Step-by-step explanation:

since you can just add 4 to 36 to get 40.

Answer:

40

Step-by-step explanation:

Let n represent the number then...

n-4=36

Add 4 to both sides

n-4+4=36+4

n=40

The number is 40

Answer:

[tex]\boxed{\sf{-3}}[/tex]

Step-by-step explanation:

You can solve this problem by using the slope formula to find the slope of the line.

Slope formula:

[tex]\sf{\dfrac{Y_2-Y_1}{X_2-X_1}=\dfrac{RISE}{RUN}}[/tex]

y2=(-2)

y1=10

x2=(-5)

x1=(-9)

Rewrite the problem down and then solve it.

[tex]\sf{\dfrac{(-2)-10}{(-5)-(-9)} }=\dfrac{-2-10}{-5+9}=\dfrac{-12}{4}[/tex]

Divide by 4 as well.

[tex]\sf{\dfrac{-12\div4}{4\div4}=\dfrac{-3}{1}=\boxed{\sf{-3}}}[/tex]

Therefore, the slope is -3.

Answer:

112

Step-by-step explanation:

There are 400 employees. If 72 of them work part-time, then 72% of 400 = 400*72%. This equals 288. Then you subtract that from 400 because the rest of them should be full-time workers. 400-288=112.

Answer:

112

Step-by-step explanation:

400 x 0.72 = 288, so that's the number of part-time employees.

400 - 288 = 112

Answer:

60%

Step-by-step explanation:

Answer: See below

Step-by-step explanation:

Let s represent Sipho's age and let l represent Litha's age

The sum of their ages is 29 years

s + l = 29...(1)

In 6 years time, Sipho (s+6), will be the same age Litha was 3 years ago (l-3)

(s+6) = (l-3)...(2)

Age:

s + l = 29

s = 29 - d (express c in d)

(29-s+6) = s - 3 (substitute c)

s+(29-s+6) = s+(d-3)

29+6 = 2s -3

29+6+3 = 2s

38 = 2s

19 = s

Back to (1):

l = 29 - 19

l = 10

Therefore, Sipho is currently 19 years old and Litha is 10 years old

The current age for the two brothers, Sipho and Litha is 10 years old and 19 years old respectively.

A linear equation is the equation in which the highest power of the unknown variable is one.

To solve this problem, let's make the linear equations by the given statement.

Let x be the age of Sipho and y is the age of Litha. The sum of their ages is 29. Therefore,

[tex]x+y=29\\y=29-x[/tex]

Thus, the age of Litha is (29-x)

In 6 years' time, Sipho will be the same age as Litha was 3 years ago. Therefore,

[tex]x+6=(29-x)-3\\x+6=29-x-3\\x+x=29-3-6\\2x=20\\x=\dfrac{20}{2}\\x=10[/tex]

Thus, the age of Sipho is 10 years. The age of Litha is,

[tex]y=29-10\\y=19[/tex]

Hence, the current age for the two brothers, Sipho and Litha is 10 years old and 19 years old respectively.

The function to model the path of the fireworks in the new location is -4.9(t - 4)^2 + 50

Given the height reached by the flight expressed as:

h(t) = -4.9(t - 4)^2 + 80

If the barge is relocated 30 meters to the east, the new function will be derived by subtracting 30 from the initial function

New function = -4.9(t - 4)^2 + 80 - 30

New function = -4.9(t - 4)^2 + 50

Hence the function to model the path of the fireworks in the new location is -4.9(t - 4)^2 + 50

Answer:

volume: 49280 cm³  and   curved S.A = 5826.64 cm²

Explanation:

using similarities:

[tex]\sf \frac{45 + h2}{28} = \frac{h2}{7}[/tex]

[tex]\sf 315 + 7h2 = 28h2[/tex]

[tex]\sf 315 = 28h2-7h2[/tex]

[tex]\sf 315 = 21h2[/tex]

[tex]\sf 15 = h2[/tex]

total height of the cone: 45 + 15 = 60 cm

solve for volume:

[tex]\sf volume \ of \ cone \ = \frac{1}{3} \pi r^2 h[/tex]

[tex]\sf volume \ of \ cone \ = \frac{1}{3} \pi (28)^2 (60)[/tex]

[tex]\sf volume \ of \ cone \ = 15680\ *\frac{22}{7}[/tex]

[tex]\sf volume \ of \ cone \ = 49280 \ cm^3[/tex]

First find the slant height using Pythagoras theorem -

[tex]\sf l^2 = r^2 + h^2[/tex]

[tex]\sf l =\sqrt{ r^2 + h^2}[/tex]

[tex]\sf l =\sqrt{ (28)^2 + (60)^2}[/tex]

[tex]\sf l =66.212 \ cm[/tex]

solve for curved surface area:

[tex]\sf curved \ surface \ area = \pi rl[/tex]

Answer: (k - 1) (9k^2 + 1)

Answer:

1072.3 cm³ (1 dp)

Step-by-step explanation:

A hemisphere is half a sphere.

Therefore, calculate the volume of a sphere with radius 8 cm, then half it.

Volume of a sphere = 4/3 π 8³

                                  = 4/3 × π × 512

                                  = 2048/3 π cm³

Volume of hemisphere = (2048/3 π) ÷ 2

                                       = 1024/3 π

                                       = 1072.3 cm³ (1 dp)

The sum of all the angles of any quadrilateral is 360 degrees

             115 + 97 + 58 + missing angle = 360

                   missing angle = 90 degrees

Hope that helps!

Answer:

90

Step-by-step explanation:

Since sum of all the angles of any quadrilateral is 360 degrees

115 + 97 + 58 + x = 360

Solve for x:

Add the numbers

270 + x = 360

Rearrange terms

x + 270 = 360

Subtract 270 from both sides of the equation

x + 270 - 270 = 360 - 270

Simplify

x = 90

Missing angle = 90

The approximate diameter of the circular plate with circumference of 68.5 centimetre is 21.82 centimetres.

The circumference of a circle is the perimeter of a circle. Therefore, the formula of a circle can be represented as follows:

circumference = 2πr

where

Therefore,

circumference = 68.5 cm

68.5 = 2 × 3.14 × r

r = 68.5 / 6.28

r = 10.9076433121

radius = 10.907

Diameter = 2(radius)

Diameter  = 2 × 10.9076433121

check the image given below.

Let's say we had this data set

This is a collection of whole numbers and decimal values. We need to standardize everything so every value is the same length exactly. Something like "12" involves 2 digits while "12.7" involves 3 digits. We can rewrite 12 into 12.0 to standardize everything to 3 digits. Same goes for 13 into 13.0 and 14 into 14.0

This is the new updated list

Everything now has a decimal point and involves exactly 3 digits.

From here, we'll form the stems: 12, 13, 14

The leaf values are the last digit. Each separate leaf digit refers to one exact number from the original data set.

Refer to the stem-and-leaf plot below.

As you can see, something like 13.0 is smaller than 13.1; therefore, the whole numbers are smaller than the decimal values for a given stem only.

Answer:

Train A : 143 tons ; Train B : 18 tons

Step-by-step explanation:

Call train A as A, train B as B

A + B = 161t
A - B = 125t

A = (161+125) : 2 = 143t
B = 143t - 125t = 18t

The sides and angles of a triangle can be determined using trigonometry ratios

The values of x, y and z are [tex]x = 14\sqrt 2[/tex], [tex]y =14[/tex] and [tex]z = 14\sqrt 3[/tex]

The upper triangle is a right triangle with an angle measure of 45 degrees.

So, the value of x is:

[tex]x = 14\sqrt 2[/tex]

Next, we calculate the hypotenuse (h) of the lower triangle using:

[tex]h^2 = (14\sqrt 2)^2 + (14\sqrt 2)^2[/tex]

So, we have:

[tex]h^2 = 784[/tex]

Take the square roots of both sides

[tex]h = 28[/tex]

The value of y is then calculated using the following sine ratio

[tex]\sin(30) = \frac y{28}[/tex]

Make y the subject

[tex]y =28 * \sin(30)[/tex]

Evaluate

[tex]y =14[/tex]

The value of z is then calculated using the following cosine ratio

[tex]\cos(30) = \frac z{28}[/tex]

Make z the subject

[tex]z =28 * \cos(30)[/tex]

Evaluate

[tex]z =28 * \frac{\sqrt 3}{2}[/tex]

[tex]z = 14\sqrt 3[/tex]

Hence, the values of x, y and z are [tex]x = 14\sqrt 2[/tex], [tex]y =14[/tex] and [tex]z = 14\sqrt 3[/tex]

Step-by-step explanation:

Positive sign denotes that it has gained

The slope of the line that passes through the points (0,-10) and (-4,-11) will be 1/4.

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other. The more the slope is, the more the line is vertical. When slope is zero, the line is horizontal.

Its slope would be:

[tex]m = \dfrac{y-q}{x-p}[/tex]

Given that the line passes through the points (0,-10) and (-4,-11).

From the formula to find the slope of a line which passes through points

m= y2-y1 / x2-x1

Substitue the points (0,-10) and (-4,-11).

The slope = m = -11-(-10) /. -4-0

m = -1/-4

m = 1/4

Therefore, the slope of the line that passes through the points (0,-10) and (-4,-11) will be 1/4.
