Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

Answer:x=1 1/2
Step-by-step explanation:
equation 3/4=.5x
you have to divide 3/4 and .5 by .5
3/4 divided by .5=
3/4 divided by 1/2=

what is the radius of a button if the circumference is 3 1/2 in
Answer: 0.557 in
Step-by-step explanation:
We will use the formula for the circumference of a circle, substitute known values, and solve for r (radius). 3 1/2 = 3.5.
Given:
C = 2πr
Substitute known values:
(3.5) = 2πr
Divide both sides of the equation by 2π:
(3.5) = 2πr
r = 0.557 in

Triangle XYZ is similar to triangle JKL.
triangle XYZ with side XY labeled 8.7, side YZ labeled 7.8, and side ZX labeled 8.2 and triangle JKL with side JK labeled 10.44
Determine the length of side LJ.
8.79
9.36
9.84
10.13
Answer:
C) 9.84
Step-by-step explanation:
JK ~ XY
XY = 8.7
JK = 10.44
10.44/8.7 = 1.2
That’s the scale or dilation
LJ ~ ZX
ZX = 8.2
8.2 X 1.2 = 9.84
LJ = 9.84
The length of side LJ in the triangle JKL is 9.36.
We are given that triangle XYZ is similar to triangle JKL, which means that the corresponding sides are proportional.
We are also given the lengths of the sides of triangle XYZ, so we can use these lengths to find the corresponding sides of triangle JKL.
The ratio of the corresponding sides of triangle XYZ to triangle JKL is:
XY : JK = 8.7 : 10.44
YZ : KL = 7.8 : 9.36
ZX : LJ = 8.2 : x
Since the two triangles are similar, we know that the ratios of the corresponding sides are equal.
Therefore, we can set the two ratios equal to each other and solve for x, the length of side LJ:
8.7 / 10.44 = 7.8 / 9.36 = 8.2 / x
Cross-multiplying, we get:
8.7 * x = 10.44 * 7.8
x = (10.44 * 7.8) / 8.7
x = 9.36
Therefore, the length of side LJ is 9.36.

Evaluate the expression 2^x − x^2 for x=5.
Answer:
To evaluate the expression 2^x − x^2 for x=5, we need to substitute 5 for x and simplify. Using the order of operations, we get:
2^x − x^2
= 2^5 − 5^2
= 32 − 25
= 7
So, the expression 2^x − x^2 evaluates to 7 when x=5.

Answer:
Play soccer: _________67% / 33% / 100%
Do not play soccer:___ 45% / 55% / 100%
Total : _____________112% / 88% / 200%
Step-by-step explanation:
play soccer: total is 90, to find percentage :
60/90 = 0.6666666667 estimated = 0.67
0.67 x 100 = 67%
30/90 = 0.3333333333 estimated = 0.33
0.33 x 100= 33%
33% + 67% = 100%
don’t play soccer : total is 60, to find percentage:
27/60 = 0.45
0.45 x 100 = 45%
33/60= 0.55
0.55 x 100 = 55%
45% + 55% = 100%
Total for first column going down
67% + 45% = 112%
Second column going down
33% + 55%= 88%
Third column going down
100% + 100% = 200%
Third column going across
112% + 88%= 200%
Play soccer: 67% / 33% / 100%
Do not play soccer:45% / 55% / 100%
Total :112% / 88% / 200%

Which of the following circle graphs correctly represents the data in the table?
Choice A: a circle graph titled social media usage, with four sections labeled headbook 17 percent, picturegram 48 percent, tweeter 25 percent, and vidtok 10 percent
ChoiceB: a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Choice C: a circle graph titled social media usage, with four sections labeled tweeter 17 percent, vidtok 48 percent, headbook 25 percent, and picturegram 10 percent
ChoiceD: a circle graph titled social media usage, with four sections labeled picturegram 17 percent, tweeter 48 percent, vidtok 25 percent, and headbook 10 percent
Answer:
The answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Step-by-step explanation:
By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.
85 ÷ 5 = 172
40 ÷ 5 = 48
125 ÷ 5 = 25
50 ÷ 5 = 10
Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
what is the perimeter of a stained glass semi-circle if the diameter is 3 feet?
Answer:
The perimeter of the stained glass semi-circle is 3π feet.
Step-by-step explanation:
The perimeter of a semi-circle is half of the circumference of the full circle with the same diameter.
The circumference of a circle with diameter 3 feet is:
C = πd = π(3) = 3π feet
Therefore, the circumference of the full circle is 3π feet, and the circumference of the semi-circle is half of that:
C(semi-circle) = 1/2(3π) = 3/2π feet
However, the stained glass semi-circle has a curved edge, so we need to add the length of that edge to the perimeter. The curved edge of a semi-circle is half of the circumference of the full circle, or:
C(curved edge) = 1/2(2πr) = πr, where r is the radius of the circle
Since the diameter of the circle is 3 feet, the radius is half of that:
r = d/2 = 3/2 feet
So the curved edge of the stained glass semi-circle is:
C(curved edge) = π(3/2) = 3/2π feet
Adding this to the straight edge perimeter, we get:
Perimeter = C(semi-circle) + C(curved edge)
= (3/2π) + (3/2π)
= 3π feet
Therefore, the perimeter of the stained glass semi-circle is 3π feet.

Answer:
Airplane A has a lesser Interquartile range.
Step-by-step explanation:
To find the interquartile range, subtract the lower quartile from the upper quartile.
Airplane A = Upper quartile - lower quartile
Airplane A = 225 - 209 = 16
Airplane B = Upper quartile - lower quartile
Airplane B = 230 - 205 = 25
Therefore airplane a has a lesser interquartile range.
