Answer:

20.25

Step-by-step explanation:

Use the “ %/100 = is/of ” method

45          ?

100          45

cross mutilps 45(45) = 2,025

then divide 2,025 by 100 = 20.25

Answer:

2/3

Step-by-step explanation:

When a line is parallel to another, it means that there are never going to be any solutions(they won't ever intersect each other.) To do so, the slope of the lines have to be the same. It doesn't matter what the y-intercept is.

So the slope of the second line is going to be the same as the first line: 2/3

Answer:

14000

Explaination:

spwithvat = sp without vat + 13% of sp without vat

let, sp without vat be x.

sp with vat= x + 13% of x.

or, 13447 = x + 13/100 × x

or, 1344700 = 113x

or, x= 1344700/113

x = 11900

Let, mp be y.

sp with vat = mp - 15% of mp

or, 11900 = y - 15/100 × y

or, 1190000 = 85y

or, y= 1190000/85

y= 14000

Answer:

The length is 12

Step-by-step explanation:

rectangle = 2w + 2l

Substitute 15 with w

2l + 2(15) = 54

Multiple

2l + 30 = 54

Subtract 30 from both side

2l = 24

divide by 2

l = 12

Answer:

[tex]3\frac{1}{4}[/tex] inches

Step-by-step explanation:

Height of the tallest conifer = [tex]9\frac{1}{2}[/tex] inches

Height of the shortest conifer = 6 + measure of one segment on the number line

Measure of one segment on the number line = [tex]\frac{6\frac{1}{2}-6}{2}[/tex]

                                                                           = [tex]\frac{\frac{1}{2}}{2}[/tex]

                                                                           = [tex]\frac{1}{4}[/tex]

Therefore, height of the shortest conifer = 6 + [tex]\frac{1}{4}[/tex]

                                                                    = [tex]6\frac{1}{4}[/tex]

Difference in tallest and shortest conifer = [tex]9\frac{1}{2}- 6\frac{1}{4}[/tex]

                                                                    = (9 - 6) + [tex](\frac{1}{2}- \frac{1}{4})[/tex]

                                                                    = 3 + [tex]\frac{1}{4}[/tex]

                                                                    = [tex]3\frac{1}{4}[/tex] inches

Answer:

Step-by-step explanation:

M = sum of the terms / number of the terms

1. Mean = 145/5 = 29

Option A is the correct answer

2. Mean = 35 /5 = 7

Option B is the correct answer

Answer:

1. 29 (A) 2. 7 (B)

Step-by-step explanation:

1. 2+57+38+42+6 = 145

145/5 = 29

2. 4+9+7+10+5 = 35

35/5 = 7

Step-by-step explanation:

1. -6u= -29-7

-6u÷-6= -36÷-6

u= 6

2. 6m= -23-1

6m÷6= -24÷6

m=-4

3. 4d=37-5

4d÷4=32÷4

d=8

Answer:

4. -6u+7=-29

-6u=-29-7

-6u=-36

-6u=-36

(divide both sides by-6 )

-6u/-6=-36/-6

u=6.

5. 6m+1=-23

6m=-23-1

6m=-24

divide-24 by 6

m=-4

6. 5+4d=37

4d=37-5

4d=32

divide by 4

d=8

Answer:

401.92

Step-by-step explanation:

The formula used the calculate the volume of a cylinder is

πr^2h

π= 3.14

H= 8

r= 4

Volume= 3.14 × 4^2 × 8

= 3.14 × 16×8

= 401.92

Hence the volume is 401.92

Answer:

35

Step-by-step explanation:

The measure of an inscribed angle whose endpoints are points S and T will be 35°.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The central angle is double the angle at the periphery that was subtended by the same chords.

The central angle of arc ST is 70°.

The measure of an inscribed angle whose endpoints are points S and T is given by the half of the central angle of arc ST. Then we have

Inscribed angle = 70° / 2

Inscribed angle = 35°

The measure of an inscribed angle whose endpoints are points S and T will be 35°.

Step-by-step explanation:

Trust me bro

Water is the Adjacent of this right triangle. 350 yards is the length of the Hypotenuse. We have given angle B, 40 degrees.

_________________________________________________________

According to SOH CAH TOA, we use CAH (cosineΘ = adjacent/hypotenuse).

cosine40 = x/350

[multiply both sides by 350]

350 · cosine40 = x

[put calculator in degree mode]

x ≈ 268 yards

So, the distance across the water from sailboat to the island is 268 yards.

_________________________________________________________

Let's use pythagorean theorem since we already know the adjacent and hypotenuse to find the opposite (opposite is also known as height).

a^2 + b^2 = c^2

a^2 + (268)^2 = (350)^2

a^2 + 71824 = 122500

a^2 = 122500 - 71824

a^2 = 50676

[square both sides]

[tex]\sqrt{a^2}[/tex] = [tex]\sqrt{50676}[/tex]

a = [tex]\sqrt{50676}[/tex]

a ≈ 225

So, the height, opposite, of the lighthouse is 225 yards.

Answer: [tex]432\pi \text{ cubic centimeters}[/tex] or [tex]1356.48\text{cubic centimeters}[/tex]

Step-by-step explanation:

Volume of right circular cylinder = [tex]\pi r^2 h[/tex]

Given: Radius = 6 centimeters

Height = 12 centimeters

Then, the volume of this cylinder = [tex]\pi (6)^2 \times (12)= 432\pi \text{ cubic centimeters}[/tex]

Hence, the volume of this cylinder = [tex]432\pi \text{ cubic centimeters}[/tex]

At [tex]\pi=3.14[/tex]

The volume of this cylinder[tex]=432\times3.14=1356.48\text{cubic centimeters}[/tex]
