You order office supplies for your company every quarter. The invoices for the first three quarters are $615, $791, and $803. What was the total amount spent on office supplies for the first three quarters?

Answer:

we need to shift decimal then divide

Step-by-step explanation:

First we move the divisor (if its a decimal) to the right until there is no more dot. If your dividend is also a decimal you also need to move it to the right how many spaces you moved the divisor's.

Example:

923.56 ÷ 4.5

This means that we move the dot between 4 and 5 once. We do the same to 923.56.

This means our division problem will be

9235.6 ÷ 45.

Now just do the problem normally as you should.

Answer:

10cm 5cm and 9cm

Step-by-step explanation:

just try this

take any two measurements and add them together if they are larger than the 3rd measurement it will work and all you have to do is do that to each measurement

10+5 is greater than 9

9+5 is greater than 10

9+10 is greater than 5

Answer:

=-4/2

Step-by-step explanation:

xp=x1 +k (x2-x1)

=-3+1/3 (2- -3)

=-3 + 1/3  (5/1)

= -3 + 5/3

= -9/3 +5/3

= -4/2

Step-by-step explanation:

Step-by-step explanation:

Hey there!

The equation of a st.line passing through point is;

(y - 8) = m1(x+4).........(i).

And another equation is;

3x - 8y - 7 =0.......(ii)

From equation (ii), we get;

[tex]slope(m2) = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]

[tex]m2 = \frac{ - 3}{ - 8} [/tex]

Therefore the slope is 3/8.

As they are parallel lines, their slopes are eaual.

i.e m1 = m2 = 3/8.

Putting value of slope (m1) in equation (i).

[tex](y - 8) = \frac{3}{8} (x + 4)[/tex]

Simplify them to get equation.

[tex]8(y - 8 ) = 3x + 12[/tex]

[tex]8y - 64 = 3x + 12[/tex]

[tex]3x - 8y + 12 + 64 = 0[/tex]

[tex]3x - 8y + 76 = 0[/tex]

Therefore therequired equation is 3x - 8y +76=0.

Hope it helps...

Answer:

mean: 20

minimum: 5

range:45

median:16.5

Answer:

5

Step-by-step explanation:

When we have an equation in slope-intercept form, it's put in the form

[tex]y = mx+b[/tex]

Where m is the coefficient (the slope) and b is the y-intercept.

Since we are trying to find the y-intercept based on this equation (that's why it says [tex]b=[/tex] ), we can use the equation to find the y-intercept.

The slope is [tex]\frac{1}{3}[/tex] since that's the coefficient next to x.

The constant being added is 5, therefore this is the y-intercept.

Hope this helped!

Complete question :

Point K on the number line shows Kelvin's score after the first round of a quiz: A number line is shown from negative 10 to 0 to positive 10. There are increments of 1 on either side of the number line. The even numbers are labeled on either side of the number line. Point K is shown on 3. In round 2, he lost 9 points. Which expression shows how many total points he has at the end of round 2? 3 + (−6) = −9, because −9 is 6 units to the left of 3 3 + 6 = −9, because −9 is 6 units to the left of 3 3 + (−9) = −6, because −6 is 9 units to the left of 3 3 + 9 = −6, because −6 is 9 units to the left of 3

Answer: 3 + (−9) = −6, because −6 is 9 units to the left of 3

Step-by-step explanation:

Given the following :

Width of number line = - 10 to + 10

Point K on the number line = +3 ( kelvin's score after the first round of quiz).

If Kelvin losses 9 points in round 2  = - 9

Hence at the end of round 2, He'll have a total of :

Point at the end of round 1 + point lost in round 2

3 + (-9) = - 6

Answer:

Answer:

19 and 20

Step-by-step explanation:

Let x be the larger number

x - 1 + x = 4x - 41

We can combine like terms and isolate x:

2x - 1 = 4x - 41

2x = 40

x = 20

20 - 1 = 19

Answer: B. In a very large? study, it was found that Treatment I resulted in? 93% success while Treatment II resulted in? 75% success.

Step-by-step explanation: The significance of a treatment, process or procedure in terms practicality lies in the logical assessment of such process as to whether it has a tangible or worthwhile impact. Based on the list of treatments or experiments above, the treatment which could be considered to have had a huge or significant impact is that which has 93% and 75% success rate on treatment 1 and 11 respe tivwly having considered that the study was said to be a very large one. Hence, going by large number of participant involved and a success rate with such high percentage, then the study could be said to possess practical significance.

The result that would be considered practically significant is: B. In a very large study, it was found that Treatment I resulted in? 93% success while Treatment II resulted in? 75% success.

A significant result is that in which the outcome cannot be based on chance. Such a result satisfies all conditions required and leaves no room for doubt.

The result obtained above can be deemed to be statistically significant because a very large percentage of the two treatments achieved the purpose for which they were engineered.

The success is very significant and cannot be attributed to mere chance.
