Answer:
33 braids
Step-by-step explanation:
What you want to do is first put in the equation. You put in 0.75x + 4=29.
Then you subtract 4 from 29 and get 25. Then divide 25 by 0.75 and you get the answer 33.3333333333. Round it to the nearest whole number and you get the final answer of 33 braids.
The length of a rectangle is 5 more than the width. The perimeter is 120. What is the length, width, and area? Please HELP
Answer:
l = 32.5 units, w= 27.5 units, A = 893.75 units²
Step-by-step explanation:
width is w
length is l = 5+w
P = 2( l+w) , substitute l for 5+w
P = 2(5+w+w)
P = 2(5+2w)
P = 10 +4w
P = 120
10 +4w = 120
4w = 120-10
4w = 110
w= 110/4
w= 27.5 units
l = 5+w = 5+ 27.5 = 32.5 units
A = l*w = 27.5 * 32.5 = 893.75 units ²

Write the inequality:
Two less than twice a number is less than a half.
Answer:
2x-2<1/2
Step-by-step explanation:
when the problem says "two less than" it means we are subtracting 2 from something, in this case, that something is "twice a number" as the problem states. So we would write 2x where x is a variable that represents any number so we have 2x-2<1/2.
The length of a rectangle is 2 centimeters longer than its width.
If the perimeter of the rectangle is 64 centimeters, find its length and width.
Answer: 15
Step-by-step explanation:
Let the length of the width = w.
Then, the length of the length is w + 2.
The perimeter of a rectangle is 2*length + 2*width.
Therefore, 2*(w+2) + 2*w = 64
2w + 4 + 2w = 64
4w + 4 = 64
4w = 60
w = 15

Answer:
x = 11
Step-by-step explanation:
(3x + 28) + (5x + 52) + ( 2x - 10) = 180
(3x + 5x + 2x) + (28 + 52 - 10) = 180
10x + 70 = 180
10x = 180 - 70
10x = 110
x = 11
Answer:
x= 11
Step-by-step explanation:
(3x + 5x) + (5x+52) + (2x-10)= 180 (sum of anglea in a triangle)
10x+80-10= 180
10x+70=180
10x=180-70
10x=110
x=110÷10
x=11

A container built for transatlantic shipping is constructed in the shape of a right rectangular prism. Its dimensions are 7.5 ft by 11.5 ft by 3 ft. If the container is entirely full and, on average, its contents weigh 0.15 pounds per cubic foot, find the total weight of the contents. Round your answer to the nearest pound if necessary.
Considering the definition of right rectangular prism and its volume, the total weight of the contents is 38.81 pounds.
Right rectangular prismA right rectangular prism (or cuboid) is a polyhedron whose surface is formed by two equal and parallel rectangles called bases and by four lateral faces that are also parallel rectangles and equal two to two.
Volume of right rectangular prismTo calculate the volume of the rectangular prism, it is necessary to find the product of its dimensions, or of the three edges that converge at a certain vertex.
That is, to calculate the volume of a rectangular prism, multiply its 3 dimensions: length×width×height.
Volume of the containerIn this case, you know that:
the dimensions of the container built are 7.5 ft by 11.5 ft by 3 ft. the container is entirely full and, on average, its contents weigh 0.15 pounds per cubic foot.So, the volume of the container is calculated as:
7.5 ft× 11.5 ft× 3 ft= 258.75 ft³
Then, the total weight of the contents is calculated as:
258.75 ft³× 0.15 pounds per cubic foot= 38.8125 pounds≅ 38.81 pounds
Finally, the total weight of the contents is 38.81 pounds.

What are the correct answers
NEED ANSWER ASAP PLEASE
Answer:
Step-by-step explanation:
4) A photograph costs $20, so the cost of x photographs is 20x.
Similarly, the cost of y prints is $25.
So the total cost is 20x+25y, and this has to be less than or equal to 400, so C.
5) just plug each pair in.
For example for the first option, x=5 and y=10, and since 20(5)+25(10)=100+250. which is less than or equal to 400, it works.

9x+3y-27=0
(Y)
Answer:
y = 9 - 3x
Step-by-step explanation:
9x + 3y - 27 = 0 ( add 27 to both sides )
9x + 3y = 27 ( subtract 9x from both sides )
3y = 27 - 9x ( divide through by 3 )
y = 9 - 3x

Joe's total bill for pizza and soft drinks was $27.50. He left a
20% tip for their server. How much tip did he leave?
Answer:
$5.50
Step-by-step explanation:
100% of the total bill was $27.50
10% will be 100% divided by 10
10% = $27.50 ÷ 10
10% = $2.75
20% will be double 10%
20% = £2.75 × 2
20% = $5.50

We've got base lengths, that's what we will use to find the scale factor.
27.3 ÷ 15.6 = 1.75 s.f
We're going from big triangle, to small; so, divided by 1.75s.f to find length of u
56 ÷ 1.75 = 32
U= 32m

The best prediction of the average annual salary of a professional football player in 2025 is $4,166,000
Exponential functionAn exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Let y represent the average annual salary, x years since 2000, hence, from table:
At (2000, 1116000), that is (0, 1116000):
1116000 = ab⁰
a = 1116000
At (20, 3193000):
3193000 = 1116000(b)²⁰
b = 1.05
The salary in 2025 ( x = 25) is:
y = 1116000(1.05)²⁵ = 4152719.5
The best prediction of the average annual salary of a professional football player in 2025 is $4,166,000
