Q.10...In a cookie mix, we find chocolate chip cookies, spice cookies, and ginger cookies in a ratio of 4 : 3 : 3. If a bag of the mix contains 33 ginger cookies, how many chocolate chip cookies are there?
Answer:
13.2
Step-by-step explanation:
Let 4x represent the chocolate chip cookies
Let 3x represent the spice cookies
Let 3x represent ginger cookies
4x + 3x + 3x = 33
10x = 33
x = 33/10
x = 3.3
Since 4x represents chocolate chip cookies
4 × 3.3
= 13.2
Hence there are 13.2 chocolate chip cookies
The length of a planet's orbit around a star is approximately 34,510,000 km.
It takes the planet about 1500 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf?
Answer:
change days to hours so 1500×24=36000
34510000÷36000=959kmh-1

Answer:
Maximum value of z = 21
Minimum value of z = -9
Step-by-step explanation:
We have to maximize/minimize the given equation for the given constraints as,
x ≥ -1
y ≤ -2x + 3
y ≥ -1
By using the graphing tool,
Corner points for the feasible region are,
A(-1, 5), B(-1, -1) and C(2, -1)
For A(-1, 5),
z = 4x + 5y = 4(-1) + 5(5)
= -4 + 25
= 21
For B(-1, -1),
z = 4(-1) + 5(-1)
= -4 - 5
= -9
For C(2, -1),
z = 4(2) + 5(-1)
= 8 - 5
= 3
Maximum value of z = 21
Minimum value of z = -9

The expression (x² + 3) / (x-3)(x-1) is the simplified form of the given expression. which is the correct answer would be an option (B).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given below as:
(x-3)/(x-1) + 6/(x-3)
To simplify the expression, we can first combine the terms that have a common denominator:
(x-3)²+ 6(x-1) / (x-3)(x-1)
We can simplify the expression further by using the fact that
(x² + 9 - 6x + 6x - 6) / (x-3)(x-1)
Combine the likewise terms and apply the arithmetic operation,
(x² + 3) / (x-3)(x-1)
Thus, the simplified expression is:
(x² + 3) / (x-3)(x-1)

Answer:
1566 units^2
Step-by-step explanation:
34×28=952
34×9=306
28×11=308
952+306+308=1566
Answer:
1259 sq units
Step-by-step explanation:
Area of rectanlge; (A=bh) A=34 x 28 = 952
Area of left triangle; (A=bh/2) A=(28 x 11) /2 = 154
Area of abovle triangle; (A=bh/2) A=(34 x 9) /2 = 153
Sum of area of all three figures = 1,259
In a survey of 3,400 people who owned a certain type of car, 1,700 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
50%
Step-by-step explanation:
Calculation for What percent of the people surveyed were satisfied with the car
Using this formula
Percentage of people satisfied=Owners of car/Numbers of people to buy the same car again
Let plug in the formula
Percentage of people satisfied=1,700/3,400 people*100
Percentage of people satisfied=0.5*100
Percentage of people satisfied=50%
Therefore the percentage of the people surveyed who were satisfied with the car is 50%

Christian is training for a swimming competition He starts swimming 10 ft. from the shore to his boat The table below represents the distance from the shore. f(z), as a function of time after z minutes of swimming.
Answer:
f(x) = 20x + 10
Step-by-step explanation:
(0 , 10) ; (3 , 70)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{70-10}{3-0}\\\\= \frac{60}{3}\\\\= 20[/tex]
y- intercept = 10
f(x) = mx + c
= 20x + 10
Put the following equation of a line into slope-intercept form, simplifying all
fractions.
8y-2x=-72
Answer:
y = 1 4 x − 9
Step-by-step explanation:
Write in slope-intercept form, y = m x + b .
Answer:
y = 1/4x - - 9
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
8y - 2x = -72
Step 2: Rewrite
Find slope-intercept form
Add 2x on both sides: 8y = 2x - 72Divide 8 on both sides: y = 1/4x - - 9The price of a computer was decreased by 7% to £500. What was the price before the decrease? Give your answer to the nearest penny.
Answer:
£ 537.63
Step-by-step explanation:
original price = 100%
selling price = 100% - 7% = 93% = £500
just do the proportion or ratio
[tex] \frac{100\%}{93\%} = \frac{original \: price}{500} [/tex]
OP = 500 x 100% / 93%
OP = £ 537.634
rounded to the nearest penny and become £ 537.63
