Answers

Answer:

[tex]\mbox{\large \; 4\left(3x+5\right)\left(3x+5\right)} = 4(3x + 5)^2}[/tex]

Step-by-step explanation:

We are given the quadratic equation [tex]36x^2+120x\:+\:100[/tex] and asked to factor

Here are the steps

[tex]\mbox{\large \mathrm{Factor\:out\:common\:term\:}4:\quad 4\left(9x^2+30x+25\right)}}[/tex]
[tex]\mbox{\large\;\mathrm{Factor\:}9x^2+30x+25:\quad \left(3x+5\right)\left(3x+5\right)}[/tex]
[tex]\mbox{\large 36x^2+120x\:+\:100 = 4\left(3x+5\right)\left(3x+5\right)}[/tex]

Answer
[tex]\mbox{\large \; 4\left(3x+5\right)\left(3x+5\right)} = 4(3x + 5)^2}[/tex]

Answer: (6x+10)

Step-by-step explanation:

To find the side of the square, we have to first factorise it:

[tex]36x^2[/tex] + 120x + 100

= 36[tex]x^2[/tex] + 60x + 60x + 100

= 12x(3x + 5) + 20(3x + 5)

= (12x+20)(3x+5)

= 4(3x+5)(3x+5)

= 2(3x+5)2(3x+5)

= (6x+10)(6x+10)

∴ Hence, side = (6x+10) units

A rectangle has a width that is twice the length. If the area of the rectangle is represented by the expression 18x² + 48x + 32, what expression represents the length of the rectangle? Explain.

Answers

Answer:

Step-by-step explanation:

Length of rectangle = l (let length of rectangle be 'l')

Width of rectangle = 2l

Area of rectangle = lb --> l(2l)

∴ Here, the area is given = [tex]18x^2 + 48x + 32[/tex]

So,

Area of rectangle = lb

[tex]18x^2 + 48x + 32[/tex] = l x 2l

[tex]18x^2 + 48x + 32[/tex] = [tex]2l^2[/tex]

[tex]\frac{18x^2 + 48x + 32}{2}[/tex] = [tex]l^2[/tex]

[tex]\sqrt{\frac{18x^2 + 48x + 32}{2}}[/tex] = [tex]l[/tex]

∴ Length is [tex]\sqrt{\frac{18x^2 + 48x + 32}{2}}[/tex]

In the first week of July, a record 1,060 people went to the local swimming pool. In the second week, 105 fewer people went to the pool. In the third week, 135 more people went to the pool than in the second week. In the fourth week, 136 fewer people went to the pool than in the third week.

What is the percent change in the number of people who went to the pool between the first and last weeks?

Answers

Answer:

The percent change in the number of people who went to the pool

between the first and last week is 10% less

Step-by-step explanation:

The given is:

. In the first week of July, a record 1,060 people went to the local swimming

pool

In the second week, 105 fewer people went to the pool

⚫ In the third week, 135 more people went to the pool than in the second week

. In the fourth week, 136 fewer people

went to the pool than in the third week

We need to find the percent change in the number of people who

went to the pool between the first and last weeks

::There were 1060 people in the 1st week

There were 105 fewer people in the 2nd week .. The number of people in the 2nd week =

1060 - 105 = 955

.. There were 955 people in the 2nd week

:: There were 135 more people in the 3rd

week than the 2nd week

There were 955 people in the 2nd week

.. The number of people in the 3rd week = 955 + 135 = 1090

There were 1090 people in the 3rd week

:: There were 136 fewer people in the 4th week than in the 3rd week

There were 1090 people in the 3rd week

.. The number of people in the 4th week =

1090-136 = 954 .. There were 954 people in the 4th week

Let us find the change from 1st week to last week

: There were 1060 people in the 1 st week

There were 954 people in the last week

.. The change = 1060-954 = 106

:: Percent change =

Change

Original * 100%

.. Percent change = * 100%

106

1060 Percent change = 10%

The percent change in the number of people who went to the pool

Learn more:

between the first and last week is 10% less

To find the percent change in the number of people who went to the pool between the first and last weeks, we can use the formula:

percent change = (new value - old value) / old value x 100

First we need to find the number of people who went to the pool in the last week, which is the number of people who went in the first week minus 105, plus 135, minus 136.

So:

Last week = 1060 - 105 + 135 - 136 = 954

Then we can calculate the percent change:

percent change = (954 - 1060) / 1060 x 100 = -10%

So the percent change in the number of people who went to the pool between the first and last weeks is -10%. This means that the number of people who went to the pool in the last week is 10% less than the number of people who went in the first week.

V= 2799.16

V=πr^2h

You have the diameter which is 2 times to radius. In order to get the radius you half the diameter which is 9.

9 to the second power is 81. Then you multiply it by the height which is 11. 81 x 11 is 891. So 891 x pi would be about 2799.16.
The radius is half of the diameter;
2r=d 2 r = d.

So plug in 18m in as d.
2r=18
/2 /2
r= 9

The volume of a cylinder is v= πr^2h
Use Pi symbol in calculator unless specified to use 3.14
The height is 11m

V=πr^2h
V= π(9)^2(11)
V= π(81)(11)
V= π(891)
V= 2,799.159054348506
So, to the nearest whole number: v= 2,800 m

A. 100 lb.
B. 110 lb.
C. 120 lb.
D. 125 lb.

(Would like a explaination too btw)

Answers

The answer is B. Because the different in there weight is calculated by subtracting Randy’s weight ( 50 lb) from his fathers weight (160 lb ) which equals 110 lb.

Answer:

This looks pretty easy. Is this a trick question or what? I might be wrong but the answer seems to be B. 110 lb.

Step-by-step explanation:

Solution:

Given,

weight of Randy = 50 pounds

weight of his father = 160 pounds

difference in their weights = ?

Now,

difference in their weights =

weight of his father - weight of Randy

= 160 - 50

= 110 pounds

Therefore, the difference in their weights is 110 pounds.
