Answer:
[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Two fractions
[tex]\frac{1}{2} / \frac{3}{5}[/tex]
Divide
______________
When dividing two fractions we follow KFC :
Keep
Change
Flip
Keep meaning to keep the fractions
Change meaning to change the division sign to the multiplication sign
Flip meaning to flip the second fraction.
KEEP -
[tex]\frac{1}{2} / \frac{3}{5}[/tex]
CHANGE -
[tex]\frac{1}{2} * \frac{3}{5}[/tex]
FLIP -
[tex]\frac{1}{2} * \frac{5}{3}[/tex]
Multiply across :
[tex]\frac{1*5}{2*3}[/tex]
[tex]\frac{5}{6}[/tex]
Answer:
the answer is 5/6
Step-by-step explanation:
1/2 ÷ 3/5

To prepare for a bake-off, Chad used 520 grams of flour each day for 2 weeks. How many kilograms did Chad use in those 2 weeks? 1 g = 0.001 k
Answer:
7.280 k
Step-by-step explanation:
Given that 1 g = 0.001 k
If he uses 520 grams of flour each day for 2 weeks, since there are 7 days in a week, the total weight of flour used in two weeks
= 520 g * 2 * 7
= 7280 g
In kilograms
Since
1 g = 0.001 k
7280 g = 7280/1 * 0.001 k
= 7.280 k
Find the value of x, show your work
Answer:
x=13
Step-by-step explanation:
114 = 8x +10
(subtract 10 from both sides )
114-10=8x
104=8x
(divide 8 by both sides )
x=13
Answer:
13
Step-by-step explanation:
8x + 10 = 114 these are vertical
8x = 104
x = 13

A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk mark returned to the
same position. The team then measured the distance the wheel had rolled and found it to be 25 cm. To the nearest tenth, what is the area of
the wheel?
49.7 cm?
198.9 cm?
99.5 cm
19.6 cm?
Answer:
49.7 [tex]cm^{2}[/tex]
Step-by-step explanation:
Although it is hidden a bit, we are actually given the circumference of the circle, which is 25 cm.
We know that C = 2πr, so we can substitute variables to find the radius (r).
25 = 2πr
r = 25/(2π)
r = 3.9788... cm
The area of a circle is A = π[tex]r^{2}[/tex], so:
A = π [tex]3.9788^{2}[/tex]
A = 49.7359... [tex]cm^{2}[/tex]
A ≈ 49.7 [tex]cm^{2}[/tex]

Solve the system of linear equations.
x−y=3
−2x+y=−5
Answer:
x=2 and y=-1
Step-by-step explanation:
x−y=3
x−y+y=3+y(Add y to both sides)
x=y+3
Substitutey+3forxin−2x+y=−5:
−2x+y=−5
−2(y+3)+y=−5
−y−6=−5(Simplify both sides of the equation)
−y−6+6=−5+6(Add 6 to both sides)
−y=1
−y
−1
=
1
−1
(Divide both sides by -1)
y=−1
Substitute−1foryinx=y+3:
x=y+3
x=−1+3
x=2(Simplify both sides of the equation)

what is the value of x
=》 6x + 6 = 42
Answer:
x = 6
Step-by-step explanation:
6x + 6 = 42
6x = 42 - 6
6x = 36
x = 36 / 6
x = 6
hope it helps :)
Answer:
6x + 6 = 42
6x = 42- 6
6x = 36
x= 36 /6
x= 6

PLEASE HELP ILL GIVE 40 POINTS! 1. Given: Angle 2 is 65 degrees. (a) What is the angle measurement of Angle 4. Explain the angle relationship used and show your work. (b) What is the angle measurement of Angle 7. Explain the angle relationship used and show your work. (c) What is the angle measurement of Angle 3. Explain the angle relationship used and show your work.
Answer:
Step-by-step explanation:
angle four and two must sum to 180 degrees because they are adjacent.
a4=180-65=115
opposite angles are equal
a7=a3=a2
a7=65
a3=a2 for the same reason as above
a3=65
Danielle has a third of the amount needed to pay for her choir trip expenses. Does the expression (77+106+34) divided 3 show how you could calculate the amount of money Danielle has?
Answer: Yes. The expression can be used to calculate how much Danielle has.
Step-by-step explanation:
The choir trip expenses are:
Train tickets = $77
Hotels = $106
Meals = $34
Total expense = $77 + $106 + $34 = $217
Since we are told that Danielle has a third of the amount needed for the trip. This means that we have to calculate 1/3 of $217 This will be:
= 1/3 × $217
= $72.33
Also, the expression (77+106+34) divided 3 shows the amount that Danielle has. Thus will be:
= (77+106+34) / 3
= 217/3
= 72.33
How many terms are in this expression?

How do u know if an ordered pair is a function?
EXAMPLE/
(0,3)
(1,6)
(2,12)
(3,24)
(4,48)
(5,96)
are these pairs a function WHY/WHY NOT
Step-by-step explanation:
How do you figure out if a relation is a function? You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function!
3. What is the total surface area of the square
pyramid in square inches?
1
11.5 in
7 in
Answer:
area of a triangular face = ½(base)(side length) = ½(7)(11.5) = 40.25 in
lateral area = all four triangles = 161 in²
base area = 7² = 49 in²
total surface area = lateral area + base area = 161+49 = 210 in²
