Answer:

Step-by-step explanation:

The word elevation means above or on top.

This means our answer must be a positive so option C is eliminated.

Sea level is 0 ft

So we can make an equation with x as our unknown:

x = sea level + feet elevated

x= 0 + 373

x =373

Therefore Option D is the correct answer

I have 1 hundreds, 9 tens, 9 ones, 8 tenths and 1 hundredths. What number am I?

kkurt [141]

Answer: 199.81
Given:
1 hundred
9 tens
9 ones
8 tenths
1 hundredths
thus;
1 hundred = 1 x 100 = 100
9 tens = 9 x 10 = 90
9 ones = 9 x 1 = 9
8 tenths = 8 x 1/10 = 8/10 or .8
1 hundredth = 1 x 1/100 = 1/100 or .01

add: 100 + 90 + 9 + .8 + .001 = 199.81
That is: one hundred ninety-nine and eighty-one hundredths

Please help. All you have to do is write a simple expression but I don't fully under stand it so please help me. This is due tod

Semenov [28]

Answer:

1497 - 202

Step-by-step explanation:

The question is saying that the Las Vegas trip was longer so we know to put that first in the expression

we can also tell that the question is asking us for the difference (aka subtraction) between the two trip by the key words how much longer

and then it tells us that we are finding the difference between Las Vegas and Cheyenne so we know to use those two numbers

that is how we come up with the expression 1497 - 202

PLSS help me with this question?

Xelga [282]

Answer:

Part a) By alternate interior angles

Part b) By vertical angles

Part c) By AAA (Angle-Angle-Angle) Similarity Theorem

Part d) Triangles ABC and CDE are similar

Part e) $b=\frac{2DE}{3}$ or $b=\frac{15}{AC}$

Step-by-step explanation:

Part a)

we know that

If AB is parallel to DE

then

m<1=m<4 ------> by alternate interior angles

Part b)

we know that

m<5=m<6 -------> by vertical angles

Part c) we know that

The two triangles are similar by AAA (Angle-Angle-Angle) Similarity Theorem ------> The three corresponding angles are equal

m<1=m<4

m<5=m<6

m<3=m<2

Part d) we know that

If two figures are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

therefore

Triangles ABC and CDE are similar

Part e) Find the length side of b

Remember that

If two figures are similar, then the ratio of its corresponding sides is equal

$\frac{AB}{DE}=\frac{BC}{DC}=\frac{AC}{CE}$

substitute the values

$\frac{3}{DE}=\frac{2}{b}=\frac{AC}{7.5}$

$b=\frac{2DE}{3}$

$b=\frac{2*7.5}{AC}=\frac{15}{AC}$
