Recall that two angles are complementary if the sum of their measures is 90°. Find the measures of two complementary angles if one angle is 6º more than three times the other angle.
Answer:
The two angles are 69° and 21°.
Step-by-step explanation:
Write out the expression:
let x and y be two angles that are complementary and the sum of their measures is 90°
-> x° + y° = 90°
if one angle is 6º more than three times the other angle:
-> x° = 6° +3y°
Plug x = 6+3y into x° + y° = 90°
6° + 3y° + y° = 90°
Solve for y
4y° = 84°
y° = 21°
Plug y into x° + y° = 90°
x° + 21° = 90°
Solve for x°
x° = 90° - 21° = 69°

Olivia does chores every Saturday morning. She spends of her time cleaning her room. Of the remaining of her time, she spends of it cleaning the kitchen. How much of Olivia's total time does she spend cleaning the kitchen?
Answer:
4/7 of her total time cleaning the kitchen
Step-by-step explanation:
Olivia does chores every Saturday morning. She spends 1/3 of her time cleaning her room. Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen. How much of Olivia's total time does she spend cleaning the kitchen?]
Let
x = her total time
Room cleaning = 1/3x
Time remaining = 2/3x
Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen.
Kitchen cleaning = 6/7 of 2/3x
= 6/7 * 2/3x
= (6*2)x/(7*3)
= 12/21x
= 4/7x
Olivia spent 4/7 of her total time cleaning the kitchen
Which of the following is not one of Euclid’s postulates?
1.) A circle may be described with any given point as its center and any distance as its radius.
2.) All right angles are congruent.
3.) All complementary angles form a right angle.
4.) A straight line may be drawn from any given point to any other.
Answer:
3.) All complementary angles form a right angle.
hope this helps you :)
"All complementary angles form a right angle" is not Euclid's postulates. Therefore, option C is the correct answer.
We need to identify which of the given option is not one of Euclid’s postulates.
What are Euclid’s postulates?A statement, also known as an axiom, is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived. The whole of Euclidean geometry, for example, is based on five postulates known as Euclid's postulates.
Postulate 1: A straight line may be drawn from any one point to any other point.
Postulate 2:A terminated line can be produced indefinitely.
Postulate 3: A circle can be drawn with any centre and any radius. Postulate 4: All right angles are equal to one another.
From the about options we can draw a conclusion that "All complementary angles form a right angle" is not Euclid's postulates.
Therefore, option C is the correct answer.

A strange bowling bow is made up of plastic and wood. The weight of the two materials are in a ratio of 5 to 9 if the bowling ball weights 238 ounces what is the weight of the plastic.
Answer:
85 ounces
Step-by-step explanation:
A strange bowling bow is made up of plastic and wood. The weight of the two materials are in a ratio of 5 to 9 if the bowling ball weights 238 ounces what is the weight of the plastic.
We are given the ratio:
Plastic : wood
5:9
Sum of proportion = 5 + 9 = 14
The weight of the bowling ball = 238 ounces
Hence
The weight of the plastic is calculated as:
5/14 × 238 ounces
= 85 ounces

Answer :[tex] \large \underline{\boxed{\bf{x = 2}}}[/tex][tex] \large \underline{\boxed{\bf{y = 3}}}[/tex]⠀ ⠀⠀
Explanation :⠀ ⠀⠀
Given :y = 5x - 7⠀ ⠀⠀ ⠀ ⠀⠀ - (i)- 3x - 2y = - 12⠀ ⠀⠀ ⠀- (ii)⠀ ⠀⠀
From equation (i), we have :
[tex] \tt : \implies y = 5x - 7[/tex]
⠀ ⠀⠀
By Substituting y = 5x - 7 in equation (ii), we get :
[tex] \tt : \implies - 3x - 2(5x - 7) = - 12[/tex]
[tex] \tt : \implies - 3x - 10x + 14 = - 12[/tex]
[tex] \tt : \implies - 13x = - 12 - 14[/tex]
[tex] \tt : \implies - 13x = - 26[/tex]
[tex] \tt : \implies 13x = 26[/tex]
[tex] \tt : \implies x = \dfrac{26}{13}[/tex]
[tex] \tt : \implies x = 2[/tex]
[tex] \large \underline{\boxed{\bf{x = 2}}}[/tex]
⠀ ⠀⠀
Now, By substituting x = 2 in equation (i), we get :
[tex] \tt : \implies y = 5(2) - 7[/tex]
[tex] \tt : \implies y = 10 - 7[/tex]
[tex] \tt : \implies y = 3[/tex]

Hence, solution of given system of equations are :

I need help can someone help me please????
Answer:
on the bottom equation you can subtract 1 from both sides, x = 2y+1 so you substitute that in for x on the other equation, 7(2y+1) - 2y = 1 or 14y + 7 -2y = 1 then 12y = -6 y = -1/2 which you put back into the other equation, 2(-1/2) = x -1 so -1 = x - 1 then x = 0, the answer is (0, -1/2)

9514 1404 393
Answer:
97.42 square units
Step-by-step explanation:
The area of a sector is given by ...
A = (1/2)r²θ
where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.
75° = (75°)×(π/180°) radians = (5/12)π radians
Then the area is ...
A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units
__
Equivalently, you can find the area of the circle in the usual way:
A = πr² = π(12.2²) ≈ 467.59465
Then, multiply by the fraction of the circle that is shaded (75°/360°)
sector area = (467.59465)(75/360) = 94.42 . . . square units

The mens taxable is income is rs 14280 the state tex instruction tel him to pay 2%on the first rs3000 of his taxable incom 3% on each of the second and third rs 3000 and 4% o the remainder what is the total amount of income tax that he must pay
Answer:
Rs. 451.2
Step-by-step explanation:
It is given that a men's total taxable income is Rs. 14,280.
He is charged by the state tax for 2% on the first Rs. 3000.
i.e. [tex]$2 \% \times 3000$[/tex]
[tex]$=\frac{2}{100} \times 3000$[/tex]
= Rs. 60
Then he is asked to pay 3% on the second Rs. 3000
i.e. [tex]$3 \% \times 3000$[/tex]
[tex]$=\frac{3}{100} \times 3000$[/tex]
= Rs. 90
Similarly, he pays 3% on the third Rs. 3000
i.e. [tex]$3 \% \times 3000$[/tex]
[tex]$=\frac{3}{100} \times 3000$[/tex]
= Rs. 90
Lastly, he pays 4% on the remaining amount. i.e 14,280 - (3000+3000+3000) = 14,280 - 9000 = Rs. 5280
∴[tex]$4 \% \times 5280 $[/tex]
[tex]$=\frac{4}{100} \times 5280$[/tex]
= Rs. 211.2
Thus the total amount of the income tax the man has to pay is
= 60+90+90+211.2
= Rs. 451.2

Find the perimeter of the triangle whose vertices are the following specified points in the plane.
(5,6), (4,1) and (-4,2)
Answer:
23 units
Step-by-step explanation:
Let the vertices of the triangle be A(5,6), B(4,1) and C(-4,2)
Perimeter of the triangle = AB + AC + BC
AB = √(5-4)²+(6-1)²
AB = √1²+5²
AB = √1+25
AB = √26
For BC where B(4,1) and C(-4,2)
BC = √(4-+4)²+(1-2)²
BC = √8²+1²
BC = √64+1
BC = √65
For AC where A(5,6) and C(-4,2)
AC = √(5+4)²+(6-2)²
AC = √9²+4²
AC = √81+16
AC = √97
Perimeter = √97 + √26 + √65
Perimeter = 9.85+5.09+8.06
Perimeter = 23
Hence the perimeter of the triangle is approx 23 units

-4x+35>2
Answer:
I don't know........................
Answer:
x < 33/4
Step-by-step explanation:
1.) -4x+35 > 2 (Move the constant to the right-hand scale side and change its sign)
-4x > 2 - 35
2.) -4x > 2 - 35 (Calculate the difference)
4x > -33
3.) -4x > -33 (Divide both sides of the inequality by -4 and flip the inequality sign)
x < 33/4

Answer:
Step-by-step explanation:
3. 10x + 6 = 8x
8x = 10x + 6
-2x = 6
x = -3
4. y = 8(1) - 5= 8 - 5 = 3
y = 8(2) - 5 = 16 - 5 = 11
y = 8(5) - 5 = 40 - 5 = 35
y = 8(0) - 5 = 0 - 5 = -5
y = 8(-1) - 5 = -8 - 5 = -13
[tex]10x + 6 = 8x[/tex]
[tex]6 = 8x - 10x[/tex]
[tex]6 = - 2x[/tex]
[tex]6 \div - 2 = x[/tex]
[tex] - 3 = x[/tex]
Number 4 :[tex]y = 8x - 5[/tex]
When [tex] x = 1, y = \bold{ 3} [/tex]
[tex]y = (8 \times 1)- 5[/tex]
[tex]y = 8 - 5[/tex]
[tex]y = 3[/tex]
When [tex] x = 2, y = \bold{ 11} [/tex]
[tex]y = (8 \times 2)- 5[/tex]
[tex]y = 16 - 5[/tex]
[tex]y = 11[/tex]
When [tex] x = 5, y = \bold{35} [/tex]
[tex]y = (8 \times 5)- 5[/tex]
[tex]y = 40 - 5[/tex]
[tex]y = 35[/tex]
When [tex] x = 0, y = \bold{-5} [/tex]
[tex]y = (8 \times 0)- 5[/tex]
[tex]y = 0 - 5[/tex]
[tex]y = - 5[/tex]
When [tex] x = -1, y = \bold{-13} [/tex]
[tex]y = (8 \times - 1)- 5[/tex]
[tex]y = - 8 - 5[/tex]
[tex]y = - 13[/tex]

Can anybody help me with this please
Jan is not correct. The opposite of any number will not always be a positive. This is because the opposite of a positive number is negative and the opposite of a negative number is positive.
Basically, opposite numbers are numbers that are the same distance to 0 on a number line. If we were to have a positive 1, the opposite of that number would be a -1, because that's equally distant from 0 on a number line.
