All the children of a class were asked to choose between the cartoon shows 'Shin Chan' and 'Tom and Jerry'.The ratio of children who selected the cartoon 'Shin Chan' to those who selected the cartoon 'Tom and Jerry', was 3:1.
If 45 kids selected 'Shin Chan', how many students are there in the class totally?

Answers

Answer 1

Answer:

There were 60 kids in class.

Step-by-step explanation:

Since the kids had two choices and the ratio between them was for every 3 children that selected "Shin Chan" only 1 selected "Tom and Jerry", then in order to calculate the number of children in the class if 45 kids selected "Shin Chan", we first need to calculate the number of children that selected the other option. To do that we divide the number by 3. We have:

children(Tom and Jerry) = children(Shin Chan)/3

children(Tom and Jerry) = 45/3 = 15

Therefore the number of children in the class is:

children(class) = children(Tom and Jerry) + children(Shin Chan)

children(class) = 15 + 45 = 60

There were 60 kids in class.

A metal shop is cutting a rectangular piece of sheet metal with a width of 60 inches and a length of 144 inches. The shaded parts of the diagram represent two rectangular sections, A and B, that will be cut and removed.

Part A :What are the dimensions of section B?​
Part B:What will be the area, in square inches, of the piece of sheet metal after both sections are cut and removed?



Answers

Answer:

Dimensions of section B = 36 inches, 48 inches

Area of the piece of sheet metal after both sections are cut and removed  = 6336 square inches

Step-by-step explanation:

Given: Width and length of a rectangular piece of sheet metal are 60 inches and 44 inches.

To find: dimensions of section B, the area of the piece of sheet metal after both sections are cut and removed

Solution:

Length of rectangle B = TR = SR - ST = PQ - ST (As SR = PQ being opposite sides of rectangle)

Length of rectangle B = PQ - ST = 60  - 24 = 36 inches

Breadth of rectangle B = UR = QR - QV - VT - TU

Here, QR = PS = 144 inches (opposite sides of rectangle PQRS are equal )

QV = 36 inches

VT = WX = 24 inches ( opposite sides of rectangle WVTX are equal)

TU = 36 inches

So,

Breadth of rectangle B = 144 - 36 - 24 - 36 = 48 inches

Area of rectangle B = length × breadth = 36 × 48 = 1728 square inches

Area of rectangle WVTX = length × breadth = 24 × 24 = 576 square inches

Area of rectangle PQRS = PQ × PS = 60 × 144 = 8640 square inches

Area of the piece of sheet metal after both sections are cut and removed =8640 - ( 1728 + 576 ) = 8640 - 2304 = 6336 square inches

Elise is a project manager
In 2016 she earned a monthly salary of £2,100
in 2017 she had a 3% raise
Given that in 2017 Elise worked 42 hours per week for 45 weeks, work out her average pay per hour for the year
please help :(

Answers

Answer:

£11.85

Step-by-step explanation:

In the question, we are told that:

In 2016 she earned a monthly salary of £2,100

In 2017 she had a 3% raise

This means 3% of £2,100

3/100×£2,100 = £63

This means her salary for 2017 =

£63 + £2,100 =£2,163

Step 2

We are told in the question that she worked 42 hours per week for 45 weeks in 2017

Since her monthly pay for 2017 = £2,163

She worked 42 hours per week

There are 7 days in one week

The number of hours she worked per day = 42 hours ÷ 7 = 6 hours per day

4.345 weeks= 1 month

The number of hours she worked per month = 42 hours × 4.345 weeks

= 182.49 hours.

We can say that for 182.49 hours she was paid = £2,163

Her average pay per hour is calculated as:

If 182.49 hours = £2,163

1 hour = represented by Y

Cross multiply

182.49Y = £2,163

Y = £2,163 ÷ 182.49

Y = £11.852704258

Approximately = £11.85

Therefore, Elise Average pay per hour for the year = £11.85

Answers

Answer:

244 degrees

Step-by-step explanation:

Since one angle APE is 90 degrees, that means line segments AD and BE are perpendicular bisectors.

Since both segments go through the center, that means all the angles are central angles.

Since angle APE is 90 degrees, that also means that angle EPD is 90 degrees.

33k -9 = 90

33k = 99

k = 3

Since we know k we can substitute it to find angle CPD.

20 k + 4 = 20*3 + 4= 60+4= 64 degrees.

Central angles equal angles of arcs, so we can and angles APE, EPD, and DPC to find the measure of major arc CAD.

64+ 90 +90 = 244 degrees

Maureen earned some money doing odd jobs last summer and put it in a savings account that earns 9% interest compounded quarterly. After 10 years, there is $300.00 in the account. How much did Maureen earn doing odd jobs?

Answers

Answer:

Maureen earned $123.19 doing odd jobs

Step-by-step explanation:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.

In this question:

Compounded quarterly means that [tex]n = 4[/tex]

10 years, so [tex]t = 10[/tex]

9% interest, so [tex]r = 0.09[/tex]

There is $300.00 in the account, which means that [tex]A = 300[/tex]

How much did Maureen earn doing odd jobs?

This is P.

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]300 = P(1 + \frac{0.09}{4})^{4*10}[/tex]

[tex](1.0225)^{40}P = 300[/tex]

[tex]P = \frac{300}{(1.0225)^{40}}[/tex]

[tex]P = 123.19[/tex]

i need to find the value of x

Answers

Answer:

x = 24

Step-by-step explanation:

Since all the angles share a common vertex 'U' lying on a straight line QT.

Therefore, sum of all angles formed at U will be equal to 180°.

m∠RUQ + m∠RUS + m∠SUT = 180°

(2x - 4) + (3x + 5) + (2x + 11) = 180°

(2x + 3x + 2x) + (5 - 4 + 11) = 180

7x + 12 = 180

7x = 180 - 12

x = [tex]\frac{168}{7}[/tex]

x = 24

Therefore, value of x = 24

Andrea uses 9.8 pints of blue paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?

Answers

Answer:

5.88 pints

Step-by-step explanation:

Well the amount of white paint is 3 / 5 of 9.8

0.6 * 9.8 = 5.88

Answer: 14.7 pints of white paint

IF two different colors were used.

IF she mixed paint to get a light blue, 3/5 of the total would be about 5.9 pints.

Step-by-step explanation:

If 9.8 is 2/5 of the total amount used, set up the equation as 9.8= 2x/5

You get the total amount of paint used is 24.5 pints. Subtract the 9.8 of blue to find the amount of white. That's 14.7 pints.

In practical, real life, a quart of paint covers about 100 square feet. That's an average 8 ft high by 12 ft wide wall.

So that is why I edited this answer. 24 pints is 3 gallons-- that is enough for 3 bedrooms.

And I wish that Math teachers used more common measurements of paint!

What is the probability of picking an even number and then picking an even number?

Simplify your answer and write it as a fraction or whole number.

Answers

1/6 and you got the comment why

Answer:

1/6

Step-by-step explanation:

Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!

Step-by-step explanation:

There are two ways to do this. You can either find out what 11% of $23,000 is by multiplying .11 by $23,000, then subtract this from $23,000 to find the yearly increase, where you can then divide by 12, or you can divide .11 by 12 and then multiply this by $23,000.

Step-by-step explanation:

Let our quadratic polynomial function [tex]f(x)=x^2-7x+6[/tex]

Let our linear binomial in the form (x − a)=x-1

The measure of the angle d for m angle b = 65 in the figure of circle and quadrilateral is 50 degrees. Option A is correct.

What is a measure of angle?

The measure of angle between the two points of a ray or line is the measure of rotation between these two points. The angles are measured in degrees or radians.  

The figure given in the problem contained a circle and a quadrilateral.

In this figure, the measure of the angle b is,

[tex]m\angle d =65^o[/tex]

Here, the two tangent lines AD and DC cuts the circle at point A and C respectively.

Let the center of the circle is O. Thus the angle b is equal to the angle AOC by the tangent line theorem as,

[tex]\angle O =2m\angle b=130 ^o[/tex]

The sum of angle AOC and the angle D is equal to 180 degrees. Therefore,

[tex]\angle AOC+m\angle d=180\\130++m\angle d=180\\m\angle d=180-130\\m\angle d=50^o[/tex]

Hence, the measure of the angle d for m angle b = 65 in the figure of circle and quadrilateral is 50 degrees. Option A is correct.

Answer:

x = 4 ±√26

Step-by-step explanation:

Please write this as x^2 - 8x = 10, or x^2 - 8x - 10 = 0.  " ^ " indicates exponentiation.

Let's complete the square:

x^2 - 8 x can be rewritten as

x^2 - 8x + 16 - 16, and so

x^2 - 8x = 10 becomes x^2 - 8x + 16 - 16 - 10 = 0, or

                                         (x - 4)^2 = 26

Taking the square root of both sides, we get:

x - 4 = ±√26, or
