Answer:
2.6+3.1+5.4 =21.1
if you have 20
subtract 21.1-20
then you have 1.1
since the difference is 1.1 then we say
21.1>20
Determine whether the equation 6d+8=14+3d One solution, no solution, or infinitely many solutions
Answer:
One solution
Answer, d = 2
Step-by-step explanation:

According to the table, the given stack of numerals correspond to
15
7
19
13
11
0
(A shortcut for reading these numbers: each bar represents 5 and each dot represents 1. The disk just means 0. So for instance, 13 = 5 + 5 + 3 = 2 bars + 3 dots.)
Mayan numerals are expressed in base 20, so the number above is equivalent to
15×20⁵ + 7×20⁴ + 19×20³ + 13×20² + 11×20¹ + 0×20⁰
= 49,277,420

Which of the following graphs presents a function?
Step-by-step explanation:
Verify a function using the vertical line testVerify a one-to-one function with the horizontal line testIdentify the graphs of the toolkit functionsone quarter of a certain number added to one eighth of the same number is 12. What is the number
Answer:
32
Step-by-step explanation:
let the number be n , then
[tex]\frac{1}{4}[/tex] n + [tex]\frac{1}{8}[/tex] n = 12 ( multiply through by 8 to clear the fractions )
2n + n = 96
3n = 96 ( divide both sides by 3 )
n = 32
The number is 32
The radius of the sphere is 6 millimeters. Which equation can be used to find the surface area of the sphere? A sphere with a radius of 6 millimeters. S = 4 pi r squared = 4 (6) squared S = 4 pi r squared = 4 pi (12) squared S = 4 pi r squared = 4 pi (6) squared + 2 pi (6) S = 4 pi r squared = 4 pi (6) squared
9514 1404 393
Answer:
(d) S = 4 pi r^2 = 4 pi (6)^2
Step-by-step explanation:
The formula for the area of a sphere is ...
A = 4πr^2
Filling in the given radius value, we get ...
A = 4π·6^2

Mrs. Schellhaas spent $14.00 of the $20.00 she has on her Starbucks gift card. Which decimal represents the fraction of the $20.00 she spent
Answer:
0.7 or 70%
Step-by-step explanation:
Step 1 : Find what percent 14 is of 20. Set up an equation to solve for x.
14 = x (20)
Divide by 20 on both sides.
14 divided by 20 = 0.7
So the decimal which represents the fraction of the 20 bucks she spent is 0.7
Bonus step : If you want to find what is 0.7 in percentage form, then simply convert. 70/100 = 70 percent.

Measure of angle YXZ = 49.75 degrees
Step-by-step explanation:
Complementary angles have a sum of 90 degrees so we add them and set them equal to 90.
3x + 2 + 5x - 14 = 90
Combine like terms
8x - 12 = 90
Add 12 to both sides
8x = 102
Divide both sides by 8 to isolate x
x = 12.75
Measure of angle YXZ = 49.75 degrees

Determine if the conjecture is true or false. If true, explain your reasoning briefly. If false provide a counterexample.
A. Given that 1/5[tex]\leq[/tex]5,
1/20[tex]\leq[/tex], 20,
and 1/38[tex]\leq[/tex]38, you conjecture that 1/x[tex]\leq[/tex]x all real numbers x[tex]\leq[/tex] 0
9514 1404 393
Answer:
false
Step-by-step explanation:
The conjecture shown in this problem statement does not follow from the examples offered. They support the notion that ...
1/x ≤ x . . . . for x ≥ 0 (not x ≤ 0)
There are several possible counterexamples showing the conjecture is FALSE.
1/0 is undefined1/(-5) > -5 . . . . . . . . a case for x < 0If the intended domain is x ≥ 0, then the conjecture can also be demonstrated to be false for 0 < x < 1:
1/(1/5) > 1/5Simplify the following expression:

3x2 − 12x + y
3x2 − 12x − 13y
Answer:

x-2x=-66-34
-x = -100
x = 100
m L DBC = x-33 = 100-33 = 67°
