What is the surface area of this design? A.76in2 B.280in2 C.360in2 D.392in2

Phantasy [73]

Answer:

There are 8 faces on the figure.

There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 = 152.

Then, there is another side that equals 4 x 4 which is 24.

Another side equals 4 x 6 which is 24.

Another one equals 6 x 6 which is 36.

Another side equals 6 x 6 which also equals 36.

Another side equals 10 x 6 which is 60.

The last side is 10 x 6 which equals 60.

Which should add up to 392 in.

A ramp leading into a building makes a 15° angle with the ground. The end of the ramp is 10 feet from the base of the building.

Paul [167]

Answer:

10.4feet

Step-by-step explanation:

The set up wil form a right triangle

Length of the ramp is the hypotenuse

The length of the end of the ramp from the base= 10 feet (adjacent)

Angle of elevation = 15 degrees

Required

Length of the ramp

Using SOH CAH TOA

Cos theta = adj/hyp

cos 15 = 10/L

L = 10/cos15

L = 10/0.9659

L = 10.35

L ≈ 10.4 feet

Hence the length of the ramp is 10.4feet

Your classmate says that the solutions to the given inequality are x > -2. Look carefully at the work. Should your friend hav

LuckyWell [14K]

Answer:

x < -2 (No, he shouldn't have reversed the inequality symbol).

Step-by-step explanation:

Given the algebraic expression;

19 - 2(1 - x) < 13

Opening up the bracket, we have;

19 + (-2*1) + (-2*-x) < 13

19 + (-2) + (2x) < 13

19 - 2 + 2x < 13

17 + 2x < 13

Rearranging the equation, we have;

2x < 13 - 17

2x < -4

Dividing both sides by 2, we have;

x < -2

Hence, your friend shouldn't have reversed the inequality symbol (sign).

Note: you should only flip the inequality symbol (sign) when you're dividing by a negative number such as -2.

For example, if we had re-arranged the equation as;

17 - 13 < -2x

4 < -2x

Dividing both sides by -2, we have;

4 > x

Abc is bisected by bd for what value of x will dx= day be true?

Reil [10]

Answer:

$x=3\\$

Step-by-step explanation:

Note that because BD is an angle bisector, then angle XBD and angle DXY are equal. Also note that BYD and BXD are equal because they are both right angles. Also, by the transaitive property, BD = BD. Therefore, it can be concluded that BXD is congruent to BYD.

Therefore, we must solve $5x+4=19 \Longrightarrow 5x = 15 \Longrightarrow x=3$ .
