Answer 1
-9 is the answer :))))))))))))))
Answer 2

Answer: -9/1

Step-by-step explanation:

first covert 5 and 1/4 into an improper fraction

5x4 ( 5 one quaters)  = 20 + the 1 remaining = 21

so 21/4

or 21 quaters

then divide .

but remeber these rules!

If the signs are the same (either both positive or both negative), then the answer is positive.

If the signs are different (one negative and one positive), the answer is negative.

so , our answer will be a negative

then

divide as usual

but when we divide we need to remeber to x by the reciprocal of our divisor

the divisor here is - 7/12

We can think of a whole number as being "number/1", so the reciprocal is just like "flipping it over"

-7/12  "flipping it over" is -12/7

so three rules

1- our answer will be negative

2- we are timesing by the reciprocal

FINAL ANSWER =

21/4 x -12/7

21 x 12 = 252

4 x7= 28

- 252/ 28 is the answer

Find the GCD (or HCF) of numerator and denominator

GCD of 252 and 28 is 28

Divide both the numerator and denominator by the GCD

252 ÷ 28

28 ÷ 28

Reduced fraction:  

9

1

Therefore, 252/28 simplified to lowest terms is -9/1.

if the perimeter of the blanket has to be at least 280 inches is there egnough room for all three of them to cuddle up under the blanket? ( she’s talking about her dogs)

Answers

Answer:

hope it helps

Step-by-step explanation:

angle < EDG = 90°

5x + 4x = 90

9x = 90

x = 90/9

x = 10°

which means

5x = 50°

4x = 40°

---------------------------

sice EF and DG are parallel lines

EHD = 40°

DHG is 90°

then HGD = 50°

-----------------------------------------

ED = 64 x2 (2 sides) = 128 inches

DG = 84 x2 (2 sides) = 168 inches

total perimeter = 128 + 168 = 296 inches

and yes. theres enough room for all 3 to cuddle

the sum of 12 times a number, n, and 4 is no more than 190. What are all the possible values of the number?

Answers

Answer:

{n:n≤15.5}

Step-by-step explanation:

√First derive the inequality from interpreting the statement,thus 12n+4≤190

√Second, solve the derived inequality ( ie.make n the subject)

√Finally, you'll arrive at the answer as n≤15.5

Therefore the possible values of the variable n is all numbers less than or equal to 15.5

PROOF

For n greater than 15.5

Let's take n to be 20

Therefore from the derived inequality

12n+4≤190

12(20)+4 = 240

Here,240 is greater than 190

Since for n≥15.5 will not satisfy the inequality n≠all numbers more than 15.5

Answers

M is the slope B is the y-intercept

The lights which were on was 48%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100.

Given that there were 72 lights on, and 78 lights turned off.

We need to find the percent of the lights turned on.

So, percentage of something =

= number of thing / total number of the thing x 100%

Here, the number of thing = light on = 72

Total = 72 + 78 = 150

So, the percent of light on = 72 / 150 x 100% = 0.48 x 100%

= 48%

Hence the lights which were on was 48%.

Solve by using substitution
8x - 10y = 4
x = 8

Answers

Answer:

y= 6

Step-by-step explanation:

First you substitute in the 8 for x. you then multiply 8 times 8 which equals 64. you subtract 64 from 4 and 64, since it would be the opposite of addition. you would then take the -10y=-60, and you would divide by negative 10 to get y by itself. since negative 60 divided by negative 10 is a positive 6, your answer would be y equals 6.

One number is 5 less than twice a number.if the sum of two numbers is 76 what is the smaller number ?

Answers

Answer:

the smaller number is 27.

Step-by-step explanation:

set two numbers are a and b

one number is less that twice of a number:

let's say a is 5 less than twice of b

so we have : a=2b-5

sum of the two numbers is 76: we have a+b=76

then we set up the system of equation[tex]\left \{ {{a=2b-5} \atop {a+b=76}} \right.[/tex]

substitude a = 2b - 5 into the second equation

we have,

2b - 5 + b = 76

3b - 5 = 76

3b = 81

b = 27

Since a + b = 76 so a = 49

Dalco Manufacturing estimates that its weekly profit, P, in hundreds of dollars, can be approximated by the
formula P = -4x² + 8x + 3, where x is the number of units produced per week, in thousands.
How many units should the company produce per week to earn the maximum profit?
Find the maximum weekly profit.
a.
b.

Answers

P = -2x^2 + 8x + 2

for maximum P, dP/dx = 0

dP/dx = -4x + 8 = 0

4x = 8

x = 2

The company should produce 2,000 units per week to earn maximum profit.

Maximum profit = -2(2)^2 + 8(2) + 2 = -8 + 16 + 2 = 10

Therefore, the maximum weekly profit is $1,000.
