Answer:

A. 10

<em>Brainliest, please!</em>

Step-by-step explanation:

(1, 2)(x, 5) = 1/3

5 - 2 / x - 1 = 1/3

3 / x - 1 = 1/3

x - 1 = 3 / 1/3

x - 1 = 9

x = 9 + 1

x = 10

Perpendicular lines have gradients that multiply to make -1. In this case 1/3 x -3 = -1
(5 - 2)/(x - 1) = -3
3 / (x - 1) = -3
So (x - 1) = -1
x = 0

Answer:

x = 22

Step-by-step explanation:

The figure is attached below.

Its given that SV is parallel to RU. We have to find the value of x.

Observe that, if we join point V to U, we will obtain a parallelogram RSVU. One of the properties of a parallelogram is that the sum of its two adjacent angles is always 180 degrees.

So, the two adjacent angles would be: ∠S and ∠R

From the figure:

∠S = 5x + 4

∠R = 44 + x

Since,

∠S + ∠R must be 180 degrees, we can write:

∠S + ∠R = 180

5x + 4 + 44 + x = 180

6x + 48 = 180

6x = 132

x = 22

Therefore, the value of x is 22.

You have a hemisphere with a volume of 6. What is the surface area with a sphere with the same diameter. Round to the nearest th

Vikki [24]

Answer:

(the volume of the hemisphere has no units, so i will suppose that it is 6m^3)

For a sphere of radius R, the volume is:

V = (4/3)*pi*R^3

Where pi = 3.14

And a hemisphere is half of a sphere, then the volume of a hemisphere of radius R is:

V = (1/2)*(4/3)*pi*R^3

We know that the volume of the hemisphere is 6 m^3, then we have the equation:

6 m^3 = (1/2)*(4/3)*3.14*R^3

Now we can solve this for R.

6 m^3 = 2.1*R^3

∛(6 m^3/2.1) = R = 1.41 m

The radius of the hemisphere is 1.41m

Now we want to find the surface of a sphere with this radius (if the radius is the same, then the diameter is the same)

For a sphere of radius R, the surface is:

S = 4*pi*R^2

Then the surface of this sphere is:

S = 4*3.14*(1.41 m)^2 = 24.971 m^2

A florist is making 5 identical bridesmaid bouquets for a wedding. she has $610 to spend (including tax) and wants 24 flowers fo

Dafna11 [192]

R + t + L = 5(24).....r + t + L = 120
6r + 4t + 3L = 610
r = 2(t + L).......r = 2t + 2L

2t + 2L + t + L = 120
3t + 3L = 120

6(2t + 2L) + 4t + 3L = 610
12t + 12L + 4t + 3L = 610
16t + 15L = 610

16t + 15L = 610
3t + 3L = 120 ...multiply by -5
-------------------
16t + 15L = 610
-15t - 15L = - 600 (result of multiplying by -5)
-------------------add
t = 10

3t + 3L = 120
3(10) + 3L = 120
30 + 3L = 120
3L = 120 - 30
3L = 90
L = 90/3
L = 30

r = 2(t + L)
r = 2(10 + 30)
r = 2(40)
r = 80

so for all the bouquets, there are 80 roses, 30 lillies, and 10 tulips....but there are 5 bouquets...

so each bouquet has :
80/5 = 16 roses <==
10/5 = 2 tulips <==
30/5 = 6 lillies <==

Tell what part of the circle is shaded

DIA [1.3K]

Answer:

Fraction = 1/4, Decimal = 0.25, Percent = 25%

Step-by-step explanation:

Given the picture, we can see the circle is divided into four pieces. One of the pieces is shaded. So, since we have one out of four pieces shaded, we would represent this as 1/4 as a fraction. As a decimal, enter 1 divided by 4 into your calculator, and it will give you 0.25. To find a percentage value, take your decimal and multiply it by 100. 0.25*100= 25%
