Cheryl decorated a border of a birthday card with flowers. The flowers were 1/200 m apart. The length of the border was 1/5 m. There was a flower at each end of the border. How many flowers did she draw?
Answer:
She draw 40 flowers
Step-by-step explanation:
Given
[tex]Length = \frac{1}{5}m[/tex]
[tex]Flower = \frac{1}{200}m[/tex]
Required
Determine the number of flowers
To do this, we simply divide the length of the border by the length of the flower.
[tex]Number = \frac{1}{5}/ \frac{1}{200}[/tex]
Convert to multiplication
[tex]Number = \frac{1}{5}* \frac{200}{1}[/tex]
[tex]Number = \frac{200}{5}[/tex]
[tex]Number = 40[/tex]
Hence, she draw 40 flowers
You roll a fair six sided cube and flip a coin. What is the probability that you roll an even number and the coin lands on tails?
Answer: Since flipping a coin and rolling a 6-sided die are independent events ,thus the probability of getting head and an even number is just the product of the individual probability of events.
Let A be the event of getting a head ,and B be the event of getting an even number on die.
therefore, P(A and B)=P(A) P(B)=(1/2)*(3/6)=1/4=0.25.

The table below shows the number of strawberries and cups of water
used to make fruit punch according to a certain recipe.
Strawberries Water (cups)
384
30
320
25
How many cups of water are needed for every 1 strawberry? Note:
Your answer may be exact or rounded to the nearest hundredth.
Answer:
5/64 of a cup.
Step-by-step explanation:
Is there two columns of data and two data points? Like this:
Strawberries Water
384 30
320 25
If so, then there are two ways to do it.
1) You can set up a ratio like this
384/30 = 1/x
Where x is the number of cups of water for 1 strawberry.
So,
x = 30/384 of a cup
x = 5/64 of a cup.
2) Look at the increase from one to the other.
64 strawberries requires 5 cups of water
Divide by 5 by 64 to get the water for one strawberry
5/64 of a cup.

Triangle ABC is shown. DE is a straight line with D on AC and E on BC AB = 46m, EC = 18m, CD = 29m and ED = 20m. Calculate the length AD.
Answer:
37.7m
Step-by-step explanation:
Triangle ABC is shown. DE is a straight line with D on AC and E on BC AB = 46m, EC = 18m, CD = 29m and ED = 20m. Calculate the length AD.
We solve using Similarity Theorem
BA/AC =BD/DC
46/AD+29 = 20/29
Cross Multiply
46 × 29 =20 (AD + 29)
1334 = 20AD + 580
20AD = 1334 - 580
20AD = 754
AD = 754/20
AD = 37.7m

Answer:
x = 60y = 50Step-by-step explanation:
The linear pair at G totals 180°, so we have ...
x + 2x = 180
3x = 180 . . . . . collect terms
x = 180/3 . . . divide by 3
x = 60
__
The total of angles in the triangle is 180°, so ...
x + y + 70 = 180
60 + y + 70 = 180 . . . . substitute for x
y = 180 -130 . . . . . . . . . subtract 130
y = 50

Thomas drew a line of best fit for the scatter plot as shown. Enter an equation for the line of best fit in slope-intercept form. The line of best fit equation in slope-intercept form is y =
Answer:
Equation of line best fits the scatter plot is y = [tex]-\frac{30}{7} x + 108[/tex]
Step-by-step explanation:
Let the equation of line be y = mx + c
where m = slope of line and c is the intercept on y -axis
from the graph intercept on y-axis is 108
and the slope of line is given by m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] where ([tex]x_2,y_2[/tex]) and ([tex]x_1,y_1[/tex]) is the points on line
let, points be (4,96) and (18,36)
on calculating this m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = [tex]-\frac{30}{7}[/tex]
Therefore equation of line best fits the scatter plot is y = [tex]-\frac{30}{7} x + 108[/tex]
In a two-digit number, the unit's digit is 2 more than that of the ten's digit. The sum of the digits is 27 less than the number. Find the product of the digits of the number
Answer:
15 is the product of the digits of the number
Step-by-step explanation:
Let the two digit number be xy
Unit digit is 2 more than ten’s digit
y - x = 2 ••••••(i)
Secondly;
x + y = (10x + y) - 27 •••••(ii)
From i, y = x + 2
Put this into ii
x + x + 2 = 10x + x + 2 - 27
2x + 2 = 11x - 25
11x - 2x = 25 + 2
9x = 27
x = 27/9
x = 3
From above;
y = x + 2
y = 3 + 2 = 5
The product of the numbers xy will be 5 * 3 = 15

if p=3+2√2 find the values of p+1/p
Answer: 1,71572875
Step-by-step explanation: (4+2rad2)/3+2rad2
Answer:
6
Step-by-step explanation:
1/p = 1/(3 + 2sqrt2)
Multiplying by the conjugate (which you should pretty much always do to simplify), we get
(3-2sqrt2)/((3+2srqt)(3-2sqrt2))
which is
(3-2sqrt2)/(9-8) = 3-2sqrt2.
Therefore p + 1/p = 3+2sqrt2 + 3 - 2sqrt2 = 6

Jan creates a pattern using the rule "add 3". Bill creates pattern using the rule "add 6." Which describes the relationship between Jan and Bill's patterns?
Answer: a. Each term in Bill's pattern is twice the value of the corresponding item in Jan's pattern.
Step-by-step explanation:
Jan created a pattern by adding 3 and Bill created a pattern by adding 6.
6 is twice the value of 3 so Bill's terms will be twice the value of Jan's corresponding terms as well.
To prove it:
12 is twice the value of 6
18 is twice the value of 9
24 is twice the value of 12

Find the value of x.
Answer:
x = 132°
Step-by-step explanation:
sum of total exterior angles = 360°
x + 147° + 81° = 360°
x + 228° = 360°
x = 360° - 228°
x = 132°
