please help, would be greatful :)

Answers

Answer:

1. a = 21°

2. b = 70°

3. c = 89°

Step-by-step explanation:

1. Determination of the value of a.

a = 21° (vertically opposite angles are equal)

2. Determination of the value of b.

From the question given above,

110 + b = 180 (sum of angles on a straight line)

Collect like terms

b = 180 – 110

b = 70°

3. Determination of the value of c.

a + b + c = 180 (sum of angles in a triangle)

a = 21°

b = 70°

c =?

21 + 70 + c = 180

91 + c = 180

Collect like terms

c = 180 – 91

c = 89°

What is the measure of angle ABE?

Answers

You find the measure of angle BEC, by adding angle B and angle C which is 43+90, and then subtract that from 180 and get 180-(43+90). Then you take the measure of angle BEC (which is the same as AEB), take AEB and A which is 90 degrees and add those together. Then you take that and subtract it from 180, which is 180-(AEB+90)

2)what is the ratio of 400m to 1.5km​

Answers

Answer:

4km/1.5km

Step-by-step explanation:

hope that helps :)

Ratio of 400m to 1.5km​ is 400/1500 or 400:1500

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Here the given quantities are 400m and 1.5km

The quantities are with different unit

We convert them into same unit

We know that one kilometre=1000 metre

One kilometre equal to thousand metres.

Let us convert 1.5 km to metre by multiplying 1.5 with 1000

1.5×1000=1500

The ratio of 400m to 1.5km​ is 400/1500 or 400:1500

Hence  ratio of 400m to 1.5km​ is 400/1500 or 400:1500

Solve the following two equations. Show all of your

work!
Equation #1: 7x =
21.25
Equation #2: 3(y - 2) = 12

Answers

Equation 1:
7x = 21.25 or
21.25/7 = x
21.25/7 = 3.03571429
so x = 3.03(just round to whatever place u need).

Equation 2:
3(y - 2) = 12 or
3(x)=12
x=4
so y - 2 has to equal 4
and 6-2 = 4 therefore
y = 6.

Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. She scored a total of 24 baskets for both games. How many baskets did Mia score last Saturday?

Please show me how to do it and the answer. :)

Answers

Answer:

Mia scored 6 baskets Last Saturday.

Step-by-step explanation:

Let:

Mia made score of baskets on Last Saturday = x

Mia made score of baskets yesterday = 3x (Mia made three times as many baskets in yesterday’s basketball game as she did last Saturday. three times means multiply 3 with score of Last Saturday baskets, i.e. x)

Total score of baskets = 24

We need to find How many baskets did Mia score last Saturday?

We can write:

Total Score = Score on Last Saturday + Score yesterday

[tex]24=x+3x[/tex]

Solving this equation we can find value of x:

[tex]24=x+3x\\24=4x\\=>4x=24\\x=\frac{24}{4}\\x=6[/tex]

So, we get value of x = 6

Mia made score of baskets on Last Saturday = x = 6

Mia scored 6 baskets Last Saturday.
