Mathematics
1 answer:
Sergeu [11.5K]1 year ago
6 0

Answer:

The base length of the larger parallelogram is 112 centimeters

Step-by-step explanation:

Since the ratio is 4:1, we multiply the length of the smaller base (28), by 4 to find the length of the larger base.

4 x 28 is 112.

Hope this helped!

Two lengths of a triangle are shown.
Solnce55 [7]

Answer:

11 ft

Step-by-step explanation:

Given the two lengths of a triangle as

AB = 6ft

AC = 6ft

This is an isosceles triangle because only 2 sides are equal.

In an isosceles triangle, the sum of 2 (sides) lengths must be greater than the other length.

Therefore, let's assume the following:

i) AC + AB > BC

6 + 6 > BC

12 > BC (BC is less than 12)

BC < 12

ii) BC + AC > AB

BC + 6 > 6

BC > 6 - 6

BC > 0

Therefore the range of values for BC =

0 < BC < 12

Since BC must be bigger than one of the lengths and it must also be less than the sum of the 2 sides. The length of BC could be 11 because it is less than (6+6) 12 and greater than 6.

Use the arithmetic progression formula to find the sum of integers from 75 to 100.75,76,77....99,100.​
Sophie [7]

Answer:

The sum is 2275

Step-by-step explanation:

Given

75,76,77....99,100

Required

The sum

Using arithmetic progression, we have:

S_n = \frac{n}{2}(T_1 + T_n)

Where:

T_1 = 75 --- first term

T_n = 100 --- last term

n = T_n - T_1 + 1

n = 100 - 75 + 1 = 26

So, we have:

S_n = \frac{n}{2}(T_1 + T_n)

S_n = \frac{26}{2}*(75 + 100)

S_n = 13*175

S_n = 2275

Sienna planned a rectangular pool, as shown in the scale drawing below. 11 in. 7 in. Sienna used the scale drawing above to crea
Andreas93 [3]

Given that Sienna planned a rectangular pool drawn on a scale 11 inches long by 7 inches wide, and Sienna used the scale drawing above to create a pool that is 14 ft wide x 22 ft long, and she then decided to make a pool with a final length of 33 ft, to determine which expression finds the change in scale factor for the longer pool Sierra is building the following calculation must be performed:

  • 11 inches = 0.916 feet
  • 11 / 0.916 = 12
  • 7 inches = 0.583333 feet
  • 7 / 0.5833333 = 12
  • Thus, the initial scale is 1:12.
  • 33 / 0.916 = 36

Therefore, the scale factor went from 1:12 to 1:36.
