Answer:
11:1
Step-by-step explanation:
For every 11 copies, 1 minute passes. Four minutes passed in this case and thus 11*4 would equal 44 and 1*4 would equal 4.
Which choice could be used in proving that the given triangles are similar?
Answer: . To prove triangles are similar, you need to prove two pairs of corresponding angles are congruent
Step-by-step explanation:
SSS similarity postulate
The SSS similarity postulate says that if the lengths of the corresponding sides of two triangles are proportional then the triangles must be similar.
In the given figure , we have two triangles ΔABC and ΔXYZ such that the corresponding sides of both the triangles are proportional.
i.e.
Then by SSS-similarity criteria , we have
ΔABC ≈ ΔXYZ

Graph △RST with vertices R(4, 1), S(7, 3), and T(6, 4) and its image after the glide reflection.
Translation: (x, y)→(x−3, y)
Reflection: in the line y=−1
Answer:
Step-by-step explanation:
Points R(4,1) S(7,3) T(6,4) after translation
R(4-3, 1) S(7-3, 3) T(6-3, 4)
R'(1, 1) S'(4, 3) T'(3, 4)
Points R'(1, 1) S'(4, 3) T'(3, 4) after reflection

machine A covers 5/8 square feet in 1/4 hour or machine B covers 2/3 square feet in 1/5 hour
Answer:
The unit rate would be square footage covered in 1 hour. Since 5/8 square foot is the area covered in 1/4 hour, you would multiply by 4 to determine the amount of area covered in 1 hour:
5 x 4 = 20
8 1 8
20 is equivalent 2 and 1 square feet in 1 hour
8 2
Hope this helps! <3

Answer:
Step-by-step explanation:
tan(16)=125/a
tan(16)=35.8 (DC)
tan(7)=125/a
tan(7)=15.3
35.8-15.3=20.5
Sorry if that's incorrect, my best is 20.5 feet.
======================================================
Work Shown:
Let
x = length of AD in feet
y = length of DC in feet
x and y are positive real numbers.
For now, focus on triangle BCD. Ignore point A and its associated angle.
tan(angle) = opposite/adjacent
tan(D) = BC/DC
tan(16) = 125/y
y*tan(16) = 125
y = 125/tan(16)
y = 435.926805480113
y = 435.926805
The value of y is approximate
Now focus on triangle ABC. Ignore point D and its associated angle.
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = BC/(AD+DC)
tan(7) = 125/(x + y)
(x+y)*tan(7) = 125
x*tan(7) + y*tan(7) = 125
x*tan(7) = 125 - y*tan(7)
x = ( 125-y*tan(7) )/( tan(7) )
x = ( 125-435.926805*tan(7) )/( tan(7) )
x = 582.116498496824
x = 582
The distance from A to D is approximately 582 feet.

Answer:
The number of yards in 5 miles will be: 8800 miles
Step-by-step explanation:
The double numbers line shows the ratio of yards to miles.From the number line, it is clear that
at 2 miles, the number of yards is 3520.Thus,
The unit rate = 3520 yards / 2 miles
= 1760 yards / per mile
Thus, the number of yards in 5 miles will be:
1760 × 5 = 8800 miles
Therefore, the number of yards in 5 miles will be: 8800 miles

Joey completed 1,456 push-ups over a 4-week period. Joey did the same number of push-ups every day. How many push-ups did Joey do each day?
Answer:
Joey completed 52 pushups each day.
Step-by-step explanation:
We know that he did 1,456 pushups in 4 weeks, and that there are 7 days a week. This means that he did those pushups in the span of 28 days. So, divide 1,456 by 28 to get 52 pushups.

Answer:
5.0 ft
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relevant relationship.
Sin = Opposite/Hypotenuse
sin(38°) = x/8.2
x = 8.2·sin(38°) ≈ 5.048
x ≈ 5.0 . . . . feet
Noah said, “When you divide a number by a second number, the result will always be smaller than the first number.”
Jada said, “I think the result could be larger or smaller, depending on the numbers.”
Do you agree with Noah or Jada? Show or explain your reasoning.
Answer:
When dividing two fractions by each other, the result will be larger. Dividing two whole numbers, however, will always result in a smaller number because you're taking away a part of the number.

Answer:
( x + 5 ) · ( x + 1 )
Step-by-step explanation:
-Factoring by grouping-
First, split the middle term into two parts that are factorable by the other variables.
x² + x + 5x + 5
Factor the parts
x · ( x + 1 ) + 5 · ( x + 1 )
( x + 5 ) · ( x + 1 )
Answer:
C
Step-by-step explanation:
Given
x² + 6x + 5
Consider the factors of the constant term (+ 5) which sum to give the coefficient of the x- term (+ 6)
The factors are + 1 and + 5 , since
1 × 5 = + 5 and 1 + 5 = + 6, thus
x² +6x + 5 = (x + 1)(x + 5) → C

What is the percent error of an egg that weighs 2 oz using 2.5 oz as original value
Answer:
Percent error = 25%
Step-by-step explanation:
Find:
Percent error
Given:
Weight of egg = 2 oz
Original value = 2.5 oz
Computation:
Percent error = [(Original value - Weight of egg) / Weight of egg]100
Percent error = [(2.5 - 2) / 2]100
Percent error = 25%
