Answer: 27

Step-by-step explanation:

Given

During 3 days the cat was catching mice

Suppose the first-day joy caught x mice

So, on the second day, it is x+3

on the third day, joy catches twice as many mice as on the first day i.e. 2x

or we can also write, no of mice caught on the second day plus 3 is equal to no of mouse caught on the third day

[tex]\Rightarrow x+3+3=2x\\\Rightarrow x=6[/tex]

In three day time, it is

[tex]\Rightarrow x+x+3+2x\\\Rightarrow 4x+3\\\Rightarrow 4\times 6+3=27[/tex]

Answer:

the number of copies have been sold to date is 3,036 copies

Step-by-step explanation:

Given that

There is 31,300 book copies sold in the first month

And, this represent 9.7% of the number of copies sold to date

we need to find out the no of copies have been sold to date

So,

= 31,300 copies × 9.7%

= 3,036 copies

Hence, the number of copies have been sold to date is 3,036 copies

Therefore the same would be considered and relevant too

Answer:

56m²

Step-by-step explanation:

separate shape into 2 shapes (i did 1 rectangle at top and 1 square at bottom.

find area separately so for rectangle, it would be 4x10 = 40m²

square = 4x4 = 16m²

then add together areas

16 + 40 = 56m²

Answer:

The total area is 56m²

Step-by-step explanation:

First divide the figure into two different parts; now we have a square and a rectangle. The square has a height of 4 and width of 4 so multiply both numbers to get your area. The rectangle has a height of 4 and an unknown width, with the information we have we know the width of the rectangle has at least 3m² on one side and 3m² on the other. Where we divided the figures we   see the bottom width of the square is 4 which is the missing length to complete the rectangles width. Add 3 plus 3 plus 4 and you have your width. Since now we know that the width of the rectangle is 10 we can use the formula to get the area: 10 times 4 equals 40 the area of the rectangle is 40m².

Area of square: 16m²

Area of rectangle: 40m²

Add the areas of both shapes and that makes the area of the shape previously shown.

The total area is 56m²

Answer:

slope=-9/2

y int- 6

Step-by-step explanation:

okay lets take two points

-2,15 and -6,33

the slope is 33-15/ -6-(-2)= 18/-4=-9/2

equation is y=mx+b where m is slope and b is y intercept

so plugging values in we get

15=-2(-9/2)+b

15=9+b

b=6

Answer:

The missing side length is 24.98 units

Step-by-step explanation:

Given

The attached right-triangle

Required

The length of the missing length

Let the missing length be x.

Apply Pythagoras theorem

[tex]Hyp^2 = Opp^2 + Adj^2[/tex]

This gives

[tex]43^2 = 35^2 + x^2[/tex]

[tex]1849 = 1225 + x^2[/tex]

Collect like terms

[tex]x^2 = 1849 - 1225[/tex]

[tex]x^2 = 624[/tex]

Take square roots of both sides

[tex]x = \sqrt{624[/tex]

[tex]x = 24.98[/tex] --- approximated

Delta math

Answer:

x = 29

Step-by-step explanation:

Given:

m<PQS = 107°

m<RQS = 49°

m<PQR = (2x)°

Required:

Value of x

Solution:

m<RQS + m<PQR = m<PQS (angle addition postulate)

Plug in the values

49 + 2x = 107

Subtract 49 from each side

2x = 107 - 49

2x = 58

Divide both sides by 2

x = 58/2

x = 29

Answer:

Lower confidence boundary = 134.525

μ ≥ 134.525

Step-by-step explanation:

From the data:

Sample size, n = 153

Sample mean, xbar = 135.39

Standard deviation, s = 4.59

Zcritical at 99% = 2.33 (one sided)

Confidence interval :

Xbar ± standard Error

Standard Error = Zcritical * s/√n

Standard Error = 2.33 * 4.59/√153 = 0.865

Lower boundary:

Xbar - standard error

135.39 - 0.865 = 134.525

μ ≥ 134.525

We Can be 99% confidence that the true average ultimate tensile strength is atleast 134.525

Find the actual Dimensions of the triangle.

Multiply the size of the triangle on paper by 1.5 feet per inch:

Width = 5 x 1.5 = 7.5 feet.

Height= 7 x 1.5 =10.5 feet

Area of a triangle is 1/2 x base x height:

Area = 1/2 x 7.5 x 10.5 = 39.375 square feet.

Answer: 39.375 square feet.

The area of the actual banner is 39.375 feet²

Scaling is used to increase or decrease the size of a figure so as to create an image.

Given that 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, hence:

Base = 5 in * 1.5 feet per in = 7.5 feet

Height = 7 in * 1.5 feet per in = 10.5 feet

Area of the actual banner = (1/2) * 7.5 * 10.5 = 39.375 feet²

The area of the actual banner is 39.375 feet²
