IF YOU ANSWER THIS RIGHT NOW ILL GIVE YOU 64 POINTS
Answer:
13 = x
Step-by-step explanation:
[tex]\frac{6}{8}[/tex] = [tex]\frac{(x + 2)}{(x + 7)}[/tex]
6x + 42 = 8x + 16
42 = 2x + 16
[tex]\frac{26}{2}[/tex] = [tex]\frac{2x}{2}[/tex]

System of equations!!!
Answer:
Step-by-step explanation:
1. x^2-x-20=3x-15
x=5, x=1 substitute
y=3*5-15 = 0
y=3*(-1)-15 = -18
Solution: (5,0) & (-1,-18)
2. x^2+2x+3=x+5
x=-2, x=1 substitute
y= -2+5 = 3
y=1+5 = 6
Solution: (-2,3) & (1,6)

In the diagram, the radius of the outer circle is 2x em and the radius of the inside circle is 6 cm. The area of the shaded region is 220 cm? What is the value of x2
Answer:
Answer: 8 (second choice)
Step-by-step explanation:
Area of a Circle
Given a circle of radius r, the area is calculated by the formula:
[tex]A=\pi\ r^2[/tex]
There are two circles in the diagram. The outer circle has a radius of r1=2x, thus its area is:
[tex]A_1=\pi\ (2x)^2[/tex]
The interior circle has a radius of r2=6 cm, thus its area is:
[tex]A_2=\pi\ 6^2=36\pi[/tex]
The shaded area is obtained by subtracting A1-A2:
[tex]A=\pi\ (2x)^2-36\pi[/tex]
The value of the shaded area is given as 220π cm2. Equating:
[tex]\pi\ (2x)^2-36\pi=220\pi[/tex]
Dividing by π:
[tex](2x)^2-36=220[/tex]
Adding 36:
[tex](2x)^2=220+36=256[/tex]
Taking square root:
[tex]2x=\sqrt{256}=16[/tex]
Dividing by 2:
x = 8 cm
Answer: 8 (second choice)

Jasmine has 50 marbles in a bag. 20% of the marbles are blue. How many marbles are not blue? Explain how you found your answer.
Answer:
20% of 50 marbles is 1 fifth of the marbles in the bag. so 50 marbles divided by 5 =10 blue marbles
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
WOW, that's a lot of points!!
To find the answer for this problem, you take 80% of 50.
In the bag, 20% of the marbles are blue. That means that the rest of the 80% are not blue. So, take 0.8 * 50 = 40. 40 marbles that are not blue.

Karl invests $35,000 for 8 years in an account paying 7% compounded daily. Find
the annual percentage yield (APY) to the nearest hundredth of a percent. *
a.9.38%
b.12.72%
c.10.14%
d.11.36%
Answer:
principal (p)=$35000
time(t)=8years
rate ( r)=7%
Step-by-step explanation:
compounded amount(c.a)=p((1+r/100)^t )=$35000((1+7/100)^8)=$60136.5compound interest gain=$60136.5-$35000=$25136.5Karl gain interest in 1 year=$35000((1+7/100)-1)=$2450gain % in 1 year=$2450/$25136.5×100%=9.74% Two distinct number cubes, one red and one blue, are rolled together. Each number cube has sides numbered 1 through 6. What is the probability that the outcome of the roll is an even sum or a sum that is a multiple of 3?

3. Find the surface area for the given cylinder. Use 3.14 for r and round to the nearest whole number. (1 point)
A. 904
B.1,017
C.1,130
D.2,713
Answer:
C
Step-by-step explanation:
The surface area of a cylinder is given by the formula:
[tex]SA=2\pi rh+2\pi r^2[/tex]
Where h is the height and r is the radius of the cylinder.
The given radius is 6 and the height is 24.
We are also using 3.14 for π.
Therefore;
[tex]SA\approx 2(3.14)(6)(24)+2(3.14)(6)^2[/tex]
Evaluate:
[tex]SA\approx1130.4\approx 1130[/tex]
The answer is C.

One winter day, the temperature was -15 degrees Fahrenheit. Later that day the temperature rose 12 degrees Fahrenheit to reach the high temperature for the day. If t represents the high temperature what is t.
-3
-15 plus 12 is -3
so T= -3
