Answer:
Nora Won
Step-by-step explanation:
In a swimming contest you would go for the least time, so, let's see who had the least time:
20 = 20 (Tens places)
5 = 5 (Unit place)
0 < 4 (Tenths place)
So, Nora was the winner and she was faster than Rachel by 0.36 seconds

Select all the correct descriptors for the relationship
Answer:
Options (1), (3) and (5)
Step-by-step explanation:
Coordinates of D → (2, 2)
Coordinates of E → (1, 6)
Coordinates of F → (5, 7)
Coordinates of G → (6, 3)
Length of ED = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
= [tex]\sqrt{(2-1)^2+(2-6)^2}[/tex]
= [tex]\sqrt{17}[/tex]
Length of FG = [tex]\sqrt{(5-6)^2+(7-3)^2}[/tex]
= [tex]\sqrt{17}[/tex]
Length of GD = [tex]\sqrt{6-2)^2+(3-2)^2}[/tex]
= [tex]\sqrt{17}[/tex]
Length of EF = [tex]\sqrt{(1-5)^2+(6-7)^2}[/tex]
= [tex]=\sqrt{17}[/tex]
Since, all sides of the given quadrilateral are equal in length, quadrilateral will be a square.
Therefore, diagonals EG and DF will be perpendicular, equal in measure, congruent and will bisect each other.
Options (1), (3) and (5) are the correct options.

Answer:
a) 7 kmb) 298°Step-by-step explanation:
See attached diagram (not to scale).
All given details reflected.
a) Find the measure of XZ using the law of cosines:
y = √(5² + 3² - 2*5*3*cos 135°) = 7 km (rounded)b) Now using the law of sines find the measure of angle X:
7 / sin 135° = 5 / sin X sin X = 5 sin 135° / 7m∠X = arcsin (5 sin 135° / 7 ) = 28° (rounded)The bearing of Z from X is:
270° + 28° = 298°Here are five sums. Use the distributive property to write each sum as a product with two factors. 2+7 5−10 −2^2 +++ 2−1/2
Question:
Here are five sums. Use the distributive property to write each sum as a product with two factors.
[tex](a)\ 2a + 7a[/tex] [tex](b)\ 5z - 10[/tex] [tex](c)\ c - c^2[/tex] [tex](d)\ r + r+ r+ r[/tex] [tex](e)\ 2x - \frac{1}{2}[/tex]
Answer:
[tex](a)\ 2a + 7a = 9a[/tex]
[tex](b)\ 5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]
Step-by-step explanation:
Required
Apply distributive property
[tex](a)\ 2a + 7a[/tex]
Apply distributive property [Factor out a]
[tex]2a + 7a = a(2 + 7)[/tex]
[tex]2a + 7a = a(9)[/tex]
Open bracket
[tex]2a + 7a = a*9[/tex]
[tex]2a + 7a = 9a[/tex]
[tex](b)\ 5z - 10[/tex]
Express 10 as 5 * 2
[tex]5z - 10 = 5z - 5*2[/tex]
Apply distributive property [Factor out 5]
[tex]5z - 10 = 5(z - 2)[/tex]
[tex](c)\ c - c^2[/tex]
Express c as c * c
[tex]c - c^2 = c - c * c[/tex]
Apply distributive property [Factor out c]
[tex]c - c^2 = c(1 - c)[/tex]
[tex](d)\ r + r+ r+ r[/tex]
Express r as r * 1
[tex]r + r + r + r = r * 1 + r * 1 + r * 1 + r *1[/tex]
Apply distributive property [Factor out 1]
[tex]r + r + r + r = r(1+1+1+1)[/tex]
[tex]r + r + r + r = r * 4[/tex]
[tex]r + r + r + r = 4r[/tex]
[tex](e)\ 2x - \frac{1}{2}[/tex]
Express 2x as 4x/2
[tex]2x - \frac{1}{2} = \frac{4x}{2} - \frac{1}{2}[/tex]
Apply distributive property [Factor out 1/2]
[tex]2x - \frac{1}{2} = \frac{1}{2}(4x - 1)[/tex]

Which statement about the numbers 22.407 and 22.416 is true? 22.407 = 22.416 because the values of the 4 in the tenths places are equal. 22.407 > 22.416 because the value of the 7 in the thousandths place is greater than the value of the 6. 22.407 = 22.416 because the values of the 2 in the ones places are equal. 22.407 < 22.416 because the value of the O in the hundredths place is less than the value of the 1.
Answer:
22.407 < 22.416 because the value of the 0 in the hundredths place is less than the value of the 1.

What is the approximate diameter of a tire that will make 775 complete rotations in one mile? (Note: there are 5280 feet
in 1 mile)
Answer:
About 2.17 feet.
Step-by-step explanation:
Let d represent the diameter of the tire.
Then the circumference of the tire will be:
[tex]C=d\pi[/tex]
So, the tire will travel dπ miles after one rotation.
After 775 rotations, the total miles traveled should be 5280 feet. Thus:
[tex]775(d\pi)=5280[/tex]
Solve for d:
[tex]\displaystyle d=\frac{5280}{775\pi}[/tex]
Approximate:
[tex]d=2.1686...\approx2.17[/tex]
The circumference of the tire should be about 2.17 feet.

A photographer wants to use a scale factor of 2.5 to enlarge a picture. What will the area of the picture be after it is enlarged?
Answer:
area = 250 in²
Step-by-step explanation:
5 x 2.5 = 12.5 in
8 x 2.5 = 20 in
area = 20 x 12.5 = 250 in²

Answer:
The shoes now cost $5.60
Answer:
1.40
Step-by-step explanation:
100% = 3.50
To get to 60%, divide 100 by 1.6, so this is the scale factor.
3.50/1.6=2.1 (this we need to take away from og amount)
3.50-2.10= 1.40

Pls help complete for y=-7x +9 how do I do this
Answer:
You put the x in the x area and solve the problem.
For example:
For 0 you would do y=-7(0) + 9
Then if you do the math you get y = 9
Therefore, your answer is 9.
