What is the value of x?

Mathematics
1 answer:
Alecsey [184]2 years ago
6 0

Answer: x = 8

Step-by-step explanation:

Using The Pythagorean theorem (a^2 + b^2 = c^2) we can find A or In This Case X

Plug In The Numbers:

x^2 + 6^2 = 10^2

simplify

x^2 + 36 = 100

Next, Since Were Trying To Find X And Not C, We Subtract B From C Or 36 From 100

x^2 + 36 - 36 = 100 - 36

simplify

x^2  = 64

Next, To Get Rid Of The Square, Were Going To Find The Square Root Of Both Sides Of The Equation

sqr/a = sqr/64

simplify

x = 8

How to solve this question. I need to show my work for this question.
IrinaK [193]

Step-by-step explanation:

Recall that 1 dozen = 12 so 4 dozen cookies has a total of 48 cookies. We are going to use the following ratios to solve the problem:

\left(\dfrac{3\:\text{eggs}}{48\:\text{cookies}}\right) and \left(\dfrac{48\:\text{cookies}}{3\:\text{eggs}}\right)

a) 12\:\text{eggs}×\left(\dfrac{48\:\text{cookies}}{3\:\text{eggs}}\right) = 192\:\text{cookies}

b) 18 dozen cookies = 216 cookies

216\:\text{cookies}×\left(\dfrac{3\:\text{eggs}}{48\:\text{cookies}}\right) = 13.5\:\text{eggs}

What is $6.25 marked up 25%
Marta_Voda [28]

Answer:

$6.25 marked up 25% is $7.81

Step-by-step explanation:

First, you have to find what 25% is of 6.25.

Step 1: Our output value is 25.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 25=100%.

Step 4: Similarly, x=6.25%.

Step 5: This results in a pair of simple equations:

25=100%(1)

x=6.25%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

<u>25 </u> =   <u>100</u>

 x       6.25

Step 7: Again, the reciprocal of both sides gives

<u> x </u> =  <u>6.25</u>

25     100

x= 1.5625

x≈ 1.56

Once you've known what 25% is, you add it to 6.25.

1.56+6.25= 7.81
