First, let's get the unit rate.
1.5 hours for 915 miles, so
[tex]\frac{1.5 hours}{915 miles} = \frac{1 hour}{x.miles}[/tex]
Cross multiplying gives us 1.5x = 915, divide by 1.5, and we get 610 miles. This is the answer for the top left. This means the plane was going 610 mph.
The speed will be constant because it tells us this.
Then, we multiply 610 by the time to fill in the rest of the distances.
For t, we can figure out the distance is 610 times t, as you can see I have written down.
See attached file below.
I hope this helps, have a nice day! :D

Find f(2)
Answer:
f(2)= -2
Step-by-step explanation:
according to the proper question on the photo
f(x)= -2x²-2x+10
f(2)= -2(2)²-2(2)+10
f(2)= -2(4)-4+10
f(2)= -8-4+10
f(2=-12+10
f(2)= -2
Midpoints
B is the midpoint of AC , find x.
B is the midpoint which means both sides are equal to each other:
5x = 3x + 4
Subtract 3x from both sides
2x = 4
Divide both sides by 2
X = 2

Step-by-step explanation:
There are some property you need to know
one external angle of a triangle equals to the sum non-adjacent angles of the triangle.The sum of all interior angles is 180(deg)According to the graph we have [tex]125^\circ=(x+2y)^\circ+90^\circ\\(x+2y)^\circ = 35^\circ[/tex]
And

A city map is placed on a coordinate grid. The post office is located
at the point A(3, 8), the library is located at the point B(15,9), and
the fire station is located at the point C(21, 9.5) What is the ratio of
the length of AC to the length of BC?
The length of a segment is the number of units on the segment.
The ratio of line segment AC to line segment BC is 3 : 1
The coordinate points are given as:
[tex]\mathbf{A = (3,8)}[/tex]
[tex]\mathbf{B = (15,9)}[/tex]
[tex]\mathbf{C = (21,9.5)}[/tex]
The length of each segment will be calculated using the following distance formula
[tex]\mathbf{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}[/tex]
So, we have:
[tex]\mathbf{AC = \sqrt{(3 - 21)^2 + (8 - 9.5)^2}}[/tex]
[tex]\mathbf{AC = \sqrt{326.25}}[/tex]
Also, we have:
[tex]\mathbf{BC = \sqrt{(15 - 21)^2 + (9 - 9.5)^2}}[/tex]
[tex]\mathbf{BC = \sqrt{36.25}}[/tex]
The ratio of AC to BC is represented as:
[tex]\mathbf{AC : BC = \sqrt{326.25}:\sqrt{36.25}}[/tex]
Divide through by [tex]\sqrt{36.25[/tex]
[tex]\mathbf{AC : BC = \sqrt{9} : \sqrt{1}}[/tex]
Evaluate square roots
[tex]\mathbf{AC : BC = 3 : 1}[/tex]
Hence, the ratio is 3 to 1

Solve the quadratic equation
Answer:
Our problem is [tex]x^2-2x+6=0[/tex], but as we can see, we are unable to factor. We have to use the quadratic equation to solve.
[tex]x^2-2x+6=0[/tex]
[tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]
Positive Quadratic Formula:
[tex]\frac{-(-2)+\sqrt{(-2)^2-4(1)(6)}}{2(1)}[/tex]
[tex]=\frac{2+\sqrt{4-24}}{2}\\=1+\frac{\sqrt{-20}}{2}[/tex]
Negative Quadratic Formula:
[tex]\frac{-(-2)-\sqrt{(-2)^2-4(1)(6)}}{2(1)}[/tex]
[tex]=\frac{2-\sqrt{4-24}}{2}\\=1-\frac{\sqrt{-20}}{2}[/tex]
Since both of our answers are the square root of a negative number, we know that the quadratic equation has no real solution.
*We could have also used the Discriminant Test to determine whether the quadratic equation has real roots or not. However, for our means, the quadratic equation seems enough.
Answer:
D. No real Solution
Step-by-step explanation:
Hello!
Let's use the quadratic formula: [tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
In our equation:
a = 1b = -2c = 6This comes from the standard form of a quadratic: [tex]ax^2 + bx + c[/tex]
Now, solve:
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex][tex]x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4(1)(6)}}{2(1)}[/tex][tex]x = \frac{2 \pm \sqrt{4 -24}}{2}[/tex][tex]x = \frac{2 \pm\sqrt{-20}}{2}[/tex][tex]x = \frac{2 \pm 2\sqrt{-5}}{2}[/tex][tex]x = 1 \pm \sqrt{-5[/tex]Since the radicand (-5) is negative, there are no real solutions. The correct answer is Option D.
I'll mark brianlest. Determine the value of "c" that makes x^2-13x+__ a perfect square
Answer:
c=42.25.
Step-by-step explanation:
A perfect square is number or expression that is multiplied by to numbers or expressions to make it. So for this, you would find one number that, added with itself with make -13. Which would be -6.5. So the answer will be determined by doing (x-6.5)^2 to get x^2-13x+42.25. c = 42.25
Triangle A and Triangle B are right triangles.
Triangle A has a height of 8 meters and a base of 6 meters.
Triangle B has a height that is one unit greater than triangle A and a base that is one unit less.
What is the measure of the hypotenuse of triangle A? Show your work.
Determine if the hypotenuse of triangle B has the same hypotenuse as triangle A. Justify your solution.
I. The measure of the hypotenuse of triangle A is equal to 10 meters.
II. The measure of the hypotenuse of triangle B is equal to 10.30 meters.
Given the following data:
Height A = 8 metersBase A = 6 metersTo determine the measure of the hypotenuse of triangle A, we would apply Pythagorean's theorem since the is a right triangle:
Mathematically, Pythagorean's theorem is given by the formula:
[tex]C^2 = A^2 + B^2\\\\C^2 = 6^2 + 8^2\\\\C^2=36+64\\\\C^2 = 64+36\\\\C^2=100\\\\C=\sqrt{100}[/tex]
Hypotenuse, C = 10 meters.
For Triangle B:
Triangle B has a height that is one (1) unit greater than triangle A:
Height B = 8 + 1 = 9 meters
Triangle B has a base that is one (1) unit less than triangle A:
Base B = 6 - 1 = 5 meters
To find the hypotenuse B:
[tex]C^2 = A^2 + B^2\\\\C^2 = 5^2 + 9^2\\\\C^2=25+81\\\\C^2=106\\\\C=\sqrt{106}[/tex]
Hypotenuse, C = 10.30 meters
From the above calculations , we can deduce that the measure of the hypotenuse of both Triangle A and Triangle B are different.

A baker had 3 1/4 pounds of apples. she used 3/4 to make an apple pie. How many pounds of apples does she have left
Answer:
2 1/2
Step-by-step explanation:
3 1/4 - 3/4 =2.5 which simplify's to 2 1/2
The number of pounds of apples that she has left will be 13/16 pounds.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
A baker had 3 ¹/₄ pounds of apples. she used 3/4 to make an apple pie.
Convert the mixed fraction number into a fraction number. Then we have
3 ¹/₄ = 13/4
The number of pounds of apples that she has left will be given as,
⇒ 13/4 - (13/4)(3/4)
⇒ 13/4 - (39/16)
⇒ (52/16) - (39/16)
⇒ (52 - 39) / 16
⇒ 13/16 pounds
The number of pounds of apples that she has left will be 13/16 pounds.
