Line segment XY is tangent to circle Z at point U. If the measure of is 84°, what is the measure of ? 42° 84° 96° 168°

Andreas93 [3]

Answer:

The measure of angle YUV is equal to $m$

Step-by-step explanation:

see the attached figure to better understand the problem

we have that

$arc\ UV=84\°$ -----> given problem

$m$ ------> by central angle

we know that

The triangle UZV is an isosceles triangle

because

$ZU=ZV=radius$

$m$ -----> bases angle of the isosceles triangle

Remember that

The sum of the internal angles of a triangle is equal to $180\°$

$m$

$2m$

substitute and solve for m<ZUV

$2m$

$m$

$m$ ------> by complementary angles

solve for m<YUZ

$48\°+m$

$m$

The sides of a rectangle are in the ratio 2:5. The perimeter of the rectangle is 70 cm. What is the width of the rectangle?

EleoNora [17]

Width = 10cm

Length = 25cm

<u>Explanation: </u>

Given, width:length = 2:5

Let width = 2x ,

So, length = 5x

Perimeter of rectangle = 2x(length + width)

According to the question,

$70cm = 2X(5x + 2x)\\70cm = 2X(7x)\\35cm = 7x\\x = 5cm$

Hence,

Width = 10cm

Length = 25cm

Maria ran 17 miles at an average speed of 5 miles per hour.

mel-nik [20]

I think this is what it's asking for...

a) 17 is the total amount ran
5 is the number of miles
x is the hours (which is unknown)
you have to find x. the problem says that there are 5 miles per hour so your x would go with your 5. the 17 stays on the opposite side of the =
17=5x

b) to find the amount of time (x) just solve for x
17=5x is your equation
you now have to isolate the x (do this by dividing 5 on both sides of the equation)
5/x= x alone
17/5=3.4
3.4=x
* remember that x is hours in this problem, so round if you need too

before school began mrs. weeks bought a total of 86 balls us the information below to help you write a numerical expression

STALIN [3.7K]

For this case we have that the total of the balls is 86. We know there are 8 footballs then:

Basketball: Two more than twice the number of footballs are basketballs, that is:

$2 + 2 (8) = 2 + 16 = 18$

There are 18 Basketballs.

Baseballs: Four less than 5 times the number of footballs are baseballs, that is:

$5 (8) -4 = 40-4 = 36$

There are 36 Baseballs.

Softballs: Six more than half of baseballs are softballs. That is to say:

$6+ \frac {36} {2} = 6 + 18 = 24$

There are 24 Softballs

If we add we must get 86.

$8 + 18 + 36 + 24 = 86$

ANswer:

There are 8 Footballs

There are 18 Basketballs.

There are 36 Baseballs.

There are 24 Softballs

Dominica $2000 for 3years at an interest rate of 7% how much interest did she earn on her money?

Vinvika [58]

Answer:

$420

Step-by-step explanation:

The formula for simple interest is i = prt, where p is the principal, r is the annual interest rate expressed as a decimal fraction, and t is the number of years.

Here p = $2,000, r = 0.07 and t = 3 yr, and so

i = ($2,000)(0.07)(3) = $420 was the amount of interest earned.
