Biscuits
Ingredients to make 16 biscuits
175 g of butter
75 g of sugar
250 g of flour
Anna has
500 g of butter
300 g of sugar
625 g of flour
Work out the greatest number of biscuits Anna can make.
Answer:
40 biscuits
Step-by-step explanation:
Here are the ingredients needed to make 16 biscuits.
From the above question
Ingredients to make 16 biscuits
175 g of butter
75 g of sugar
250 g of flour
Anna has
500 g of butter
300 g of sugar
625 g of flour
To find the greatest number of biscuits she can make:
For flour
250g of butter = 16 biscuits
625g of butter = x
Cross Multiply
250x = 625 × 16
x = 625 × 16/250
x = 40 biscuits

9. a) Why does every pair of whole
a
numbers have a GCF of 1 or greater?
Answer:
A whole number is any positive integer greater than zero and is not a fraction or a decimal. Any whole number can be divided by itself and one so therefor all pairs of whole numbers have a GCF of one. However the bigger the number the more factors it can have so the GCF of a pair of whole numbers may have a greater GCF than 1.

What is the range of the function f(x) = -4|x + 1| − 5?
A. (-∞, -5]
B. [-5, ∞)
C. [-4, ∞)
D. (-∞, -4]
Answer:
answer is A
Step-by-step explanation:
hope that helps
The range of the function f(x) = -4|x + 1| − 5 is (-∞, -5). The correct option is A.
What are a domain and range?The domain of a function is the set of values that can be plugged into it. This set contains the x values in a function like f. (x). A function's range is the set of values that the function can take. This is the set of values that the function returns after we enter an x value.
The given function is f(x) = -4|x + 1| − 5. Plot the function on the graph and it is observed that the range of the function varies from -∞ tp 5.
The graph of the function is attached with the answer below. The absolute function has the vertex at (-1,-5).
Therefore, the range of the function f(x) = -4|x + 1| − 5 is (-∞, -5). The correct option is A.

Which represents a quadratic function?
Answer:
B
Step-by-step explanation:
a is a cubic. A cubic is an equation that has 3 on its base x to become x^3 as it's highest power. That is not a quadratic. A cubic and a quadratic are not the same thing.
b is a quadratic The highest power is 2 on the base (x) to become x^2. That is how a quadratic is defined.
c is a reciprocal. It has its highest power in the denominator, and that is not a quadratic. A quadratic is an equation whose highest power is 2 on its base (x) and whose highest power is in the numerator, not the denominator. This choice is rather tricky because the quadratic formula can be used on it if you change x = 1/z. Then the equation becomes f(x) = 4z^2 - 2z + 1. But as it is given and likely as you have been told, this is not a quadratic. This will factor into (2z - 1)(2z - 1). If I were a student, I'd question this one. It would be interesting to see how your instructor would eliminate it.
d is just a linear function. Since x^2 is multiplied by 0, it disappears. What is left is f(x) = -9x + 7 which is a linear function.
Gina had 1/2 a liter of Dr. Pepper. She gave 2/5 of a liter to her friend. How much does she have left?
Answer:
1/10
Step-by-step explanation:
1) find a common factor between the two denominators.
2 and 5 have a common factor of 10. you can find this by multiplying the denominators.
2) now that you have a common denominator of 10, you'll need to change the numerators too. you do this by finding out how many times the denominator goes into your common factor. 5 goes into 10 two times so you would multiply 2 x 2. two goes into 10 five times so multiply 5 x 1.
3) you now have both fractions that share a common factor. now you have to subtract them.
5/10 - 4/10 = 1/10

Why didn't some materials Sink in water and some others didn't?
Answer: Materials sink in water depending on how heavy they are. It is about how heavy something is compared to the same amount (volume) of water. This ratio of an object’s mass to its volume is known as density. Density is what really determines whether something will sink or float.

find the value of X such that the data set has a mean of 118. 101, 119, 104, 115, 109, x
Answer:
160
Step-by-step explanation:
101+119+104+115+109+x=548+x
there are 6 terms including x so divide the sum by 6
(548+x)/6=118
multiply both sides by 6
548+x=708
subtract 548
x=160
hope that helps :)
Answer:
160
Step-by-step explanation:
There are 6 numbers in the set
101 + 119 + 104 + 115 + 109 + x = 6(118)
101 + 119 + 104 + 115 + 109 + x = 708
548 + x = 708
-548 -548
x = 160

The `| |` symbols mean actual value, which makes every number inside of it positive. That would mean, following the rules of actual value, the equation would look like:

The math teachers decided to throw a party. One teacher bought 7 cookies and 2 ice cream bars for $10.95. Another teacher bought 4 cookies and 3 ice cream bars for $10.25 . How much did one cookie and one ice cream bar cost, individually?
Answer:
0.95, 2.15
Step-by-step explanation:
cookie-x
ice bar-y
7x+2y=10.95 (*3)
4x+3y=10.25 (*2)
21x+6y=32.85
8x+6y=20.5
21x-8x=32.85-20.5=12.35
13x=12.35
x=0.95
2y=10.95-7*0.95=4.3
y=2.15

sequence
What is a1, in thousands?
What is r?
Answer:
400
1.05
Step-by-step explanation:
The athlete should take the second offer.
It is given by the formula,
A = P(1+r)ⁿ
where A is the value after n period of time, P is the initial amount, and,
r is the rate of increment or decrement.
Now, Total amount = $400,000(1+5%)⁷
= $400,000(1+0.05)⁷
= $400,000(1.4071)
= $562840.17
Now, the total amount that the pro-athlete will get in 8 years is,
Total amount = $425,000(1+4%)⁷
= $425,000(1+0.04)⁷
= $425,000(1.3159)
= $559,271
Since the total amount that the athlete will get in the next 8 years is more for the second offer, the athlete should take the second offer.

Do note that this question might have two answers as Square roots will actually give you a positive and negative solution. Clarify with your teacher about this.
Answer:
x=0.09765625 or rounded up as 0.1
Step-by-step explanation:
first you have to add 25 to the 0 and subtract it from the sid it is on. making it look like this
16x²=25
256x=25
now divide both sides by 256 and you get
x=0.09765625 or rounded up as 0.1
