Answers
Answer:
Step-by-step explanation:
1)
First we add what we know for y into the second equation.
5x - 4(x +2)= -3
From there, we simplify it
5x-4x-8= -3
x-8=-3
Now we get the x on its own
x=5
and now we add x=5 into the first equation that we had and simplify to find y
y=5+2
y=7
So the answer is x=5, y=7 or (5,7)
2)
For this one we do the same thing as with 1.
Add what we know for y (bottom equation) to the top equation
3x-8(x-8)=24
Now we simplify
3x-8x+64=24
-5x+64=24
And now solve for X
-5x=-40
x=8
And then substitute x=8 to find y
y=8=8
y=0
So the answer is x=8, y=0 or (8,0)

an astronaut drops a rock off the edge of a cliff on the moon. the distance, d(t), in meters, the rock travels after t seconds can be modeled by the function d(t) = 0.8t^2. what is the average speed, in meters per second, of the rock between 5 & 10 seconds after it was dropped?
Answers
Answer:
The average speed between the times given is 12 m/s
Step-by-step explanation:
Here, we want to calculate rate of change between the times given
Mathematically , we can get the average rate of change using the formula
f(b)-f(a)/b-a
in this case, b = 10 s and a = 5 s
f(b) is d(10) = 0.8(10)^2 = 80
f(a) is d(5) = 0.8(5)^2 = 20
Rate of change is thus;
(80-20)/(10-5) = 60/5 = 12 m/s

Find the measure of angle K.
Answers
Answer:
m∠K = 97°
Step-by-step explanation:
The sum of the measures of the angles of a quadrilateral is 360
127 + 5x + 3 + 10x + 7 + 88 = 360
15x + 225 = 360
15x = 135
x = 9
m∠K = 10x + 7 = 10(9) + 7 = 90 + 7 = 97°

Answers
The probability of getting a 6 and any color except a shade of blue is 2/15.
The probability of getting a 5 and a shade of blue is 1/30.
The probability of getting an even number and a shade of blue is 1/10.
The probability of getting at least 3 and any color except a shade of blue is 4/15.
The probability of getting at most 4 and yellow is 2/15.
We have,
The probability of getting a 6 and any color except a shade of blue:
This probability involves rolling a 6 on the die and getting any color except a shade of blue on the spinner.
Since the die has six equally likely outcomes and the spinner has four colors that are not shades of blue, the probability is (1/6) x (4/5) = 2/15.
The probability of getting a 5 and a shade of blue:
This probability involves rolling a 5 on the die and getting a shade of blue on the spinner.
Since the die has six equally likely outcomes and the spinner has one shade of blue section, the probability is (1/6) x (1/5) = 1/30.
The probability of getting an even number and a shade of blue:
This probability involves rolling an even number (2, 4, or 6) on the die and getting a shade of blue on the spinner.
Since the die has three even numbers and six equally likely outcomes, and the spinner has one shade of blue section, the probability is (3/6) x (1/5) = 1/10.
The probability of getting at least 3 and any color except a shade of blue:
This probability involves rolling a number greater than or equal to 3 on the die and getting any color except a shade of blue on the spinner.
Since the die has four outcomes (3, 4, 5, or 6) that satisfy this condition, and the spinner has four colors that are not shades of blue, the probability is (4/6) x (4/5) = 4/15.
The probability of getting at most 4 and yellow:
This probability involves rolling a number less than or equal to 4 on the die and getting yellow on the spinner.
Since the die has four outcomes (1, 2, 3, or 4) that satisfy this condition, and the spinner has one yellow section, the probability is (4/6) x (1/5) = 2/15.
Thus,
The probability of getting a 6 and any color except a shade of blue is 2/15.
The probability of getting a 5 and a shade of blue is 1/30.
The probability of getting an even number and a shade of blue is 1/10.
The probability of getting at least 3 and any color except a shade of blue is 4/15.
The probability of getting at most 4 and yellow is 2/15.

Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let us consider x years later it would reach 40 million.
So, 39.1 + 0.35 x = 40
0.35x= 40- 39.1
0.35x= 0.9
x= 2.57
x= 3 years
Hence, In 2018 the population will reach 40 million.

You already have an angle that measures 34 degrees.
Alternate interior angles are congruent. So, the given angle is equal to m<b.
Now add 90+34=124
To get the alternate interior angles (m<a and m<c) subtract 124 from 180 which equals 56 degrees.

Step-by-step explanation:
When two chords intersect at a point in a circle, they form arcs, along with angles at the intersection point.
To determine the angle of the arc, we must apply this geometric rule:
[tex] Angle \: formed \: by \: chords = \frac{1}{2}(sum \: of \: intersecting \: arcs) [/tex].
Since we are looking for one of the arcs, we can rearrange this formula to solve for the first arc.
[tex] Angle \: formed \: by \: chords = \frac{1}{2}(sum \: of \: intersecting \: arcs) [/tex] →
[tex] Angle \: formed \: by \: chords = \frac{1}{2}(\overset{\frown}{BA} + \overset{\frown}{CD}) [/tex] →
[tex] 2 × Angle \: formed \: by \: chords = \overset{\frown}{BA} + \overset{\frown}{CD} [/tex] →
[tex] 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} = \overset{\frown}{BA} [/tex]
[tex] \overset{\frown}{BA} = 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} [/tex]
[Given]
[tex] \overset{\frown}{BA} = x° [/tex]
[tex] \overset{\frown}{CD} = 99° [/tex]
[tex] Angle \: formed \: by \: chords \: = 72° [/tex]
→
[tex] \overset{\frown}{BA} = 2 × Angle \: formed \: by \: chords \: – \: \overset{\frown}{CD} [/tex]
→
[tex] x° = 2 × 72° \: – \: 99° [/tex]
[tex] x° = (2 × 72°) \: – \: 99° [/tex]
[tex] x° = 144° \: – \: 99° [/tex]
[tex] \boxed{x° = 45°} [/tex]
