Write the fraction or mixed number as a percent.
1 4/5
Answer:
180%
Step-by-step explanation:
well 1 = 100%.
4/5 can get up to 100 if you multiply by 20/20. so 4/5 x 20/20 is 80/100 or 80%
100% + 80% is 180%

The product of 3 and
increased by 5
Answer AND expaination
The product of a number and 3 increased by 5 is 7 less than twice the number which equation can be used to find this number , n?
its -7
the product of a number and 3: 3n
increased by 5: + 5
7 less than: - 7
twice the number: 2n
That gives us the following:
3n + 5 = 2n - 7
You only asked for the equation, not to actually help you solve for n, for note. If you do, just subtract 2n from both sides, and then subtract 5 from both sides.

Given:
Event A : the card has the number 8
Event B : the card is blue
The probability of each events are given as:
P (A) = 1/10
P (B) = 1/4
P(A and B) = 1/10 x 1/4 = 1/40
From thea above information, we can see that the outcome of the event A cannot affect the outcome of the event B.
Therefore, the two events are independent.

Answer:
CD = 15
x = 5
Step-by-step explanation:
Since BF ≅ FD and AE ≅ EC, then [tex]EF = \frac{AB + CD}{2}[/tex]
So, [tex]30 = \frac{x^{2} +20 + x^{2} + 22x - 120}{2}[/tex]
[tex]60 = 2x^{2} + 22x - 100[/tex]
[tex]2x^{2} + 22x - 160 = 0[/tex]
[tex]2(x^{2} + 11x - 80) = 0[/tex]
2(x - 5)(x + 16) = 0
x = 5 or x = -16
If x = 5, then CD = [tex]5^{2} +22(5) - 120 = 25 + 110 - 120 = 15[/tex]
Ix x = -16, then CD = will be a negative number which it cannot be.

Sarah works for a maximum of 40 hours per week. She needs to make at least $400 in order to cover her expenses. Her office job pays
$12 per hour and her babysitting job pays $10 per hour.
Which system of inequalities can be used to determine the number of hours she should spend working in office (x) and the number of
hours she should spend babysitting (/) to cover her expenses?
Answer:
x + y ≤ 40
10x + 12 y ≥ 400
x ≥ 0
y ≥ 0
Step-by-step explanation:
System of Inequalities
In order to model the situation stated in the problem, we'll call the following variables:
x = number of hours Sarah spends in the office
y = number of hours Sarah spends babysitting
She works for a maximum of 40 hours per week. This condition leads us to the inequality:
x + y ≤ 40
Her office job pays $12 per hour and her babysitting job pays $10 per hour.
She needs to make at least $400 per week in order to cover her expenses, thus:
10x + 12 y ≥ 400
Two obvious conditions could be added to the set of inequalities:
x ≥ 0
y ≥ 0
The system of inequalities is:
x + y ≤ 40
10x + 12 y ≥ 400
x ≥ 0
y ≥ 0

3 x^2y
3 x^3y^2
Answer:
h= 216x^3y^2÷(8yx9X) = 3x^2y

Answer:
The area of a rectangle is l x w. So the area of the square is 10 x 10 = 100
The area of a circle is
[tex]\pi \times {r}^{2} [/tex]
The radius of all the circles is 2 inches.
[tex]\pi \times {2}^{2} = \pi \times 4 \: or \: 4\pi[/tex]
There are 4 circles so the area of all four is
[tex]4 \times (4\pi) \: or \: 16\pi[/tex]
To find the area of the shaded part of the square, subtract the area of all the circles, because they are not shaded, from the area of the square, because it is shaded. The difference will be the area of the shaded portion.
[tex]area \: = 100 - 16\pi[/tex]
[tex]area = 100 - 50.6548[/tex]
So the area is approximately 50 Sq in

Answer:
66.44 MinutesStep-by-step explanation:
The number of Bacteria, B(t) at any time t(in minutes) is given by the function:
We want to determine the time(in minutes) for the culture to achieve 10,000 bacteria.
Therefore:
Divide both sides by 100

The graph below shows f(x), which represents a parent function, and g(x), which represents a translation of that function.
On a coordinate plane, 2 exponential functions are shown. f (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1. It goes through (negative 3, 8) and crosses the y-axis at (0, 0.5). g (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1. It goes crosses the y-axis at (0, 14) and goes through (1, 5) and (2, 2).
Which statements about the functions are true? Check all that apply.
f(x) = (one-half) Superscript x
g(x) = (one-half) Superscript x + 4 – 2
The ranges of both functions are the same.
The domains of both functions are the same.
The translation from f(x) to g(x) is right 4 units and down 2 units.
Answer:
A. f(x) = (one-half) Superscript x
D. The domains of both functions are the same.
E. The translation from f(x) to g(x) is right 4 units and down 2 units.
The answers are A, D, and E
Step-by-step explanation:
Edge 2020
The statements about the functions are true A. [tex]f(x) = (1/2)^x[/tex]
D. The domains of both functions are the same.
E. The translation from f(x) to g(x) is right 4 units and down 2 units.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).
We are given that On a coordinate plane, 2 exponential functions are shown. f (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1.
When evaluated in zero we have:
f(0) = 2(1/2)^0 = 2
So it crosses through the point (0, 2).
And when evaluated in x = 1, then
f(1) = 2(1/2)^1 = 1
Then it also passes through (1, 1). It goes crosses the y-axis at (0, 14) and goes through (1, 5) and (2, 2).
The answers are A, D, and E
