Answer:
60
Step-by-step explanation:
So we have all four side lengths: 8, 3, 10, and 9. Since there's one diagonal side, the best way to solve this is to split the shape in two. So the area of the first shape would be 24 because 8 x 3 is 24. The other one would be different. The side length is 8, so we multiply 9 by 8 and get 72. But since it's a triangle, we have to divide that by 2. Then we get 36. If you add 36 and 24, you get 60. That would be your area.

In triangle XYZ, XY¯¯¯¯¯¯¯¯=15, YZ¯¯¯¯¯¯¯=8, ∡X=(3w−35)°, and ∡Y=52°. In triangle RST, RS¯¯¯¯¯¯¯=15, RT¯¯¯¯¯¯¯=8, ∡R=(w+17)°, and ∡S=52°. Find the angle measure for each of the four angles whose measures are not known.
A. ∡R=43°, ∡T=85°, ∡X=43°, ∡Z=85°
B. ∡R=64°, ∡T=64°, ∡X=64°, ∡Z=64°
C. ∡R=35°, ∡T=93°, ∡X=35°, ∡Z=93°
D. ∡R=52°, ∡T=76°, ∡X=52°, ∡Z=76°
Answer:
A. ∡R=43°, ∡T=85°, ∡X=43°, ∡Z=85°
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Cosine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:
[tex]a^2=b^2+c^2-2bc*cos(A)[/tex]
In triangle XYZ, we can find XZ using cosine rule:
[tex]XZ^2=XY^2+YZ^2-2(XY)(YZ)cosY\\\\subtituting:\\\\XZ^2=15^2+8^2-2(15)(8)cos(52)\\\\XZ^2=141.24\\\\XZ=11.88\\\\Using\ sine\ rule:\\\\\frac{XZ}{sin(Y)}=\frac{XY}{sin(Z)}\\\\\frac{11.88}{sin(52)}=\frac{15}{sin(Z)}\\\\sin(Z)=15*sin(52) /11.88\\\\sin(Z)=0.9946\\\\Z=sin^{-1}(0.9946)\\\\Z=85^0[/tex]
∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
∠X + 52 + 85 = 180
∠X + 137 = 180
∠X = 43°
∠X = 3w - 35
3w - 35 = 43
3w = 78
w = 26
In triangle RST, using sine rule:
∠R = w + 17
∠R = 26 + 17
∠R = 43°
∠R + ∠S + ∠T = 180° (sum of angles in a triangle)
43 + 52 + ∠T = 180
∠T + 95 = 180
∠T = 85°

Question Help
Writing Ann's car can go 238 miles on 7 gallons of gas. During a drive last weekend, Ann used
8 gallons of gas. How far did she drive? Use pencil and paper. Explain how the problem changes
if you were given the distance Ann drove last weekend instead of how much gas she used.
Answer:
272
Step-by-step explanation:
do 238 divided 7 you get 34 then you multiply it by 8
Given :
Writing lan's car can go 238miles on 7 gallons of gas.
During a drive last weekend, lan used
8 gallons of gas.
To find :-
How far did he drive?
Solution :-
According to Question ,
Car can go 238 mi on 7 gallons of gas.
Using Unitary Method ,
On 1 gallon of gas it will go 238/7 mi
On 8 , it will go 238/7*8= 272miles
Hence the required answer is 272 miles.
Find 18.5% of 500- I couldn’t seem to figure this one out for some reason I dunno
Answer:
92.5
Step-by-step explanation:
18.5
[tex] \frac{18.5}{100} \times 500 \\ \\ [/tex]
100 times 5 is 500
so 100 is cancelled and 500 becomes 5
therefore 18.5 times 5 is equal to 92.5
Answer:
92 1/2 or 92.5
Step-by-step explanation:
how to solve?
Put it into a percent proportion :D!
Percent proportion is is/of=%/100 or a/w=p/100
The a stands for "part"
and the w stands for "whole"
p stands for "percent"
Is/of=%/100 will help you figure it out if it's in a mathmatical sentence.
Since they did NOT give you what the "is" is, you put the variable "a"
a/ =
Next,
Since it said "of"
You put of underneath the unknown number "is" (a)
a/500=
Now put in the percent
a/500=18.5/100
Now cross multiply!
Then you should get 92.5!

Can anyone give me the awnser?
Answer:
Step-by-step explanation:
You want to reverse the algebra and solve for y. First you want to subtract the 'a' to both sides.
x - a = -2by^2
Divide by -1 on both sides
-x + a = 2by^2
Divide by 2b on both sides
(-x + a)/2b = y^2
Take the square root of both sides
[tex]\sqrt{(-x+a)/2b}=y[/tex]

Write an equation for the line that is
perpendicular to the x-axis at the point (5,0). What
is the slope of the line?
Answer:
x = 5
Step-by-step explanation:
A perpendicular line that passes through the point (5, 0) is a vertical line in which all points have 5 as their x-coordinate.
The slope is undefined since the slope of all vertical lines is undefines.
Answer: x = 5
Answer:
equation: y = 5
slope is zero

Answer:
Yes, Suri and Juan can make the same amount of wages by working the same number of hours in one week.
Step-by-step explanation:
The equation to figure out how many hours they will have to work is:
15x+25=14x+50
x=25
Now that we know that they have to work 25 hours, we substitute that in for x and that equals $400.

There is a guitar that originally costs $249.99. It is on sale for 15% off. You also have to pay 6% sales tax. How much will you pay for the guitar? Please show work!!!
Answer:
225.24099
Step-by-step explanation:
249.99(0.15) = 37.4985
249.99 - 37.4985 = 212.4915
212.4915(0.06) = 12.74949
212.4915 + 12.74949 = 225.24099

A full glass of water can hold 1/6 of a bottle.
How many glasses of water can be filled with 3 1/2. bottles of water?
Answer:
21 glasses
Step-by-step explanation:
6 glasses in a bottle
3 x 6 = 18
3 glasses in half a bottle
18 + 3 = 21
Answer:
21 glasses
Step-by-step explanation:
let 'g' = glasses of water
create a proportion, glasses over bottles equals glasses over bottles
1 = g
1/6 7/2
cross-multiply: 1/6g = 7/2
cross-multiply: 2g = 42
g = 21

Find the length of side BC.
Give your answer to 3 significant figures.
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )
