Step-by-step explanation:
The given shape is a pentagon, an irregular polygon, and also convex.
What is a polygon?A Polygon is considered to be Concave if its diagonal can lie outside the Polygon as well.
A polygon is considered to be Convex if all of its diagonals lie within it.
A polygon is considered to be regular if it is convex and has equal sides and angles.
If all of the angles and sides of a polygon are not equal, it is said to be irregular.
Here,
The given shape has five sides, which means this is a pentagon.
The given shape has unequal sides, which means this is an irregular pentagon.
The given shape has it's all its diagonals lying inside, which means this is a convex pentagon.
Thus, the given shape is a pentagon, an irregular polygon, and also convex.

The density of platinum is approximately 21 grams per cmº.
Which of the items cannot be platinum?
You must show your working.
Answers
Answer: Multiply the density with the volume. You get 2418.2 grams or 2.4182 kilograms
Step-by-step explanation:
Answer:
Item B
Step-by-step explanation:
A:
density = mas/volume = 42 g / 2 cm^3 = 21 g/cm^3
This may be platinum.
B.
density = mass/volume = 87.5 g / 5 cm^3 = 17.5 g/cm^3
This cannot be pure platinum.
C.
density = mass/volume = 147 g / 7 cm^3 = 21 g/cm^3
This may be platinum.

Abag of peanuts is 5 times as heavy as a bag of sunflower seeds. The bag of peanuts
also weights 920 grams more than the bag of sunflower seeds. What is the total weight
in grams for the bag of peanuts and the bag of sunflower seeds?
Answers
Answer:
5s=p
s+920=p
5s=s+920
*subtract s from both sides*
4s=920
*divide 4 from both sides*
s=230
230*5=1150
The bag of sunflower seeds weighs 230 grams and the bag of peanuts weighs 1150 grams.
9514 1404 393
Answer:
1380 grams
Step-by-step explanation:
The ratio of weights is ...
peanuts : sunflower seeds = 5 : 1
Then the difference in weights is ...
5 - 1 = 4 . . . . ratio units
The sum of weights is ...
5 + 1 = 6 . . . . ratio units
That is the sum of the weights related to the difference of weights is ...
sum : difference = 6 : 4 = 3 : 2
So, the total weight of the two bags is 3/2 times the difference in their weights:
total weight = (3/2)(920 grams) = 1380 grams

Della went to the market to buy 4.5 pounds of sliced fruit in a container. She paid with a $20 bill and a $5 and received $4.67 as change. She paid $1.62 in taxes and for the fruit. What was the cost for one pound of sliced fruit before taxes
Answers
Answer:
the cost for one pound before taxes is $4.52
Step-by-step explanation:
The computation of the cost for one pound before taxes is shown below:
= Paid a bill + amount - change amount
= $20 + 5 - $4.67
= $20.33
Now the cost of one pound would be
= Total amount ÷ number of pounds purchased
= $20.33 ÷ 4.5 pounds
= $4.52
Hence, the cost for one pound before taxes is $4.52

Cathy would like to have accumulated $25,000 on her IRA account in 5 years. The return is 3.1%. How much should Cathy deposit in her account annually?
$1,329.94
$2,711.73
$4,699.46
$5,000.00
Answers
Answer:
Annual deposit= $4,699.46
Step-by-step explanation:
Giving the following information:
Future value (FV)= $25,000
Number of periods (n)= 5 years
Interest rate (i)= 3.1% = 0.031
To calculate the annual deposit, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (25,000*0.031) / [(1.031^5) - 1]
A= $4,699.46
A pair of angles is supplementary if the sum of their measures is 180 degrees. A pair of angels is complementary if the sum of their measures 90 degrees. the supplement of a given angel is 10 degrees more than twice its complement. Let 90-x equal the degree measure of its complement and 180-x equal the degree measure of its supplement. Write and solve an equation to find the measure of the given angel.
Answers
Answer:
The measure of the complement =
= 80°
The measure of the supplement=
= 170°
Step-by-step explanation:
Let
90-x equal the degree measure of its complement
180-x equal the degree measure of its supplement.
We are told in the question that: the supplement of a given angle is 10 degrees more than twice its complement.
Hence, the Equation is;
(180 - x) = 10° + 2(90 - x)
180 - x = 10 + 180 - 2x
Collect like terms
-x + 2x = 10 + 180 - 180
x = 10°
Hence,
The measure of the complement =
90 - x
= 90 - 10
= 80°
The measure of the supplement=
180 - x
= 180 - 10
= 170°

The population of bears in a national forest is changing according to the function N(t)=850(1.04)t , where t is the time in years, and N(t) is the number of bears. Which statement explains how the bear population is changing?
Answers
Answer:
The statement is that the population increases at a rate of 4% per year
Step-by-step explanation:
The function is given as;
N(t) = 850(1.04)^t
The general equation form for a representation as this is;
P = I(1 + r)^t
Where I is the initial value and P is the present value
r is the rate of increase
t is the time
Thus, we have that;
1 + r = 1.04
r = 1.04-1
r = 0.04
0.04 is same as 4/100 which is same as 4%
So the statement about how the population of bear is changing is that the population increases at a rate of 4% each year

Solve for x:16^(4x-3)=8^(2x+4)
Answers
Answer:
x = 2.4
Step-by-step explanation:
16^(4x - 3) = 8 ^ (2x + 4)
16 = 2^4
8 = 2^3
2 ^ 4*(4x - 3) = 2^3(2x + 4)
Since the bases are the same, you can equate the powers
4(4x - 3) + 3*(2x + 4) Remove the brackets.
16x - 12 = 6x + 12 Subtract 6x from both sides
16x - 6x - 12 = 12 Combine the terms on the left
10x - 12 = 12 Add 12 to both sides
10x = 24 Divide by 10
x = 2.4
