Answer:
a) (-25)(4)
Step-by-step explanation:
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations. In this case,
withdrew means no longer there which means subtracted.
Then, times mean multiply.
Therefore, -minus twenty-five times (x) four
combine them and it equals (-25)(4)

The table of values shows the height of a buoy compared to the sea floor over time as the tide goes in and out. This can be modeled by a sinusoidal function.
Which statements are true?
Select EACH correct answer
The maximum value of the function is 5.8
The amplitude of the function is 5.8
The period of the function is 24
The frequency of the function is 24
Answer:
1st statement is true
2nd is false (amplitude is (max - min) ÷ 2 so (5.8 - 4.6) ÷ 2 = 0.6)
3rd is true
4th is false (frequency is the reciprocal of period, they can't be the same)

A cylinder has a radius of 2x + 3 and height of 3x + 2. Which polynomial in standard form best describes the total volume of the cylinder? Use the formula V= πr^2h for the volume of a cylinder.
Answer:
[tex]v = \pi {r}^{2} h \\ v = \pi {(2x + 3)}^{2} (3x + 2) \\ v = \pi(4 {x}^{2} + 12x + 9)(3x + 2) \\ v =( 12 {x}^{3} + 36 {x}^{2} + 27x + 8 {x}^{2} + 24x + 18)\pi \\ v =( 12 {x}^{3} + 44 {x}^{2} + 51x + 18)\pi[/tex]
A spinner is divided into an unknown number of equal-sized sections. Your friend spins it 100 times and tells you that it landed on section one 25 times. What is the best estimate of the number of sections the spinner is divided into? 4 25 100 400
Answer:
4
Step-by-step explanation:
the more sections there are the less of a chance the same section ould be landed on so many times. Its almost impossible to land on one of 400 25 times

Find the value of x.
Answer:
x = 29°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180° for x
x = 180° - (128 + 23)° = 180° - 151° = 29°
HELP!! I can't fail. 4 and 5 please!
Answer:
4) x = -3 or 8
Step-by-step explanation:
We factories each algebraic expression
4) x² -5x - 24 = 0
x² - 8x + 3x - 24 = 0
(x² - 8x) + (3x - 24) = 0
x(x - 8) + 3(x - 8) = 0
(x + 3)(x - 8) = 0
x + 3 = 0, x = -3
x - 8 = 0, x = 8
x = -3 or 8

Please help! Describe how the variables in the given equation are related.[tex]p=\frac{kqrt}{s}[/tex]
9514 1404 393
Answer:
p is proportional to q, r, t, and inversely proportional to s
Step-by-step explanation:
Assuming k is a "constant of proportionality," the value of p is directly proportional to each of the numerator variables: q, r, t. P is inversely proportional to the denominator variable, s.

The front of the home is being painted, not including the door the door measures 9ft by 2ft how many square feet will be needed
IGNORE THE WRITING
Answer:
ANSWER BELOW
Step-by-step explanation:
If the door is 9 x 2 ft (18 sq ft):
12 x 18 = 216 sq ft. (Front face including the door)
216 sq ft - 18 sq ft = 198 (Front face not including the roof or door)
For the roof, the formula is h b/2:
So if the height is 4 and the base is 18, the area of the roof is 36.
To find the total area, you must add the area of the front face and the roof (without the door).
198 + 36 = 234 sq ft

Answer:
97 oz.
Step-by-step explanation:
1 lb.=16oz
3+2 lbs = 5 lb's which equals to 80 oz.
then add the extra ounces 7+10 = 17
80 + 17 = 97 oz.
Answer:
D.
Step-by-step explanation:
There are 16 ounces in one pound.
3 X 16 = 48 + 7 = 55 ounces for the first book.
2 X 16 = 32 + 10 = 42 ounces for the second book.
55 + 42 = 97 ounces.

Describe how the graph of y=lxl – 7 is like the graph of y=lxl and how it is different.
Answer:
y = |x| is a parent function
y = |x| - 7 is a translation of the parent function vertically by 7 points down
The shape is same, just the entire graph has shifted down.
It's translated edition of parent function y=|x|
y=|x|If we translate it 7units down then the function is
y=|x|-7So
Everything is same
Just the graph shifted 7units downwards
Find the area of the composite figure to the nearest hundredth.
Answer:
745.31
Step-by-step explanation:
1. 12.5^2 * 2 = 312.5
2. (3,14 * 156,25)/2 = 245.31
3. (30 * 12.5)/2 = 187.5
4. 187.5 + 245.31 + 312.5 = 745.31
Answer:
[tex]745.45 mm^{2}[/tex]
Step-by-step explanation:
(semicircle) A1 = 245.45 mm
(rectangle) A2 = 312.5 mm
(triangle) A3 = 187.5 mm
Formula for semicircle = [tex]A = \frac{1}{2} \pi r^{2}[/tex]
[tex]\frac{1}{2}\pi 12.5^{2} = 78.13\pi = 245.45 mm[/tex]
Formula for rectangle = [tex]A = lw[/tex]
[tex]25 x 12.5 = 312.5 mm[/tex]
Formula for triangle = [tex]A = \frac{1}{2} bh[/tex]
[tex]\frac{1}{2} 30(12.5) = 187.50mm[/tex]
Now we add them all up to get our answer
[tex]245.45 + 312.5 + 187.5 =745.45mm^{2}[/tex]
Substitution
1.y=-5x-19
y=-6x-24
2.y=-6x-22
y=-3x-10
Answer:
1. y=5 and x=-5
2. y=2 and x=-4
Step-by-step explanation:
1.y=-5x-19
y=-6x-24
since both equations are equal to y, they are also equal to eachother
-5x-19=-6x-24
addition P.O.E.
x-19=-24
addition P.O.E.
x=-5
substitute x into one equation
y=-5*-5-19
y=6
2. y=-6x-22
y=-3x-10
since both equations are equal to y, they are also equal to eachother
-6x-22=-3x-10
addition P.O.E.
-22=3x-10
addition P.O.E.
-12=3x
division P.O.E.
-4=x
substitute x into one equation
y=-3*-4-10
y=2
John is on the swim team. Each day he swims 850 m. How far does he swim in 5 days?
Write your answer in kilometers.
help.
Answer:
4.25 km
Step-by-step explanation:
850 x 5 = 4250m
1m = 0.001 km
4250(0.001) = 4.25 km
Answer:
4.25 km
Step-by-step explanation:
850 m × 5 days = 4,250 m
there are 1000 m in a km.
4250 m ÷ 1000 = 4.25 km
express 1 cm3 in m3 please help
Answer:
1E-6 m^3 or 0.000001 m^3
Step-by-step explanation:
1cm^3 = 1cm*1cm*1cm
1m^3 = 100cm*100cm*100cm = 1000000 cm^3
1/1000000 = 1E-6 m^3
