Which system of inequalities is shown?

a.y > x
y > 2

b. y > x
y < 2

c. y < x
y < 2

d. y < x
y > 2

Answers

Answer: Choice C

y < x

y < 2

==================================================

Explanation:

The horizontal line is y = 2 since all points on this line have a y coordinate of 2. Eg: (0,2) and (5,2)

Since we shade everything below this line, we're describing the inequality y < 2. All points in the shaded region for this describe anything with a y coordinate smaller than 2. Eg: (7,1)

-------------

At the same time, we're also shading below the line y = x to form the inequality y < x.

So that's how we end up with this system

[tex]\begin{cases}y < x\\y < 2\\\end{cases}[/tex]

which describes the set of all points below the lines y = 2 and y = x. The dashed lines indicate that points on the boundary do not count as solution points. For example, (5,2) is not a solution because it rests on the upper horizontal boundary.

What is the quotient of 1.155 x 10^5 and 1.65 x 102 expressed in scientific
notation?

Answers

Answer: 7.00x10^2

Step-by-step explanation:

Are you asking for the quotient of (1.155 x 10^5)/(1.65 x 10^2)?

If so, divide (1.155/1.65) = 0.7000.

Then subtract 2 (the bottom exponent from [tex]10^{2}[/tex]) from the top exponent:  [tex]10^{5}[/tex] becomes [tex]10^{3}[/tex].

Combine the two:  0.7000x10^3

Move the decimal point to the right by one:  7.00x10^2 (to 3 sig figs).

7 x 10² is the quotient of 1.155 x 10⁵ and 1.65 x 10² expressed in scientific

notation.

To find the quotient of these two numbers in scientific notation, you divide the two significant figures and then subtract the exponents of 10. The calculation would be as follows:

(1.155 x 10⁵) / (1.65 x 10²)

Dividing the significant figures:

1.155 / 1.65

= 0.7

Subtracting the exponents:

5 - 2 = 3

So, the quotient in scientific notation is approximately:

0.7 x 10³

Which can also be written as:

7 x 10²

Hence, the quotient of 1.155 x 10⁵ and 1.65 x 10² expressed in scientific

notation is 7 x 10².

An infant drinks about 30 ounces of milk per day. About how many quarts of milk does the baby drink in 4 weeks

Answers

Answer:

840 Ounces

Step-by-step explanation:

4 weeks has 28 days. { 4 * 7 = 28 }

because an infant eats about 30 ounces of milk per day.

So 30 * 28 = 840 ounces

The baby drank about 840 ounces in 4 weeks.

The number of quarts of milk drank by baby in 4 weeks is 26.25 quarts.

Given that, an infant drinks about 30 ounces of milk per day.

What is metric conversion?

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

Here, number of days in 4 weeks = 4×7

= 28 days

Number of ounces of milk drank by infant

= 28×30

= 840 ounces

We know that, 32 ounces = 1 quarts

So, 840 ounces = 840/32

= 26.25 quarts

Therefore, the number of quarts of milk drank by baby in 4 weeks is 26.25 quarts.

Marlee has to find the point that divides the line segment between the points P(-6, 10) and R(2, -4) exactly in half. Marlee states: "the answer is M(-2, 3). Since a midpoint divides a line segment into 2 equal parts, I used the midpoint formula." Is this a logical argument?

Please choose one of these choices.:

A. Yes; using the midpoint formula will determine the middle point of a line segment.
B. No; she should have used the distance formula.
C. No; she should have used the quadratic formula.
D. No; she should have used the slope-intercept formula y = mx + b.

Rickets Vitamin D is essential for strong, healthy bones. Our bodies produce vitamin D naturally when sunlight falls upon the skin, or it can be taken as a dietary supplement. Although the bone disease rickets was largely eliminated in England during the 1950s, some people there are concerned that this generation of children is at increased risk because they are more likely to watch TV or play computer games than spend time outdoors. Recent research indicated that about 20% of British children are deficient in vitamin D. Suppose doctors test a group of elementary school children.

child is the eighth one tested?
b) What’s the probability that the first 10 children tested

By now, the growl coming from Marcel's stomach was audible to his friends. Claudette had been asking for pizza this entire time, but Pablo would not budge. He repeatedly told them that they always settle for pizza, and this time he wanted to try the new Italian cafe and he would not budge for anything but cafe food. Marcel, tired of being interrupted by his gut, began to counter that a cafe did not have meal-sized portions, and by now he had gone from slightly hungry to extremely ravenous. However, Pablo and Claudette seemed to ignore Marcel's input and continued to bicker between the only two options they cared to consider. Then Marcel had a marvelous idea. First, he allowed his friends to tire themselves out arguing for a bit longer. When they finally took a breath, Marcel saw his chance. "You know, there is a new restaurant down the street, which offers a buffet where we can get pizza, cafe food, and anything else we might want." As expected, Pablo and Claudette used Marcel's talking point as a chance to catch their breath before going back to talking over one another. Pablo had been giving in to Claudette and her need for pizza for months now. It was always pizza because pizza was never an option at home and he knew this. Eating with Pablo and Marcel was Claudette's one time to eat something a little less healthy, so she was adamant to eat pizza. Claudette and Pablo were both stubborn, so when Marcel offered up the chance to try a new place that would satisfy what everyone wanted, it went in one ear and out the other. Marcel was prepared for this, but he also knew his two friends often had a delayed reaction to good news when they were arguing amongst themselves. After a few more minutes of going back and forth, Claudette and Pablo suddenly stopped. They both turned to Marcel, as if they just had a new idea."Hey, there is that new buffet place. Isn't it just down the road?" Marcel smiled as Pablo and Claudette came to an agreement to give the buffet places a try. As Claudette led them out the door, Marcel hid a smile.2Drag the tiles to the correct boxes to complete the pairs.Match the characters to the ways they develop the plot.MarcelPabloClaude PLEASE HELP ME ASAP Anna is working as a teller at a bank.
