Triangle HIJ is dilated by a scale factor of 5 to form triangle H'I'J'. Side I'J' measures 75. What is the measure of side IJ?

Answers

Answer 1

Answer:

15

Step-by-step explanation:

I'J' is IJ with the scale factor of 5.

so (IJ) × 5= (I'J)

(IJ) × 5= 75

75 ÷ 5= 15

I am so sorry i did the math wrong in my head, the answer is 15 not 16.

The figure below shows a shaded circular region inside a larger circle:
r3 inches
R5 inches
What is the probability that a point chosen inside the larger circle is not in the shaded region?
O 24%
O 36%
O 50%
O 64%

Answers

Answer:

Probability is 64%

Step-by-step explanation:

Given the smaller circle which is shaded whose radius is denoted by r and  the largest circle whose radius is denoted by R

                     r = 3 inches

                    R = 5 inches

Step 1 : To calculate the area of shaded region.

Area of circle =

⇒ Area =    

          =   square inches

Step 2 : To calculate the area of larger circle.

Area of circle =

⇒ Area =    

            =  square inches

Step 3 : Calculate the probability that a point chosen from shaded region

Probability = Area of shaded region/Area of larger circle.

                  =  /

                  =  

                  =  0.36 = 36%

Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.

Probability = 1 - 0.36

                  = 0.64 = 64%

Hence the probability is 64%

Step-by-step explanation:

36 times 16 is 576

that probably didn't answer the question tho

Answer:

a = 3

b and c = 144

Step-by-step explanation:

since vertical angles congruent

12a = 36

a = 3

A line is 180 degrees so 12a = 36

180-36 = b and c

since vertical angles are congruent

b and c = 144

If you look closely the triangle on the left could be moved to the space on the right of the shape.

Then, the edges would be 10 inches (top) and 5 inches (sides).

From there, you multiply 10 x 5 to get 50. If you want the square root, you do [tex]\sqrt{50}[/tex] which is how I got 7.071067812, or 7.1, which was rounded to the nearest tenth.

Mr. Johnson purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under twelve. How many tickets for children under twelve did Mr. Johnson purchase?

Answers

Answer:

15

Step-by-step explanation:

15a +10c=$225
a + c = 20
Rewrite the second equation so it has a value for c
c= 20 -a
Now using substitution method replace the c for the given value
15a + 10(20-a)=225
15a +200-10a=225
Combine like terms
5a +200=225
5a=25
a=5
So 5 adult tickets were bought and 15 children tickets

The area of a parallelogram is base x height. You multiply the base and height (represented as b and h) to get the area of the parallelogram.

In the first question, the base and height is already given to you so, 2x6=12.

12yd squared is the area for the first one.

Now lets do the second one. The base and height is also given to you so do, 6x4=24.

24m squared is the area of the second one.

The red Maserati traveled at a speed of 120km/h for 5 hours one day. The green Ford Pickup traveled at a speed of 74km/h for 6 hours the same day. Find the difference in the distance traveled by two vehicles.

Answers

Answer:

156km

Step-by-step explanation:

red Maserati

speed= 120km/h

Time= 5h

distance= speed × time( see the formula pic)

= 120km/h × 5h

=600 km

green Ford Pickup

speed= 74km/h

Time= 6h

distance= speed ×time

=74km/h ×6h

=444km

difference

600-444=156km

156Km Because the red Maserati would go vroom vroom
