PLEASE HELP The areas of two similar triangles are 50 dm2, and 32 dm2. The sum of their perimeters is 117 dm. What is the perime

Novosadov [1.4K]

Answer:

65 dm and 52 dm

Step-by-step explanation:

If the scale factor of the sides is k, then the scale factor of the areas is k^2.

The scale factor of the areas is (32 dm^2)/(50 dm^2) = 0.64 = k^2

The scale factor of the sides is k = \sqrt(0.64) = 0.8

The perimeters are in a ratio of 1:0.8

x + 0.8x = 117

1.8x = 117

x = 65

0.8x = 0.8(65) = 52

The perimeters are 65 dm and 52 dm.

Find the length of the third side. If necessary, write in simplest radical form. 8 17

statuscvo [17]

Answer:

Step-by-step explanation:

so we know that its a right triangle and 8 and $\sqrt{17}$ are not the hypotenuse.

the equation for this is $a^{2}$ + $b^{2}$ = $c^{2}$ with c being the hypotenuse.

$8^{2}$ + $\sqrt{17} ^{2}$ = $c^{2}$

64+17= $c^{2}$

81=c

$\sqrt{81}$ =c

9=c

A data set includes the following grades: 98, 94, 93, 82, 61, 80. Suppose that 61 is removed from the data. How is the median af

puteri [66]

Answer:

If we remove 61 from the data set, the median changes from 87.5 to 93.

Step-by-step explanation:

1. Let's calculate the median of the original data set:

Median = (3rd term + 4th term)/2 because the number of terms are even and our median mark is the average of the two middle marks, in this case, 82 and 93.

Median = (82 + 93)/2

Median = 87.5

2. Let's calculate the median of the data set removing 61:

Median = 3rd term because our median mark is the middle mark, in this case, 93. It is the middle mark because there are 2 scores before it (80 and 82) and 2 scores (94 and 98) after it.

Median = 93

In shipment of 850 widgets, 32 are found to be detective. At this rate, how many detective widgets could be expected in 22,000 w

cluponka [151]

Answer:

The number of detective widgets out of 22,000 widgets is 828 widgets

Step-by-step explanation:

Given as :

The total number of widgets = 850

The number of detective widgets out of 850 = 32

Now,

∵ Out of 850 widgets , the number of detective widgets = 32

SO,Out of 1 widgets , the number of detective widgets = $\frac{32}{850}$

∴ Out of 22,000 widgets , the number of detective widgets = $\frac{32}{850}$ × 22,000

Or, Out of 22,000 widgets , the number of detective widgets = 828.23

Hence, The number of detective widgets out of 22,000 widgets is 828 widgets Answer
