Answer 1

Answer:

60° 60° 60°

60°

Step-by-step explanation:

In any triangle, the sum of its interior angles is 180°, and 60+60+60=180.

As for the other question, we can see that angle5=angle1, and angle6=angle2, due to the parallelism of the lines.

Angle5+angle6=180°, therefore

Angle6=180-120=60°=angle2

1. A finance company charges $55 simple interest on a sum of money which is
borrowed for five months. Given that the rate
of interest is 12% per annum, find the sum of
the money.

Options:
1) $1200
2) $1100

Answers

Answer:

$1100 approx

Step-by-step explanation:

Given data

SImple interest = $55

Time= 5 months in years = 5/12= 0.42 years

rate= 12%

Let the sum be P, that is the principal

The expression for the interest is given as

SI=PRT/100

substitute

55= P*12*0.42/100

Cross multiply

5500=5.04P

P= 5500/5.04

P= 1091.2

Hence the Principal is $1100 approx

Bentley is deciding between two landscaping companies for his place of business company A charges $40 per hour and $175 equipment fee company B charges $50 per hour and a $125 equipment fee let A represent the amount company b would be

Answers

Answer:

A = 40x + 175

B  = 50x + 125

5 hours

Step-by-step explanation:

The equations are as follows:

According to the question

Let us assume the number of hours be x

For company A

40x + 175

For company B

50x + 125

Now equate these two equations

40x + 175 = 50x + 125

175 - 125 = 10x

x = 5

Hence, the number of hours is 5

Answer:

[tex]y = -3+ rx[/tex]

Step-by-step explanation:

Given

[tex]Base = -3C[/tex]

[tex]Time = x[/tex]

Step-by-step explanation:

2W=74-2L

2(2W)+2(L/2)=76

substitute 74 - 2L for 2W in the last equation to solve for L. Put that value in the first equation to find W. Check by putting both values into the last equation.

There are 10 doors to a coliseum. In how many ways can a person go in and out if one can enter any door but leave using another door? Use permutation formula (P(n,r)) to solve.

Answer:

90 is the answer

Step-by-step explanation:

P(10,2) = [tex]\frac{10!}{(10-2)!}[/tex] = [tex]\frac{10!}{8!}[/tex] = [tex]\frac{10x9x8!}{8!}[/tex]
