Answer:
The equation would help determine the cost 1 rubber stamps will be:
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
Step-by-step explanation:
Let x be the cost of 11 rubbers.
As the cost of 5 rubber stamps is $9.70.
Thus, the cost of 11 rubbers can be determined using the proportional ratios.
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
BONUS! let us solve to check
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
switch sides
[tex]\frac{x}{11}=\frac{9.7}{5}[/tex]
Multiply both sides by 11
[tex]\frac{11x}{11}=\frac{9.7\cdot \:11}{5}[/tex]
Simplify
[tex]x=21.34[/tex]
Thus, the cost of 11 rubber stamps: x = $21.34
Therefore, the equation would help determine the cost 1 rubber stamps will be:
[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]
VERIFICIATIONGiven
The cost of 5 rubber stamps = $9.70
Thus,
The cost of 1 rubber stamps = 9.70 / 5
= $1.94
If the cost of 1 rubber stamp = $1.94
The cost of 11 rubber stamps = 11 × 1.94
= $21.34

None of the above

thank you
The percentage of questions did Tomi know the answer for is,
⇒ 90%
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
We have to given that;
Out of 30 questions on the math's test Tomi knew the answer to 27 of them.
Hence, The percentage of questions did Tomi know the answer for is,
⇒ 27/30 × 100
⇒ 90%
Thus, The percentage of questions did Tomi know the answer for is,
⇒ 90%

If f(x)=3^ x-4 what is f(- 1) ?
Answer:
1/243
Step-by-step explanation:
When you see this notation, it means plug in -1 for x in the function.
f(-1) = 3^((-1)-4)
f(-1) = 3^-5
f(-1) = 1/3^5
f(-1) = 1/243
Step-by-step explanation:
substitute (-1)

White shapes and black shapes are used in a game.
Some of the shapes are circles.
All the other shapes are squares.
The ratio of the number of white shapes to the number of black shapes is 3 : 7
The ratio of the number of white circles to the number of white squares is 4 : 5
The ratio of the number of black circles to the number of black squares is 2 : 5
Work out what fraction of all the shapes are circles.
Answer:
Find the equivalent ratio for the total shapes:
Total Black Shapes : Total White Shapes = 5 : 11
Multiply by 2:
Total Black Shapes: Total White Shapes = 10 : 22

Jacob has 17 yards of fabric. He uses 1 third of it to make a cape. How many yards of fabric does Jacob use for the cape? Solve on paper. Write your answer as a mixed number. 17 yards ? Jacob uses yards of fabric for the cape.
Answer:
Joseph used [tex]5\frac{2}{3}\ yards\ of\ cape[/tex]
Step-by-step explanation:
Total fabric available = 17 yards
fraction used = one-third = 1/3
Let us convert this fraction to actual number
He used one-third of total
= [tex]\frac{1}{3}\ of\ 17\\=\frac{1}{3} \times \frac{17}{1} = \frac{17}{3}[/tex]
To convert to mixed number, look for the closest number to the numerator that the denominator in the fraction can divide, and write it as the whole number in the mixed fraction, the remainder becomes the numerator of the new fraction:
The closest number to 17 that 3 can divide without a remainder is 15 and 3 can divide 15, 5 times, while the remainder becomes 2
[tex]\therefore \frac{17}{3} = 5\frac{2}{3}\ yards\ of\ cape[/tex]

A park is in the shape of a rectangle 300 feet long 50 feet wide Amaya is standing at one corner of the park at point x he then walks in a straight line to the opposite corner at point y how far does he walk rounded to the nearest tenth
Answer:
[tex]304.1\ \text{feet}[/tex]
Step-by-step explanation:
The dimensions of the rectangle are 300 feet long 50 feet wide
The length between [tex]x[/tex] and [tex]y[/tex] will be the length of the diagonal of the rectangle.
Length of the diagonals can be found using the Pythagoras theorem
[tex]\sqrt{300^2+50^2}=304.138\approx 304.1\ \text{feet}[/tex]
The distance walked from [tex]x[/tex] to [tex]y[/tex] is [tex]304.1\ \text{feet}[/tex].
