Step-by-step explanation:
Long story short it's 3, how do I know without calculating? because this is the most common example used when people start learning about the Pythagorean theorem. 3^2 + 4^2 = 5^2
But anyways here is how to solve it
The formula for these questions is a^2 + b^2 = c^2, otherwise known as the Pythagorean theorem. a and b represent the sides that are going vertically and horizontally, doesn't matter which is which. c is the line going down diagonally, also known as the hypotenuse.
So here
a^2 + b^2 = c^2, replace b or a doesn't matter with 4 and c with 5 specifically.
a^2 + 4^2 = 5^2, now just solve for a
a^2 + 16 = 25
a^2 = 9
[tex]\sqrt{a^2} = \sqrt{9}[/tex]
a = 3

The equation of the situation is:

If the recipe calls for 16 ounces of flour, the number of ounces of sugar will be:
x = 2Step-by-step explanation:
Part a) Determining the equation
Given the number of ounces of flour 'y' is proportional to the number of ounces of sugar 'x'.
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
Here, k is the constant of direct variation.Given
y = 48
x = 6
y = kx
k = y/x
k = 48/6
k = 8
Thus, the constant of direct variation = k = 8
Therefore, the equation that represents the equation
y = kx
substituting k = 8 in the equation
y = 8x
Therefore, the equation of the situation is:
y = 8xPart b) Determining the ounces of sugar i.e. 'x' when ounces of
flour = y = 16
Given
y = 16
k = 8
Ounces of sugar = x = ?
Using the equation
y = 8x
substituting y = 16
16 = 8x
8x = 16
dividing both sides by 8
x = 2
Therefore, if the recipe calls for 16 ounces of flour, the number of ounces of sugar will be:

6) Two angles are called supplementary when their measures add up to 180 degrees. For example, two right angles are supplementary angles.
7) When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.
8) you have to plot the points on the graph and draw a line and label it with L at one point and M at another point.
9) x = 20
m < A = 65
m < B = 25
Step-by-step explanation:
9)
3x + 5 + 2x - 15 = 90
3x + 2x + 5 - 15 = 90
5x - 10 = 90
5x - 10 + 10 = 90 + 10
5x = 100
5 / 5x = 100 / 5
x = 20
A = 3x + 5
A = 3(20) + 5
A = 60 + 5
A = 65
B = 2x - 15
B = 2(20) - 15
B = 40 - 15
B = 25

Paul, a car salesman earns 2.5% of everything he sells in commission. Last week he solda car for $26,000.
How much money did he make last week?
Answers
Answer:
$650
Step-by-step explanation:
Assuming that the car is the only one he sold that week, multiply $26,000 by 0.025 since it is 2.5% earned and you will get the answer $650.
Answer: $650.
Step-by-step explanation;
Step 1: Our output value is 26000.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, $26000=100%.
Step 4: Similarly, x=2.5%.
Step 5: This results in a pair of simple equations:
26000=100%(1).
x=2.5%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have :
26000/x = 100%/2.5%
Step 7: Again, the reciprocal of both sides gives :
x/260000 = 2.5/100
x=650
Therefore, the 2.5% of 26000 is 650.

The correct option is (b).
Step-by-step explanation:
Given that,
Miranda is calculating her expected expenses for her week long trip to Turkey.
Flight cost = 928 TL
Lodging costs = 755 TL
She spend 814 TL for food.
We need to find Miranda's total. It is equal to the sum of all above data such that,
Total = 928+755+814
= 2497 TL
Hence, Miranda's total is 2497 TL.

Consider the quadratic function: y = 2x^2 + 7x + 10
What is the y-intercept? [Select]
Does the function open up or down? (Select]
Does the function have a maximum or a minimum? [Select ]
Answers
Answer:
y-intercept: 10
concavity: function opens up
min/max: min
Step-by-step explanation:
1.) The definition of a y-intercept is what the resulting value of a function is when x is equal to 0.
Therefore, if the function's equation is given, to find y-intercept simply plug in 0 for the x-values:
[tex]y = 2x^2+7x+10 = 2(0)^2 + 7(0)+10 = 2(0) + 0 + 10 = 0 + 10 = 10[/tex]
y intercept ( f(0) )= 10
2.) In order to find concavity (whether a function opens up or down) of a quadratic function, you can simply find the sign associated with the x^2 value. Since 2x^2 is positive, the concavity is positive. This is basically possible, since it is identifying any reflections affecting the y-values / horizontal reflections.
3.) In order to find whether a quadratic function has a maximum or minimum, you can use the concavity of the function. The idea is that if the function opens downwards, the vertex would be at the very top, resulting in a maximum. If a function was open upwards, the vertex would be at the very bottom, meaning there is a minimum. Like the concavity, if the value associated with x^2 is positive, there is a minimum. If it is negative, there is a maximum. Since 2x^2 is positive, the function has a minimum.
