Convert to a mixed number:
13/3

Divide 13 by 3:
3 | 1 | 3

3 goes into 13 at most 4 times:
| | 4
3 | 1 | 3
- | 1 | 2
| | 1

Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
| | 4 | (quotient)
3 | 1 | 3 |
- | 1 | 2 |
| | 1 | (remainder)

The quotient of 13/3 is 4 with remainder 1, so:
Answer: 4 1/3

Last week, mallory flew two round trips. They were 3,720 miles and 5,985 miles. Select all of the choices that are good estimate

SVETLANKA909090 [29]

Answer:

Mallory flew in total 10,000 miles, rounded :D

Step-by-step explanation:

Since we're using rounding to place values, first we have to have the total amount of miles flown by Mallory, so we make the sum:

3,720 + 5,985 = 9,705 miles

then, we have to round thefirst digit to the right following this rule

0-4 is rounded down

5-9 is rounded up

now, since the number we want to round is the first digit on the left (9), and following the rules above, we change the "9" for a "10". the rest of the numbers are now transformed into zeros (0)

9,705 >>> rounding it up >>> 10,000

Let me know if you have any questions XD

1.Write the expression in expanded form. The subscript number can be write in

enyata [817]

Answer:

(a) Expanded form:

$((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)$

(b) The value of the expression: -21

Step-by-step explanation:

Given

$\sum \limit^4_{i=1}\ ((X_i+X_iY_i) - X_iZ_i)$

Solving (a): The expanded form:

This means that we substitute the values of i from 1 to 4 in the above expression.

So, the expression becomes:

$((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)$

Solving (b): The value of the expression

To do this, we simply substitute the given values of X1, X2....... in the expression.

This gives:

So, the expression becomes:

$((0 + 0*5) - 0*0) + ((1 + 1*26) - 1*-2) + ((12 + 12*-2) - 12*3) + ((-1 + -1*25) - -1*24)$

Simplify each bracket

$((0 + 0) - 0) + ((1 + 26) +2) + ((12 -24) - 36) + ((-1 -25) +24)$

$0 + 29 -48 -2$

$-21$

Hence, the result of the expression is -21

Help me with this question

kirill115 [55]

Answer:

Step-by-step explanation:

This is an even polynomial because both ends end up. This means the degree of the polynomial is even. This means b and c are not solutions since their degrees are odd.

To determine between A and D look at the x-intercepts. The x-intercepts of a polynomial graph have a special relationship with its equation. The x-intercepts are the solutions or roots of the factors. This means that when each factor is set equal to 0 and solved, its solution is an x-intercept. Here the x-intercepts are x = -1, 0,3. This means the factors are x(x+1)(x-3).

Notice at x = -1, the function touches but does not cross? This means the factor has an even exponent on it.

So the expression is likely x(x+1)^2 (x-3).

Since only one factor has an exponent, the answer is A.
