What is m∠BAC.
............
Answer:
37 degrees
Step-by-step explanation:
1. m∠CBA = 71+45 = 116 degrees
2. m∠CBA = m∠CDA because of the quadrilateral property of opposite sides.
3. m∠CBA + m∠CDA = 2*116 = 232.
4. Total angle measure of a quadrilateral is 360 degrees, so m∠BAD + m∠BCD = 360-232 = 128 degrees.
5. m∠BAD = m∠BCD = 128/2 = 64 degrees
6. m∠BAC = m∠BAD - m∠CAD = 64 - 27 = 37 degrees

10.In Star School, the ratio of students who bring
lunch from home to those who buy it at tuck-shop
is 11:3. If 87 buy their lunch, how many students
are there at the school?
Answer:
There are 406 students in the school
Step-by-step explanation:
Let the number of students in the school be x
The total ratio is 11 + 3 = 14
The ratio that buys lunch is represented by 3
So, we have it that;
3/14 * x = 87
3x = (14 * 87)
x = (14 * 87)/3
x = 406
2 and 1/3 + 2 and 2/3 = ?
Answer:
5
Step-by-step explanation:
When adding fractions, all you are doing is adding the whole numbers first, 2+2, and then putting that aside. So with 4 on the side, we will then add our fractions. We will line them up and add the numerators and leave the denominator the same. If the numerator is higher than the denominator, we create a whole and subtract the denominator until we are with a smaller numerator. However many times we subtracted this would add a whole number. However, we do not have to do this so we will add 1 and 2 to equal 3. This means we have 3/3 or one whole so we will add 1 to the 4 we had earlier to get 5. Hope this helps :D

Step-by-step explanation:
Tina brought $37.75 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1 6 as much as the sketchbook, and the sketchbook cost 3 4 the cost of the paint set. Tina had $4.00 left over after buying these items.
Answer:
18.75=p
s=14.06
b=2.34
Step-by-step explanation:
37.75=b+s+p
-4
33.75=b+s+p
s=3/4p
b=1/6s
33.75=1/6(3/4p)+3/4p+p
33.75=3/20p+3/4p+p
(33.75=18/20p+p)20
675=18p+p)/18
37.50=2p)/2
18.75=p
s=3/4p
3/4(18.75)
s=14.06
b=1/6s
1/6(14.06)
b=2.34
37.75-4=18.75+14.06+2.34=35.15
im missing 50 cents somewhere its wrong but close i think sorry
The cost of a brush, a sketchbook and a paint set given the total amount with Tina is $2.25, $13.5 and $18 respectively.
How to write and solve equation?Total = $37.75
Amount left = $4.00
let
paint = pb = 1/6ss = 3/4p37.75 = p + b + s + 4
37.75 - 4 = p + 1/6s + 3/4p
33.75 = 1/6s + 1 3/4p
33.75 = 1/6(3/4p) + 1 3/4p
33.75 = 3/24p + 7/4p
33.75 = 3+42 / 24p
33.75 = 45/24p
p = 33.75 ÷ 45/24
= 33.75 × 24/45
= 810/45
p = $18
substitute into
s = 3/4p
= 3/4 × 18
= 54/4
s = $13.5
b = 1/6s
b = 1/6 × 13.5
b = 13.5/6
b = $2.25

Please help I’ll give brainliest!
Please answer this for me.
Answer:
(x + 5)**2 + (y + 2)**2 = 25
Step-by-step explanation:
We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. The graph shows the center at (-5, -2), and the radius of 5. So plugging this in
(x - -5)**2 + (y - - 2)**2 = 5**2
(x + 5)**2 + (y + 2)**2 = 25

When you subtract x2 + 2xy + y2 from 2x2 + 6xy - 3y2, what is the result?
Answer:
x2 + 4xy - 4y2
Step-by-step explanation:
You have to subtract the values with like terms, so you´d have to take x2 from 2x2. You can´t take away x2 from 6xy because they are different terms, and it wouldn´t be compatible.
