You can use the vertical angles theorem to find the value of x.

2x+84=5x
84=3x
x=28
Now, since <TSV and >PSV are linear pairs, you can add PSV and TSV. To do this, you have to find the value of PSV.
PSV=5x
x=28, so PSV = 5(28)
PSV=140°.
Now, find TSV.
180°-140°=40°

m<TSV=40°, or B.

The formula for the size of a file that was downloaded over time t and at an average rate r is r.t.

lakkis [162]

Answer:

The size of file downloaded is <em>88 megabytes.</em>

Step-by-step explanation:

Given that:

Average rate of downloading the file = $r$

Time taken to download = $t$

Formula for the size of file downloaded = $r.t$

Rate of downloading, $r = 800\ kilobytes/sec$

Time taken, $t$ = 110 seconds

To find:

Size of file downloaded in megabytes = ?

Solution:

First of all, let us apply the given formula to find the size of file downloaded:

Size of file downloaded = $r.t$

Size of file downloaded = 800 kilobytes seconds $\times$ 110 seconds =

<em>88000 kilobytes</em>.

Now, let us convert the unit kilobytes to megabytes to find the answer.

<em>Conversion formula:</em>

1000 kilobytes = 1 megabyte

Let us use unitary method to find the number of megabytes in 88000 kilobytes.

1 kilobytes = $\frac{1}{1000}$ megabytes

88000 kilobytes = $\frac{1}{1000} \times$ 88000 megabytes

$\Rightarrow$ <em>88 megabytes.</em>

Therefore, the size of file downloaded is <em>88 megabytes.</em>

Brittany's car gets 31 miles per gallon. Brittany's car used 24 gallons of gas on a round trip to see the ocean. How far away fr

shutvik [7]

Answer:

372 miles

Step-by-step explanation:

The appropriate relation is ...

miles = (miles/gallon) × gallons

distance = (31 mi/gal)×(24 gal) = 744 mi

Brittany drove 744 miles to see the ocean. Since this was her round trip distance, the one-way distance is ...

744 mi/2 = 372 miles

A necklace contains twenty-four spherical beads of silver, each having a radius of 0.5cm. The beads are to be coated, and the co

Inessa [10]

Answer:

$153

Step-by-step explanation:

To find the total cost, we have to calculate the area of one bead, then all of them:

Area of one bead = pi x r^2 = 3.14 x 0.5^2 = 3.14 x 0.25 = 0.765cm^2

Area of 20 beads = 0.765 x 20 = 15.3cm^2

Now, we are able to calculate the ultimate cost of coating:

If the cost is $10 per cm^2, then we have to find how much it costs to coat 15.3 cm^2.

15.3 x 10 = $153.

Hope this helps
