4 loads of stone weigh23ton. Find the weight of 1 load of stone.
Answer: 1 load of stone weighs 5.75 tons.
Step-by-step explanation: You'll need to divide 23 by 4 leaving you with 5.75. This will help you get a number that is potentially the weight of 1 load. To check to see if this is right, multiply 5.75 by 4 to get 23.
Brady needs to cut a piece of scrapbook paper
12 centimeters long. He cuts pieces of the following
lengths. Which cut results in a percent error of 15%?
Select all that apply.
Answer:
Option A and Option C
Step-by-step explanation:
If we know that we have to cut a peice of paper 12 centemiters long, that means a 15% error would be cutting out one of the following lengths....
12 - 12(0.15) = 10.2 cm
or
12 + 12(0.15) = 13.8cm
So from this, we see that the answers are Option A and Option C

Answer:
Sqaure root of 3 divided by 2
Step-by-step explanation:
The value of function sin 60° is √3/2.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We need to find the value of sin 60°
Sin 60 degrees is nothing but sin π/3
The sine function we obtain by dividing the opposite side by hypotenuse.
sin theta = Opposite side/ hypotenuse
sin 60=√3/2
The value of sin 60 degrees is square root of three by two.
Hence, the value of function sin 60° is √3/2.

Answer: 8 1/20 or 8.05.
Step-by-step explanation: First you would want to make 9 3/4 - 2 1/5 to 39/4 - 11/5. We need to get the LCD or Least Common denominator of 4 and 5, which is 20. The rule is what you multiplied the denominator by you must multiply the numerator by, so our new equation is 195/20 - 44/20, which is 151/20. Now, we have to find the LCD of 2 and 20, which is 10. So 151/20 + 10/20 is 161/20 or 8 1/20.

using the elimination method, what is x and y ( please explain, I am still slightly confused)
x + 3y= -1
-2x - 3y=5
Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
x + 3y = - 1 → (1)
- 2x - 3y = 5 → (2)
Adding the 2 equations term by term will eliminate the y- term
- x + 0 = 4
- x = 4 ( multiply both sides by - 1 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
- 4 + 3y = - 1 ( add 4 to both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (- 4, 1 )

The volume of a rectangular box is 1600 cubic inches. The height of the box is 8 inches and the length of the box is 2 times longer than the width of the box. What is the width of the box "IN FEET FT"?
Answer:
0.833 feets
Step-by-step explanation:
Given that:
Volume of box = 1600
Heigh of box (H) = 8 inches
Let:
Width of box (W) = x
Length of box (L) = 2x
Volume of box = (Height * width * length)
1600 = (8 * x * 2x)
1600 = 16x²
x² = 1600/16
x² = 100
x = sqrt(100)
x = 10 inches
Hence, width of box in feet:
1 inch = 0.0833 feets
10 inches = (10 * 0.0833) feets
= 0.833 feets

Answer:
A
Step-by-step explanation:
x/y - x/y-1
But remember the fraction with the bigger denometer is the smaller number
x/y is the smaller number
therefore the answer is:
x/y-1 - x/y or A
The expression represents the positive difference between the two people's hourly wage is x.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Given that, Angelo makes x dollars for y hours of work.
Money made by Angelo =x×y
= xy
Sarah makes the same amount of money working 1 hour less.
Number of hours Sarah worked is y-1
Money made by Sarah =x×(y-1)
= xy-x
So, difference in their money
xy-(xy-x)
= xy-xy+x
= x
Therefore, the expression represents the positive difference between the two people's hourly wage is x.

Here is an identity.
a(4x – 10) = 24x + 5b
Work out the values of a and b
Answer:
The value of a is 6 and the value of b is -12
Step-by-step explanation:
Given identity is:
a(4x – 10) = 24x + 5b
We can use the comparison of coefficients method to find the values of a and b
So,
By simplifying the left hand side of identity
[tex]4ax-10a = 24x+5b\\4ax+(-10)a = 24x+5b[/tex]
Comparing the co-efficient of x
[tex]4a = 24\\a = \frac{24}{4}\\a = 6[/tex]
Comparing the constant terms
[tex]-10a = 5b[/tex]
Putting the value of a
[tex]-10(6) = 5b\\-60 = 5b\\b = \frac{-60}{5}\\b = -12[/tex]
Hence,
The value of a is 6 and the value of b is -12

Answer:
The distance is 29.3 feet
Step-by-step explanation:
Here, we want to find the distance from the diving board to the bottom of the pool
To get this, we will need to add the height of the diving board above the ground plus the distance of the bottom of the pool below the ground
Mathematically, we can have this as:
12.4 + 16.9
= 29.3 feet
