. One evening the theater
sold 636 tickets and took in $4974 in revenue. How many tickets were sold to senior citizens?
Answer:
250
Step-by-step explanation:
x is adult tix, y is senior tix
9x + 6y = $4974
x+y= 636
x=636-y
9(636-y) +6y = 4974
5724 - 9y + 6y = 4974
-3y = 4974-5724
-3y=-750
y=250

Step-by-step explanation:
What is an equation of the line that passes through the point (5, 4) and is parallel to
the line 6x – 5y = 15?
Answer:
6x - 5y does not change as it is parallel so I put x = 5 & y = 4 in this equation and the result is 6 × 5 - 5 × 4 = 30 - 20 = 10 so the parallel equation is 6x - 5y = 10

Somebody has P paintings in his art collection he and other local pain in collectors agreed to donate a total of 48 paintings to the local museum each of the 12 collectors will donate the same number of paintings how many paying's will that person have in his artwork collection after his donation write your answer is an expression expression
Answer:
The person will have P-4 paintings left
Step-by-step explanation:
We are told that the total number of painters who entered into the painting donation agreement to the local museum is 12 painters
and they all agreed to donate 48 paintings equally
so each painter will donate
48/12= 4paintings
Since this person already had P paintings in his art collection
his painting will reduce by the 4 paintings he denoted to the local museum\
hence he will have
P-4 paintings remaining

1) Point P has the coordinates (5,7) what is the image of P' after a 90-degree Rotation? 2) Point P has the coordinates (5,7) what is the image of P' after a 180-degree Rotation? 3) Point P has the coordinates (5,7) what is the image of P' after a 270-degree Rotation? 4) Point A has the coordinates (-5,7) what is the image of A' after a 90-degree Rotation? 5) Point Q has the coordinates (5,7) what is the image of Q' after a 270-degree Rotation? 6) L' (6,-7) is the image of L after a 180 rotation what are the original coordinates L 7) The point A (-5,-8) is first translated 6 units to the right and two units down to get A'.A' is then reflected in the y=-x line to get A''.A'' is then rotated counterclockwise around the origin 270 degrees to get A'''.What are the coordinates of A'''?
Answer:
1) The coordinates of P' is (7, -5)
2) The coordinates of P' is (-5, -7)
3) The coordinates of P' is (-7, 5)
4) The coordinates of A' is (7, 5);
5) Q' is (-7, 5)
6) The coordinates of L is (-6, 7)
7) The coordinates of A''' is (1, 10)
Step-by-step explanation:
1) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)
Therefore, given that the preimage P is (5, 7), we have the image, P', after 90 degrees clockwise rotation is (7, -5);
2) The coordinates of a preimage (x, y) after 180-degrees clockwise rotation gives the image (-x, -y)
Given that the preimage, point P, has coordinates (5, 7) the image, P', after 180-degrees rotation becomes (-5, -7)
3) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)
∴ The coordinates of the preimage, P = (5, 7), after 270-degrees clockwise rotation gives the image, P', = (-7, 5)
4) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)
Therefore, given that the preimage A is (-5, 7), we have the image, A', after 90 degrees clockwise rotation is (7, 5);
5) The coordinate of the preimage, point Q is (5, 7) after 270-degrees clockwise rotation gives the image, Q', = (-7, 5)
6) The image of a preimage, (x, y) after 180-degrees rotation is (-x, -y). Therefore, given that the image of the preimage L, after 180 degrees rotation is L' (6, -7), we have the coordinates of L is (-6, 7)
7) The coordinates of the preimage, A = (-5, -8)
a) A is translated 6 units to the right and 2 units to give;
A'(-5 + 6, -8 - 2) = A'*1, -10)
b) (x, y) is reflected across the line y = -x, to give (-y, -x)
∴ A'(1, -10) is reflected across the line y = -x, A''(10, -1)
c) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)
∴ The coordinates of the preimage, A''(10, -1), after 270-degrees clockwise rotation gives the image, A'''(1, 10).
Suppose you deposit $275.00 in your savings account on December 31. Your bank pays 3 percent annual interest on savings accounts. If you do not deposit any more money into the account, what would be the balance on December 31 of the following year?
Answer:
275 * 0.03 = accrued interest
accrued interest + initial deposit = total after one year
Step-by-step explanation:
Tulip bulbs are on sale at store A, at 5 for $11.00, and the regular price at store B is 6 for $13. Is each store pricing tulip bulbs at the same rate? Explain how you know.
Answer:
No, they are not sold at the same rate
Step-by-step explanation:
An easy way to figure situations like these can be taking the number of items there and then dividing by the total price. For A, each bulb costs $2.2, for B each bulb costs $2.1666.
11/5=2.2
13/6=2.1666
