Mrs. Claus wants to have a nice meal ready when Santa comes home. She wants to make waffles and she knows that he will be hungry. If each recipe requires ¾ cups of butter and she has 4 ½ cups of butter, how many waffle recipes can she make?
Answer:
6
Step-by-step explanation:
Each recipe of waffles requires 3/4 cups of butter
Mrs Claus has 4 1/2 cups of butter
Therefore the number of recipes which she will be able to make can be calculated as follows
= 4 1/2 ÷ 3/4
= 9/2 ÷ 3/4
= 9/2 × 4/3
= 6
Hence Mrs Claus can make 6 recipes

Write a linear function f with the values f(-1)=-3 and f(2)=6.
Answer:
y = 3x
Step-by-step explanation:
Equation of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
We are given the following values of the function: f(-1)=-3 and f(2)=6. The points are (-1,-3) and (2,6). The slope is:
[tex]\displaystyle m=\frac{6+3}{2+1}=\frac{9}{3}=3[/tex]
Now find the equation of the line using the second point:
y - 6 = 3 ( x - 2 )
Operating:
y - 6 = 3x - 6
Simplifying:
y = 3x

x + y + z = 7200
0.04x + 0.11y + 0.14z = 805
z = x + y + 200
Using the system of equations x+y+z=7200, 0.04x+0.11y+0.14z=805 and z=x+y+200, the value of x=1400,y=2100 and z=3700
Given,
The equations
x+y+z=7200
0.04x+0.11y+0.14z=805
z=x+y+200
Substitute the value of z in the first and second equations
x+y+x+y+200=7200
2x+2y+200=7200
2x+2y=7000
x+y=3500 (1)
Similarly
0.04x+0.11y+0.14(x+y+200)=805
0.04x+0.11y+0.14x+0.14y+28=805
0.18x+0.25y=777
Multiply the equation by 4
0.72x+y=3108 (2)
We have to use elimination method here
Subtract the equation (1) from (2)
x-0.72x=3500-3108
0.28x=392
x=1400
Then,
x+y=3500
1400+y=3500
y=2100
z= x+y+200
z=1400+2100+200
z=3700
Hence, using the system of equations x+y+z=7200, 0.04x+0.11y+0.14z=805 and z=x+y+200, the value of x=1400,y=2100 and z=3700

What expression is equivalent to
Answer:
A
Step-by-step explanation:
Okay.
A negative exponent means we want to "flip" the term.
so we get
(1/-c^2)^1/3
When we get a fraction exponent, we want to "root" the term by that
so we get
[tex]\sqrt[3]{\frac{1}{-c^2} }[/tex]
Which simplifies to
[tex]\frac{\sqrt[3]{1} }{\sqrt[3]{-c^2} }[/tex]
Which becomes[tex]1/\sqrt[3]{-c^2}[/tex]
If a = 3 sqrt(3) in the right triangle shown, what is the value of b?
Note: Consider the below figure attached with this question.
Given:
[tex]a=3\sqrt{3}[/tex]
To find:
The value of b.
Solution:
In a right angled triangle,
[tex]\tan \theta = \dfrac{Perpendicular}{Base}[/tex]
For the given right angled triangle,
[tex]\tan \theta = \dfrac{a}{b}[/tex]
[tex]\tan (30^\circ) = \dfrac{3\sqrt{3}}{b}[/tex]
[tex]\dfrac{1}{\sqrt{3}} = \dfrac{3\sqrt{3}}{b}[/tex]
On cross multiplication, we get
[tex]1\times b=3\sqrt{3}\times \sqrt{3}[/tex]
[tex]b=3(3)[/tex]
[tex]b=9[/tex]
Therefore, the value of b is 9.
The youth group at the church decided to plant geraniums and
daisies around the church grounds as a group project. Geraniums
in 6" pots cost $4 each and daisy plants cost $6 each. The youth
group spent $410 on 80 plants. How many geraniums and how many
daisy plants did the group buy?
Answer:
The youth group bought 35 geraniums and 45 daisy plants.
Step-by-step explanation:
We can solve this using a system of equations:
x + y = 80
4x + 6y = 410
X = Geraniums
Y = Daisies
First, let's solve for a variable in the first equation. I am going to solve for y in the first equation:
x + y = 80
y = -x + 80
Now that we have solved for y we can plug that back in to the 2nd equation:
4x + 6(-x + 80) = 410
4x - 6x + 480 = 410
-2x + 480 = 410
-2x = -70
x = 35
Now that we have found the amount of geraniums we can plug it back into the first equation and solve for y:
35 + y = 80
y = 45
Therefore the youth group bought 35 geraniums and 45 daisy plants.
Check:
(35) + (45) = 80
80 = 80
4(35) + 6(45) = 410
140 + 270 = 410
410 = 410

1. Pentagon MNPQR is shown on the coordinate grid. Pentagon MNPQR is dilated with
the origin as the center of dilation using the rule (x, y) - (x, y) to create pentagon
M'N'P'Q'R'. Which statement is true?
Answer:
B
Step-by-step explanation:
if its less than 1 it shrinks
The correct statement is; Pentagon M’N’P’Q’R is smaller than pentagon MNPQR because the scale factor is smaller than 1.
What is the scale factor?The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.
If a polygon is dilated by a scale factor = k
Rule to be followed as;
(x, y) → (kx, ky)
Here, k = Scale factor
If 0 < k < 1, size of the image will be reduced.
Similarly, k > 1, size of the image will be enlarged.
We are given that Pentagon MNPQR is dilated with the origin as the center of dilation to form an image M'N'P'Q'R'.
Rule used for the transformation,
(x, y) → (1/4x, 1/4y)
Here, the scale factor through which MNPQR has been dilated is 1/4.
Since, scale factor is between zero and 1/4, size of M'N'P'Q'R' will be reduced.
Therefore, the size of pentagon M'N'P'Q'R' will be 1/4 smaller than pentagon MNPQR.
Option (2) is the answer.

S varies inversely as G. If S is 8 when G is 3.5, find S when G is 7.
a) Write the variation.
b) Find S when G is 7.
Answer:
a) S varies inversely as G
[tex]S\propto\frac{1}{G}[/tex]
or [tex]S=\frac{K}{G}[/tex]
b) S=4 when G=7
Step-by-step explanation:
a) Write the variation.
S varies inversely as G
[tex]S\propto\frac{1}{G}[/tex]
So, We can write: [tex]S=\frac{K}{G}[/tex]
Where k is constant of proportionality
b) Find S when G is 7.
Now, if S=8, G = 3.5 we will find K
[tex]S=\frac{K}{G}\\K=SG\\K=8\times 3.5\\K=28[/tex]
So, value of K= 28
Now, find S when G is 7
[tex]S=\frac{K}{G}\\S=\frac{28}{7}\\S=4[/tex]
So, S=4 when G=7

Morgan throws a ball up into the air. The height of the ball above the ground, in feet, is modeled by the function h(t) = −16t 2 + 24t, where t represents the time, in seconds, since the ball was thrown. What is the appropriate domain for this situation?
Answer:
I will give you the link below to a PDF that one of my young friends made for someone who had this exact question.
Step-by-step explanation:
The appropriate domain for this situation is [tex]\{t : 0 \leq t \leq 1.5\ \& \: t \in \mathbb R \}[/tex] (that means t can be any real number and between 0 and 1.5 (both endpoints included)
What is domain and range of a function?Domain is the set of values for which the given function is defined.
Range is the set of all values which the given function can output.
For this case, we have only those values of 't' as appropriate value, which are from t = 0 till the time when ball hits the ground, since after that the height will be constantly 0, but the height function will give negative values which doesn't model the situation correctly.
Thus, those values of t for which the equation [tex]h(t) = -16t^2 + 24t[/tex] correctly models the real world situation are said to be appropriate values of domain of this function.
The time when the ball will reach the ground will be when the height will be 0, thus,:
[tex]0 = -16t^2 + 24t\\2t^2 - 3t = 0\\(2t-3)(t) = 0\\t = 0, t = 3/2 = 1.5 \: \rm sec[/tex]
The height is 0 when ball starts going up(t=0), and when t = 1.5 the ball reaches ground.
Thus, the appropriate domain for modelling the situation is values of t in the interval [0, 1.5] (both endpoints are inclusive, as shown by big bracket).

Patrick leaned a 30-foot ladder against the side of a building. The
base of the ladder is 17 feet from the base of the building. The top of
the ladder is 11 feet from the top of the building. How tall is the
building? Provide an answer accurate to the nearest tenth of a foot.
The distance between the bottom of the ladder and the ground's surface is 24.7 feet.
Given that a is the ground, b is the building, and c is the ladder.
Also the ground is perpendicular to the building, the ladder, the building, and the ground form a right triangle.
Therefore, the Pythagorean theorem can be applied as follows:
c² = a² + b²
According to the information in the problem, c is 30 feet, b is 17 feet, and we solve for a as follows:
(30 ft)² = a² + (17 ft)²
900 ft² = a² ₊ 289 ft²
900 ft² ₋ 289 ft² = a²
611 ft² = a²
a² = 611 ft²
a = √611 ft²
a = 24.71
rounding off to nearest tenth, so a = 24.7
Hence the bottom of the ladder is 24.7 feet far away from the base of the ground.
