in a survey of 600 adults , 15 % did not know how to ride a bike. how many people can ride a bike? plz I don't really understand this thank u for answering the question SHOW UR WORKING OUT
Answer:
510
Step-by-step explanation:
510 adults can ride a bike out of 600.
We can do this by first taking 15% of 600. To calculate 15% of 600, simply divide the percent (in this case, 15) by 100 and multiply by the number (600). For example, 15 ÷ 100 x 600 = 90, which means the same as 0.15 x 600 = 90.
Now that we know how many adults can't ride a bike, we take 600 and subtract that number from it. So, 600 - 90 = 510, which is how many adults can ride a bike.
Hope this helped! :)
If Sam visits an average of about 1.5 houses per minute for Trick-or-Treating, how many houses could she visit in a half hour? She could visit (your answer) houses
Answer:
45
Step-by-step explanation:
to get the answer you need to multiply 1.5×30
the reason there is 30 is because every hour has 60 minutes in it and a halp of an hour is 30 minutes. So your answer would be 45

Here are three different recipes for Orangey-Pineapple Juice. Two of these mixtures taste the same and one tastes different. Which two recipes will taste the same, and which one will taste different? Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Answer:
recipe 1 and recipe 2 will taste the same because they have the same ratio while recipe 3 will taste differently because it has a different ratio.
Step-by-step explanation:
Here are three different recipes for Orangy-Pineapple juice. Two of these mixtures taste the same and one tastes different.
Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Recipe 2: Mix 6 cups of orange juice with 9 cups of pineapple juice
Recipe 3: Mix 9 cups of orange juice with 12 cups of pineapple juice
Which two recipes will taste the same, and which one will taste different? explain or show your reasoning.
Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Ratio of orange juice to pineapple juice = 4 : 6
= 4 / 6
= 2/3
= 2 : 3
Recipe 2: Mix 6 cups of orange juice with 9 cups of pineapple juice.
Ratio of orange juice to pineapple juice = 6 : 9
= 6 / 9
= 2 / 3
= 2 : 3
Recipe 3: Mix 9 cups of orange juice with 12 cups of pineapple juice
Ratio of orange juice to pineapple juice = 9 : 12
= 9 / 12
= 3 / 4
= 3 ; 4
Therefore, recipe 1 and recipe 2 will taste the same because they have the same ratio while recipe 3 will taste differently because it has a different ratio.
What is the most efficient first step to isolate the variable term on one side of this equation?

Add 5 to both sides.
O Subtract 9x from both sides.
O Add 4x to both sides.
Answer:
add 4x to both sides

Beth had 1 yard of ribbon. She used 1_ 3 yard for a project. She wants to divide the rest of the ribbon into 1_ 6 yard pieces. How many 1_ 6 yard pieces of ribbon can she make? Explain your solution.
Given:
Total ribbon beth had = 1 yard
Ribbon used for project = [tex]\dfrac{1}{3}[/tex] yard
She wants to divide the rest of the ribbon into [tex]\dfrac{1}{6}[/tex] yard pieces.
To find:
The number of [tex]\dfrac{1}{6}[/tex] yard pieces of ribbon she can make.
Solution:
Total ribbon beth had = 1 yard
Ribbon used for project = [tex]\dfrac{1}{3}[/tex] yard
Remaining ribbon is
[tex]1-\dfrac{1}{3}=\dfrac{2}{3}[/tex]
She wants to divide the rest of the ribbon into [tex]\dfrac{1}{6}[/tex] yard pieces.
Let the number of [tex]\dfrac{1}{6}[/tex] yard pieces of ribbon she can make be x.
[tex]\dfrac{1}{6}x=\dfrac{2}{3}[/tex]
Multiply both sides by 6.
[tex]\dfrac{1}{6}x\times 6=\dfrac{2}{3}\times 6[/tex]
[tex]x=2\times 2[/tex]
[tex]x=4[/tex]
Therefore, number of [tex]\dfrac{1}{6}[/tex] yard pieces of ribbon she can make is 4.

The path of a projectile
launched from a 16-ft-tall tower
is modeled by the equation
y = −16x2 + 64x + 16. Graph the
equation. What is the maximum
height, in feet, reached by the
projectile?
(On a graph)
Answer:
The maximum height reached by the projectile is 80 feet
Step-by-step explanation:
The given equation of the path of the projectile is y = -16·x² + 64·x + 16
Where;
y = The height in feet, reached by the projectile (Assumption)
x = The time it takes the projectile to reach the height, y (Assumption)
The shape of the given equation of the path of the parabola is that of a parabola turned upside down.
We have that the maximum height is given by the top of the curve where the curve changes direction, and the slope = 0
Therefore, we have;
[tex]Slope = \dfrac{\mathrm{d} y}{\mathrm{d} x} = \dfrac{\mathrm{d} \left (-16\cdot x^2 + 64\cdot x + 16 \right )}{\mathrm{d} x} = -32 \cdot x + 64 = 0[/tex]
Therefore, at the maximum point, the slope is -32·x + 64 = 0
∴ x = -64/(-32) = 2 at the maximum point
The height at the maximum point = The maximum height, [tex]y_{max}[/tex], is found by finding the value of y (the height) at x = 2 (the value of x at the maximum point)
Therefore, we have;
[tex]y_{max}[/tex] = -16 × 2² + 64 × 2 + 16 = 80 feet
The maximum height reached by the projectile, [tex]y_{max}[/tex] = 80 feet.
Answer:
The maximum height reached by the projectile is 80 feet

Step-by-step explanation:
You are going to plug in the x values to the equation.
f(-4)=-2(-4)-3 -> f(-4)=8-3 -> f(-4)=5
f(-2)=-2(-2)-3 -> f(-2)=4-3 -> f(-2)=1
f(2)=-2(2)-3 -> f(2)=-2-3 -> f(2)=-5
Then you are going to graph. Plot the points on the table (remember rise over run) and connect them with a straight line.

There were 120 entries for the Rogers County Library annual writing competition, and 12 of them were picked to be published. What percent of the entries were picked to be published
Answer:
10%
Step-by-step explanation:
In order to calculate the percentage of the entries that were picked we need to divide the number of picked entries to be published by the total number of entries that were received during the competition like so...
12 / 120 = 0.1
Now we simply multiply this value by 100 in order to turn this into a percentage value
0.1 * 100 = 10%
Therefore, we can now see that only 10% of the total entries were picked to be published.
