sorry if wrong..One angle of a parallelogram measures 125 degrees. What are the measures of the other three angles in the parallelogram?
Answer:
55°, 55° and 125°
Step-by-step explanation:
Opposite angles of a parallelogram are congruent, then
Angle opposite 125° is also 125°
Consecutive angles are supplementary, sum to 180°, then
consecutive to 125° is 55°
sngle opposite 55° is also 55°
The other 3 angles are 55°, 55° and 125°

how do i solve 13 + a/11 = 7
Answer:
a = -66
General Formulas and Concepts:

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityStep-by-step explanation:
Step 1: Define
13 + a/11 = 7
Step 2: Solve for a
Subtract 13 on both sides: a/11 = -6Multiply 11 on both sides: a = -66Step 3: Check
Plug in a into the original equation to verify it's a solution.
Substitute in a: 13 - 66/11 = 7Divide: 13 - 6 = 7Subtract: 7 = 7Here we see that 7 does indeed equal 7.
∴ a = -66 is the solution to the equation.
Answer:
If you mean [tex]\frac{13+a}{7}=7[/tex] then the answer is [tex]a=36[/tex].
If you mean [tex]13+\frac{a}{7} =7[/tex] then the answer is [tex]a=-42[/tex].
Step-by-step explanation:
To do this question, you simplify both sides of the equation and then isolate the variable.

Lucy and Greg each want to buy a bicycle. Lucy has already saved $35 and plans to save $10 per week. Greg has $26 and plans to save $13 per week. How many weeks will it take for Lucy and
Gregory to have the same amount of money saved? How much money will they have saved?
Answer:
3 weeks
65 dollars
Step-by-step explanation:
Alright to answer this question we have to set up an equation. For greg the equation is y=13x+26 and for lucy the equation is y=10x+35. y is total amount of money saved and x is number of weeks. Since we want them to each of the same amount of money we set up the equations to be 10x+35=13x+26
then we want to get the constant and the variables alone on different sides of the equal sign so we first subtract 26 from each side to get 10x+9=13x. next we want to subtract 10x from each side and then we end up with 3x=9. Finally we divide 3 from each side to get x=3, We have answered the question to how many week it will take them to save the same amount of money but not the other part. To find out how much money they will both have in 3 weeks we plug in 3 to x. 10(3)+35 which is equal to 65. They will both have 65 dollars in three weeks
Ella was paid an 11 percent commission on the pair of shoes that she sold. The department store had paid $25 wholesale for the shoes and had marked up the price by 40 percent to the selling price. How much did Ella earn for the sale?
Answer:
The answer is B. $3.85.
Step-by-step explanation:
This is because, first if we get the percentage that the shoes were marked up by, we get that they were marked up to $35, because 40% of $25 is $10 and $25 + $10 = $35.
Then, we find the percentage of $35 that she earned. In order to do this, we see what 11% of $35 is. We get $3.85, because 10% of $35 is $3.50, and 1% of $35 is $0.35. $3.50 + $0.35 = $3.85.
This is why the answer is B. $3.85.

X = 129 degrees
Malcolm Little High School has sopho- mores, juniors, and seniors, but no freshmen. The ratio of sophomores to juniors is 5 to 4, and the ratio of juniors to seniors is 3 to 2. If there are 300 sophomores, how many seniors are there?
Answer:
161 seniors
Step-by-step explanation:
According to the problem, given data are as follows:
Total number of sophomores = 300
Sophomores to junior ratio = 5:4
So, Number of Juniors = 300 × (4 ÷ 5)
= 240
Now, Juniors to senior ratio = 3:2
So, we can calculate the number of seniors by using following method:
Number of seniors = 240 × ( 2 ÷ 3)
= 240 × 0.67
= 160.8 or 161

Find the area of the shaded regions. Give your answer as a COMPLETELY simplified EXACT VALUE OF π (no approximations).
Answer:
128π - 8
Step-by-step explanation:
Hypotenuse length:
4² + 4² = 32
2π(√32/2)² = (√32)² × 2² = 2π × 32 × 4 = 2π × 128
256π is the area of the circle
Area of shaded region = area of circle/2 - area of triangle
256π/2 = 128π
128π - 16/2
128π - 8 = area of shaded region

The greatest common factor of two numbers is 4. The sum of the numbers is 76. What are the two numbers? A. 38 and 38 B. 12 and 64 C. 18 and 58 D. 32 and 40
Answer: B. 12 and 64
Step-by-step explanation:
Option A is incorrect because the highest common factor for both numbers would be 38 not 4.
Option B:
Factors of 12 are: 1, 2 , 3, 4, 6, 12
Factors of 64 are: 1, 2, 4, 8, 16, 32 and 64.
Highest factor of both is 4 and they both add up to 76 so option B must be correct.

F is inversely proportional to d squared. When F = 16 , d = 3 Work out d (positive value rounded to 2 DP) when F = 8
Answer:
d = 3√2
Step-by-step explanation:
find the constant of variation ('k'): F = k/d²
16 = k/3²
16 = k/9
k = 144
8 = 144/d²
d² = 144/8
d² = 18
d = √9 · √2
d = 3√2
