Bob the builder is making 540 kg of concrete mix.
Concrete is made by mixing cement, sand and gravel in the ratio 1:3:5
How much gravel does he need?

Answers

Answer 1

Answer:

300 kg

Step-by-step explanation:

Let Constant Ratio be x:

x+3x+5x = 540

9x = 540

x = 60 kg

So, weight of gravel (W) = 5x

5 x 60

W = 300 kg (ANS)

Pete can do a job in 50 minutes while his brother Jim can do it in 1/2 the time. How long will it take them to do the job working together? (50/3 min)

Answers

It will take them 20 minutes to do the job working together.

Working time calculation

Given that Pete can do a job in 50 minutes while his brother Jim can do it in 1/2 the time, to determine how long it will take them to do the job working together, the following calculation must be performed:

1/1 + 2/1 = 3/11 / (3/1) = 1/360 min / 3 = 20 min

Therefore, it will take them 20 minutes to do the job working together.

The price of a cd was decreased by 2% to £14. What was the price before the decrease?
Give your answer to the nearest penny.

Answers

Answer:

14.28

Step-by-step explanation:

2% of 14 is .28

.28 + 14 = 14.28

Hi!

Since the price was decreased by 2%, that means that 14 is 98% (100% - 2%) of the original price. So, we just have to figure out 98% of what number is 14.

98% can be written in decimal form as 0.98.

We can set up the following equation:

14 = 0.98x

Now, divide both sides by 0.98:

14/0.98 = 14.2857143

The question says to round to the nearest penny, so your answer is

You are renting a beach house for the summer. The cost of renting the beach house plus the one-time security deposit is represented by the equation y = 151x + 575 , where represents the number of days that the beach house is rented and y is the total cost of the rental. What is the cost of the security deposit ?

Will mark the brainliest!

Please someone explain this to me. Needs to be tonight!

Answers

Answer:

The one-time security deposit is just 575, if you add it to the cost of renting the beach house, you then get y, which is the total cost of everything. haha, its logical.

so,

The one-time security deposit is just 575.

and

The cost of renting the beach house is 151x.

while

The total cost of the rental is y, i.e 151x + 575.

Answer:

575

Step-by-step explanation:

The answer is included in the question already

The cost of renting = security deposit + rental per day

y - is total cost of rentingOne off security deposit = 575Rental cost = 151 per day

So the answer is 575

The back of Alisha's property is a creek. Alisha would like to enclose a rectangular area, using the creek as one side and fencing for the other three sides, to create a pasture. If there is 380 feet of fencing available, what is the maximum possible area of the pasture?

Answers

9514 1404 393

Answer:

  18050 square feet

Step-by-step explanation:

Let x represent the length of fence parallel to the creek. Then the remaining 380-x feet of fence is divided between the two ends of the pasture. The area will be the product ...

  A = (x)(1/2)(380 -x)

The graph of this is a parabola that opens downward. It has x-intercepts at x=0 and x=380. The vertex (maximum) will be on the line of symmetry, halfway between these zeros, at x = (0 +380)/2 = 190.

Then the area is ...

  A = (190 ft)(1/2)(380 -190 ft) = (190 ft²)/2 = 18,050 ft²

The maximum possible area of the pasture is 18,050 square feet.

A line is drawn parallel to y = x. It has the same slope, so it’s equation has the form y = x + b. The new line passed through the point (2, 5). What is its y- intercept (b)?

b = 3

Step-by-step explanation:

(2,5) is information! x = 2 and y = 5.

Use these values in the equation:

y = x + b

5 = 2 + b

Subtract 2.

3 = b

The equation of the line is y = x + 3.

Step-by-step explanation:

By using geometry to evaluate the given integral, the value is equal to 6 units.

How to use geometry to evaluate an integral?

In order to use a geometry to evaluate a definite integral, you should identify the portion of a graph which corresponds to the given integral.

Also, you'll mark out the geometric shapes that are formed on the graph, so as to enable you calculate their areas. Finally, you'll add the areas together.

From the graph of the integral shown in the image attached below, the geometric shapes that are formed are rectangle and triangles.

For the area of rectangle, we have:

Area of rectangle = L × B

Area of rectangle = 2 × 2

Area of rectangle = 4 units.

For the area of triangle, we have:

Area of triangle = 1/2 × b × h

Area of triangle = 1/2 × 2 × 2

Area of triangle = 2 units.

Total area = 4 + 2

Total area = 6 units.

Arthur has decided to start saving for a new computer. His money is currently in a piggy bank at home, modeled by the function s(x) = 85. He was told that he could do the laundry for the house and his allowance would be a(x) = 10(x − 1), where x is measured in weeks. Explain to Arthur how he can create a function that combines the two and describe any simplification that can be done.

Answers

Answer:

Two or more independent functions (say f(x) and g(x)) can be combined to generate a new function (say g(x)) using any of the following approach.

h(x) = f(x) + g(x)h(x)=f(x)+g(x) h(x) = f(x) - g(x)h(x)=f(x)−g(x)

h(x) = \frac{f(x)}{g(x)}h(x)=

g(x)

f(x)

h(x) = f(g(x))h(x)=f(g(x))

And many more.

The approach or formula to use depends on the question.

In this case, the combined function is:

f(x) = 75+ 10xf(x)=75+10x

The savings function is given as

s(x) = 85s(x)=85

The allowance function is given as:

a(x) = 10(x - 1)a(x)=10(x−1)

The new function that combined his savings and his allowances is calculated as:

f(x) = s(x) + a(x)f(x)=s(x)+a(x)

Substitute values for s(x) and a(x)

f(x) = 85 + 10(x - 1)f(x)=85+10(x−1)

Open bracket

f(x) = 85 + 10x - 10f(x)=85+10x−10

Collect like terms

mark as brainiest

f(x) = 85 - 10+ 10xf(x)=85−10+10x

f(x) = 75+ 10xf(x)=75+10x

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To determine which option would result in the greatest payday at the end of the first month of employment, let's calculate the total amount for each option:

a)

Lump sum of $1,500,000

The total amount is $1,500,000.

b)

$50,000 initially and $100,000 perday for the next 30 days

The total amount is $50,000 (initial) + $100,000/day * 30 days

T = $50,000 + $3,000,000

On simplifying the equation , we get

T = $3,050,000

Hence , receiving $50,000 initially and $100,000 per day for the next 30 days would result in greater payday

Answer:

Step-by-step explanation:

The curve is maybe a bit easier to visualize if you write it as x = 4sin(y). The area is

∫[0,π/2] (4-x) dy

= ∫[0,π/2] (4-4sin(y)) dy = 2π-4

∫4-4sin(y) dy = 4y + 4cos(y)

This is a bit easier than using vertical strips, where the area is

∫[0,4] arcsin(x/4) dx

since integrating arcsin(x/4) involves integration by parts.

u = arcsin(x/4)

du = 1/√(16-x^2) dx

dv = dx

v = x

∫arcsin(x/4) dx

= x arcsin(x/4) - ∫x/√(16-x^2) dx
