Answer: 3

Step-by-step explanation:

The larger triangle is 5 times the size of the smaller triangle. Notice 6 increased to 30. How? 5x6 = 30, so it increased in size 5 times. The rise of the larger triangle is 15. If we know that 15 is 5 times as large as the smaller rise, then 15 divided by 5 = 3. So the smaller rise is 3

Answer:

Missing rise is 3

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the cost of one t-shirt = t

And the cost of one sweatshirt = s

Since, Jayden sells 9 t-shirts and 3 sweatshirts for $420,

9t + 3s = 420

3t + s = 140 --------(1)

And Carson sells 1 t-shirt and 6 sweatshirts for $296,

t + 6s = 296 ----------(2)

Equation (1) multiplied by 6 then subtracted from equation (2)

(t + 6s) - 6(3t + s) = 296 - 6(140)

(t - 18t) + (6s - 6s) = 296 - 840

-17t = -544

t = $32

From equation (1),

3(32) + s = 140

s = 140 - 96

s = $44

This solution shows that cost one t-shirt is same for both sellers Carson and Jayden.

Answer:

A. 54 m^2

Step-by-step explanation:

You can do cross multiplication: [tex]\frac{4}{6}[/tex]×[tex]\frac{x}{9}[/tex]

4*9 = 6*x

36 = 6x

x = 6

That is the Width in m, so all you need to do is find the area!

Area = L * W

Area = 9 * 6

Area = 54

Answer:

B = 10.5

Step-by-step explanation:

From the figures, it looks like triangle HER is similar to triangle KPS.

From that we get

[tex] \dfrac{HE}{KP} = \dfrac{ER}{SP} [/tex]

[tex] \dfrac{B}{7} = \dfrac{7.5}{5} [/tex]

Multiply both sides by 7.

B = 10.5

Answer:

B = 10.5

C = 10

Step-by-step explanation:

When one divides the corresponding sides of similar triangles, one will attain the ratio of similitude. If one multiplies one of the similar triangle's sides by the ratio of similitude, then one will attain the corresponding side of the similar triangle. In simple terms, the ratio of similitude is the scaling factor between two similar polygons.

As per the given information, the two triangles are similar, therefore one can set up a proportion with their corresponding sides;

[tex]\frac{ER}{PS} = \frac{HE}{KP} = \frac{HR}{KS}[/tex]

Substitute;

[tex]\frac{7.5}{5} = \frac{B}{7} = \frac{15}{C}[/tex]

Solve for B with cross products;

[tex](7.5)(7) = (5)(B)\\52.5 = 5B\\10.5=B[/tex]

Solve with cross products for C;

[tex](7.5)(C) = (15)(5)\\7.5C = 75\\C=10[/tex]

The situations that describe a quantity that changes in an exponential manner relative to the other quantity are,

A. The value of a printer decreases in value by 15% each year.

E. The amount of money in Devonte's savings account in it he earns 3.5% interest each year.

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents is only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

The situations that describe a quantity that changes in an exponential manner relative to the other quantity are,

The value of a printer decreases in value by 15% each year,

It is an exponentially decaying function.

Suppose the first year it decayed to 85% of it's original value, next year it will decay 15% of 85% of its value.

The amount of money in Devonte's savings account it he earns 3.5% interest each year.

Suppose he earned 3.5% for $100, which is 103.5, next year he will earn

3.5% on $103.5, an exponentially growing function.

Answer:

21.9°

Step-by-step explanation:

In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet. Find the measure of ∠H to the nearest tenth of a degree.

We solve this above question using the Sine rule

a/sin A = b/sin B

In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet.

Hence:

HI/∠J = JH/∠H

= 8/sin 90° = 1.9/sin ∠H

Cross Multiply

∠H = arc sin(sin 1.9 × 90/8)

∠H = 21.9°

Step-by-step explanation:

Fist multiply 3 and .15 to get .45 for 3 pencils. Then subtract .45 from 6.45 and get 6. Then divided 6 by 5 to get 1.2 for each book

i think the answer is a: $1.20

my work:

3 x 0.15 = 0.45.

6.45 - 0.45 = 6.00

6.00 / 5 = 1.20

and i checked my work by doing 1.20 x 5 + 0.40 = $6.45.
