A child planted five beans. How many bean plants will grow? x equals the number of bean plants that will grow. There will not be more than five plants, but there could be less if not all of the beans grow.
X is less than or equal to 5
X ≤ 5
116 1/4 = 465/4 and 2 2/9 = 20/9
(465/4)÷(20/9) will be the answer and it is equal to 52 flags
Answer:
14.54
Step-by-step explanation:
In a <em>weighted average</em> a “weight” is associated to each value.
The weighted mean is computed the following way:
Suppose you want to calculate the weighted mean of the values
a1, a1, …, an
with weights
w1, w2,..., wn
Then
<em>Weighted mean</em> =(w1*a1+w2*a2+... +wn*an)/(w1+w2+...+wn)
In this case we have
a1= 12, w1 = 8
a2 = 13, w2 = 6
a3 = 17, w3 = 12
<u>Weighted mean </u>
(12*8+13*6+17*12)/(8+6+12) = 14.54 rounded to 2 decimal places.
Answer:
The total number of boxes of canned food brought in by the three grades is 17.63 boxes
Step-by-step explanation:
To find the total number of canned foods brought in by the three grades, we will have to add the number of canned foods brought by each of the grades to each other. Careful attention has to be paid to the decimal points.
Canned foods brought by 6th graders: 5.75 boxes
Canned foods brought by 7th graders: 6.5 boxes
Canned foods brought by 6th graders: 7/1.3 boxes
We may have a slight challenge adding in 7/1.3 boxes to the other figures. What we can do now is to evaluate it to a decimal value by dividing it up.
7/ 1.3 will be the same thing as 7 divided by 1.3 = 5.38 boxes.
hence, we have 5.75 +6.5+ 5.38= 17.63 boxes
The total number of boxes of canned food brought in by the three grades is 17.63 boxes
Answer:
x = 63
Step-by-step explanation:
a triangle is always 180 degrees, so you equation would be:
180 - 42 - 43 - 32 = x
180 - 42 - 43 - 32 = 63
so x = 63
