Answer:
9 months
Step-by-step explanation:
Given
Fabulous fitness charges a one-time fee of $90 and an additional $25 per month
let the number of months be x
and the total charges be y
y= 25x+90---------1
Wonder weights charges a one-time fee of only $ 27 dollars but charge an additional $32 each month
let the number of months be x
and the total charges be y
y= 32x+27------------2
Required
The value of x, that is the number of months
Step two:
Equating both equations we have
25x+90=32x+27
collect like terms
25x-32x=27-90
-7x=-63
7x=63
divide both sides by 7
x= 63/7
x= 9 months
you note that the recipe calls for two cups of butter and three eggs (plus the other ingredients) to make six dozen cookies. you call a friend and have him bring you some eggs.
The number of cookies prepared from 1.33 cups of butter are 48.
What is ratio and proportions?A ratio in mathematics signifies how many one number appears to contain another. For instance, when there are eight oranges as well as six lemons in a fruit bowl the orange-to-lemon ratio is eight to six, or 8:6, which really is similar to the proportion 4:3.
Now, as per the given question.
In this item, we have been asked to calculate the total number of cookies that may be made by having;
Let 'x' be the cookies made by 1.33 cups of butter.
When, six dozen cookies with 2 cups of the butter = 72 cookies with 2 cups of the butter.
We will use the ratio & proportion formula to solve this problem:
a/b = c/d
Let us now enter the values:
72 cookies/ 2 cups of butter = x / 1.33 cups of butter
Cross multiplying the equations;
72 cookies × 1.33 cups of butter = x × 2 cups of butter
Thus,
x = (72 cookies × 1.33 cups of butter)/2 cups of butter
x = 48
Thus, 48 cookies will be made in proportion to 1.33 cup butter.

A truck can be rented from Company A for $40 a day plus $0.30 per mile. Company B charges $20 a day plus $0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
The number of miles in a day at which the rental costs for Company A and Company B are the same is 200 miles per day
Let the truck is driven X miles per day
Charges of company A will be = 90+0.4X
Charges of company B will be =30+0.7X
Let us find out value of X when charges of both companies are same
which means that 90+0.4 X= 30+0.7X
90-30 = 0.7X-0.4X
60 = 0.3X

2 2/7:(0.6x)=4/21:0.25
Answer:
x = 5
Step-by-step explanation:
Given:
[tex]2 \frac{2}{7}:(0.6x)=\dfrac{4}{21}:0.25[/tex]
Convert the mixed number into an improper fraction by multiplying the whole number with the denominator of the fraction, adding it to the numerator of the fraction, and placing it all over the denominator of the fraction:
[tex]\implies 2\frac{2}{7}=\dfrac{2 \times 7+2}{7}=\dfrac{16}{7}[/tex]
Therefore:
[tex]\implies \dfrac{16}{7}:(0.6x)=\dfrac{4}{21}:0.25[/tex]
[tex]\implies \dfrac{\frac{16}{7}}{0.6x}=\dfrac{\frac{4}{21}}{0.25}[/tex]
Cross multiply:
[tex]\implies \dfrac{16}{7} \times 0.25 = \dfrac{4}{21} \times 0.6x[/tex]
[tex]\implies \dfrac{16\times 0.25}{7} = \dfrac{4\times 0.6x}{21}[/tex]
[tex]\implies \dfrac{4}{7} = \dfrac{2.4x}{21}[/tex]
Cross multiply again:
[tex]\implies 4 \times 21=2.4x \times 7[/tex]
[tex]\implies 84=16.8x[/tex]
Divide both sides by 16.8:
[tex]\implies \dfrac{84}{16.8}=\dfrac{16.8x}{16.8}[/tex]
[tex]\implies 5=x[/tex]
[tex]\implies x=5[/tex]
Answer:
The value of x is 5.
Step-by-step explanation:
Let's solve for the value of x,
→ 2 2/7 : (0.6x) = 4/21 : 0.25
→ 16/7 : (0.6x) = 4/21 : 0.25
→ (16/7) × 0.25 = (4/21) × 0.6x
→ 4/7 = (2.4x)/21
→ 2.4x × 7 = 4 × 21
→ 16.8x = 84
→ x = 84/16.8
→ [ x = 5 ]
Hence, the value of x is 5.
Find the area of ABC with vertices A(4, -3) B(9,-3) , and C(10, −11)
The area of triangle ABC with vertices is 22 square units
How to find the area of ABC with vertices?The vertices are given as:
A(4, -3) B(9,-3) , and C(10, −11)
The area of the triangle is calculated using
Area = 0.5 * |Ax(By - Cy) + Bx(Ay - Cy) + Cx(Ay - By)|
This gives
Area = 0.5 * |4 * (-3 + 11) + 9 * (-3 + 11) + 10 * (-3 - 3)|
Evaluate the sum of products
Area = 0.5 * |44|

is 9817 completely divisible by 3
Answer:
No
Step-by-step explanation:
To know if a number is completely divisible by 3, you can add up its digits. If its digits equal a number divisible by 3, then the number itself is divisible by 3.
9817

2 + 5
= 7
Since 25 isn't divisible by 3, 9817 isn't completely divisible by 3 either.

what is the soluton to the equation e^3x=12
Answer:
[tex]x=\frac{ln(12)}{3}[/tex]
Step-by-step explanation:
We can solve this equation by taking the natural log of both sides.
This gives us the equation: [tex]ln(e^{3x})=ln(12)[/tex]
And the definition of natural log is basically, "what do I have to raise e to, to get this result"
The result is just e^3x, so I have to raise e to what? Well that's just 3x, you could also use log properties to bring the exponent in front and realize ln(e) = 1
So this gives us: [tex]3x=ln(12)[/tex]
Now divide both sides by 3: [tex]x=\frac{ln(12)}{3}[/tex]

at $2\!:\!48$ what is the degree measure of the smaller angle formed by the hour and minute hands of a $12$-hour clock?
Angle between hour and minute hand= 204°
a figure which is formed by two rays or lines that shares a common endpoint is known as Angle.
The hour hand has covered 2 h and 48 min from position 12 o'clock (reference position). And in case of minute hand 22 min from reference. Required angle is angle covered by minute hand minus the angle covered by hour hand (clearly minute hand has covered greater angle in comparison with hour hand).
For calculating angle covered by minute hand:
In 60 min the min hand covers 360°
60 min = 360°
1 min = 6° ; 48 min = 288°
For calculating angle covered by hour hand:
12 h ( of hour hand) = 360°
1 h = 30°
For [2 + (48/60)] h, the angle covered= [2 + (48/60)]*30° = 84°
Angle between hour and minute hand = (288–84)° = 204°
It is the acute angle between hour and minute hand. For finding reflex angle subtract the obtained acute angle from 360°. So the reflex angle will be 299°.
Angle between hour and minute hand= 204°

What is rate of change?
A rate in mathematics is the comparison of two related values expressed in different units. The numerator of the ratio indicates the rate of change in the other (dependent) variable if the denominator of the ratio is written as a single unit of one of these quantities, and if it is assumed that this quantity may be modified systematically (i.e., is an independent variable).
"Per unit of time" is a frequent sort of rate, and examples include speed, heart rate, and flux. Exchange rates, literacy rates, and electric field ratios are examples of ratios with a non-time denominator (in volts per meter).
The word "per" is used to denote the division of the units of the two measurements that make up a rate when discussing its units (for example a heart rate is expressed "beats per minute"). A rate that is defined using two numbers of the same units will provide a dimensionless quantity that can be stated as a percentage (for instance, the global literacy rate in 1998 was 80%), fraction, or multiple. Examples of these rates include tax rates and literacy rates.
