Is there someone that is on here that will help me with my geometry because I'm not getting any of this, please?

Answer:

r=−5.3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−7.4r−6.31=3.23−5.6r

−7.4r+−6.31=3.23+−5.6r

−7.4r−6.31=−5.6r+3.23

Step 2: Add 5.6r to both sides.

−7.4r−6.31+5.6r=−5.6r+3.23+5.6r

−1.8r−6.31=3.23

Step 3: Add 6.31 to both sides.

−1.8r−6.31+6.31=3.23+6.31

−1.8r=9.54

Step 4: Divide both sides by -1.8.

−1.8r/−1.8=9.54/−1.8

r=−5.3

Answer:

False

Step-by-step explanation:

4x4=16

16x4=64

5*5=25

64+25=89

Therefore the answer is false, because 89 is not equal to 95.

Answer:

false

Step-by-step explanation: you don't really need this part but all you need to know is that it is false :)

Step-by-step explanation:

80% of p = 20

=> 0.8p = 20, p = 20 / 0.8 = 25.

75% of b = 12

=> 0.75b = 12, b = 12 / 0.75 = 16.

Answer:

[tex]80\% \: of \: p = 20 \\ \frac{80}{100} p = 20 \\ \frac{4}{5} p = 20 \\ p = \frac{20 \times 5}{4} \\ \boxed{p = 25}[/tex]

[tex]75\% \: of \: b = 12 \\ \frac{75}{100} b = 12 \\ \frac{3}{4} b = 12 \\ b = \frac{12 \times 4}{3} \\ \boxed{b = 16}[/tex]

Answer:

The graph of the system in the attached figure

Step-by-step explanation:

we have

isolate the variable y

----> equation A

This is the equation of a vertical parabola open down (because the leading coefficient is negative)

The vertex represent a maximum

the vertex is the point (0,2)

---> equation B

This is the equation of a circle centered  at (0,0) with radius 3 units

The solution of the system of equations is the intersection points both graphs

using a graphing tool

The solutions are the points (-2.05,-2.19) and (2.05,-2.19)

see the attached figure

Answer:

x^2-6x+5

Step-by-step explanation:

To have roots at x=5 and x=1 you need to write is as follows

(x-5)(x-1)

you then need to multiply these two and get

x^2-6x+5

Step-by-step explanation:

Answer:

0.95

Step-by-step explanation:

The computation of the probability that a customer neither buys beer nor buys cigars is given below;

Given that, the probabilities are

The customers who purchased cigars be 0.02

The customers who purchased cigars + beer 0.50

And, the customers who purchased beer + cigars be 0.25

Now the probabilities where the customer purchased both

= 0.05 × 0.02

= 0.10

The probability where the customer purchased beer is

= 0.01 ÷ 0.25

= 0.04

Now the probability where a customer neither buys beer nor buys cigars is

= 1 - 0.02 + 0.04 - 0.01

= 0.95

Answer:

27

Step-by-step explanation:

i Think all are correct not sure tho

Answer:

See below.

Step-by-step explanation:

Note: I am considering that you are supposed to think of the graph maximum point as P(x, y) = P(0, 25).

It means that the absolute maximum at x = 0, so f(0) = 25.

What is the maximum of this graph and what does it represent?

When the ball is on the ground? No, once the maximum of this graph is 25 feet and the ground is 0 feet, the statement is false.

Where the ball ended? No, the final position is h = 0 feet, not h = 25 feet.

Where the ball started? Yes, the ball was dropped in h = 25 feet.

It represents the highest point on the graph? Yes.

25 feet? Yes.

i have a box and cremes

Answer:

x = -4

Step-by-step explanation:

[tex]x + 5 = 3x + 13[/tex]

Subtract [tex]3x[/tex] from both sides of the equation. You get:

[tex]-2x + 5 = 13[/tex]

Subtract 5 from both sides:

[tex]-2x = 8[/tex]

[tex]x = -4[/tex]

Answer:

13

Step-by-step explanation:

a^2+b^2=c^2

12^2+5^2=c^2

144+25=c^2

169=c^2

c=13

Answer:

13

Step-by-step explanation:

I am a little rusty on this but I think to solve youd do

12^2 which is 144 plus 5^2 which is 25, add together and get 169 and then find that the square root of 169 is 13.

Answer:

1920 toys

Step-by-step explanation:

Area of new toy chest :

Area = Length * width

Area = 3 feets * 2 feets

Area of new toy chest = 6 ft²

If ;

1 square foot requires 320 toys

6 ft² = (320 * 6) = 1920 toys

Answer: The bacony floor is 37 feet above the ground floor.

Step-by-step explanation:

Here, the ground level is marked as 0 feet.

The elevation of the balcony floor is 37 feet.

The elevation of the basement floor is -17 feet.

Since elevations relative to ground level at 0 feet.

i.e. elevation of balcony floor is same as the distance of balcony floor from ground.

That means the bacony floor is 37 feet above the ground floor.

Hence, the bacony floor is 37 feet above the ground floor.

Answer:

about 2.72 hours

Step-by-step explanation:

set up the equation:

40 + 55h = 190

subtract 40 from both sides

55h = 150

now divide both sides by 55

h =  2.72
