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?
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)
2(3x-4)=3x+1
I just need help solving this-
Answer:
x=3
Step-by-step explanation:

a person buys a washing machine in the condition that he shall pay sum of INR 5880 at the cash down payment and the same sum at the end of the first year and two years. what is the total interest paid by him in this scheme, if the rate of interest is 5% compounded yearly?
Answer: $827
Step-by-step explanation:
Given that :
Cash down payment = 5880
Payment at end of first year = 5880
Payment at end of second year = 5880
Interest rate = 5% = 0.05 compounded yearly
Let purchase amount = y
Amount left after cash down = amount on which interest is paid = y - 5880
Interest at end of first year :
(y - 5880) * 0.05 = 0.05y - 294
Amount to pay plus interest :
Amount left after cash down payment - amount paid at end of first year + interest
y - 5880 - 5880 + 0.05y - 294
y - 12054 + 0.05y
= 1.05y - 12054
2nd year interest :
(1.05y - 12054) * 0.05
= 0.0525y - 602.7
Amount left + interest = 2nd year payment
(1.05y - 12054) + (0.0525y - 602.7) = 5880
1.1025y - 12656.7 = 5880
1.1025y = 5880 + 12656.7
1.1025y = 18536.7
y = 18536.7 / 1.1025
y = 16813.33
Hence,
Sales price of washing machine = 16813.33
Total amount paid = (5880 + 5880 + 5880) = 17640
Interest paid = $(17640 - 16813.33) = $826.67
= $827
The total interest paid by him in this scheme, if the rate of interest is 5% compounded yearly is INR 826.67
Given:
Down payment = INR 5880
Payment at end of first year = INR 5880 (same as down payment)
Payment at end of second year = INR 5880 (same as down payment)
Interest rate = 5%
= 5/100
= 0.05 compounded yearly
Amount of purchase = x
Amount remaining after down payment
= x - 5880
Interest at end of first year :
(x - 5880) * 0.05(5,880)
= 0.05x - 294
Amount to pay plus interest = Amount remaining after down payment - amount paid at end of first year + interest
= x - 5880 - 5880 + 0.05x - 294
= x - 12,054 + 0.05x
= 1.05x - 12,054
2nd year interest :
(1.05x - 12054) * 0.05
= 0.0525x - 602.7
Amount left + interest = 2nd year payment
(1.05x - 12054) + (0.0525x - 602.7) = 5880
1.1025x - 12656.7 = 5880
1.1025x = 5880 + 12656.7
1.1025x = 18536.7
divide both sides by 1.1025
x = 18536.7 / 1.1025
x = 16,813.33
Therefore, The cost of washing machine b is INR 16,813.33
Total amount paid = (5880 + 5880 + 5880) = INR 17,640
Amount of Interest paid = (17640 - 16813.33)
= INR 826.67

I would not be surprised because 3% is not that far away from 9%. I would be surprised because Iowa City is a very clean community which means lots of people recycle their garbage.

It is found that on average, 9% of the population recycles its garbage. Under this assumption, if a random sample of 120 households in Iowa City is taken, would you be surprised to find that fewer than 3% of households in the sample recycle their garbage? Use the fact that p-hat has an approximately normal distribution.
Group of answer choices
A I would not be surprised because there are lots of lazy students in Iowa City.
B I would not be surprised because 3% is not that far away from 9%.
C I would be surprised because Iowa City is a very clean community which means lots of people recycle their garbage.
D I would be surprised because if the 9% average is true, the chance of a sample proportion being less than 3% is very small (only 1%). Who cares? It's only garbage!
Answer:
The correct option is D
Step-by-step explanation:
From the question we are told that
The sample size is n = 120
The mean of the proportion is p = 0.09
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{\frac{p(1-p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.09(1-0.09)}{120 } }[/tex]
=> [tex]\sigma = 0.02612[/tex]
Generally the chance that fewer than 3% of households in the sample recycle their garbage is mathematically represented as
[tex]P(X < 0.03) = P( \frac{X - p}{\sigma} < \frac{0.03 -0.09}{0.02612} )[/tex]
[tex]P(X < 0.03) = P( Z < -2.297 )[/tex]
From the z-table
[tex]P( Z < -2.297 ) = 0.01[/tex]
=> [tex]P(X < 0.03) = 0.01/tex]
=> [tex]P(X < 0.03) = 1\% /tex]

Multiples of 12 are -
1 x 12 = 12
2 x 12 = 24
24 is their least common multiple.

Answer:
Step-by-step explanation:
Both angles added together = 180 degrees. They both have a straight line as their base.
So let <ABC = x
Then <CBD = 3x Add the two angles
x + 3x = 180 Combine
4x = 180 Divide by 4
4x/4 = 180/4
x = 45
So 3x = 3*45 = 135

[tex](x+5)^2=4[/tex]
Step-by-step explanation:
We have:
[tex]x^2+10x+21=0[/tex]
First, subtract 21 from both sides:
[tex]x^2+10x=-21[/tex]
Now, we can complete the square. We will divide the coefficient of the b term and square it. So:
[tex](\frac{b}{2})^2\Rightarrow(\frac{10}{2})^2=(5)^2=25[/tex]
So, we will add 25 to both sides:
[tex](x^2+10+25)=-21+25[/tex]
The left is the perfect square trinomial pattern. Add on the right:
[tex]((x)^2+2(5)(x)+(5)^2)=4[/tex]
Final step:
[tex](x+5)^2=4[/tex]

Answer:
y = 3x - 6
Step-by-step explanation:
What you do is you plug both points in for the equation 2 times and solve as a system of equations.
Equation of a line: y = mx + b
(x,y) = (3,3)
(x,y) = (6,12)
3 = 3m + b
12 = 6m + b
Subtract equations to get rid of b to solve for m.
12 - 3 = 6m - 3m + b - b
9 = 3m
m = 3
Plug m back into both equations get b.
3 = 3(3) + b
b = -6
12 = 6(3) + b
b = -6
y = 3x - 6
Answer:
[tex]\displaystyle y = 3x - 6[/tex]
Step-by-step explanation:
First, find the rate of change of the line:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-3 + 12}{-3 + 6} = m \hookrightarrow \frac{9}{3} = m \\ \\ \boxed{3 = m}[/tex]
_______________________________________________
Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:
[tex]\displaystyle 12 = 3[6] + b \hookrightarrow 12 = 18 + b; -6 = b \\ \\ \boxed{\boxed{y = 3x - 6}} \\ \\ OR \\ \\ 3 = 3[3] + b \hookrightarrow 3 = 9 + b; -6 = b \\ \\ \boxed{\boxed{y = 3x - 6}}[/tex]

The perimeter of a rectangle is 14 inches. The equation that represents the perimeter of the rectangle is 2l+2w=14, where l represents the length of the rectangle and w represents the width of the rectangle. Which value is possible for the length of the rectangle?
6 inches
7 inches
8 inches
9 inches
Answer:
6 inches
Step-by-step explanation:
6 inches is the only feasible answer because if the length is 6 inches, you have 6 + 6 which equals 12. This leaves 2 more units for the perimeter so the width would be 1 unit. The other choices could not exist, because 7 x 2 is 14 (no units left for width, and the width of a rectangle cannot be 0), 8 x 2 is 16, and 9 x 2 is 18.
