For question 1, angle ABC and angle CBD combines to form angle ABD. Just saying, question 2 literally answers question 1.

For question 2, it's literally addition. So 40 + 25 = 65°.

For question 3, it's just subtraction. 70 - 45 = 25°.

Answers

Answer:

Step-by-step explanation:

4.

a)

P = 2width + 2length

8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length

length = 3x

b)

sides= 1/4 of 3x = 3x/4

perimeter of square = 4* side = 4*3x/4 = 3x

c)

x= 4

P rectangle =8x= 8*4= 32

P square = 3x = 3*4 = 12

32-12 = 20 cm greater is the P rectangle than P of square

d)

A rectangle = 2x*x = 2*4*4 = 32

A square =(3x/4)² = (3*4/4)² = 9

32-9 = 23 cm² greater is the A rectangle than A of square

A bag contains 5 yellow balls 3 red balls and 2 green balls. A ball is removed from the bag without looking, the colour recorded, and then returned the bag. A second ball is drawn and its colour is also recorded.

c) What would be the outcome of the 2 balls if it has a probability of 1/10?

Answers

Answer:

the two balls are yellow and green, in either order.

Step-by-step explanation:

P(Y) = 5/10 = 1/2

P(R) = 3/10

P(G) = 2/10

Since the only combination that makes a product of 1/10, so

P(Y)*P(G) = (5//10) * (2/10) = 10/100 = 1/10

So the two balls are yellow and green, in either order.

The balls of two are yellow and green,in either order.

pls help. what is the equation of the trendline?

Answers

Answer:

0

Step-by-step explanation:

for which m is the slope, b is the y-intercept, x is any x value and y is any y value. By looking at the equation of the trend line, you can determine the y-intercept. For example, if the equation of the trend line is y=2x+5, the y-intercept is 5. You would receive this same answer if you let x = 0.

What is the area of a circle with a diameter of 150 cm?

Answers

Answer:

5625π cm²

Step-by-step explanation:

Radius = 150 / 2 = 75 cm

Area = πr² = π(75)² = 5625π cm²

Answer: 17662.5 (I used 3.14 instead of the regular pi but if you need to use pi the answer would be 17671.4587)

Step-by-step explanation:

First, you grab the diameter then divide that by 2 (that gives you the radius of the circle) Then, multiple 75² * 3.14 (or pi) to give you the answer!

what is the value of k ?

Answers

Answer:

27-degrees

Step-by-step explanation:

these are vertical angles which are equal to each other *congruent

39 + k = 66 --> *subtract 39 from both sides*

k = 27

Answer:

27°

Step-by-step explanation:

Remember the angle opposite of another angle in two straight lines are equal

So 66=39+k

Then put k by itself by subtracting 39 from both sides

66-39=k

k=27°

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 1000 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run

Answers

Answer:

i think its 200 m

Step-by-step explanation:

because 20 times 1000 rotations is 20000 cm so when u convert it to meter it is 200 meter if it is km it is 0.2 km

Distance ran by Avi's pet hamster chubby is 6280 cm.

The diameter of hamster wheel = 20 cm
Now the circumference of hamster wheel is given by :-

where d ⇒ the diameter of the hamster wheel.

During one race, the number of rotations of the wheel = 100
Therefore, the distance run by chubby is given by :-
Distance ran by chubby is equal to the number of rotations of the wheel times Circumference of the wheel.
framing in equation form we get;

D⇒ Distance ran by Chubby.

Hello! answer: 105

Step-by-step explanation:

You can find the area separately then add it up so... 10 × 6 = 60 10 × 9 = 90 90 ÷ 2 = 45

60 + 45 = 105 therefore the area is 105

Answer:

105 square meters

Step-by-step explanation:

Area= a + b/2 • h

Area= 15 + 6/2 • 10

Area= 21/2 • 10

Area= 10.5 • 10

Area= 105

Hope this helps, good luck!
