Answer:
The answer is A.
Step-by-step explanation:
We know two sides, and one angle of the corresponding side. Thus, we can use the Law of Sines to find the last angle.
The Law of Sines:
[tex]\frac{sin(A)}{A}=\frac{sin(B)}{B}= \frac{sin(C)}{C}[/tex]
Plug in what we know:
[tex]\frac{sin(38)}{70} =\frac{sin(C)}{108}[/tex]
Cross multiply:
[tex]70sin(C)=108sin(38)[/tex]
[tex]sin(C)=\frac{108sin(38)}{70}[/tex]
[tex]C=arcsin(\frac{54sin(38)}{35} )[/tex]
[tex]C \approx 71.7827[/tex]

What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
From observation, it is given that the line segment MN which joins points M and N is parallel to the line JK. which follows from the fact that M and N are midpoints of KL and JL respectively.
Hence, it states that triangles NLM and JLK are congruent and by the ratio of corresponding sides equality:
NM/19.6 = 7.4/(2×7.4)
Solving;
NM = 19.6/2
NM= 9.8 meters.
This follows that, the ratio of corresponding sides of congruent triangles are equal.
The distance between points M and N is; 9.8 meters.

What is the total volume of snow used to make the snowman if the head is 12 inches wide, the middle is 16 inches wide,and the bottom is 18 inches wide
Answer:
726.65 cubic inches
Step-by-step explanation:
We are going to assume that the head, middle and bottom are spheres.
The formula to get the volume of a sphere is
[tex]V= \frac{4}{3}\pi r^{2}[/tex] where r is the radius of the sphere.
Now, let's proceed to apply this formula to the 3 spheres of the snowman:
The head is 12 inches wide (diameter), thus, the radius would be 6 inches:
[tex]V= \frac{4}{3}\pi r^{2}\\V= \frac{4}{3}\pi 6^{2}\\V= \frac{4}{3}\pi 36\\V=\frac{144\pi }{3} \\V=38\pi[/tex] cubic inches
The middle is 16 inches wide (diameter), thus, the radius would be 8 inches.
[tex]V= \frac{4}{3}\pi r^{2}\\V= \frac{4}{3}\pi 8^{2}\\V= \frac{4}{3}\pi 64\\V=\frac{256\pi }{3} \\V=85.3\pi[/tex] cubic inches
The bottom is 18 inches wide (diameter), thus the radius would be 9 inches.
[tex]V= \frac{4}{3}\pi r^{2}\\V= \frac{4}{3}\pi 9^{2}\\V= \frac{4}{3}\pi 81\\V=\frac{324\pi }{3} \\V=108\pi[/tex] cubic inches.
Now, to get the total volume of the snowman we're going to sum up the volume of all three spheres:
Total volume = [tex]38\pi +85.3\pi +108\pi =231.3\pi[/tex] cubic inches.
If we take pi = 3.1416,
Total volume = [tex]231.3(3.1416)=726.65[/tex] cubic inches.
Allie has 10.25 in quarters and dimes.. how many dimes does she have
Answer:
(Depending on the available answers) Allie has 37 quarters and 10 dimes.
Step-by-step explanation:
37 quarters add up to $9.25 (37 x 0.25 = 9.25). 10 dimes add up to $1 (10 x 0.10 = 1). 37 quarters and 10 dimes add up to $10.25. There are other ways you can divide $10.25 into quarters and dimes (such as 21 quarters and 50 dimes) but this is just one of them. I hope this helped, good luck on your test/work!

What is an equation in point-slope form of the line that passes through (1, -6) and (4, 6)?
Answer:
[tex]y+6=4(x-1)[/tex] or [tex]y-6=4(x-4)[/tex]
Step-by-step explanation:
We want to find the equation in point-slope form of the line that passes through the two points (1, -6) and (4, 6).
Recall that point-slope form is given by:
[tex]y-y_{1}=m(x-x_{1})[/tex]
Where m is the slope.
Find the slope m using the two given points.
[tex]\displaystyle m = \frac{\Delta y}{\Delta x} = \frac{6-(-6)}{4-1} = \frac{12}{3} = 4[/tex]
Substitute. We can use either point. Using the point (1, -6), we acquire:
[tex]y-(-6)=4(x-(1))[/tex]
Simplify:
[tex]y+6=4(x-1)[/tex]
And using the point (4, 6), we acquire:
[tex]y-(6)=4(x-(4))[/tex]
Simplify:
[tex]y-6=4(x-4)[/tex]
For every pound a company spends on advertising, it spends £0.75 on its website. Express the amount spent on advertising to the amount spent on its website as a ratio in its simplest form.
Answer:
the ration to the money spend on ads to website is 4:3
The amount spent on advertising to the amount spent on its website as a ratio in its simplest form is: 4: 3
Given that:
For every pound, the company spends on advertising i.e. £1the company spends £0.75 on its website.Thus, the ratio of the amount spent on the advertising and the website is computed as:
£1: £ 0.75
Since a ratio can be expressed in a fraction when solving to its simplest form, then we have:
[tex]\mathbf{\dfrac{1}{0.75}}[/tex]
Let's multiply both the numerator and the denominator by 100 to shift the decimal in two places in 0.75
Then, we have:
[tex]\mathbf{=\dfrac{1\times 100}{0.75 \times 100}}[/tex]
[tex]\mathbf{=\dfrac{ 100}{75 }}[/tex]
Divide both sides by 5;
[tex]\mathbf{=\dfrac{ 20}{15 }}[/tex]
Divide both sides by 5;
[tex]\mathbf{\dfrac{4}{3}}[/tex]
Therefore, the amount spent on advertising to the amount spent on its website in ratio is 4:3

This figure is made up of a triangle and a semicircle. What is the area of this figure? Use 3.14 for pi. Round only your final answer to the nearest tenth. Enter your answer, as a decimal, in the box
Answer:
Area = 14.8 units²
Step-by-step explanation:
Base of Triangle = 2 units
Height of Triangle = 5 units
Radius of the semi circle = 2.5 units
Now,
Triangle:
Area of triangle = 1/2(base*height)
Area = 1/2(2*5)
Area = 1/2(10)
Area = 5 units²
Semi-Circle:
Area of semi-circle = 1/2(πr²)
Area = 1/2(3.14)(2.5)²
Area = 1/2(3.14)(6.25)
Area = 9.8 units²
Area of the figure:
Area = 5 + 9.8
Area = 14.8 units²

A thirty-five ounce bottle of Pedialyte contains 2,500 mg of dextrose. If a child drinks 7 ounces straight from the bottle, how many mg of dextrose will he consume?
Answer:
500 mg
Step-by-step explanation:
amount of dextrose in 35 ounce Pedialyte = 2500 mg
dividing LHS and RHS by 35
amount of dextrose in 35/35 ounce Pedialyte = 2500 /35 mg = 500/7 mg
Thus,
amount of dextrose in 1 ounce Pedialyte = 500 /7 mg
since we have to find amount of dextrose in 7 ounce Pedialyte
we multiply LHS and RHS by 7
Thus,
amount of dextrose in 1 *7 ounce Pedialyte = 500 /7 * 7 mg = 500 mg
amount of dextrose in 7 ounce Pedialyte = 500 mg
Thus, As child consumed 7 ounces of Pedialyte, He consumed 500 mg of dextrose.
find the total surface area of this triangular prism
Answer:
144 cm²
Step-by-step explanation:
There are five total sides to the triangular prism. The formula for the area of a rectangle is length · width. The formula for the area of a triangle is 1/2 base · height.
10 · 4 = 40
6 · 4 = 24
8 · 4 = 32
1/2(6 · 8) = 48/2 = 24
1/2(6 · 8) = 48/2 = 24
Add the surface area for each side to get the total surface area.
40 + 24 + 32 + 24 + 24 = 144 cm²

(A) 2
(B)1/2
(C) -1/2
(D) –2
Answer:
Option B

=> 2(1/4)+7/2-4
=> 1/2+7/2-4
=> [tex]\frac{1+7-8}{2}[/tex]
=> [tex]\frac{8-8}{2}[/tex]
=> 0
Yes, This is the zero of the polynomial having zero as an answer

En una pizzeria se hicieron 8 docenas de pizzas. La tercera parte se vendio en el local y las cinco octavas partes son para enviar a domicilio ¿cuantas pizzas se vendieron en el local? ¿y cuantas pizzas se vendieron a domicilio? ¿que parte de las pizzas quedo sin vender?
Answer:
32 pizzas
60 pizzas
1/24
Step-by-step explanation:
Se hicieron 8 docenas de pizzas.
Una docena es 12, por lo tanto, el número de pizzas hechas fue:
8 * 12 = 96 pizzas
1/3 se vendieron en el local, esto significa que el número de pizzas vendidas en el local es:
1/3 * 96 = 32 pizzas
5/8 fueron para entrega a domicilio, por lo tanto, el número de pizzas vendidas en casa es:
5/8 * 96 = 60 pizzas
El número total de pizzas vendidas es:
32 + 60 = 92 pizzas
Esto significa que no se vendieron 4 pizzas. En forma de fracción:
4/96 = 1/24
