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°.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
Step-by-step explanation:

The area of the triangle is A = 61.8 units²
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° )
A = 1/2 ( 10 ) ( 13 ) sin 72°
A = 61.8 units²
Hence , the area is A = 61.8 units²

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

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.
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

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°)

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.
