Triangle D E F is shown. Angle D E F is 140 degrees. The length of D E is 11, the length of E F is 9, and the length of D F is e.
In ΔDEF, DE = 11, EF = 9, and angle E = 140°.
Which equation correctly uses the law of cosines to solve for the third side?
e2 = 112 + 92 − 2(11)(9)cos(140°)
112 = e2 + 92 − 2e(9)cos(140°)
92 = e2 + 112 − 2e(11)cos(140°)
e = 11 + 9 − 2(11)(9)cos(140°)
Answer:
e2 = 112 + 92 − 2(11)(9)cos(140°)

Francis earns a weekly salary of $475 plus a 5.5% commission on sales at a girt shop. How much would he earn in a week if he sold $700 in goods? *
Given:
Francis earns a weekly salary of $475 plus a 5.5% commission on sales at a girt shop.
To find:
How much would he earn in a week if he sold $700 in goods?
Solution:
We have,
Fixed weekly salary = $475
Commission percentage = 5.5% on sales.
Total sales of goods = $700
Total commission = 5.5% of 700
[tex]=\dfrac{5.5}{100}\times 700[/tex]
[tex]=5.5\times 7[/tex]
[tex]=38.5[/tex]
Now,
Total weekly salary = Fixed weekly salary + Commission
[tex]=475+38.5[/tex]
[tex]=513.5[/tex]
Therefore, the total weekly salary is $513.5.
A soccer team won 11 games last year. This year they won 13 games. What was the percent increase in the number of games won? Round your answer to the nearest whole percent.

What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , length of side AC is 10 and the length of CB is 13.
Angle BAC is 64° and angle ACB is 72°
Now , the area of the triangle is A = ( 1/2 ) x Length x Base ( sin 72° )

The difference of two complementary angles is 70 degrees. Find the measures of the angles.
Answer:
[tex]80[/tex]° and [tex]10[/tex]°
Step-by-step explanation:
Complementary angles are a pair of angles whose measures have a sum of [tex]90[/tex]°. Therefore, if we let the measure of the bigger angle be [tex]x[/tex], then the measure of the smaller angle will be [tex]x-70[/tex] because we are given that the difference of the measures of the two angles is [tex]70[/tex]°. We can write the following equation to solve for [tex]x[/tex]:
[tex]x+x-70=90[/tex]
Solving for [tex]x[/tex], we get:
[tex]x+x-70=90[/tex]
[tex]2x-70=90[/tex] (Simplify LHS)
[tex]2x-70+70=90+70[/tex] (Add [tex]70[/tex] to both sides of the equation to isolate [tex]x[/tex])
[tex]2x=160[/tex] (Simplify)
[tex]\frac{2x}{2}=\frac{160}{2}[/tex] (Divide both sides of the equation by [tex]2[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=80[/tex] (Simplify)
Therefore, the measure of one angle is [tex]80[/tex]° and the measure of the other angle is [tex]x-70=80-70=10[/tex]°. Hope this helps!
We know, sum of complementary angles = 90°
Let, one of the angle = x°
∴ Another angle = (90 - x)°
As per condition,
(x°) - (90 - x)° = 70°
⇒ x° - 90° + x° = 70°
⇒ 2x° = 70° + 90° = 160°
⇒ x° = 80°.
So, angles are:-
x° = 80° (90 - x)° = (90 - 80)° = 10°.In a basket of apples 12% of them are rotten. If there are 66 rotten apples how many total apples are there?

A two-pound mixture of raisins and peanuts costs $7.50. The raisins cost $3.25 a pound and the peanuts costs $5.75 a pound. How much does each ingredient weight in the mixture?
he mixture refers to the one pound mix of peanuts and raisins that cost $7.50.
So you need to figure out how much of that 1 lb is raisins and how much is peanuts based on how much they each cost separately.
r=raisins, p=peanuts
(r x $3.25) + (p x $5.75) = $7.50
The weight of the ingredients in the mixture are 1.8 pound and 0.2 pound respectively.
What is a system of linear equations?A system of linear equations is a group of equations having same number of variables and degree.
For the n number of variables n number of equations are required.
On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.
The given problem can be solved as follows,
Suppose the amount of raisins be x pound,
And, the amount of peanuts be y pound,
Now, the equation for the total amount is given as,
x + y = 2 (1)
And, for the cost as,
3.25x + 5.75y = 7.50 (2)
Multiply equation (1) by 3.25 and then subtract from (2) as follows,
3.25(x + y) - (3.25x + 5.75y) = 2 × 3.5 - 7.50
=> -2.5y = -0.5
=> y = 0.2
Then, x + 0.2 = 2
=> x = 1.8
Hence, the weight of raisins and peanuts in the mixture is given as 1.8 pound and 0.2 pound respectively.

A boy is twice as tall as his little sister and 30cm shorter than his father. Their combined height is 3.8 meters. Find (in cm) the height of each person.
Answer:
Call the sister's height x. The boy is twice as tall, so that's 2x. The father is 30 cm taller than the boy, so his height is 2x + 30. The combined height is 3.8m, which is 380cm. Now you can write an equation
x + 2x + 2x + 30 = 380
collect like terms
5x = 350
x = 70
the sister is 70cm tall, the boy is 2*70 = 140 cm, and the father is 140 + 30 = 170cm
Check that the heights add up to 3.8m: 70 + 140 + 170 = 380 cm = 3.8m. Correct

In a stationery design, the number of ovals is proportional to the number
of squares. How many squares will there be when there are 75 ovals?
Question Help
When there are 75 ovals, how many squares are there?
Answer:
75 ÷k number of squares based on the k value
Step-by-step explanation:
Let us suppose the ovals number be x
And, the square number be y
Now in the case when the ovals number is proportional to the square number
So, it would be defined as
x∝y
And,
x = ky
Here k is the constant
Now
If there are 75 ovals,
So, x = 75
Now put this in the above equation
75 = kx
x = 75 ÷k

At the start of the diet keirin weighted 14 stone 13 pounds three months later he weighted 13 stone 10 pounds there are 14 pounds in a stone.
Answer:
The amount of weight he has lost in 3 months is 1.215 stone or 1 stone 3 pounds
Step-by-step explanation:
From the above question, we are to calculate the amount of weight he has lost in three months
1 stone = 14 pounds
Let's convert all the weight lost to stone
At the start of the diet keirin weighted 14 stone 13 pounds
14 pounds = 1 stone
13 pounds = x
Cross Multiply
14x = 13
x = 13/14
x = 0.9285714286 stone
Approximately = 0.929 stone
Hence:
14 stone 13 pounds = 14 + 0.929 = 14.929 stone
Three months later he weighted 13 stone 10 pounds
14 pounds = 1 stone
10pounds = x
Cross Multiply
14x = 10
x = 10/14
x = 0.7142857143 stone
Approximately = 0.714 stone
Hence:
13 stone 10 pounds = 13 + 0.714 = 13.714 stone
The amount of weight he has lost is calculated as:
14.929 stone - 13.714 stone = 1.215 stone or 1 stone 3 pounds
