Answers

Answer:

2

Step-by-step explanation:

you can make it like this

(1/4)^ x=1/16

so x=2

x = 2
This is because when you have a negative exponent like -x to rearrange it to a fraction and change the negative to a positive.
So 4^x would be the denominator and 1 would be the numerator.
So 1 / 4^x = 1 / 16
To achieve 16 from 4 you square it, therefore x = 2

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

Answers

Answer:

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

Each correct answer is worth 134 points, and each incorrect answer is worth −14 points. If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?

Answers

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.

Step-by-step explanation:

A nightclub has approximated the demand for their Thursday night drink special by p^2+200q^2=177​, where p is the price​ (in dollars) and q is the quantity demanded​ (in thousands). Find and interpret when the price is ​$ 7 and the demand is 800 drinks.

Answers

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

I just need some quick help with this. Distributive properties aren't my best section.
Describe how you would use the distributive property to simplify (39x5).

Answers

In this case u can’t use the distributive property. U just multiple whats in the parenthesis (39•5)=195 and that’s ur answer.
Let’s say if the problem said 5(2+1) u can’t use the distributive property bc u have to do what’s in the parentheses first. 5(3)=15
But If u had a problem like 2(4x+6) then u can use the distributive property. This is bc u can’t add 4x+6 bc they aren’t like terms. So u multiple the 2 by 4x which is 8x and the 2 by 6 which is 12 then ur answer would be : 8x+12

Mary is painting pumpkins to earn money. She plans on selling each pumpkin for $7.50. She currently has $200 in her savings account. Is the amount of money in her bank account proportional to the number of pumpkin she sells?

Answers

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.
