Each tweet would cost between 1 and 140 pennies you can write that as an inequality [1 ≤ x ≤ 140] Since you can't tweet 0 characters or above 140.
if you want to change it to pounds divide by 100.
A) 1 ≤ x ≤ 140
B) Each character costs a penny, you can't tweet less than 1 character or above 140.
Answer:
<h3>Add 47.6 and 39.75, then round the answer</h3>
Step-by-step explanation:
If Ramina found the length of two pieces of ribbon to be 47.6 inches and 39.75 inches, the effective strategy of finding the sum of the two lengths is to:
1) First is to add the two values together
47.6 + 39.75
= (47+0.6)+(39+0.75)
= (47+39)+(0.6+0.75)
= 86 + 1.35
= 87.35
2) Round up the answer to nearest whole number.
87.35 ≈ 87 (note that we couldn't round up to 88 because the values after the decimal point wasn't up to 5)
Option C is correct
He had 40 pencils left after he gave away 8, so originally he had 40 + 8 pencils, which is 48.
Now, he bought 4 packages, which had a total of 48 pencils, so divide 48 by 4, which is 12. He had 12 pencils in each package.
To determine the solution arithmetically, first add 8 to 40, then divide 48 by 4.
To determine the solution algebraically, set up and solve the equation 40 = 4x - 8.
Each package contained 12 pencils.
Hope this helps
Answer:
C. 905 in³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, sphere
We know that the volume of a sphere is expresses as
V= 4/3πr³
Given that the diameter of the sphere is 12inches
Radius r= 12/2= 6 inches
Substituting our radius we can solve for the volume
V=4/3(3.142*6³)
V= (4*3.142*216)/3
V= 2714.68/3
V= 904.9in³
Approximately V= 905in³
The equation would be 2x + 5y = 11.
To find this, we first have to find the slope of the line. The slope formula is below.
m (slope) = (y2 - y1)/(x2 - x1)
In which (x1, y1) is the first point and (x2, y2) is the second. So we plug in to solve.
m = (3 - 1)/(-2 -3)
m = 2/-5
Now that we have the slope, we can use it along with a point to get the slope intercept form.
y = mx + b
3 = -2/5(-2) + b
3 = 4/5 + b
11/5 = b
Now that we have the equation of y = -2/5x + 11/5 we can manipulate it into standard form.
y = -2/5x + 11/5 -----> add 2/5x to both sides
2/5x + y = 11/5 ----> multiply both sides by 5
2x + 5y = 11
