We can set the length of the rectangle to l. We can make an equation with the area because we know length*width = area.
l*(4/5) = 7/5
4l = 7
l = 7/4 = 1 3/4

Part A:
Draw arrows on the graph below for RISE and RUN. *Remember to start at the left point.*
Part B: Find the slope of the line from the graph above. *Don't forget to simplify!*
Answer:
Option D
Step-by-step explanation:
A). From the graph attached,
Arrow AB represents the RISE and arrow BC represents the RUN.
B). RUN from point A to B (Horizontal distance) = 2 units
Rise from point A to B (Vertical distance) = -4 [Since, downwards arrow represents negative notation]
Slope of the line segment AB = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-4}{2}[/tex]
= -2
Therefore, slope of the line = slope of the line segment AB = -2
Option D will be the correct option.

Tides are measured by the heights of the tide above or below sea level. The difference between the two heights represents how much greater the high tide is than the low tide. The table shows the high and low tides and the difference between their heights at each of three locations. Some of the data in the table are missing. Use this information for the problem below.
Answer: Location A: 6.04, since a negative and a negative is a positive. 6.04--1.08=7.12
Location C: 6.9
7.34-0.44=6.9
Step-by-step explanation:
Difference between high tide and low tide at location C is equal to 6.9 and high tide at location A is equal to 6.04
What is high tide and low tide ?Tides originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface. When the highest part, or crest of the wave reaches a particular location, high tide occurs; low tide corresponds to the lowest part of the wave, or its trough.
Given here Difference between high tides and low tides = high tide - low tide
= HT - LT . . . . . . . (1)
thus, Difference between high tide and low tide at location C is = 7.34 -0.44
= 6.9
And high tide at location A is = (Difference between HT & LT) + LT (from eqn 1)
= 7.12 + ( -1.08)
= 6.04
Hence, Difference between high tide and low tide at location C is equal to 6.9 and high tide at location A is equal to 6.04

Which is the better deal?
Cheerios
12 oz. for $ 1.99
36 oz. for $2.59
48 oz. for $3.99
60 oz. $4.59
Answer:
36 oz
Step-by-step explanation:
Get the other options down to 12oz units for their price and then you can compare which one is the cheapest for 12oz.
12oz = $1.99
36oz/3 = 12oz so $2.59/3 = $ .86
48oz/4= 12oz so $3.99/4 = $1.00
60oz/5= 12oz so $4.59/5 = $ .92
So looking at the breakdown, the 36oz one is the cheapest because for that price for a third of it comes out to .86 cents.

Step-by-step explanation:
You want to isolate the 'y' in each inequality:
4x - 5y ≤ 1
-5y ≤ -4x + 1
y ≥ 4/5x - 1/5 (inequality symbol changed because we divided by a negative)
1/2y - x ≤ 3
y - 2x ≤ 6 we multipled the original inequality by 2 to eliminate the denom.
y ≤ 2x + 6

a pentagon has a total of 540 degrees
105, 115, 110, 180-2x, 180-3x are the interior angles (subtract each from 180 because they're on lines)
540= 105+115+110+(180-2x)+(180-3x)
540=330 +(180-2x)+(180-3x)
210=360-5x
-150=-5x

Answer:1. 1.0 1.0 1.4
Step-by-step explanation:
The length of the sides are given by the 45°–45°–90° triangle theorem.
Correct responses:
AB = 1AC = 1BC = √2 Methods used to find the lengthsThe 45°–45°–90° triangle theorem states that the ratio of the lengths of
the sides of triangles having interior angles of 45°, 45°, 90° is 1 : 1 : √2
The lengths of the legs of an isosceles triangle are equal.
The legs of the given isosceles right triangle are AB and AC
Therefore;
AB = AC
Taking the lengths of AB as 1 unit, we have;
AB = 1 = AC
According to Pythagorean theorem, we have;
[tex]\overline{BC}^2 = \mathbf{\overline{AB}^2 + \overline{AC}^2}[/tex]
Which gives;
[tex]\overline{BC}^2 = 1^2 + 1^2 = \mathbf{ 2}[/tex]
Therefore;
BC = √2
Therefore, by setting the length of AB = AC = 1, we have;
AB = 1AC = 1BC = √2 ≈ 1.414The above values are in the ratio 1 : 1 : √2, which corresponds with the
45°-45°-90° triangle theorem.
