Answer:
r = 3.7 cm
Step-by-step explanation:
19.02 = 1/2π(2radius) + diameter
expanding:
19.02 = 1/2(3.14)(2r) + 2r
19.02 = 3.14r + 2r = 5.14r
r = 19.02/5.14 = 3.7 cm
3) 8x + 6y = 10 -8x + 6y = 2 Which statement about the system of equations is true? A) The system has exactly 1 solution B) The system has many solutions C) The system has no solution D) The system has exactly 2 solutions 3 3
Answer:
A. Exactly one solution
Step-by-step explanation:
8x+6y=10
-8x+6y=2
0+12y=12 added two equations together
12y=12
y=1
solve for x
8x+6y=10
8x+6(1)=10
8x=4
x=1/2
A new laptop is on sale for $550 dollars. To pay for it you place it on your credit card which charges 12% percent interest each month
The interest amount charged on a new laptop is on sale for $550 dollars is $66.

What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Now, 12% of 550
= 12/100 ×550
= 0.12 ×550
= $66
So, interest is $66
Therefore, the interest amount charged on a new laptop is on sale for $550 dollars is $66.

Step-by-step explanation:
In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the turbine?
A) 0 m/s
B) 15.5 m/s
C) 31 m/s
D) 46.5 m/s
Answer:
C: 31 m/s
Step-by-step explanation:
It falls from a dam.
Thus;
Initial velocity; u = 0 m/s
Height; h = 49 m
Acceleration due to gravity is 9.8 m/s²
To solve for the final velocity this, we will use Newton's third equation of motion;
v² = u² + 2gh
v² = 0² + 2(9.8 × 49)
v = √960.5
v ≈ 31 m/s

The shape is a pentagon.
The interior angles of a pentagon always add up to 540°.
When you add up all the labeled angles in the picture, you get (16x + 12).
16x + 12 = 540
16x = 528
X = 33
Step-by-step explanation:
4x-25+3x+25+3x+15+4×+2x-3=360
4x+3x+3x+4x+2x-25+25+15-2=360
16x +12=360
16x=360-12
16×÷16=348÷16

The figure is made up of a square and a rectangle. Find the area of the shaded region.
m2
please help first one correct gets barlyest
Answer:
[tex] 10 \: { \: m}^{2} [/tex]
Step-by-step explanation:
area of the shaded region = Area of triangle formed in rectangle with base (10 - 6 = 4) 4m and height 2 m + Area of triangle formed in square with base 2 m and height 6 m
[tex] = \frac{1}{2} \times 4 \times 2 +\frac{1}{2} \times 2\times 6 \\ \\ = 4+6 \\ \\ = 10 \: { \: m}^{2} [/tex]
Answer:
shaded region = 10 m squared
Step-by-step explanation:
Area square = 6x6 = 36 Area reatangle 4x2 = 8
both areas = 44
Now lets subtract some white parts to obtain the shaded parts
1/2 of 4x6 = 12
1/2 of 6x6 = 18
1/2 of 4x2 =4
12+18+4= 34
44-34 = 10
A water pipe takes 45 minutes to fill a
tank. How many water tanks it would fill in
6 hours.
Math
Answer:
It would fill 8 tanks
Step-by-step explanation:
45minutes = 3/4 of an hour
It would fill 6/(3/4) tanks in 6 hours
6/(3/4) = 6/3*4 = 2*4 = 8

Is this correct???????????!!!!please gelppp
Answer:
Step-by-step explanation: it looks right to me but who knows
Answer:
Yes
Step-by-step explanation:
The line intersects the y axis at point 4 (y > 3/2 x + 4), and for every 2 squares to the right it goes 3 squares up (y > 3/2 x + 4). Also, it's the > sign, which is correct when it goes in that direction.

An asteroid hit the earth and created a huge round crater. Scientists measured the distance around the crater as 26 miles. What is the area of the crater?
Answer:
53.8 mi^2
Step-by-step explanation:
First we need to determine the radius of the crater. The circumfence formula is C = 2(pi)r, and here C = 26 miles. Thus,
26 mi = 2(pi)r, so that
26 mi
r = ------------ = 4.13 miles
2pi
Then the area of the crater is A = (pi)r^2, or:
A = 3.14(4.13 mi)^2 = 53.8 mi^2

You have $20 to spend for cupcakes. If each cupcake costs $4, write and solve an inequality to show the maximum number of cupcakes you can buy.
Solve for x: 2(2a+3)-6=5a+2
Answer:
a=-2
We move all terms to the left:
2(2a+3)-6-(5a+2)=0
We multiply parentheses
4a-(5a+2)+6-6=0
We get rid of parentheses
4a-5a-2+6-6=0
We add all the numbers together, and all the variables
-1a-2=0
We move all terms containing a to the left, all other terms to the right
-a=2
a=2/-1
a=-2
Step-by-step explanation:
We move all terms to the left:

Answer:
a = -2
Step-by-step explanation:
2(2a+3)-6=5a+2
distrubute the 2
4a + 6 - 6 = 5a + 2
combine like terms
4a = 5a + 2
-5a -5a
-a = 2
a = -2

Ten deer were introduced into a protected preserve. Their expected population doubles each year. Which function represents the same relationship?
Answer:
y(t)= 10 (2)^t
Step-by-step explanation:
If t is the number of years given then the expected number can be found by
y(t)= 10 (2)^t
where t takes the value 0,1,2,3, and so on.
Putting t= 0
y(t)= 10 (2)^t
y(0)= 10 (2)^0
y(0)= 10 For the start the number of deer are 10.
Putting t= 1
y(t)= 10 (2)^t
y(1)= 10 (2)^1
y(1)= 20 After 1 year it has doubled to 20
Putting t= 2
y(t)= 10 (2)^t
y(2)= 10 (2)^2
y(2)= 40 After 2 years it has again doubled to 40
Putting t= 3
y(t)= 10 (2)^t
y(3)= 10 (2)^3
y(3)= 80 After 3 years it has again doubled to 80
