Answer:
the answer is x = 75
Step-by-step explanation:
the base angles of an isoscles triangle are equal, so I guess the answer is 75.
( and this is an isoscles triangle as the two sides are equal.)

Y (x)=5900 (1.04)^x
Y (12)=5900×(1.04)^(12)= 9446.09008954

Ms. Frank purchased notebooks for $12.57 before tax. If the sales tax on her purchase was 6%, how much money should Ms. Frank have to pay for the notebooks in total.
Answer:
$13.32
Step-by-step explanation:
To find the tax, convert the percentage to decimal form and get 0.06. Multiply 0.06 by 12.57 to get 0.7542. Add this to 12.57 to get 13.3242. When rounded to the nearest hundredths place this becomes $13.32
Look at each equation. Does the equation represent a line with slope m = 5, containing the point (3, 8)? Select Yes or No for each equation.
5x − y = 7
Answer:
Yes it does.
Step-by-step explanation:
If you put this in point-slope-form you can substitute the ordered pair into the equation then solve.
through (2, -4) and parallel to y= 9/2x+3
Answer:
y=[tex]\frac{9}{2\\}[/tex] x-13
Step-by-step explanation:
first, since it's parallel the slope has to be the same and the y-intercept has to be different.
you will have y=9/2x+b
find b, by using the points you are given so you will get
-4=(9/2) times (2)+b.
then when sloving you will get b=-13 and so the full equation will be
y=9/2x-13

work out the area of this semi circle
Answer:
39.27
Step-by-step explanation:
The area of a semi-circle is pi times the radius squared divided by 2. So basically standard area of a circle formula (pi times the radius squared) but then you add in the extra step of dividing it by 2.
The formula looks like this:
π × r² ÷ 2
The radius is half the diameter of the circle. So basically think of it as a line to the middle of the circle. Our diameter is 10, (the diameter is the entire length of the circle. It gives us this already. If you need diameter and only have the radius add the radius together twice or multiply it by 2 to get the diameter. Fun fact..?)
and it tells us to substitute pi for 3.142.
So, plugging our numbers in we get:
3.142 x 5^2 ÷ 2 = 39.275.
Cut out the 3rd decimal place (5) as it tells us to only include the first 2 decimal places, and we finally end up with 39.27.
Hope this helps and have a nice day!
LA Fitness charges a registration fee of $75 plus $35.75 per month for members. Gold's Gym charges a registration fee of $164 plus $17.95 for members. After how many months would the total cost at LA Fitness and Gold's Gym to be the same for members? The cost will never be the same. The cost will never be the same. 5 months 5 months 7 months 7 months 10 months \
Answer:
After 5 months
Step-by-step explanation:
Step one:
given data
LA Fitness charges a registration fee of $75 plus $35.75 per month for members
let the number of months be x
and the total charges be y
total is
y= 75+35.75x----------1
Gold's Gym charges a registration fee of $164 plus $17.95 for members
let the number of months be x
and the total charges be y
total is
y= 164+17.95x----------2
Step two:
equate 1 and 2
75+35.75x= 164+17.95x
solve for x
35.75x-17.95x=164-75
17.8x=89
divide both sides by 17.8
x=89/17.8
x=5 months

xD im a bit late :P
we can pick any 2 points on the line.
let's pick, (-1, 2) and (-3, 1)
Alright, so the formula to calculate slope is in the attachment below.
If you're a bit confused on what the little 2 and 1 at the bottom of each of those numbers are representing the points. So let's say (-3, 1) is point 2. And (-1, 2) is point 1.
the variable "y" is the y-coordinate.
the variable "x" is the x-coordinate.
And all we need to do now is just sub in the values and that's your answer.
so we have the 2 y-coordinates, 1 and 2.
We subtract them. 1-2=-1
then we have the 2 x-coordinates, -1, -3
-1-3=-4
so -1/-4 is -0.25

Allie fires a rocket from ground level. The height of the rocket is given by the formula h= 260t - 16t^2 (-16t squared), where t is the time in seconds after launch. How long will the rocket be in the air?
Answer:
The rocket would be in the air for 8.125 seconds after launch.
Step-by-step explanation:
Given that the height of the rocket, h = 260t - 16[tex]t^{2}[/tex].
To determine how long the rocket would be in the air, differentiate h totally with respect to t.
So that, total derivative of h is given as;
[tex]\frac{dh}{dt}[/tex] = [tex]\frac{d(260t-16t^{2}) }{dt}[/tex]
0 = 260 - 16 x 2t
= 260 - 32t
0 = 260 - 32t
32t = 260
t = [tex]\frac{260}{32}[/tex]
= 8.125
t= 8.125 seconds
The rocket would be in the air for 8.125 seconds after launch.

Ramiro se dedica a circular terrenos se le presenta un trabajo se circular un terreno cuadrado con una superficie de 470 metro cuadrados y le piden que lo circulen con 4 hilos de alambre de puas sobre postes. ¿cuantos metros lineales con alambre de puas nesecita?
Answer:
346.88 meters
Step-by-step explanation:
Given that the area of the square-shaped terrain is 470 square meters.
Let a be the side of the terrain, so
Area of the square-shaped terrain, [tex]a^2=470[/tex] square meters.
Therefore, the length of one side, [tex]a=\sqrt {470}=21.68[/tex] meters.
The length of single thread wire required in circulating the square-shaped terrain = the perimeter of the square-shaped terrain
As the perimeter of a square having side a = 4a
So, the length of single thread wire required in circulating the square-shaped terrain= 4 x 21.68 =86.72 meters
Therefore, the length of 4 thread wire required in circulating the square-shaped terrain= 4 x 86.72=346.88 meters.
Point B is halfway between A and C. The distance from C to D is the same as the distance from D to E, which is the same as the distance from E to F. The area of triangle ACF is 180 cm2. How many square centimeters is the shaded area of triangle BCE?
Answer:
3
Step-by-step explanation:
3
ΔBCE is half the base length and two third the height of ΔACF, therefore,
the area of ΔBCE is less than half the area of ΔACF.
The area of triangle ΔBCE is 60 cm².
Reasons:
In ΔACF, we have;
B = The midpoint of AC
Point E and point D are points on side CF
Distance C to D = Distance D to E = Distance E to F
Area of ΔACT = 180 cm²
Required:
Area of ΔBCE
Solution:
[tex]Area \ of \, \Delta ACF = \mathbf{\dfrac{1}{2} \times AC \times CF} = 180 \ cm^2[/tex]
[tex]In \ \Delta BCE, \, BC = \dfrac{1}{2} \times AC \ and \ CE = \dfrac{2}{3} \times CF[/tex]
Therefore;
[tex]Area \ of \ \Delta BCE = \dfrac{1}{2} \times BC \times CE = \dfrac{1}{2} \times \left(\dfrac{1}{2} \times AC \ \right) \times \dfrac{2}{3} \times CF[/tex]
[tex]\dfrac{1}{2} \times \left(\dfrac{1}{2} \times AC \ \right) \times \dfrac{2}{3} \times CF = \dfrac{1}{2} \times \dfrac{2}{3} \times \left(\dfrac{1}{2} \times AC \ \right)\times CF = \mathbf{\dfrac{1}{3} \times Area \ \Delta ACF}[/tex]
Therefore;
[tex]Area \ of \ \Delta BCE = \dfrac{1}{3} \times Area \ \Delta ACF = \dfrac{1}{3} \times 180 = 60[/tex]
The area of triangle ΔBCE = 60 cm².
