Use the information below to find EF such that triangle ABC is congruent to triangle DEF

Nikolay [14]

Check the picture below.

notice, the green numbers are the given ones, and the red ones are the implicit ones.

since we know both triangles are congruent, then all their sides as well as angles are congruent as well.

so if triangle ABC has sides of 24 and 36, so does triangle DEF, and if triangle DEF has a side of 48, so does triangle ABC.

Paul has $20000 to invest. He can invest part of his money at 6% and the rest at 4%. How much does paul have to invest at each r

jek_recluse [69]

Answer: he should invest $15000 at 6% and $5000 at 4%

Step-by-step explanation:

Let x represent the part of his money that he should invest at 6%.

Let y represent the part of his money that he should invest at 4%.

Paul has $20000 to invest. He can invest part of his money at 6% and the rest at 4%. It means that

x + y = 20000

The interest that he would earn on the amount invested at 6% after 1 year is

6/100 × x = 0.06x

The interest that he would earn on the amount invested at 4% after 1 year is

4/100 × y = 0.04y

if he wants to get a total of $1100 interest on his $20000, it means that

0.06x + 0.04y = 1100- - - - - - - - - 1

Substituting x = 20000 - y into equation 1, it becomes

0.06(20000 - y) + 0.04y = 1100

1200 - 0.06y + 0.04y = 1100

- 0.06y + 0.04y = 1100 - 1200

- 0.02y = - 100

y = - 100/-0.02

y = 5000

x = 20000 - y = 20000 - 5000

x = 15000

A tailor used 6 2/3 yards of fabric to make hats. The amount of fabric needed to make each hat is 5/6 yard. How many complete ha

vfiekz [6]

Answer: The tailor made 8 complete hats

Step-by-step explanation:

Amount of fabrics available to make hat = 6 2/3 yards

1 hat requires = 5/6 yards

Number of hat to obtain from the available fabric = Amount of fabrics available to make hat / requirement of 1 hat

=(6 2/3) / (5/6)

(20/3) / (5/6)

20/3 x 6/5 = cancelling out, we are left with

4x2= 8 hats

(20/3) / (5/6)

6.6666 /0.83333

= 8.00002= 8 hats
