The area of a triangle can be calculated through the equation,
                            A = bh / 2
where A is area, b is base, and h is height. 
Substituting the known values from the given above to the equation
                            A = (14 in)(6 in) / 2 = 42 in²
Since, there are five of these triangles, the total area is,
                            total area = 5(42 in²) = 210 in²
Thus, the total area of the plywood needed is 210 in².

Can someone explain to me how to solve this equation<br>15x +-6 = 8​
soldier1979 [14.2K]

Answer:

x=0.933333

Step-by-step explanation:

First you add 6 to both sides of the equation

15x - 6 + 6 = 8 +6

That gives you 15x = 14

Then you divide 15 on both sides of the equation

That gives you x = 14/15 = 0.93333

xz_007 [3.2K]

Answer:

(x, y ) → (x + 5, y - 3 )

Step-by-step explanation:

5 units right means add 5 to the x- coordinate

3 units down means subtract 3 from the y- coordinate

the translation rule is

(x, y ) → (x + 5, y - 3 )

James works at a grocery store. He makes $6.20 per hour and works 30 hours each week. How much money will james make in a 4-week
lara31 [8.8K]

It is a very simple question to answer.

Obviously first we can calculate his weekly earnings and then multiply them by 4 to calculate his total earnings over the course of 4 year period.

So as he makes 6.2$ an hour. He will make 6.2 * 30 = 186 $ a week as that is the number of hours he works in a week.

Now we can multiply this by 4 to calculate his over all earnings. So 186 * 4 = 744.

The sum of two numbers is 18. One number is 2 more that for times the other. Find the numbers.
seropon [69]
Hi there!

Let the first number be represented by X.
The second number (which is 2 more than four times the other), can be represented by 4X + 2.

We can now find the sum of this expression.
X + 4X + 2

Collect terms
5X + 2

The sum of the numbers is 18. Therefore we can set up the following equation.
5X + 2 = 18

Subtract 2.
5X = 16

Divide both sides by 5.
X = 16/5 = 3 1/5.

Therefore, the first number is 3 1/5. To find the second number we must plug in X = 3 1/5 into the expression 4X + 2

4 * (3 1/5) + 2 = 12 4/5 + 2 = 14 4/5
The two numbers are
3 \frac{1}{5}  \:  \: and \:  \: 14 \frac{4}{5}

~ Hope this helps you!

A parabola has an x-intercept of -1, a y-intercept of -3, and a minimum of -4 at x = 1.
torisob [31]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

y=a(x-h)^{2}+k

where

a is a coefficient

(h,k) is the vertex

In this problem we have

(h,k)=(1,-4)

substitute

y=a(x-1)^{2}-4

we have

An x-intercept of (-1,0)

substitute and solve for a

0=a(-1-1)^{2}-4

0=4a-4

4a=4

a=1

The equation is

y=(x-1)^{2}-4

<u><em>Verify the y-intercept</em></u>

For x=0

y=(0-1)^{2}-4

y=-3

The y-intercept is the point (0,-3) -----> is correct

using a graphing tool

see the attached figure
