Answer:
D
Step-by-step explanation:
u dont really need a calculator for this problem
to find the answer, you have to look at the equation.
f(x)=20x+4
the 4 is the y-intercept (0,4), which tells us that the range will start from number 4.
the 20x tells u to multiply the x by the 20
so if it was 20(1)=20, 20(2)= 40, 20(3)= 60 ....
so if you add x amount of plates to the barbell, it will be 20 times x plus 4(because 4lbs is the weight of the barbell itself)
so 0 plates is 4, 1 plate is 20(2) + 4 = 44, 20(4)+4= 84 ....
(i didnt do 20(1) or 20(3) because you need to have a even number of plates of each side of the barbell.)
please I need help ASAP

-2x-5y=3 3x-8=-6 solve by substition
Answer:
x = 2/3
y = -13/15
Step-by-step explanation:
3x – 8 = -6
+8 +8
[addition property of equality]
3x = 2
÷3 ÷3
[division property of equality]
x = 2/3 → -2x – 5y = 3
[substitution property]
-2(2/3) – 5y = 3
[distributive property]
-4/3 – 5y = 3
[Create the proportional equivalent of each term so that all terms share the same denominator]
-4/3 – 15y/3 = 9/3
[multiplication property of equality]
3 ( -4/3 – 15y/3 ) = 3 ( 9/3 )
[distributive property]
-4 – 15y = 9
+4 +4
[addition property of equality]
-15y = 13
÷-15 ÷-15
[division property of equality]
y = -13/15

Answer:
43.8 is the Area but i don't know about the perimeter
Step-by-step explanation:
Answer:
are = 40.2, perimeter = 28.2
Step-by-step explanation:
perimeter = 6+6(blue triangle)+3(pink triangle)+4.2+3 (green parallelogram) +3+3 (purple square) = 28.2
area =
6 * 6 * 1/2 = 18 blue triangle
3*3*1/2 = 4.5 pink triangle

(geometry) This zigzag crystal vase has a height of 12 inches. The cross sections parallel to the base are always rectangles that are 5 inches wide by 4 inches long.
(a) If we assume the crystal itself has no thickness, what would be the volume of the base?
(b) The crystal is actually half an inch thick on each of the sides and on the bottom. Approximately how much space is contained within the vase?
Answer:
A. 9
B. 7
Step-by-step explanation:
a) The volume of the base of the crystal is 240 inches³
b) The space contained by the vase of the crystal is 24 inches³
What is the volume of a Cuboid?A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges
The volume of a cuboid is the product of its length , width and height
The volume of the cuboid is given by
Volume of Cuboid = Length x Width x Height
Given data ,
(a) Since the cross sections are always cuboids that are 5 inches wide by 4 inches long, the area of each cross section is 5 x 4 = 20 square inches. Since the vase has a height of 12 inches, the volume of the vase is equal to the product of the area of the base and the height, which is 20 x 12 = 240 cubic inches.
(b) If the crystal is half an inch thick on each of the sides and on the bottom, then the dimensions of each cross section are 5 inches by 4 inches by 1 inch (since each side of the crystal adds half an inch to the length and width of the rectangle). The volume of each cross section is therefore 5 x 4 x 1 = 20 cubic inches.
However, since the crystal takes up half an inch on each side, the actual space contained within the vase is reduced by 2 x (5 + 4 + 0.5 + 0.5) x 12 = 216 cubic inches (where 5 + 4 is the sum of the lengths and widths of the rectangle, and 0.5 + 0.5 is the thickness of the crystal on each side).
Hence , the approximate space contained within the vase is 240 - 216 = 24 cubic inches

Answer:
minimum number-0
mean- 10.83
median-10
Step-by-step explanation:
Answer:
The minimum number is 0,
The mean is 11,
and the median is 10
Step-by-step explanation:
The minimum number is the smallest number in a data set, so that's 0.
The mean is the average of all the numbers, so if you add all the numbers in a data set together and then divide by the amount of numbers there are, you get the mean. 10 + 25 + 0 + 5 + 10 + 15 is 65, and 65 divided by 6 is 11. [Rounded to the nearest whole number.]
The median is the number that is right in the middle of the data set, so 10 is right in between 0 and 25.

On a road trip, Lota drives 55 miles each hour. The table below shows how far she travels each hour.
h hrs of driving 1 2 3 4 5 6
m miles completed 55 110 165 220 275 330
Which equation represents the relationship between h, the number of hours she drives and m the number of miles she completes?
m = h/55
m = 55/h
m = 55h
m + h = 55
Answer:
I believe the answer is M=55/h
Answer:
m = 55h
Step-by-step explanation:
m= 55h or
h*55=m

Answer: A
Step-by-step explanation:
Mr. Torres spent $40.00 to buy 18 pounds of ground beef and chicken for a family to cook out. If the price of ground beef was $4.00 per pound and the chicken was $2.00 per pound, how many pounds of each did he buy?
Answer:
They bought 2 pounds of ground beef and 16 pounds of ground chicken.
Step-by-step explanation:
Let b be the beef, and c be the chicken:
b + c = 18, the pounds of beef and the pounds of chicken added equal 18 pounds
4b + 2c = 40, the beef costs 4 dollars per pound and the chicken costs 2 dollars per pound. They add up to 40 dollars total.
Use the equation b + c = 18 and subtract c from both sides to get b = 18 - c. We replace this equation with b in 4b + 2c = 40 to get 4(18 - c) + 2c = 40 because b is 18 - c.
Now we solve for c:
4(18 - c) + 2c = 40
Simplify:
72 - 4c + 2c = 40
Combine Like Terms:
72 - 2c = 40
subtract 72 from both sides:
-2c = -32
Divide Both Sides by 2:
-c = -16
Make the Equation Positive:
c = 16
Okay cool, now we know that they bought 16 pounds of chicken, to find out how much beef the bought, replace c by 16 in b + c = 18 to get b + 16 = 18
b + 16 = 18
Subtract 16 from both sides:
b = 2, they bought 2 pounds of beef
To check, replace c with 16 and b with 2 in 4b + 2c = 40 to get
4(2) + 2(16) = 40
Multiply:
8 + 32 = 40
40 = 40
The equation is true

Answer:
Runner #2 has the fastest pace.
Step-by-step explanation:
Runner #1's pace is 10 minutes per mile. You can see this shown in the graph where the line hits the halfway mark on the y axis at one minute, or (1,10). This is the unit rate of minutes per mile for Runner #1's speed.
Runner #2's pace is 8.5 minutes per mile. You can see this shown in the equation used to represent their speed, t=8.5d. T stands for time and d stands for distance. This means that 8.5 represents how much time it takes to travel the distance of a mile. This is the unit rate of minutes per mile for Runner #2's speed.
Runner #3's pace is 9 minutes per mile. You can see this shown in the table through division. To figure out how much time it takes to travel one mile, you need to divide the time by the distance. 18÷2=9, 36÷4=9, 54÷6=9 72÷8=9, 90÷10=9, and so on. The pattern here is that the result is all 9. This is the unit rate of minutes per mile for Runner #3's speed.
10>8.5 8.5<9
It takes Runner #2 the least amount of time to travel a mile, so Runner #2 has the fastest pace.
Hope this helps!

Answer:
x = 20
Step-by-step explanation:
Use Pythagorean Theorem to solve for x:
a^2 + b^2 = c^2
Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)
12^2 + 16^2 = x^2
(12*12) + (16*16) = x^2
144 + 256 = x^2
400 = x^2
Take square root of both sides to solve for x
sqrt(400) = sqrt(x^2)
20 = x or x = 20
