Answer:

Step-by-step explanation:

Square A:

Area = 225 square feet

side *side = 225

Side =√225

$=\sqrt{15*15}$

Side of square A = 15 ft

Square B:

Area = 400 square feet

Side =√400

= $\sqrt{20*20}$

Side of square B = 20 ft

Use Pythagorean theorem for finding the side of Square C.

Side of square A is the altitude ; side of square B is the base and side of square C will be the hypotenuse

hypotenuse² = base² + altitude²

= 15² + 20²

= 225 + 400

= 625

hypotenuse = $\sqrt{625} =\sqrt{25*25}$ = 25 ft

Area of square C = 625 square ft

In short,

Area of square C = area of square B + area of square A

= 400 + 225

= 625 square ft

At 3:30 p.m., you have 15 megabytes of a movie. At 3:45 p.m., you have 75 megabytes. What is the download rate in megabytes per

snow_lady [41]

Because the time moved up by 15 minutes, we would already know that it would be (blank) megabytes per 15 minutes

75 megabytes - 15 megabytes = 60

this would mean 60 megabytes are downloaded per 15 minutes

simplified by 15, our answer would be 4 megabytes downloaded per minute

both of the answers above would be acceptable :)

Which inequality will have a dashed boundary line with a shaded area above its graph? 7x − y ≤ 3 x − y ≤ 4 2x − 9y > 2 4x + 7

alexdok [17]

Above the graph

look at them

7x-y <span><</span>3
x-y<span><</span>4
2x-9y>2
4x+7y>3

dashed boundary line means it does't include htat means taat the symbol is < or >

cross out first 2

one way is to graph the lines as equations and shade accordingly

2x-9y>2
y<2/9x+2/9
shade on bottom

4x+7y>3
y>-7/4x+3/9
shade on top

aswer is 4x+7y>3

Select the functions that have a value of -1. sin180° cos180° tan180° csc180° sec180° cot180°

kupik [55]

We have to break each degree in terms of 90

A) $sin180^\circ=sin(90\times2+0)$

Which is in third quadrant, therefore sine is negative hence

$sin(90\times2+0)= -sin0 ^\circ = 0$

B) $cos180^\circ =cos(90\times2+0)$

Which is in third quadrant, therefore cosine is negative hence

$cos(90\times2+0)= -cos0^\circ = -1$

C) $tan180^\circ=tan(90\times2+0)$

Which is in third quadrant, therefore tangent is positive hence

$tan(90\times2+0)= tan0^\circ = 0$

D) $csc180^\circ=csc(90\times2+0)$

Which is in third quadrant, therefore cosec is negative hence

$cosec(90\times2+0)= -csc0^\circ =$ not defined

E) $sec180^\circ=sec(90\times2+0)$

Which is in third quadrant, therefore secant is negative hence

$sec(90\times2+0)= -sec0^\circ = -1$

F) $cot180^\circ=cot(90\times2+0)$

Which is in third quadrant, therefore tangent is positive hence

$cot(90\times2+0)= cot0^\circ =$ not defined

Hence only $cos 180^\circ$ and

$sec180^\circ$ have value -1

Hope this will help

A certain component of an electronic device has a probability of 0.1 of failing. If there are 6 such components in a circuit, wh

blondinia [14]

The probability of one failing is 0.1
The probability of two failing is 0.1 x 0.1 = 0.01
The probability if three failing is 0.1 x 0.1 x 0.1 = 0.001
etc
The probability of all six failing is 0.1 x 0.1 x 0.1 x 0.1 x 0.1 x 0.1 = 0.000001
