A bottle of orange juice contains 750 mg of vitamin C and has 6 servings. A bottle of
Llana [10]

Answer:

The bottle of orange juice will have higher amounts of vitamin C per serving, as it will have 125 mg against 90 mg of the cranberry juice.

Step-by-step explanation:

To determine the amount of vitamin C in each serving of fruit juice, knowing that the bottle of orange juice contains 750 mg of vitamin C and 6 servings, while the bottle of cranberry juice contains 135 mg and 1.5 servings, you must perform the following calculation:

Orange: 750/6

Orange: 125 mg per serving

Cranberry: 135 / 1.5

Cranberry: 90 mg per serving

Thus, the bottle of orange juice will have higher amounts of vitamin C per serving, as it will have 125 mg against 90 mg of the cranberry juice.

An automobile with 0.279 m radius tires travels 65000 km before wearing them out. How many revolutions do the tires make, neglec
bija089 [108]

Answer:

Revolutions=37079108.61 rev

Step-by-step explanation:

First if all we have to make the units same to calculate the revolutions

Since distance gis gien in km and radius is given in m we will covert distance to m first.

Distance =S=65000km

Distance=S=65000km*1000m/km

Distance = S= 65000000m

Formula:

S=rθ

where

S is the distance

r is the radius

θ is the revolution in radian

θ=S/r

θ=65000000/0.279

θ=232974910.4 rad

Revolutions=θ/2π

Revolutions=232974910.4/2π

Revolutions=37079108.61 rev

A set of 4 consecutive integers adds up to 202. What is the greatest of these integers?
lbvjy [14]

Answer:

52

Step-by-step explanation:

When asked such a question, try to use trial and error.

For example, the total is 202 and is made of of 4 integers which are <u>consecutive</u>(follow each other)

If you were to divide 202 by 4, you would get approximately 50

So, it would be best to try and add certain consecutive numbers(making sure 50 is one of them) till you get a total of 202

In this case, the integers would be, <em>49, 50, 51</em> and <em>52</em>

The question then further asks you ti find out which is the greatest of these integers. That would be <em>52</em>

I don't understand this very much, but if someone could give me an explanation, that would be appreciated! ×·×∡
Rama09 [41]

Answer:

<em>119.0 cm²</em>

Step-by-step explanation:

What is surface area

It is the area of the outside part of anything. Surface area is also called total surface area.

As we can see from the pyramid, it has a square base. How do I know that it is a square base, is by seeing the dimensions of the base, which are 6.4 cm by 6.4 cm in this pyramid. And we already know from basic Geometry that a square has 4 equal sides. So we call it a square pyramid.

So to find the total surface area of this square pyramid, we need the area of the 4 triangular faces and the area of the square base.

So t.s.a of the pyramid = 4 × Area of each triangular face + Area of the square base.

So, total surface area = Area of square base + Area of the four triangular faces.

     <em>total surface area</em> = (<em>length²) + (</em>4 × \frac{1}{2} × <em>base × height)</em>

<em>      t</em><em>otal surface area =</em><em> </em>(6.4 × 6.4) + (4 × \frac{1}{2} × 6.4 × 6.1)

     <em>total surface area = 40.96 + 78.08</em>

<em>      total surface area = 119.04 cm² ≈ 119.0 cm² (to the nearest tenth) (Answer)</em>
