A total of 76 groom's guests and 64 bride's guests attended a wedding. The bride's guests used 96 tissues. The groom's guests us
mylen [45]

Answer:

The tissues each bride's guest used is 1.5.

Step-by-step explanation:

We are given that a total of 76 groom's guests and 64 bride's guests attended a wedding. The bride's guests used 96 tissues. The groom's guests used 152 tissues.

We have to find that approximately how many tissues each bride's guest used.

As we know that whenever we have to find the value of 'each item', we have to use division.

Number of bride's guests who attended a wedding = 64

Number of tissues used by the bride's guests = 96

So, the tissues each bride's guest used =  \frac{\text{Total tissues used by bride's guests}}{\text{Total number of bride's guests}}

                                                                    =  \frac{96}{64}

                                                                    =  \frac{3}{2}  =  <u>1.5</u>

Hence, each bride's guest used approximately 1.5 tissues.

. Write the quadratic equation in factored form. Be sure to write the entire equation. x^2 - 5x - 24 = 0
Viefleur [7K]

Answer:

(x+3)(x-8)=0

Step-by-step explanation:

First, write out the equation as it is given in the problem:

x^{2}-5x-24=0

Now, you have to split up the "-5x" to get to factored form.  The way to do this is to look for <em>the factors of "a" times "c" that sum to "b"</em>:

So, in this problem, a=1, b=-5, and c=-24.  So, find the factors of (1*-24) that sum to (-5). To clarify, (1*-24)=-24, so you have to find factorsof -24 that sum to -5.

Let's write out a list of factors.

1,-24---1+-24=-23no\\-1,24---1+24=23no\\2,-12---2+-12=-10no\\-2,12----2+12=10no\\3,-8---3+-8=-5yes

Therefore, our two factors will be 3x and -8x.

Now, let's rewrite our equation with these new factors in place of the -5x:

x^{2}-5x-24=0\\x^{2}+3x-8x-24=0

Next, find your factored expressions:

x^{2}+3x-8x-24=0\\(x^{2}+3x)(-8x-24)=0\\

Take the GCF from each set of parenthesis:

x(x+3)-8(x+3)=0

The GCFs that you took out will become your second in the set for factorde form.  It will be written as "x-8".

Therefore, your equation in factored form will be:

(x+3)(x-8)=0

The sum of the two areas of two circles is the 80x square meters. Find the length of a radius of each circle of them is twice as
Alborosie

Answer:

r = 4m --- small circle

R =8m --- big circle

Step-by-step explanation:

Given

Area = 80\pi\ m^2 -- sum of areas

R = 2r

Required

The radius of the larger circle

Area is calculated as;

Area = \pi r^2

For the smaller circle, we have:

A_1 = \pi r^2

For the big, we have

A_2 = \pi R^2

The sum of both is:

Area = A_1 + A_2

Area = \pi r^2 + \pi R^2

Substitute: R = 2r

Area = \pi r^2 + \pi (2r)^2

Area = \pi r^2 + \pi *4r^2

Substitute Area = 80\pi\ m^2

80\pi = \pi r^2 + \pi *4r^2

Factorize

80\pi = \pi[ r^2 + 4r^2]

80\pi = \pi[ 5r^2]

Divide both sides by \pi

80 = 5r^2

Divide both sides by 5

16 = r^2

Take square roots of both sides

4 = r

r = 4m

The radius of the larger circle is:

R = 2r

R =2 * 4

R =8m

Please help me find x
alisha [4.7K]

Answer: 16.6

Step-by-step explanation:

a² + b² = c²

7² + b² 18²

49 + b² = 324

Subtract 49 from both sides

b² = 275

√b² = √275

b = 16.583

16.583 ≈ 16.6
