Whatever% of anything is just (whatever/100) * anything.

let's first convert the mixed fraction to "improper" and then divide it by 100 to make decimal.

\bf \stackrel{mixed}{8\frac{1}{4}}\implies \cfrac{8\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{33}{4}}
\\\\\\
\stackrel{\%}{\cfrac{33}{4}}\implies \cfrac{\quad \frac{33}{4}\quad }{100}\implies \cfrac{\quad \frac{33}{4}\quad }{\frac{100}{1}}\implies \cfrac{33}{4}\cdot \cfrac{1}{100}\implies \cfrac{33}{400}\implies \stackrel{decimal}{0.0825}

astraxan [27]

Answer:

a) 4 1/10 slices eaten

b) cannot be solved because we don't know how many slices in each pizza

Step-by-step explanation:

5*1/10=5/10

12*3/10=36/10

36/10+5/10=41/10

41/10=4 1/10 slices

Solving a system of linear equations using the substitution method. <br> 5x+4y=-26<br> 5-x=-6y
yan [13]
Solve for x in 2nd equation
times -1 both sides
x-5=6y
add 5
x=6y+5

sub

5(6y+5)+4y=-26
30y+25+4y=-26
34y+25=-26
minus 25 both sides
34y=-51
divide both sides by 34
y=-3/2
sub back

x=6y+5
x=6(-3/2)+5
x=-18/2+5
x=-9+5
x=-4


(-4,-3/2) is solution

What is the gcf of 21 30 anwhat is the gcf of 21 , 30 ,and 44?
Ymorist [56]
Find the prime factorization of each value.

21 is 7*3

30 is 3*10 which can be further broken down into 3*2*5

44 is 4*11 which can be further broken down into 2*2*11

What do they share in common?
21 and 30 each have a 3 in common.
Therefore the GCF(21, 30) = 3.

21 and 44 share a 2 in common.
But if we're looking at all three of them together, they share nothing in common.

The diameter of a circle is 26 millimeters. What is the circle's circumference?
Shkiper50 [21]

Step-by-step explanation: the answer for this question should be 81.64 because to find the circumference you need to know the circumference formulas which is  C=TT times d or          C= 2 times TT times r.

C= 3.14 times 26          C= 2 times 3.14 times 13

                                       C= 81.64

C= 81.64

so the answer is 81.64 for the circle's circumference so hopefully that is the correct answer and have a great day
