Answer:
77m
Step-by-step explanation:
Area of rectangle = L x W
7536m² = 98 x W
(Divide both sides by 98 to get W)
W = 7536m ÷ 98m
W = 77m

If you have piano lessons every 7 days and tuba lessons s every 3 days, how many days before you have them together
21 days before I had both the lessons together.
For the occurrence of two events at the same time we will find the least common multiple.
If I have piano lessons on every 7th day and tuba lessons on every 3rd day,
Least common multiple of 3 and 7 will be,
Multiples of 3 = 1 × 3
Multiples of 7 = 1 × 7
Least common multiple (LCM) of 3 and 7 = 3 × 7
= 21
Therefore, 21 days before I had both the lessons together.

What is the fewest number of intersection points that two planes can have?
Answer: 4 points
Step-by-step explanation:
The minimum number of points needed to define two distinct planes is 4 points. Two distinct planes can be defined by 4 points under the conditions that the two distinct planes intersect at a line, and two points exist on that line that are shared between the planes.
Answer:
One line of intersection (three points of intersection)
Step-by-step explanation:
When two planes intersect, they don't form points of intersection, but they form a line of intersection.
From equation of a line,
[tex]{ \tt{ax + by + cz = 0}}[/tex]
x, y, z are points of intersection

A customer wants to buy 0.3 pounds of mulch that cost $7.30 per pound. if the customer has a coupon for $0.50 off the total cost, how much will they pay for the mulch?
Answer: The customer will pay 1.69$ for the mulch.
Step-by-step explanation:
7.30 = 1 Pound
0.3 = 3/10
3/10 x 7.30 or 3/10 of 7.30 = 2.19
2.19
2.19 = without coupon
1.69 = with coupon.
The total with 50 cents off is 1.69$.

3 Answers: Choice A, Choice B, Choice E
=========================================================
Explanation:
We have four copies of x in the original expression. So that accounts for the 4x. In other words, 4x = x+x+x+x. Multiplication is used for repeated addition.
Also, the other terms add to 15+5+15+5 = 20+20 = 40
Therefore, we end up with 4x+40 from choice A.
-----------------------------
Once we get to 4x+40, we can factor out 2 from it like so
4x+40
2*2x + 2*20
2(2x+20) which is choice B
I used the distributive property to factor. That rule is a(b+c) = ab + ac
-------------------------------
Choice C is not one of the answers. We can determine this fairly quickly by noting that the expression in choice C talks about a quadratic, but the original expression given to us is linear.
Choice D is a similar story to choice C.
--------------------------------
Choice E is another answer
This is because we have two copies of (x+15), so that gives 2(x+15)
We also have two copies of (x+5) to get 2(x+5)

-8 You burn 6 grams of carbon in plenty of air: C(s) + O₂(g) →→→ CO₂ (g) a What volume of gas will form (in dm³ at rtp)? b What volume of oxygen will be used up?
a) Gas has a volume of 12 liters.
b) 12 liters of oxygen gas will be consumed during the reaction.
Step-by-step explanation:
Moles of Substances:
We measure the quantity of atoms and molecules in moles, which is equal to 6.022 ×10²³, Avogadro's number, because they are too small to be counted or weighed individually. A substance's atomic mass is multiplied by Avogadro's number to get its mass in grams.
Here, Half a mole of carbon is equal to six grams of carbon. since 12 grams make up one mole of carbon. Since carbon dioxide has the chemical formula CO2, when a mole of carbon is fully combusted, it will result in the production of a mole of carbon dioxide gas.
a) Half a mole of gas has a volume of 12 liters because one mole of gas at RTP consumes 24 liters.
b) Due to the fact that each oxygen molecule contains two oxygen atoms and each carbon dioxide molecule contains two oxygen atoms, 12 liters of oxygen gas will be consumed during the reaction.

5 ∈ Q.
c. P ∩ Q = Ф True - This says that there are no common elements in P and Q which is true. Ф is the 'empty set'.
d. True: n(P) = 4 means there are 4 elements in P.
e. True: there are 4 elements in P and in S.
S can be written as {3, 4, 5, 6} - that is the integers which are greater than 2 and less than or equal to 6. The Z means the set of integers.
a test shows that 10 out of 100 gadgets are defective. in a random sample of two gadgets are chosen the probability that both are defective is
The probability of selecting both defective gadgets out of 100 gadgets is 1/110, which is calculated using the basic concepts of probability theory.
What is a random experiment?
An experiment that is repeated several times and produces more than one possible outcome is called as the random experiment. It contains a well-defined set of values which constitutes a sample space. Eg: Rolling a die, tossing a coin etc.
Calculation of the probability of selecting both gadgets as defective
The total amount of gadgets = 100
Number of defective gadgets = 10
The probability of selecting a defective gadget is 10 / 100 or 1 / 10
Now, the total number of gadgets and defective gadgets are decreased by 1
So, the probability of selecting another gadget as defective is 9 / 99 or 1 / 11
P(E) = P(when two selected gadgets are defective) = 1 / 10 x 1 / 11
P(E) = 1 / 110
Hence, the probability of selecting both defective gadgets is 1/110.

Write the slope-intercept equation of a line that passes through the points (-2,5) and (6,-4)
The slope-intercept equation of a line that passes through the points (-2,5) and (6,-4) is [tex]y=-\frac{9}{8}x+\frac{11}{4}[/tex]
We know that the slope-intercept form of the line is y = mx + c, where m is the slope of the line and c is the y-intercept of the line.
For given question we have been given two points (-2,5) and (6,-4)
We need to find the slope-intercept equation of a line that passes through the points (-2,5) and (6,-4).
Using two-point form the equation of the line is,
[tex]\frac{y-y_1}{y_2-y_1}=\frac{x-x_1}{x_2-x_1}[/tex]
Let (x1, y1) = (-2,5) and (x2, y2) = (6,-4)
So, the equation of the line is,
[tex]\frac{y-5}{-4-5} =\frac{x-(-2)}{6-(-2)}\\\\ \frac{y-5}{-9} =\frac{x+2}{6+2}\\\\\frac{y-5}{-9} =\frac{x+2}{8}\\\\ 8(y-5)=-9(x+2)\\\\8y-40=-9x-18\\\\8y=-9x-18+40\\\\8y=-9x+22\\\\y=-\frac{9}{8}x+\frac{11}{4}[/tex]
above equation is in the slope-intercept form.

The sum of 2 integers is 7 and the sum of their squares is 37 what is the integers
Answer:
[tex]1[/tex] and [tex]6[/tex].
Step-by-step explanation:
Let [tex]x[/tex] denote one of the integers. Since the two integers add up to [tex]7[/tex], the other integer would be [tex](7 - x)[/tex].
The sum of the squares of these integers is [tex]37[/tex]. In other words:
[tex]x^{2} + (7 - x)^{2} = 37[/tex].
Expand [tex](7 - x)^{2}[/tex] using binomial expansion. Simplify and rewrite this equation and solve for [tex]x[/tex].
[tex]2\, x^{2} - 14\, x + 12 = 0[/tex].
[tex]x^{2} - 7\, x + 6 = 0[/tex].
Using the quadratic formula or factorization, [tex]x = 1[/tex] or [tex]x = 6[/tex]. Thus, the two integers are [tex]1[/tex] and [tex]6[/tex].
