Jackie drinks a bottle of water and a bottle of orange juice every morning the bottle of water has 16.9 the bottle of orange juice has 15.2 which is the best estimate for the total amount jackie drinks in the morning for an entire week and gives a good explanation for that estimate

Answers

Answer:

224.7cl

Step-by-step explanation:

Ok, noticed that the bottles are not properly given a unit according to the question.

let us assume the units are in centiliters that is cl

Every morning the bottle of water has 16.9cl

the bottle of orange juice has 15.2cl

therefore if Jakie does this drinking continuously for 7 days she will be drinking

bottle of water has 16.9cl*7= 118.3cl

bottle of orange juice has 15.2cl*7=106.4cl

total=118.3+106.4

total is 224.7cl

The picture shows 3 steel rods. The rods are congruent, solid cylinders. The area of the top of the one rod is 7.07 square centimeters. The area of the body of one rod is 39.58 square centimeters. Find the total surface area of the 3 rods.
a) 53.72
b) 46.65
c) 139.95
d) 161.16

Answers

Answer: D, 161.16 square centimeters.

Step-by-step explanation:

The surface area of a cylinder (shape of each steel rod) is given by this formula:

[tex]A = 2\pi rh + 2\pi r^2[/tex], where the first 2*pi*r*h measures the area of the curved surface while the second 2*pi*r^2 measures the area of the two circles on the top and bottom.

We are given the area of the top of one rod, which is 7.07 square centimeters.

We are also given the area of the body of one rod, which is 39.58 square centimeters.

The top of one rod is the shape of a circle, and we know there are two circles on both sides of a cylinder, so the surface area of both circular sides are 7.07.

The total surface area of a cylinder is the body plus both circular ends, so the surface area for this cylinder is:

39.58 + 7.07 + 7.07 = 53.72

There are three cylinders, so multiply this value by three to get the answer, 161.16 square centimeters.

What is the product of the polynomial 2x^3 + 8x^2 + x + 3 times the
monomial x?

Answers

Answer:

[tex]\huge\boxed{2x^4 + 8x^3 + x^2 + 3x}[/tex]

Step-by-step explanation:

When we multiply a polynomial by a specific monomial, all terms in the polynomial get multiplied by the monomial.

So we can do this by term.

[tex]2x^3 \cdot x[/tex]

Multiplying x by x to the something power will just increase the exponent on the x term by one (since powers are just x multiplied by itself). This means the exponent here will increase by 1, so this becomes [tex]2x^4[/tex].

Same logic applies to the second term: [tex]8x^2[/tex], raise the exponent by one, [tex]8x^3[/tex].

For the third term, if there is no exponent on a term you can assume it's exponent is 1 (so [tex]x^1[/tex] in this case - as [tex]x^1=x[/tex]). Again, using the same logic, this turns into [tex]x^2[/tex].

For the last term, when we multiply a constant by a variable, we get a term with a variable and a coefficient - the constant becomes the coefficient and the variable stays the variable. Therefore, [tex]3 \cdot x = 3x[/tex].

Adding these terms all together gets us [tex]2x^4 + 8x^3 + x^2 + 3x[/tex].

Hope this helped!

Alex can run 5/4 miles in 1/12 hour. At this rate, how far can he run in 1 hour?

Answers

Answer:

15 miles in one hour

Step-by-step explanation:

Since we know that we need twelve 1/12 hours to make one full hour, we can multiply.

5/4 * 12

5/4 * 12/1

60/4

Best of Luck!

Answer: 15 miles

If he can already run 5/4 miles in 1/12 of an hour, we multiply.

First, let's simplify 5/4 to make it easier.

5/4 = 1 1/4.

Alex ran 1 1/4 miles in 1/12 of a hour.

Now, let's multiply 1 1/4 by 12.

1 1/4 x 12 = 15.

Answer = 15 miles. Hope this helps!

• Technology Fee: $150 per semester
• Books: $310 per semester
• Plane Ticket Cost: $289 (annual cost)
Mark's total cost for s semesters of school in 4 years is represented by the expression below.
$23,556 + $3,060
Which statement best describes the constant in the expression?
It is the total cost for one semester for tuition and plane tickets.
It is the total cost for tuition, technology, and books for four years.
It is the total cost for tuition, technology, and books per semester.
It is the total cost of housing and plane tickets for four years.

Answers

Answer:

It is the total cost of housing and plane tickets for four years.

Step-by-step explanation:

Mark's costs for tuition, technology fee, and books are all per semester, s. ($2,600 + $150 + $310)s = $,060s

The cost for housing and plane tickets are a once a year cost. Mark pays these amounts once a year for four years.4($5,600 + $289) = $23,556

Therefore, the constant in the expression is $23,556, and it is the total cost for housing and plane tickets for four years.
