Henry can paint a small house in 3 days, Ruby can paint a small house in 4 days, and Charlie can paint a small house in 5 days. How long will it take for Henry, Ruby and Charlie to paint one small house together? Give your answer as a fraction.

Answers

Answer 1

Answer:

So it will take them 1 day 6 hours and 39 minutes to paint one small house.

Step-by-step explanation:

Henry can paint 1 small house in 3 days so he can paint 1/3 or .3333 in a day

Ruby can paint 1 small house in 4 days so she can paint 1/4 or .25 in a day

Charlie can paint 1 small house in 5 days so he can paint 1/5 or .2 in a day

Together, that means they pain .3333 + .25 + .2 of a house per day. That's an daily rate of:

.3333 + .25 + .2 = .78333

The portion of the house they clean in x days is .78333x. We'd like to know how long it will take them to paint 100% or 1 of the house. So:

.78333x = 1   Divide each side by .78333

x = 1/.78333

x ≈ 1.277

Let's convert .277 to hours by multiplying by 24

.277 * 24 = 6.65

Let's convert .65 to minutes by multiplying by 60

.65 * 60 = 39

So it will take them 1 day 6 hours and 39 minutes to paint one small house.

Answer 2

Answer:

1.277 days

Step-by-step explanation:

H paint .3333 a day  R paint .25 a day  Charlie paint .2 a day

.3333 + .25 + .2 = .78333

x is number of days to paint.

.78333x = 1  

x = 1/.78333  = 1.277

 1.277 days

Juvi is baking oatmeal raisin cookies and fudge brownies! To make 4 batches of brownies, Juvi needs 2/3 of a cup of sugar. She already has 1/2 of a cup of sugar in her cabinet and her sister Evi brings her 2/5 of a cup of sugar when she hears she needs more! Will Juvi have enough sugar to make 4 batches of brownies? If she does not have enough, how much more does she need? Explain below.**PLEAE HELP WILL MARK BRAINLIEST.

Answers

We can add the fractions together to compare with how much sugar she needs.

[tex]\frac{1}{2}+\frac{2}{5}=\frac{5}{10}+\frac{4}{5}=\frac{9}{10}[/tex]

So Juvi has [tex]\frac{9}{10}[/tex] cups of sugar.

She needs [tex]\frac{2}{3}[/tex] cups, so let's make the denominators the same and compare.

[tex]\frac{2}{3}=\frac{20}{30}[/tex]

[tex]\frac{9}{10}=\frac{27}{30}[/tex]

Since [tex]\frac{27}{30}[/tex] > [tex]\frac{20}{30}[/tex], she has enough sugar to make 4 batches of brownies.

Hope this helps.

the price of a shirt is increased by 10%. later the price is reduced in a sale by 10%, is the sale price more, less or the same as it was at the start? give reasons for your answer

Answers

Answer:

less

Step-by-step explanation:

We assume price of a shirt is $100.

Initially price is increased by 10%: 100+10=110

Then it is reduced by 10%: 110-11=99

Now price of a shirt is $99.

Answer is price of a shirt is less than it was at the start.

The functions y=x2+cx2 are all solutions of equation: xy′+2y=4x2, (x>0). Find the constant c which produces a solution which also satisfies the initial condition y(10)=2.

Answers

Answer: c = -0.98

Step-by-step explanation: Differential equation of first order is an equation involving differentiable function and its derivative.

For the differential equation: [tex]xy' +2y=4x^{2}[/tex], it given a solution function:

[tex]y=x^{2}+cx^{2}[/tex]

Factorating the function: [tex]y=x^{2}(1+c)[/tex]

So, to determine constant c, use the initial condition:

When x = 10, y = 2:

[tex]2=10^{2}(1+c)[/tex]

[tex]1+c=\frac{2}{100}[/tex]

[tex]1+c=0.02[/tex]

c = -0.98

Constant c that satisfies the initial condition is c = -0.98

Answer:

s = 120

r = 33

t = 33

Step-by-step explanation:

You are solving for the variables r & t & s. Note that it is given that the two parallelograms are congruent with each other.

Make sure that they are facing the same way. Note that DC ≅ GH, AD ≅HE, FE ≅ AB

Solve:

DC ≅ GH; 70 = s - 50

Isolate the variable, note the equal sign, what you do to one side, you do to the other. Add 50 to both sides;

70 (+50) = s - 50 (+50)

s = 70 + 50

s = 120

Solve:

AD ≅ HE

2r = 66

Isolate the variable, divide 2 from both sides:

(2r)/2 = (66)/2

r = 66/2

r = 33

Solve:

FE ≅ AB

t + 50 = 83

Isolate the variable, subtract 50 from both sides:

t + 50 (-50) = 83 (-50)

t = 83 - 50

t = 33

A rectangular parking lot has a length that is 10 yards greater than the width. The area of the parking lot is 600 square yards. Find the length and the width

Answers

Step-by-step explanation:

Let x be the width of the parking lot. Then (x + 10) is the length of the parking lot.

x(x + 10) = 600

x^2 + 10x = 600

x^2 + 10x - 600 = 0

(x+30)(x-20) = 0

x = 20 or x = -30 (rejected as x must be positive)

Hence the length is 30 yards and the width is 20 yards.

Ajar contains 6 pennies, 14 nickels, 16 dimes and 4 quarters. If one coin is
chosen at random, find P(nickel or dime) as a simplified fraction. You may
use the standard keyboard or Equatio to type the fraction. *

Answers

Answer:

P(nickel or dime) = 3/4

Step-by-step explanation:

First, find the total amount of coins that there are:

6 + 14 + 16 + 4 = (20) + (20) = 40

You are trying to find P(nickel or dime). Note that there are 14 nickels, and 16 dimes. Add these two numbers together:

P(Nickel or dime) = (14 + 16)/40

P(Nickel or dime) = (30)/40

Simplify. Divide common factors from both the numerator & denominator (10)

P(Nickel or dime) = (30/40)/(10/10) = 3/4

P(nickel or dime) = 3/4

~

p(nickle or dime) = 3/4

What are ratios and proportions?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.

The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that the points C, D, E and F all lie on the same line segment, in that order, such that the ratio of CD: DE: EF is equal to 3 : 2: 6. If CF = 11. The value of DF will be calculated as below:-

3x + 2x + 6x = 11

11x = 11

x =1

DF = 2x + 6x

DF = 2 + 6

DF = 8

Therefore, the value of segment DF will be 8 units.

Answer:

Step-by-step explanation:

Order of operations. What's in the parenthesis is first.

4 + 3 ( 7+4 x 2) - 100  

Concentrate on (7 + 4 x 2 ) first.

We multiply first so 4 x 2 = 8  then we add.

(7 + 8) = 15

4 + 3(15) - 100    Again, we multiply first.

4 + 45 - 100      Now we can add and subtract in any order.

49 - 100 = - 51

A term is a single mathematical expression. It may be a single number (positive or negative), a single variable (a letter), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.

So the terms are 9a, 4b, and 18.

not a hundred percent sure since there are no graphs attached but mine was Graph 1 to be the answer

After 2 years she will have earned $12 * 2*2.3% = $12* 4.6% = 55c interest (to the nearest cent). Therefore the balance will be $12.55

After 6 years she will have earned $12 * 6*2.3% = $12* 13.8% = $1.66 interest (to the nearest cent).  

Therefore the balance will be $13.66

After 10 years she will have earned $12 * 10*2.3% = $12* 23% = $2.76 interest (to the nearest cent).  

Therefore the balance will be $14.76
