Answer:
So you have the ratio of
1 : 2 : 5
Soda water : fruit punch: ginger ale
You have to make 32 pints of this.
You can add up the ratio.
1 + 2 + 5 = 8
You’d have 8 ingredients in total.
32 pints so 32/8 = 4
Now you have each ingredient *4
1 * 4 = 4
2* 4 = 8
5* 4 = 20
SO 4 soda water, 8 fruit punch, 20 ginger ale.
To check you can add these up again and if they equal 32 then you got it.
Katy invests £14 000 in a savings account for 3 years.
The account pays simple interest at a rate of 1.5% per annum.
Calculate the amount in her savings account Katy will get at the end of the 3 years
Simple interest formula:
Total = start x ( 1 + rate x time )
Total = 14,000 x ( 1 + (0.015 x3))
Total = 14,000 x 1.045
Total = 14,630
Answer:
£14,630
Step-by-step explanation:
Simple interest formula: A = P(1 + rt)
where:
A = final amountP = principal amountr = annual interest rate (as a decimal)t = time (in years)Given:
P = £14,000r = 1.5% = 0.015t = 3 years⇒ A = 14000(1 + 0.015 · 3)
⇒ A = 14000(1.045)
⇒ A = £14,630
Jillian was asked to translate the expression 9 n into words. She wrote "a number increased by nine. " Which best describes the accuracy of Jillian’s answer? It is incorrect. The variable would come first in the expression "a number" (n) "increased by" ( ) "nine" (9). It is incorrect. The phrase "increased by" refers to the inequality symbol "greater than" (>), not addition. It is correct. A number increased by nine (n 9) is the same as nine increased by a number (9 n). It is incorrect. A number increased by nine refers to a multiplication expression (n times 9).
A number increased by nine (n + 9) is the same as nine increased by a number (9 + n), the correct option is C.

Which choices contain equivalent statements? Check all that apply.
Answer:
A C and E
Step-by-step explanation:
Edge
The choices that contain equivalent statements are:
a) ln 3x = 6 → 3x = e⁶
c) log 4x = 8 → 4x = 10⁸
e) 5.6554 = 10ˣ → log 5.6554 = x
To determine which choices contain equivalent statements, let's analyze each option one by one:
a) ln 3x = 6 → 3x = e⁶
This statement is true. It represents the inverse relationship between the natural logarithm (ln) and the exponential function with base e. Taking the exponential of both sides of the equation allows us to isolate the variable.
b) log 3x = 9 → 9x = 10³
This statement is not true. It seems to confuse the base of the logarithm. If the logarithm is not specified with a base, it is usually assumed to be base 10 (log base 10). In this case, the correct equivalent statement would be 3x = 10⁹.
c) log 4x = 8 → 4x = 10⁸
This statement is true. Similar to the previous option, assuming a base 10 logarithm (log base 10), the equivalent statement would be 4x = 10⁸.
d) 0.577 = e⁵ˣ → ln 5 = x / 0.577
This statement is not true. The equation given at the beginning, 0.577 = e⁵ˣ, cannot be transformed into the second equation using the properties of logarithms or exponentials. The two statements are unrelated.
e) 5.6554 = 10ˣ → log 5.6554 = x
This statement is true. It correctly represents the relationship between the logarithm and exponential functions. By taking the logarithm (base 10) of both sides of the equation, we can solve for x.
In summary, the choices that contain equivalent statements are:
a) ln 3x = 6 → 3x = e⁶
c) log 4x = 8 → 4x = 10⁸
e) 5.6554 = 10ˣ → log 5.6554 = x

HELP!! Rashida had 18 correct answers and 12 incorrect answers. What was Rashida's score? Each correct answer is worth 2 1/4 points, and each incorrect answer is worth -1/2 point.
Number of incorrect answers Rashida got = 12
Number of correct answers Rashida got = 18
Given :-
Points for each correct answer =
[tex] = 2 \frac{1}{4} [/tex]
Points for each incorrect answer =
[tex] = \frac{ - 1}{ \: \: \: 2} [/tex]
Points Rashida will get for her correct answers :-
[tex] = 2 \frac{1}{4} \times 18[/tex]
[tex] = \frac{(4 \times 2+ 1)}{4} \times 18[/tex]
[tex] = \frac{9}{4} \times 18[/tex]
[tex] = \frac{162}{4} [/tex]
[tex] = 40.5 \: points[/tex]
Points Rashida will get for her incorrect answer :-
[tex] = \frac{ - 1}{ \: \: \:2} \times 12[/tex]
[tex] = \frac{ - 12}{ \: \: \: \: \: 2} [/tex]
[tex] = - 6 \: points[/tex]
So , Rashida gets 40.5 points for her correct answer and -6 points for her incorrect answer .
Rashida's total score :-
[tex] = 40.5 + ( - 6)[/tex]
[tex] = 34.5 \: points[/tex]
Therefore , Rashida gets 34.5 points as her total score .
The overall score of Rashida will be 34.5 for the given exam.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Number of correct answers = 18
Points of correct answer = 2 1/4 = 9/4
Scores of correct answer = 18 × 9/4 = 40.5
Number of incorrect answers = 18
Scores of incorrect answer = 12 × (-1/2) = -6
Total score = 40.5 - 6 = 34.5
Hence "The overall score of Rashida will be 34.5 for the given exam".

Answer:
f = 8
Step-by-step explanation:
Apply the distributed property, so it now looks like this: 2f - 10 = 6Add 10 to each side, so it now looks like this: 2f = 16Divide each side by 2 to cancel out the 2 next to f. It should now look like this: f = 8I hope this helps!
Answer:
f=8
Step-by-step explanation:
Step 1: Distribute
2(f) + 2(-5) = 6
2f - 10 = 6
Step 2: Add 10 to both sides to get 2f alone
2f = 16
Step 3: Divide both sides by 2 to get f alone

A farmer builds a fenced-in, rectangular pen for goats to clear brush from a section of land. The
pen has three sides of fencing because the width of the pen sits against the side of a barn.
If the farmer has 180 feet of fencing, what dimensions maximize the area of the pen?
a. 40 ft by 100 ft
b. 45 ft by 45 ft
c. 45 ft by 90 ft
d. 50 ft by 65ft
The dimension that maximize the are of the pen is 45 ft by 90 ft.
Area of a rectanglearea = lw
where
l = length
w= width
Therefore,
perimeter of a rectangle = 2(l + w)
The barn is occupying one part of the rectangle . Therefore,
perimeter = 2l + w
180 = 2l + w
w = 180 - 2l
area = lw
Therefore,
area = l(180 - 2l)
area = 180l - 2l²
To maximize area
l = -b / 2a
l = - (180) / 2 × -2
l = -180 / -4
l = 45 ft
Therefore,
w = 180 - 2(45)
w = 180 - 90
w = 90 ft

[tex]x = 5[/tex]
So, the pair is
[tex](5,0)[/tex]
For point 3:
Take x = 10
Substitute 10 for x in [tex]3x - 5y = 15[/tex]
[tex]3(10) - 5y = 15[/tex]
[tex]30 - 5y = 15[/tex]

It is another way to represent the power of numbers and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.
[tex]\rm a^b=c\\\rm log_ac=b[/tex]
We have a logarithmic equation:
[tex]\rm q+log_2(6)=2q+2[/tex]
After simplification the above equation we get;
[tex]\rm q+log_2(6)=2q+2\\\rm q-2q=-log_2(6)+2\\\rm -q=-log_2(6)+2\\[/tex].....(1)
From the logarithmic table, we get the value of [tex]\rm log_2(6)[/tex]
[tex]\rm log_2(6)=2.5849[/tex]
Putting this value in equation (1), we get:
[tex]\rm -q=-log_2(6)+2\\\rm -q=-2.5849+2\\\rm -q=-0.5849\\\rm q=0.5849 \approx 0.585\\[/tex]

Step-by-step explanation:
Basically its 800 40 times.
Answer:
32,000
Step-by-step explanation:
First put 800 over 40
Second, multiply the 3rd zero by the first zero of 40
Multiply the 2nd zero by the same zero of 40
Multiply 8 by 4 and the result should be 800
Then you multiply 800 by 4.
0 x 4 is 0
0 x 4 is 0
8 x 4 is 32
(Make sure you add the zero from 40)
Put it together and you get 32,000
