Can anyone help me with this?

Answer:

Below.

Step-by-step explanation:

7) c^2 = a^2 + b^2

15^2 = 11^2 + b^2

b^2 = 225 - 121 = 104

b = √104

= √4√26

= 2√26.m

8). 4^2 = a^2 + (√6)^2

a^2 = 16 - 6

a^2 = 10

a = √10.

At a track meet, Samma finished the 200-meter race in 25.98 seconds. Tom finished the 100-meter race in 12.54 seconds. Which run

ANEK [815]

Time = distance / speed

Samma : 200/25.98 = 7.70 meters per second
Tom : 100 / 12.54 = 7.97 meters per second

so the faster runner is Tom

IAS question - ❓❓❓❓❓❓A man starts frm his house with some money to visit four temples.1. As soon as he enters temple 1 his money

Natali5045456 [20]

Answer:

Rs 93.75

Step-by-step explanation:

Solution:

A man starts from his house with some money to visit four temples.

1. As soon as he enters temple 1 his money gets doubled.

Let he had money at first = $x$

After enter the 1st temple his money = $2x$

He donated = Rs 100

Money left after donation at 1st temple = $2x-100$

2. At temple 2 again his money is doubled and he donates Rs 100

He had at 2nd temple = $2(2x-100) =4x-200$

Donated = Rs 100

Money left after donation at 2nd temple = $4x-200-100=4x-300$

3. His money is doubled again at temple 3 and he donates Rs 100.

He had at 3rd temple = $2(4x-300)=8x-600$

Donated = Rs 100

Money left after donation at 3rd temple = $8x-600-100=8x-700$

4. At temple 4 again his money gets doubled. He donates 100 rs. again and returns home empty handed.

He had at 4th temple = $2(8x-700)= 16x-1400$

Donated = Rs 100

Money left after donation at 4th temple = $16x-1400-100 = 16x-1500$

As he returned empty hand or with zero money, equation will be:-

$16x-1500=0\\ \\ Adding\ both\ sides\ by\ 1500\\ \\ 16x=1500\\ \\ Dividing\ both\ sides\ by\ 16\\ \\ x=Rs \ 93.75$

Thus, he had Rs 93.75 when he started from his house.

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary.

Rama09 [41]

Check the picture below.

now, we have a triangle with all three sides, thus we can use Heron's Area Formula on the triangle.

$\bf \qquad \textit{Heron's area formula} \\\\ A=\sqrt{s(s-a)(s-b)(s-c)}\qquad \begin{cases} s=\frac{a+b+c}{2}\\[-0.5em] \hrulefill\\ a=10\\ b=26.695\\ c=22\\ s=29.3475 \end{cases} \\\\\\ A=\sqrt{29.3475(29.3475-10)(29.3475-26.695)(29.3475-22)} \\\\\\ A=\sqrt{29.3475(19.3475)(2.6525)(7.3475)}\implies A\approx \sqrt{11066.007} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill A\approx 105.195~\hfill$

Find the value of x. Part 2c

tia_tia [17]

<h3>Answer: x = -12</h3>

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

Work Shown:

Let's label angle 2 as y, so y = x+132.

Also, let's add another variable z. We'll make z equal to the angle adjacent and supplementary to angle y. So y+z = 180

Solve for z to get

z = 180-y

z = 180-(x+132)

z = 180-x-132

z = 48-x

This angle z is added to the 90 degree angle to get the measure of the exterior angle 150 degrees. This is through the remote interior angle theorem.

So,

z+90 = 150

48-x+90 = 150

138-x = 150

-x = 150-138

-x = 12

x = -12
