4 cups per quarter
4 x 7 = 28
28 kids can have a cup of hot chocolate.
Answer:
X=-3/2
Step-by-step explanation:
-2(x+2)=-1
Distribute
-2*x and -2*2
-2x-4=-1
Solve for x
-2x-4=-1
+4 +4
-2x=3
/-2 /-2
x=-3/2
Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm
Step-by-step explanation:
so 5/9(86-32) then you take
86-32=(54)
now it look like C=5/9=(54)
C=30
so c=30 is the answer :)
The initial height of the balloon is 10 feet which then increases by 70% to (10 ×1.7) = 17 feet, then to (17 × 1.7) =28.9 feet, and so fourth if the rate of increase is kept constant. Therefore, forming a geometric sequence such that to get any term in the sequence we use the formula ar∧(n-1), where a is the first term, r is the common ratio, and n is the term in the sequence. In this case a is 10 and r= 1.7 , to get the height in the fourth minute it means n =5 (for the first term there is 0 minutes, such that for 0 minutes n= 1)
Thus, 10 × 1.7 ∧ 4 = 83.521 feet.
Therefore, the answer is 83.521 feet
