Work out the unknown angles. Give reasons for each answer.

zalisa [80]

A)

Because the sum of angles in a triangle must equal 180° we can say:

62+α+90=180

α+152=180

α=28°

b)

Since all sides have equal length, all angles must have equal measure. (This is an equilateral triangle). And again, because the sum of the angle must be 180° we can say:

b+b+b=180

3b=180

b=60°

Fred buys a binder for $4.50 and six reams of paper. Latasha buys an ink cartridge for $17.50 and four reams of paper. Both spen

kondor19780726 [428]

Answer:

The the price of one ream of paper is $6.5.

Step-by-step explanation:

Here, Let us assume the cost of one ream of paper = $ m

<u>The money spent by Fred:</u>

The money spent on a binder = $4.50

The money spent on 6 ream of papers = 6 x ( cost of 1 ream )

= 6 x ($m) = 6 m

⇒The total money Fred spent = Money spent on (binder + 6 ream of papers)

= 4.50 + 6 m ....... (1)

<u>The money spent by Latasha:</u>

The money spent on a cartridge = $17.50

The money spent on 4 ream of papers = 4 x ( cost of 1 ream )

= 4 x ($m) = 4 m

⇒The total money Latasha spent = Money spent on (cartridge + 4 ream of papers)

= 17 .50 + 4 m .... (2)

Also, Both spend the same amount of money

⇒4.50 + 6 m = 17 .50 + 4 m ( from (1) and (2))

or, 6 m - 4 m= 17. 50 - 4, 50

or, 2 m = 13

or, m = 13/ 2 = 6.5

So, the value of m = $6.5

Hence, the the price of one ream of paper is $6.5.

1. Kristen spent $131 on shirts at Target last week. She bought some fancy shirts for

Masja [62]

Answer:

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Step-by-step explanation:

Given that,

Kristen spent $131 on 7 shirts.

Cost of one fancy shirt = $28

Cost of one plain t-shirt = $15

Let,

x be the number of fancy shirts

y be the number of plain t-shirts

x+y = 7 Eqn 1

28x+15y=131 Eqn 2

Multiplying Eqn 1 by 15

15(x+y=7)

15x+15y=105 Eqn 3

Subtracting Eqn 3 from Eqn 2

(28x+15y)-(15x+15y)=131-105

28x+15y-15x+15y=26

13x=26

Dividing both sides by 13

$\frac{13x}{13}=\frac{26}{13}\\x=2$

Putting x=2 in Eqn 1

2+y=7

y=7-2

y=5

Hence,

Kristen bought 2 fancy shirts and 5 plain t-shirts.
