Answer:

[tex]\theta \:=43.76^{\circ \:\:}[/tex]

Step-by-step explanation:

The right triangle has the hypotenuse = 18

Let 'Ф' be the missing angle

we know that

cos Ф = adjacent/hypotenuse

Here,

so

cos Ф = adjacent/hypotenuse

[tex]cos\:\theta \:=\frac{13}{18}[/tex]

[tex]\theta \:=\cos ^{-1}\left(\frac{13}{18}\right)[/tex]

   [tex]=43.76^{\circ \:}[/tex]

Therefore, the missing angle is:

[tex]\theta \:=43.76^{\circ \:\:}[/tex]

Answer:

50

Step-by-step explanation:

2(Mr stack's speed) = Coach Pugh's speed - 5mph

Mr stack's speed = (105mph - 5mph)/2

Mr stack's speed = 100mph/2

Mr stack's speed = 50mph

Answer:

[tex]12-20x^{2}[/tex]

Step-by-step explanation:

[tex]4(3-5x^{2}) = (4*3)-(4*5x^{2} )[/tex]

[tex]4*3 = 12[/tex]

[tex]4*5x^{2} =20x^{2}[/tex] since you only multiply the numbers

[tex]12-20x^{2}[/tex]

Answer:

B. 9

Step-by-step explanation:

3^4/3^2

lets expand it

3 * 3 * 3 * 3/ 3 * 3

just get rid the 3's needed to get rid of the denominator which is 2, so get rid of 2 threes from the top

3 * 3 = 9

And it's okay, I dislike math too. Hope you feel better.

Answer:

Step-by-step explanation:

D

The answer is a. y=6 :)

Answer:

1) Simple interest is 72 dinars

2) Total amount after 3 years is 672 dinars.

Step-by-step explanation:

Principal Amount P = 600 dinars

Interest Rate= 4% = 0.04

Time = 3 years

i) Simple Interest

The formula used to calculate interest is [tex]I=P\times r \times t[/tex]

Putting values and finding interest

[tex]I=P\times r \times t\\I=600\times 0.04 \times 3\\I=72[/tex]

So, simple interest is 72 dinars

ii) Total amount after 3 years ​

The formula to calculate total amount is: [tex]A=P(1+rt)[/tex]

Putting values and finding future amount A

[tex]A=P(1+rt)\\A=600(1+(0.04*3))\\A=600(1+0.12)\\A=600(1.12)\\A=672[/tex]

So, Total amount after 3 years is 672 dinars.

Answer:

150

Step-by-step explanation:

25x6=150

25x5=125

150-125=25

Answer:

option A, 1/8

Step-by-step explanation:

[tex]\frac{3}{8}[/tex] × [tex]\frac{1}{2}[/tex] × [tex]\frac{2}{3}[/tex]

⇒  3 × 1 × 2/8 × 2 × 3

⇒ 6/48

⇒ 1/8

therefore, option A is the correct option

Answer:

A. 1/8

Step-by-step explanation:

56 mm = 5.6 cm since there are 10 mm in a cm, so we divide by 10 to go from mm to cm.

Since the diameter is 5.6 cm, this means 12 such cans lead to 12*5.6 = 67.2 cm of length needed to house 12 cans along this row.

Similarly, if we had 6 cans along each column, then 6*5.6 = 33.6 cm is needed for this

The diagram below shows what I mean. This diagram is a top-down view of the box. In other words, it's a birds-eye view.

The last dimension we need to take care of is the height of the box. That would be 2*5.6 = 11.2 cm since there are 2 cans along the height

Therefore, the smallest box possible has dimensions of 67.2 cm by 33.6 cm by 11.2 cm

You could have bigger boxes of course, though you'll need to place cushions inside so the cans don't rattle around. The smallest box dimensions listed above are ideal to avoid wasting too much cushion material (you'll still may need some form of cushion though just not as much).

Answer:

First is 5/2

second is 1

Answer:

1. A. slope = 5/2

2. A. slope = 1

Step-by-step explanation:

To find the slope you can input the x and y values of two points into this expression: [tex]\frac{y2 -y1}{x2 - x1}[/tex]

1. To find the slope, I'm going to use points (2, 3) and (4, 8). Let's input them into the expression:

[tex]\frac{8-3}{4-2}[/tex]

Simplify:

8 - 3 = 5

4 - 2 = 2

The slope is 5/2.

2. To find the slope, I'm going to use points (0, 0) and (1, 1). Let's input them into the expression:

[tex]\frac{1-0}{1-0}[/tex]

Simplify:

1 - 0 = 1

1 - 0 = 1

The slope is 1/1, or just 1.

Step-by-step explanation:

It's really not that hard

Answer:

25% decreased by 60% is 10

Step-by-step explanation:

New value =

25 - Percentage decrease =

25 - (60% × 25) =

25 - 60% × 25 =

(1 - 60%) × 25 =

(100% - 60%) × 25 =

40% × 25 =

40 ÷ 100 × 25 =

40 × 25 ÷ 100 =

1,000 ÷ 100 = 10

hope this helps :)

I'm not even sure if this helps but it factored

Answer:

  107.5° and 72.5°

Step-by-step explanation:

  x + y = 180          same side interior angles of two parallel lines add up to 180

  x - y = 35            

___________

     2x = 215                           add above two equations

       x = 107.5°                       divide by 2 to isolate x

Substitution to find y:

  x + y = 180

  107.5 + y = 180

              y = 72.5°

The measure of these two angles is 107.5° and 72.5°.

Given that,

Based on the above information, the calculation is as follows:

x + y = 180          

And,

x - y = 35            

So, after solving it, it comes

2x = 215                            

x = 107.5°                  

So, y = 180 - 107.50 = 72.5

Therefore we can conclude that the measure of these two angles is 107.5° and 72.5°.
