I need help with my homework

Answer:

20ml : 6ml: 15ml

Step-by-step explanation:

1000 milliters is 1 liter, so we would have to convert it to the ml so that it will all be in proportion. To simplify a ratio, divide by a number they can all be divided by. In this case, it was 10 first, so it made it 100: 30: 75. Then, to simplify it more, they can all be divided by 5, which is the lowest it can be since 20: 6: 15 have no numbers in common to be divided by.

Answer:

Area of triangle = 8.9

Area of parallelogram = 53.4 yd² (option A)

Step-by-step explanation:

✔️Area of the triangle = ½*base*height

base = 3 m

height = 5.9 m

Area of triangle = ½*3*5.9

Area of triangle = 8.85 ≈ 8.9 (nearest tenth)

✔️Area of parallelogram = base*height

base = 8.9 yd

height = 6 yd

Area of parallelogram = 8.9*6 = 53.4 yd²

Answer:

63 for the whole figure, for the different shaded regions it goes as follows, 17.5 for the white area and 45.5 for the grey area

Step-by-step explanation:

Answer:

(x+244)/y=3/2

x/y=3/5

y=5x/3

(x+244)/(x5/3)=3/2

x+244=3/2 . 5x/3

x+244=15x/6

6(x+244)=15x

6x+1464=15x

1464=15x-6x

1464=9x

x=1464/9

x≈ 162

mm=162*5/3=270

162:270 = 3:5

pm before = 270*3/2=405

405:270 = 3:2

Answer:

X=6

B=126

Step-by-step explanation:

8x+78°=2x+114°

8x-2x=114-78

6x=36

x=6

B=2(6)+114

B=12+114

B=126°

Note angle A and B are alternate angles and thus are equal

Answer:

since X=6 ,

2×6+114= 126 .

Answer:

x = 27°, ∠JLK = 55°

Step-by-step explanation:

From the diagram in the question above,

The exterior angle of a triangle is equal to the sum of the two opposite side

3x+13 = 39+(2x+1)

3x+13 = 40+2x

collect like terms and solve for x

3x-2x = 40-13

x = 27°.

∠JKL = 2x+1

Substitute the value of x

∠JKL = 2(27)+1

∠JKL = 54+1

∠JKL = 55°

Answer:

s(r(2)) = 6

Step-by-step explanation:

You would first solve for r(2). You then input r(2) which equals -2 into s(r(2)).

r(x)= -2x + 2

r(2)= -2(2) + 2

r(2)= -4 +2

r(2)= -2

s(x)=x² + 2

s(r(2)) = (-2)² +2

s(r(2)) = 6

Answer:

3+(-5)-7+6=3-5-7+6=-3

Answer and Step-by-step explanation:

First, get theta by itself.

θ = [tex]sin^{-1}(\frac{\sqrt{3} }{2} )[/tex]

Plug this into a calculator.

θ = 60°

To get it in radians, multiply 60 by [tex]\frac{\pi }{180}[/tex].

θ = [tex]\frac{1}{3} \pi[/tex] radians

Answer:

yes I can help you. the answer to the problem is 4/35.

Step-by-step explanation:

1. convert any mixed number into fractions.

your equation becomes 4/7÷5/1. this equals 4×1 over 7×5. multiply normally and your result is 4/35

Step-by-step explanation:

Answer:

y = 150x

Step-by-step explanation:

There is a proportional relationship between number of computers sold (x) and profit generated (y)

y ∝ x

y = kx

Here, k = proportionality constant

From the table given,

At y = 450 and x = 3,

450 = k(3)

k = 150

Therefore, expression that represents the proportional relationship will be,

y = 150x

Answer:

to find the area to the right positive z-score begin by reading off the area in the standard mormal distribution table, since the total area under the bell curve is 1 we subtract the area from the table from 1. for example the area to the left of z=1.02 is given in the table as 0.846

Answer:

2,285.7143

Step-by-step explanation:

There are two ways of doing this.

#1: Take 320, and divide it by the 14%. This should get you how many people are eqivlelent to 1 percent. When I did it out, 320/14 is equal 22.857143...

Remember this is 1%, and we need to find 100%. So we need to multiply the 1%, which was 22.857143, by 100.

This should get you 2,285.7143.

#2 Take your 100%, and divide it by the 14% that make up the 65+ population. This should get you 7.1428571.

Now you just have to multiply this number by the amount of 65+ residents, which is 320. So you should multiply 320x7.1428571.

This should get you the same exact answer, 2,285.7143

Answer:

AB = 9.5 units

Step-by-step explanation:

Here, we want to find the measure of AB

To do this, we are going to make use of the sine rule

for the sine rule, the ratio of the measure of a side and the sine of the angle that faces the side is a constant value for a triangle

Thus, we have it that; in a triangle ABC

a/sin A = b/sin B = c/sin C

using the triangle given;

we need the measure of the angle at C

The sum of angles in a triangle is 180

thus;

C + 93 + 48 = 180

C = 180 - 93 -48

C = 39 degrees

Now, to get the value of AB;

AB/sin 39 = 15/sin 93

AB = (15 * sin 39)/sin 93

AB = 9.5 units

Answer:

There can be 1365 different ways of choosing 11 players from a squad of 15. This means there can be 1365 eleven-member teams formed with 15 players.

Answer:

D. 28%

Step-by-step explanation:

675 people - 486 people that got in = 189 people left out

189 people out of 675 people = 189 / 675 = 0.28 or 28%
