If you need the answer only, you can just scroll to the bottom.

So, we know that a right angle is 90 degrees, and we know that it is divided in two parts. So, we must set up the equation knowing the angles.
3x + 60 = 90.
So, we need to begin simplifying the equation until we have isolated the variable. We can start by subtracting 60 from 90 to get rid of the 60 on the left side of the equation.
90 - 60 = 30.
So, our simplified version is:
3x = 30.
So, we need to isolate the variable. To do that, we must divide both sides by 3.
3x/3 = 1x = x.
So, we have :
X = 30/3.
Simplify 30/3.
30/3 = 10.
So:
X = 10

10 because a right angle = 90 degrees. and 90 - 60 = 30. 30 / 3 =10

The area of Maxine's living room is 88 square feet. The length of the room is 3 feet longer than the width. Which quadratic equa

lorasvet [3.4K]

Answer:

Correct answer is option (B)

Step-by-step explanation:

We have been given that area of Maxine's living room is 88 square feet. Further, we are given that length of the room is 3 feet longer than the width.

Let us assume that x be the width of the room, therefore, length of the room will be $x+3$ .

We know that area of a rectangle can be found by multiply the measures of length and width, therefore, we can set:

$\text{Area} = \text{length}\times \text{width}\\\text{Area} = (x+3)\times x\\\text{Area} = x^{2}+3x\\$

Now, since we are given that area is 88 square feet, therefore, we can set this expression for area equal to 88 to get the desired equation:

$x^{2}+3x=88$

Therefore, correct answer is option (B)

Bill needs to find the area of the ground covered by a conical tent. The tent is 12 feet tall and makes a 70° angle with the gro

LiRa [457]

To get the area of the cone we need to find the radius first.

tan 70=r/12

r=12tan 70

area of a circle is given by:

A=πr²

thus the area of the ground covered by the tent will be:

A=π(12tan70)²

The answer is

A] A=π(12tan70°)²

the price of milk in 2013 was around $3.28 a gallon. This was eight times as much as you would have probably paid for a gallon o

Jlenok [28]

The cost of the milk is $\fbox{\$\,0.41{\text{ a gallon}}}$ in 1950s.

Further explanation:

The price of milk in 2013 was around $\$3.28$ a gallon.

And it is given that this was eight times as much as one can would have probably paid for a gallon of milk in the 1950s.

It is given that the price of milk in 2013 is $\$3.28$ a gallon.

Assume the price of milk in 1950 be $\$x$ a gallon.

Now, given that 8 times of $x$ is the price of milk in 2013.

Therefore, $8x$ is the price of milk in 2013 and also $\$3.28$ is the price of milk in 2013.

Equating $8x$ and $\$3.28$ equal as both are the price of milk in 2013 as,

$\begin{aligned}8x&=3.28\\x&=\frac{{3.28}}{8}\\x&=0.41\\\end{aligned}$

Here, x is the price of milk in 1950.

Therefore, the cost of the milk is $\fbox{\$\,0.41{\text{ a gallon}}}$ in 1950s.
