7yd. because 1×1=1 , 1×3=3 , and 3×1=3 and if you add them together it's 7.
Answer: 3/11 pounds of seeds = 1 row of sunflowers
3/4 pounds of seeds = x
x stands for the unknown number of rows of sunflowers
To find x : Cross multiply
3x/11 = 3/4
3(11) = 4(3x)
12x = 33
Divide both sides by 12 ( so that we would be left with only x)
12x/12 = 33/12 ( where we have 12x/12 ; 12 is common in both the numerator and denominator so they will cancel out each other).
We are left with : x = 33/12
x= 2.75
x = 3 (approximated to a whole number)
Therefore: number of rows of sunflowers is 3 ☺
Answer:
55 degrees
Step-by-step explanation:
All angles in a triangle must equal 180 degrees when added together
They provide you with 2 angles 35 degrees and 90 degrees
So, you add 35 + 90 = 125
So you know that the 2 angles they give you equal 125 degrees
Now, you subtract 180 - 125 = 55
So the missing angle is 55 degrees
Answer:
the n(P) of P = {3, 5, 7, 11, 13, 17, 19} is "128".
Step-by-step explanation:
n(P) is the <u>Cardinality</u> of the set P. Its formula is 2^k.
where k = number of elements in the set.
Hope this helps :)
Answer:
let one part =x
part of vinegar= x
part of oil =2x
part of oil +part of vinegar = 450ml
2x+x=450
3x=450
x=450/3
x=150
part of vinegar=150ml
part of oil= 300ml
