C)n + 8 = 42
D) 8n = 42
E) n = 5

Responda:

3,91 m

Explicação passo a passo:

Dado o seguinte:

Comprimento da escada = 4,3 m

Distância da base da parede = 1,8m

Altura da parede =?

O problema pode ser resolvido usando Pitágoras:

hipoteno = sqrt (oposto² + adjacente ²)

Hipoteno = comprimento da escada = 4,3

4,3 = sqrt (1,8² + altura²)

Quadrar ambos os lados

4,3² = 1,8² + altura²

4,3² - 1,8² = altura²

18,49 - 3,24 = altura²

15. 25 = altura²

Tire a raiz quadrada de ambos os lados

Sqrt (15,25) = altura

Altura = 3,905

Altura = 3,91 m

Answer:

  126

Step-by-step explanation:

The least common multiple of 7, 9, and 6 is the product of the unique factors.

  7 = prime

  9 = 3^2

  6 = 3·2

The LCM is 7·3^2·2 = 126

Step-by-step explanation:

The question is incomplete. Here is the complete question:

The cost saver grocery club sells sheet cakes. Each 1/4 sheet of cake requires 0.75 teaspoon of baking soda. Which expression can be used to find the amount of baking soda needed for a whole cake? Select all the expressions that apply.

Let the amount baking soda required for a whole cake be y.

If each 1/4 sheet of cake requires 0.75 teaspoon of baking soda, the expression that can be used to find the amount of baking soda needed for a whole is as shown below;

1/4 sheet of cake = 0.75 teaspoon of soda

1 sheet of cake = y teaspoon of soda

cross multiply

1/4 * y = 1 * 0.75

y/4 = 0.75

multiply both sides by 4

y/4 * 4 = 0.75 * 4

y = 4(0.75)

y =  3 teaspoon of baking soda

Step-by-step explanation:

Answer:

the right answer is 56.25

Answer:

48 days

Step-by-step explanation:

Let us assume the following things

Work done by 1 man in 1 day is [tex]\frac{1}{x}[/tex]

Work done by 1 woman in 1 day is [tex]\frac{1}{y}[/tex]

It is mentioned that

six men + ten women finished in 8 days

So,

[tex]\frac{6}{x} + \frac{10}{y} = \frac{1}{8}[/tex] .............. (1)

And,

four men + six women finished in 12 days

[tex]\frac{4}{x} + \frac{6}{y} = \frac{1}{12}[/tex] ...............(2)

Now solve these two equations

And we assume [tex]\frac{1}{x}[/tex] be u and [tex]\frac{1}{y}[/tex] be v

So

Now the equation is

[tex]6u\ + 10v\ = \frac{1}{8} \\\\\4u\ + 6v\ = \frac{1}{12}[/tex]

So,

u = 1 ÷ 48 , v = 0

Therefore x = 48

So the time taken for finish the work is 48 days

Answer:

∠64° and ∠26°

Step-by-step explanation:

Complementary angles add up to 90° total (two angles).

Lets give variable values to each angle:

x= 12 more than twice the measure of the complement

y= complement

Write an equation equaling to a total of 90:

[tex]x+y=90[/tex]

Write an algebraic expression for the value of x:

[tex]12+2y[/tex]

Insert the value for x into the equation:

[tex]12+2y+y=90[/tex]

Simplify and solve for y:

[tex]12+3y=90\\\\12-12+3y=90-12\\\\3y=78\\\\\frac{3y}{3}=\frac{78}{3}\\\\ y=26[/tex]

The value of y is 26. Insert this value into the original equation and solve for x:

[tex]x+26=90\\\\x+26-26=90-26\\\\x=64[/tex]

The value of x is 64. So, the complemenatry angles are 64° and 26°.

:Done

From the given measure whose angle is  12° more than twice the measure of its complement.

The measure of the two angles is 64° and 26° respectively.

Complementary angles are angles whose sum is equal to 90°. It is usually composed of two angles complementing themselves. Hence, the term complementary angles.

Mathematically;

∴

p + q = 90°    ( complemntary angles)

If one of the angles is 12 more than twice its complement;

i.e.

Let p = 12

SO, the algebraic equation for the value of p is:

12 + 2q = 90

Replacing the value of q to solve the equation, we have:

12 + 2q + q = 90

12 + 3q = 90

3q = 90 - 12

3q = 78

q = 78/3

q = 26°

From p + q = 90°    ( complemntary angles)

Replacing the value of q = 26°, we have:

p + 26° = 90°

p = 90° - 26°

p = 64°

In conclusion, the measure of each angle is 64° and 26°.

To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one.

Step-by-step explanation:

We can convert this word problem into an equation by examining what it  says.

6 times a number

Since we don't know the value of that number, we can represent it as [tex]x[/tex]. 6 times [tex]x[/tex] will be [tex]6x[/tex]

Greater than has this symbol: [tex]>[/tex]

3 less than 4 times a number. We can break this down. 4 times a number is [tex]4x[/tex]. 3 less than that will be [tex]4x-3[/tex].

Combining that all, we get [tex]6x > 4x-3[/tex]

Step-by-step explanation:

x + y = 5

12x + 9y = 51

x = 5 - y

12(5 - y) + 9y = 51

60 - 12y + 9y = 51

-3y + 60 = 51

-3y = 51 - 60

-3y = -9

y = -9/-3

y = 3

x = 5 - y

x = 5 - 3
