What is 7/8 divided by 2/8
Answer:
7/8 ÷ 2/8 = 3 1/2
Step-by-step explanation:
When we divide two fractions, such as 7/8 ÷ 2/8, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
The quotient obtained from the division of given fractions is 7/2.
Given that, 7/8 divided by 2/8.
Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.
Here, 7/8 ÷ 2/8
= 7/8 × 8/2
= 7/2
Therefore, the quotient obtained from the division of given fractions is 7/2.

there is a bag filled with 6 blue and 5 red marbles.
a marble is taken at random from the bag the colour is noted and then it is replaced. another marble is taken at random. what is the probability of getting 2 reds
Answer:
Step-by-step explanation:
The probability of obtaining a red marble in one sample is 5/11. Since you are sampling twice the probability of picking a red marble both times is 5/11 x 5/11 = 25/121. That is slightly less than one time in five.
X over 25 equals 35 over 14 solve for the missing variable

how do you add with a negative number?
The 5th term of an arithmetic sequence is 30, while the 13th term is 70
Answer:
a = 10
d = 5
Step-by-step explanation:
[tex]a_{n}=a + (n-1)d\\\\a_{5}=30\\\\a + (5-1)*d=30\\\\[/tex]
a + 4d = 30 ------------------(I)
[tex]a_{13}=70\\\\a + (13-1)d=70[/tex]
a + 12d =70 -------------(II)
Multiply equation (II) by (-1) and then add.So, 'a' will be eliminated and you can find the value of d
(I) a + 4d = 30
(II)*(-1) -a - 12d = -70 {Now add}
- 8d = - 40
Divide both sides by (-8)
d = -40/-8
d = 5
Plugin d = 5 in equation (I)
a + 4*5 = 30
a + 20 = 30
a = 30 - 20
a = 10

Miguel's mother builds and sells houses. She wants to buy a piece of land on which to build several houses. There are two lots for sale. One is a rectangular plot that is 3/8 of a mile by 2/3 of a mile. The other square plot that is 2/5 of a mile.
Part A
Which lot should Miguel's mother buy if she wants the biggest lot?
Part B
If the land in the area sells for 750,000 a square mile, how much should she expect to pay?
Answer:
Square lot and 187500
Step-by-step explanation:
To find question number A, we can calculate the area of each lot. The square plot is:
2/5×2/5=4/25
The first one is
2/3×3/8=1/4
Then we can make both have the same denominator:
1/4=25/100, 4/25=16/100
That means that the square lot is bigger.
We know that the area is 1/4 square mile. So it's 1/4 of 750,000
That's
1/4×750000=187500
Hope that helps! :)

Tory creates a cell phone app. He wants to distribute it through a company that will pay him $100 plus $0.25 every time the app, x is downloaded. In the first month he made $380.
The equation that can be used to determine how many times the app, x, was downloaded is
The app was downloaded 1120 times for Tory to earn $380.
A linear equation is in the form:
y = mx + b;
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total money paid to download the app x times.
The company pay him $100 plus $0.25 every time the app is downloaded. hence b = 100, m = 0.25
y = 0.25x + 100
For making 380:
380 = 0.25x + 100
280 = 0.25x
x = 1120
Therefore the app was downloaded 1120 times for Tory to earn $380.

A) no solution
B) one solution
C) two solutions
D) infinitely many solutions
Answer:
A) no solution
Step-by-step explanation:
These lines are parallel. Which means that they will never intersect, and since the solution to a system of equations is the point or points of intersection, this means there would be no solution to this system.

Enter your answer in the box.

Angle A and B are shown to be the same which means the 2 sides are the same. Using the 2 sides solve for x.
2x -24 = x-2
Add 24 to both sides
2x = x + 22
Subtract x from both sides:
X = 22
Bc = x , so BC = 22

for a field trip the school bought 47 sandwiches for $4.60 each and 39 bags of chips for $1.25 each.How much did the school spend in all?
Answer: To get to your final sum you will have to calculate the sum of both items: the sandwiches and the chips. Then you will get the total sum of all what they spend.
Step 1:
Sum of one sandwich= 4.60 dollar
sum of 47 sandwiches= 47×4.60 =216.2dollars
Step 2:
Sum of one chip=1.25 dollar
sum of 39 bags of chips=39×1.25= 48.75dollars
step 3: sum up the sum of sandwiches and that of the chips
216.2 + 48.75 =264.95dollars

Solve. Trigonometry using cosine, tangent and sine
Answer:
CD = 30.43; LK = 14.08
Step-by-step explanation:
Problem 12.
Let's first find BD. Triangle ADB is a right triangle with hypotenuse AB. By definition of sine ( or by theorem, they're equivalent) [tex]{BD \over 20} = sin 54.[/tex], hence BD= 16.18. Jump on the other side now. Triangle BDC is a right triangle with sides BD and CD. By definition of tangent [tex] {{16.18} \over CD} = tan 28 [/tex], thus CD= 30.43.
Problem 13
Assuming the 72° is angle JLK
As usual, triangle MJL is a right triangle with sides MJ and LJ. By definition of tangent [tex] {{JL} \over 14} = tan 51 [/tex]. Follows that JL = 14.81. Now, similarly, trinagle JLK is a right triangle, with hypotenuse JL. From the definition of sine, as before,[tex]{KL \over 14.81} = sin 72.[/tex]. Solving for the only unknown value, you find LK = 14.08.

3. Physics students were modeling the height of a ball once it was dropped from the roof of a 25 story
building. The students found that the height in feet, h, of the ball above the ground as a function of the
number of seconds, i, since it was dropped was given by h(t)= 300 - 1612.
From what height was the ball dropped?
To the nearest tenth of a second, determine the time at
which the ball hits the ground. Provide evidence from a
table to support your answer or solve this algebraically
if you recall how to.
It will take 4.3 seconds for the ball to hit the ground
Given the eqation of the height at which the object dropped expressed as
h(t) = 300 - 16t²
The object will hit the ground at when h(t) = 0
Substitute h(t) = 0 into the expression to have;
0 = 300 - 16t²
16t² = 300
t² = 300/16
t² = 18.75
t = 4.33sec
This shows that it will take 4.3 seconds for the ball to hit the ground
