Answer:

The difference in the amounts of carbon powder and ammonium carbonate is \(88.3\times 10^{-6}\) grams.

Step-by-step explanation:

According to this statement, we have a mixture with \(3.7\times 10^{-6}\) grams of carbon powder and \(92\times 10^{-6}\) grams of ammonium carbonate. The difference between those amounts consist in subtracting the latter quantity for the former one. That is:

\(\Delta m = 92\times 10^{-6}\,g \,-\,3.7\times 10^{-6}\,g\)

\(\Delta m = 88.3\times 10^{-6}\,g\)

The difference in the amounts of carbon powder and ammonium carbonate is \(88.3\times 10^{-6}\) grams.

# of large ice creams: 240/3 = 80

# of small ice creams: 240 - 80 = 160

Total large ice cream cost: 80*3.8 = 304

Total small ice cream cost: 640 - 304 = 336

Cost of one small ice cream: 336/160 = 2.1

To find the percent that the family spent on the rent and utilities, you first add the utilities and rent amount, $225+$875 = $1100

After this you try to find the total sum of everything in the pie chart which adds up to $2432.50.

Finally, in order to calculate the percentage:

1100 ÷ 2432.50 × 100

Answer:

10.8 mi

Step-by-step explanation:

Picture a right triangle with legs 9 mi and 6 mi.  Applying the Pythagorean Theorem (d² = a² + b²), we get:

(9 mi)² + (6 mi)² = 117 mi²

This is the square of the hypotenuse (the desired distance).

Taking the square root of both sides, we get d = √(117 mi) ≈ 10.8 mi = d

The desired straight line distance traveled is 10.8 mi

Answer:

The point of intersection between 2x+3y=12 and 2x-y=4 is (3,2)

Step-by-step explanation:

Using the continuity concept, since the lateral limits and the numeric value of the function are equal at the point in which the definition changes, the function is continuous.

A function f(x) is continuous at x = a if it is defined at x = a, and:

\(\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)\)

The definition of the piecewise function is given by:

Since the definition of the function changes at x = 2, and the domain of the function has no restrictions, this is the only point in which there may be a discontinuity.

The lateral limits are:

The numeric value is:

f(2) = 1.5 x 2 = 3.

Since the lateral limits and the numeric value of the function are equal at the point in which the definition changes, the function is continuous.

The smallest distance of the line to the point is of:

5.36 units.

Suppose the line is defined as follows:

ax + by + c = 0.

The coordinates of the points are as follows:

(x0,y0).

Then the shortest distance of the point to the line is:

D = |a(x0) + b(y0) + c|/sqrt(a²+b²).

In this problem, the line goes through these two points:

(2/7, 3) and (-2,11).

The slope is given by the change in y divided by the change in x, hence:

m = (11 - 3)/(-2 -2/7) = -3.5.

Then:

y = -3.5x + b.

When x = -2, y = 11, hence the intercept is calculated as follows:

11 = -3.5(-2) + b

11 = 7 + b

b = 4.

Then the line is:

y = -3.5x + 4.

3.5x + y - 4 = 0. (standard format, a = 3.5, b = 1).

The coordinates of the point are as follows:

(x0,y0) = (-3,-5).

Then the shortest distance is:

D = |3.5(-3) + 1(-5) - 4|/sqrt(3.5²+1²).

D = 19.5/sqrt(3.5²+1²).

D = 5.36 units.

This is a ratio problem, the ratio of  cars to trucks

for every 4 cars, there are 6 trucks

represented as a ratio we have 4:6

1. how many of them are cars

applying the part to whole strategy we have

4+6 = 10

let cars be x

\(\frac{4}{10}= \frac{x}{220} \\\\x= \frac{220*4}{10} \\\\x= 880/10\\\\x= 88 cars\)

Answer:

(x + 3)² + (y - 1)² = 80

Step-by-step explanation:

Circle equation: (x - h)² + (y - k)² = r²

We are given h and k, so we just plug that in:

(x + 3)² + (y - 1)² = r²

To find r, we need to use distance formula: \(d = \sqrt{(x2-x1)^2+(y2-y1)^2}\) between the center of the circle and the point on the circle. We should get √80 as r. We plug that in to get our answer:

(x + 3)² + (y - 1)² = 80

Answer:

One pair of socks is $12.

Step-by-step explanation:

You subtract 39 from 75 and divide by 12

while the presence of only one spot on a TLC plate may suggest that the compound is pure, further analysis is needed to confirm the purity of the compound, such as melting point determination, NMR spectroscopy, or HPLC (high-performance liquid chromatography).

Using UV and seeing only one spot on a TLC (thin-layer chromatography) plate is not a definitive indicator of the purity of a product.

While it is true that a pure compound will only show one spot on a TLC plate, there are several reasons why a compound may still show only one spot even if it is not pure. For example:

The impurity may have a similar Rf (retention factor) value to the compound of interest and therefore co-migrate with it on the TLC plate, making it difficult to distinguish between the two.

The impurity may be present in such a small amount that it is not visible on the TLC plate.

The compound of interest may have multiple conformers or isomers that have the same Rf value and appear as a single spot.

Answer:

69.15% of lights will need to be replaced within 235 h.

Step-by-step explanation:

We are given that the lifetimes of a certain brand of photographic are normally distributed with a mean of 210 h and a standard deviation of 50 h.

Let X = the lifetimes of a certain brand of photographic

The z-score probability distribution for the normal distribution is given by;

                              Z  =  \(\frac{X-\mu}{\sigma}\)  ~ N(0,1)

where, \(\mu\) = population mean lifetime = 210 h

           \(\sigma\) = standard deviation = 50 h

Now, the percent of lights that will need to be replaced within 235 h is given by = P(X \(\leq\) 235 h)

      P(X \(\leq\) 235 h) = P( \(\frac{X-\mu}{\sigma}\) \(\leq\) \(\frac{235-210}{50}\) ) = P(Z \(\leq\) 0.50) = 0.6915 or 69.15%

The above probability is calculated by looking at the value of x = 0.5 in the z table which has an area of 0.6915.

Multiply the probability of each by each other:

Probability of red = 1/4

Probability of blue = 1/4

Probability of green = 2/4 = 1/2

probability of red then blue then green = 1/4 x 1/4 x 1/2 = 1/32

answer: 1/32

We have two stacks of styrofoam cups. One stack has 6 cups, and its height is 15 cm. The other stack has 12 cups, and its height is 23 cm. How many cups are needed for a stack with a height of 50 cm

Answer:

37.5 cups

Step-by-step explanation:

Height 1 = 15cm

Number of cups = 6

Height 2 = 23 cm

Number of cups = 12

Hence:

H1 - H2/N1 - N2

= 15 - 23/6 - 12

= -8/-6

= 4/3

The number of cups that are needed for a stack with a height of 50 cm is calculated as:

50 cm ÷ 4/3

= 50 × 3/4

= 37.5 cups
