Maggie's brother is 5 years younger than three times her age. The sum of their ages is 43.
serious [3.7K]
Wouldn't she be 8 since 8x3 is 24 and 24-5 is 19 which equals to 43 if 24 and 19 are added together.

Area = 120 units squared <br> Base = 8 units <br> Length = ? (Include the units in your answer)
Vesnalui [34]

Answer:

15

Step-by-step explanation:

Okay, so we know that Base*Length=Area, so we just have to divide the area by the base, so the formula here is Area/Base=Length.

That would get us 120/8=Length,

and if we just divide 120 by 8 we get 15, so the length is 15

Secant TQ and tangent TR intersect at point T. Chord SR and chord PQ intersect at point V. Find the values of x and y. If necess
san4es73 [151]

Answer:

x=4, y=9.6

Step-by-step explanation:

Using Theorem of Intersecting Secant and Tangent

TP X TQ=TR^2

9(9+12+x)=15^2\\9(21+x)=225\\189+9x=225\\9x=225-189\\9x=36\\x=4

Next, we apply Theorem of Intersecting Chords

SV X VR=PV X VQ

5 X y = x X 12

Recall: x=4

5y=4 X 12

5y=48

y=48/5=9.6

Therefore: x=4, y=9.6
