Answer: $32

Step-by-step explanation:

From the information given in the question, we are told that the ratio of the amount of the student with the most money to the student with the least money was 4:1. If the student with the most money has $128.

This shows that the student with most money has quadruple that is 4× the student with the least money. Therefore, the student will least money will have:

= $128/4

= $32

Answer: No. It's not proportional

Step-by-step explanation:

The direct proportion in mathematics is expressed as:

y = kx

where

y = $200

k = constant

x = $7.50

We then solve for k

y = kx

200 = 7.50k

k = 200/7.50

k = 26.67

Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.

Answer:

i. Yes, Nevan won.

ii. Nevan scored 7464 points.

Step-by-step explanation:

Given: each correct answer = 134 points

           each incorrect answer = -14 points

Since he got 58 questions correctly, then;

His number of points = 134 x 58

                                   = 7772 points

Also, he got 22 incorrect questions, then;

His number of points = -14 x 22

                                   = -308

Nevan's total points = 7772 + (-308)

                                 = 7772 - 308

                                 = 7464

Nevan scored 7464 points.

Nevan won, and also had a total of 7464 points.

Answer:

yes nevan won

Step-by-step explanation:

576Km:6Hrs

576 divided by 6=96 km

6 divided by 6=1

96km:1hr

96 was the coaches speed limit

km=Kilometers

Hrs=Hours

96>90

yes , the coach break the speed limit and the average speed is 96 km ph

Speed is the time rate at which an object is moving along a path

Given,

A coach travels to the beach which is 576 KM away in 6 hours.

The maximum speed he can travel is speed of 90 kph

We need to check whether the coach breaks the speed limit or not.

Yes he has to break the speed limit because in 6 hours with 90kph he can travel only 540 km. He still needs to travel 36 km.

and the average speed he has to maintain is 576/6

96kmph

Hence, yes the coach break the speed limit and the average speed is 96 km ph

The quadratic equation {y = - 16t² + 202.5} correctly represents the given graph.

A quadratic equation is of the form -

f(x) = ax² + bx + c

Given is the graph as shown in the image attached.

The graph given in the image is correctly represented by the quadratic equation -

y = - 16t² + 202.5

Due to the negative coefficient of {a}, it opens downwards. The [y] intercept is at 202.5.

Therefore, the  quadratic equation {y = - 16t² + 202.5} correctly represents the given graph.

Answer:

x = 29/8c

Step-by-step explanation:

2/3(cx+1/2) - 1/4+ 1/4 = 5/2+1/4

2/3(cx+1/2) = 11/4

1/3(cx+1/2) = 11/4 / 2

cx/3 + 1/2/3 = 11/4/2

cx/3 + 1/2*3 = 11/4/2

cx/3 + 1/6 = 11/4/2

cx/3 + 1/6 = 11/4*2

cx/3 + 1/6 = 11/8

cx/3 = 11/8 - 1/6

cx/3 = 29/24

cx = 29/24 * 3

x = 29/8 / c

x = 29/8c

Answer:

Step-by-step explanation:

Given the approximate demand function of night drink expressed as;

p^2+200q^2=177​,

p is the price​ (in dollars) and;

q is the quantity demanded​ (in thousands).

Given

p = $7

q = 800

Required

dq/dp

Differentiating the function implicitly with respect to p shown;

2p + 400d dq/dp = 0

400q dq/dp = -2p

200qdq/dp = -p

dq/dp = -p/100q

substitute p and q into the resulting equation;

dq/dp = -7/100(800)

dq/dp = -7/80000

dq/dp = -0.0000875

This means that the rate of change of quantity demanded with respect to the price is  -0.0000875

5feet by 4/3feet

Step-by-step explanation:

The scale use for a model of kitchen is 1/4 in = 1/2 ft In the model, the kitchen measures 2 1/2 by 2 /3 in. What are actual dimensions of the kitchen.

From the question, we were given the conversation rate of 1/4 in = 1/2 ft In the model,

To get actual dimensions of the kitchen if the kitchen measures 2 1/2 by 2 3 in. Then

✓Let us convert 2 1/2in to feet first= 5/2in as improper fraction.

If 1/4 in = 1/2 ft

5/2in = x ft

Then cross multiply, we have

(5/2×1/2)= 1/4 × X

5/4 = 1/4X

Make X subject of the formula

X= (5/4)/(1/4)

X=5ft.

✓Let us convert 2/3in to feet

If 1/4 in = 1/2 ft

2/3in = x ft

Then cross multiply, we have

1/4×X=2/3×1/2

X=(2/3×1/2)/(1/4)

X=4/3feet

Therefore, the actual dimensions of the kitchen is 5feet by 4/3feet
