< ADF measures 2x degrees and < FDC measures x + 12 degrees. What is the measure

gtnhenbr [62]

Answer:

<h2>Angle ADF is equal to 52° and angle FDC is equal to 38°.</h2>

Step-by-step explanation:

In the image attaches, you can observe that angles ADF and FDC are complementary angles, because they sum 90°.

$\angle ADF + \angle FDC = 90\°$

And we know that

$\angle ADF=2x\\\angle FDC = x+12$

Replacing these expressions, we have

$2x+x+12=90\°\\3x=90\° - 12\°\\x=\frac{78}{3}\\ x=26$

Then, we replace this value in each expression to find both angles measures.

$\angle ADF= 2(26)=52\°\\\angle FDC = 26+12=38\°$

Therefore, angle ADF is equal to 52° and angle FDC is equal to 38°.

Kamal spent 40% of his income. He

Arte-miy333 [17]

Answer:

Step-by-step explanation:

Percentages

It's given Kamal spent 40% of his income. With the remaining 60%, he deposited Rs. 400 in a bank and still has Rs. 500 left.

This means Rs. 400 + Rs. 500= Rs. 900 is 60% if his income.

The 100% of his income is calculated as a percent proportion:

If 60% is Rs. 900, then 100% is:

$\displaystyle \frac{900}{60}*100=1500$

Thus, Kamal's income is Rs. 1500. Correct choice: (c) Rs. 1500

Express p as the subject of the formula<br>q= p² - r ÷ t

Rudik [331]

Answer:

p = $\sqrt{q +\frac{r}{t} }$

Step-by-step explanation:

q= $p^{2}$ - r÷ t using BODMAS

q = $p^{2}$ - (r/t)

q + r/t = $p^{2}$

p= $\sqrt{q+\frac{r}{t} }$

The distance, y, in centimeters, of an ant from a hole in the tree for a certain amount of time, x, in seconds, is shown in the

Alenkasestr [34]

Answer:

The graph is non-linear as it is not a continuous straight line (with only one slope).

<u>Increasing</u>: the y-value increases as the x-value increases

<u>Constant</u>: the y-value stays the same as the x-value changes

<u>Decreasing</u>: the y-value decreases as the x-value increases

Therefore,

Increasing segment: Between 0 and 2 seconds
Constant segment: Between 2 and 3 seconds
Decreasing segment: Between 3 and 5 seconds

For the first 2 seconds, the ant moves 6 cm from a hole in the tree at a steady speed of 3 cm per second. For the next second, the ant is at rest then turns around. For the next 2 seconds, the ant moves 6 cm back to the hole at a steady speed of 3 cm per second. The ant then stops.
