In triangle A B D , the measure of angle A is 10 degree less than the measure of angle B . The measure of angle D is 20 degree more than 2.5 half times the measure of angle B . Find the m angle A . (Leave in fraction form.)

m angle A equals
degree

Answers

Answer:

Measure of angle A is 27 7/9 degrees.

Step-by-step explanation:

Lets call measure of angle A is X-10

Lets call measure of angle B is X

Lets call measure of angle D is 2.5X+20

We know that the sum of triangles add up to 180 degrees

X+X-10+2.5X+20=180

X=37 7/9

So measure of angle A is 27 7/9 degrees.

a Toowoomba and Perth
b. Hobart
C.Sydney and new castle
D.bendigo

Answers

Answer:

A Toowoomba and Perth

Step-by-step explanation:

its A on e2020

The smallest portion that Ann can cut out of her plans to stay under budget is option A, Toowoomba and Perth, which has a total cost of $291.

To find the smallest portion that Ann can cut out of her plans, we need to calculate the total cost of all cities and see which one is the highest.

Total cost = $161 + $264 + $198 + $130 + $224 + $301 + $277 = $1,555

Since Ann only has $1,265 budgeted for this portion of her trip, she needs to cut out some cities to stay under budget.

Toowoomba and Perth = $161 + $130 = $291

Hobart = $301

Sydney and Newcastle = $224 + $198 = $422

Bendigo = $277

Thus, the correct option is A.

Samreen's brother is 8 years younger than three times her
age. The sum of their ages is 32.

Answers

Answer:
Samreen’s age is 10
Samreen’s brother’s age is 22

Explanation:
Let s be equal to Samreen’s age.
Let b be equal to Samreen’s brother’s age.

3s-8=b
s+b=32

Substitute the first equation into the second as b
s+b=32
s+(3s-8)=32
Open up the parentheses
s+3s-8=32
4s-8=32
Add 8 to both sides
4s-8+8=32+8
4s=40
Divide both sides by 4 to isolate s
4s/4=40/4
s=10

Therefore, Samreen’s age is 10.

To find Samreen’s brother’s age, we substitute 10 into either of our original equations and solve for b.

s+b=32
10+b=32
Subtract both sides by 10
10+b=32-10
b=22

Therefore, Samreen’s brother’s age is 22.

Which of the following correctly uses absolute value to show the distance between -60 and 13? (5 points)

l-60 – 13| = |-73| = 73 units

I-60 13 = |-73| = -73 units

l-60 + 13| = |-47| = 47 units

I-60 + 13| = |-47| = -47 units

Answers

Answer:

l-60 – 13| = |-73| = 73 units

Step-by-step explanation:

Required

Distance between -60 and 13

Using absolute values, distance is calculated as:

[tex]Distance = |Start - End|[/tex]

Where

[tex]Start = -60[/tex]

[tex]End = 13[/tex]

So, we have:

[tex]Distance = |-60 - 13|[/tex]

[tex]Distance = |-73|[/tex]

Take absolute value of -73

[tex]Distance = 73[/tex]

Hence, option A answers the question
