Angle UTV is basically given: it's 138°.

Moreover, since UTV is isosceles, the other two angles have the same measure x. We thus have

$138+x+x=180 \iff 2x=42 \iff x=21$

So, TUV is 21°, and VUW is complementary, so it must be 69° so that they sum up to 90°

A coed little league team had 18 players . Even though it was raining half the girls and one third of the boys showed up for the

Genrish500 [490]

Answer:

The number of Girls players in the Team of 18 players is 6 .

Step-by-step explanation:

Given as :

The total number of player including boys and girls = 18

And $\frac{1}{2}$ times girls player + $\frac{1}{3}$ times boys player = 7

Let The number of boys player = B

The number of girls player = G

So, According to question

G + B = 18 ...1

$\frac{1}{2}$ × G + $\frac{1}{3}$ × B= 7

or, $\frac{G}{2}$ + $\frac{B}{3}$ = 7 ...2

or, Put the value of B from eq 1

or, $\frac{G}{2}$ + $\frac{18 - G}{3}$ = 7

Or, $\frac{G}{2}$ - $\frac{G}{3}$ + 6 = 7

or, $\frac{3G - 2G}{6}$ = 7 - 6

Or, $\frac{G}{6}$ = 1

∴ G = 1 × 6 = 6

Hence The number of Girls players in the Team of 18 players is 6 . Answer

10. A circle has an arc with measure 80° and length 887. What is the<br> diameter of the circle?

zaharov [31]

The diameter of the whole circle is 2*pi*radius . The arc length is then 80/360*pi*radius*=88*pi
radius=88*180/80
=44*180/40
=22*180/20
=11*180/10
=11*18
=(10+1)*18
=198
The diameter is 2*198=(200-2)=400-4=396

SO BASICALLY THE ANSWER IS 396

Jamal borrowed $15 600 for 6 years from a bank. The annual simple interest rate for the first 3 years is 1.6%. From then onward,

r-ruslan [8.4K]

Answer:

the interest owed is 1684.8

Step-by-step explanation:

Formula for simple interest =

I = Prt, where P is amount borrowed, r for interest rate and t for time.

Since the first three years is 1.6% interest we can write:

I = 15600 x 0.016 x 3

= 748.8

Then for the following 3 years the interest rate is 2%:

I = 15600 x 0.02 x 3

= 936

Adding the values gives us 1684.8
