Answer:
8
Step-by-step explanation:
1/10 bottle of paint covers 2/5 of box
2 bottles of paint will cover x of box
Using cross multiplication :
1/10 = 2 / 5
2 = x
(1 / 10)x = 2/5 * 2
x / 10 = 4 / 5
Cross multiply :
5x = 40
Divide both sides by 5
x = 40/5
x = 8
Hence, 2 bottles of paint will be used to paint 8 boxes

What is the value of x?
Answer:
Step-by-step explanation:
Step One
Find the supplement of both exterior angles. They both have angles that add with them to make 180 degrees.
x + 105 = 180 Subtract 105 from both sides
x = 180 - 105
x = 75
y + 148 = 180 Subtract 148 from both sides
y = 180 - 148
y = 32
Step Two
There are two ways to conclude the problem. You could find the value of the 3rd angle of the triangle, or you could notice that x is going to be the sum of the 2 angles you just found. These two angles are called the remote interior angle.
Method One
x = 32 + 75
x = 107
Method Two
32 + 75 + y = 180
107 + y = 180
y = 180 - 107
y = 73
The sum of x + 73 = 180
x = 180 - 73
x = 107

What is the probability that the spinner will land on either yellow (y) or green (g)?
A: 1/4.
B: 1/3.
C: 1/2.
D: 2/3.
Answer:
I believe it's 1/3
I haven't done these in a while, but basically since there is 6 places and it's asking the probability of it landing on 2 out of the 6, so the answer would be 2/6. Since the answer isn't there, just simpify. 2/6 simplified is 1/3. I'm so sorry if wrong, I haven't done this in a while!

consider the graph f(x)=3 to the power of x. describe how to graph the transformation f(x-3)+2
Answer:
shift the graph horizontally to the right for 3 units and then shift vertically up 2 units
Step-by-step explanation:
f(x) = x³ vs f(x-3)+2
f(x-3) will shift the graph horizontally to the right for 3 units
+2: will shift vertically up 2 units
Explain how you would determine the slope and y-intercept of a line
when given a table, graph and an equation.
I KISS YOUR TOES IF YOU HELP ME
Answer:
slope is m= y_2-y_1/x_2-x_1 and the y-intercept is where the line crosses over the x-axis
Step-by-step explanation:
fill in the points and do the equation m= rise(y points)/ run(x points)
m=slope
(x_1, y_1) =coordinates of first point in the line
(x_2, y_2)=coordinates of second point in the line
A project manager has ordered 252 pallets of concrete blocks for a construction project. Casone's trucks can each carry 14 pallets of blocks at a time. The project manager used partial quotients to find the number of delivery trucks to expect. His work is shown at the right. Is his solution correct? Explain
Answer:
18 trucks of delivery
Step-by-step explanation:
Total pallets of concrete blocks ordered = 252 pallets
If each truck can carry 14pallets, then;
1 truck = 14pallets
To determine the number of delivery truck 252pallets can carry, we can express this as:
x truck = 252pallets
Divide both expressions
1/x = 14/252
Cross multiply
14x = 1×252
14x = 252
x = 252/14
x = 18
Hence the manger should expect 1 18 trucks of delivery

The table shows the test scores and the sleep averages of several students.
a. Write the least squares regression equation that models the data. Let x = hours of sleep and y = test score.
b. Use the equation to determine the approximate test score of a student who sleeps an average of 8 h a night. Show your work.
hey someone else has already answered this!
a. To find the least squares regression equation for a group of (x,y) points:
Step 1: For each point(x,y), we need to calculate x² and xy first.
Step 2: Sum all x, y, x² and xy, which gives us Σx, Σy, Σx² and Σxy
Step 3: Calculate Slope m: m = (NΣxy − Σx Σy)/ N(Σx²) − (Σx)² , here N is the number of data.
Step 4: Calculate Intercept b: b = Σy − m(Σx)/ N
Step 5: Assemble the equation as y= mx+b
Here, we have ∑x = 120, ∑y= 1379, ∑x²= 919.5, ∑xy= 10466 and N= 16
So, m= (NΣxy − Σx Σy)/ N(Σx²) − (Σx)²
=
=
=
= 6.33
and b = Σy − m(Σx)/ N
=
=
=
= 38.71
So, the least squares regression equation is : y= mx+b ⇒ y= 6.33x +38.71
b. When x= 8, then y= (6.33×8)+38.71 = 50.64 + 38.71 =89.35
The approximate test score of a student who sleeps an average of 8 h a night is 89.35%
EVERYTHING IS FROM sicista on brainly!
Answer:
A way to write the least regression equation that models is data y = mx + b => y= 6.33x + 38.71 and as for problem B when X = 8 then y = (6.33 x 8) + 38.71 = 50.64 = 38.71 = 89.35 so the estimated test score of a student who sleeps eight hours a night is equal to 89.39%

Step-by-step explanation:
if the simple answer interest on 2,000 for 10 years is 1,600, then what is the interest rate
Answer:
8%
Step-by-step explanation:
Solving our equation
r = 1600 / ( 2000 × 10 ) = 0.08
r = 0.08
converting r decimal to a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to
accumulate simple interest of $ 1,600.00
from a principal of $ 2,000.00
over 10 years is 8% per year.

Xxx yyy -12−12minus, 12 141414 -2−2minus, 2 212121 888 282828 What is the xxx-intercept of the line?
Answer:
-12Step-by-step explanation:
Let the equation of the line be x = y - 12
The x intercept occurs at y = 0
Substitute y = 0 into the equation
x = 0 -12
x = -12
Hence the x intercept of the line is -12
Note that the equation was assumed. The same calculation can be employed for any equation given
