a. The measure of ∠ ABD is 6.2 times greater than the measure of ∠ CBD. Find the measure of ∠ CBD.
b. ∠ FBE and ∠ EBD are congruent. Find the measure of ∠ FBE
Answers
Answer:
awnser B and fbe is 55
Step-by-step explanation:
the entire picture is 180 so cut in half there for 90 ok abfe is 90 so bigger section is always 55 and smaller is 35 ok
If the measure of ∠ABD is 6.2 times greater than the measure of ∠CBD=25° and if ∠ FBE and ∠ EBD are congruent then ∠ FBE =65°.
Given that the measure of ∠ ABD is 6.2 times greater than the measure of ∠ CBD and ∠ FBE and ∠ EBD are congruent.
We are required to find the measure of ∠ CBD and ∠ FBE.
∠ABD=6.2*∠CBD--------1
∠ABD+∠CBD=180°
6.2 ∠CBD+∠CBD=180 (From equation 1)
7.2 ∠CBD=180
∠CBD=180/7.2
∠CBD=25°
∠ABD=6.2*25
=155°
∠ABD=90+∠EBD
155=90+∠EBD
∠EBD=155-90
∠EBD=65°
Because ∠ FBE and ∠ EBD are congruent, ∠ FBE =65°.
Hence if the measure of ∠ABD is 6.2 times greater than the measure of ∠CBD=25° and if ∠ FBE and ∠ EBD are congruent then ∠ FBE =65°.

Is Figure B a scale copy of Figure A?
Answers
Yes, the Figure B is a scale copy of Figure A.
Given that are two figures we need to see if the Figure B a scale copy of Figure A or not.
To determine if Figure B is a scale copy of Figure A, we need to compare the two figures and check if they have the same shape but differ in size. A scale copy means that Figure B is an enlarged or reduced version of Figure A, but the proportions and shape of the two figures remain the same.
We see the side lengths of Figure A are: 6 units, 3 units, 3 units, 3 units, 6 units.
And that of Figure B are: 2 units, 1 unit, 1 unit, 1 unit, 2 units.
Taking the ratio = 6/2 = 3/1 = 3/1 = 3/1 = 6/2 = 3
So, it is clear that the side lengths are in equal proportion.
Hence the Figure B is a scale copy of Figure A.

Simplify -15- |-7.5|
Answers
Answer:
-22.5
Step-by-step explanation:
-15- |-7.5|
after taking the absolute value off, -7.5 would become positive 7.5. But then the negative outside the absolute value makes it negative again.
-15-7.5
=-22.5
The simplified expression -15 - |-7.5| is equal to -22.5.
To simplify the expression -15 - |-7.5|, we'll follow these steps:
Evaluate the absolute value: |-7.5|.
The absolute value of a number is its distance from zero on the number line. In this case, |-7.5| is equal to 7.5 because 7.5 units away from zero.
Substitute the absolute value into the expression:
-15 - 7.5.
Perform the subtraction:
-15 - 7.5 = -22.5.
Therefore, the simplified expression -15 - |-7.5| is equal to -22.5.

3n + 3(6) or 3xn + 3x6 (same thing)
3n+18
Finally, we can check the other 4 choices to double check.

The base of an isosceles triangle is three times as long as the side of a square. Each leg of the triangle is 1 inch more than twice a side of the square. Find the length of a leg of the triangle if the sum of perimeters is 46 inches.
Answers
9 inches
Step-by-step explanation:Let x be the length of the side of the square.
If the base of the triangle is 3 times as long as the side of the square, it is 3 times x, or 3x.
The same can be said for the legs, which is 1 inch more than twice the side of the square, so 2x + 1.
The triangle can therefore be thought to look like the triangle below.
The perimeter is therefore (2x+1) + (2x+1) + 3x, which is 7x + 2.
The sum of perimeters of both the square and triangle is 46.
The perimeter of the square is 4x, so the sum of perimeters is 4x + (7x+2), or 11x + 2.
11x + 2 = 46, so 11x = 44.
x is therefore 4
The leg is 2x + 1, so the leg is 8 + 1, so the length of the leg is 9 inches.

Answer:
9) 1/42

Step-by-step explanation:
The probability of the compound event is the product of the probabilities of the parts. Note that the first draw (without replacement) modifies the probability of associated with the second draw.
9.5 is one of 7 tiles. After drawing 5, 6 is one of 6 tiles.
P(5 then 6) = P(5) × P(6 | 5) = 1/7 × 1/6 = 1/42
10.There are 3 odd tiles among the 7. After drawing one of them, 20 is one of 6 tiles.
P(odd then 20) = P(odd) × P(20 | odd) = 3/7 × 1/6 = 3/42 = 1/14
_____
Alternatively, you can consider the number of permutations of 2 tiles out of 7. That is P(7, 2) = 7!/(7-2)! = 7·6 = 42. Then the trick is to count how many of them will be the sequence of interest.
5 then 6: Among the 42 ways 2 tiles can be drawn, there is only one that is the required sequence: P(5,6) = 1/42.
odd then 20: There are 3 odd numbers, so the possible sequences of interest are (5,20), (7,20), (9,20). That is, there are 3 of 42 sequential draws that match the criteria. P(odd,20) = 3/42 = 1/14.
9) 1/42
10) 1/14
