70 is what percent of 56
Answer:
70 is 125% of 50
Step-by-step explanation:
I hope this helped :)
The percentage value of 70 to 56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.
Given that, to find what percent of 70 in 56.
To find out if the percentage of 70 is 56, follow the steps:
Step 1:Find the ratio of the two numbers that is the ratio of 70 and 56 gives:
[tex]70:56 = 70/56[/tex]
Divide both numerator and denominator by 14 yields in:
[tex]= 5/4[/tex]
Step 2: Convert the result of step 1 into decimals by a long division of 5 by 4.
[tex]5/4 = 1.25[/tex]
Step 3: Find the percentage value of the decimal by multiplying the decimal by 100.
[tex]1.25 \times100 = 125[/tex]%
Therefore, the percentage value of 70 to 56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.

Ava makes bead necklaces. She has a total of write the value of each expression.of 6,048 beads. Each necklace has 24 beads.Her friend Maria says that the greatest number of necklaces she can make with the beads is 162. Maria’s work is shown here.Explain why Maria’s answer is incorrect and how she can find the correct answer.
Answer:
She made the 6 into a five to make the 0 a 1 too early, because 24 can go into 60 twice, but in order to subtract the 8, you would then have to make the 6 into a 5 as well as the 0 into a 1.
Step-by-step explanation:
6048 divided by 24 is 252
The first month a company was open, it had 2 employees. At the end of 6 months, the company had 10 employees. If the number of employees increases at a steady rate, write an equation that illustrates this situation.
the equation would be 2[6]+10 however if we were to solve it would have been 2(6)+10 = 22 employees
The equation y = 4/3 x + 2 represents the number of employees, increases at a steady rate.
Where x shows the number of months
What is an equation ?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
At staring, when the company was opened,
The number of employees = 2.
After 6 months the number of employees in company = 10.
The increased number of employees = 10 - 2 = 8
In 6 months 8 employees are increases.
In 12 months number of employees = 10 + 8 = 18
Let y represents the number of employees
And x represents the number of months
So the equation can be written as,
y = 4/3 x + 2
The required equation is y = 4/3 x + 2.

if
[tex]a = \frac{2x + \sqrt{x} }{x} [/tex]
and
[tex]b = \frac{1 - 2 \sqrt{x} }{ \sqrt{x} } [/tex]
without sing a calculator, show that
[tex](a + b) {}^{2} = \frac{4}{x} [/tex]
Answer:
Step-by-step explanation:
Rationalize the denominator of b. So, multiply the numerator and denominator by [tex]\sqrt{x}[/tex]
[tex]b = \frac{(1-2\sqrt{x}) *\sqrt{x}}{\sqrt{x}*\sqrt{x} }=\frac{1*\sqrt{x} -2\sqrt{x} *\sqrt{x} }{\sqrt{x} *\sqrt{x} }\\\\=\frac{\sqrt{x} -2x}{x}\\[/tex]
Now, find a +b
[tex]a +b = \frac{2x+\sqrt{x} }{x}+\frac{\sqrt{x} -2x}{x}\\\\=\frac{2x+\sqrt{x} +\sqrt{x} -2x}{x}[/tex]
Combine like terms
[tex]= \frac{2x-2x+\sqrt{x} +\sqrt{x} }{x}\\\\=\frac{2\sqrt{x} }{x}[/tex]
Now find (a + b)²
(a +b)² = [tex](\frac{2\sqrt{x} }{x})^{2}[/tex]
[tex]= \frac{2^{2}*(\sqrt{x} )^{2}}{x^{2}}\\\\= \frac{4* x}{x^{2}}\\\\= \frac{4}{x}[/tex]
Hint: [tex]\sqrt{x} *\sqrt{x} =\sqrt{x*x}=x[/tex]

Please help me on this, I need to find X!
Answer:
x would most likely be 55.
Explanation:
because it is a right angle which is = to 90.
90-35=55
Answer:
55°
Step-by-step explanation:
Right angles are 90°
90 - 35 = 55° (x°)
The angles are adjacent, if it was vertical both angles would have the same degree. Adjacent angles are angles which have a common vertex and occur in right angled triangles.
