Rewrite 8.62 as a mixed number in simplest form.

Answer:

60. 15

---- = ------ x=25

100. x

Step-by-step explanation:

2x + 90 + x = 180

Subtract 90 from both sides

you get 3x = 90

Devide

[tex] \frac{3x}{3} = \frac{90}{3} \\ x = 30[/tex]

x=17

Step-by-step explanation:

Answer:

x - 9 = 8

Step-by-step explanation:

Given

x - 5 = 12 ( add 5 to both sides )

x = 17

Thus

x - 9 = 17 - 9 = 8

Answer:

the answer is B

Step-by-step explanation:

A scale factor is defined as the ratio between the scale of a given original object and a new object.

The image will be congruent to the pre-image because n = 1.

Option B is the correct answer.

A scale factor is defined as the ratio between the scale of a given original object and a new object.

We have,

A rectangle is dilated by a scale factor of n = 1.

This means that there is no change in the rectangle.

When the pre-image is the same as the image formed the scale factor is one.

The preimage is the original shape.

The image is the final image after dilation.

So,

The image will be congruent to the pre-image because n = 1.

Thus,

The image will be congruent to the pre-image because n = 1.

Option B is the correct answer.

hope this helps :)

Answer:

y-3=4(x+2)

Step-by-step explanation:

Once you know how the point slope form equation is laid out this question is actually quite easy. Point slope form looks like this

y-y2=slope(x-x2)

I put the y in the front and the slope (4) comes after the equal sign. Then x is subtracted from x. But I put a plus sign because when you subtract a negative number, it is the same as adding a negative number. This is why the ending part of the equation is (x+2) instead of (x--2). Hopefully this makes sense...

Answer:

a) The inequality representing the number of cases he can take =

180 + 47c ≤ 2700

b) 53 cases

Step-by-step explanation:

A worker is taking cases of screws on a lift. Each case weighs 47 pounds and the worker weighs 182 pounds. the lift

has a weight limit of 2700 pounds

a) Write an inequality that describes the number of cases he can safely take on each trip.

Let us represent the number of cases as c

hence,

180 + 47 × c ≤ 2700

= 180 + 47c ≤ 2700

b) What is the maximum amount of cases he can take?

The maximum amount of cases he can take =

180 + 47c ≤ 2700

180 + 47c = 2700

Collect like terms

47c = 2700 - 180

47c = 2520

c = 2520/47

c = 53.617021277 cases

c = 53 cases

The maximum number of cases he can carry is 53 cases

Answer:

The length is approximately 103.92 ft

Step-by-step explanation:

The angle the given ladder makes with the ground = 60°

The height to which the ladder reaches. h = 90 ft.

Assumption;

The angle formed between the wall and ground = 90°

The shape formed by the length, l, of the ladder the height to which the ladder reaches on the wall, h, and the ground, b, is a right triangle, with the length, l, of the ladder facing the 90° angle and the height, h, facing the 60° angle.

By sine rule, we have;

l/sin(90°) = h/sin(60°)

Therefore, the length l = sin(90°) × h/sin(60°) = 1 × 90/(sin(60°)) = 90/((√3)/2) = 2 × 90/√3 ≈ 103.92

The length, l ≈ 103.92 ft.

Answer:

Length of the first board is 20 inches.

Step-by-step explanation:

Let the length of first board is x and that of second board is five inches more than two times the length of the first board.

Length of second board = 5+2x

Total length of two boards is 65 inches

ATQ,

x+5+2x=65

3x+5=65

Taking like terms together,

3x=65-5

3x=60

x = 20

So, the length of the first board is 20 inches.

Answer:

The conversing factor is [tex]\dfrac{1}{1000}\ km[/tex].

Step-by-step explanation:

The average speed of a person is 18 km/h.

We need to convert the speed to meters/hour.

We know that,

1 km = 1000 m

or

[tex]1\ m=\dfrac{1}{1000}\ km[/tex]

So,

[tex]18\ \dfrac{km}{h}=18\times \dfrac{1000\ m}{h}\\\\=18000\ m/h[/tex]

So, the conversing factor is [tex]\dfrac{1}{1000}\ km[/tex].

Answer:

22.4 m/s

Step-by-step explanation:

Given:

Δx = 25 m

v₀ = 0 m/s

a = 10 m/s²

Find: v

v² = v₀² + 2aΔx

v² = (0 m/s)² + 2 (10 m/s²) (25 m)

v = 22.4 m/s

Answer:

Step-by-step explanation:

Answer:

Inter milan had 24 wins, 10 draws and 4 losses.

Step-by-step explanation:

Let n₁ = number of wins, n₂ = number of draws and n₃ = number of number of losses. Let W = win points = 3, L = loss points = 0 and D = draw points = 1 Since we have our total number of points a 82, then

n₁W + n₂D + n₃L = 82

3n₁ + n₂ + 0n₃ = 82   (1)

Also, since there are 38 points in total, we have that

n₁ + n₂ + n₃ = 38    (2)

Also, we have 20 more win points than loss points. So,

n₁ = n₃ + 20

n₁ + 0n₂ - n₃ = 20 (3)

We have 3 equations. We now write them in matrix form below.

[tex]\left[\begin{array}{ccc}3&1&0\\1&1&1\\1&0&-1\end{array}\right] \left[\begin{array}{ccc}n_{1} \\n_{2}\\n_{3}\end{array}\right] = \left[\begin{array}{ccc}82 \\38\\20\end{array}\right][/tex]

In the form AX = B, where A =  

[tex]A =\left[\begin{array}{ccc}3&1&0\\1&1&1\\1&0&-1\end{array}\right] , X =\left[\begin{array}{ccc}n_{1} \\n_{2}\\n_{3}\end{array}\right] and B= \left[\begin{array}{ccc}82 \\38\\20\end{array}\right][/tex]

Using cramer's rule, n₁ =

[tex]det\left[\begin{array}{ccc}82&1&0\\38&1&1\\20&0&-1\end{array}\right] /det\left[\begin{array}{ccc}3&1&0\\1&1&1\\1&0&-1\end{array}\right][/tex]

= 82((-1 × 1) - 0 × 1) - 1((38 × -1)- (20 × 1)) + 0((38 × 0) - 20 × 1) ÷ 3((-1 × 1) - 0 × 1) - 1((-1 × 1) - 1 × 1) + 0(1 × 0 + 1 × 1)

= (-82 + 58 + 0)/(-3 + 2 + 0)

=  -24/-1

= 24

n₂ =

[tex]det\left[\begin{array}{ccc}3&82&0\\1&38&1\\1&20&-1\end{array}\right] /det\left[\begin{array}{ccc}3&1&0\\1&1&1\\1&0&-1\end{array}\right][/tex]

= 3((38 × -1)- (20 × -1)) - 82((-1 × 1) - 1 × 1)  + 0(20 × 1 - (38 × 1) ) ÷ 3((-1 × 1) - 0 × 1) - 1((-1 × 1) - 1 × 1) + 0(1 × 0 + 1 × 1)

= (-174 + 164 + 0)/(-3 + 2 + 0)

=  -10/-1

= 10

n₃ =  

[tex]det\left[\begin{array}{ccc}3&1&82\\1&1&38\\1&0&20\end{array}\right] /det\left[\begin{array}{ccc}3&1&0\\1&1&1\\1&0&-1\end{array}\right][/tex]

= 3((1 × 20)- (0 × 38)) - 1((1 × 20) - 1 × 38)  + 82(1 × 0 - (1 × 1) ) ÷ 3((-1 × 1) - 0 × 1) - 1((-1 × 1) - 1 × 1) + 0(1 × 0 + 1 × 1)

= (60 + 18 - 82)/(-3 + 2 + 0)

=  -4/-1

= 4

So, Inter milan had 24 wins, 10 draws and 4 losses.
