what dose this equal 2(5x + 9) = 48
Answers
Explanation=
2•5x = 10x
2•9= 18
48-18=30
10x=30
Divide each side by 10
x=3
2(5x + 9) = 48
10x + 18 = 48
10x = 48 - 18
10x = 30
x = 30/10
x = 3
What is the value of r?
r= 4 ft
r= 8 ft
r = 16 ft
r = 32 ft
Answers
R=8ft
Step-by-step explanation:
Calculate r using the given formula
r = , with Area = 64π
r = ← cancel π on numerator/ denominator
r = = 8
The required value of radius of circle r is 8 ft
From Figure the area of circle is = 64π, we have to find the radius of the circle.
What is area of circle?Area of the circle is = π[tex]r^2[/tex]
since
the area of the circle is given = 64π
And,
Radius = √area/π
radius= √64π/π
Radius = √64
Radius = 8 ft
Thus The required value of radius of circle r is 8 ft.

what is the measure of x if angle 6 equals 4x and angle 7 equals 2x + 34
112°
64°
17°
68°
Answers
Answer:
17°
Step-by-step explanation:
6 = 4x
7 = 2x + 34
4x - 2x = 2x
Since 6 and 7 are vertically opposite angles, they have the same angle.
2x = 34
X = 34 ÷ 2 = 17
Step-by-step explanation:
< 6 and < 7 are vertically opposite angles so.
< 6 = < 7
4x = 2x + 34°
4x - 2x = 34°
2x = 34°
x = 17°

Mary has $6,000 saved for her college education. She invested that money at 2.3% interest per year. Suppose her account earned interest compounded annually. How much interest would she earn in 3 years?
Answers
Answer:
Interest= $423.59
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $6,000
Number of periods (n)= 3 years
Interest rate (i)= 2.3% = 0.023
To calculate the Future Value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 6,000*(1.023^3)
FV= $6,423.59
Now, the interest earned:
Interest= 6,423.59 - 6,000
Interest= $423.59

Students in a health class are tracking how much water they consume each day. Victoria has two reusable water bottles: a small one and a large one. Yesterday, she drank 3 small bottles and 4 large bottles, for a total of 3,312 grams. The day before, she drank 2 small bottles and 4 large bottles, for a total of 2,888 grams. How much does each bottle hold?
please help
Answers
Given :
Let, capacity of small bottle is x and large bottle is y.
To Find :
How much does each bottle hold ?
Solution :
For condition 1 :
3x + 4y = 3312 ...1)
For condition 2 :
2x + 4y = 2888 ...2)
Subtracting equation 2) from equation 1), we get :
x = 424
Putting value of x in equation 1) is :
[tex]y = \dfrac{2888 - (2\times 424)}{4}\\\\y = 510[/tex]
Therefore, capacity of small bottle is 424 gram and large bottle is 510 gram.
