Divide 15 by 20 and then take that and multiply it by 16 and you'll get 12

when you have a problem like this and you need the smaller triangle measurements then the value from the smaller triangle will be on the top and if you need the larger triangle values then the larger value will be on top to find the ratios and multiply it by the other value from the denominator triangle

Answer:

45 km^2 (C)

Step-by-step explanation:

Isolate the smaller square -

We only need two side lengths, take 3km and 3km.

3×3 = 9km^2, that's the area of the smaller square.

Isolate the larger square -

Take 6km and the other 6km

6×6 = 36km^2

Add the square's areas together to get the whole area -

36 + 9 = 45km^2

All you need to do to solve these problems is to isolate the shapes and find their area's, and finally add them together.

Answer:

D. y = 3(1/3)x

Step-by-step explanation:

if x = -1

y = 9

A. y = (1/3) -¹ = 3 X

B. y = (1/3) -¹ + 2 = 5 X

C. y = (1/3) -¹ + 3 X

D. y = 3(1/3) -¹ = 9 ✓

So D is the answer

Diane's Tree Trimming Service has trimmed hundreds of trees in the Greater Denver area. The time it takes to trim a tree is norm

kkurt [141]

Answer: $P(28.5$ And we can find this probability with this difference:

$P(-0.7$

And in order to find these probabilities we use tables for the normal standard distribution, excel or a calculator.

$P(-0.7$

So then the best answer would be 21.82 %

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the time it takes to trim a tree of a population, and for this case we know the distribution for X is given by:

$X \sim N(32,5)$

Where $\mu=32$ and $\sigma=5$

We are interested on this probability

$P(28.5$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this: $P(28.5$ And we can find this probability with this difference:

$P(-0.7$

And in order to find these probabilities we use tables for the normal standard distribution, excel or a calculator.

$P(-0.7$

So then the best answer would be 21.82 %

Which statement best completes the sentence below? If the measure of /_4 is 70^o, then the measure of /_8 is _________________.

Alex_Xolod [135]

Answer:

As given, measure of angle 4 is 70°

Then what would be the measure of ∠8.

Following cases comes into consideration

1. If ∠4 and ∠8 are supplementary angles i.e lie on same side of Transversal, then

∠4 + ∠8=180°

⇒70°+∠8=180° [∠4=70°]

⇒∠8=180°-70°

⇒∠8=110°

2nd possibility

But if these two angles i.e ∠4 and ∠8 forms a linear pair.Then

⇒ ∠4 + ∠8=180°

⇒70°+∠8=180° [∠4=70°]

⇒∠8=180°-70°

⇒∠8=110°

3rd possibility

If ∠4 and ∠8 are alternate exterior angles.

then, ∠4 = ∠8=70°

4th possibility

If If ∠4 and ∠8 are corresponding angles.

then, ∠4 = ∠8=70°

Out of four options given Option A[ 110° because ∠4 and ∠8 are supplementary angles], Option B[70° because ∠4 and ∠8 are alternate exterior angles.] and Option D[70° because ∠4 and ∠8 are corresponding angles.] are Correct.
