Answer:
2.20 per 1000 so it's gonna be $2.20/1000 per 1. So 4500 take $2.20/1000*4500=...
Step-by-step explanation:
Answer:
$11.00
Step-by-step explanation:
1000 x 4 = 4000
4000 < 4500
1000 x 5 = 5000
5000 > 4500
2.20 x 5 = 11

khan academny questions are confusing when you're doing math in the middle of the night
Step-by-step explanation:
Answer of your question is 800Expand.
Your answer should be a polynomial in standard form.
Answer:
-p^4 + 4p^3 - 5p^2 + 8p - 6
Step-by-step explanation:
Distribute the -p^2 to the p^2 and the 2. Then distribute the 4p to the p^2 and the 2. Then distribute the -3 to the p^2 and the 2.
When we expand:
-p^4 - 2p^2
+ 4p^3 + 8p
-3p^2 - 6
Group, ordering from highest to lowest "degree" (exponent).
-p^4 + 4p^3 - 2p^2 - 3p^2 + 8p - 6
Combine like terms.
-p^4 + 4p^3 - 5p^2 + 8p - 6
Go Which operation would be completed second in the following expression? 7² -3+9+8 dividend by two
Choices:
Subtract
Multiply
divide
Simplify the exponet
Answer:
Divide
Step-by-step explanation:
Using PEMDAS, the first would be parenthesis, but there are none, so we do not use P. Next is E which is exponents, which would be the first thing completed. Then is M and D which is multiplication and division. The division is used which is "dividend by two" as it's the second thing completed.
Hope this helped.
What is the value of a?
Answer:
90
Step-by-step explanation:
Use angle-arc relation,
For a and 45, Inscribed angle's relation can be utilized
Inscribed angle=Half the arc
45=1/2a
Therefore, a=90

Answer:
Step-by-step explanation:
Use Pythagorus to find the length of the unmarked length
c^2 = a^2 + b^2
a = 5
b = 17 -10 = 7
c = ?
c^2 = 5^2 + 7^2
c^2 = 25 + 49
c = sqrt(74)
c =8.602
P = 5 + 10 + 17 + 8.602
P = 40.602

Dilbert invests a total of $26,000 in two accounts paying 14% and 2% annual interest, respectively. How much was invested in each account if, after one year, the total interest was $2,560.00
Answer:
$17,000 at 14% and $9,000 at 2%
Step-by-step explanation:
Let x = amount invested at 14%.
Let y = amount invested at 2%.
x + y = 26000
0.14x + 0.02y = 2560
-0.02x - 0.02y = -520
(+) 0.14x + 0.02y = 2560
-------------------------------------
0.12x = 2040
x = 17,000
x + y = 26000
17000 + y = 26000
y = 9000
Answer: $17,000 at 14% and $9,000 at 2%
1.Find x,y and z in the figure. 2. find the x and y in the figure

[tex]\\ \sf\longmapsto z=180-30[/tex]
[tex]\\ \sf\longmapsto z=150[/tex]
Answer:
Figure 1Straight angle is 180°:
2x + 90° + x = 180° ⇒ 3x = 90° ⇒ x = 30°Alternate interior angles are congruent:
2y = x ⇒ 2y = 30° ⇒ y = 15°Consecutive interior angles are supplementary:
x + z = 180° ⇒ z = 180° - 30° ⇒ z = 150°Figure 2Alternate interior angles:
3x = 5x - 20° ⇒ 2x = 20° ⇒ x = 10°Sum of interior angles of a triangle:
2y + 4y + 5x - 20 = 180° ⇒ 6y + 5*10° = 200° ⇒ 6y = 150° ⇒ y = 25°TO BE ANSERED ASAP

Step-by-step explanation:
4x^3+2
4*(-1)^3+2
4*(-1)+2
-4+2
-2
Answer: -2
Step-by-step explanation:
Replacing x for -1 would make the equation [tex]4(-1^3)+2[/tex]. Knowing PEMDAS, we know that the parentheses goes first. [tex]-1^3[/tex] means that we need to multiply -1 by itself 3 times ([tex]-1*-1*-1[/tex], * equals "times"). [tex]-1*-1=1[/tex] so [tex]1*-1=-1[/tex]. Now our equation is [tex]4(-1)+2[/tex]. [tex]4*-1=-1[/tex] and -4 + 2 = -2. Hope this explanation helps :)

In order to study the shoe sizes of people in his town, Billy samples the population by dividing the residents by age and randomly selecting a proportionate number of residents from each age group. Which type of sampling is used
Answer:
Stratified sampling
Step-by-step explanation:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
Divided by groups(according to age)
A certain amount of each group is sampled.
Thus, stratified sampling is used.

Answer: 1/3
Step-by-step explanation:
On side of the smaller quadrilateral is 8, the same side on the larger one is 24. 8 times 3 is 24. So the scale factor from the smaller to the larger is 1/3.
Answer:
1/3
Step-by-step explanation:
similar means all sides are proportinal, in this case one side is 3x bigger in the 2nd figure, so the same must be true of the other fig.
Find the perimeter of a quadrilateral with vertices at C (−2, 1), D (2, 4), E (5, 0), and F (1, −3). Round your answer to the nearest hundredth when necessary.
Answer: the perimeter is 20
Step-by-step explanation:
Distance between C and D
Sqrt (-2-1)^2 + (1- -3)^2=
Sqrt -3^2 + 4^2=
Sqrt 25 = 5
Between D and E
Sqrt(5-2)^2+(0-4)^2=
Sqrt 25 = 5
Between E and F
Sqrt(1-5)^2+(-3-0)^2=
Sqrt 25=5
It is a square
The value of the perimeter of a quadrilateral is, 20 units
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
We have to given that;
Vertices are,
C (- 2, 1), D (2, 4), E (5, 0), and F (1, - 3).
Since, The distance between two points (x₁ , y₁) and (x₂, y₂) is,
⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²
Hence, We get;
CD = √(- 2 - 2)² + (1 - 4)²
CD = √16 + 9
CD = √25
CD = 5
DE = √( 2 - 5)² + (4 - 0)²
DE = √9 + 16
DE = √25
DE = 5
EF = √(5 - 1)² + (0 + 3)²
EF = √16 + 9
EF = √25
EF = 5
FC = √(- 2 - 1)² + (1 + 3)²
FC = √9 + 16
FC = 5
Thus, The value of the perimeter of a quadrilateral is,
CD + DE + EF + FC
5 + 5 + 5 + 5
20 units
