Answer:

The top angle of the triangle is, X = 68°.

Step-by-step explanation:

Let there is a triangle named PQR with bottom corner angles ∠ P and ∠ Q and the ∠ R is the angle at the top.

Now, given that ∠ P = 31° and ∠ Q = 81° and we have to find out ∠ R i.e. X.

In Δ PQR, we know, ∠ P + ∠ Q + ∠ R = 180°

⇒ 31° + 81° + X = 180°

⇒ X = 68°

Therefore, the top angle of the triangle is 68°. (Answer)

wolverine [178]

Answer:

$\$1,616.60$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=5\ years\\ P=\$1,500\\ r=1.5\%=1.5/100=0.015\\n=4$

substitute in the formula above

$A=1,500(1+\frac{0.015}{4})^{4*5}$

$A=1,500(1.00375)^{20}$

$A=\$1,616.60$

A rectangular lawn is 24 feet wide by 32 feet long. A sidewalk will be built along the inside edges of all four sides. The remai

levacccp [35]

So the original lawn has an area
24 × 32 = 768 the new lawn will have area 425
this means the area of the sidewalk will be 768-425=343
now the sidewalk is a certain width of we draw it out and label it x we see the lawn has an area of
$(32 - 2x)(24 - 2x) = 425 \\ 768 - 64x - 48x + 4 {x}^{2} = 425 \\ 4 {x}^{2} - 112x + 343 = 0$
use the quadratic formula to solve. then you will know how wide the sidewalk is. I will attach picture

the probability of a chance event is close to 0. which statement about the event is true/ (A) the event is likely to occur (B) t

Snezhnost [94]

The probability is always between 0 and 1 inclusive. If the probability is 0, the event is definitely not going to occur, and if the probability is 1, the event will definitely occur.

Now, if the probability of a chance event is close to 0, then the event is unlikely to occur.
