The percentage of the calls were greater than 30 minutes in duration is 69%.
How to illustrate rye information?Let N = 77 Total long-distance calls
X= 24 calls are less than or equal to 30 minutes duration
Y = N - X= 77 - 24= 53 calls are greater than 30 minutes duration
To find the percentage of calls greater than 30 minutes duration. This goes thus:
= Number of calls greater than 30 minutes / Total calls
= 53 / 77
= 0.69
Therefore, 69% of the call were greater than 30 minutes in duration.

Beau lifts weights at his local gym on a regular basis. When he started working out, he weighed 127 pounds. Beau kept track of his weight and found that he gained 2 pounds every month. If Beau’s goal is to weigh at least 155 pounds after working out for m months in a row, which inequality best represents this situation?
Answer: it would take 19 months to get to 155
Step-by-step explanation:
If Beau weighed two more each month and wanted to get to 155 then you count by two's and see that it would take 19 months to weight 155

A function f is given, and the indicated transformations are applied to its graph (in the given order). Write the equation for the final transformed graph.
f(x) = x^2; shift 6 units to the left and reflect in the x-axis
Answer:
[tex]y=-(x+6)^2[/tex]
Step-by-step explanation:
Shifting 6 units left, we get:
[tex]x^2 \longrightarrow (x+6)^2[/tex]
Reflecting over the y-axis. we get:
[tex](x+6)^2 \longrightarrow -(x+6)^2[/tex]
So, the final equation is
[tex]y=-(x+6)^2[/tex]

The domain and range of of the graph in interval notation are [-4,3) and (-5,5).
Domain and range of a graph.The domain are the independent variables for which an expression or equation exists while the range are the dependent variables for which an expression or equation exists.
The given graph is a piecewise function since there are several lines that make up the graph.
Te domain are values of the function lying along the x-axis of the line graph while the range are values of the function along the y-axis of the line graph.
Based on the explanation, we can conclude that the domain of the graph in interval notation will be [-4,3) and the range of the graph will be (-5,5).

AB : BC = 3:2
Point B ∈ AC . Find the lengths of segments AB and BC if AC = 20 cm
The length of the segments AB and BC if AC = 20 then:
AB = 12cm
BC = 8cm
What is the simplest definition of a line segment?In geometry, a line segment is defined as two different points on a line. In contrast, a line segment is a piece of a line that connects two points. A line has no endpoints and runs indefinitely in both directions, whereas a line segment has two fixed as well as definite endpoints.
Is there a distinction between a line segment as well as a ray?Yes. A ray is not the same as a line segment. A ray has one endpoint, but a line segment has two. The ray's one end extends indefinitely, whereas the endpoints of a line segment are always specified and fixed.
According to the given data:We know that:
a:b=c:d as a/b=c/d
AB:BC = 3:2
is AB/BC=3/2
AB=3/2*BC
AC=20=AB+BC
So,
20=3/2*BC+BC

find the number of stamps measured 3cm × 4cm needed to fill the square card with a side of 12cm
Answer:
Breadth of stamp=3 cm
Length of stamp=4 cm
Area of stamp = Area of rectangle = l*b = 3*4 = 12 cm^2
Side of square card = 12 cm
Area of card = Area of square = side^2 = 12^2 = 144 cm^2
No. of stamps that can be filled in card
= Area of card / Area of stamp
= 144/12
= 12
:. 12 stamps can be filled in a card of side 12 cm.

What is the inverse of this function?

x²-
-
for x ≤
Answer:
4, 3, 0
Step-by-step explanation:
Let f(y)=x.
[tex]x=-\frac{1}{2}\sqrt{y+3} \\ \\ -2x=\sqrt{y+3} \\ \\ 4x^2=y+3 \\ \\ y=f^{-1}(x)=\boxed{4}x^2-\boxed{3}[/tex]
The domain of the inverse is the same as the range of the original function. For the original function, we know that it is decreasing, so the range is
[tex]y\leq -\frac{1}{2}\sqrt{-3+3}=0[/tex]
and hence the domain of our inverse is
[tex]x \leq 0[/tex]
Suppose that E and F are points on the number line.
If EF=15 and E lies at 4, where could F be located?
If there are several locations, separate them with commas.
When E = 4 on the number line, then F can either be 11 or be 19 to make EF as 15 units.
We are given that:
E and f are the points on a number line.
We are also given that the distance between E and F is:
EF = 15 units
Now, we know that E lies at 4
E = 4
We need to find the location of the point F
Now, since we also know that:
EF = F ± E
Substituting the values:
15 = F ± 4
We get that:
15 = F + 4 or 15 = F - 4
F = 15 - 4 or F = 15 + 4
F = 11 or F = 19
Therefore, we get that, when E = 4 on the number line, then F can either be 11 or be 19 to make EF as 15 units.

11h-5(h+3)=-63 find they value of h
Answer:
h = -13
Step-by-step explanation:
Use PEMDAS to solve this problem.
11h - 5(h + 3) = -63
~Use distributive property to simplify [ a(b + c) = ab + ac ]
11h - 5h + 15 = -63
~Combine like terms
6h + 15 = -63
~Subtract 15 to both sides
6h = -78
~Divide 6 to both sides
h = -13
Best of Luck!
Answer:
Step-by-step explanation:
11h - 5(h + 3) = -63
-Multiply parenthesis so
-5(h) + -5(3) = -5h - 15
New equation: 11h - 5h - 15= -63
+15 +15
(add 15 to both sides)
[tex]6h=-48\\\\\frac{6h}{6} =\frac{-48}{6} \\ \\ h=-8[/tex]

A two-liter bottle contains 53.1 centiliters of oil and 7.9 deciliters of water. How much more liquid is needed to fill the bottle?
Answer: 0.679 liters
Step-by-step explanation:
A centiliter is a measure of volume equal to one hundredth of a liter
Hence,
53,1*0.01=
0.531 liters
A deciliter is a measure of volume equal to one tenth of a liter
Hence,

A computer programmer receives a weekly wage of $1350, and &229.50 is deducted for income tax. Find the percent of the computer programmer’s salary deducted for income tax.
The percent of the computer programmer’s salary deducted for income tax is 17%.
What is percentage of a number?
A percentage is a ratio or number that can be expressed as a fraction of 100. In order to calculate a percentage of a number, we must divide it by 100 and then multiply the resulting number by 100. The proportion therefore denotes a component per 100. A percentage of one hundred is what is meant by the word "percent."
Given, weekly wage is $1350 and deduction amount for income tax is $229.50.
The percent of deduction is
[tex]\frac{229.50}{1350} \times 100\\=0.17 \times 100\\=17[/tex]
Therefore, the percent of the computer programmer’s salary deducted for income tax is 17%.
