Answer:

Area = 1/2 * Height * Length

Step-by-step explanation:

This equation is derived from the area of a square, as a the area of a square is

A = Base (or Length) times the Height. A triangle will always be the half of that equation. Getting the correct height and length depends on the type of triangle and what information is available to use, with SOH-CAH-TOA being a useful concept to remember if you don't have the necessary information.

A store owner spends 7x + 13 dollars on two orders of boxes of light bulbs, including shipping.

Alex Ar [27]

Answer:

$B = 4x + 8$

A box = $11

Step-by-step explanation:

Given

$Total = 7x + 13$

Represent the first order with A and the second with B.

So, we have:

$A = 3x + 5$

Solving (a): Find B.

To find B, we make use of:

$A + B = Total$

Make B the subject

$B = Total - A$

Substitute values for Total and A

$B = 7x + 13 - (3x + 5)$

Open bracket

$B = 7x + 13 - 3x - 5$

Collect Like Terms

$B = 7x - 3x + 13 - 5$

$B = 4x + 8$

Solving (b): Cost of a box of light bulb

This means that:

$Total = 90$

Substitute 7x + 13 for Total

$7x + 13 = 90$

Collect Like Terms

$7x = 90 - 13$

$7x = 77$

Make x the subject

$x = \frac{77}{7}$

$x = 11$

Use the PARTITIONING strategy to solve these, don’t give random answers and actually use the P strategy please! take your time a

Dimas [21]

When we are partitioning in division, we are dividing the number into its place values, and then applying the divisor to each of the values.

For example in the first problem, we have 642, which is also 600 + 40 + 2.

That means we'll have three division problems.

600 ÷ 2 = 300

40 ÷ 2 = 20

2 ÷ 2 = 1

Which means that 642 ÷ 2 = 300 + 20 + 1, or 321.

You can apply this format to the other two problems to find their answers.

If you do, you should get that 969 ÷ 3 = 323, and 844 ÷ 4 = 211.

Hope this helps!

Semmy [17]

Answer:

$sin \alpha = \frac{opposite}{hypotenuse} \\ sin \alpha = \frac{8}{17} \\ sin \alpha = 0.470588235294117 \\ \alpha = {sin}^{ - 1} (0.470588235294117) \\ \alpha = 28.07 \: degrees$
