The area of a triangle is 60 cm2. Its base measures 5 cm. What is the triangle's
height on this base?
possible answers:
7.75 cm approximately
12 cm
24 cm
150 cm
Answer:
24
Step-by-step explanation:
Answer:
h = 24 cm
Step-by-step explanation:
Area = 1/2 b * h
b = 5 cm
Area = 60 cm^2
60 = 1/2 * 5 * h Multiply both sides by 2
60*2 = 2*1/2 * 5 * h
120 = 5 h Divide by 5
24 = h

what is the mode of 81 87 93 89 61 81
if you give the steps il give you brainlyest
Hello there! :)
To find the mode, we must simply find the number that is seen most often in the dataset.
Here, the number 81 is seen twice.
87 is seen once
93 is seen once
89 is seen once
61 is seen once
So 81 is the mode.
Hope that helps you!

A news report says that 9% of middle school students are on the track team.
There are 600 students in your middle school.
How many students in your school would you expect to be on the track team?
Answer:
54
Step-by-step explanation:
1% of 600 is 6 (600/100), so 9% of 600 is 54
Answer:
54 students
Step-by-step explanation:
To calculate 9% of 600 first convert 9% to a decimal. This is done by dividing it by 100.
9% ÷ 100% = 0.09
Multiply 600 by 0.09:
600 × 0.09 = 54
So 54 students at the middle school are on the track team.

Below are descriptions of two different objects that begin at rest and then now forces acting on them as described below.
Object 1: A skateboard with unbalanced forces
Object 2: A bicycle with balanced forces
Which statement is true about the objects?
Both objects are moving.
Both objects are not moving.
Object 1 is moving, and Object 2 is not moving.
Object 1 is not moving, and Object 2 is moving.
Answer: C: object 1 is moving, and object 2 is not moving
Step-by-step explanation since object one is on unbalanced forces, it can cause it to start moving (ex: a hill, if a skateboard is sitting on the top of a hill on unbalanced forces it will probably roll down.) but since object 2 is on balanced forces it wont start to move and/or roll forwards or anything like that.

Which of the following statements best defines mutually exclusive events?
A. Two events are mutually exclusive if it is impossible for the two events to occur simultaneously.
B. Two events are mutually exclusive if the occurrence of one event has no effect on the
probability of the other.
C. Two events are mutually exclusive if the intersection between the sample spaces of the two
events is not empty.
D. Two events are mutually exclusive if the union of the sample spaces of the two events is not
empty.
The statements which best defines the mutually exclusive events is two events are mutually exclusive if it is impossible for the two events to occur simultaneously (A).
When two events are said to be mutually exclusive?The two events area said to be mutually exclusive when the cannot be take place simultaneously. For the two events, A and B, to be mutually exclusive,

which of the following is closest to 4? ill give brainliest if able to
18, 19, 13, 15.
Answer:
D. [tex]\sqrt{15}[/tex]
Step-by-step explanation:
We can start by squaring each of the options and also squaring 4. This will make it easier for us to compare all the values:
[tex]4^{2} =16\\[/tex]
[tex]\sqrt{18}^{2} =18[/tex]
[tex]\sqrt{19}^{2}=19[/tex]
[tex]\sqrt{13}^{2} =13[/tex]
[tex]\sqrt{15}^{2} =15[/tex]
Which of these values (18, 19, 13, or 15) is closest to 16? 16 and 18 have a difference of two. 16 and 19 have a difference of three. 16 and 13 have a difference of three. Finally, 16 and 15 have a difference of one. So, we know that [tex]\sqrt{15}[/tex] is the closest in value to 4.
Hopefully that was helpful! If you have any more questions, let me know. :)
