Answer:
Step-by-step explanation: 10/2 = 5
20^2= x^2 + 5^2
400=x^2+25
x^2=375
x= 19.4
Answer:
h = 19.36 cm
Step-by-step explanation:
using Pythagorean theorem
20^2-5^2 = h^2
h^2 = 375
h = 19.36 cm
The length of a diagonal of a square is 10 square root of 2 inches. Find the length of one side of the square.
Answer:
10inches
Step-by-step explanation:
Let the length of one side of the square be a
If the diagonal of a square is 10√2 inches
According to pythagoras theorem
a²+a² = (10√2)²
2a² = 100(2)
2a² = 200
a² = 200/2
a² = 100
a = √100
a = 10
Hence the length of one side of the square is 10inches
Solve for the variable

What is the equation of this graph?
Answer (assuming it is allowed to be written in slope-intercept form):
[tex]y = -\frac{2}{3} x + 1[/tex]
Step-by-step explanation:
When knowing a line's y-intercept and its slope, you can write its equation using slope-intercept form, or [tex]y = mx + b[/tex].
1) First, find the slope of the line. Read the graph and look at the two points marked on the line - they are (0,1) and (3,-1). Use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] , substitute the x and y values of those points, and solve:
[tex]\frac{(-1)-(1)}{(3)-(0)} \\= \frac{-1-1}{3-0} \\= \frac{-2}{3}[/tex]
Thus, the line's slope is [tex]-\frac{2}{3}[/tex].
2) Now, use the slope-intercept formula, [tex]y = mx + b[/tex], to write an equation. Substitute the [tex]m[/tex] and [tex]b[/tex] for real values.
The [tex]m[/tex] represents the slope, so substitute [tex]-\frac{2}{3}[/tex] in its place. The [tex]b[/tex] represents the y-value of the y-intercept, or the point at which the line crosses the y-axis. Looking at the graph, we can see that the line intersects the y-axis at (0,1). Thus, substitute 1 for [tex]b[/tex]. This gives the following equation and answer:
[tex]y = -\frac{2}{3} x + 1[/tex]

simplify the problem (2y−6)^2
Answer:
4y^2-24y+36
Step-by-step explanation:
Expand the expression to simplify, which you do by using the FOIL method, then combining like terms.
(a-b)(a-b) = a^2 - 2ab + b^2
(2y-6)^2
= (2y-6)(2y-6)
= 4y^2 - 12y + 36

Step-by-step explanation:
Brown Delivery Company delivers its standard crates using a fleet of vans and trucks. A van can hold up to 20 standard
crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard
crates at one time using 12 vehicles, which system of linear equations could be used to determine the number of vans, x,
and the number of trucks, y, needed for this delivery?
x + y = 12
20x + 35y = 270
x + y = 270
20x + 35y = 12
x + y = 12
35x + 20y = 270
x+y = 270
35x + 20y = 12
Answer:
x + y = 12
20x + 35y = 270
Step-by-step explanation:
Let us represent:
The number of vans = x
The number of trucks = y
From the above question, we are told that:
A van can hold up to 20 standard crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard crates at one time using 12 vehicles.
Hence, our system of equations is given as:
x + y = 12..... Equation 1
20 × x + 35 × y = 270
= 20x + 35y = 270...... Equation 2
find the equation of a line that is parallel to the straight line 2x-y=-3 and crosses the x-axis at x=-5
Answer:
y=2x+10
Step-by-step explanation:
In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.
In this case it is y=2x+3
All parallel lines have the same gradient. The gradient of this line = 2.
If the line crosses the x axis at x=-5, then when x =-5 y = 0.
If you put all this in the form y =ax + b you get 0 = 2(-5) +b
So all you need to do to find b is rearrange. b = 10.
Therefore your line has gradient 2 and y intercept 10.
y = 2x + 10
