Solve the following equation for x: (2/3)x = 10 *
x = 8
x = 5
x = 15
x = 30
Answer:
the answer is x=15
I am sure
Answer:
x = 15
Step-by-step explanation:
(2/3)x = 10
(2/3x) * 3 = 10 * 3
2x ÷ 2 = 30 ÷ 2
x = 15

On a windless day In Janurafy, Carl ties 300 helium filled balloons to his lawn chair 80ft from his 20ft tall house, and begins a vergical ascent into the sky. Hos high is carl when the angle lf depression from carl to the top of his house is 42°
Answer:
The answer is below
Step-by-step explanation:
θ = 90° - 42° = 48°
The angle formed is a right angled triangle, therefore trigonometric identities can be used to find the length of the triangle sides.
tan(θ) = opposite / adjacent
tan(48) = 80 / h
h = 80 / tan(48)
h = 72.03 ft
h is the vertical distance from carl to the top of his house, to get his total height to the ground (H), we use:
H = h + height of house
H = 72.03 + 20
H = 92.03 ft
Therefore Carl is 92.03 ft high

Suppose a constellation of stars is plotted on a coordinate plane. The coordinates of the first star are (–2, 4). The second star is translated down 4 units. What are the new coordinates?
Answer:
Coords (-2,0)
Step-by-step explanation:
Translation means moving the point in the direction that is stated by the amount stated. Down means decreasing the number value along the y-intercept. So using simple math subtract 4 by 4 and you get 0. Since we don't move the left or right which means going along the x-intercept lines. We get (-2,0)
Abby has a collection of 61 dimes and nickels worth $4.40.How many nickels does she have?
9514 1404 393
Answer:
34
Step-by-step explanation:
Let x represent the number of nickels Abby has. Then the number of dimes is 61-x. The total value of the coins, in cents, is ...
5x +10(61-x) = 440
-5x +610 = 440 . . . . . simplify
x - 122 = -88 . . . . . . . .divide by -5
x = 34 . . . . . . . . . . . . add 122
Abby has 34 nickels in her collection of coins.
A linear sequence starts a + 2b, a + 6b, a+10b
The 2nd term has value 8 and the 5th has value 44
Work out the values of a and b
Answer:
a = -12
b = 3
Step-by-step explanation:
second term = a + 6b
to find the 5th term, notice the pattern (since this is a linear equation, each term increases by the same amount) and each term increases by 4b: 2b -> 6b -> 10b.
therefore, the 4th term would be a+14b and the 5th would be a+18b
so a + 6b = 8
and a + 18b = 44
u now have two simultaneous equations, which can be solved through substitution or elimination. I'm gonna use elimination because it's quicker in this case:
[tex]a + 6b = 8\\- (a + 18b = 44)\\ -12b = -36\\b = 3[/tex]
steps: (since the a would cancel out by subtracting, subtract then solve for b. divide by -12 on both sides to isolate the b)
now that u know the value of b, substitute it into an equation to solve for a:
a + 6b = 8
a + 6(3) = 8
a + 24 = 8
a = 8 - 24
a = -16
hope this helps!
Heng tried to define a reflection across line r.
Any point M not on the line of reflection maps to a point M' such that the midpoint L of M→M' is on line r.
Which counterexample shows that Heng's definition does not fully define a reflection?
The counterexample shows that Heng's definition does not fully define a reflection is Heny fully defined a reflection. Option D
How to determine the counterexampleConsider the counterexample in which point M is above line r and the line itself is a vertical line.
Assume M is located at (0, 2) and that line r is the x = 1 line. Heng's definition states that point M', which has a midpoint L that is on line r, should reflect point M across line r.
However, point M' at (-1, 2) would be the reflection of point M across line r, which does not meet the requirement that the midpoint L lies on line r. Therefore, in this counterexample, Heng's definition does not adequately characterize a reflection.

(Sat prep) find the value of x, 65 degrees and 75 degrees isosceles triangle.
Answer:
x = 40°Step-by-step explanation:
The triangle is not isosceles
The angles of the triangles are:
65°, 75° and x for both of the bigger and the smaller trianglesThe interior angles of a triangle sum to 180
x = 180° - (65° + 75°)x = 180° - 140°x = 40°There is a 10% chance of rain tomorrow. A spinner with 10 sections is spun to simulate the probability of rain. If the results are 3, 6, 1, 8, and 3, then what is the difference in the experimental probability from the simulation and the prediction?
Answer:
On the simulation prediction you got a 10% chance
While in the experimental one the average is 42%

Jose rents a bike for $4 plus
$2.50 per hour. Elaine rents a
moped for $10 plus $1 per
hour. Write and solve the
system of equations to
determine at what point they
spend the same amount.
Answer:
4 hours
Step-by-step explanation:
Step One: Define Variables -Let x be the # of hours spent using the vehicles
Step Two: Make Equations -Jose: 4 + 2.5x
Elaine: 10 + x
Step Three: Solve -If they spend the same amount then that means:
Elaine's price = Jose's price, therefore:
4 + 2.5x = 10 + x
1.5x = 6
x = 4
At 4 hours, both prices are the same.
Answer:
They spend the same amount after 4 hours
1 of 9 3 7 of students at a school are boys. If there are 2282 students at the school, how many are girls?
Answer: 1304
Step-by-step explanation:
Fraction of the boys = 3/7
Fraction of the girls = 1 - 3/7 = 4/7
Number of students = 2282
The number of girls will be:
= Fraction of girls × Total number if students
= 4/7 × 2282
= 1304
There are 1304 girls
5, 7, 7, 8, 10, 11, 12, 15, 17. Q1 = 7, Q2 = 11, Q3 = 15 Q1 = 7, Q2 = 10, Q3 = 13.5 Q1 = 6, Q2 = 9, Q3 = 12 Q1 = 7.5, Q2 = 10.5, Q3 = 13.5
Answer:
[tex]Q_1 = 7[/tex]
[tex]Q_2 = 10[/tex]
[tex]Q_3 = 13.5[/tex]
Step-by-step explanation:
Given
5, 7, 7, 8, 10, 11, 12, 15, 17.
Required
Determine Q1, Q2 and Q3
The number of data is 9
Calculating Q1:
Q1 is calculated as:
[tex]Q_1 = \frac{1}{4}(N + 1)[/tex]
Substitute 9 for N
[tex]Q_1 = \frac{1}{4}(9 + 1)[/tex]
[tex]Q_1 = \frac{1}{4}*10[/tex]
[tex]Q_1 = 2.5th\ item[/tex]
This means that the Q1 is the mean of the 2nd and 3rd data.
So:
[tex]Q_1 = \frac{1}{2}(7+7)[/tex]
[tex]Q_1 = \frac{1}{2}*14[/tex]
[tex]Q_1 = 7[/tex]
Calculating Q2:
Q2 is calculated as:
[tex]Q_2 = \frac{1}{2}(N + 1)[/tex]
Substitute 9 for N
[tex]Q_2 = \frac{1}{2}(9 + 1)[/tex]
[tex]Q_2 = \frac{1}{2}*10[/tex]
[tex]Q_2 = 5th\ item[/tex]
[tex]Q_2 = 10[/tex]
Calculating Q3:
Q3 is calculated as:
[tex]Q_3 = \frac{3}{4}(N + 1)[/tex]
Substitute 9 for N
[tex]Q_3 = \frac{3}{4}(9 + 1)[/tex]
[tex]Q_3 = \frac{3}{4}*10[/tex]
[tex]Q_3 = 7.5th\ item[/tex]
This means that the Q3 is the mean of the 7th and 8th data.
So:
[tex]Q_3 = \frac{1}{2}(12+15)[/tex]
[tex]Q_3 = \frac{1}{2}*27[/tex]
[tex]Q_3 = 13.5[/tex]

Find an expression which represents the difference when (6x-3y) is subtracted from (9x+2y) in simplest terms.
Answer:
[tex]3x+5y[/tex]
Step-by-step explanation:
Subtract (6x-3y) from (9x+2y):
[tex](9x+2y)-(6x-3y)[/tex]
This can also be seen as:
[tex](9x+2y)-1(6x-3y)[/tex]
Distribute the -1 to (6x-3y):
[tex](9x+2y)-1(6x)-1(-3y)\\\\(9x+2y)-6x+3y[/tex]
Simplify the parentheses:
[tex]9x+2y-6x+3y[/tex]
Group like terms:
[tex](9x-6x)+(2y+3y)[/tex]
Combine:
[tex]3x+5y[/tex]
This expression can't be further simplified. Therefore, 3x+5y is the answer.

Using The graph below identify the axis of symmetry for the parabola below 
Answer:
x=-3
Step-by-step explanation:
The axis of symmetry is the line that separates a parabola directly in half. It is measure on x axis because it is being split in terms of that number. Next, you identify the origin and find exactly where the parabola is in half and that is your answer. Another way to do this would be to identify the vertex of the parabola. The answer is the x coordinate of the location of the vertex. (The highest point of a parabola.)
Does the line passing through the points (3,3) and (7,11) intersect the line passing through the points (5,8) and 13,24) ?
Answer:
no they don't intersect
Step-by-step explanation:
line 1:
m=11-3/7-3=8/4=2
y-3=2(x-3)
y-3=2x-6
y=2x-3
line 2:
m=24-8/13-5=16/8=2
y-8=2(x-5)
y-8=2x-10
y=2x-2
no they don't intersect cause they are parallel and parallel lines don't cross
A person who is 6 feet tall is standing 120 feet from the base of a tree, and the tree casts a 130 foot shadow. The person's shadow is 10 feet in length. What is the height of the tree?
Answer:
the tree is 65 feet high.
Step-by-step explanation:
let 'x' be the height of the tree
draw the tree, the person and the shadows - notice the similar triangles
the following proportion counts
x : 5 = 130 : 10
x = (5*130)/10
x = 65 feet
