4 1/2 ​ ÷(−1 3/7​ ) please help and hurry

Answers

Answer 1

Hi! I'm happy to help!

To first solve this, we need to make those mixed numbers improper fractions.

To make 4 1/2 an improper fraction, you have to turn 4 into halves (multiply four by 2) then add the extra half, giving you 9/2.

[tex]\frac{9}{2}[/tex]​ ÷(−1[tex]\frac{3}{7}[/tex]​ )

Now, we turn 1 3/7 into an improper fraction. We turn 1 into sevenths (multiply 1 by 7) then add the other 3 sevenths, giving you 10/7.

[tex]\frac{9}{2}[/tex]​ ÷(−[tex]\frac{10}{7}[/tex]​ )

From here, we need to turn this problem into a multiplication problem in order to solve. Since multiplication is the opposite of division, we need to get the opposite of something, so we use our second fraction and flip it.

[tex]\frac{9}{2}[/tex]​ ×(−[tex]\frac{7}{10}[/tex]​ )

Now, we multiply the top by the top, and the bottom by the bottom. (any positive multiplied by a negative gives a negative)

-[tex]\frac{63}{20}[/tex]

Since we cannot simplify, our final answer is -63/20.

I hope this was helpful, keep learning! :D

Steve and his friends measured a snow pile; it was 7 feet tall. The next day, the
snow pile was only 6.5 feet tall. What was the percent of decrease in the snow
pile? Round your answer to the nearest tenth

Answers

The percentage decrease is 7.14%

First measurement = 7 feet

Second measurement = 6.5 feet

Difference in measurement = 7 feet - 6.5 feet = 0.5 feet

Percentage decrease = Difference in measurement/ First measurement × 100

= (0.5/7.0) × 100

= 7.14%

The percentage decrease is 7.14%

How is constructing an angle bisector similar to constructing a perpendicular bisector?
A. Both constructions begin with a given angle
B. Both constructions allow you to find the midpoint of a segment.
C. Both constructions require that you draw a ray.
D. Both constructions require the point where two arcs intersect.

Answers

Answer:

D. Both constructions require the point where two arcs intersect.

Step-by-step explanation:

D is your answer

Both constructions require the point where two arcs intersect. Then the correct option is D.

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Building an angle bisector is similar to building a perpendicular bisector in that both constructs call for the intersection of two arcs.

Angle bisector means dividing an angle into two equal parts. And the perpendicular bisector means the line is divided into two equal line segments.

Both constructions require the point where two arcs intersect.

Then the correct option is D.

convert 5476 to base seven​

Answers

Assuming 5476 is given in base 10.

We have

5476 = 2×2401 + 674 = 2×7⁴ + 674

674 = 1×343 + 331 = 1×7³ + 331

331 = 6×49 + 37 = 6×7² + 37

37 = 5×7 + 2 = 5×7¹ + 2

2 = 2×1 = 2×7⁰

so that
