in Mike’s house are broken now. His father replaced 3/14 of the broken) .4 windows. Uncle Jack replaced 1/7 of the broken windows. Who replaced the greater fraction of the broken windows?

Answers

Answer:

Mike's father produces a greater fraction.

Step-by-step explanation:

Amount of windows replaced by Mike's father = 3/14

Amount of windows replaced by Uncle Jack = 1/7

This 1/7 can also be expressed as 2/14

Now, since they both have the same denominators, it means that the higher the numerator the greater than the other fraction.

Thus, 3/14 is greater than 2/14.

Hence, Mike's father replaced a greater fraction of the broken windows.

A vendor sells hot dogs and bags of potato chips. A customer buys 3 hot dogs and 5 bags of potato chips for $9.50. Another customer buys 2 hot dogs and 5 bags of potato chips for $8.00. Find the cost of each item.

Answers

Step-by-step explanation:

3d + 5p=9.50

2d + 5p=8

1 hot dog cost $1.50

2 × 1.50 + 5p = 8

3 + 5p = 8

5p = 8 - 3

5p = 5

p = 1

1 bag of potato chips cost $1.00

Answer:

6, 7, 2, 3

Step-by-step explanation:

supplementary means that two or more angles add together to equal 180 degrees

a straight line equals 180 degrees so the intersecting of a line creates two angles that are supplementary. That means <5 is supplementary with 6 and 7.

<5=<1 because the lines intersecting it are parrell. Using the same thinking process for angle 1 as above, it is supplementary with 2 and 3. and since 1 is equal to 5 it is also supplementary to 2 and 3.

Answer:

The solution of the given inequality

          x > 10

Step-by-step explanation:

Step(i):-

Given inequality  

                     3 ( x-8) > -4 + x

Multiply

                   3 x - 24 > -4 +x

subtract 'x' on both sides , we get

                 3 x - 24 - x > - 4 + x - x

        ⇒     2 x - 24 > - 4

Step(ii):-

Adding '2'4' on both sides , we get

        ⇒     2x - 24 + 24 > -4 +24

      ⇒     2 x > 20

Dividing '2' on both sides , we get

               [tex]\frac{2x}{2} > \frac{20}{2}[/tex]

                x > 10

Final answer:-

The solution of the given inequality

          x > 10

Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.

Answers

Answer:

114 units²

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, so

AB = CD , that is

13x - 7 = 5x + 9 ( subtract 5x from both sides )

8x - 7 = 9 ( add 7 to both sides )

8x = 16 ( divide both sides by 8 )

x = 2

Then

5x + 9 = 5(2) + 9 = 10 + 9 = 19

3x = 3(2) = 6

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height ), thus

A = 19 × 6 = 114 units²
