Hello! I'm looking for help on the question: 6 2/3 x 3/10 in simplest form. Thank you! ^^
Answer:
6/5 or 1 and 1/5
Step-by-step explanation:
To do this you need to multiply 6/1, 2/3, and 3/10 all together by cancelling out the numerator in 3/10 and the denominator for 2/3. Then you would be left with 6*2*1/10
This simplifies to 6*1/5 because of the 2*1/10 is 1/5, because 1/5 doubled is 1/10.
then multiply the numerator and 6 together to get 6/5.
Hope this helps!
31. REWRITING A FORMULA A common statistic used in
professional football is the quarterback rating. This
rating is made up of four major factors. One factor is
the completion rating given by the formula
R= 5
5C - 0.3)
where C is the number of completed passes and A is
the number of attempted passes. Solve the formula
for C.
Solving for a variable in an equation means that we want to make the variable the subject of the formula. The equation of C is: [tex]C = 0.04R + 0.06[/tex]
Given that:
[tex]R = 5(5C - 0.3)[/tex]
To solve for C, means that we make C the subject.
Divide both sides by 5
[tex]\frac R5 = 5C - 0.3[/tex]
[tex]0.2R = 5C - 0.3[/tex]
Add 0.3 to both sides
[tex]5C = 0.2R + 0.3[/tex]
Divide both sides by 5
[tex]C = 0.04R + 0.06[/tex]
Hence, the equation of C is:
[tex]C = 0.04R + 0.06[/tex]

Answer:
h = 5
Step-by-step explanation:
area = 1/2 base × hight
base = 3 +h
hight =9 + 6 = 15
60 = 1/2 × 15 × (3+h)
120/15 = 3 + h
8 = 3 + h
h = 5
Answer:
h = 5
Step-by-step explanation:
The value of h can be obtained by using area of triangle formula as well as distance formula.
[tex]A(\triangle ABC) =\frac{1}{2} \times AB\times AC \\ \\ 60 = \frac{1}{2} \times \sqrt{ {( - 3 + 3)}^{2} + (9 + 6) ^{2} } \\ \times \sqrt{ {(h + 3)}^{2} + {(9 - 9)}^{2} } \\ \\ 60 \times 2= \sqrt{ {( - 0)}^{2} + (15) ^{2} } \\ \times \sqrt{ {(h + 3)}^{2} + {(0)}^{2} } \\ \\ 120= \sqrt{ 0 + (15) ^{2} } \times \sqrt{ {(h + 3)}^{2} + 0 } \\ \\ 120= \sqrt{ (15) ^{2} } \times \sqrt{ {(h + 3)}^{2} } \\ \\ 120 = 15(h + 3) \\ \\ \frac{120}{15} = h + 3 \\ \\ 8 = h + 3 \\ \\ h = 8 - 3 \\ \\ h = 5[/tex]

Answer:
(B) 4
Step-by-step explanation:
Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...
3 + 8 = 11
This tells you A = 8, so the top number is 1983, and the middle number is B78.
Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...
1 + 9 + B = <something ending in 4>
We know the something cannot be 04 or 24, so must be 14. Then ...
10 + B = 14 ⇒ B = 4
__
So, the whole sum is ...
1983 +478 = 2461
and the letter values are ...
A = 8B = 4D = 2Answer:
B is 4.
Step-by-step explanation:
If we start by the ones place and add we know that to get a one the total must be 11. 11-3 = 8. Therefore A = 8.
Now we move to the tens place, since we know A is 8 we can substitute it there. Don't forget to add the one from the 11 we got. 1+8+7 = 16
Now we move to the hundreds place and we carry our one from 16 so now it's 1 + 9 + ? = 4, if we know that our total needs to be 14 in order to have the 4 there- 1 + 9 is 10 we can do 10 + 4 and that gets us 14. So B is 4.
The hypotenuse of a right triangle is 65 cm, if one of its sides is 25 cm, find the length of the other side and it's perimeter
I will name you brainless if you give correct answer
Answer:
Other side = 60
Perimeter = 150
Step-by-step explanation:
Using Hypothenuse formula
25²+B²=65²
625+B²=4225
B²=4225-425
B²=3600 (Bring Square to the other side to become Square root)
B=√(3600)
B=60
Perimeter:(Sum of all side)
60+65+25

Step-by-step explanation:
If the x-coordinate of R is 6 units away from D's x-coordinate, then so will J's x-coordinate. If the y-coordinate of R is 8 units away from D's y-coordinate, then so will J's y-coordinate.

Answer:
[tex]x=-1,\displaystyle \frac{5}{3}[/tex]
Step-by-step explanation:
Hi there!
[tex]6x^2=4x+10[/tex]
Move 6x^2 to the other side of the equation:
[tex]0=-6x^2+4x+10[/tex]
Divide both sides by -2:
[tex]0=3x^2-2x-5[/tex]
Factor by grouping:
[tex]0=3x^2+3x-5x-5\\0=3x(x+1)-5(x+1)\\0=(3x-5)(x+1)[/tex]
Apply the zero product property:
[tex]3x-5 = 0\\3x=5\\\\x=\displaystyle \frac{5}{3}[/tex]
[tex]x+1=0\\x=-1[/tex]
Therefore, x = -1, 5/3.
I hope this helps!

Lauren has finished 25% of the 120 push ups she needs to do for softball
practice. How many of the total push ups has she now finished?
Answer:
30 pushups
Step-by-step explanation:
25/100 = x/120
so, 120x25 = 100x
3000 = 100x
3000/100= x
x = 30
so, Lauren has completed 30 push-ups.
