Answer:
43 inches
Step-by-step explanation:
Accumulation rate per hour = 0.8 inch / hour
If the snow continues at that rate for 54 hours ;
To obtain the amount of snow that will accumulate, we multiply the Accumulation rate per hour by the number of hours given ;
Accumulation rate per hour * number of hours
= 0.8 inch/hour * 54 hours
= 43.2 inches
= 43 inches (nearest whole number)
Suppose that 13 inches of wire costs 65 cents. at the same rate, how many inches of wire can be bought for 35 cents?
One can buy 7 inches of wire for 35 cents.
In both the British imperial and American customary systems of measurement, the inch serves as a unit of length.
A problem can be solved using the unitary method by first determining the value of a single unit, and then multiplying that value to determine the required value.
The cost of 13 inches of wire is 65 cents.
Using the unitary method,
65 cents = 13 inches of wire
1 cents = ( 13 / 65 ) inches of wire
Now, multiplying 35 on both sides of the equation we get:
35 × 1 cents = ( 13/ 65) × 35 inches of wire
35 cents = ( 455 / 65 ) inches of wire
35 cents = 7 inches of wire
Hence, 7 inches of wire can be bought for 35 cents.

Yesterday, she did 1 haircut and colored the hair of 2 clients, charging a total of $217. Today, she did 2 haircuts and colored the hair of 1 client, charging a total of $155. How much does Norma charge for her services? PLEASE ANSWER
Answer:
Cost of haircut = $93
Cost of colouring hair = $31
Step-by-step explanation:
Let
Cost of haircut = x
Cost of colouring hair = y
The equations
x + 2y = 217 (1)
2x + y = 155 (2)
From (1)
x = 217 - 2y
Substitute x = 217 - 2y into (2)
2x + y = 155
2(217 - 2y) + y = 155
434 - 4y + y = 155
-3y = 155 - 434
-3y = -279
y = -279 / -3
= 93
y = $93
Substitute y = 93 into (1)
x + 2y = 217
x + 2(93) = 217
x + 186 = 217
x = 217 - 186
= 31
x = $31
Cost of haircut = $93
Cost of colouring hair = $31

Which of the following equations has an infinite number of solutions?
A. 3x – 3 = –4x
B. 2y + 4 – y = 16
C. 7x + 5 = 4x + 5 + 3x
D. 6y – 2 = 2(y – 1)
The equation 7x + 5 = 4x + 5 + 3x has an Infinite number of solutions. which is the correct answer would be option (C).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have to determine which equation has an infinite number of solutions
As per option (C),
⇒ 7x + 5 = 4x + 5 + 3x
Combine comparable terms to simplify both sides of the problem.
You have become left with 7x+5 = 7x+5.
On both sides, subtract 7x.
This gives you 5=5.
Subtraction 5 from both sides
⇒ 0 = 0
Thus, this equation has an Infinite number of solutions.
Hence, the correct answer would be an option (C).

What is Equation of line?
An equation in slope intercept form of the line with slope m is,
y = mx + b
Where, b is y-intercept.
Given that;
In the graph y-intercept at 5.
And two points are (-4, 4) and (4, 6).
Now, Let two points on the graph are (-4, 4) and (4, 6).
Hence, Slope (m) = 6 - 4 / 4 - (-4)
= 2/8
= 1/4
And, On the graph y - intercept is 5.
Hence, Value of y - intercept (b) = 5

A boy scout troop is selling bags of popcorn and boxes of cookies to fund their troops next trip. The popcorn sells for 10 dollars a bag and the cookies sell for 5 dollars a box. The troop sells 32 items and makes 210 dollars. Write a system that could be used to determine how much popcorn and cookies the troop sold.
Answer:
c + p = 32
5c + 10p = 210
Step-by-step explanation:
Given that :
Cost of popcorn per bag = $10
Cost of. Cookies per box = $5
Total items sold = 32
Total.amout made = $210
Let number of cookies = c ; number of popcorn = p
c + p = 32
5c + 10p = 210
c = 32 - p
5(32 - p) + 10p = 210
160 - 5p + 10p = 210
5p = 50
p = 10
c = 32 - p
c = 32 - 10
c = 22

find the amount of hardener needed for 600g of carbon fiber if the ratio of the composite is 40% matrix to 60% fiber and the ratio of the matrix is 100 parts resin to 27 parts of hardener
The hardener needed for 600 g of carbon fiber is 85.04 g.
We are given that the ratio of the composite is 40 % matrix to 60 % fiber.
This can be written as:
Matrix : fiber = 40 % : 60 %
Matrix : fiber = 40 : 60
Matrix : fiber = 2 : 3
Now, we know that the carbon fiber = 600 g
Matrix : 600 g = 2 : 3
Matrix / 600 = 2 / 3
Matrix = 1200 / 3 g
Matrix = 400 g
Also, we are given that the ratio of the matrix is 100 parts resin to 27 parts of hardener.
This means that:
Hardener = 27 / 127 of matrix.
Hardener = 27 / 127 × ( 400 g )
Hardener = 85.04 g
Therefore, the hardener needed for 600 g of carbon fiber is 85.04 g.

=============================================
Work Shown:
Refer to the diagram below. I've added a line segment and two variables y and z. This forms two isosceles triangles.
The central angle 56 degrees subtends the same arc as the inscribed angle y. By the inscribed angle theorem, this means y = 56/2 = 28. The inscribed angle is always half of the central angle (when both angles subtend the same arc).
Focus on the smaller isosceles triangle that has angles 56, z and z. Those three angles add to 180
z+z+56 = 180
2z+56 = 180
2z = 180-56
2z = 124
z = 124/2
z = 62
Now focus on the larger isosceles triangle (angles y = 28, x+z and x+z)
We'll use the same trick as before.
(x+z)+(x+z)+(y) = 180
(x+62)+(x+62)+(28) = 180 ... plug in z = 62 and y = 28
2x+152 = 180
2x = 180-152
2x = 28
x = 28/2
x = 14
Given CAD is a right angle and AB is bisecting CAD and if DAB=(7x-4) find X
Answer:
x = 7
Step-by-step explanation:
∠CAD is a right angle, right angles has 90° measurement.
m∠DAB = 7x - 4 AB bisects ∠CAD this means it divides the angle into two equal parts.
So it's safe to write the following equation:
7x - 4 = 45 (half of 90°)
add 4 to bot sides
7x = 49 divide both sides by 7
x = 7
