Answer: 1 2/3

Step-by-step explanation:

What you end up with, in this case, is 5/3=1 with a remainder of 2. The whole number you came up with (in this case "one") goes in front of the fraction in your answer. To get the fraction part, take the remainder and stick it on top of the denominator (which in this case is 3.) The answer you end up with is 1 2/3.

Step-by-step explanation:

The total amount of rice that the chef bought is 8 6/10

The chef brought 3/2 pounds of white rice

The chef also brought 71/10 pounds of brown rice

Therefore the total amount can be calculated as follows

3/2 + 71/10

= 15 + 71/10

= 86/10

= 8 6/10

Hence the total number of rice bought by the chef is 8 6/10

Answer:

$75

Step-by-step explanation:

note that 40 = 5 × 8

Given the cost of 8 then 40 will cost 5 times as much , that is

cost of 40 = 5 × $15 = $75

The time that rocket will hit ground is 8.196 seconds.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x² (a ≠ 0) for an equation to be a quadratic equation.

Given equation y = -16x² + 121x + 83

let y be the from ground and x be the time,

the time when rocket hit ground y = 0

-16x² + 121x + 83 = 0

solving using quadratic formula

x = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex])/2a

here a = -16, b = 121 and c = 83

[tex]\sqrt{b^{2} - 4ac}[/tex] = [tex]\sqrt{121^{2} - 4(-16)(83) }[/tex]

= [tex]\sqrt{14641 + 5312}[/tex] = 141.25

x = -(-121 + 141.28)/32 = -0.633

x = -(-121 - 141.28)/32

x = 8.196 second

Hence the time is 8.196 seconds.

Answer:

3 dimes

Step-by-step explanation:

Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)

Part B: Plug in what you DO know and solve the one you DON’T:

0.10x + 0.25(2) = 0.80

0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:

0.10x = 0.30 (Divide both sides by 0.10)

x = 3

Answer:

[tex]-\frac{41}{36}[/tex]

Step-by-step explanation:

To add or subtract fractions, we need to make their denominators equal. To do so, we find the Least Common Denominator (LCD), then rewrite the fractions in the equation with that denominator.

The LCD of 9 and 12, the denominators, is 36 because [tex]9*4=36[/tex] and [tex]12*3=36[/tex].

Thus:

[tex]-\frac{5*4}{9*4} =-\frac{20}{36}[/tex] and [tex]-\frac{7*3}{12*3} =-\frac{21}{36}[/tex]

Now, add the fractions together.

[tex]-\frac{20}{36} -\frac{21}{36} =-\frac{20+21}{36} =-\frac{41}{36}[/tex]

Thus, the answer is [tex]-\frac{41}{36}[/tex].

Step-by-step explanation:

Asserting a cause - and - effect relationship with highly correlated variables may sometimes be misleading due to the presence of a possible lurking or confounding variable.

Lurking variables cause unintended or spurious association between correlated variables. In the scenario described, a possible confounding variable may be weariness or Fatigue which whereby the mother finds it easier to bottle feed as they have become psychologically disturbed and are prone to be more receptive during these period.

Hence, fatigue is a possible lurking variable in this scenario.

Step-by-step explanation:

doing the cumulative. have a good day or night

The initial value is $6 which shows the cost of the catalog.

The number of observations in a data set that are above (or below) a specific value can be found using cumulative frequency. A frequency distribution table, which can be created using stem and leaf plots or directly from the data, is used to compute the cumulative frequency.

We have the table

x     y

1      $10

2      $14

3       $18

4       $22

Now, to find the initial value we have to calculate the Cumulative Frequency as

x       y           CF

1      $10         10

2      $14         4

3       $18        4

4       $22       4

So, the initial value is
