I WILL GIVE BRAINLIEST ONLY IF YOUR CORRECT

Mathematics
1 answer:
Shalnov [3]3 years ago
6 0

Answer: C) 7.5 feet

Step-by-step explanation:

1. You know that the triangles are similar. Therefore, to calculte the lenght of her puddle (which is identified in the figure as <em>l</em> ), you can set up the following proportions:

\frac{l}{5ft}=\frac{12ft}{8ft}

2. Now, you must solve for <em>l. </em>Then you obtain that the result is:

l=\frac{(5ft)(12ft)}{8ft}\\l=7.5ft

3. The answer is the option C.

Find two consecutive whole numbers that<br> 19 lies between
sertanlavr [38]

Answer:

I don't believe that this is possible unless the answer you are looking for is 18, 20.

Step-by-step explanation:

The meaning of cosecutive whole numbers is a whole number followed directly after another. 14, 16, 18 are not consecutive though they are each spaced from each other by 2.

Using Slopes of Parallel Lines Quick Check
Semenov [28]

Answer:

The answer is (B) ⇒ Yes. AB is parallel to CD and AD is parallel to BC

Step-by-step explanation:

<em>There is an important fact about the parallel lines: </em>

  • Parallel lines have equal slopes

<em>The rule of the slope of a line is:</em>

  • m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}, where (x_{1},y_{1}) and (x_{2},y_{2}) are two points on the line

<em>Let us use the fact and the rule to solve the question</em>

∵ ABCD is a quadrilateral

∵ A = (0, 2) , B = (2, 6), C = (9, 6), D = (7, 2)

∵ The opposite sides are AB, CD and AD, BC

Find the slopes of the four sides to check the parallel sides

∵ m_{AB}=\frac{6-2}{2-0}=\frac{4}{2}=2

∵ m_{CD}=\frac{2-6}{7-9}=\frac{-4}{-2}=2

∵ The slope of AB = The slope of CD

∴ AB // CD

∵ m_{AD}=\frac{2-2}{7-0}=\frac{0}{7}=0

∵ m_{BC}=\frac{6-6}{9-2}=\frac{0}{7}=0

∵ The slope of AB = The slope of CD

∴ AD // BC

The correct answer is:

Yes. AB is parallel to CD and AD is parallel to BC ⇒ (B)

-3(-6b+5)? Solve bih
madam [21]

Answer:

18b - 15

Step-by-step explanation:

<u>Step 1:  Distribute </u>

-3(-6b + 5)

(-3 * -6b) + (-3 * 5)

18b - 15

Answer:   18b - 15

<u>If needed solve for b </u>

18b - 15 + 15 = 0 + 15

18b / 18 = 15 / 18

b = 0.8333...
