Answer:

Marissa did not change the direction of the inequality sign.

Step-by-step explanation:

Hello!

We can solve the inequality as well, and compare our steps to Marissa's to verify her steps.

We have the same number, but a different inequality sign. This is because we have to flip the inequality sign when multiplying and dividing by a negative number.

Therefore, the answer is the last option, Marissa has to flip the inequality sign when multiplying by a negative number.

The unit rate of the lemonade is $0.2 per ounce.

A unit rate means a rate for one of something.

Given that, Justin sells 78.5 ounces of lemonade for a total of $15.70.

We are asked to find the unit price in dollars per ounce.

Since, he sells 78.5 ounces in $15.70

So, in one ounce will be sold in = 15.70 /78.5 = 0.2

Hence, the unit rate of the lemonade is $0.2 per ounce.

Answer:

Mars: 1) Named after the Roman God of war, Mars is the fourth planet from the sun in our solar system. 2) Mars is also known as the 'Red Planet' because, well, it's red! This signature colour comes from the large amount of a chemical called iron oxide (or 'rust' as you might know it) in its rocks and soil.

Pluto: 1) Pluto is named after the Roman god of the underworld.  2) Pluto was reclassified from a planet to a dwarf planet in 2006.  3) Pluto was discovered on February 18th, 1930 by the Lowell Observatory.  4) Pluto has five known moons.  5) Pluto is the largest dwarf planet.  6) Pluto is one third water.

Hope these help!!

Pluto

Pluto is named after the Roman god of the underworld.

This was proposed by Venetia Burney an eleven year old schoolgirl from Oxford, England.

Pluto was reclassified from a planet to a dwarf planet in 2006.

This is when the IAU formalised the definition of a planet as “A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.”

Pluto was discovered on February 18th, 1930 by the Lowell Observatory.

For the 76 years between Pluto being discovered and the time it was reclassified as a dwarf planet it completed under a third of its orbit around the Sun.

Pluto has five known moons.

The moons are Charon (discovered in 1978,), Hydra and Nix (both discovered in 2005), Kerberos originally P4 (discovered 2011) and Styx originally P5 (discovered 2012) official designations S/2011 (134340) 1 and  S/2012 (134340) 1.

Pluto is the largest dwarf planet.

At one point it was thought this could be Eris. Currently the most accurate measurements give Eris an average diameter of 2,326km with a margin of error of 12km, while Pluto’s diameter is 2,372km with a 2km margin of error.

Pluto is one third water.

This is in the form of water ice which is more than 3 times as much water as in all the Earth’s oceans, the remaining two thirds are rock. Pluto’s surface is covered with ices, and has several mountain ranges, light and dark regions, and a scattering of craters.

Pluto is smaller than a number of moons.

Mars

Mars and Earth have approximately the same landmass.

Even though Mars has only 15% of the Earth’s volume and just over 10% of the Earth’s mass, around two thirds of the Earth’s surface is covered in water. Martian surface gravity is only 37% of the Earth’s (meaning you could leap nearly three times higher on Mars).

Mars is home to the tallest mountain in the solar system.

Olympus Mons, a shield volcano, is 21km high and 600km in diameter. Despite having formed over billions of years, evidence from volcanic lava flows is so recent many scientists believe it could still be active.

Only 18 missions to Mars have been successful.

As of September 2014 there have been 40 missions to Mars, including orbiters, landers and rovers but not counting flybys. The most recent arrivals include the Mars Curiosity mission in 2012, the MAVEN mission, which arrived on September 22, 2014, followed by the Indian Space Research Organization’s MOM Mangalyaan orbiter, which arrived on September 24, 2014. The next missions to arrive will be the European Space Agency’s ExoMars mission, comprising an orbiter, lander, and a rover, followed by NASA’s InSight robotic lander mission, slated for launch in March 2016 and a planned arrival in September, 2016.

Mars has the largest dust storms in the solar system.

They can last for months and cover the entire planet. The seasons are extreme because its elliptical (oval-shaped) orbital path around the Sun is more elongated than most other planets in the solar system.

On Mars the Sun appears about half the size as it does on Earth.

At the closest point to the Sun, the Martian southern hemisphere leans towards the Sun, causing a short, intensely hot summer, while the northern hemisphere endures a brief, cold winter: at its farthest point from the Sun, the Martian northern hemisphere leans towards the Sun, causing a long, mild summer, while the southern hemisphere endures a lengthy, cold winter.

Answer:

70

Step-by-step explanation:

y=4. So replace y with 4. Your new equation is:

5 · 4² - 10

You can use basic math to finish the equation.

5 · 16 - 10

80 - 10

70

Answer: 70

Step-by-step explanation:

Substitute 4 for y in the expression (since y = 4)

Use PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction)

5 * (4)^2 - 10

= 5 * 16 - 10             Evaluate the exponent first

= 80 - 10                 Then multiply 5 and 16

= 70                         Finally, subtract

The measure of the angle will be equal to 58°.

The supplementary angles are defined as the angles whose sum is equal to 180°

here the angle is 122° degrees more than its supplementary angle.

We know that the sum of the two supplementary angles is given as:-

Suppose the known and the unknown angles are A and B respectively.

∠A  +  ∠B  =  180°

122  + ∠B  = 180°

∠B  =  180-122= 58°

Hence the measure of the angle will be equal to 58°.

Answer:

A

If it is right, then give me a brainllest okay?

Answer:

16%

Step-by-step explanation:

first you have to find out how many boxes are in the sample (count the dots - 25) Then you do 4/25 to find the percentage because there are 4 that have 48 raisins (.16) and move the decimal point to the left 2 (multiply by 100)

Answer:

a

Step-by-step explanation:

4 boxes are full of 48 raisins. 25 boxes total.

4/25 = 0.16

Convert 0.16 into a percentage by multiplying by 100.

0.16*100 = 16

so it should be 16%, correct me if wrong though.

Answer:

Yes.

Step-by-step explanation:

Use the Pythagorean Theorem and Pythagorean triples.

One commonly used Pythagorean triple is 3, 4, 5.

24 is a multiple of 3 (3*8=24), 32 is a multiple of 4 (4*8=32), and 40 is a multiple of 5 (5*8=40). This concludes that the numbers 24, 32, and 40 can be the lengths of the three sides of a right triangle.

To further check our response, we can use the Pythagorean Theorem.

a^2+b^2=c^2

24^2+32^2=40^2

576+1024=1600

1600=1600

Our response is correct.

Step-by-step explanation:

Answer:

y = 3

x = 1

y = 1.5

x = 2

Step-by-step explanation:

For the first x point, look at the graph where x is 0. When x is 0, y is 3. So the first one is 3. For the second one, there is a point on the graph where y is 4. Where y is 4, x is 1, so you the second answer is 1. For the third one, find the y point where x is -1. At the x value, -1, y is 1.5. For the last one, where y is 5, x is 2.

y is 3

x is 1

y is 1.5

x is 2

Answer:

Row 1: x=3; Row 3: y=18

Step-by-step explanation:

So to do this, look at where the line passes each of the x and y values it asks for within the graph.

In this question, x is the gallons of milk and y is the cost.

With the first part, it calls for the x value for when the y value is 6 dollars. With this, see where the line on the graph crosses 6 dollars. After doing this, you would see that the line passes over 6 dollars for when 2 gallons of milk are present. With this, write 3 under x.

With the other part, you do the same thing but now with the gallons of milk that are bought. So going up from where it says 6 gallons of milk on the graph, the line passes this over where it says $18. With this, write 18 under y.
