Answer/Step-by-step explanation:

The rhombus when split into two triangles will give us two equilateral triangles that are congruent to each other.

Therefore:

The two bases of both triangles will have equal angle measures of 4x + 5 each and a third angle measure of 8x - 6.

✅Formula to find the value of x:

(8x - 6) + 2(4x + 5) = 180° (sum of triangle)

8x - 6 + 8x + 10 = 180

8x + 8x - 6 + 10 = 180

16x + 4 = 180

16x + 4 - 4 = 180 - 4

16x = 176

16x/16 = 176/16

x = 11

If 3t=5t-8 evaluate -4t+5
Sergio [31]

3t = 5t - 8

-2t = -8

t = 4

Now put that into -4t + 5:

-4t + 5

-4(4) + 5

-16 + 5

-11

Ben can type 153 words in 3 minutes. at this rate, how many words can he type in 10 minutes?
Alexxandr [17]

Answer:

Ben can type 510 words in 10 minutes.

Step-by-step explanation:

The relation between the number of words typed and the minutes is direcltly proportional, that is, with Ben type more minutes, he will end up typing more words.

Thus, we can use the rule of three:

words    |    minutes

 153      ---      3

    x       ---      10

 

Now, we can just cross multiply them:

153~ x~10 = x~ times~3

1530 = 3x\\3x= 1530\\x=\frac{1530}{3} \\= 510

Thus, Ben can type 510 words in 10 minutes.

Robin’s scores: 99, 108, 102, 107, 119 Mean = 107; MAD = 5. 2 Evelyn’s scores: 125, 137, 138, 145, 145 Mean = 138; MAD = 5.
stiks02 [169]

The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean.

The MAD implies that Evelyn scores are more spread out than Robin scores.

The given parameters:

  • <em>Robin scores = 99, 108, 102, 107 119</em>
  • <em>Mean of Robin score, = 107</em>
  • <em>Mean absolute deviation = 5.2</em>
  • <em>Evelyn scores = 125, 137, 138, 145</em>
  • <em>Mean of Evelyn score = 5.6</em>

The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean. It implies the absolute distance from the mean of the data set.

The absolute distance of Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

Thus, we can conclude that Evelyn scores are more spread out than Robin scores.

A student bought 34 pencils for school.if he sharpened 16 of the pencils before school whats is his ratio of unsharpened pencils
Sergio [31]


he bought 34 pencils which I suppose aren't already sharpened

so if he sharpens 16 of them just subtract 16 from 34 (34-16) which equals 18

so the ratio would be 16:18

but if u need to simplify it would be 8:9
