For time-speed-distance problems, you use the relationship
.. speed = distance/time
in any of its various forms.

The distance traveled at A mph is
.. distance = speed * time
.. distance = A*3

The time required for the rest of the journey is
.. time = distance / speed
.. time = (C -3A)/B

The the total time required to travel C miles is the 3 hours for the first part plus the time for the rest of the journey.
.. total journey time = 3 + (C -3A)B . . . . . hours

Cara earns a base pay of $1,800 per month at a car dealership plus a commission of 6% of her sales. What are Cara’s total earnin
k0ka [10]

Cara’s total earnings in a month in which she sells $40,000 worth of merchandise is $ 4200

<h3><u>Solution:</u></h3>

Given that Cara earns a base pay of $1,800 per month at a car dealership plus a commission of 6% of her sales

Let us first calculate commission earned from selling $40,000 worth of merchandise

commission earned from selling $40,000 = 6 % of $ 40,000

\text {commission earned from selling } \$ 40,000=\frac{6}{100} \times 40,000

\text {commission earned from selling } \$ 40,000=2400

Also given that Cara earns a base pay of $ 1800 per month

So Cara’s total earnings in a month in which she sells $40,000 worth of merchandise is calculated by adding commission earned $ 2400 to base pay $ 1800 per month

<em>Cara’s total earnings in a month = base pay + commission earned</em>

Cara’s total earnings in a month = $ 1800 + $ 2400 = $ 4200

Thus the total earning of Cara in that month is $ 4200

Are rectangles ABCD and WXYZ congruent? Why or why not? Yes, all right angles were preserved. Yes, both rectangles have an area
Setler79 [48]

Answer:

D. No, there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.

Step-by-step explanation:

Two figures are congruent if their vertices can be mapped into one another by appropriate rigid transformation or combination of rigid transformations. Examples of the transformation are; reflection, dilation, rotation and translation.

Comparing the two figures, it would be observed that they are not congruent. Since there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.

Carlos and Maria drove a total of 233 miles in 4.4 hours. Carlos drove the first part of the trip and averaged 55 miles per hour
11Alexandr11 [23.1K]
So basically
D=RT
distance=rate times time

D=233
carlos speed=55
maria speed=50
total time=4.4 hours

so therefor we have to represent
carlos time
maria time
carlos distance
maria dstance

let's say that
remember that whatever carlost drove is 233 minus maria (time and distance)
and since we are solving for maria time and distnace, solve in terms of them
maria time=t
maria distance=d
carlos time=4.4-t
carlos distance=233-d

remember total D=RT
find their seperate equations
carlos
233-d=55(4.4-t)

maria
d=50(t)
use them to solve

233-d=55(4.4-t)
subsitute 50(t) for d
233-50t=55(4.4-t)
add 50t to both sides
233=55(4.4-t)+50t
distribute using distributiver protperty (a(b+c)=ab+ac)
55(4.4-t)=242-55t
233=242-55t+50t
add like terms
233=242-5t
add 5t to both sides
233+5t=242
subtract 233 from both sides
5t=9
divdie both sides by 5
t=1.8
maria drove 1.8 hours

the answer is A
