Step-by-step explanation:
$15 - $6 = $9
Solve the inequality 5x-6<=2+(3x-4)
Answer:
x =< 2
Step-by-step explanation:
5x - 6 =< 2 + (3x - 4)
5x - 6 =< 2 + 3x - 4
5x - 3x =< 2 - 4 + 6
2x =< 4
x =< 2
To celebrate the first day of school, Reagan brought in a tray of caramel brownies and walnut brownies. The tray had a total of 20 brownies, of which 10% were caramel. How many caramel brownies did Reagan bring?
Answer:
18 I think
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
Reagan brought 2 caramel brownies.
Solve using a proportion.
[tex]\frac{?}{20}[/tex]=[tex]\frac{10}{100}[/tex]
You're trying to find how many brownies he brought were caramel. We know Reagan brought a total of 20 brownies. Therefore since you don't know how many caramel brownies he brought, the fraction would be ?/20. Next, you know he brought brownies in which 10% were caramel. In proportions, the denominator would be 100% since that is the total percentage. Therefore, the proportion would be 10%/100%. Now we just have to cross multiply.
Proportion:
[tex]\frac{?}{20}[/tex]=[tex]\frac{10}{100}[/tex]
10 x 20 = 200
200/100= 2
Thus, Reagan brought 2 caramel brownies.
Which equation in standard form has a graph that passes through the point (5, −2) and has a slope of 72 ?
A. 7x − 2y = 35
A. 7x − 2y = 35
B. 7x − 2y = 39
B. 7x − 2y = 39
C. 7x − 2y = −31
C. 7x − 2y = −31
D. 7x − 2y = −24
D. 7x − 2y = −24
Given:
Consider the graph passes through the point (5, −2) and has a slope of [tex]\dfrac{7}{2}[/tex].
To find:
The equation of graph in standard form.
Solution:
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope and [tex](x_1,y_1)[/tex] is the point lies on the line.
Slope is [tex]\dfrac{7}{2}[/tex] and graph passes through (5,-2), so the equation of line is
[tex]y-(-2)=\dfrac{7}{2}(x-5)[/tex]
[tex]y+2=\dfrac{7}{2}(x-5)[/tex]
Multiply both sides by 2.
[tex]2(y+2)=7(x-5)[/tex]
[tex]2y+4=7x-35[/tex]
[tex]4+35=7x-2y[/tex]
[tex]39=7x-2y[/tex]
The required equation is [tex]7x-2y=39[/tex].
Therefore, the correct option is B.
Calc how much interest you would earn on a deposit of $8500 at 2.75%,
compounded annually, for a term of 4 years?
9514 1404 393
Answer:
$974.28
Step-by-step explanation:
The formula for the account balance is ...
A = P(1 +r)^t
Subtracting the principal gives the amount of interest.
I = P((1 +r)^t -1)
i = $8500(1.0275^4 -1) ≈ $974.28
You would earn $974.28 in interest over that time period.
The slope of a line is 1, and the y-intercept is -1. What is the equation of the line written in slope-intercept form?
Answer:
y = x - 1
Step-by-step explanation:
Slope intercept form is y = mx + b
m is the slope and b is the y-intercept so it would be:
y = x -1 but u don't have to write 1x just x will do
Answer:
y = x - 1Step-by-step explanation:
slope intercept form
y = mx + bwhere m = 1
y-intercept = b = -1
therefore:
y = x - 1On neatly scaled axes, graph and then write an equation in terms of u and y for the distance Leslie travels. Let I represent time in seconds and y represent distance in meters. Then do the same for Kristin and Erie using the same set of axes.
Leslie: y= 2x
Kristin: y= 2/5x + 8
Erie: y= 5/4x + 6

Step-by-step explanation:
find the slope between the points (5,6) and (9,6)
Answer:
the slope is m=0
Step-by-step explanation:
when I put it in the graph and slope calculator I got 0
Answer:0
Step-by-step explanation:
The slope equation is y2-y1/x2-x1 so it would look like this: 6-6/5-9. If you simplify, the slope equals 0

One year, the population of a city was 130,000. Several years later it was 135,200.
Find the percent increase.
Answer:
Increase in percent = 4%
Step-by-step explanation:
Given:
Present population = 130,000
Future population = 135,200
Find:
Increase in percent
Computation:
Increase in population = Future population - Present population
Increase in population = 135,200 - 130,000
Increase in population = 5,200
Increase in percent = [Increase in population / Present population]100
Increase in percent = [5,200/130,000] 100
Increase in percent = 4%
One California fan palm tree grew 51 inches in 3 years. A queen palm tree grew 48 inches in 4 years. Which tree grew faster? Complete the explanation. The growth rate of the California fan palm is what inches per year and the queen palm's growth rate is what inches per year. So, the what grew faster.
Answer:
Queen palm tree grew faster than the California fan palm tree
Step-by-step explanation:
One California fan palm tree grows 51 inches in 3 years
Rate = 51/3 = 17 inches/year
A queen palm tree grows 48 inches in 4 years
Rate = 48/4 = 12inches/year
Clearly the Queen palm tree grew faster than the California fan palm tree as Queen palm tree grows 12inches/year than California Fan palm tree 17 inches/year .
Answer:
the california fan palm
Step-by-step explanation:
you have to know which tree grew faster so you have to know how many inches they grow per year so you have to...
divide 51 by 3 and the answer is 17 inches per year
and divide 48 by 4 and the answer is 12 inches per year
so 17 is greater than 12

A cook has a scoop that measures ¼ cup. A bread recipe calls for 1 ¼ cups of sugar and 2 ½ cups of flour. The cook uses the scoop to measure and put both ingredients into a bowl. How many total scoops of both ingredients does the cook put into the bowl?
Given:
A cook has a scoop that measures [tex]dfrac{1}{4}[/tex] cup.
Required sugar for bread recipe = [tex]1\dfrac{1}{4}[/tex] cups
Required flour for bread recipe = [tex]2\dfrac{1}{2}[/tex] cups
To find:
The total number of scoops of both ingredients does the cook put into the bowl.
Solution:
Required amount of sugar and flour for the bread recipe is
[tex]=1\dfrac{1}{4}+2\dfrac{1}{2}[/tex]
[tex]=\dfrac{1\times 4+1}{4}+\dfrac{2\times 2+1}{2}[/tex]
[tex]=\dfrac{4+1}{4}+\dfrac{4+1}{2}[/tex]
[tex]=\dfrac{5}{4}+\dfrac{5}{2}[/tex]
Taking LCM, we get
[tex]=\dfrac{5+10}{4}[/tex]
[tex]=\dfrac{15}{4}[/tex]
Now,
[tex]\text{Number of scoops}=\dfrac{\text{Total amount of sugar and flour}}{\dfrac{1}{4}}[/tex]
[tex]\text{Number of scoops}=\dfrac{\dfrac{15}{4}}{\dfrac{1}{4}}[/tex]
[tex]\text{Number of scoops}=\dfrac{15}{4}\times \dfrac{4}{1}[/tex]
[tex]\text{Number of scoops}=15[/tex]
Therefore, the required number of scoops is 15.

A runner's racecourse has a total distance of . Race officials want to mark the course every with a flag, including one at the finish line. (The starting line does not need a flag.) How many flags are needed? First fill in the blanks on the left side of the equation using three of the ratios shown. Then write your answer on the right side of the equation.
Complete question :
A runner's racecourse has a total distance of 2.5 mi. Race officials want to mark the course every 200 yd with a flag, including one at the finish line. (The starting line does not need a flag. How many flags are needed?
Answer:
22 flags
Step-by-step explanation:
Given that total distance = 2.5 miles
Marked distance = every 200 yards
Ratio of yard to miles:
1 mile = 1760 yards
Total distance in yards :
Note :
1 mile = 5280 feet
1 yard = 3 feet
Given that:
1 flag per 200 yards
Number of flags :
2.5 miles * (5280 / 1 ) * (1 /3) * (1 / 200) = 22 flags
Similarly ;
Since 1 mile = 1760 yards
Total distance in yards : (2.5 * 1760) = 4400 yards
Number of flags :
Total distance in yards / marked distance
= 4400 / 200
= 22 flags
Evaluate g(x)=6x when x=-3,0, and 4 .
Answer:
-3 = -18
0 = 0
4 = 24
Step-by-step explanation:
-3... so 6(-3) equals -18 because a positive times a negative equals a negative
0... so 6 (0) equals 0 because anything multiplied by 0 equals 0
4... so 6 (4) equals 24
() means multiplied by so if it’s y(x) then that means y is multiplied by x :)

The Population in Corpus Christi in 1970 was 204,525. The population in 2002 was 276,877. Create an
exponential equation and find out what the population will be in 2017?
When solving for b round it to the 4 decimals to use in the Equation. WHAT WILL BE THE POPULATION IN
2017?
Answer:
The population is 2017 is 291,254
Step-by-step explanation:
The exponential equation will be in the form
P = I( 1 + r)^t
where P is the present population
I is the population initially at 1970
r is the annual growth percentage
t is the number of years since 1970
So for 2002, we have
r in this case will be 2002-1970 = 32
277,877 = 204,525(1 + r)^32
(1 + r)^32 = 1.3586
1 + r = 1.0096
r = 1.0096-1
r = 0.0096
So the growth percentage is 0.96% annually
So the population in 2017 where t will be 2017-1970 = 37 will be
P = 204,525(1 + 0.0096)^37
P = 204,525(1.0096)^37
P = 291,254
