Answer:
B. 132°Step-by-step explanation:
Find the measure of arc BD
m∠A = 1/2(arc BC - arc BD) 2*36° = 150° - arc BD arc BD = 150° - 72° = 78°Find the measure of arc DC
arc BD + arc BC + arc DC = 360°arc DC = 360° - (150° + 78°) = 360° - 228° = 132°Correct choice is B
Warren made 5 pans of brownies. He will slice the brownies into pieces, and each piece will be 1/10 of the size of a pan. How many slices of brownies will Warren create? a. 10 b. 25 :c. 50. d. 100
Answer:
c
Step-by-step explanation:
If a piece is equal to 1/10 of a pan , a pan would make 10 brownies
5 pans would make , 10 x 5 = 50 brownies
Answer: c
Step-by-step explanation: each pan is 10 slices so if you multiply that with how many pans you have which is 5 and 5 x 10 = 50
The first two terms of a sequence are a1 =4 and a2= -2. Let a3 be the third term when the sequence is arithmetic and let b3 be the third term when the sequence is geometric. Find a3+b3
Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7
Please help me asap. I need an answer and full explanation. 1st person to complete that gets Brainliest. Question: Amelia likes to collect pokemon cards. She currently has 34 water cards and 29 fire cards. How many more fire cards does she need to collect so her ratio of the number of water cards to fire cards is 2:3?
Thanks and stay perfect.
Answer:
22 cards
Step-by-step explanation:
Set up a ratio.
[tex]\frac{34}{29+x} =\frac{2}{3}[/tex]
[tex]58+2x=102[/tex]
[tex]2x=44[/tex]
[tex]x=22[/tex]
Check: Add 22 to 39. 22+29=51
34/51 = 2/3
Have a great day

Step-by-step explanation:
To figure out if a set of angles are in a triangle, make sure they add up to 180
F) 58,70,62 58 + 70 + 62 = 190 This option is incorrect
G) 41,68,71 41 + 68 + 71 = 180 This option is correct
H) 68,60,52 68 + 60 + 52 = 180 This option is correct
J) 73,42,65 73 + 42 + 65 = 180 This option is correct
Since option F did not equal 180, F is the answer.

y = x - 16
5y = 2x - 56
Step 2: Solve for x
Substitute in y: 5(x - 16) = 2x - 56Distribute 5: 5x - 80 = 2x - 56[Subtraction Property of Equality] Subtract 2x on both sides: 3x - 80 = -56[Addition Property of Equality] Add 80 on both sides: 3x = 24[Division Property of Equality] Divide 3 on both sides: x = 8Step 3: Solve for y

Answer:
27.5 /100 are running for a cause
Step-by-step explanation:
We know that 220/800 are running for a cause
Divide the top and bottom by 8 to get the fraction out of 100
220 /8 =27.5
800/8 = 100
27.5 /100 are running for a cause
200 children went on holiday. 18% of the children went to Wales. 27% of the children went to Scotland. How many more children went to Scotland than went to Wales?
Answer:
18 children
Step-by-step explanation:
The computation of the more children went to scotland is as follows:
Given that
There is 200 children
out of which 18% went to wales i.e. = 200 × 18% = 36
And, 27% went to scotland i.e. = 200 × 27% = 54
So, the more children went to scotland is
= 54 - 36
= 18 children
