What's the answer to problem 19 Geometry?
First, write the equation of the line.
<u>Let's find the y-intercept.</u>
- => y = mx + b
- => y = mx + 5
Now, let's find the slope.
- My chosen points: (1,2) and (-1,2)
<u>Finding the slope:</u>
Our equation: y = -3x + 5
Now, let's <u>change</u> the sign to <u>"≤"</u> because that will tell us the area of the <u>gray region.</u> If we were using the sign <u>"≥"</u>, that would find the area of the <u>blue region.</u>
Linear inequality = <u>y ≤ -3x + 5</u>
Option B is correct.
Answer:the answer to this question is C (16,12)
Step-by-step explanation:
Answer:
7238 rounded to the nearest whole number.
Step-by-step explanation:
To find the volume of the sphere, we use the formula.
The radius will be 24 units ÷ 2 = 12 units.
Hence, the volume is
When entered in a calculator you'll get a result of 7238.23 cubic units in or 7238 rounded to the nearest whole number.
Answer:
11:18
Step-by-step explanation:
Here, we are interested in calculating the ratio of diameter of ball A to that of ball B
what to do here is to ensure that both diameters have measurements that are same units.
Thus, mathematically;
44 mm to 7.2cm
But, mathematically;
10 mm = 1 cm
Thus 7.2cm = 7.2 * 10 = 72mm
Thus, our ratio becomes;
44:72
divide through be 4, we have
44/4 : 72/4
= 11 : 18
