Answer:
35%
Step-by-step explanation:
To figure out the percentage of bronze medals, we must figure out the percentages of the gold and silver medals first.
We already know that 45% of the medals were silver.
We know that 4 of the 20 medals were gold.
4/20 as a percentage would be 20/100, or 20%.
So, 20% of the medals were gold, and 45% of them were silver.
45% + 20% = 65%
100% - 65% = 35%
So, 35% of the medals awarded were bronze.

Suppose that the probability that your mail is delivered before 2 pm. 90. What is the probability that your mail will be delivered before 2 pm for two consecutive days? Give your answer as a decimal.
Thank you!
Answer:
Step-by-step explanation:
1. The probability that your mail is delivered before 2 pm is 0.9, so the probability that the mail is delivered at 2 pm or after 2 pm (so not before 2 pm) is 1-0.9=0.1.
Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%
2. Probability of the mail being delivered before 2 pm for 2 consecutive days is

Which of the following could represent the relationship between the amount of sugar and water Candace should use in the mixture?
Answer:
the first image (the image with the upward sloping line)
Step-by-step explanation:
If the amount of sugar used in the mixture is proportional to the amount of water used, as more water is used, the more sugar is used. So, as more water is used, more sugar is used.
If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line
Write the measure in descending order 0.5m - 480mm - 55cm
Answer:
480mm<55cm<0.5m
Step-by-step explanation:
millimeters means 100
centimeters means 10
meters means 1
there are 10mm in every 1cm and 100cm in every 1m
Answer:
55cm>0.5m>480mm
Step-by-step explanation:
as we know
1000mm=1m
100cm=1m
So we see
55=55cm
0.50=50cm
480=48cm

A forest covers 73,000 acres. A survey finds that 0.2% of the forest is old-growth trees. How many
acres of old-growth trees are there?
There are acres of old-growth trees.
Type an integer or a decimal)
Answer:
143 acres.
Step-by-step explanation:
To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.
To find a percent of a number, multiply the percent by the number.
0.2% is equal to 0.002.
73,000 x 0.002 = 143
So, 143 acres of the forest is old-growth trees.

The points represented by the (x, y) coordinate pairs all lie on line "k". These are the points: (1,3), (2, 1), (3,-1). (4.-3), and (5,-5). What is the slope of line k? A.2 B.5 C.-3 D.-2
Answer:a
Step-by-step explanation:
Bsnanna
If the points (1,3), (2, 1), (3,-1). (4.-3) lie on line k, then the slope of line k is -2
Option D is the correct choice
The points that lie on the line k are:
(1,3), (2, 1), (3,-1). (4.-3), and (5,-5).
We can find the slope of the line k by picking any two points on the line
The slope m of a line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
On the line k, let us select the points (1,3) and (2, 1)
x₁ = 1, y₁ = 3, x₂ = 2, y₂ = 1
[tex]m = \frac{1-3}{2-1} \\\\m= \frac{-2}{1}\\\\m= -2[/tex]
Therefore, the slope of the line k is -2

The common ratio of a geometric sequence is 3 and the 8th term is 4,374. What is the 4th term in this sequence?
Answer:
the first term is a1
the 8th term is a8
the 4th term is a4
we have:
[tex]a8=a1.3^{7}\\\\<=>4374=a1.3^{7}\\\\<=>a1=2[/tex]
with a1 = 0,002 => a4 = a1.3³ = 2.27 =54
Step-by-step explanation:
The 4th term of the given geometric sequence is 54.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
The nth term of a GP is given as a[tex]r^{n-1}[/tex]
As per the given,
Common ratio r = 3
8th term = 4374
a(3)⁸⁻¹ = 4374
a = 2
The 4th term will be as, 2 x (3)⁴⁻¹ = 54
Hence "The 4th term of the given geometric sequence is 54".

Consider the triangle below.
Determine the angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle.
Answer:
angle 1= 30 degrees
angle 2= 120 degrees
angle 3= 30 degrees
Step-by-step explanation:
A triangle is equal to 180 degrees so first step is to subtract 120 to get the total of your two missing angles
180-120=60
and since your two missing angles are equal to each other you can divide by 2 and you get your two missing angles
60 / 2 = 30
