Answer:
Area of trapezoid = 200 m²
Step-by-step explanation:
Parallel side1 a= 15m
Parallel side2 b= 25m
Perpendicular distance h = 10 m
We need to find area of the trapezoid.
The formula used to find area of the trapezoid is: [tex]Area \ of \ trapezoid=\frac{a+b}{2}h[/tex]
Putting values and finding area of the trapezoid:
[tex]Area \ of \ trapezoid=\frac{a+b}{2}h\\Area \ of \ trapezoid=\frac{15+25}{2}\times 10\\Area \ of \ trapezoid=40\times5\\Area \ of \ trapezoid=200 \ m^2[/tex]
So, area of trapezoid = 200 m²

Find the measure of the indicated angle to the nearest degree
Answer:
23°
Step-by-step explanation:
Using trigonometry and the Soh Cah Toa method you can find this. Because you are looking for an angle you have to use the inverse and because it is adjacent and hypotenuse you use cosine. So take cos*-1( 35/38) because 35 is the adjacent and 38 is the hypotenuse.

Austin is 69 years younger than Jamie. 3 years ago, Jamie's age was 4 times Austin's age. How old is Austin now?
Answer: 26 years old
Step-by-step explanation:
Create an equation with Austin as x and Jamie as x+69 (I just like workin with addition signs more)= 4(x-3)= x+69-3Simplify the equations --> 4x-12=x+66Solve the equation: 3x-12=66 --> 3x=78 --> x=26This is the same as other age problems, just with the extra step of distributing the multiplication.

The ratio of females to total students in a mathematics class is 18 to 30. What fraction of the class is male? What percent is male?
Answer:
2/5 or 40%
Step-by-step explanation:
total students=30
female students=18
That must mean, assuming the rest of the class is binary male=12
12/30=2/5 or 40% if you multiply by 20, then multiply by 100%
(2/5)*20=.40*100%=40%

I think the question is 2x/4 - 1/3 + x = 2
So, if I solve for this:
[tex] \frac{2x}{4} - \frac{1}{3} + x = 2[/tex]
[tex] \frac{x}{2} - \frac{1}{3} + x = 2[/tex]
[tex] \frac{3x}{6} - \frac{2}{6} + \frac{6x}{6} = 2 [/tex]
[tex] \frac{3x - 2 + 6x}{6} = 2[/tex]
[tex]\frac{(3x + 6x) - 2}{6} = 2[/tex]
[tex] \frac{9x - 2}{6} = 2[/tex]
[tex]9x - 2 = 2 \times 6[/tex]
[tex]9 x - 2 = 12[/tex]
[tex]9x = 12 + 2[/tex]
[tex]9x = 14[/tex]
[tex]x = \frac{14}{9} [/tex]
Cynthia is training to run the 100 yard dash. The first week she ran it is 14.0 seconds. The third week she ran it in 13.1 seconds. What is the percent change from week 1 to week 3 rounded to the nearest tenth of a percent?
Answer:
6.43% change
Step-by-step explanation:
Have a good one
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
The percent change from week 1 to week 3 rounded to the nearest tenth of a percent is 6.4%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
First week:
Time taken to run 100 yards = 14 seconds
Third week:
Time taken to run 100 yards = 13.1 seconds
The percentage change in the time from the first week to the third week:
= [(Time taken at the first week - Time taken at the third week) / Time taken at the first week ] x 100
= [(14 - 13.1) / 14] x 100
= 0.9/14 x 100
= 6.4%
This means that there is 6.4% from the first week to the third week.
Thus,
The percent change from week 1 to week 3 rounded to the nearest tenth of a percent is 6.4%.

Mary is five times as old as Fred. In three years Mary will be 4 times as old as Fred. Find their present ages?
ans
here let mary age be x and fred be y
1st equation
x= 5y
2nd equation
x+3 =4(y+3)
now from 1st equation putting value of x in equation 2
x+3 = 4y+12
5y+3 = 4y +12
y = 9

AC congruent to DF because AC = 13.5 in. and DF = 13.5 in, EF congruent to BC because EF = 12 in. and BC = 12 in., ∠C congruent to ∠F. The triangles ACB and DEF congruent by the SAS Triangle Congruence Theorem only when x = 7
Step-by-step explanation:
If two sides in a triangle congruent to two sides in other triangle and the including angles between the two sides are congruent in the triangles, then the two triangles are congruent by the SAS postulate of congruency
In the given figure
→ If ∠C ≅ ∠F
∵ m∠C = m∠F
∵ m ∠ C = (2x + 14)°
∵ m∠F = (4x)°
→ Equate them to find x
∴ 4x = 2x + 14
→ Subtract 2x from both sides
∴ 2x = 14
→ Divide both sides by 2
∴ x = 7
→ In Δs ABC and DEF
∵ AC congruent to DF because AC = 13.5 in. and DF = 13.5 in
∵ EF congruent to CB because EF = 12 in. and CB = 12 in.
∵ ∠C congruent to ∠F
∴ The triangles ACB and DEF congruent by the SAS Triangle Congruence

The number of candles sold in the second week is 240 candles
What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Number of cases sold on first week = 7 cases
Number of candles in each case = 40 candles
Total cases of candles to be sold = 13 cases
Remaining cases of candles to be sold in second week =
Total cases of candles to be sold - Number of cases sold on first week
Remaining cases of candles to be sold in second week = 13 - 7
= 6 cases
Therefore , number of candles in 6 cases = 6 x 40
= 240 candles
Hence , the number of candles sold in the second week is 240 candles
