Answers
Answer:
65 degrees
Step-by-step explanation:
The missing angle on the bottom is 35 degrees. This is because it lies on a straight line with the other angle being 145 degrees and a straight line is always 180 degrees, so 180-145=35 degrees. Now we have to find x so we should add the two known angles (35+80=115) and subtract it from 180 (180-115) to get 65 degrees for x.

Steve is creating a web page. He starts with a font of 5 9/10 points and decreases it by 1/2. He decreases it again by 6/10 points. Steve then realizes that the font is to small to read easily and increases it by 1 4/5 points. Which is the best estimate of the font's final size?
Answers
Answer:
6 3/5 points
Step-by-step explanation:
Steve is creating a web page.
Step 1
He starts with a font of 5 9/10 points and decreases it by 1/2.
Hence: Current font
= 5 9/10 - 1/2
= 5 + ( 9/10 - 1/2)
Lowest common denominator
= 10
= 5 + (9 - 5/10)
= 5 + 4/10
= 5 + 2/5
= 5 2/5 points
Step 2
He decreases it again by 6/10 points.
Current fonts
= 5 2/5 - 6/10
= 5 + ( 2/5 - 6/10)
Lowest common denominator
= 10
= 5 + (4 - 6/10)
= 5 + (-2/10)
= 5 - 1/5
= 4 4/5 points
Step 3
Steve then realizes that the font is to small to read easily and increases it by 1 4/5 points.
New font
= 4 4/5 points + 1 4/5 points
Lowest common denominator = 5
= 4 + 1 + (4/5 + 4/5)
= 5+ ( 4 + 4/5)
= 5 +(8/5)
= 6 3/5 points
The best estimate of the font's final size is 6 3/5 points

A local grocery story has strawberries on sale for $1.45 per pound. How much would it cost to buy 5.5 pounds of strawberries? Round your answer to the nearest penny. Show your work on the sketchpad and type your answer below
Answers
Answer: The cost of 5.5 pounds strawberries =$ 7.98
Step-by-step explanation:
Given: A local grocery story has strawberries on sale for $1.45 per pound.
i.e. Cost for 1 pound strawberries = $1.45
Now, Cost of 5.5 pounds strawberries = 5.5 x (Cost for 1 pound strawberries)
= $ (5.5 x 1.45)
= $ 7.975 ≈ $ 7.98 [ Round to the nearest penny]
Hence, the cost of 5.5 pounds strawberries =$ 7.98
Solve the following proportion for u.
3/17 = u/13
Answers
Answer:
2.294117647
Step-by-step explanation:
3/17 = u/13
Cross multiply:
3 * 13 = 17 * u
Simplifying
3 * 13 = 17 * u
Multiply 3 * 13
39 = 17 * u
Solving
39 = 17u
Move all terms containing u to the left, all other terms to the right.
Add '-17u' to each side of the equation.
39 + -17u = 17u + -17u
Combine like terms: 17u + -17u = 0
39 + -17u = 0
Add '-39' to each side of the equation.
39 + -39 + -17u = 0 + -39
Combine like terms: 39 + -39 = 0
0 + -17u = 0 + -39
-17u = 0 + -39
Combine like terms: 0 + -39 = -39
-17u = -39
Divide each side by '-17'.
u = 2
Simplifying
u = 2.294117647
3*13=17u
39=17u
U=39/17=2.29

Work out the area of this circle with radius 11.2 take pie to be 3.142 and give your answer to 2 decimal places
Answers
Answer:
394.13 to 2 D.P.s
Step-by-step explanation:
Area = pi r^2
= 3.142 * 11.2^2
= 394.132.
The area of this circle up to 2 decimal places will be 394.13 square units.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The radius of the circle is 11.2 units and takes π to be 3.142. Then the area is given as,
A = π x (11.2)²
A = 3.142 x 125.44
A = 394.13 square units
The area of this circle up to 2 decimal places will be 394.13 square units.
