Answer:
False
Step-by-step explanation:
A checkout clerk at a department store is expected to complete 16 transactions every hour
I.e 16 transactions in 60 minutes
So if it's 6 transactions, let's check to know if the minutes Tally.
16 = 60
6 = (6*60)16
6 = 22.5 minutes
But in the statement it was 20 minutes, so the answer is false.
There are 3 boys in a Class of 11 student
What ratio of all student in the class of girls?

It takes 48 minutes for 7 people to paint 7 walls. How many minutes does it take 20 people to paint 20 walls?
Answer: 48 minutes
Step-by-step explanation:
If there are 7 people painting 7 walls, we can assume that 1 person is painting 1 wall. Altogether they can each paint in 48 minutes.
If there are 20 people painting 20 walls, it would also equal 48 minutes because each person can paint in that time.
Answer:
137 minutes.
2 hrs and 17 minutes
Step-by-step explanation:
The painting of each wall takes 6.85 minutes.
48 / 7 = 6.85.
therefore if there are 20 walls, it must take 20 people 2 hrs and 17 mins
20 x 6.85 = 137minutes.

Explanation:
Starting at (4, -1) and moving four units up will have us arrive at (4, 3). We add 4 to the y coordinate and keep the x coordinate the same. The algebraic rule is stated as [tex](x,y) \to (x,y+4)[/tex].
Next, we reflect over the y axis. This will have us flip the sign of the x coordinate while keeping the y coordinate the same. The algebraic rule for this kind of reflection is [tex](x,y) \to (-x,y)[/tex]. The point (4,3) reflects over the y axis to get to (-4,3)
So we started at (4, -1), then moved four units up to get to (4,3) and then reflected over the y axis to get to (-4, 3) which is the final stop.
This is all shown in the diagram below.
Can someone please help me with this two please
Answer:
1. B
2. C
Step-by-step explanation:
1. In this, we already know one side and one angle are congruent. For the triangles to be congruent by SAS, another side is necessary. Thus CB = FE
2. Here, we see that one set of sides are congruent. We see another set of angles are congruent as well. We also know that the center angle is congruent as the angles are formed by two straight lines intersecting. Since we see 2 next door angles and the side beside it congruent, they are proven congruent by AAS.
The base of an isosceles triangle is 4/5. The perimeter of the triangle is 4\2\15 what is the length of either of the remaining equal sides
Answer:
1 2/3
Step-by-step explanation:
Assuming you mean the perimeter is 4 2/15, the sum of the lengths of the two equal sides is ...
4 2/15 - 4/5 = 4 2/15 - 12/15 = 4 -10/15
Then either of the remaining sides is half this value, or ...
(4 -10/15)/2 = (4/2) -(1/2)(10/15) = 2 -5/15 = 1 10/15 = 1 2/3
Each of the remaining sides has length 1 2/3.

A recipe requires 1/3 cup of sugar for every 3/4 cup of flour. How many cups of sugar are required for every cup of flour?
Answer:
4/9 cup of sugar
Step-by-step explanation:
[tex]\frac{1}{3} cup of sugar= \frac{3}{4} cup of flour[/tex]
[tex]? cup of sugar=1 cup of flour[/tex]
so crisscross them and finally you'll get
1/3*4/3=4/9
For 1 cup of flour, 4/9 cups of sugar is needed.
What are ratios and proportion?Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other. A statement expressing the equality of two ratios A:B and C:D is called a proportion. We can express proportion as -
A : B ∷ C : D
AND
A x D = B x C
Product of extremes equal to product of means.
Given is a recipe that requires 1/3 cup of sugar for every 3/4 cup of flour.
Now -
For 1/3 cup of sugar = 3/4 cup of flour is needed.
For 1 cup of flour = (1/3)/(3/4) cups of sugar = 1/3 x 4/3 = 4/9 cups of sugar is needed.
Therefore, for 1 cup of flour, 4/9 cups of sugar is needed.

The circumference of the hub cap of a tire is 76.87 centimeters. Find the area of this hub cap. Use 3.14 for pi. Use pencil and paper. If the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.
The area of this hub cap is about
blank square centimeters.
Answer: The area of this hub cap is about 470.46 square centimeters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Circumference (C) = 2π radiusReplacing with the values given:
76.87 = 2 (3.14) r
Solving for r (radius)
76.87/ (2x 3.14) =r
r = 12.24 cm
To find the Area:
Area of a circle = π r^2A = 3.14 (12.24)^2
A = 470.46 cm2
If the circumference of the hub is smaller, the area is also smaller because it means that the radius of the circle decreases.

The midpoint of is point P at (−16,6). If point A is at (−10,8), what are the coordinates of point B? (−42,20) (−22,4) (−13,7) (2,−5)
Answer:
B (-22 , 4)
Step-by-step explanation:
-16=(-10+x)/2
*2 *2
-10+x=-32
+10 +10
x=-22
6=(8+y)/2
*2 *2
12=8+y
-8 -8
4=y
so B(-22, 4)
The coordinates of point B is (-22, 4).
What are the Coordinates?Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.
If we have the end points (x', y') and (x'', y'').
The mid point is ((x' + x'')/2, (y' + y'')/2).
Given that one of the end point A is at (-10, 8).
The mid point is at P(-16, 6).
Let the other point be B(x, y).
(-10 + x) / 2 = -16 and (8 + y) / 2 = 6
(-10 + x) / 2 = -16
⇒ -10 + x = -32
⇒ x = -32 + 10
⇒ x = -22
(8 + y) / 2 = 6
8 + y = 12
y = 12 - 8
y = 4
Hence the coordinate of the other point is B(-22, 4).
