Alina has to spend $30 000 on expenses each year. If that amount of money is 40% of her total yearly earnings, then how much money does Alina make per year?
Answer:
$75000
Step-by-step explanation:
Given data
Let her yearly earnings be x
so
40% of x= $30000
40/100*x=30000
0.4x=30000
x=30000/0.4
=$75000
Hence the total amount made per years is
$75000

Answer:
F - 20 songs
Step-by-step explanation:
Sandra has $120. Each gift card costs $12.
$120 ÷ $12 = 10. So, Sandra buys 10 gift cards.
Each gift card can be used to download 10 songs. So, 10 gift cards can be used to download 10 × 10 = 100 songs.
There are 5 children. Each child can download 100 ÷ 5 = 20 songs.

Answer:
256 miles
Step-by-step explanation:
The Pythagoras theorem is a² = b² + c² where a is the hypotenuse or longest side
To find the shorter side, the equation is rearranged so c² = a² - b² (whether it is b or c doesn't matter)
so √377² - 277² = 255.7342371
Answer to number 22
Answer: 256 miles
A cube has a surface area of 6. What's the volume?
a 1
b 1/6
c 6
d 3/2
Answer:
Well all sides of a cube are congurent or equal and since the surface area is 6. We can develop a formula to find the missing variables.
Well since the surface area of a cube can be found by using 6a^2 where a is the side lengths.
So since 6a^2=6
Solve
a^2=1
a=1
SO each side is equivalent to 1
Now to find the volume just do LWH and you should get 1 as your answer or in this case (A)
Answer:
V = 1
Step-by-step explanation:
A=6a2
V=a3
Solving for V
V=6A3/2
36=6·63/2
36÷6 = 1
V = 1

Answer:
3) x = −11
4) x = 40/11 or 3.636363... (it keeps going)
5)
Step-by-step explanation:
3) 5x/6 − ( 2x − 1/2 ) + 4 − 2x/3 = 11
Step 1: Simplify both sides of the equation.
5x/6 − ( 2x−1/2 ) + 4 − 2x/3 = 11
5x/6 + − x + 1/2 + − 2/3x + 4/3 = 11 ( Distribute )
5/6x + − x + 1/2 + − 2/3x + 4/3 = 11
( 5/6x + − x + − 2/3x ) + ( 1/2 + 4/3 ) = 11 ( Combine Like Terms )
−5/6x + 11/6 = 11
Step 2: Subtract 11/6 from both sides.
−5/6x + 11/6 − 11/6 = 11 − 11/6
−5/6x = 55/6
Step 3: Multiply both sides by 6/(-5).
( 6/−5 ) * ( −5/6x ) = ( 6/−5 ) * ( 55/6 )
x = −11
4) 10 - 2x = 3/4x
x = 40/11
(going to also be long I so wont put my work here)
5) -3( x - 3 ) - 9x - 9 = 4( x + 2 ) - 12
x = 1/4
(again, is long so wont put work)

can someone help to find the missing angle measurements
Answer:
Angle 1 = 75°
Angle 2 = 55°
Angle 3 = 55°
Angle 4 = 40°
Angle 5 = 140°
Angle 6 = 40°
Angle 7 = 75°
Angle 8 = 65°
Angle 9 = 115°
Step-by-step explanation:
1) We start with angle 2
Angle 2
Angles on a straight line = 180°
Hence,
b + 125° = 180°
b = 180° - 125°
b = 55°
Angle 2 = 55°
2)Angle 1
The sum of angles in a triangle = 180°
Hence
Let Angle 1 = a
50° + 55° + a = 180°
a = 180° - (50° + 55°)
a = 180° - 105°
a = 75°
3)Angle 3
Angle 2 and Angle 3 are vertical angles
So we use the Vertical angle theorem
This means
Angle 2 = Angle 3
Angle 2 = 55°
Hence, Angle 3 = 55°
4) Angle 4
Sum of Angles in a triangle = 180°
Let Angle 4 = d
Hence:
85° + Angle 3 + d = 180°
85° + 55° + d = 180°
d= 180° - (85° + 55°)
d = 180°- 140°
d = 40°
5)Angle 5
Angle 4 and Angle 5 are angles on a straight line
Sum of angles on a straight line = 180°
Angle 4 = 40°
Let Angle 5 = e
Hence:
40° + e = 180°
Collect like terms
e = 180° - 40°
e = 140°
6) Angle 6
Angle 4 and Angle 6 are vertical angles
Using Vertical angle theorem,
Angle 4 = Angle 6
Angle 4 = 40°
Hence, Angle 6 = 40°
7)Angle 9
Solving for Angle 9,
Sum of angles on a straight line = 180°
Angle 9 = i
i + 65° = 180°
i = 180° - 65°
i = 115°
8) Angle 8
= Angle 9 and Angle 8 are angles in a straight line
= Angle 8 = h
h + 115° = 180°
h = 180° - 115°
h = 65°
9)Angle 7
Sum of angles in a triangle = 180°
Angle 7 = g
g = 180° - (65° + Angle 6)
= 180° - (65 + 40
= 180° - 105°
= 75°
Van a poner balfosas en una calle que mide 3 hm y 9 dam de largo. Ya han embaldosado 125 m de calle ¿A cuantos metros les falta poner baldosas
Answer:
Faltan 265 metros por embaldosar.
Step-by-step explanation:
Un decámetro equivale a 10 metros, mientras que un hectómetro equivale a 100 metros. A continuación, calculamos la longitud equivalente de calle en metros:
[tex]x = 3\,hm \times \left(\frac{100\,m}{1\,hm} \right)+9\,dam\times \left(\frac{10\,m}{1\,dam} \right)[/tex]
[tex]x = 390\,m[/tex]
La longitud pendiente por poner baldosas es la longitud total menos la longitud ya embaldosada, es decir:
[tex]y = 390\,m-125\,m[/tex]
[tex]y = 265\,m[/tex]
Faltan 265 metros por embaldosar.

Step-by-step explanation:
Anthony has 400 marbles. He sells 1/4 of the marbles to Jayveon, he gives 10% to Abdul and donates 10 marbles to his little brother's collection. Explain in writing (typing) how to find the number of marbles each person received then explain how to find the number of marbles Anthony has left. (Remember to write 5 or more complete sentences.)
help me please
Answer: See explanation
Step-by-step explanation:
Number of marbles = 400
Anthony sells 1/4 of the marbles to Jayveon. This will be:
= 1/4 × 400
= 100 marbles
Anthony gives 10% to Abdul. Abdul will have:
= 10% × 400
= 0.1 × 400
= 40 marbles
He gave 10 marbles to his little brother.
The number of marbles that Anthony has left will be:
= 400 - (100 + 40 + 10)
= 400 - 150
= 250 marbles
pleaseeee explain !!!
A is the answer because if we want the unit rate we do
2/3÷2/3 and 15 1/5, we can turn 15 1/5 into a improper fraction first so 76/5 and we do 76/5 ÷2/3 which is equal to
76/5×3/2=114/5
114/5 simplifies into 24 4/5.
so Naomi can travel 24 4/5 gal per mile.
Hope this helps!
