The ratio of pens to pencils in Mrs. Bosworth's desk is 4:1. What does this mean?

Answers

Answer 1

pens : pencils = 4 : 1

This means that for every 4 pens there is 1 pencil. Another way to say that is that there are 4 times as many pens as pencils.

Answers

C.)Find the lest common denominator.

Answer:

Step-by-step explanation:

Without multiplying, determine the sign of the product (356,864)(−194,758).
The sign of the product is positive because a positive multiplied by a negative is a positive.
The sign of the product is negative because a positive multiplied by a negative is a negative.
The sign of the product is negative because the second number is negative.
The sign of the product is positive because the first number is positive.

Answers

B. The sign of the product is negative because a positive mutiplied by a negative is a negative

Answer:

The correct option is 2.

Step-by-step explanation:

The given expression is

(356,864)(−194,758)

We need to find the sign of the product (356,864)(−194,758) without multiplying.

Sign of two numbers Sign of product

nadia was offered a job for selling ads cor a magazine. She must agree to one of the following paymen options. CHOICE A:$110 for each ad she sells. CHOICE B:a weekly salary of $150,plis $85 for each ad she sells .Wriye and solve an inequality to determine the number of adds nadia would need to sell per week in order for Choice A to be a better choice

Answers

Let us say that:

x = is the number of ads that Nadia sold every week

P = payment or amount that she receives every week

So the equations we can formulate for choice A and B are:

choice A: P = 110 x

choice B: P = 150 + 85 x

The amount that she receives for A must be greater than she receives for choice B, so:

110 x > 150 + 85 x (inequality equation)

Calculate for x:

110 x – 85 x > 150

25 x > 150

x > 6

Therefore Nadia must sell more than 6 ads every week so that Choice A would be the better choice.

Final answer:

Nadia would need to sell more than 6 ads per week for Choice A to be a better choice than Choice B. We find this by setting up an inequality of 110x > 150 + 85x (where x represents the number of ads sold), then solving for x.

Explanation:

To determine the number of ads Nadia would need to sell per week for Choice A to be a better choice, we can set up the following income inequalities based on her two payment options:

Choice A: $110 per ad sold.

Choice B: $150 weekly salary + $85 per ad sold.

We want to find when Choice A's income exceeds Choice B's income:

Let x be the number of ads sold. Then, the inequality is:

110x > 150 + 85x

To solve for x:

Subtract 85x from both sides: 110x - 85x > 150

This simplifies to: 25x > 150

Divide both sides by 25: x > 6

Therefore, Nadia would need to sell more than 6 ads per week for Choice A to be the better choice.

Solve M=h-w/8 for the variable H

Solve the above equation for W

Solve w=x+y/z for y

Solve the equation above for z

The formula for area of a triangle is A=1/2b solve this equation for B

Solve the equation P=kt/v for the letter K

Answers

1) m = h - w/8

Subtract h from both sides.

m - h = -w/8

Subtract m from both sides.

-h = -m - w/8

Divide all terms by -1.

h = m + w/8.

2) m = h - w/8

Get rid of the denominator 8 by multiplying 8/1 to all terms.

8m = 8h - w

Add w on both sides and subtract 8m from both sides.

w = 8h - 8m

3) w = x + y/z

Get rid of the denominator z by multiplying it to all terms.

wz = xz + y

Subtract xz from both sides of the equation.

wz - xz = y OR y = wz - xz

4) w = x + y/z

Subtract x from both sides.

w - x = y/z

Get rid of the denominator by multiplying it to all terms.

wz - xz = y

Now factor the expression wz - xz.

z(w - x) = y

Divide both sides by w - x.

z = y / w - x

This is read as z equals to y divided by w minus x.

5) The area of a triangle is A = 1/2bh

First, get rid of the denominator by multiplying both sides by 2.

2A = bh

To find b, divide both sides by h.

2A/h = b

6) P = kt/v

Multiply both sides by v.

Pv = kt

Divide both sides by t.

Pv/t = k OR k = Pv/t.

Answer:

Step-by-step explanation:

(1) M = h - [tex]\frac{w}{8}[/tex]

h = M + [tex]\frac{w}{8}[/tex]

(2) M = h - [tex]\frac{w}{8}[/tex]

M - h = -[tex]\frac{w}{8}[/tex]

[tex]\frac{w}{8}[/tex] = h - M

w = 8(h - M)

(3) w = x + [tex]\frac{y}{z}[/tex]

(w-x) = [tex]\frac{y}{z}[/tex]

[tex]\frac{z}{y}[/tex] = [tex]\frac{1}{(w-x)}[/tex]

z = [tex]\frac{y}{w-x}[/tex]

(5) Area of triangle A = [tex]\frac{1}{2}b[/tex]

b = 2A

(6) [tex]P=\frac{kt}{v}[/tex]

⇒ PV = kt

⇒ k = [tex]\frac{PV}{t}[/tex]

How to turn 17/20 into percent

Answers

17/20

multiply top and bottom by 5 ( need to be over 100)

17 x 5 = 85
20 x 5 = 100

85/100 = 0.85

0.85 = 85%

85% is your answer

hope this helps

multiply both denominator and numerator by 5.
20*5=100
17*5=85
then, put the product of the numerator and 5 over the product of the product of the denominator and 5.
85/100.
So, 17/20 as a percent is 85%

What is Algebra?

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

Ryan runs 100 m two times. His times were 14.19 s and 13.78 s.

Daniel runs 100 m two times. His times were 15.77 s and 16.24 s.

The total time taken by Ryan will be

⇒ 14.19 + 13.78

⇒ 27.97 seconds

The total time taken by Daniel will be

⇒ 15.77 + 16.24

⇒ 32.01 seconds

The difference of the Daniel time to Ryan time will be

⇒ 32.01 – 27.97

⇒ 4.04 seconds

Daniel's total time is 4.04 second greater than Ryan's total time.

1. Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 36. How old is each sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.

Answers

let Kim's sisters age be x
then Kim's age= 2x
so when adding both ages you get 36
2x+x=36 i. e 3x=36 (x rep Kim's sisters age)

so x=36/3 = 12
kim sister's age is 12 years
while kim is 2×12= 24years

So because Kim's age is twice the age of her sister an appropriate ratio could be
Kim : Sister 2 : 1
So because you know thier ages are combined to 36 you could divide 36 by 3 which is 12 then you would need to double it for Kim.
So their ages are
Kim- 24
sister- 12

What is the value of n in the equation (n – 4) – 3 = 3 – (2n + 3)?

Answers

n - 4 - 3 = 3 - 2n - 3
n - 4 = 3 - 2n
n = 3 - 2n + 4
n = -2n + 7
n + 2n = 7
3n = 7
n = 7/3

The answer is in bold

(n - 4) - 3 = 3 - (2n + 3)

Let's first start by removing the parenthesis.
(n-4) = +(n-4) so we just remove the parenthesis without changing the signs. So the first part of the equation will be n - 4 - 3.

Before (2n+3), we can notice a minus sign (-) which means that to remove the parenthesis, we need to change the signs of the numbers and variables inside.
-(2n+3) = -2n-3
So the second part of the equation becomes 3 -2n - 3

(n-4) - 3 = 3 - (2n+3)
n - 4 - 3 = 3 - 2n - 3
n - 7 = -2n

Now we need to put the variables apart and the constants apart. So we subtract n from each side:
n - n - 7 = -2n - n
-7 = -3n

Divide both sides by -3
(-7)/(-3) = (-3n)/-3
7/3 = n

In the equation (n-4) - 3 = 3-(2n+3), the value of n is n=7/3

Hope this helps! :)

Laura decides to walk to her job. She walks 1 1/2 miles in 3/5 hour. What is Laura’s walking rate?

Answers

Okay. So, to find the walking rate, we must do 1 1/2 / 3/5. The rule of dividing fractions is keep, Change, flip. 3/2 * 5/3 is 15/6 or 2 1/2 in simplest form. Laura’s walking rate is 2 1/2 miles an hour.

Final answer:

Laura's walking rate is calculated by dividing the distance she walked, 1.5 miles, by the time it took, 0.6 hour. Her walking rate is 2.5 miles per hour.

Explanation:

Laura's walking rate can be calculated by dividing the distance she walked by the time it took. Laura walked 1 1/2 miles in 3/5 hour. To find her rate, we will convert 1 1/2 miles to a decimal, which is 1.5 miles, and we convert 3/5 of an hour to minutes or hours in decimal form. Since 3/5 of an hour is the same as 36 minutes (because 60 minutes * 3/5 = 36), we can calculate Laura's walking rate.

To find the rate, we use the formula:

Rate = Distance ÷ Time

So Laura's walking rate is:

Rate = 1.5 miles ÷ 0.6 hour

Rate = 2.5 miles per hour (since 1.5 ÷ 0.6 = 2.5)

Therefore, Laura walks at a rate of 2.5 miles per hour.
