Answer:
24 x61=74.000Step-by-step explanation:
if you take it by the first number then you will divide the firsts to the nearest number that applies the first number
The convert rate is $1 = 6.35 yuan.
-> $24000 = 6.35 x 24000 = 152400 yuan (152481.60)

Answer:
Surface Area = [tex]530yd^2[/tex]
Step-by-step explanation:
*This answer is for the problem on the left that seems unanswered*
Firstly, you must understand that the surface area of an irregular polygon like the one in the problem must be found by dividing its faces into rectangles and finding the sum of the areas of those rectangles.
Another way to say this is that the surface areas of these solids can be found by adding up the areas of the rectangles that make their faces.
You will see that I attached a picture that divides the solid's faces into subsections, labelled a through i, including faces that are not visible in the diagram.
If you divided the solid's faces in the same way as the picture, the surface area is found as follows:
[tex]Area_A=12*7=84yd^2\\Area_B=12*4=48yd^2\\Area_C=12*4=48yd^2\\Area_D=4*4=16yd^2\\Area_E=11*3=33yd^2\\Area_F=12*3=36yd^2\\Area_G(notVisible)=12*11=132yd^2\\Area_H(notVisible)=12*7=84yd^2\\Area_I(notVisible)=Area_E+Area_D=33+16=49yd^2[/tex]
By the way, [tex]yd^{2}[/tex] is the same as "square yards".
After finding the areas of each rectangle, add them all up to get your final answer:
[tex]SurfaceArea=530yd^2[/tex]

PLEASE HELP ME ASAP !! Manny has $12,000 and is
saving for a used car that
costs $15,000. He is able to
save $300.00 per month
toward his car. Write and
solve an inequality for this
situation if m represents the
number of months that
Manny must save to buy the car.
Answer:
12,000+300m >= 15,000
300m >= 3,000
m>= 10
Step-by-step explanation:
This is basically the inequality that represents the problem and is solved algebratically.
Answer:
Inequality: 12,000 + 300m > 15,000
m = 10
It will take Manny 10 months to get the money for his car.
Step-by-step explanation:
The inequality is 12,000 + 300m > 15,000 ($12,000 + 300 dollars per month > $15,000)
Here is an image of how to solve the inequality:
A movie theater offers a reward program that charges a yearly membership fee and a discounted rate per movie ticket. The total cost for a reward program member to see 5 movies is $40 and the total cost for 12 movies is $75. Assume the relationship is linear. Write the equation of the function in the form y=mx+b , where x represents the number of movies and y represents the total cost.
Hint: Treat this information like ordered pairs. (5, 40) and (12, 75)
Answer:
[tex]y=5x+15[/tex]
Step-by-step explanation:
Since this situation is a linear relationship between the number of movies and the total cost, we need to determine the slope of the line given our two ordered pairs [tex](x_1,y_1)\rightarrow(5,40)[/tex] and [tex](x_2,y_2)\rightarrow(12,75)[/tex]:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{75-40}{12-5}\\ \\m=\frac{35}{7}\\ \\m=5[/tex]
Thus, our equation so far is [tex]y=5x+b[/tex]. Next, we need to find our y-intercept, [tex]b[/tex], which represents our flat fee. We do so by using one of our original given ordered pairs:
[tex]y=5x+b\\\\40=5(5)+b\\\\40=25+b\\\\15=b[/tex]
Therefore, our final equation for the function is [tex]y=5x+15[/tex]
AlgebraSHOW ALL WORKGiven the points (6,-4) and (0,4), find the slope, the y-intercept, and the x-intercept of the line that passes through both point. Also, GRAPH this line
Answer:
slope: -4/3y-intercept: (0, 4)x-intercept: (3, 0)y = -4/3x +4Step-by-step explanation:
Given two points, the equation for the line through them can be found using the slope formula and the slope-intercept form.
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-4))/(0 -6) = 8/-6 = -4/3 . . . . slope of the line
The y-intercept is 4, given by the second point.
The slope-intercept equation for a line is ...
y = mx +b . . . . . . line with slope m and y-intercept b
y = -4/3x +4 . . . . . line with slope -4/3 and y-intercept 4
__
The x-intercept can be found by solving for x when y=0.
0 = -4/3x +4
0 = 4x -12 . . . . multiply by -3
0 = x -3 . . . . . . divide by 4
3 = x . . . . . . . . subtract 3
The x-intercept is (3, 0).
__
The line can be graphed by plotting the given points and drawing the line through them.
Answer:
Slope: [tex]-\frac{4}{3}[/tex]
Y int. : (0,4)
X int. : (3,0)
Step-by-step explanation:
Equations to remember:
[tex]y = mx + b\\\\\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
--------------------------------------------
[tex](x_{1}, y_{1}) = (6, -4)\\\\(x_{2}, y_{2}) = (0,4)[/tex]
--------------------------------------------
SLOPE
You want to set up your equation for finding slope like this:
[tex]\frac{4 - (-4)}{0 - 6}[/tex]
4 - (-4) will become 4 + 4. This is because there is a -1 in front of the parenthesis.
A negative number times a negative number will always equal a positive number.
[tex]-\frac{8}{6}[/tex]
when simplified/divided by 2, which is the number you want:
[tex]-\frac{4}{3}[/tex]
This is your slope or your m in y = mx + b
---------------------------------------------------------------
Y INTERCEPT
Use one of your points.
I'll use (0,4) as an example.
Set up your equation like this:
[tex]4 = -\frac{4}{3}(0) + b[/tex]
Since your slope is being multiplied by ZERO, you can just eliminate your mx or slope.
This means that 4 = b!
That's your Y Int, which you'll find was one of the given points, (0,4).
---------------------------------------------------------------
From there, if you use a graph, you should find that your X Int is (3,0).

65. Find h if 3(2h-1) = 27(-h+2) A) 7 G D) 0
Answer:
A) 7/5
Step-by-step explanation:
An exponential equation like this can be solved by using logarithms, or by rewriting the bases so they are the same.
3^(2h-1) = 27^(-h+2)
Using 27 = 3^3, we can write the equation in terms of powers of 3:
3^(2h-1) = (3^3)^(-h+2)
3^(2h -1) = 3^(-3h +6)
Equating exponents gives ...
2h -1 = -3h +6
5h = 7 . . . . . . . . . add 1+3h
h = 7/5 . . . . . . . divide by 5
__
Additional comment
When solving this using a graphing calculator, it is often convenient to write the equation in such a way that the solution is an x-intercept. Here, we can do that by subtracting the right-side expression from both sides:
3^(2h-1) -27^(-h+2) = 0
The solution is h = 1.4 = 7/5.
Answer:
step by step explanation:h=7/5

A parallel line has a y-intercept of 12.
Write down the equation of this line.
Answer:
Using the equation form y = MX + b where a is the slope of the line and b is the y-intercept.
The line that is parallel this the line with equation 5x + y = 11 will have the SAME SLOPE as this line BUT the y-intercept will be -8 (as stated in the problem.)
Rewrite 5x + y = 11 to the standard form to yield the slope of that line.
So 5x + y = 11 becomes y = -5x + 11 where the slope is -5.
So the equation of the line that you want is then...y = -5x - 8. It satisfies both conditions.

If y varies inversely as x and y is 6 when x is 12, what is x when y is 14. 4? a. 5 b. 0. 4 c. 9. 6 d. 2. 5.
The value of x when y is 14.4 is 5.
It is given that
y ∝ 1/x
y = k/x....(1)
Where k is a constant of proportionality
What is the constant of proportionality?The constant of proportionality is the ratio that relates two given values.
When y =6, x=12
Means, 6 = k/12
k = 72
Putting the value of k in equation (1)
y = 72/ x
14.4 = 72/ x
x = 5
Therefore, The value of x when y is 14.4 is 5.

Find the measure of ∠WOV. Which angle relationship did you use?
Answer:
Measure of ∠WOV = 60°
Complementary angles
Step-by-step explanation:
The box shows us that is equal to 90°. Angles ∠WOV and ∠WOX are complementary angles because we get 90° when we add them together. Since we are given the measure of ∠WOX we can subtract it from 90° to find the measure of ∠WOV.
90° - 30 ° = 60°

Answer:
£3.15 (nearest pence)
Step-by-step explanation:
If the price of a coffee has increased by 7% then the final price of the coffee is: 100% + 7% = 107% of the original price.
Therefore, to find the original price of the coffee:
original price ÷ 107 × 100
= 3.37 ÷ 107 × 100
