Today, the mailman sorted 57 letters during his first hour of work, 69 letters during his second hour, 81 letters during his thi

mars1129 [50]

The answer is 93

If we sorted out the number of each hours, the sequence will look like this

57 _ 69 _ 81 _ x _ 105

(in which x is the fourth hour of work)

We can see from the sequence that each hours, the mailman add additional 12 letters.
(69 - 57 = 12)
(81 - 69 = 12) . . . . proof

So, the amount of letters on the fourth hour would be:
81 letters + 12 letters = 93 Letters

HELP ME PLEASE HURRY: Wade has claims that quadrilateral ABCD is a square because he has found that all four sides are congruent

RUDIKE [14]

Answer:

At first we should know that:

The properties of the square are:

It has four equal sides.
All angles are right angles or equal to 90º.
The sum of its all angles is 360º
It has two pairs of perpendicular lines.
It has two pairs of parallel lines.

The properties of Rhombus

It has equal four sides.
The opposite sides are of the same length.
It has two acute angles and two obtuse angles.
The sum of its all angles is 360º
It has zero pairs of perpendicular lines.
It has two pairs of parallel lines.

So, Wade is incorrect because the quadrilateral may be Rhombus

And the quadrilateral to be a square, she needs to show that It has two pairs of perpendicular lines.

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.

Boyd grows only tomatoes and raspberries in his garden. Last year, he grew 140 pounds of tomatoes and 60 pounds of raspberries.

nadya68 [22]

Answer:

29%.

Step-by-step explanation:

We have been given that Boyd grew 140 pounds of tomatoes and 60 pounds of raspberries. This year, the production, by weight, of tomatoes declined by 20 percent, and the production, be weight, of raspberries declined by 50 percent.

First of all, we will find the weight of tomatoes and raspberries using the given information.

Since the production, by weight, of tomatoes declined by 20 percent, so this year production of tomatoes is 80% of 140 pounds.

$\frac{80}{100}\times 140=0.80\times 140=112$
