Which ratio is higher 15:20 or 12:16. for 35 points

Mathematics
1 answer:
Margarita [4]4 years ago
8 0

To find which ratio is higher, we can first convert the ratios into fractions (that makes it easier, at least for me) and then simplify the fractions and see which one is greater.

Since ratios are basically division, 15:20 = \frac{15}{20}, and

12:16 = \frac{12}{16}

Now we simplify these fractions. 15 and 20 have a GCF of 5, so taking out the common number gives us the simplified fraction of \frac{3}{4}.

12 and 16 have a GCF of 4, so taking out the common number gives us the simplified fraction of \frac{3}{4}. Since \frac{3}{4} = \frac{3}{4}, these ratios are the same.

On the dietitians beverage tray are 16 filled six ounce glasses. Four glasses contain prune juice and two glasses contain apple
zubka84 [21]

Answer:

\frac{5}{8}

Step-by-step explanation:

Given:

Total number of glasses = 16

Number of glasses containing prune juice = 4

Number of glasses containing apple juice = 2

To find:  fractional part of the glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice

Solution:

A fraction refers to the parts of a whole. In a fraction, a top number is the numerator, and a bottom number is the denominator.

Number of glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice = 16 - 4 - 2 = 10

Total number of glasses = 16

So,

Fractional part of the glasses that contain beverages ( perhaps, H2O) other than prune juice and apple juice = \frac{10}{16}=\frac{5}{8}

Is it one of this <br> 60<br> 50<br> 45<br> 35
dangina [55]
Non of the above. The answer is 40 and I’m sticking to my guns !

Similar meaning you can assume they are proportionate and if every side is doubled then you should double the last. Another way is to use Pythagorean’s theorem and disregard the little triangle completely.


Both ways have me 40 !

Can somebody teach me inscribed angles! My 40 question summarize on circles in geometry is today and I need help on everything!
deff fn [24]

Inscribed angles are pretty easy, they're always half the corresponding central angle.  The arc measure are always of central angles.

1. We're told to arc is 62 degrees so the inscribed angle is half,

WXY = 31 degrees.

2. Here we're told the inscribed angle is 113 degrees so the arc is double,

DGF=226 degrees

3. Angles which subtend a diameter are always right angles.

PQR = 90 degrees

4. If we draw DC we see it's a radius too, so DC=DB and we have an isosceles triangle so DCB=47 degrees so BDC=180-47-47=86.  The central angle is the arc measure so

BC=86 degrees

5. Angle JNK=53 degrees and angles NJK=NKJ because we have an isosceles triangle, two sides radii.  So NKJ=(180-53)/2.

Similarly NKL=(180-65)/2

So angle JKL=NKJ+NKL=180 - (65+53)/2 = 180 - 118/2 = 121 degrees

I better leave the rest for you.
