Find the length of the radius of the circle.
a. r = 3 d. r = 5
b. r = 4 e. r = 6
c. r = 4.5
Answer:
D) r=5
Step-by-step explanation:
Any triangle formed with one side of the triangle being the diameter of the circle it’s inscribed in will be a right triangle.
6²+8²=c²
36+64=c²
100=c²
√100=c
c=10
So the diameter is 10. That makes the radius 5.
The area of the triangle below is 23.4 square inches. What is the length of the base?

Bianca bought a pack of rechargeable batteries for
$9.99. If the sales tax on the batteries is 3% and Bianca
pays with $11 cash, how much change will she get back?
Answer:
$0.71
Step-by-step explanation:
Find the cost with sales tax
9.99(1.03)
= 10.29
Subtract this from 11
11 - 10.29
= 0.71
So, Bianca will get $0.71 back in change
Answer: 0.71 cents
Step-by-step explanation:
9.99x0.03=0.2997
9.99+0.2997=10.2897 rounds to 10.29
11-10.29=0.71
What is the measure of each angle of a regular 26-gon?
Answer:
Angle of Regular polygon = 166.15° (Approx.)
Step-by-step explanation:
Given:
Regular polygon with 26 sides
Find:
Measure of each angle of Regular polygon
Computation:
Angle of Regular polygon = [(n-2)180] / n
where n = number of sides
Angle of Regular polygon = [(26-2)180] / 26
Angle of Regular polygon = [(24)180] / 26
Angle of Regular polygon = [4,320] / 26
Angle of Regular polygon = 166.15° (Approx.)
Find the midpoint between the following two points
(5, 10), (25, 8)
Answer:
(15,9)
Step-by-step explanation:
let [tex]x_{1}=5, x_{2}=25, y_{1}=10, y_{2}=8\\[/tex]
where the formula of the midpoint is ([tex]\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2}[/tex])
so, ((5+25)/2, (10+8)/2)
Thus, (15,9)

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.y=69(0.92)
x
9514 1404 393
Answer:
decay; 8% decrease per time period
Step-by-step explanation:
The growth factor is the base of the exponential term. The growth rate is 1 less.
growth rate = 0.92 -1 = -0.08 = -8%
When the growth rate is negative, it is exponential decay withe the amount of decrease equal to the magnitude of the rate.
A growth rate of -8% represents exponential decay, with a decrease of 8% per time period.

Answer:
3.13π
Step-by-step explanation:
One plane is a quarter of a semi-circle, since the semi-circle is split into four equal parts. One quarter of a semicircle is one eighth of a circle, so find the are of a circle with diameter 10ft, and divide by 8:
Diameter is half the radius, so the radius is 5ft.
Area of a circle = π(radius)²
=5²π
=25π.
We're looking for an eigth of the circles area so: 25π/8 = 3.125π≈3.13π

Stephanie puts 30 cubes in a box. The cubes are 1 inch on each side. The box holds 2 layers with 15 cubes in each layer. What is the volume of the box?
Step-by-step explanation:
Dimensions of cube = 1 in × 1in .
No. of cubes in each layer = 15 .
No. of layers = 2 .
• Therefore the volume of one cube :-
[tex]\tt \to Volume_{(cube)}= side^3 = (1 \ in.)^3 = \red{1in.^3}[/tex]
• Therefore the volume of one layer :-
[tex]\tt\to 1\ in.^3\times 15 =\orange{15\ in.^3} [/tex]
• Therefore the volume of whole box :-
[tex]\tt\to 2\ in.^3\times 15 =\orange{30\ in.^3} [/tex]
Therefore our required answer is 30 inch ³.
15x2=30 polegadas

A savings account starts with $231 25. After 8 years of continuous compounding at an
interest rate the account has $1850.
What is the interest rate percentage?
Round the answer to the nearest hundredth.
Enter your answer in the box
Answer:
87.5%
Step-by-step explanation:
Took the k12 math test
A savings account starts with $231 25. After 8 years of continuous compounding at an interest rate of 87.5% the account has $1850.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest = P(1+r/n)^rt
A savings account starts with $231 25. After 8 years of continuous compounding at an interest rate the account has $1850.
Compound Interest = P(1+r/n)^rt
[tex]\rm 1850 = 231 25 (1 + r/12)^{96}[/tex]
[tex]\rm 1850 = 231 25 (1 + r/12)^{96}\\\rm 1850 /231 25 = (1 + r/12)^{96}[/tex]
r = 87.5%
Thus, the interest rate percentage is 0.87 rate per year.

Emily plants a rosemary bush that starts at 5
centimeters in height and grows 3 centimeters
per year. How high will the rosemary be after a
certain number of years?
y = [?]x +
Answer:
y(x) = 3x + 5
Step-by-step explanation:
Since the rosemary grows by the same number of centimeters each year, this situation is modeled by a linear function.
Height starts at 5 meters and grows 3 centimeters per year.
This means that the height after a certain number of years, represented by x, is given by:
y(x) = 3x + 5

You roll a pair of six-sided number cubes, numbered 1 through 6. What is the probability of rolling two odd numbers? (Enter your probability as a fraction
Answer:
1/4 or 25%
Step-by-step explanation:
The probability for rolling an odd number is 50% or [tex]\frac{1}{2}[/tex] because there are 3 odd numbers, (1, 3, 5) and 6 total outcomes (1, 2, 3, 4, 5, 6). [tex]\frac{3}{6} =\frac{1}{2}[/tex]
The probability for rolling two odd numbers in a row is
[tex]\frac{1}{2} *\frac{1}{2} =\frac{1}{4}[/tex]
So, the probability of rolling an odd number twice is 25% or [tex]\frac{1}{4}[/tex].

6>w/-2 solve the inequalities
Answer:
w>-12
Step-by-step explanation:
6>w/-2 (Given)
6>-w/2 (Rewrite)
12>-w (Multiply both sides by 2)
-12<w (Remember to flip the sign when dividing or mulitplying by a negative)
w>-12 (Rewrite with w in front)
Therefore, w>-12 is the solution to the inequality.
Answer:
w>-12
Step-by-step explanation:
First, you you need to get rid of the -2 in w/-2 by multiplying -2 by both sides like this.
(-2)6>w/-2(-2)
Then you simplify it like this:
-12>w
However, since you multiplied/divided with a negative, you switch the inequality sign like this:
w>-12
And that's the answer!
