Answer: Aproxamatly 18.999999999999999
Step-by-step explanation:
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

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

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%

Wich ordered pair is a solution to the followimg inequality?
[tex]y\leq \frac{2}{5}x-2[/tex]
(5,0)
(0,5)
(-2,5)
(-5,2)
Answer:
Option A: (5,0)
Step-by-step explanation:
Given
[tex]y \leq \frac{2}{5}x-2[/tex]
Required
Select an ordered pair
Option A: (5,0)
This means
[tex]x = 5[/tex] [tex]y = 0[/tex]
Substitute these values in [tex]y \leq \frac{2}{5}x-2[/tex]
[tex]0 \leq \frac{2}{5} * 5 - 2[/tex]
[tex]0 \leq 2 - 2[/tex]
[tex]0 \leq 0[/tex]
This is a true statement.
Option B: (0,5)
This means
[tex]x = 0[/tex] [tex]y = 5[/tex]
Substitute these values in [tex]y \leq \frac{2}{5}x-2[/tex]
[tex]5 \leq \frac{2}{5}* 0 -2[/tex]
[tex]5 \leq 0 -2[/tex]
[tex]5 \leq -2[/tex]
This is a false statement.
Option C: (-2,5)
This means
[tex]x=-2[/tex] [tex]y = 5[/tex]
Substitute these values in [tex]y \leq \frac{2}{5}x-2[/tex]
[tex]5 \leq \frac{2}{5}* -2 -2[/tex]
[tex]5 \leq \frac{-4}{5} -2[/tex]
[tex]5 \leq \frac{-4-10}{5}[/tex]
[tex]5 \leq \frac{-14}{5}[/tex]
[tex]5 \leq -2.8[/tex]
This is a false statement.
Option D: (-5,2)
This means
[tex]x=-5[/tex] [tex]y = 2[/tex]
Substitute these values in [tex]y \leq \frac{2}{5}x-2[/tex]
[tex]2 \leq \frac{2}{5}* -5 -2[/tex]
[tex]2 \leq -2 -2[/tex]
[tex]2 \leq -4[/tex]
This is a false statement.
Only option A represents a true statement,
Hence, option A is a solution to the inequality

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

Help me pleaseee (10 points)
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.

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
