Miguel bought a ¾ pound bag of chocolate chips. He used ⅘ of the bag in his chocolate chip cookies. How many pounds of chocolate chips did he use?
Convert to percentages to understand the question better:
3/4 = 75%
4/5 = 80%
What is 80% of 75%?
Convert the percentages to decimals:
75% = 0.75
80% = 0.8
Calculate:
0.8 × 0.75 = 0.6
Convert back to original problem's format (fraction):
0.6 = 60% = 6/10 = 3/5
Miguel used 3/5 pounds of chocolate chips.

The line passing through (-3 , -6) and (d, -5d) has a gradient of -3.
Find the value of d.
Answer:
d = 7.5
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 3
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (d, - 5d)
m = [tex]\frac{-5d+6}{d+3}[/tex] = - 3 ( multiply both sides by (d + 3) )
- 5d + 6 = - 3(d + 3)
- 5d + 6 = - 3d - 9 ( add 3d to both sides )
- 2d + 6 = - 9 ( subtract 6 from both sides )
- 2d = - 15 ( divide both sides by - 2 )
d = 7.5

Find the midpoint of the line on the coordinate plane with the given endpoints below.
(-1, 1), (5, -5)
Answer:
Then the midpoint is (2, -2)
Step-by-step explanation:
We treat the x- and y-coordinates separately, first finding the average (mean) of the x-coordinates and then the average of the y-coordinates:
xm = (-1 + 5)/2 = 2
ym = (1 - 5)/2 = -2
Then the midpoint is (2, -2)
Answer:
(2,-2)
Step-by-step explanation:
Two points are given to us and we need to find the midpoint of those two points. The points are
(-1,1) and (5,-5) . Let us say we have two points ( x1,y1) and ( x2 , y2) . The midpoint will be ,
[tex]\implies Midpoint =\bigg( \dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2} \bigg) \\\\\implies Midpoint = \bigg( \dfrac{-1+5}{2},\dfrac{1-5}{2}\bigg)\\\\\implies Midpoint = \bigg( \dfrac{4}{2},\dfrac{-4}{2}\bigg)\\\\\implies \red{Midpoint = ( 2 , -2) }[/tex]

Clara has 9 pounds of apples. She needs 1 1/4 pounds to make one apple pie. If she saves 2 pounds for applesauce, how many pies, p, can she make? Write an algebraic equation to represent this situation.
Answer:
She can make :
5 3/5 pies
Algebraic equation =
1 1/4 p = (9 - 2)
Step-by-step explanation:
Clara has 9 pounds of apples. If she saves 2 pounds for applesauce, how many pies, p, can she make?
Total number of pounds of apples = 9 pounds
She saves 2 pounds for apple sauce
The number of pounds of apples left =
9 pounds - 2 pounds
= 7 pounds
She needs 1 1/4 pounds to make one apple pie.
Therefore
1 1/4 pounds = 1 apple pie
7 pounds = p
Cross Multiply
1 1/4 × p = 7 × 1
p = 7 ÷ 1 1/4
p = 7 ÷ 5/4
p = 7 × 4/5
p = 28/5
p = 5 3/5 pies
An Algebraic equation for this situation is:
1 1/4 p = (9 - 2)
Where p = Number of pies
A movie theater sells popcorn in bags of different sizes. The table shows the volume of popcorn and the price of the bag. If the theater wanted to offer a 60-ounce bag of popcorn, what would be a good price? Explain your reasoning
Answer:
For a volume of 60 ounces, the appropriate price is $16
Step-by-step explanation:
Firstly, we need to determine the relationship between volume of popcorn and the price of bag.
Let us try and see if there is a linear relationship
A linear model is of the form ;
y = mx + b
where m is the slope and b is the y intercept
While the price represents the y axis values, the volume represents the x axis values
For the slope;
m = (y2-y1)/(x2-x1)
m = (13.6-11)/(48-35) = 2.6/13 = 0.2
So we have the slope value as 0.2
the equation is;
y = 0.2x + b
to get b, substitute any value of (x,y)
6 = 0.2(10) + b
6 = 2 + b
b = 6-2 = 4
If we had substituted (20,8)
8 = 0.2(20) + b
8 = 4 + b
b = 4
if (48,13.6)
13.6 = 48(0.2) + b
13.6 = 9.6 + b
b = 13.6-9.6
b = 4
Hence we have established linear relationship between the volume in ounces and the price in $
So we have this as
Price = 0.2(volume) + 4
So for volume of 60 ounces;
Price = 0.2(60) + 4
price = 12 + 4
price = $16
The reason why this is appropriate is because it follows the rule of the established linear relationship
Answer:
$16

What is the surface area of this figure?
15 in
10 in
10 in
Answer: 800
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
The surface area of the figure is 40 + 5π.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
From the figure,
We have a semicircle and a rectangle.
Now,
Diamter = 10 in
Radius = 5 in
Circumference = 2πr
Semicircle circumference = πr
Now,
The surface area of the figure.
= 15 + 10 + 15 + πr
= 40 + 5π
Thus,
The surface area of the figure is 40 + 5π.

Answer:
D ; y = (4/3)x + 2
Step-by-step explanation:
The general form of the equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
Now, let us represent the given equation in this general form
We have this as;
4y= -3x + 12
divide through by 4
y = -3/4x + 3
Now, the slope of this equation is -3/4
Mathematically, when two lines are perpendicular, the product of their slopes is -1
let us have the slope of the second equation as m2
-3/4 * m2 = -1
-3m2 = 4 * -1
m2 = -4/-3
m2 = 4/3
so, the equation that is perpendicular will have its slope as 4/3
Looking through the options given as we have the equations in the general form, the equation D is the correct answer
D ; y = (4/3)x + 2

Miguel compró 6 azulejos cuadrados cuya área es de 49 cm^2 cada uno y los ubicó en dos columnas de tres azulejos en la pared. ¿Cuál es el perímetro del rectángulo formado por estos azulejos en dicha disposición?
Answer:
the perimeter of the rectangle is 70 cm
Step-by-step explanation:
The computation of the perimeter of the rectangle is given below:
first we determine the side of each tile i.e.
l² = A
l² = 49cm²
l = √49cm²
l = 7cm
now we calculate the perimeter i.e.
P = 2 (3 (7cm) + 2 (7cm))
= 2 (21cm + 14cm)
= 2 (35cm)
= 70cm
Hence, the perimeter of the rectangle is 70 cm

f : its just another way of expressing the expression
g(x)=3x+2 and h(x)=ax+B
where a and b are constants
h(4)=22
g^-1(14)=h(1)
find the value of a and the value of b
Answer:
a=6
b=-2
Step-by-step explanation:
You can use the hint provided on the mathswatch question page, I've attached it below
step 1
h(4) = ax+b = (ax4)+b = 4a+b
it is given in the question that h(4)=22, therefore 4a+b=22
step 2
work out the equation for inverse g
g^-1(x) = [tex]\frac{x-2}{3}[/tex]
step 3
input 14 into the equation in place of x to find g^-1(x)
[tex]\frac{x-2}{3} =\frac{14-2}{3} =\frac{12}{3} =4[/tex]
so, g(x)^-1=4
step 4
find h(1):
h(1) = (ax1)+b = a+b
so, h(1)=a+b
step 5
a+b=4 (as it is given in the question that g^-1(14) is equal to h(1))
step 6
Now you have two simultaneous equations:
4a+b=22
a+b=4
then, solve for a:
4a+b=22
- a+b=4
3a=18
a=6
then, input answer for a into either equation (I've gone with the a+b=4 equation):
6+b=4
-6 - 6
b=-2

Answer: A) 20.9 ; B) 34years
Step-by-step explanation:
Given the following :
AGE (X) - - - - - - - 19 - -20 - - - 21 - - - 22 - - - 23
FREQUENCY (F) - 2 - - 3 - - - - 1 - - - - 4 - - - - 1
A)
MEAN(X) = [AGE(X) × FREQUENCY (F)] ÷ SUM OF FREQUENCY
F*X = [(19 * 2) + (20 * 3) + ( 21 * 1)+(22 * 4)+(23 * 1)]
= 38 + 60 +21 + 88 + 23 = 230
SUM OF FREQUENCY = 2 + 3 + 1 + 4 + 1= 11
MEAN(X) = 230 / 11
X = 20.9
B)
WHEN A NEW PLAYER WAS ADDED :
MEAN (X) = 22
Let age of new player = y
Sum of Ages = 19 + 19 +20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 + y
Number of players = 11 + 1 = 12
Mean(x) = sum of ages / number of players
New mean (x) = 22
x = (230 + y) / 12
22 = (230 + y) / 12
Cross multiply
264 = 230 + y
y = 264 - 230
y = 34 years
