Step-by-step explanation:
Speed = Distance/Time = 7,794/18 = 433 mph
I need help with this please the answers I can choose from are
A. 53°
B.27°
C.100°
D.80°
Sum of interior angles of a △ = 180°
∴ ∠T + ∠V + ∠U = 180°
⇒ 37° + 63° + X° = 180°
⇒ X° + 100 = 180°
⇒ X° = 180° - 100°
⇒ X° = 80° (D).

Is it possible for a triangle to have the three angle measurements 7cm, 24cm, 25cm and is it congruent or not?
Answer:
The Answer is yes to both of your questions.
Step-by-step explanation:
SSS (Side angle Side) = Because If 3 sides of triangle are congruent to 3 sides of another triangle, the triangles are congruent. SAS (Side angle side) = If 2 sides and the angle in between are congruent to the corresponding parts of another triangle, the triangles are congruent.

What is X
I will give Brainliest
Answer: x=1/2
Step-by-step explanation: You want to get the x on one side of the equal sign, by itself. First you subtract (18/4) from both sides. 5 - (18/4) =1/2 So that’s your answer.

Two numbers differ by 5. The sum of their squares is 193. Find the numbers.
Answer:
Let one number be x and the other be (x-5)
Step-by-step explanation:
x^2+(x-5)^2=193
x^2+x^2-10x+25=193
2x^2-10x+25=193
Subtract 193 from both sides of the equation.
2x^2-10x-168=0
x=12 or x=-7
x-5=7 or x-5=-12

what is the linear equation of (0.5,10) and -4.5,-10
Answer:
The linear equation containing the points (0.5, 10) and (-4.5, -10) will be:
[tex]y=4x+8[/tex]Please check the attached graph also.
Step-by-step explanation:
Given the points
(0.5, 10)(-4.5, -10)Finding the slope between (0.5, 10) and (-4.5, -10)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0.5,\:10\right),\:\left(x_2,\:y_2\right)=\left(-4.5,\:-10\right)[/tex]
[tex]m=\frac{-10-10}{-4.5-0.5}[/tex]
Refine
[tex]m=4[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointsubstituting the values m = 4 and the point (0.5, 10) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 10 = 4(x-0.5)[/tex]
Add 10 to both sides
[tex]y-10+10=4\left(x-0.5\right)+10[/tex]
Simplify
[tex]y=4x+8[/tex]
Therefore, the linear equation containing the points (0.5, 10) and (-4.5, -10) will be:
[tex]y=4x+8[/tex]Please check the attached graph also.

In a normally distributed data set with a mean of 24 and a standard deviation of 4.2, what percentage of the data would be between 19.8 and 28.2 and why
Answer:
By the Empirical Rule, 68% of the data would be between 19.8 and 28.2
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 24
Standard deviation = 4.2
What percentage of the data would be between 19.8 and 28.2
19.8 = 24 - 4.2
28.2 = 24 + 4.2
So within one standard deviation of the mean
By the Empirical Rule, 68% of the data would be between 19.8 and 28.2

For each expression, write an equivalent expression by applying the distributive
property.
2. (x + 4)(2x - 1)
The equivalent expressions are:
x² + 11x + 18
2x² + 7x - 4
x² - 10x + 25
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
(x + 2) (x + 9)
(x + 4) (2x - 1)
(x - 5)²
Now,
Applying the distributive property.
1)
(x + 2) (x + 9)
x² + 9x + 2x + 18
x² + 11x + 18
2)
(x + 4) (2x - 1)
2x² - x + 8x - 4
Combining the like terms.
2x² + 7x - 4
3)
(x - 5)²
(x - 5) (x - 5)
x² - 5x - 5x + 25
x² - 10x + 25
Thus,
The equivalent expressions are:
x² + 11x + 18
2x² + 7x - 4
x² - 10x + 25
