Answer:
Y is fairly simple to understand. Since theres a square on that angle, you can automatically tell that its a right angle. Right angles are angles that are 90 degrees, and are usually shaped like an L.
To determine the angle, we subtract 49 and 90 from 180, since the entire angle is leveled over a 180 plane.
180-49-90 = 41
X = 41 and y = 90.

es of two children are 11 and 8 years.
In how many years' time will the product of
The
their ages be 208?
Answers
Answer:
In 5 years the product of their ages will be 208
Step-by-step explanation:
The age of two children is 11 and 8 years.
Let's call x the number of years ahead.
We need to find when the product of their future ages is 208. The 11 years old child will be 11+x years old and the other child will be 8+x years, thus:
(11+x)(8+x)=208
Operating:
[tex]88+11x+8x+x^2=208[/tex]
Simplifying:
[tex]x^2+19x-120=0[/tex]
Factoring:
(x-5)(x+24)=0
Solving:
x=5, x=-24
The negative solution is not valid, thus x=5
In 5 years the product of their ages will be 208

Answers
Answer:
29) 60°
30) 80°
Step-by-step explanation:
29)
8x + 4 = 11 + 7x
x = 7
∴ ∠ = 11 + 7(7) = 60
30)
14x - 4 = 12x + 8
2x = 12
x = 6
∴ ∠ = 14(6) - 4 = 80
The point that is the reflection of D across the x-axis and the y-axis is point , and the coordinates of this point are . The reflection of point L across x-axis is point , and the coordinates of this point are .
Answers
Answer:
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).

Marissa is baking chocolate chip cookies. She has a total of 7 1/3 cups of chocolate chips. If each batch of cookies uses 2/3 of a cup of chocolate chips enter the greatest number of batches of cookies she can bake
Answers
Since 2/3 cup of chocolate chips = 1 batch
So 1/3 would = .5 (half a batch)
7 1/3 into a an improper fraction (just so it’s easier) = 22/3
In order to make 1/3 be 22/3 you would have to multiply 22 by 1/3
So you multiply 1/3 x 22 = 22/3
And you also multiply .5 x 22 = 11
So 22/3 (aka 7 1/3) serves 11 batches.

Ali, a seventh grade student, was asked to flip a penny 100 times and record how many tails and heads came up. Before doing the experiment, Ali predicted the probability of heads and tails to both be 0.5. When the experiment was complete Ali counted 77 tails and 23 heads.
1. Where Ali’s results consistent with her predictions? Explain your answer.
2. According to Ali’s experiment results, predict how many heads Ali would get if she were to flip the penny 200 times.
3. What would you expect to happen to the results the more times Ali flips the penny?
Answers
Answer:
1. No, 2. 46, 3. The amount of tails flips would be more than the amount of heads flips.
Step-by-step explanation:
1 is no because .77 and .23 are not equal to .5, so her prediction was wrong. 2 is 46 because if you double both the numbers (to get a total of 200 flips), you would get 154 tails and 46 heads. 3 is more tails than heads because that is what we have observed.

You need to multiply both by the same number, so it is proportional.
9514 1404 393
Answer:
60 mph, or 4 h
Step-by-step explanation:
In the relationship between distance, speed, and time, we find that distance is jointly proportional to speed and time. That means, the equation of proportionality can be written two ways:
distance = speed × time
distance = (60 mph) × time . . . . . 60 mph is the constant of proportionality
or ...
distance = time × speed
distance = (4 h) × speed . . . . . 4 h is the constant of proportionality
__
Usually, we take time to be the independent variable, so the first version applies. However, the second version is also a legitimate answer.

You borrow $2500 to buy a new riding mower. The simple interest rate is 6%. You pay the loan off after 3 years. What is the total amount you payed for the loan?
Answers
Answer:
$2950
Step-by-step explanation:
The equation for simple interest is A = P (1 * rt) where A is the final amount, P is the principal or initial amount, r is the rate, and t is the time.
In this problem, P = $2500, the rate is 6% so r = 0.06, and t = 3. Filling in the equation, you get A = 2500 (1 + 0.06*3).
This should come out to A = $2950.

Determine the angle between the two lines with equations 4x - 5y = 11 and 2x + 3y = 7.
Answers
Answer:
The angle between the two lines is 72.35° ⇒ to the nearest hundredth
Step-by-step explanation:
The angle between the two lines is the difference between their angles with the positive part of the x-axis (Ф = Ф[tex]_{2}[/tex] - Ф[tex]_{1}[/tex]) The slope of the line equal to the tangent of the angle between the line and the positive part of the x-axis (m = tan Ф)The slope of the line whose equation is ax + by = c is m = [tex]\frac{-a}{b}[/tex]∵ The equation of the first line is 4x - 5y = 11
∴ a = 4 and b = -5
→ By using the 3rd rule of the slope above
∵ m[tex]_{1}[/tex] = [tex]\frac{-4}{-5}[/tex] = [tex]\frac{4}{5}[/tex]
∴ m[tex]_{1}[/tex] = 0.8
→ By using the 2nd rule above
∵ tan Ф[tex]_{1}[/tex] = 0.8
∴ Ф[tex]_{1}[/tex] = [tex]tan^{-1}[/tex](0.8)
∴ Ф[tex]_{1}[/tex] = 38.66° ⇒ to the nearest hundredth
∵ The equation of the first line is 2x + 3y = 7
∴ a = 2 and b = 3
→ By using the 3rd rule of the slope above
∵ m[tex]_{2}[/tex] = [tex]\frac{-2}{3}[/tex]
∴ m[tex]_{2}[/tex] = [tex]-\frac{2}{3}[/tex]
→ By using the 2nd rule above
∵ tan Ф[tex]_{2}[/tex] = [tex]-\frac{2}{3}[/tex]
∴ Ф[tex]_{2}[/tex] = [tex]tan^{-1}[/tex]( [tex]-\frac{2}{3}[/tex])
∴ Ф[tex]_{2}[/tex] = -33.69° ⇒ to the nearest hundredth
→ By using the 1st rule above
∵ Ф = -33.69 - 38.66
∴ Ф = -72.35°
→ Ignore the negative sign
∴ The angle between the two lines is 72.35° ⇒ to the nearest hundredth
V.I.N:
You can use this rule to find the angle between 2 lines tan Ф = I[tex]\frac{m_{2}-m_{1}}{1+m_{1}.m_{2}}[/tex]I

Answers
Answer:
The point-slope form of the equation is:
[tex]y-\left(-5\right)=-3\left(x-3\right)[/tex]Step-by-step explanation:
Given
point (3, -5)slope = -3We know the point-slope form of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values m = -3 and the point (3, -5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-5\right)=-3\left(x-3\right)[/tex]
