Because JKLM is a parallelogram, MT = TK.
MT: 8y + 18
TK : 12y - 10
MT = TK
8y + 18 = 12y - 10
8y - 12y = -10 -18
-4y = -28
y = -28/-4
y = 7
MT: 8y + 18 → 8(7) + 18 = 56 + 18 = 74
<span>TK : 12y - 10 </span>→ 12(7) -10 = 84 - 10 = 74
The value of y is 7.
Answer:
Step-by-step explanation:
First I want to set up some variables.
S = sum
n = final term
ax = xth term, so a1 is the first term and an is the last one
d = common difference.
There are two formulas to find the sum, if you don't get how they were gotten I'd be happy to explain.
S = (n/2)(a1+an) = (n/2)(2a1+(n-1)d)
So, to find n we use the first one.
S = (n/2)(a1+an)
123 = (n/2)(8+33)
123 = (n/2)41
3 = n/2
6 = n
Now we can find d with the other one
S = (n/2)(2a1+(n-1)d)
123 = (6/2)(2*8+(6-1)d)
123 = 3(16+5d)
41 = 16+5d
25 = 5d
5 = d
so there are six terms and the common difference is 5.
Let no of blueberries be x
2 x bluberries = total raspberries
So raspberries = 2x
Cherries= 4 x raspberries so
Cherries = 8 x
Grapes = 3x cherries so
Grapes = 24x
Total fruit is equal to
X+2x+24x+8x=280
35x=280
Therefore X= 280/35=8
No of cherries in the salad
=8x
=8(8)
=64 cherries in total
Hope this helped and sorry I used shortcuts
Hope u understand
Writing in the form of power of 3 can be wrote a lot of ways. Any number to the power of 3 van also be read as the number to the power of 3, or the number cubed. Lets do some examples:-
3³ = 3 × 3 × 3 = 27
3³ = 27
3³ = three cubed = three to the power of 3
5³ = 5 × 5 × 5 = 125
5³ = 125
5³ = five cubed = five to the power of 3
(These are just 2 examples. There are MANY more.)
Hope I helped ya!!
Answer:
<h2>
AB is around 33.18</h2><h2>
BC is around 15.58 </h2>
Step-by-step explanation:
adjacent/hypotenuse is sine:
cos(28 degrees)=29.3/x
cos(28 degrees)*x=29.3
x=29.3/cos(28 degrees)
x=around 33.18
AB is around 33.18
opposite/adjacent is tangent
tan(28 degrees)=x/29.3
tan(28 degrees)*29.3=x
x=tan(28 degrees)*29.3
x=around 15.58
BC is around 15.58
