Write an equation for 96% of what number is 24?
Answer:
0.96 • x = 24, x = 25
Step-by-step explanation:
96% of what number is 24
Let's break this phrase down.
96% can be represented as 96/100 or 0.96
"of" indicates multiplication
"what number" is our unknown variable, x.
"is" represents our equals sign
Then we have our answer 24.
Let's put this all together.
0.96 • x = 24
To solve for this, divide both sides by 0.96.
x = 25
Hope this helps!

What should we find in order to determine how many square feet of plywood are needed to make a rectangular prism
Answer:
surface area
Step-by-step explanation:
A rectangular prism is an optical element which is transparent with flat sides that can pass or reflect light. A rectangular prism is a cube where all its sides are the same.
In the context, in order to find the total square feet of plywood needed to make a prism we have to determine its surface area.
The total surface area of a rectangular prism can be found out by the formula :
A = 2 (hl + lw + wh)
where, h = height of the rectangular prism
l = length of the rectangular prism
w = width of the rectangular prism

Answer:
C) 12.5
The length of BC = 12.5cm
Step-by-step explanation:
Step(i):-
Given that ΔABC
Given that AB = 15cm and ∠A = 40°
we will use trigonometric function
[tex]tan x = \frac{oppositeside}{adjacentside}[/tex]
[tex]tan 40^{0} = \frac{BC}{AB} = \frac{BC}{15}[/tex]
Step(ii):-
we know that tan40° = 0.83909
[tex]tan 40^{0} = \frac{BC}{15}[/tex]
BC = 15 × tan 40°
BC = 12.58649
BC = 12.5cm
Final answer:-
The length of BC = 12.5cm

Consider the equation r + 2 = 3x – 4.
a. Solve the equation using algebra.
X=
Answer:
r/6 +2 = X
Step-by-step explanation:
We want to isolate X by itself to find its value. First transpose your -4 to the other side (note that -4 will become positive)
r + 2 +4 = 3x
r + 6 = 3x
To find the X, we get rid of the 3, so divide both sides by 3
r/3 + 6/3 = x
r/3 + 2 = x
OR
(r+6)/3 = x
Both works : )
Answer:
Step-by-step explanation:
We want to solve r + 2 = 3x – 4 for x.
This means isolating x on one side. To do this, first add 4 to both sides, obtaining r + 2 + 4 =3x, or:
r + 6 = 3x
Finally, divide both sides by 3:
r + 6

Find the slope of the line passing through the points (-4, 2) and (3, 2)
Answer:
0
Step-by-step explanation:
The slope of a line is also known as the change in the line. it is often referred to as ([tex]\frac{rise}{run}[/tex]) and can be found using the formula, ([tex]\frac{y_2-y_1}{x_2-x_1}[/tex]). Substitute in the given points and solve for the slope,

Josephine bought 8 gallons of milk.
How many liters does that equal?
Answer:
Either 30 or 32, depending on if your teacher wants you to use exact decimals, or rounded numbers
Step-by-step explanation:
Usually people round liters to equal 4 per gallon, which would give you 32.
However, a liter is technically 3.785 liters per gallon- and this exact number would give you 30 as an awnser.
I'd say 32 is the safer awnser, unless your teacher has given you the number 3.785 decimal amount to use instead.

Answer:
Step-by-step explanation:
y = 3x + 4
Plugin x = 3 in the equation,
y = 3*3 + 4
= 9 + 4
y = 13
Plugin x = 4 in equation,
y = 3*4 + 4
= 12 + 4
y = 16
Plugin x = 5 in the equation,
y = 3*5 + 4
= 15 + 4
y = 19
2) y =x - 7
Plugin x = 10 in the equation
y = 10 - 7
y = 3
Plugin x = 15 in the equation
y = 15 - 7
y = 8
Plugin x = 20 in the equation
y = 20 - 7
y = 13

please answer , I have no idea how to do this
Using the table, it is found that there is a 77% probability that a seventh grader chosen at random will play an instrument other than bass.
-----------------------------
A probability is the number of desired outcomes divided by the number of total outcomes.The table is given at the end of this question.From the table:
There are 12 + 10 + 9 + 12 = 43 7th grade students.Of those, 33 play an instrument other than the bass.Then:
[tex]p = \frac{33}{43} = 0.77[/tex]
0.77 = 77% probability that a seventh grader chosen at random will play an instrument other than bass.

x²+3xy−18y²
Answer:
(x + 6y)(x - 3y)
Step-by-step explanation:
Given
x² + 3xy - 18y²
Consider the factors of the coefficient of the y² term (- 18) which sum to give the coefficient of the xy- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , then
x² + 3xy - 18y² = (x + 6y)(x - 3y)

Step-by-step explanation:
Alfonso scored 1818 points during his last basketball game, which was 40\%40% of the points the entire team scored. The entire team scored points.
Answer: 45 points
Step-by-step explanation:
Let the point of the entire team be represented by x.
Alfonso scored 18 points during his last basketball game, which was 40% of the points the entire team scored. This can then be represented in an equation as:
40% of x = 18
40% × x = 18
40/100 × x = 18
0.4 × x = 18
0.4x = 18
x = 18/0.4
x = 45
The team's total point is 45
choices;
a) 21.8°
b) 35.2°
c) 45.1°
Answer:
[tex] \displaystyle a) \: {x}^{ \circ} = 21.8 ^{ \circ} [/tex]
Step-by-step explanation:
we are given opposite and adjacent
we want to figure out x°
remember that,

where our opp is 5 and adj is 12.5
let [tex]\theta[/tex] be x°
so
