Answers
9514 1404 393
Answer:
√32
Step-by-step explanation:
The hypotenuse can be found using the Pythagorean theorem. It tells you the square of the hypotenuse is the sum of the squares of the legs.
h² = 4² +4²
h² = 16 +16 = 32
h = √32
The length of the hypotenuse is square root of 32 units.

Answer:
For A)
when you go from mixed number to improper fraction all you have to do is multiply the denominator (bottom number) with the whole number (the big number on the left) then finally add the numerator (on the top). After you get the answer just write the answer divided the denominator (answer/denominator) to write as improper fraction. Examples is shown below.
For B) all you have to do is switch the fraction. If it a whole number then just assume that it is divided by 1, and for mixed fraction just solve it like A then switch the fraction. Examples shown below.
Step-by-step explanation:
For A)
1. 1 (2/3) -> multiply 3 with 1 then add the 2. So, (3 x 1) +2 = 5 then write as improper fraction which is 5/3
2. 3 (3/5) -> (5 x 3) + 3 = 18 -> 18/3
and so on...
For B)
1. 3/7 -> 7/3
3. 9 which is 9/1 -> 1/9
5. 14 (1/3) -> (3 x 14) + 1 = 43 -> 43/3 -> 3/34

5. Maria is tracking the number of miles she runs in one week. She is using the track at her
school, which measures in meters.
Part A; if Maria runs 5.000 meters each week, how many miles does she rung Round your
answer to the nearest tenth. (1 meter = 1.09361 yards)
Answers
Answer:
0.00310 miles
Step-by-step explanation:
Maria runs 5 m each week. We need to find how miles she run. It means we need to convert meters to miles. The relation between meter and yards is as follows :
1 meter = 1.09361 yards
Also, 1 mile = 1760 yards
It means,
1 mile = 1609.34 m
1 m = (1/1609.34) miles
[tex]5\ m=\dfrac{5}{1609.34}\ \text{miles}\\\\=0.00310\ \text{miles}[/tex]
So, she will cover 0.00310 miles.

Answer:
Step-by-step explanation:
Answer:
1i.) x = 18
1ii.) x = 40
2.) x = 155
3i.) ABD = 115° (actually this is wrong, idk how to calculate this ;-;
3ii.) BEF = 135°
Step-by-step explanation:
*All triangles add up to 180° in total of all angles added together*
i.) Find x
4x + 3x + 3x = 180°
10x = 180°
10x/10 = 180/10
x = 18
----------------------------------------
ii.) Find x
180 - 115 = 65
65° + 75° + x° = 180°
140° + x° = 180°
x° = 180° - 140°
x = 40°
----------------------------------------
2.) Find x
180 - 145 = 35
45° + 35° + n° = 180°
80° + n° = 180°
n° = 180° - 80°
n° = 100°
*Vertical Angles of n and m (variables I randomly made so I can solve this), so they are both the same*
100 + 55 + m = 180
155 + m = 180
m = 180 - 155
m = 25
25 + x = 180
x = 180 - 25
x = 155
----------------------------------------
3.) Find Angles
i.) ABD
180° - 65° = 115°
Angle ABD = 115°
ii.) BEF
180° - 110° = 70°
70° + 65° + x° = 180
135° + x° = 180°
x° = 180° - 135°
x = 45°
180° - 45° = 135°
Angle BEF = 135°

A crew of highway workers paved 1/5 mile in 1/8 hour. If they work at the same rate, how much will they pave in one hour?
Answers
Answer:37.5
Step-by-step explanation:
The work a crew will pave in an hour will be 8/5 miles.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a crew of highway workers paved 1/5 mile in 1/8 hour. The amount of work will be calculated as,
1 / 8 hours ⇒ 1 / 5 miles
1 hour ⇒ 8 x (1 / 5 ) miles
1 hour ⇒ 8 / 5 miles
Therefore, the work a crew will pave in an hour will be 8/5 miles.

what is special about the y coordinate that goes with the x coordinate of 1 on a proportional graph
Answers
Answer and Step-by-step explanation:
There is a two-dimensional numbers line in a coordinate plane, which has a horizontal line x-axis, and the vertical line is known as the y-axis. These lines intersect each other at zero points, and they are perpendicular. Zero points are known as the origin. The axes divide the plane into quadrants.
A point in the coordinate plane is of the form of (x, y). This point is named as ordered pair; the first number is from the x coordinate, and the second number from the y coordinate.
To make a graph, we draw a dot, starting from the origin, at the coordinate that communicates to the ordered pair. The y coordinates describe how many steps to move up or down ( positive or negative), and x coordinates tell us to move right or left ( positive or negative).
The completeness property for points describes:
Exactly one point in the plane given the number of ordered pair
And
Exactly one ordered pair of numbers at a given point in the plane.
A relation is ordered pairs; the x coordinates are known as domain, and the y coordinate is known as the range.
The domain contains the value that corresponds to the independent variable and the range equal to the dependent variable.

A construction company can remove 3/4 tons of dirt from a construction site each hour. How long will it take them to remove 24 tons of dirt from the site?
Answers
Answer:
32 hours
Step-by-step explanation:
Given
[tex]Rate= \frac{3}{4}\ tons\ per\ hour[/tex]
Required
Determine time taken for 24 tons
As used in this question, Rate is the ratio of tons of dirt to time.
i.e.
[tex]Rate = \frac{Tons\ of\ Dirt}{Time}[/tex]
Let t represents time when tons of dirt is 24 tons:
[tex]Rate = \frac{24}{t}[/tex]
Recall that: [tex]Rate= \frac{3}{4}\ tons\ per\ hour[/tex]
So, we have
[tex]\frac{24}{t} = \frac{3}{4}[/tex]
Cross Multiply
[tex]3 * t = 24 * 4[/tex]
Divide both sides by 3
[tex]t = 8 * 4[/tex]
[tex]t = 32[/tex]
Hence, time taken is 32 hours
