Answer:
She traveled 45 miles in 1 hour She traveled 270 miles in 6 hours She traveled 360 miles in 8 hoursStep-by-step explanation:
If Mrs. Anglin traveled at a speed of 90 miles in 2 hours, it means that her speed per hour is:
= 90/2
= 45 mph
If she is travelling at 45mph then in 1 hoour she would have traveled 45 miles.
In 6 hours she would have traveled:
= 45 * 6
= 270 miles
In 8 hours she would have traveled:
= 45 * 8
= 360 miles

What is the y intercept of this line?
Answer:
-2 i think
Step-by-step explanation:
(0,4) or 4
Solution:The y-intercept is the point where the graph intersects the y-axis.It's usually written as (0, b) where "b" stands for the y-intercept.Since the line intersects the y-axis at (0, 4) the y-intercept is (0,4) or 4.Hope it helps.

Is y=-3.5x-10 proportional
Answer: =3.5x Slope:
3.5
y-intercept:
0
Step-by-step explanation:
y=-3.5x-10 is an inverse proportional.
Given that, the given equation is y= -3.5x-10.
What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".
Put x=0, 1, 2, 3, and 4 in the given equation.
When x=0
y=-10
When x=1
y=-3.5(1)-10
=-3.5-10
=-13.5
When x=2
y=-3.5(2)-10
=-7-10
=-17
When x=3
y=-3.5(3)-10
=-10.5-10
=-20.5
Here, x increases and y decreases, it is inverse proportionality
Therefore, y=-3.5x-10 is an inverse proportional.

Find the value of x.
Answer:
-5
Step-by-step explanation:
Distribute 4(x+6) = 4x+6
Since the angle are congruent to eachother set them equal to oneanother
4x+6 = 5x+11
Subtract 4x on both sides.
6 = x+11
Subtract 11 on both sides.
-5 = x

Answer:
Slope of the graph is steeper.
The answer is: [tex]\mathbf{Slope=\frac{1}{3}}[/tex]
Step-by-step explanation:
First we will find slope of the graph.
The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We need to find two points from the graph to find the slope.
Let we take point 1 (-2,1) and point 2 (1,2)
We will have: [tex]x_1=-2, y_1=1, x_2=1, y_2=2[/tex]
Now finding slope of the graph
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{2-1}{1-(-2)} \\Slope=\frac{2-1}{1+2}\\Slope=\frac{1}{3}[/tex]
So, slope of the graph is: [tex]\mathbf{Slope=\frac{1}{3}}[/tex]
Now, we will find slope of Linear function.
It has x-intercept of 1 and y-intercept of -2
x-intercept means y=0
So, the point will be: (1,0)
y-intercept means x=0
So, the point will be: (0,-2)
We will have: [tex]x_1=1, y_1=0, x_2=0, y_2=-2[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-2-0}{0-(1)} \\Slope=\frac{-2-0}{0+1}\\Slope=\frac{-2}{1}\\Slope=-2[/tex]
So, the slope of linear function is: [tex]\mathbf{Slope=-2}[/tex]
Now, we need to find which of the slope is steeper.
The larger the value of slope, more steeper it is:
Now, comparing the slopes:
The slope of the graph is: [tex]\mathbf{Slope=\frac{1}{3}}[/tex]
The slope of linear function is: [tex]\mathbf{Slope=-2}[/tex]
We know that, [tex]\frac{1}{3}>-2[/tex]
So, Slope of the graph is steeper.
The answer is: [tex]\mathbf{Slope=\frac{1}{3}}[/tex]

Step-by-step explanation:
On a softball field, home plate is 43 feet from the pitcher’s mound. A ball is hit at an angle of 27° east of the pitcher’s mound. The ball travels 162 feet before it is caught by an outfielder.
A triangle is drawn on a baseball field. A point is at home plate, another point is at the pitcher apostrophe s mound, and another point is at an outfielder. The distance from home plate to the pitcher is 43 feet. The distance from home plate to the outfielder is 162 feet. The angle between the 2 sides is 27 degrees.
Law of cosines:
How far must the outfielder throw the ball to return it to the pitcher? Round to the nearest foot.
112 feet
125 feet
145 feet
156 feet
Answer: The answer is 125ft
Step-by-step explanation: I just did it
The law of cosines formula gives the square of the distance the
outfielder must throw the ball.
Correct response:
The distance the outfielder must throw the ball to return it to the pitcher is approximately 125 feet.How to use the cosine rule to find the distanceDistance of the home plate from the pitcher's mound = 43 feet
Angle at which the ball is hit = 27° east of the pitcher's mound
Distance the ball travels before it is caught = 162 feet
The sides, b and c, and the included angle, A, of the triangle drawn are respectively;
b = 43 feet
c = 162 feet
A = 27°
The length of the third side, a of the triangle is the distance from the outfielder to the pitcher.
According to law of cosines, we have;
a² = b² + c² - 2·b·c·cos(A)
a² = 43² + 162² - 2 × 43 × 162 × cos(27°) ≈ 15679.497105
Approximating to the nearest foot, we get;
a ≈ 125 feet
The distance the outfielder must throw the ball to return it to the pitcher is a ≈ 125 feet.Learn more about the law of cosines here:

2x + 7 = 19
X=?
Which one is the answer
Answer:
x=6
Step-by-step explanation:
first you subtract 7 and 7 and you also have to subtract 7 and 19 and the answer will be 12 then you divide 2 and 2 to make it only x so if you divide 2 and 2 you also have to divide the 12 so 12 divided by 2 equal 6 so the x is equal to 6

The spinner is spun 120 times. What is a reasonable
prediction for the number of times the spinner will
land on an even number?
any answers? im bit stuck on this
Step-by-step explanation:
The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.
Statement A. (vertical angles are congruent)
Statement D. (right angles are congruent)
Triangle AEC is similar to triangle BDC.
Statement E is true but does not help.
Correct statement of proportional side lengths:
BD/AE = CD/CE
x/150 = 200/50
x/150 = 4
x = 600
P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.
