Answer:
C. 19.
Step-by-step explanation:
Let's find the answer.
Step 1: divide the first number of 76, which is 7, by 4 and find the integer part.
7/4=1.75, so the integer part is 1.
Step 2: subtract from 7 the (integer part times 4)
7-(1*4)=3
Step 3: put toether the result (3) and the second number of 76, which is 6, so the result is 36.
Step 4: find how many times we need to add 4s to reach 36, so:
4+4+4+4+4+4+4+4+4=36 which means that:
36/4=9
Step 5: put together the two resulted numbers calculated in step 1, which is 1, and step 4, which is 9:
1 and 9 giving 19, so the answer is:
76/4=19.
In conclusion the answer is C. 19.
Ant's mass: 4 x 10 - 3
Elephant's mass: 8 x 106
First, we should evaluate these expressions by using PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. From P to S is the order that we must follow these steps.
So first for the ant's mass, we have to multiply first since the M comes before the S, resulting in 40 - 3 grams.
Next we have to subtract, leading us to getting 37.
For the elephant since there is only one operation, all we have to do is multiply, which equals 848.
In order to see how many times larger the elephant is than the ant, we have to divide the elephant's mass by the ant's.
848/37 = 22.9
Since you only want an approximate answer, you can put down 23 or even go a bit more vague and put down 20.
The area would be 132cm^2 (squared)
(9x4)x2+(7+8)x4 =132
The perimeter you just add everything up so it’s 65cm
15+13+4+7+9+4+13
Answer: 49/9
Step-by-step explanation:
9x5=45
45+4=49
