The following set of coordinates represents which figure? (1, 1), (5, 3), (7, 7), (3, 5) (4 points)

8 0

Check the slopes
the first 2 points have slope (3-1) / (5-1) = 2/4 = 1/2
points 2 and 3 slope = 4/2 = 2
3 and 4:- slope = -2/-4 = 1/2
4 and 1:- slope = 4/2 = 2

so we have 2 pairs of opposite sides which are parallel

looks like a parallelogram or a rhombus

if adjacent sides are equal its a rhombus

length betwee pts 1 and 2 = sqrt(2^2 + 4^2) = sqrt20
.. ... ... .. .. .. ...2 and 3 = sqrt(4^2 + 2^2) = sqrt20

so it is a rhombus

Angles a and b are complementary angles symmetry of angle a is 28° more than the measure of angle b find the missing angle measu

scoray [572]

Answer:

31 , 59

Step-by-step explanation:

a = b +28

a + b = 90 {Complementary}

b + 28 + b = 90 {Combine like terms}

2b + 28 = 90 {Subtract 28 form both sides}

2b = 90 - 28

2b = 62 {Divide both sides by 2}

b = 62/2

b = 31

a = 31 + 28

a = 59

Henry places £6000 in an account which pays 4.6% compound interest each year

aivan3 [116]

Answer:

£ 6,564.70

Step-by-step explanation:

Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years

Compound Interest formula =

A = P(1 + r/n)^nt

A = Final Amounrt

P = Principal = £6,000

r = Interest rate = 4.6%

t = Time in years = 2 years

n = Compounding frequency = Yearly = 1

First, convert R percent to r a decimal

r = R/100

r = 4.6%/100

r = 0.046 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 6,000.00(1 + 0.046/1)^(1×2)

A = £ 6,564.70

The amount in his account after 2 years = £ 6,564.70

In a group of 60 workers, the average salary is $80 a day per worker. if some of the workers earn $75 a day and all the rest ear

Softa [21]

The total number of workers that earn $75 per day is 48

<h3>What is average salary?</h3>

The average salary is calculated based on reported salaries of respondents. The average salary definition is to add the salaries in the sample together, then divide by the number of respondents.

Given that:

In a group of 60 workers, the average salary is $80 a day per worker.

If some of the workers earn $75 a day and all the rest earn $100 a day.

Let 'x' be the total number of workers that earn $75 per day.

So, the total number of workers that earn $100 per day is (60 - x).

As the average salary of 60 workers is $80.

Then,

$\frac{75x + 100(60-x)}{60} =80$

or, 75 x + 6000- 100x = 80*68

or, -25x= -1200

x= 48

So, the total number of workers earn $75 per day is 48.
