Answer:
77
Step-by-step explanation:
180-61-42
Answer:
x = 77°
Step-by-step explanation:
the total among these angles are 180° so add 61 + 42 which equals 103 then subtract it from the total
180° - 103° = 77°
x = 77°

Answer:
What is the slope of the line that represents the turtle's path?
=0.8
What are the values of the constants in the vertex form of the quadratic equation that models the bird's path?
h=0
k=20
a= -0.12
Which system of equations could you use to determine where the paths intersect?
=B) y = 0.8x and y = -0.12x2 + 20
Step-by-step explanation:
your welcome <3
Based on the graph, the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.How to write a function.Generally, the vertex form of a quadratic equation can be used to model or write an equation of the function of a graph.
Mathematically, the vertex form of a quadratic equation is given by this formula:
y = a(x - h)² + k
Where:
h and k represents the vertex of the graph.
Note: The sign on "a" indicates whether the quadratic equation opens up or opens down.
Based on the complete information, we can deduce that the values of the constants in the vertex form of the quadratic equation are:
h = 0.k = 20.a = -0.12.Read more on vertex here: brainly.com/question/525947

A. What is the sum of all the interior angles in the kite?
B. Copy the kite and draw the diagonals. What is the measure of the angle at which the diagonals intersect?
Answer:
A. 360 degrees
B. 360 degrees all the way around but each individual one is 90 degress
Step-by-step explanation:
Answer:
Step-by-step explanation:
B: the kite's diagonals intersect each other at a 90o degree angle.
A: It should come to 360. Let's if that happens.
Take the top angle (88) first. Notice that if you draw in both diagonals, the will form Isosceles triangles. Let's deal with the shorter diagonal first.
The two angles at the base of the shorter diagonal are equal. That's because the sides opposite them are equal.
2x +88 = 180 Subtract 88 from both sides.
2x = 92 Divide by 2
x = 46
Now lets look at the long narrow legs of the bottom isosceles triangle.
2x + 50 = 180 Subtract 50 from both sides
2x = 130 divide by 2
x = 130 /2
x = 65
Now add up all the angles that make up the interior of the kite.
Total = 46 + 46 + 65 + 65 + 50 + 88
Total = 360 just as it should.
Solve for x. Round to the nearest tenth of a degree, if necessary. Answer:x =
Please respond quick
Answer:
x = 61.6 degree
Step-by-step explanation:
take x degree as reference angle
using sin rule
sin x = opposite / hypotenuse
sin x = 4.8 / 5.4
sin x = 0.88
x = [tex]sin^{-1} (0.88)[/tex]
x = 61.64
x = 61.6 degree
Anyone know how to factorise this please ?! :)
9514 1404 393
Answer:
a) (x +2)(x +3)
b) x = -2 or -3
Step-by-step explanation:
a) The constants in the binomial factors will be divisors of 6 that have a sum of 5. You know that ...
6 = 1×6 = 2×3
The sums of these factor pairs are 7 and 5. You want the pair 2, 3. The factors are ...
x² +5x +6 = (x +2)(x +3)
__
b) The solutions to the equation are the values of x that make the factors zero:
(x +2) = 0 ⇒ x = -2
(x +3) = 0 ⇒ x = -3

the sum of five consecutive numbers is 700, what is the first number?
Answer:
The first number is 138.
Step-by-step explanation:
Let the first number be x.
Then since they are consecutive numbers, the second number will be (x + 1), the third (x + 2), the fourth (x + 3) and the fifth being (x + 4).
We are given that their sum is 700. Therefore:
[tex]x+(x+1)+(x+2)+(x+3)+(x+4)=700[/tex]
Solve for x. Combine like terms:
[tex]5x+10=700[/tex]
Subtract 10 from both sides:
[tex]5x=690[/tex]
Divide both sides by five. Therefore:
[tex]x=138[/tex]
The first number is 138.
Answer:
138
Step-by-step explanation:
(n) + (n+1) + (n+2) + (n+3) + (n+4) = 700
5n + 10 = 700
5n = 690
n = 138

Carl can paint a room 3 hours faster than Jennifer can. If they work together, they can complete the job in 2 hours. Using complete sentences, explain each step in figuring out how to determine the time it would take Jennifer to complete this job on her ow
Answer:
If they would both work at the same speed they would each take 4 hours to complete the room. So in total they would work 8 hours. But because Carl can finish three hours before Jennifer 3 hours of the eight already got to Jennifer. Then we divide the resting 5 hours by the two and then we have:
Jennifer:
3+2,5=5,5
Carl:
2,5

If the coordinates are (0, a) and (b, 0), we just use the distance formula to find the distance in terms of a and b:
[tex]d=\sqrt{(0-a)^2+(b-0)^2}[/tex] and
[tex]d=\sqrt{(-a)^2+b^2}[/tex] which simplifies to

According to a survey, about 30% of people ages 18 and older in a city have a cat. You ask 5 randomly chosen people (ages 18 and older) whether they have a cat. What is the probability that at least 2 people have a cat? Round your answer to the nearest hundredth.
Step-by-step explanation:
When they ask what the prob that at most 3/4 people asked have a pet, they are asking what is the prob that 0, 1, 2, or 3 people answer yes. So you could calculate all 4 of those and then add them together.
However, in this case, since there's only 1 other possible outcome (all 4 have a pet), we could just calculate the prob of that and subtract it from 1 to get the prob of everything else happening.
We'll use the binomial distribution formula where n=4, k=4, and P=.6.
nCk * P^n * (1-P)^(n-k)4C4 * (.6)^4 * (.4)^0.1296
So the prob of at least 3 having pets = 1 - P(all 4 have pets) which is 1-.1296 = .8704. You could double check this by calculating the prob of the other 4 outcomes and then adding them together.
The probability that at least 2 people have a cat is 0.522 or 52.2%.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
This is a problem that can be solved using the binomial probability formula, which gives the probability of getting exactly k successes (in this case, people with cats) out of n trials (in this case, people you ask) with a probability of success (in this case, having a cat) of p.
The formula is:
P(k) = (n choose k) × [tex]p^k \times (1-p)^{(n-k)}[/tex]
where (n choose k) is the binomial coefficient, which is equal to n! / (k! × (n-k)!).
For this problem, n = 5 (the number of people you ask), k = 2 (the number of people who have cats), and p = 0.3 (the probability of a person having a cat, according to the survey).
P(2) = (5 choose 2) × 0.3² × 0.7³
P(2) = 0.252
To find the probability of at least 2 people having a cat, we have to add up the probability of getting exactly 2, 3, 4, and 5 people having cats.
P(≥2) = P(2) + P(3) + P(4) + P(5)
Substituting the values we get:
P(≥2) = 0.252 + 0.189 + 0.072 + 0.009 = 0.522
So, the probability that at least 2 people have a cat is 0.522 or 52.2%.

Mercury is at a distance of 46213267 km from the sun. If the value of this area is rounded off to the nearest one hundred, then the result would be .
Answer:
46,213,300 km
Step-by-step explanation:
46,213,267
in the above number ;
7 = units
6 = tens
2 = hundred
3 = thousand
1 = ten thousand
2 = hundred thousand
6 = million
4 = 10 million
to round off to the nearest hundred, look at the number in the tens (6). If this number is greater than or equal to 5, add 1 to the hundreds unit, if this is not the case, add zero
because 6 is greater than 5, add one to the hundred value
= 46,213,300 km
