How do you write 3,390 in scientific notation?
x 10
Answer:
3.39 × [tex]10^{3}[/tex]
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive. Since the decimal is going right, the exponent will be positive

Esteban finds 12 baseball cards on Monday and 24 more baseball cards on Tuesday. He gives some baseball cards to his sister, and now he has 13 baseball cards left. How many cards did he give to his sister?
Answer:
23 cards.
Step-by-step explanation:
After Monday, Esteban has 12 cards.
After Tuesday, Esteban has 12 + 24 = 36 cards.
He gave to his sister x cards.
36 - x = 13
36 = 13 + x
23 = x

Kari plans to sample 20 people of a population that contains 100 students. She wants to determine how many people wake up before 6 a.m. Which sample is the most random?
the first 20 students who arrive at school in the morning
all 20 boys on the swim team
5 students out of each of the 4 homeroom classes
the last 20 people in line for breakfast in the cafeteria
Answer:
5 students out of each of the 4 homeroom classes
Step-by-step explanation:
The most random sample is 5 students out of each of the 4 homeroom classes.
Thus, option (C) is correct.
Selecting 5 students from each of the 4 homeroom classes ensures that the sample represents a diverse range of students from different classes.
This approach helps to minimize bias and increase the randomness of the sample.
The other options, such as selecting the first 20 students who arrive at school or the last 20 people in line for breakfast, may introduce some bias based on the specific circumstances or characteristics of those groups. Selecting all 20 boys on the swim team would also not provide a representative sample of the overall student population.
Thus, option (C) is correct.

Get gud at math you newb
Answer:
2x^7y^6
Step-by-step explanation:
you do x^5 = X x X x X x X x X and x^2 is X x X so X^5 x X^2 is X x X x X x X x X x X x X which can be simplified to X^7
and the same for y
y^4 = Y x Y x Y x Y and y^2 is Y x Y, so Y^4 x Y^2 = Y x Y x Y x Y x Y x Y which simplifies to Y^6

There are 14 girls and 12 boys in a class. What is the ratio of girls to students?
Answer:
7:13
Step-by-step explanation:
There are 14 girls and 12 boys, so there are 26 students in total. Since we are looking for the ratio of girls to students, the ratio will be 14:26. To simplify it, we will divide 14 and 26 by their greatest common factor: 2. We will get the ratio of 7:13.

if mr.s rivas has 256 donust and she needs to give the same amount of dounts to her 5 freinds
Answer:
256/5=51.2
Step-by-step explanation:
Answer:
51 with a remainder of one, or 51.2
Step-by-step explanation:
She has 256 donuts and 5 friends. I assume this is for long division practice, so I will do long division.
5 | 256
Look at the first term. Does 5 go into 2? No. Bring down the next term.
5|256
25
Does 5 go into 25? Yes! How many times? 5. The first digit of our answer will be 5.
5|256 = 5
25
Now to get rid of the 25, we multiply the number we took for our answer by the divisor. 5x5 = 25. Subtract this from 25 and bring down the next (and last term).
5|256 = 5
25
-25
06
Does 5 go into 6? Yes. One time. Repeat what we did just now with this term now.
5|256 = 51
06
-5
1
Does 5 go into 1? No, it is smaller. Therefore we have a remainder of one donut.
If we are trying to divide ALL of the donuts equally, we will have to cut up the donut into 5 equal pieces. They would each be 1/5 of the donut, or 0.2.
So adding this, each friend would get 51 donuts, with an extra donut for Mrs Rivas, or each friend would get 51.2/51 and 1/5 donuts.

The Martin family has three children. One is in elementary school, one is in middle school, and one is in high school. They are moving and would like to
live at a location that is the same distance from each of the three schools. They have mapped the schools in a coordinate plane. Determine the
coordinates of the best location that will be equidistant from all three schools.
Answer:
Answer is 1/2,-1 1/2
Step-by-step explanation:
The coordinates of the best location that will be equidistant from all three schools is; (-0.085, -2.232).
What is circumcenter of a triangle?The circumcenter of a triangle is defined as the point where the perpendicular bisectors of the sides of that particular triangle intersect. In other words, the point of concurrency of the bisector of the sides of a triangle is called the circumcenter.
The coordinates of the 3 points that form a triangle attached in the image are;
A(-4, -2), B(0, 3), C(5, -1)
Since the distances to the circumcenter O from the vertices are all equal.
Then; AO = BO = CO.
From the first equality, we have AO² = BO²
(x + 4)² + (y + 2)² = (x - 0)² + (y - 3)²
⇒ 8x + 16 + 4y + 16 = – 6y + 9
⇒ 8x + 10y = -23 ---(1)
Similarly, from the second equality, we have BO² = CO²
(x - 0)² + (y - 3)² = (x - 5)² + (y + 1)²
⇒ – 6y + 9 = -10x + 25 + 2y + 1
⇒ 10x - 8y = 17 ----(2)
Solving eq 1 and 2 simultaneously gives;
x = -0.085
y = -2.232
Therefore, the coordinates of the best location that will be equidistant from all three schools is; (-0.085, -2.232).

Solve the equation for y. Type out your steps to solve this problem as you are showing your work:
7(y + 3) = 5y + 8
Answer:
-13/2
Step-by-step explanation:

7y+21=5y+8
7y-5y+21=8
2y+21=8
2y=8-21
2y=-13
y=-13/2
Answer:
y = -6.5
Step-by-step explanation:
simplify: 7y+21=5y+8
put like-terms together and simplify: 2y=-13
(like-terms: 7y-5y=8-21)
divide both sides by 2: y=-6.5

Two streets form an intersection. C and D are supplementary
angles. If the measure of C is 140° and the measure of D is
two times the value of x, what is the value of x?
Answer:
20degrees
Step-by-step explanation:
The sum of angle C and D is 180 degrees since they are supplementary
Given
m<C = 140 degrees
m<D = 2x
Taking the sum and equating to 180
140 + 2x = 180
2x = 180-140
2x = 40
x = 40/2
x = 20 degrees
Hence the value of x is 20degrees
using compound interest, how long does it take to double a 1000 dollar investment that pays 6.5% annual interest, compounded monthly?
Answer:
11 years approx
Step-by-step explanation:
Given data
P=$1000
A=2000
R=6.5%
T= ?
Calculate time, solve for t
t = ln(A/P) / r
substitute
t=ln(2000/1000)/0.065
t=ln(2)/0.065
t=0.693/0.065
t=10.66
Hence the time is 11 years approx
