Sarah answered 5% of the questions on a test incorrectly. If she answered 3 questions incorrectly, how many questions were on the test?

Answer:

[tex]c \div \frac{1}{2}y = x \\[/tex]

y = 1

Step-by-step explanation:

600,000 ÷ 1/2 = 300,000

c = 600,000

y = 1/2

x = 300,000

Answer:

600000(.5)^y

Step-by-step explanation:

Answer:

Step-by-step explanation:

Area is the product of two dimensions.

If each dimension is doubled, then the area becomes 2*2 = 4 times greater.

If each face is 4 times greater, then their sum will be 4 times greater.

The sum of the faces is the total surface area, therefore the B's surface area is 4 times as great as A's surface area.

Answer:

Step-by-step explanation:

Diagonal = 8√2

x= 30.....................

Answer:

x=30

Step-by-step explanation:

how:

so your equation right now is 2x+40=100, so figure this equation out you have to do the opposite so it will be

100-40=60

60/2=30

which makes x=30

hope that helps

please mark as brainliest if correct

thank you

Answer:

x=28

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x+5+x−5=56

x+5+x+−5=56

(x+x)+(5+−5)=56(Combine Like Terms)

2x=56

2x=56

Step 2: Divide both sides by 2.

2x/2=56/2

x=28

Answer:

1836

Formula: P(1+r)^t

Steps- 1800$( 1 + .02)^10

instead of doing 2% we move the decimal two places to the left and get .02

From here you can just add it and get 1836$

I noticed you didn't put the annual interest rate, so I assumed it would be annually.

Answer:

0.12 or 12%

Step-by-step explanation:

I=Prt

r= I/(Pt)

r = 160/(2000 x 8/12)

r = 160/(4000/3)

r = 3/25

r = 0.12

Answer:

Los primeros 2 días que el camión visita ambas calles el mismo día es el 15 y 30 de diciembre.

Step-by-step explanation:

Los múltiplos de un número son todos los posibles resultados de multiplicar ese número por todos y cada uno de los números naturales.

Es decir, los múltiplos de un número natural son los números naturales que resultan de multiplicar ese número por otros números naturales.

El conjunto de los múltiplos de un número determinado (salvo el cero) es infinito, pues existen infinitos naturales para multiplicar.

Para determinar cuáles son los primeros 2 días que el camión visita ambas calles el mismo día, debes encontrar los múltiplos de 3 y 5:

múltiplos de 3: 3; 6; 9; 12; 15; 18; 21; 24; 27; 30

múltiplos de 5: 5; 10; 15; 20; 25; 30; 35; 40; 45; 50

Podes observar que los 2 primeros números comunes o que coinciden entre los múltiplos de 3 y 5 son 15 y 30. Esto quiere decir que los primeros 2 días que el camión visita ambas calles el mismo día es el 15 y 30 de diciembre.

Answer: It is B)

Answer:

you have not gave full question what is f (x) given in question.

The First equation and the Third Equation

are equivalent to 6x - 24.

1) 6 ( x - 4 )

3)3 ( 2x - 8 )

Answer:

first one and third one. hope u get it right!

Step-by-step explanation:

6(x-4)

distribute (6*x and 6*4) then it equals 6x - 24

2(3x - 24) = 6x - 48

3(2x - 8) = 6x - 24

3(3x - 21) = 9x - 63

Answer:

Scale Factor is 8/9 or 9/8

x= 13.5

y=8

z= 128

Step-by-step explanation:

Since MP = NO then WZ= XY  XY=8 so WZ= 8 =(y)

<z = <NOP  z= 128

XY = 8 and MP = 9  ratio between the corresponding parts is 8/9

[tex]\frac{8}{9} = \frac{12}{x} \\108= 8x\\13.5 = x[/tex]

Answer:

Step-by-step explanation:

base length b = 32 cm

slant height L = 30 cm

height h = √(L²-(½b)²)

= √(30²-0.25·32²)

≅ 25.3771550809 cm

volume V = (⅓)b²h

= (⅓)32²·25.38

≅ 8662.07 cm³

Answer:

x = 3

Step-by-step explanation:

Use distributive property: a(b +c) =(a*b) + (a*c)

3(x + 6) = 27

3*x + 3*6 = 27

3x + 18  = 27 {Subtract 18 from both sides}

3x + 18 -18 = 27 - 18

         3x    = 9  {Divide both sides by 3}

        3x/3 = 9/3

x = 3

Answer:

its fine because

Step-by-step explanation:

People who grew up with it often find it to be fine, good, or even delightful. Others may find it to be absolutely disgusting. Personally, I think SPAM tastes fine, but it's a bit too salty on its own. So, I think it's best when eaten with other foods that need some extra salt (like rice, eggs, etc.).

Answer:

Answer:

.0024

Step-by-step explanation:

Hey There!

So when converting a percentage to a decimal all we have to do is move the decimal place over to the left 2 times

so it would be .0024

hope this helps ~ MarkAnswers

Answer:

0.0024

Step-by-step explanation:

0.24% = 0.0024 in decimal form. Percent means 'per 100'. So, 0.24% means 0.24 per 100 or simply 0.24/100.

Answer:

ok thx for my points back

Step-by-step explanation:

Rewrite the fractions so they have a common denominator

3/4 = 15/20

Now add:

4 15/20 + 7 11/20 = 11 26/20

26/20 simplifies to 1 3/10

11 + 1 3/10 = 12 3/10 total minutes

Answer:

4x+36

Step-by-step explanation:

All you have to do is multiply the 4 by the numbers inside the parentheses.

4 times x is 4x

4 times 9 is 36

You can't find the answer since you don't know what x is.

I hope this helps, and have a great day! :)
