Answer:
2 three points shots and 4 two points shots
Step-by-step explanation:
Let x be the number of three points shots.
Alexander made twice as many two points shots as three points shots, so the number of two points shots is 2x.
Amount earned in three points shots [tex]=3\cdot x[/tex]
Amount earned in two points shots [tex]=2\cdot (2x)=4x[/tex]
Total score [tex]=3x+4x=7x[/tex]
Alexander scores a total of 14 points, then
[tex]7x=14\\ \\x=2\\ \\2x=2\cdot 2=4[/tex]
Triangle A B C is shown with its exterior angles. Angle B A C is (p + 4) degrees and angle A C B is 84 degrees. Exterior angle X B C is (3 p minus 6 degrees).
What is the measure of ∠XBC?
m∠XBC = m∠BAC + m∠BCA
3p – 6 = p + 4 + 84
3p – 6 = p + 88
2p – 6 = 88
2p = 94
Answer:
The diagram of the question is attached here.
The measure of [tex]\angle XBC=135\ (deg)[/tex]
Step-by-step explanation:
All the options given here will be used to find the numeric value of [tex]\angle XBC[/tex]
Here it is shown systematically.
Exterior angle theorem: Sum of two interior angles are equal to the measure of opposite exterior angle in a triangle.
To find [tex]\angle XBC[/tex]
[tex]m\angle XBC = m\angle BAC + m\angle BCA[/tex]
Plugging the values.
[tex]3p-6 = p + 4 + (84)[/tex]
[tex]3p-6 = p + 88[/tex]
Subtracting [tex]p[/tex] both sides.
[tex]2p-6 = 88[/tex]
[tex]2p = 94[/tex]
Dividing [tex]2[/tex] both sides.
[tex]p=\frac{94}{2}=47[/tex]
So plugging the value of [tex]p=47[/tex] in [tex]3p-6[/tex] we will get the measure of [tex]\angle XBC[/tex].
So [tex]\angle XBC=(3p-6)=3(47)-6=135\ (deg)[/tex]
The measure of [tex]\angle XBC[/tex] is [tex]135\ degrees[/tex].
Based on the information, the measure of Angle XBC is 278 - 4p degrees.
What's the measurements?Given that Angle ACB is 84 degrees, Angle BAC is (p + 4) degrees, and Angle XBC is (3p - 6) degrees, you can plug in these values:
(p + 4) + 84 + (3p - 6) + Angle XBC = 360
Combine the like terms involving 'p':
4p + 82 + Angle XBC = 360
Subtract 82 from both sides:
4p + Angle XBC = 278
Now, isolate Angle XBC by subtracting 4p from both sides:
Angle XBC = 278 - 4p
So, the measure of Angle XBC is 278 - 4p degrees.

Consider the following equations: f(x) = 2x – 2 and g(x) = 5 - x
a. The two equations represent lines on a graph, describe the difference in slope and y-intercept.
Answer:
The difference in slopes of [tex]f(x)\ and\ g(x)[/tex] is = 3
We can say slope of [tex]f(x)[/tex] is positive and 3 more than slope of [tex]g(x)[/tex] while slope of [tex]g(x)[/tex] is negative.
Difference of y-intercepts of [tex]f(x)\ and\ g(x)[/tex] is = -7
We can say the y-intercept of [tex]g(x)[/tex] is positive and 7 units above [tex]f(x)[/tex] while y-intercept of [tex]f(x)[/tex] is negative.
Step-by-step explanation:
Given equation:
[tex]f(x) =2x - 2[/tex]
[tex]g(x) =5-x[/tex]
We need to find the difference of slopes and y-intercepts of the given equations.
The standard form of a slope intercept equation of line is given by:
[tex]y=mx+b[/tex]
where [tex]m[/tex] represents slope and [tex]b[/tex] represents y-intercept of line.
Writing the given equations in standard form to find slope and y-intercept.
[tex]f(x) =2x +(-2)[/tex]
Slope = 2 and y-intercept =-2
[tex]g(x) =(-1)x+5[/tex]
Slope = -1 and y-intercept =5
The difference in slopes of [tex]f(x)\ and\ g(x)[/tex] is = [tex]2-(-1)=2+1=3[/tex]
We can say slope of [tex]f(x)[/tex] is positive and 3 more than slope of [tex]g(x)[/tex] while slope of [tex]g(x)[/tex] is negative.
Difference of y-intercepts of [tex]f(x)\ and\ g(x)[/tex] is = [tex]-2-5=-7[/tex]
We can say the y-intercept of [tex]g(x)[/tex] is positive and 7 units above [tex]f(x)[/tex] while y-intercept of [tex]f(x)[/tex] is negative.

after using six mushrooms to boost their speed. marcus racer has travelled 650 feet. hiw far did marcus racer travel after using three mishrooms?
Answer: 325 ft
Step-by-step explanation:
6 mushrooms = 650 ft
divide by 2 on both sides
3 mushrooms = 325 ft
5 mushrooms = 6-1 mushrooms
5 mushrooms = 650 - (boost distance for 1 mushroom)
1 mushroom = 650/6 = 108.3 repeating
so 5 mushrooms = 650 - 108.333333333 = 542.66666666
Write the equation of the line that is parallel to y=-0.75x and that passes through the point (8,0)
The equation of the line that is parallel to y=-0.75x and passes through the point (8,0) is y = -0.75x + 6.
Explanation:The equation of a line in the form y = mx + b represents a linear equation, where m is the slope of the line and b is the y-intercept. Since we are looking for a line parallel to y = -0.75x, we know that the new line will have the same slope. So, the equation of the new line is y = -0.75x + b. To find the value of b, we can substitute the coordinates of the point (8,0) into the equation and solve for b.
0 = -0.75(8) + b
0 = -6 + b
b = 6
Therefore, the equation of the line that is parallel to y = -0.75x and passes through the point (8,0) is y = -0.75x + 6.
The average weight of a watermelon is 4.61 kg. The average weight of a coconut is 2.22 kg less than a watermelon. The total weight of an equal number of coconuts and watermelons is 140 kg. How many coconuts are there?
Since the average weight of a coconut is 2.22 kg less than a watermelon, its average weight is
[tex]4.61-2.22=2.39[/tex]Let n be the number of coconuts and watermelons. The total weight of n coconuts and n watermelons is
[tex]4.61n+2.39n = 7n[/tex]
If we want this total to be 140, we have
[tex]7n=140 \iff n=\dfrac{140}{7}=20[/tex]
So, you have 20 coconuts and 20 watermelons.
Final answer:
To find the number of coconuts, we can set up an equation using the given information. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon. By setting up the equation x(4.61 + 2.39) = 140 and solving for x, we find that there are 20 coconuts.
Explanation:
To solve this problem, we need to set up equations using the given information. Let's represent the number of coconuts as 'x'. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon, which means it is 4.61 - 2.22 = 2.39 kg. Since the number of coconuts and watermelons is equal, we can write the equation: x(4.61 + 2.39) = 140. Solving this equation, we get 7x = 140, which means x = 140/7 = 20.
Therefore, there are 20 coconuts.

How to solve : 16=2t + 0.25 t``squar
Answer:
The solutions of the equation are t = 4(√5 + 1) or 4(√5 - 1).
Step-by-step explanation:
We have to solve the given quadratic equation of single variable t.
The equation is 16 = 2t + 0.25t²
⇒ 0.25t² + 2t - 16 = 0
⇒ 25t² + 200t - 1600 = 0 {Multiplying both sides with 100}
⇒ 25t² + 200t + 400 - 400 - 1600 = 0
⇒ (5t + 20)² - 2000 = 0
⇒ (5t + 20)² - (20√5)² = 0
⇒ (5t + 20 + 20√5)(5t + 20 - 20√5) = 0
So, (5t + 20 + 20√5) = 0 or, (5t + 20 - 20√5) = 0
⇒ (t + 4 + 4√5) = 0 or, (t + 4 - 4√5) = 0
⇒ t = - 4(1 + √5) or, t = 4(√5 - 1) (Answer)

What is the simplified form of StartRoot StartFraction 48 Over 192 EndFraction EndRoot? One-fourth One-half 2 4
Answer:
1/2 or B on edge
Step-by-step explanation:
If one were to simplify the fraction 48 / 192, the result they would get is the fraction 1/4 or One-fourth
When taking a fraction to its simplest form, you divide both the numerator and the denominator by their greatest common factor.
The greatest common factor of both numbers is 48.
The simplest form is therefore:
= (48 ÷ 48) / (192 ÷ 48)
= 1 / 4

A fireworks rocket is launched from a hill above a lake. The rocket will fall into the lake after exploding at its maximum height. The rocket's height above the surface of the lake is given by g(x)= -16x^2+64+80. What is the maximum height of the rocket?
A) 150 feet C) 120 feet
B) 80 feet D) 144 feet
Answer:
D
Step-by-step explanation:
At the maximum height, the value of the vertical velocity Vy equals zero. From the value of the equation, we can get the vertical velocity by its first differential.
Differentiating this, we get -32x + 64
We then equate this value to zero. This yield 32x = 64 and x = 2
We now plug the value of x back into the original expression for height.
-16(2)^2 + 64(2) + 80 = -64 + 128 + 80 = 144 feet
