The picture shows a carousel. The carousel spins while the horses move up and down. A student determines to
each horse completes one up-down cycle in 30 seconds. The student rides a horse on the carousel for 2 minute
which equals 120 seconds.
raal
Answer:
4 times
Step-by-step explanation:
Note,
60 seconds = 1 minute120 seconds = 2 minutes (60*2).Since the student rode a horse for 120 seconds, to find the number of times the student riding the carousel completed the up-down cycle, we divide it by 30 seconds (which is the duration for the horse to complete one up-down cycle) because the student would be having the same duration as the horse because he was on top the horse.
Hence, we have;
120/30 = 4
If 40% of a number is 28, find 10% of that number.

Determine if each statement is True or False. If False, determine what needs to be
changed to make the statement True.
a. In 5x - 8,5 is the constant.
b. In x - 6.5, x is the variable.
C. In 9y + 38, 38 is the constant.
Answer:
a. False. A constant is a number on it's own, and 5 would be the coefficient of x. 8 would be the constant.
b. False. -6.5 would be the constant, since it's on its own. But actually, x would be carrying on a coefficient of 1. Letters are variables, not constants.
c. True.
George drove 240 miles to his grandmother's house. The graph below shows the relationship between the distance he traveled and time.
What does the slope of the graph represent?
A.
The total distance he has traveled.
B.
George's speed in minutes per mile.
C.
George's speed in miles per minute.
D.
The total distance he has left to travel.
plz get it right
Answer:
There is no graph but I can infer that if time is on the x axis it would be C and if distance is on the x axis it would be B
Step-by-step explanation:
The point (-4, 6) is a solution to which of the following system of
inequalities?
x + 2y > 8 and - 4x – y > 10
x + 2y < 8 and - 4x - y = 10
x + 2y = 8 and - 4x - y s 10
x + 2y = 8 and - 4x – y < 10
Answer:
x + 2y < 8 and - 4x -y = 10
Step-by-step explanation:
make x the subject of the formula then collect like terms then subtract and make them cross the equally sign
The given point (-4, 6) is the solution of the system of equations x + 2y = 8 and - 4x - y = 10. Option C is correct.
Gvien that,
To determine the system of inequality and equation where point (-4, 6) lies.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
here,
= x + 2y
where x = -4 and y = 6
= -4 + 12
= 8
So it matches with the equation given in option C
Now,
=-4x - y
Substitute the point
= -4 × -4 - 6
= 16 - 6
= 10
So it matches with the equation given in option C
Thus, the given point (-4, 6) is the solution of the system of equations x + 2y = 8 and - 4x - y = 10. Option C is correct.

Suppose one serving of Vegetables is 3/4 cup. How many servings are there in 35 cups?
9514 1404 393
Answer:
46
Step-by-step explanation:
The number of servings is ...
(35 cups)/(3/4 cup/serving) = (4/3)(35) servings = 46 2/3 servings
There are 46 full servings of Vegetables in 35 cups.

what does b equal b=____
9514 1404 393
Answer:
b = 90°
Step-by-step explanation:
Angles a, b, c form a linear angle, so their sum is 180°. This means ...
a + b + c = 180°
b = 180° -(a +c)
Angles 'a' and 'c' are complementary, so their sum is 90°.
b = 180° -90°
b = 90°
__
We can also find the measures of the other angles in this geometry.
a = 90° -c = 90° -56° = 34°
e = c = 56° . . . . . . . . . vertical angles
In summary, ...
a = 34°, b = 90°, c = 56°, d = 124°, e = 56°

Step-by-step explanation:
Flight 101, headed straight north, climbed to 30,000 feet and started its cruising speed of 360 mph 10 miles south of the point directly above our location. Flight 222, headed straight west, already cruising at 30,000 feet at 300 mph, was 5 miles east of the point above us at that time. Clearly, the paths of the planes intersect directly above us. Do they collide? Parametrize the linear paths and give the times when they are at the intersection point. By how many seconds do they miss each other?
Answer:
The answer is "40 second".
Step-by-step explanation:
Flight 101 headed north straight, ascended to a speed of 30,000 feet, and began a 360 mph cruising speed 10 kilometers from the point above our place. Flight 222, heading right west, was at the same time five miles east of the above-used spot already at 30 000 feet at 300 mph.

Y = 18
The values of {x} and {y} in the given right angled triangle is -
x = 9√3 and y = 18.
What is Pythagoras theorem?Pythagoras theorem states that the square of the hypotenuse is equivalent to the square of the base and perpendicular. We can write the formula for Pythagoras theorem as -
(hypotenuse)² = (base)² + (perpendicular)²
Given is a right angled triangle as shown in the image.
We can write the tangent function as -
tan(30) = 9/x
x = 9/tan(30)
x = 9√3
Similarly, we can write the sine function as -
sin(30) = 9/y
1/2 = 9/y
y = 18
Therefore, the values of {x} and {y} in the given right angled triangle is -
x = 9√3 and y = 18.

Answer:
4.8 km is the answer.
Step-by-step explanation:
