Answer:

About 11.48

Step-by-step explanation:

6.4+2.75=9.15

2 1/3=2.33

9.15+2.33=11.48

The speed the fan will turn is 625 rpm

Since they fan and the pulley ahve the same linear speed v = rω where

Then

r₁ω₁ = r₂ω₂ where

Making ω₁ subject of the formula, we have

ω₁ = r₂ω₂/r₁

Substituting the values of the variables into the equation, we have

ω₁ = r₂ω₂/r₁

ω₁ = 2 in × 1250 rpm/4 in

ω₁ = 1250 rpm/2

ω₁ = 625 rpm

So, the speed the fan will turn is 625 rpm

We calculate the volume of the cuboid :

60 x 100 x 40 = 240000 cm^3

If every bag has 8000 cm^3 of grit, he will need 240000 : 8000 = 30 bags

Every bag cost £2.50, so he will need £2.50 x 30 = £75

Since he only has £70, he doesn't have enough money to buy the grit.

Step-by-step explanation:

The given dimensions are related by the perimeter formula for a rectangle.

Let w represent the width in meters. Then (w+5) represents the length. These values can be put into the perimeter formula, which can be solved to find w.

  P = 2(L +W)

  82 = 2((w+5) +w) . . . . fill in for L and W

  41 = 2w +5 . . . . . . . . divide by 2

  36 = 2w . . . . . . . . . subtract 5

  18 = w . . . . . . . . . divide by 2. This is the width.

  w+5 = 18+5 = 23 . . . . find the length

The length of the rectangle is 23 m; the width is 18 m.

Using it's concept, it is fond that the estimate for the ratio of red to blue beads is of 91:79.

The ratio between two amounts a and b is given by a divided by b, that is:

[tex]\frac{a}{b} = a:b[/tex]

In this problem, considering Charlotte's and Harry's beads, there are 81 + 10 = 91 red beads and 9 + 70 = 79 blue beads, hence the ratio is given by:

91:79.

Answer:

The answer is 2.Divide each side by 2

Simplify : y = 2x + 3

Replace x = 1 -> y = 5

We will draw a line that goes through the point 1 on the x axis, and point 5 on the y axis (cant draw right now, sorry xd)

(Now, you can find the gradient by simply forming a right triangle with the hypotenuse being the line itself, but i will use the slope to save time)

Based on the percentages given on those who visited the Great Wall, the relative frequencies will show the following?

The number of people who went to Great Wall was:

= 200 x 85%

= 170 people

= Number of people who went to Great Wall x 30%

= 170 x 30%

= 51 people

= (1 - 85%) x Number of people surveyed x 80%

= 0.15 x 200 x 80%

= 24 people

Answer:

m<U=70

Step-by-step explanation:

we know that the measure of the out side angle is equal to the measure of the 2 inside angles, so 120-50=70

Answer:

∠ U = 70°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ RVU is an exterior angle of the triangle , then

∠ U + 50° = 120° ( subtract 50° from both sides )

∠ U = 70°
