Step-by-step explanation:

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answer: Not what's written down.

Step-by-step explanation:

Okay, so basically, if you have a letter, no other number can go with that number with a letter. So like 5x + 2b -7.

There is only one number that has x, so 5x.

Same with b. 5x + 2b.

Now, there is no letter with the 7, so that will stay the same.

So, the answer is 5x + 2b -7.

Now, I look at your question.

If I do all of the work I just showed, the answer is C.

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Answer:

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Step-by-step explanation:

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

best describes the location of the polar easterlies?

Step-by-step explanation:

Polar easterlies The polar easterlies (also Polar Hadley cells ) are the dry, cold prevailing winds that blow from the high-pressure areas of the polar highs at the north and south poles towards low-pressure areas within the Westerlies at high latitudes. [ 1 ]

hope this helped :)

Among all the given descriptions, the one that describes the location of the polar easterlies is: “60 to 90 degrees north and south latitude.” Hence, Option A is correct.

Dry, chilly polar easterlies are the dominant winds that originate in the east. They come from the polar highs, which are pressure ridges located around the North and South Poles.

Low-pressure zones in subpolar regions receive polar easterlies. At midlatitudes, the dominant winds are westerlies, which originate in the west.

Polar easterlies are the cold, dry, and dominant winds that surround the high-pressure zones of the polar highs at the North and South Poles in the study of Earth's atmosphere.

The constant winds that blow in the middle latitudes are known as westerlies. They blow in the direction of subpolar low pressure belts from subtropical high pressure belts.

Compared to the westerlies in the Northern hemisphere, the westerlies in the Southern hemisphere are stronger and more reliable.

Therefore, Option A is correct.

Answer:

y=60° b=60°

Step-by-step explanation:

the sum of all degrees of interior triangle is 180

in the first one, 30° and 90° have been given.(that small square represent 90°)

so 180°-90°-30°=60°

in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°

Let's take this problem step-by-step:

Both problems involve triangles:

 ⇒ let's find out the sum of the interior angle w/ formula 180(n-2)

        Total Interior Angle Sum of Triangle = 180(3-2) = 180

Let's solve the first problem (A)

   ⇒ we know the total interior angle sum is 180 degrees

   ⇒ we know that two of the angles are 30 degrees and 90 degrees

        * any angle with a square on them is 90 degrees

   ⇒ therefore:

           30 + 90 + y = 180

              120 + y= 180

                    y = 60

Let's solve the second problem:

  ⇒ the angle opposite the exterior angle, 120 degrees, is on a flat line

        with it

        ⇒ therefore it is 60 degrees

            ⇒ two angles on a flat line equal 180 degrees

   ⇒ two angles are therefore 60 degrees

    ⇒ therefore:

                     60 + 60 + y = 180

                          120 + y = 180

                                  y = 60

Answer:

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.
