Blake can paint a room in 9 hours, Ned can paint the same room in 6 hours, how long to paint the room together

Answers

Answer 1
Work done by Blake = 1/9; Work done by Ned = 1/6; Total work done by both of them together is given by 1/6 +1/6 = 3+2/18 = 5/18; So, the time taken by both of them if they work together is given by: 18/5 =3 3/5 hours.

Ms. Jaffey had a total of 428.5 ounces of pretzels to put into 5 bowls for a party. She put an equal number of ounces of pretzels into each bowl. How many ounces of pretzels did Ms. Jaffey put into each bowl?

Answers

Multiply the 2 numbers and see what you get

Ms. Jaffey put approximately 85.7 ounces of pretzels into each bowl.

To find out how many ounces of pretzels Ms. Jaffey put into each bowl, we need to divide the total number of ounces by the number of bowls.

Ms. Jaffey had a total of 428.5 ounces of pretzels, and she distributed them equally among 5 bowls. Therefore, we can divide the total number of ounces by 5 to determine the amount in each bowl.

428.5 ounces ÷ 5 bowls = 85.7 ounces.

So, Ms. Jaffey put approximately 85.7 ounces of pretzels into each bowl.

Since it's unlikely to have exact measurements when dividing a total quantity into equal parts, we round the result to one decimal place, giving us 85.7 ounces. This means that each bowl contains approximately 85.7 ounces of pretzels.

A cable TV/Internet/phone provider charges new customers $90 for all three services, per month, for the first year
under their 90 NOW promotion. Alice normally pays $59 for her monthly home phone service, $49 for Internet
service, and $69 for cable television
1. What are her percent savings if she switches to the 90 NOW plan? Round to the nearest percent.

Answers

Answer:

49%

Step-by-step explanation:

First find how much Alice is paying for the all three service currently.

Amount paid by Alice at present= 59 +  49 + 69 = $ 177

If she switches to 90 NOW plan, then the amount saved = 177 - 90 = $ 87

Percentage of savings = (saved amount ÷ total amount she was paying at present) * 100

          [tex]= \frac{87}{177}* 100\\\\= 49.15[/tex]

          = 49 %

What is the slope of the line that passes through the points (-5, -7)(−5,−7) and (4, -1) (4,−1)

Answers

Answer:

2/3

Step-by-step explanation:

REmember that the slope of a line is y/x. To find this, we must use the formula:

y2-y1/x2-x1=y/x

So this is -1 - -7/4- -5. The  -1 -- 7 is actually -1+7. This is 6, meaning y equals 6.

The x is 4 - - 5 is actually 4+5. This is 9, meaning x is equal to 9.

We can now write this as y/x. This would be 6/9.

Once we simplfy this, we get 2/3.

Find the exact (leave pi) and the approximate ( pi = 3.14 ) circumference for each circle
(#s A-F ONLY)

Answers

Answer/Step-by-step explanation:

a. Circumference (C) = πd

d = 12 cm

π = 3.14

Exact value of C = π*12 = 12π cm

Approximate value of C = 12*3.14 = 37.68 cm

b. Circumference (C) = πd

d = 8 m

π = 3.14

Exact value of C = π*8 = 8π m

Approximate value of C = 8*3.14 = 25.12 m

c. Circumference (C) = πd

d = 6 km

π = 3.14

Exact value of C = π*6 = 6π km

Approximate value of C = 6*3.14 = 18.84 km

d. Circumference = πd

d = 9 ft

π = 22/7

Exact value of C = π*9 = 9π ft

Approximate value of C = 9*22/7 = 28.2857143 ≈ 28.29 ft (nearest hundredth)

e. Circumference = 2πr

r = 4 mm

π = 22/7

Exact value of C = 2*π*4 = 8π mm

Approximate value of C = 2*22/7*4 = 25.1428571 ≈ 25.14 mm (nearest hundredth)

f. Circumference = 2πr

r = 7 mi

π = 22/7

Exact value of C = 2*π*7 = 14π mi

Approximate value of C = 2*22/7*7 = 44 mi (nearest hundredth)

What is the unit rate for the ratio 4/7: 8/21?

Answers

Answer:

The unit rate is 1.5

Step-by-step explanation:

Given

[tex]Ratio = 4/7 : 8/21[/tex]

Required

Determine the unit rate

To do this, we need to express the ratio as:

[tex]Ratio = m : 1[/tex]

Where m is the unit rate

[tex]Ratio = 4/7 : 8/21[/tex]

Express as fraction

[tex]Ratio = \frac{4/7 }{ 8/21}[/tex]

Solve

[tex]Ratio = \frac{4}{7} * \frac{21}{8}[/tex]

[tex]Ratio = 1.5[/tex]

Express as ratio

[tex]Ratio = 1.5 : 1[/tex]

Hence, the unit rate is 1.5

MIDDLE SCHOOL MATH On the subway 8 out of 10 people are carrying a briefcase. Based on this information, if there are 700 people on the subway, then about how many do NOT have a briefcase?

Answers

Answer:

140

Step-by-step explanation:

If 8 out of 10 are carrying a briefcase, that means 2 out of 10 are not carrying one.

Use a proportion to find how many don't have a briefcase with 700 people

Let x represent the number of people without a briefcase:

[tex]\frac{2}{10}[/tex] = [tex]\frac{x}{700}[/tex]

Cross multiply and solve for x

10x = 1400

x = 140

So, 140 people do not have a briefcase

Answer:

140

Step-by-step explanation:

8/10 people, there's 700 people

10 multiplied by 70 =700.

Spinner ; (red, green, blue, yellow or black)

Even numbers = (2, 4, 6)

Probability of obtaining an even number on rollin g a fair cube :

Probability = required outcome / Total possible outcomes

P(even number) = 3 /6 = 1/2

A circular mirror has a diameter of 12 inches. And a circular frame that is 3 inches wide surrounds the mirror. What is the combined area, in square inches, of the circular mirror and the frame? *

Answers

Answer:

254.5 in.^2

Step-by-step explanation:

diameter of mirror = 12 in.

radius of mirror = diameter/2 = 13 in. / 2 = 6 in.

frame width = 3 in.

radius if combined mirror and frame = 6 in. + 3 in. = 9 in.

A = (pi)(r^2)

A = 3.14159 * (9 in.)^2

A = 3.14159 * 81 in.^2
