1) You are eating 3/4 cup of ice cream, 1/8 cup of chocolate syrup, and one sixteenths cup of cherries. How many (total) cups is your dessert?
Answer:
3/4=ice cream
1/8=chocolate syrup
1/16=cherries
Total=3/4+1/8+1/16
[tex]\frac{3X4}{4X4} +\frac{1X2}{8X2} + \frac{1X1}{16X1} \\\frac{12+2+1}{16} = \frac{15}{6}[/tex]
Total cups =15/6=2.5 cups.

find the area of the figure below
A.288.62
B.266.22
C.186.66
D.236.6
Answer:
A. 288.62
Step-by-step explanation:
Area of two triangles = 15.3 * 10.4 = 159.12
Area rectangle = hypotenuse triangle * 7
hypotenuse = √108.16 + 234.09
Hypotenuse = 18.5
Area rectangle = 18.5 * 7 = 129.5
129.5 + 159.12 = 288.62
Answer = A. 288.62

Answer: 20 ft
Step-by-step explanation:
The mirror is set away from the flagpole on the same scale set away from her.
The distance she stand's away from the mirror is 1/4 of the length of the distance between the mirror and the flag pole because she's 1/4 of the flagpole's size.
This means her size x4 is the size for the flag pole. This checks out because 12x4=48
So to find the height we must do 5x4

he constant 250 in the expression represent?
Answer:
The input for the method is a continuous function f, an interval [a, b], and the function values f(a) and f(b). The function values are of opposite sign (there is at least one zero crossing within the interval). Each iteration performs these steps: Calculate c, the midpoint of the interval, c = a + b2.

Rita is spending more time at home to study and practice math. Her efforts are finally paying off. On her first assessment she scored 58 points, then she scores 63 and 68 on her next two assessments. If her scores continued to increase at the same rate, on which assessments will she be scoring above 85? Select all that apply.
Answer:
7th
Step-by-step explanation:
63 - 58 = 5
68-63 = 5
She is adding 5 points each time
a1 = 58
d = 5
a2 = 63
a3 = 68
a4 = 58+5 = 73
a5 = 73+5 = 78
a6 = 78+5 = 83
a7 = 83+5 = 88
This is the first assessment greater then 85, so the 7th assessment

Se tienen 25 billetes de 5 y de 20 lempiras con un monto de 350 lempiras cuantos billetes de 5 lempiras se tienen y de 20 lempiras
Answer:
El número de facturas
5 lempiras = 10 billetes
20 lempiras = 15 billetes
Step-by-step explanation:
Vamos a representar
El número de facturas de
5 lempiras = x
20 lempiras = y
Nuestro sistema de ecuaciones se da como:
x + y = 25 ..... Ecuación 1
x = 25 - y
5 × x + 20 × y = 350
5x + 20y = 350 .... Ecuación 2
Sustituiríamos x por 25 - y en la ecuación 2
5 (25 - años) + 20y = 350
125 - 5 años + 20 años = 350
125 + 15 años = 350
15 años = 350 - 125
15 años = 225
y = 225/15
y = 15
Resolviendo para x
x = 25 - y
x = 25 - 15
x = 10
Por lo tanto, el número de facturas
5 lempiras = 10 billetes
20 lempiras = 15 billetes
Raul is flying a kite at the end of a string that is 200 feet long. Raul is holding the string 5 feet off the ground at the angle to the horizontal of 25. How high is the kite off the ground?
Answer:
Kite is 89.52 ft off the ground
Step-by-step explanation:
We are told that the string is 200 ft long.
That the string is 5 ft off the ground at an angle of 25° to the horizontal.
I have drawn a triangle to depict this illustration with x being the height of the kite from the end of the string.
Also, I have depicted the ground level which is 5 ft below the end of the string.
From the triangle, we can calculate the height of the kite above the end of the string using pythagoras theorem.
x/200 = sin 25
x = 200 sin 25
x = 200 × 0.4226
x = 84.52 ft
Now, the bottom of the kite is 5 ft off the ground as depicted in the attachment.
Thus, height of kite above the ground = 84.52 + 5 = 89.52 ft

y<3x+2
y>3x+2
y<1/3x+2
y>1/3x+2
Answer:
Y < 3x+2
Step-by-step explanation:
Alright so if you ever get stuck on something like this, Go on demos and put in (0,2) and then add in (-3,-7) and then add in the other answers to see if they match.
So your answer is:
y>3x+2
PLEASE HELP! SEE PHOTO FOR QUESTION
Answer:
A
Step-by-step explanation:
Intercepts are basically points where if one of the coordinates is a number above 0, the other one HAS TO BE 0
Since there are three points where there are x-intercepts (since the y is 0), there will be three x-intercepts.
Since there is only one point where there are y-intercepts (since the x is 0), there will be only one y-intercept.
The intercepts don't give an exact answer so you would have to estimate where they are on the graph. For example, the y-intercept is between 20-30 and is leaning more towards 30, so you would think it's around 27-29 (And if you look at option A, you can see that it's (0,28))
You got the answer wrong because for one of the x-intercepts, you said that it was negative when it was actually positive. (I believe it was the (2.3,0) one.)

I have this math problem and it is: an equation in function from that reflects f(x)=3x over the line y=0.
Answer:
[tex]g(x) = -3x[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x[/tex]
Required
Reflect over [tex]y = 0[/tex]
This means that we reflect over the x-axis
And the rule of reflection is:
[tex](x,y) \to (x,-y)[/tex]
Hence:
[tex]f(x) = 3x[/tex]
Will become:
[tex]g(x) = -f(x)[/tex]
So, we have:
[tex]g(x) = -3x[/tex]

Chin was shown the graph of a line that contained point (1, 7). He wrote f(x) = 4x + 3 to correctly represent the line. Which of these equations could represent the same line?
y – 7 = 3(x – 1)
y – 1 = 3(x – 7)
y – 7 = 4(x – 1)
y – 1 = 4(x – 7)
The equation that represents the same line containing point (1, 7) is as follows:
y - 7 = 4(x - 1)
Slope intercept form equation:y - y₁ = m(x - x₁)where
m = slope
The graph of the line contains (1, 7) .He represent the line correctly as f(x) = 4x + 3.
The equation that represent the same line is as follows:
Using the model:
y = mx + b
Therefore,
m = 4
Finally , the equation is as follows:
