Three angles are not acute

so it is false

sergejj [24]2 years ago

3 0

Answer:

This is false

Step-by-step explanation:

If the interior angles are in the ratio 4:3:2:1, let "a" represent the last angle. Then, the other angles are 2a, 3a, and 4a. The sum of the angles in a quadrilateral is 360°. So, only two angles are acute not 3

What is the reflection in the x-axis & what’s the reflection in line y=x?

marishachu [46]

Answer:

a) (3, -4), (2, 4), (-5, -6)

b) (4, 3), (-4, 2), (6, -5)

Step-by-step explanation:

a) Reflection in the x-axis negates the y-coordinate:

(x, y) ⇒ (x, -y)

(3, 4) ⇒ (3, -4)

(2, -4) ⇒ (2, 4)

(-5, 6) ⇒ (-5, -6)

b) Reflection in the line y=x swaps the x- and y-coordinates:

(x, y) ⇒ (y, x)

(3, 4) ⇒ (4, 3)

(2, -4) ⇒ (-4, 2)

(-5, 6) ⇒ (6, -5)

At a school, there are 120 athletes. The ratio of boy athletes to girl athletes is 3:5. How many of the athletes are girls?

FinnZ [79.3K]

There are 75 girls because you add the ratio 3+5 = 8 then divide 120 by 8 to get 15 then there are 5 lots of girls so multiply 15 x 5 to get 75

hope this helps !

Kate bought a T-shirt for $12.95 and a pair of shorts for $10.95. She paid 6.25% in tax. What is her total amount that she paid?

sergeinik [125]

Kate paid $25.39 for her purchases.

Kate will receive $24.61 in change.

Step-by-step explanation:

Given,

Cost of t-shirt = $12.95

Cost of pair of shorts = $10.95

Total = cost of t-shirt + cost of pair of shorts

Total = 12.95 + 10.95 = $23.90

Sales tax = 6.25% of total amount

Amount of sales tax = $\frac{6.25}{100}*23.90=\frac{149.375}{100}$

Amount of sales tax= $1.49

Total amount with sales tax = 23.90 + 1.49 = $25.39

Kate paid $25.39 for her purchases.

Amount paid = $50

Change received = Amount paid - Bill amount

Change received = 50 - 25.39 = $24.61

Kate will receive $24.61 in change.

FIND THE AREA...!!!!!

k0ka [10]

I think C I’m not sure but if you want me to explain I multiplied 12 x 10 and 20 x 6 and they both equal 120. So then I added 120 + 120 and got 240. Then u just added 8 because 8 was never use. Which will now look like 240 + 8 and that equal 248. :)
