(REPOST) Helen went with her mother to a fabric Sale. on the sale table, fabric was marked 25% off. The regular price of a certain bolt of fabric was $7.79 a yard A. Round to the nerest dollar and estimate the cost of 4 yard at regular price. _
B. Change the percent into a fraction to estimate the discount and the sale price of 4 yards
SOMEONE OUT TJHERE PLEASEEE I BEGGED YOU TO HELP ME... THIS IS CONFUSING SOMEONE PLEASEEE HELP ME OUT. I WILL ALSO MARK BRAINLIEST. SO PLEAS HELP ME PLEASEEE LIKE RIGHT NOW PLEASE HLEP ME

7.79--->8.00

8×4=32

$32 for 4 yards

25/100

$2.00 off

Cost=$24.00

amount saved= $8.00

Step-by-step explanation:

50% of $8 is $4

So 25% of $8.00 is $2.00

2.00×4(yards)= $8.00

32-8=24.00

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
