C. 480

Explanation: I’m pretty sure you’re looking for the perimeter. Therefore, since you have a rectangle, you’ll have 4 sides. The measures are 100 by 140 so you’ll put 100 and 140 on the other sides and simply add them up.

Answer:

Mr. Lopez will need to fence 480 ft.

Step-by-step explanation:

We know that:

Perimeter of rectangle: 2L + 2B = 2(100) + 2(140)

On simplification:

2(100) + 2(140)
=> 200 + 280

Further simplification:

=> 480 ft.

Hence, Mr. Lopez will need to fence 480 ft.

Hoped this helped.

A box contains 5 red balls, 6 white balls and 9 black balls. Two balls are drawn at

valina [46]

Answer:

$P(Same)=\frac{61}{190}$

Step-by-step explanation:

Given

$Red = 5$

$White = 6$

$Black = 9$

Required

The probability of selecting 2 same colors when the first is not replaced

The total number of ball is:

$Total = 5 + 6 + 9$

$Total = 20$

This is calculated as:

$P(Same)=P(Red\ and\ Red) + P(White\ and\ White) + P(Black\ and\ Black)$

So, we have:

$P(Same)=\frac{n(Red)}{Total} * \frac{n(Red) - 1}{Total - 1} + \frac{n(White)}{Total} * \frac{n(White) - 1}{Total - 1} + \frac{n(Black)}{Total} * \frac{n(Black) - 1}{Total - 1}$

Note that: 1 is subtracted because it is a probability without replacement

$P(Same)=\frac{5}{20} * \frac{5 - 1}{20- 1} + \frac{6}{20} * \frac{6 - 1}{20- 1} + \frac{9}{20} * \frac{9- 1}{20- 1}$

$P(Same)=\frac{5}{20} * \frac{4}{19} + \frac{6}{20} * \frac{5}{19} + \frac{9}{20} * \frac{8}{19}$

$P(Same)=\frac{20}{380} + \frac{30}{380} + \frac{72}{380}$

$P(Same)=\frac{20+30+72}{380}$

$P(Same)=\frac{122}{380}$

$P(Same)=\frac{61}{190}$

Which is equivalent to 5(a + 6)? 1. a+30 2. 5a-30 3. 5a+6 4. 5a+30

Afina-wow [57]

Answer: the answer is number four.

Step-by-step explanation:

<h2>because when you take five multiply by A (5*a) you will get 5a and when you take five multiply by six (5*6) you will get 30 and there is positive sign so the plus (+) stays the same and your will be (5a+30) that is your answer. good luck.</h2>

SOLVE FOR X. pls i need help

Lyrx [107]

X=8
Set up proportions would give you: 10/3x+1 = 22/7x-1
With that in mind, cross multiply, which would give you: 10(7x-1) = 22(3x+1).
Turns into: 70x -10 = 66x+22. Then just solve for x

Using PYTHAGORAS THEOREM answer the question A vertical pillar ab bent at c at a height of 2.4m and its upper end b touches the

Alisiya [41]

Answer:

5.4 m

Step-by-step explanation:

The Pythagorean theorem tells you the relationship between the various lengths is ...

cd² = ac² +ad²

cd² = (2.4 m)² + (1.8 m)² = 9.00 m²

cd = √(9.00 m²) = 3.0 m

Since cd = cb and ab = ac+cb, we have ...

ab = 2.4 m + 3.0 m = 5.4 m

_____

You may recognize this as a 3-4-5 right triangle with a scale factor of 0.6. We are asked for the sum of the lengths of the "4" and "5" legs, which is ...

0.6·(4+5) = 5.4
