Billy has 1 gallon of paint. He is going to pour it into a paint tray that measures 10 inches wide, 14 inches long, and 4 cm deep.
(1 gallon = 231 inches cubed , 1 inch = 2.54 cm)
Which of the following scenarios will happen?
Answer:
The paint will not fill the tray by 10.53 in3.
Step-by-step explanation:
Length = 14 inches
Width = 10 inches
Depth = 4 cm = 1.57 inches
Volume = length x width x depth
Volume = 14 x 10 x 1.57
= 220.47 inches cube
Volume of Gallon = 231 inches cube
Use substitution to solve the
following system of equations.
- 4y - 5x = 30 AND x= y + 3
Answer:
The solution to the system of equations is y = -5 and x = -2.
Step-by-step explanation:
The question tells us to use substitution to solve the system. This means that the given value for x (in terms of y) should be substituted into the other equation. This is modeled below:
-4y - 5x = 30
-4y - 5(y+3) = 30
Next, we should use the distributive property to simplify the left side of the equation.
-4y -5y - 15 = 30
The next step is to combine like terms on the left side of the equation.
-9y - 15 = 30
Then, we can add 15 to both sides of the equation.
-9y = 45
Finally, we can divide both sides of the equation by -9.
y = -5
To find the value for x, we substitute in the value we just found for y into either of our original equations.
x = y + 3
x = -5 + 3
x = -2
Therefore, the correct answer is y = -5 and x = -2.

which of the folowing could be the equation for a parabola that opens to the left with vertex (-17, 2)
Answer:
x = a(y+17)^2 + 2 where a < 0
Step-by-step explanation:
Since the parabola is horizontal, the formula of the parabola is x = a(y-h)^2 + k where (h,k) is the vertex.
Since it opens to the left, a must be negative. The vertex is (-17, 2), so h = -17 and k = 2.
Substituting these in, we find that the equation is
x = a(y+17)^2 + 2 where a is a real number that is less than 0 (i.e. negative)

A sum of money is shared in the ratio of 2: 5 between Mark and Peter, respectively. If Mark got $200, how much money did Peter receive?
Answer:
Step-by-step explanation:
Set this up as a proportion of M:P
[tex]\frac{M}{P}:\frac{2}{5}=\frac{200}{x}[/tex] and cross multiply to solve for x:
2x = 1000 so
x = 500. Peter got $500

A bag contains 7 red marbles, 8 blue marbles, and 5 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be red?
Answer:
0.031
Step-by-step explanation:
The probability of the first marble being green is 7/20, the second marble, 6/19, and the third, 5/18.
7/20 x 6/19 x 5/18=
0.03070175438

Question
The average of 10 numbers in a list is 16. If two of the numbers in the list are each increased by 5, by how much will the average of the 10 numbers in the list be increased?
[please help]
Answer:
Step-by-step explanation:
Lets understand what the question says:-
Mean or average in a list=16
Total sum of observations= x
Equation:-
x/10=16
x=160
If 2 numbers are increased by 5 that means
New sum of observations=160+10=170
Therefore,
New average or new mean=170/10=17
Therefore the average gets increased by 1
What is the smallest perimeter a rectangle of area 12 cm can have?
A.12 cm
B.14 cm
C.16 em
D.26 cm
Answer:
14 cm
Step-by-step explanation:
The maximum area of a rectangle (actually square) with a perimeter of 14 can have is 12.25 cm². So the smallest perimeter a rectangle of 12 cm² i just a little below 14 cm, namely 4sqrt(12) = 13.86 cm.

What is the product? (x + 3)(2 x minus 1) 2 x squared minus 3 2 x squared + 6 x 2 x squared + 5 x minus 3 2 x squared + 6 x minus 3
Answer:
2x² + 5x - 3
Step-by-step explanation:
(x + 3)(2x - 1)
Use FOIL
First terms
x * 2x = 2x²
Outer terms
x * -1 = -x
Inner terms
3 * 2x = 6x
Last terms
3 * -1 = -3
---------------------
FOIL
2x² - x + 6x - 3
Combine like terms
2x² + 5x - 3
give the answer in cm^2
p.s the answer is not 66
Answer:
45 cm^2
Step-by-step explanation:
area of the figure
split the figure and form to figure rectangle and square
for rectangle
length = 6 cm + 3 cm
=9 cm
breadth = 4 cm
area of rectangle = l*b
=9 cm * 4 cm
=36 cm^2
for square
length =3 cm
area of square = (3 cm)^2
=9 cm^2
area of figure = area of rectangle + area of square
=36 cm^2 + 9 cm^2
=45 cm^2

A bank account has an initial deposit of $14,000. After 8 years, the bank account
has $18,000. Assuming that compounding interest is done annually and that no
withdrawals are taken, find the annual interest rate on the investment. If the interest is compounded annually what is the approximate interest rate on the investment?
Answer:
2.3%
Step-by-step explanation:
18000 = 15000( 1 + i)^8
Divide both sides by 15000
1.2 = (1 + i)^8
Take both sides to the 1/8 power
1.2^(1/8) = 1 + i
1.023051875220463 = 1 + i
Subtract 1 from both sides
i = 0.023051875220463
~ 2.3%
