2 in 2:3 is the amount of blue paint

3 in 2:3 is the amount of yellow paint

Figure out how many times to multiply 2 to get 16:

16/2=8

Now, multiply 3 by 8, which would be equal to 24.

Ratio: 16:24

Answer:

prey and predators depends in each other .in the absence of one another is useless or meaning less. predators is responsible for population of prey.if less predators more prey and more predators means less prey.

Answer:

A predator-prey relationship tends to keep the populations of both species in balance. ... As the prey population increases, there is more food for predators. So, after a slight lag, the predator population increases as well. As the number of predators increases, more prey are captured.

Step-by-step explanation:

(90 - 72)/90 = P/100

Let P = percentage

18/90 = P/100

90P = 100(18)

90P = 1,800

P = 1,800/90

P = 20

Now 100% - 20%

You sold 80% of the boxes of fruits.

Answer:

To make it easier, lets say Justin = J, Eva = E, and Emma = M. Then, J = E + 7.50 M = J -12 J + E + M = 63 You can substitute for M in the third equation using the second equation, and you get: J + E + J - 12 = 63 Clean it up a little bit and you get: 2J + E = 75 You know J = E + 7.50, so substitute that for J and you get: 2(E + 7.50) + E = 75 2E + 15 + E = 75 3E + 15 = 75 3E = 60 E = 20 ; meaning that Eva has $20. Justin has $7.50 more than Eva, so he has $27.50. Emma has $12 less than Justin, so Emma has $15.50. Double check your answer by making sure they all add up to 63, which they do.

Answer:

The better buy is to buy 10 kilograms of potatoes at $ 3.92, since each kilogram costs $ 0.392.

Step-by-step explanation:

To find the cost per unit in each case and then state which is the better buy, the following calculations must be performed:

6kg of potatoes for $ 2.45:

2.45 / 6 = 0.408

15 kg of potatoes for $ 5.9:

5.90 / 15 = 0.393

10 kg of potatoes for $ 3.92:

3.92 / 10 = 0.392

Thus, the better buy is to buy 10 kilograms of potatoes at $ 3.92, since each kilogram costs $ 0.392.

Answer:

A. 3/12

Step-by-step explanation:

1/4 x 3 for the three different bags and each bag having 1 crayon that's the color green it's 1/4 however due to there being 4 crayons in each bag

the only other answer could be 1/4 when simplified

Answer:

Step-by-step explanation:

1 bag of crayons = 4 crayons = 100% (10/10)

1/4 bag of crayons = 1 crayon = 25% = 1 green crayon per bag

3 bags of crayons = 12 crayons (3 x 4)

if 1 bag has 1 green crayon and there are 3 bags then there are 3 green crayons

Answer:

300 masks

Step-by-step explanation:

If 267 is 89% of the whole amount, we can set up the following proportion:

[tex]\frac{89}{100} =\frac{267}{x}[/tex], where x is the total amount of masks we need to find.

If we cross-multiply, we get 26700=89x. Divide both sides by 89, and we get 300. So, Cameron has a total of 300 masks in his collection.

I hope this helped.

Answer:

300 masks

Step-by-step explanation:

89% = 0.89

( / ) = divided by

267/total amount of masks = 0.89

267/0.89 = 300

300 masks in total

Answer:

140

Step-by-step explanation:

30% of a number(x) is 105. To find the number(x) we must set up the equation below and solve for x:

0.3=105/x (multiply x)

0.3x=105 (divide by 0.3)

x=350

Solve for 40% of the number by multiplying 0.4 by the number:

350x.4=140

Answer:

146.96 [tex]m^2[/tex]

Step-by-step explanation:

1. Approach

Divide this figure into two smaller shapes. Calculate the area of these smaller shapes, and then add the results. One can divide this shape into a semi-circle, and a triangle.

2. Area of the triangle

The formula to find the area of a triangle is;

[tex]\frac{base*height}{2}[/tex]

It is given that the base of the triangle is (14m) and the height is (10m). Substitute in these values, and solve for the area,

[tex]\frac{14*10}{2}\\= \frac{140}{2}\\= 70[/tex]

2. Area of the semi-circle

The area of the semi-circle can be found by finding the area of the larger circle, and then divide it by 2, since a semi-circle is half of a circle. The formula for the area of a semi-circle is;

[tex]\frac{(pi)(r^2)}{2}[/tex]

Where (pi) is the constant (3.1415...), (r) represents the radius of the circle, which by definition is half of the diameter. Substitute in the values and solve;

[tex]\frac{(pi)(7)^2}{2}\\= \frac{3.14*49}{2}\\=76.96[/tex]

3. Find the total area;

Now add up the two values for the area of the figures;

Triangle + Semi-circle

= 70 + 76.96

= 146.96

Answer: about 147 m²

Step-by-step explanation:

Cos Milky said it. Trust Milky. Milky Smart.

Answer:

r = 4 units

Step-by-step explanation:

Volume of cone = 201.06 cubic units

Height (h) = 12 units

Radius (r) = ?

Thus, formula for volume of cone = ⅓*πr²h

Plug in the values and solve for r

⅓*π*r²*12 = 201.06

r²*4*π = 201.06

r²*12.57 = 201.06

Divide both sides by 12.57

r² = 201.06/12.57

r² = 15.9952267

r = √15.9952267

r ≈ 4 units

Step-by-step explanation:

I just got it on a pex. JK=RS. KL=ST. K=S. those are the answers

The congruences that are true by CPCTC are:

∠L = ∠R

KL ≅ ST

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

If ΔJKL = ΔRST, then the corresponding parts of the triangles are congruent.

CPCTC stands for "corresponding parts of congruent triangles are congruent,"

So we can use this property to determine which congruences are true.

∠L = ∠R:

This is true by CPCTC because they are corresponding angles in congruent triangles.

JK ≅ RS:

This is not true by CPCTC because they are not corresponding sides in congruent triangles.

KL ≅ ST:

This is true by CPCTC because they are corresponding sides in congruent triangles.

JL ≅ RS:

This is not true by CPCTC because they are not corresponding sides in congruent triangles.

∠L = ∠S:

This is not necessarily true just by the fact that ΔJKL = ΔRST.

It could be true in some cases, but it is not guaranteed by CPCTC.

Therefore,

The congruences that are true by CPCTC are:

∠L = ∠R

KL ≅ ST

Answer:

1/5 hr or 12 min

Step-by-step explanation:

We are going to use the formula D = RT

Let t = the time for  them to be 2 mi. apart

Then 7t = the distance the ranch hand traveled

and 3t = the distance the cows traveled

Since they traveled in opposite directions, the sum of their distances will give us how far they are apart.

So, 7t + 3t = 2

10t = 2

t = 2/10 = 1/5 hr. =  12 min.
