Cd + z = m - cb
cb + z - m = cb
z - m = cb + cb
z - m = c(d + b)

c = (m - z)/(d + b)

Find the missing value

yawa3891 [41]

It is easier to write the equivalent ratios first, then use that information to find the missing values.

3. ratio: cars/trucks = 3/5, or trucks/cars = 5/3. Missing value: 6/3*5 = 10.

4. ratio: TVs/Computers = 2/7, or Computers/TVs = 7/2. Missing value: 21/7*2 = 6.

Point D is the incenter of triangle BCA. If m∠FDG = 136°, what is the measure of ∠FHG?

nikdorinn [45]

Given:

Point D is incenter of ΔBCA.

m∠FDG = 136°

To find:

The measure of ∠FHG

Solution:

<em>Angle subtended by the arc at the center is twice that subtended on the remain part of the circle.</em>

$\Rightarrow m\angle FDG = 2 m\angle FHG$

Divided by 2 on both sides.

$$\Rightarrow \frac{1}{2} m\angle FDG = \frac{1}{2} \times 2 m\angle FHG$

$$\Rightarrow \frac{1}{2} m\angle FDG = m\angle FHG$

Substitute m∠FDG = 136°

$$\Rightarrow \frac{1}{2} (136^\circ)= m\angle FHG$

$$\Rightarrow 68^\circ= m\angle FHG$

The measure of ∠FHG is 68°.

Loretta has a patio in the shapea trapezoid. The floor of the patio is shown in the sketch below.12 feet5 feetWood PlanksBrick15

beks73 [17]

We can calculate the width of the rectangle patio with pythagorean theorem:

$\begin{gathered} \text{Base of triangle=15-12=3} \\ c^2=a^2+b^2 \\ 5^2=3^2+b^2 \\ b=\sqrt[]{25-9} \\ b=\sqrt[]{16} \\ b=4 \end{gathered}$

Then, she need to put trim on the edge of the floow of the patio that is wood planks and DOES NOT share and edge with the brick part:

$\begin{gathered} T=12+4+12 \\ T=28\text{ feet} \end{gathered}$

Loretta need to put 28 feet of trim.

Which is equivalent to 80 Superscript one-fourth x?

Neporo4naja [7]

Answer:

The equivalent statement is $(\sqrt[4]{80})^{x}$ ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- Any root can be a fraction power

- Ex: $\sqrt{a}=a^{\frac{1}{2}}$

$\sqrt[3]{a}=a^{\frac{1}{3}}$

$\sqrt[4]{a}=a^{\frac{1}{4}}$

$\sqrt[n]{a}=a^{\frac{1}{n}}$

* The expression is $(80)^{\frac{1}{4}x}$

∵ $(80)^{\frac{1}{4}x}$ can be written as $(80^{\frac{1}{4}})^{x}$

∵ $(80)^{\frac{1}{4}}=\sqrt[4]{80}$

∴ $(80^{\frac{1}{4}})^{x}$ = $(\sqrt[4]{80})^{x}$

* The equivalent statement is $(\sqrt[4]{80})^{x}$

Write the equation of the line passing through the point (2,−1)(2,−1) with a slope of −3−3

Sav [38]

Answer:

y = -3x + 5

Step-by-step explanation:

point-slope formula: y-y1 = m(x-x1)

y-(-1) = -3(x-2)

y+1 = -3x + 6

y = -3x + 5
