simplify this expression 4^5/4^3
Answer:
It is 4 squared
Step-by-step explanation:
When dividing exponents it’s almost like subtraction so 4^5/4^3 is 4^2

A six sided die is rolled then a quadrilateral is chosen at random parallelogram ,rhombus, rectangle square and trapezoid. What is the probability of getting five quadrilateral with four congruent sides?
Answer:
1. Square
2. Rhombus
I hope I helped, if not please let me know and I will correct my answer.
Happy new year, good luck with your future studies.
Step-by-step explanation:
The probability of getting five quadrilateral with four congruent sides is,
⇒ 1 / 3
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
A six sided die is rolled then a quadrilateral is chosen at random parallelogram ,rhombus, rectangle, square and trapezoid.
Hence, Total number of outcomes = 6
And, We know that;
Square and Rhombus have four congruent sides.
Hence, Number of possible outcomes = 2
Thus, The probability of getting five quadrilateral with four congruent sides is,
⇒ 2 / 6
⇒ 1 / 3

Answer:
x = 3(y -1)
Step-by-step explanation:
In this, and any, "solve for ..." situation, you want to first take a look at where the variable of interest is in the equation, and what has been done to it.
Here, x is on the right side (only). It has these operations done to it:
multiplied by 1/31 added to the productYou solve for x by undoing these operations, in reverse order. As always, with any equation, you do the same thing to both sides of the equation.
__
First, we will undo "add 1". We do that by adding the opposite of 1.
y -1 = 1/3x +1 -1 . . . . . -1 added (to both sides)
y -1 = 1/3x . . . . . . . . . simplify
To undo the "multiply by 1/3", we can multiply by the "multiplicative inverse" (reciprocal) of 1/3. That is, we want to multiply by 3.
3(y -1) = 3(1/3x) . . . . . multiply (both sides) by 3
3(y -1) = x . . . . . . . . . simplify
We can leave it like this.
x = 3(y -1)
Or, we can eliminate parentheses using the distributive property .
x = 3y -3
These are completely equivalent equations with x as the subject.

3x + 1 = 10
Show work
Answer:
x = 3
Step-by-step explanation:
3x + 1 = 10
subtract 1 from both sides of the equation
3x + 1 - 1 = 10 - 1
3x = 10 - 1
3x = 9
divide both sides of the equation by 3
3x/3 = 9/3
x = 9/3
x = 3
Answer:
X=3
Step-by-step explanation:
3x+1=10 -> switch 1 3x = 10 - 1
3x = 9
9/3 = 3

A police officer recorded the speeds of 100 cars in a 50-mile-per-hour zone. The results are in the box plot shown. How many cars were going between 40 and 48 miles per hour? I know the answer but I need to know how to do it
Answer: 25 cars
Step-by-step explanation:
This is a box plot and it is a useful graph for showing the minimum, maximum, median and quartile values of a data distribution.
The box you see in the middle is the Interquartile range. In other words, the first line on the box is Q1 and the line at the end of the box is Q3.
The line in the middle of the box is the median or Q2.
The distance between Q1 and the median is 25%.
The number of cars between 40 and 48 miles per hour is therefore 25% of the total.
= 100 * 25%
= 25 cars
Answer:
25 cars

The first lap of an auto race is 2,500 meters. This is 10% of the total race distance. What is the total race distance?
Answer:
25,000
Step-by-step explanation:
.10(x) = 2,500
X = 2,500/(.10)
X=25,000
The length of the total race track is 25000 meters.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Let, 'x' be the total distance.
Therefore, From the given information 10% x is 2500 meters, This can be numerically expressed as,
(10/100)×x = 2500.
0.1x = 2500.
x = 25000.

1_____ × 10-3 is 2,000 times greater than 1.9 × 10-6. It is also
2_____ times greater than 9.5 × 10-4.
Answer:
Well, 1 is 3.8 The second one is 40,
Step-by-step explanation:
I believe 1 is 3.8, b/c 1.9*2 is 3.8, and the difference between exponents makes 3 zeros, so 2000.
The second one is 40, I confirmed this by doing .0001 to replicate 10 to the negative 4th power
By doing 9.5*.0001*40, I got the 0.038 from 1
Answer:
3.8 × 10-3 is 2,000 times greater than 1.9 × 10-6. It is also 4 times greater than 9.5 x 10-4.
Step-by-step explanation:
I started by doing 0.0000019 x 2000 and got 0.0038. If you move the decimal point 4 over you get 3.8.
EVERYONE ELSE IS WRONG!!! I got this correct on the test after retaking it, the second one is NOT 40 it is 4.
Alexander invested $320 in an account paying an interest rate of 1.5% compounded annually. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 18 years?
Answer:
$406.40
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1.5%/100 = 0.015 per year.
Solving our equation:
A = 320(1 + (0.015 × 18)) = 406.4
A = $406.40

Answer:
ASA
Step-by-step explanation:
If 2 angles and the included side of one triangle are congruent to 2 angles and the included side of the other triangle, then the triangles are congruent.
The included side is the side between the vertices of the 2 triangles.
Here
∠ S = ∠ W ( 1 angle )
∠ R = ∠ X ( 2 angles )
RS = XW ( side between the 2 angles )
Thus the 2 triangles are congruent by the ASA postulate
