Answer:
A. 4.1 yards
Step-by-step explanation:
Multiply $10.25 by 2 because there is 2 fabrics. You would get 20.5 and divide 20.5 from 85.00 and the answer is 4.1.
He buys 5.6 yards of wool, the correct option is B.
What is the equation?In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
A tailor pays $10.25 per yard for wool and pays $5.75 per yard for cotton.
He bought 4.8 yards of cotton and spent a total of $85.00 on the two types of fabric.
Let x be the yards of wool did he buy.
The yards of wool did he buy is given by;
[tex]\rm 10.25x + 5.75 \times 4.8 = 85\\\\10.25 x=85-27.6\\\\10.25 x=57.4\\\\x=\dfrac{57.4}{10.25}\\\\x=5.6[/tex]
Hence, he buys 5.6 yards of wool, the correct option is B.

14. Calculate A bird
weighing 15 g eats 10 times
its weight in food in a week.
How much food does the
bird eat in a day?
Answer:
21.429 grams per day
Step-by-step explanation:
15g times 10 =150g
150g/7 =21.429g per day
Final answer:
A bird that eats 10 times its weight in food per week, with a weight of 15 g, consumes approximately 21.43 g of food per day.
Explanation:
If a bird weighing 15 g eats 10 times its weight in food in a week, we first calculate the total amount of food the bird eats in a week and then divide that by 7 to find the daily intake.
First, we calculate the weekly food consumption:
The bird's weight = 15 g
Total weekly food intake = 15 g × 10 = 150 g
Daily food intake = Total weekly intake ÷ 7
Daily food intake = 150 g ÷ 7 ≈ 21.43 g
Therefore, the bird eats approximately 21.43 grams of food per day.

The blueprint for the Pelham's living room has a scale of 2 inches=5 feet. The family wants to use a scale of 1 inch=44 feet. What is the width of the living room on the new blueprint?
(the original width is 8)
Using the original scale of 2 inches = 5 feet, the living room is 20 feet wide. With the new scale of 1 inch = 44 feet, the width of the living room on the new blueprint would be 2.2 inches.
Explanation:To solve this problem, one must first determine the actual width of the living room using the original scale. According to the original scale, 2 inches represent 5 feet. This would mean that the actual width of 8 inches would represent (8 / 2) * 5 = 20 feet. Now, set up a proportion with the new scale, which is 1 inch = 44 feet. If x is the width on the new blueprint, we would have x / 44 = 1 / 20, solving for x gives us x = 44 / 20 = 2.2 inches. Therefore, the width of the living room on the new blueprint would be 2.2 inches.

Which pyramid has a greater volume, and how much greater is its volume?
A rectangular pyramid on the left with a base of 7 inches by 6 inches and height of 3 inches.
A rectangular pyramid on the right with a base of 4 inches by 3 inches and a height of 10 inches.
a). The volume of the pyramid on the left is greater by 2 inches cubed.
b). The volume of the pyramid on the left is greater by 6 inches cubed.
c). The volume of the pyramid on the right is greater by 2 inches cubed.
d). The volume of the pyramid on the right is greater by 6 inches cubed.
Answer:
a). The volume of the pyramid on the left is greater by 2 inches cubed.
Step-by-step explanation:
The volume of a rectangular based pyramid is
V = [tex]\frac{1}{3}[/tex] w b h
Where w, and b are the lengths of the base of the pyramid, and h is the height of the pyramid
Substitute the values given for both pyramids into the equation, and solve for V
Left Pyramid:
V = [tex]\frac{1}{3}[/tex] w b h
V = [tex]\frac{1}{3}[/tex] * 7 * 6 * 3
Volume of Left Pyramid = 42 [tex]inches^{3}[/tex]
Right Pyramid:
V = [tex]\frac{1}{3}[/tex] w b h
V = [tex]\frac{1}{3}[/tex] * 4 * 3 * 10
Volume of Right Pyramid = 40 [tex]inches^{3}[/tex]
Subtract the two volumes to find the difference in volume
42 - 40 = 2 [tex]inches^{3}[/tex]
Answer:
The volume of the pyramid on the left is greater by 2 inches cubed.

6(a+3)=2a+30 what is the answer
Answer:
a = 3
Step-by-step explanation:
6(a+3)=2a+30
Distribute
6a + 18 = 2a+30
Subtract 2a from each side
6a + 18 -2a= 2a+30-2a
4a +18 =30
Subtract 18 from each side
4a+18-18 = 30-18
4a = 12
Divide each side by 4
4a/4 = 12/4
a = 3

Answer:
D
Step-by-step explanation:
Since this is right triangle, we can use the Pythagorean Theorem.
a^2+b^2=c^2
where a and b are the legs, and c is the hypotenuse.
14 and 16 are the legs, because they form the right angle. x is the hypotenuse, because it is opposite the right angle.
14^2+16^2=x^2
Evaluate the exponents
196+256=x^2
Add
452=x^2
To get this is simplest radical form, find the greatest square root that divides evenly into 452
4 is the greatest square root. 4 times 113 equal 452
So, we have
[tex]\sqrt{4}\sqrt{113}[/tex]
Take the square root of 4
2[tex]\sqrt{113}[/tex]
So, choice D is correct.

If the diameter of a men’s basketball is 10 inches and a women’s is 9 inches, what is the approximate difference of their volumes?
Answer:
141.89526818714 cubic inches
Step-by-step explanation \
Vm = Volume of the men's basketball
Vm = (4/3)*pi*r^3
Vm = (4/3)*pi*(5)^3 ... diameter = 10 --> radius = 10/2 = 5
Vm = 523.598775598299 cubic inches
Vw = Volume of the women's basketball
Vw = (4/3)*pi*r^3
Vw = (4/3)*pi*(4.5)^3 ... diameter = 9 --> radius = 9/2 = 4.5
Vw = 381.70350741116 cubic inches
Difference in volume = Vm - Vw
Difference in volume = 523.598775598299 - 381.70350741116
Difference in volume = 141.89526818714 cubic inches
This result is approximate
