Step-by-step explanation:

Using the together rate, it will take more 3.45 days to complete the work.

The together rate is given by the sum of each separate rate.

For this problem, the rates are given as follows:

Hence the amount completed in 2 days is:

2 x (0.1 + 0.0833) = 0.3666.

The amount it would take them to complete 100% of the project working together is found by the together rate as follows:

[tex]\frac{1}{x} = \frac{1}{10} + \frac{1}{12}[/tex]

[tex]\frac{1}{x} = \frac{6 + 5}{60}[/tex]

x = 60/11

x = 5.45 days.

The time it would take to do the remaining 100 - 36.66 = 63.34% of the project is:

0.6334 x 5.45 = 3.45 days.

It will take more 3.45 days to complete the work.

Step-by-step explanation:

5 digit number

5abcd

a = 2 or a = 3. but a = 3 means the upper limit of 53,000. and the sum of digits is 8 and not 21.

so, a = 2.

d = 3n

c = b

5 + a + b + c + d = 21

5 + a + 2b + 3n = 21

a + 2b + 3n = 16

2 + 2b + 3n = 16

2b + 3n = 14

so, n must be an even number to allow an even result (14). therefore, n = 0 or n = 2 (any larger even number n like 4 would not create a single digit result)

if n = 0, then 2b = 14, b = 7

if n = 2, then 2b + 6 = 14, 2b = 8, b = 4

so, we have the options

52770

52446

I suspect that 0 as 0×3 is not considered a multiple of 3 by your teacher, so only n = 2 (or d = 6) is a desired solution.

therefore, I would use

The total capacity of pool in gallons is 1625.

Let us assume the water in the pool be x liters. Forming the equation according as per the statement in question -

x + 300 = 80% of total volume - Equation 1

Forming the equation according to second statement -

30% × x = 300

Since slopes m₁ and m₂ are equal to 5, it shows that these two lines are parallel.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

In Geometry, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts. This ultimately implies that, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m is the slope.

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + b

Given the following equations:

y = 5x + 1

If a function is onto, then its domain can be a set of all non negative real numbers if the function is defined as y = √ x.

It is not necessary that function that is onto should have the domain as non negative real numbers only.
It can also have negative real numbers in its domain.

If the function is of the form:

y = √ x

Then the function will have a domain that is non negative real numbers.

But if function is of the form:

y = x²

Then it can have the domain as all real numbers.

Therefore, we get that, if a function is onto, then its domain can be a set of all non negative real numbers if the function is defined as y = √ x.

The amount invested in the bond with 5% simple interest is $16,666.67

The amount invested in the bond with 6.5% simple interest is $33,333.33  

What is simple interest?

The interest earned under a simple interest arrangement is determined as the amount invested multiplied by the interest rate and the time the investment lasts

I=PRT

let us assume that x was invested in the bond with 5%

interest on x=5%*x=0.05x

amount invested in other bond=50000-x

interest earned on 6.5%=(50000-x)*6.5%

interest earned on 6.5%=3250-0.065x

total interest=0.05x+3250-0.065x

total interest=3250-0.015x

total interest=3000

3000=3250-0.015x

If Henry and Emma want to buy a total of 0.5 yds of fabric and the fabric costs $8.72 per yard then the amount each will pay if they want to split the cost evenly is equal to $2.18.

The amount Henry and Emma will have to pay if they want to split the cost can be calculated by using division.

First, we calculate the cost of 0.5 yards of fabric.

1 yard of fabric cost = $8.72

0.5 yards of fabric cost = x

Here x is the cost of 0.5 yards of fabric

8.72 × 0.5 = x

x = $4.36

As the cost of 0.5 yards of fabric is calculated to be $4.36, the amount each will pay if they want to split the cost evenly can be found by dividing the cost of 0.5 yards by 2.

cost of 0.5 yards of fabric / 2 = 4.36 / 2 = $2.18.

Hence each one of them will pay $2.18 if they want to split the cost evenly.

Given points are (2,-2) and (-3,-1)

Let A(2,-2), B(-3,-1)

We need to calculate the distance between two points.

We know that distance between two points means the length of the line segment that connects two points in the 2D plane.

The formula for finding the distance between the two points A(x₁, y₁),

B(x₂, y₂) in a plane is given by

                                D = √((x₂ - x₁)² + (y₂ - y₁)²)

Now we have two points A(2,-2), B(-3,-1)

By using the above formula we get the distance as

D = √((-3 - 2)² + (-1 - (-2))²)

D = √((-5)² + (-1+2)²)

D = √(25 + (1)²

D = √(25+1)

From the given information, we have that

Quad ABCD. is similar to Quad, EFGH

In the diagram,

Measure of ∠F = 60°

But, ∠B ≅ ∠F

∴ The measure of ∠B = 60°

Measure of ∠H

∠E + ∠F + ∠G + ∠H = 360° (Sum of angles in a quadrilateral)

From the diagram,

m ∠E = 90°

m ∠F = 60°

∠G ≅ ∠C

m ∠C = 75°

∴ m ∠G = 75°

Thus,

90° + 60° + 75° + ∠H = 360°

225° + ∠H = 360°

∠H = 360° - 225°

∠H = 135°
