Find the number if:
5/9 of it is 90.
And another similar question;
Find the number if:
7/3 of it is 5 5/6
I need help with both of these questions.
Answers
Answer:
162 and [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
To find the original number multiply by the reciprocal of the multiplier, that is
90 × [tex]\frac{9}{5}[/tex] = [tex]\frac{810}{5}[/tex] = 162
------------------------------------------------------------------------
Similarly
Change the mixed number into an improper fraction
5 [tex]\frac{5}{6}[/tex] = [tex]\frac{35}{6}[/tex] , then
[tex]\frac{35}{6}[/tex] × [tex]\frac{3}{7}[/tex] ( cancel 35 and 7 by 7 / cancel 6 and 3 by 3 )
= [tex]\frac{5}{2}[/tex] × [tex]\frac{1}{1}[/tex]
= [tex]\frac{5}{2}[/tex]
Answer:
162
Step-by-step explanation:
If it is 5/9 of the original number is 90 we can just divide 90 by 5 to find 1/9 and then we can multiply that with 9 to get 9/9 which is the whole number.
90 ÷ 5 = 18
18 × 9 = 162
Find the smallest number that must be added to 7653 to make it a perfect square? Explain.
Answers
9514 1404 393
Answer:
91
Step-by-step explanation:
√7653 is about 87.48
The next largest perfect square is 88^2 = 7744. The value that must be added to 7653 to get 7744 is ...
7744 -7653 = 91
Adding 91 to 7653 will make it a perfect square.

Answers
Irrational is √10, because
√9 = √3² = 3
√16 = √4² = 4
√25 = √5² = 5
√36 = √6² = 36
We can't anything with √10, eventually we can approx.
Answer:
option a
Step-by-step explanation:
[tex] \sqrt{9 } = \sqrt{ {3}^{2} } = 3 \\ \sqrt{16 } = \sqrt{ {4}^{2} } = 4 \\ \sqrt{25} = \sqrt{ {5}^{2} } = 5 \\ \sqrt{36} = \sqrt{ {6}^{2} } = 6 \\ \sqrt{10} = \sqrt{2 \times 5} [/tex]
Hence, √10 is irrational number.

A rectangular sticker has an area of 30 sq cm and it perimeter is 26 cm. what are the dimensions of the sticker?
#small Information
I know the equations but the problem I am not understanding it.. can you give a easier equations or method or more explanation of every equation..
Will give brainliest!!
Thank you :)
Answers
Answer:
Dimensions are 3cm and 10cm.
Step-by-step explanation:
We can make two equations for this problem.
ab = 30
2a + 2b = 26
Isolate a in the first equation.
a = 30/b
Plug that into the second equation.
2(30/b) + 2b = 26
2b^2 + 60 = 26b
2b^2 - 26b + 60 = 0
2(b - 3)(b - 10) = 0
b - 3 = 0 and b - 10 = 0
b = 3, 10
Plug these values into the first equation.
a3 = 30
a = 10
a10 = 30
a = 3
Best of Luck!

Find the equation of the line passing through the points with the given coordinates. Make sure your final answer
is in slope-intercept form.
(0,-4), (2,3)
Answers
Answer:
y = 7/2x - 4
Step-by-step explanation:
7/2 is the slope and -4 is the y intercept
Reason:
Slope = (y2-y1)/(x2-x1) or (3 - (-4)) / (2-0) = 7/2
b = -4, since you have (0,-4) as the x-intercept.

The Dallas Cowboys starting at the 20 yard line, ran two plays. The first play gained 10 yards, and after the second play the ball was placed at the 50 yard line. How many yards they gain on the second play?
Answers
=========================================================
Explanation:
They start on the 20 yard line. After the first play, they gain 10 yards and move to the 20+10 = 30 yard line.
After the second play, they must have gained 20 yards because 30+20 = 50.
Or you can think of it like 50-30 = 20, which shows the distance from the 30 yard line to the 50 yard line is 20 yards.
All of this assumes that the Cowboys started on their side of the field.
