Answer:

$Area\ of\ a\ trinagle = \frac{5}{12}x^2$ $or\ 0.42x^2$

Step-by-step explanation:

Given:

Height of the triangle $h = x$

Base of the triangle $b=\frac{5}{6}x$

We need to find the area of the triangle.

Solution:

Using given Formula:

$Area\ of\ a\ trinagle = \frac{1}{2}bh$

Where:

b = Base of the triangle.

h = Height of the triangle.

Substitute $h = x$ and $b=\frac{5}{6}x$ in equation in given formula.

$Area\ of\ a\ trinagle = \frac{1}{2}(\frac{5}{6})x\times x$

$Area\ of\ a\ trinagle = \frac{5}{12}x^2$

$Area\ of\ a\ trinagle =0.42x^2$

Therefore, Area of the triangle is $\frac{5}{12}x^2$ or $0.42x^2$ .

Pls help! Urgent! Brainliest promised!

mart [117]

Answer: choices B, C, D and E

B) triangle RSP is similar to triangle ZXY

C) triangle SRP is similar to triangle XZY

D) triangle PSR is similar to triangle YXZ

E) triangle RPS is similar to triangle ZYX

In short, the answers is nearly everything but the first and last answer choice

================================================

For the first triangle, angle S is 54 degrees. In the other triangle, angle X is also 54 degrees. This means that the two angles correspond as they are equal to one another. The answer will have the letters S and X show up in the same position, whether that position is the first, second or third place of the three letter sequence.

Choice A is not one of the answers. RPS ~ XYZ is false because of what I mentioned above. We see that S is shown last in RPS while X is shown first in XYZ. The letters S and X do not correspond together, so we can cross choice A off the list.

Choice B is one of the answers because we have R corresponding to Z (first letters of each sequence RSP and ZXY; both are 41 degrees) and we have S correspond to X, and we have P correspond to Y (both the same measure as well)

Choice C is another answer for similar reasons as choice B. The only difference is that R and S have swapped, so have X and Z. The order is important or else things wouldn't line up properly.

Choice D is another answer. Again we have the same correspondence of P to Y (both in the first slot), S to X (second slot), and R to Z (third slot). For each slot, the pair of angles are both the same measure.

Choice E is another answer. Similar reasons as before, just a different order.

Choice F is not one of the answers. We see that P and Z occupy the second slots, but they aren't congruent angles.

A married couple filing their federal income tax return jointly had a taxable

julia-pushkina [17]

Answer:

The income will they have left over after paying their federal income tax is $64,850.00.

Step-by-step explanation:

Given:

A married couple filing their federal income tax return jointly had a taxable

income of $76,300.

Now, to find according to the table the income will they left over after paying their federal income tax.

So, as given in table:

The tax of the taxable income over $67,900 but not over $1,37,050 is $9,350 plus 25% of the amount over $67,900.

As, the taxable income $76,300 falls in to the above conditions.

Now, to calculate the tax:

$9350+25\%\ of\(76300-67900)$

$=9350+25\%\ of\ 8400$

$=9350+\frac{25}{100} \times 8400$

$=9350+0.25\times 8400$

$=9350+2100$

$=11450.$

Thus, the tax = $11450.

Now, deducting the tax from the taxable income:

$76300-11450\\=64850$

So, the amount left = $64,850.

Therefore, the income will they have left over after paying their federal income tax is $64,850.00.

What is the next term in the geometric sequence? 7,14,28, __

aleksandr82 [10.1K]

We have to look for the pattern in the numbers, so we can figure out what the next term in the sequence is !

It looks like, each number is multiplied by 2!

7 × 2 = 14

14 × 2 = 28

So, what's next?

28 × 2 = ?

The next term in the geometric sequence is ... 56!

I hope I helped :)

three friends Run a 10 mile relay each person runs an equal amount what fraction of the relay does each person run

Anon25 [30]

Hey there!

Since there are 3 friends running an equal amount of this relay race, each will run 1/3 of the relay.

This is because 3 thirds make a whole, and each third is equal to the others, so if you add each distance ran by each of the friends, or simply multiply each portion by 3, you'd get 10 miles.

If you're also looking for how long each friend runs, which I know isn't in the question but I'll add it anyways, it is 3 1/3 miles. This can be found by dividing 10 into 3 equal parts.

Hope this helps!
