On a trip to California, Hayley mined 30 ounces of gold. Kara mined 6 ounces of gold. Who found more gold and by approximately how much?

Step-by-step explanation:

Distribute the negative sign to each term inside the parenthesis.

- (9k-5p+7e-2)

To distribute the negative sign to each term inside the parenthesis:

a negative and positive = -

a positive and positive = +

a negative and negative = +

- (9k-5p+7e-2)

- 9k + 5p - 7e + 2

Step-by-step explanation:

(-9k+5p-7e+2)

-×-=+

-×+=-

+×+=+

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

9.1

Step-by-step explanation:

For scale factor you divide one of the shape dimensions by the other one.

like if you knew the width or something of both of them you divide that one by the other one. So I chose:

                            91 divided by 10 = 9.1

                         81.9 divided by 9 = 9.1

                        54.6 divided by 6 = 9.1

          So the answer is 9.1 no matter what you choose for this problem.

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

341/11 = 31 is the arithmetic mean.

Step-by-step explanation:

It could be wrong but I'm pretty sure I'm right.

For 1 pound of flour you cant make any batches or .083 of a batch.

For 34 pounds you can make 2.833 batches.

And finally, 14 pounds of flour gives you 1.166 batches.

To find these answers take your amount of flour and divide it by the 12 pounds of flour.

Example; 34 divided by 12 = 2.833

Example 2; 14 divided by 12 = 1.66

Answer:For 1 pound of flour you cant make any batches or .083 of a batch.

For 34 pounds you can make 2.833 batches.

And finally, 14 pounds of flour gives you 1.166 batches.

Answer: 8.5

Step-by-step explanation: 8.5 because 34 divided by 4 is 8.5. To find the unit rate, make 4 hours turn to 1 hour. To do that, divided 4 by 4. Do the same with the other number, which is 34. 34 divided 4 is equal to 8.5

Answer:

Answer:

 -4 -6 2 -2x 3-4x 2x-3

Step-by-step explanation:

3 - 7= -4 (7 is larger so we get - sign)

-4-2=-6(we add "-" terms but they have the - sign)

-4-(-6)=-4+6=2(- multiplied by - =+ meaning - - = +)

x-3x=-2x(3x is larger)

3-4x=3-4x(Unlike Terms)

-3 - (-2x)=-3+2x=2x-3(Unlike terms, so we only simplify the signs)

Answer:

Step-by-step explanation:

\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\\\)

\(\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\)

\(\frac{1}{3} x + -2 + \frac{1}{2} x + 6 = 3\)

\(5/6 x + 4 = 3\)

\(5/6x + 4−4= 3−4\)

\(5/6x = −1\)

\((6/5) * (5/6x) = (6/5) * (−1)\)

\(x=−6/5\)

Answer:

- 938

Step-by-step explanation:

We can change these to positive just so its easier to work with

So 1360 - 422 = 938

since they are going down you just have to change the number to a negative.

The change in elevation is 938 feet.

To find the change in elevation.

The action or fact of raising or being raised to a higher or more important level, state, or position. Elevation is distance above sea level. Elevations are usually measured in meters or feet. They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface.

Given that:

Dead sea is at an elevation = -1,360 feet.

seabirds flying over the dead sea at an elevation =-422 feet.

Although when you have 2 negative numbers in a subtraction-elevation problem, the elevation difference won't be negative.

So, difference between the depth and the surface of the dead sea

= Dead sea is at an elevation - seabirds flying over the dead sea at an elevation

=-1360-(-422)

=-938 feet.

But that would just describe a regular negative subtraction problem, so it becomes 938 feet.

This answer is positive since it describe the distance between these integers.

So, the change in elevation is 938 feet.
