Answer: 7 3/5 + 2 1/2 = 10 1/10
Step-by-step explanation:
Write the fractions to have like denominators to make it easier to add.
7 3/5 will become 7 6/10
2 1/2 will become 2 5/10
Rewrite them as improper fractions:
7 6/10 will become 76/10
2 5/10 will become 25/10
Now add.
76/10+25/10=101/10
Rewrite the sum as a mixed number
101/10 will become 10 1/10
Salads A restaurant wants to study how well its salads sell. The circle graph shows the sales over the past few days. If 15 of the salads sold were Caesar Sold salads, how many total salads did the restaurant sell? Caesar 60%Garden 28% Taco 12%
Circle graphs are used to represent data in percentages and proportions
There are 25 salads in the restaurant shelf
How to determine the total saladsFrom the question, we have:
The number of Caesar salad = 15The percentage of Caesar salad = 60%So, the total number of salad is:
n * 60% = 15
Divide both sides by 60%
n = 25
Hence, there are 25 salads in the restaurant shelf

Pankaj borrows rupees 57,000 to buy a used car and is charged the rate of interest 6% per annum. if the term of his borrowing is 4 years, how much interest does he pay?
Rs.13680 is the answer.
Step-by-step explanation:-
Given-
•Principal (P) = Rs.57,000
•Rate (r%) = 6%
[tex]→ \frac{6}{100} [/tex]
[tex]→ 0.06[/tex]
•Time (n) = 4 years

2 1/4 x4/5 ÷ 3/5 - 1/2
Answer:
2.5.2 1/2.Step-by-step explanation:
We need to solve in the most hard way.
Equation simplified:
((((2 1/4) * 4/5) / (3/5)) - (1/2)Solve left to right:
((((2 1/4) * 4/5) / (3/5)) - (1/2)= ((((2 1/4) * 4/5) / (3/5))= 3 - 1/2= 2 1/2.If we solve this separately, starting with 2 1/4 * 4/5 without dividing 3/5, we would be doing it wrong.
If we do it like this, we would get the correct answer.
2 1/2 is the answer.
A common denominator for 5/6 and 3/5 is
30
factors of 6: 6 12 18 24 30
factors of 5: 5 10 15 20 25 30
so its 30
or simply multiple the denominators 6×5=30

Answer:
i) Area = 25 m²
ii) slope of roof = 36.87°
Step-by-step explanation:
(i) Let the midpoint of AB = M
Find BC by using Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Legs = MB and MC, hypotenuse = BC
⇒ 1.5² + 2² = BC²
⇒ 6.25 = BC²
⇒ BC = √(6.25) = 2.5
Area of a rectangle = width x length = BC x BE
⇒ area of BCFE = 2.5 x 5 = 12.5
⇒ area of ACFD = area of BCFE = 12.5
Therefore area covered by tiles = 12.5 + 12.5 = 25 m²
ii)
The angle of the slope of the roof will be angle ∠B of the right triangle ΔCMB.
Using sin(A)/a = sin(B)/b = sin(C)/c
sin(90)/2.5 = sin(B)/1.5
0.4 = sin(B)/1.5
0.6 = sin(B)
∠B = 36.87°
solve for y and show all work.

10postmen can sort 500 letters in 30 minutes.How many postmen are needed to sort 600 letters in 20 minutes
Answer: 18
Step-by-step explanation:
We want to find out how many letters each postman can sort in an hour to make the process easier. Since we're already told that 10 postmen can sort 500 letters in 30 minutes, we can use that info to find that each postman can sort 100 letters per hour as 10 postmen would be able to sort 1000 letters in 1 hour.
Then, we can apply this info to find out how many postmen can sort 600 letters in 20 minutes. We can multiply the time and task each by 3 to find that this is the same rate as sorting 1800 letters in 1 hour, so the answer is 18 postmen.

The quartiles of any Normal distribution are about __________ standard deviations from the mean. Give your answer to 3 decimal places.
Answer:
(1) The first quartile of standard normal distribution is -0.67.
(2) The third quartile of standard normal distribution is 0.67.
(3) The percentage of the observations in the standard normal distribution that are suspected outliers is, 0.74%.
Explanation:
A standard normal distribution has mean 0 and variance 1.
(1)
The first quartile of any data is the value below which 25% of the data lie.
That is, P (Z < z) = 0.25.
The value of z is -0.67.
Thus, the first quartile of standard normal distribution is -0.67.
(2)
The third quartile of any data is the value below which 75% of the data lie.
That is, P (Z < z) = 0.75.
The value of z is 0.67.
Thus, the third quartile of standard normal distribution is 0.67.
(3)
In case of a standard normal distribution values lying outside the range
(Q₁ - 1.5 IQR, Q₃ + 1.5 IQR)
are considered as outlier.
Compute the range as follows:
Compute the probability of (Z < -2.68) and P (Z > 2.68) as follows:
The probability of a value being an outlier is,
P (Outlier) = P (Z < -2.68) + P (Z > 2.68)
= 0.0037 + 0.0037
= 0.0074
The percentage of the observations in the standard normal distribution that are suspected outliers is, 0.0074 × 100 = 0.74%.

What is the answer for 1 + 2(p + 10
A is the point (-2,0)
B is the point (0,4)
C is the point (5,-1)
Find an equation of the line that passes through C and is perpendicular to AB
Answer:
y = 1/2x - 3.5
Step-by-step explanation:
so lets start by finding the equation of the line AB
we know the y-intercept is 4 from the point 0,4 so we know it'll look something like this
y = mx + 4 and we can plug in the other point we know -> 0 = m(-2) + 4 -> 4 = m(-2) -> m = -2 so the full equation of the line is y = -2x + 4
ok now we can find the other line. we know that perpendicular lines have an opposire reciprocal slope so in this case -2 would turn into 1/2
y = 1/2x + b
now lets plug in point C
-1 = (1/2)(5) + b
-1 - (2.5) = b
-3.5 = b
so the equation is y = 1/2x - 3.5
Answer:
[tex]y=-\dfrac12 x + \dfrac32[/tex]
Step-by-step explanation:
Equation of line AB:
Let A = [tex](x_1,y_1)[/tex] = (-2, 0)
Let B = [tex](x_2, y_2)[/tex] = (0, 4)
Use equation of slope to find slope m:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4 -0}{0+2}=2[/tex]
Use point-slope form for linear equation:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]\implies y-0=2(x+2)[/tex]
[tex]\implies y =2x+4[/tex]
Equation of line passing through C
If the line that passes through C is perpendicular to AB, then their slopes will be opposite reciprocals of each other.
⇒ [tex]m=\dfrac{-1}{2}=-\dfrac12[/tex]
Use point-slope form for linear equation and [tex](x_1,y_1)[/tex] is point C:
[tex]y-y_1=m(x-x_1)[/tex]
[tex]\implies y+1=-\dfrac12 (x-5)[/tex]
[tex]\implies y=-\dfrac12 x + \dfrac32[/tex]
