Answer:
7.62
Step-by-step explanation:
To calculate the distance we can set up a right triangle and use the pythagorean theorem to calculate the distance.
A^2 + B^2 = C^2
Keep in mind that the A and B in this theorem (and my proceeding work) does not correlate to the labels for the points in the problem and are the standard variables used in the theorem.
First lets find the lengths of the sides A and B of our triangle by determing the distance on each axis that seperates the points.
On the x-axis we have
A = 5 - 2
A = 3
The y-axis has
B = 4 - (-3)
B = 7
Plugging these values into the equation from earlier we get:
3^2 + 7^2 = C^2
Where C is the hypotenuse of the right triangle we have created, and the distance between the two points.
9+49 = C^2
sqrt(58) = C
7.615773106 = C
Rounded the the nearest hundredth:
C = 7.62
An earned run average (ERA) in baseball is the average number of earned runs a pitcher gives up per 9 innings. One year, a professional baseball pitcher had a 3.91 ERA. His ERA was 0.74 points lower the next year. What is the new ERA?
Applying a subtraction operation, it is found that his new ERA was of 3.17.
What is the relation between his two ERA's, in last year's and this year?ERA is a baseball concept, but understanding of baseball is not relevant to this question.
One year, a professional baseball pitcher had a 3.91 ERA. The next year, it was 0.74 points lower, hence it was given by the subtraction of 3.91 and 0.74, that is:
ERA = 3.91 - 0.74 = 3.17.
His new ERA was of 3.17.

The denominator represents the number of components into which the whole has been subdivided. It is positioned below the fractional bar in the lower section of the fraction.The numerator specifies how many fractional parts are depicted or selected. It is positioned above the fractional bar in the upper section of the fraction.As, the length of the painted area is 3 1/5 and width of the painted area is 2/3.
So, multiplication of length and width is as follows:
3 1/5 x 2/3
= 3 x 2/3 + 1/5 x 2/3
= 6/3 + 2 / 15
= 30 + 2 / 15

Using relations in a right triangle, it is found that it's area is of 302.2 units squared.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, we have that the opposite side to the angle of 25º is of x, while the adjacent side is of 36, hence:
[tex]\tan{25^\circ} = \frac{x}{36}[/tex]
[tex]x = 36\tan{25^\circ}[/tex]
x = 16.79.

1. A solution to 8 = -x + 10 is 2
Answer:
TrueStep-by-step explanation:
So, Lets find out if the solution is true or not, So first let us find the value of x.
⇒ 8 = -x + 10
We can rewrite the equation as,
⇒ -x + 10 = 8
Subtracting 10 from both sides we get :
⇒ -x + 10 – 10 = 8 – 10
⇒ -x = -2
Multiplying both sides by (-1) :
⇒ -1(-x) = -1(-2)
⇒ x = 2
Therefore,
The statement "A solution to 8 = -x + 10 is 2" is trueHey ! there
Answer:
TrueStep-by-step explanation:
In this question we are given with an equation that is 8 = -x + 10 and we have also given its solution that is 2 .And We are asked to tell whether the solution of given equation is true or false .
For finding that we must have to solve the equation .
Solution : -
[tex]\longrightarrow \qquad \: 8 = -x + 10[/tex]
Step 1 : Flipping the equation so that there's ease in solving :
[tex] \longrightarrow \qquad \: - x + 10 = 8[/tex]
Step 2 : Subtracting with 10 on both sides :
[tex] \longrightarrow \qquad \: - x + \cancel{10 }- \cancel{ 10} =8 - 10[/tex]
On further calculations , We get :
[tex] \longrightarrow \qquad \: - x = - 2[/tex]
Step 3 : Multiplying with -1 on both sides :
[tex] \longrightarrow \qquad \: - x \times - 1 = - 2 \times - 1[/tex]
We get :
[tex] \longrightarrow \qquad \: \blue{\underline{\boxed{ \frak{x = 2}}}}[/tex]
Therefore , it's TRUE that 2 is the solution of given equation .Alternative Solution : -
There's another easy way to check whether 2 is solution of given equation or not . This is done by substituting value of x that is 2 in given equation that is 8 = -x + 10 . So substituting value of x ( solution ) in given equation :
8 = - ( 2 ) + 108 = -2 + 108 = 8L.H.S = R.H.SAs we can see that left side is equal to right side .
Therefore , it's TRUE that 2 is the solution of given equation .#Keep LearningSeven people are going to share an 84-ounce bottle of soda. How many ounces will each person get to drink?

[tex]6-2x=-4x+16[/tex]
Now we simplify

So now that we know that x is equal to 5, we can find the value of y
