Answer:
5. x = 9
6. x = 12
7. x = 15
8. x = 11
Step-by-step explanation:
5. 90-56 = 34
34 = 3x + 7
27 = 3x
x = 9
6. 90 - 48 = 42
42 = 3x + 6
36 = 3x
x = 12
7. 90 - 47 = 43
43 = 2x + 13
30 = 2x
x= 15
8. 3x + 5x + 2 = 90
8x = 88
x = 11

What is the lateral surface area of this triangular prism in square centimeters?
Answers
Answer:
lateral surface area of the triangular prism = 128 cm²
Step-by-step explanation:
The question is incomplete the picture below represents the complete question.
Lateral surface area of a triangular prism = PH
where
p = perimeter of the triangle
H = height of the prism
perimeter = 5 + 5 + 6 = 16 cm
height of the prism = 8 cm
Lateral surface area of a triangular prism = Perimeter of the triangle × height of the prism
lateral surface area of the triangular prism = 16 × 8
lateral surface area of the triangular prism = 128 cm²

In 2010 Harry bought 200 shares in ford motors company stock for 35.21 per share in 2018 he sold the shares for 26.78 each express his capital loss as a percent
Answers
Answer:
23.94%
Step-by-step explanation:
In 2010, Harry bought 200 shares in ford motors company stock for $35.21 per share. This means that the cost price of buying the 200 shares is:
C = 200 * 35.21 = $7042
In 2018, he sold the shares for $26.78 per share. The selling price of 200 shares is:
S = 200 * 26.78 = $5356
The loss is given as the cost price minus selling price. That is:
L = CP - SP
L = 7042 - 5356
L = $1686
Percentage loss is given as loss divided by cost price multiplied by 100:
%L = 1686 / 7042 * 100
%L = 23.94%

A skate board was originally priced at £100 on Thursday.
On Friday the price was reduced by 50%. On Saturday, Friday's price was reduced by a further 30%. On Sunday, Saturday's price was reduced by a final 10%.
What was the final percentage reduction on the original price?
Answers
Answer:
31.5
Step-by-step explanation:
50 percent of 100 would be 50, so you subtract 50 from 100, and 30 percent of 50 is 15, so you subtract 15 from 50 and then get 35, which 10 percent of is 3.5, and finally you subtract 3.5 from 35 and you end up with 31.5.

Formula to find the surface area of a triangular prism
Answers
Step-by-step explanation:
In the mensuration of a triangular prism we can find the total surface area by solving for the areas of individual shape.
The triangular prism consist of
1. three rectangular surfaces
2. two triangular surfaces.
Hence the total surface area is the sum of the areas of the rectangular surface
= [tex](l* w) +( l*w)+(l*w)\\[/tex]
and the sum of all areas of triangular surfaces
= [tex](\frac{1}{2}bh) + (\frac{1}{2}bh)[/tex]
In summary just find the area of each shape and add them together.
A bag contains 2 red, 5 blue, and 7 yellow marbles. Find the probability of drawing a yellow or a red.
Answers
Answer:
drawing a red marble would be 2 in a 14 or 1/7 chance n drawing a yellow would be 1/2.
The probability of drawing a yellow marbles is 1/2
What is probability ?Probability means the quality or state of being probable; the extent to which something is likely to happen or be the case
We have,
Bag contains marbles
Red=2
Blue=5
Yellow=7
Total marbles in bag = 2+5+7=14
The total number of ways of selecting one marble out n(s) = 14[tex]C_{1}[/tex]
= 14 ways
Let E be the event of selecting yellow marbles
Since, the bag contains 7 yellow marbles
one yellow marble can be draw from 7 yellow n(E) =7[tex]C_{1}[/tex]
= 7 ways
We know the formula,
P(E)= n(E)/n(s)
= 7/14
= 1/2
Hence, the probability of drawing a yellow marbles is 1/2

Two angles are supplementary. If the m∠A is five times the sum of the m∠B plus 7.2°, what is m∠B?
Answers
Answer:
m∠B = 24°
Step-by-step explanation:
m∠A + m∠B = 180°
m∠A = 5 ( m∠B + 7.2 )
5 ( m∠B +7.2 ) + m∠B = 180
5m∠B + 36 + m∠B = 180
6m∠B = 180 - 36
6m∠B = 144
m∠B = 24°

Answers
Answer:
[tex]v \approx 415.2\,cm[/tex]
Step-by-step explanation:
The angle T is:
[tex]\angle T = 180^{\circ} - 27^{\circ} - 78^{\circ}[/tex]
[tex]\angle T = 75^{\circ}[/tex]
Now, the length of v is determine by the Law of Sines:

[tex]v = (410\,cm)\cdot \left(\frac{\sin 78^{\circ}}{\sin 75^{\circ}} \right)[/tex]

Use right triangle ABC. The figure is for reference only and is not drawn to scale. In a 30-60-90 triangle, the shorter leg had a length of 8. What is the length of the longer leg?
Answers
Answer:
In a 30 60 90 triangle, the longer leg = shorter leg * square root (3)
longer leg = 8 * square root (3) = 8 * 1.7320508076

You are measuring the height of a Ferris wheel at an amusement
park. You are standing 125 feet from its base. You measure the angle
of elevation from a point on the ground to the top of the Ferris wheel
to be 51°. Estimate the height of the Ferris wheel. Round your
answer to the nearest foot.
Answers
Answer:
154 ft
Step-by-step explanation:
A right triangle is formed, where the height of the wheel (h) is one leg, the distance between you and the base of the wheel is the other leg, and the distance between you and the top of the wheel is the hypotenuse (the angle included between the last two sides is 51°)
From definition:
tan(51°) = opposite/adjacent
tan(51°) = h/125
h = tan(51°)*125
h = 154 ft
