what is 6(-5n + 7) simplified?
Answer:
-30n+42
Step-by-step explanation:
You have to use distributive property.
Multiply 6 with -5n which is -30n. Then, Multiply 6 with 7 which is 42. Since, 5n is negative the product is also negative, and since 7 is positive the product is positive. Therefore you will get, -30n+42.
I hope this helps!

The simplified form of 6(-5n + 7) is -30n + 42.
To simplify the expression 6(-5n + 7), we apply the distributive property. The distributive property states that when we multiply a number outside the parentheses by an expression inside the parentheses, we must multiply it by each term inside the parentheses.
In this case, we have 6 multiplied by the expression (-5n + 7).
Multiplying 6 by -5n gives us -30n, and multiplying 6 by 7 gives us 42.
So, combining these results, we get -30n + 42.
This simplified expression, -30n + 42, cannot be further simplified because there are no like terms to combine.
Therefore, 6(-5n + 7) simplifies to -30n + 42.

convert the rectangular coordinates (3,4) into polar coordinates
Answer:
(5,53°) or (5,53.13010235°) if you want an exact value.
Step-by-step explanation:
Polar coordinate is in [tex]\displaystyle{(r,\theta)}[/tex] form and rectangular coordinate is in [tex]\displaystyle{(x,y)}[/tex] form.
To convert from rectangular coordinate to polar coordinate, you’ll have to know that:
[tex]\displaystyle{x=r\cos \theta}\\\displaystyle{y=r\sin \theta}[/tex]
Above is crucial when it comes to converting from rectangular coordinate to polar coordinate, or other way around. The thing is to convert from rectangular to polar, you’ll also have to know radius too which you can find by:
[tex]\displaystyle{r=\sqrt{x^2+y^2}}[/tex]
We know that x = 3 and y = 4, substitute in the formula:
[tex]\displaystyle{r=\sqrt{3^2+4^2}}\\\\\displaystyle{r=\sqrt{9+16}}\\\\\displaystyle{r=\sqrt{25}}\\\\\displaystyle{r=5}[/tex]
We know that radius is 5. We will have to find the theta next, first substitute in the conversion:
[tex]\displaystyle{3=5\cos \theta}\\\displaystyle{4=5\sin \theta}[/tex]
Since this can generally be found through calculator as it’s not a part of special triangle - can be found using hand method - The approximation of both theta’s values are 53°.
Hence, the polar coordinate is (5,53°) or (5,53.13010235°) if you want an exact value.

What do you do with negative exponent?
Answer:
this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents. Only move the negative exponents.
¯\_(ツ)_/¯
Answer:
Negative exponents are a way of writing powers of fractions or decimals without using a fraction or decimal. You use negative exponents as a way to combine expressions with the same base, whether the different factors are in the numerator or denominator. It’s a way to change division problems into multiplication problems.
Step-by-step explanation:
A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa.
Each side of a pentagon is 20 inches longer than the previous side. What is the length of the shortest side is the perimeter is 401 inches?
Answer:
40.2
Step-by-step explanation:
Side 1= x
Side 2= x+20
Side 3= x+40
Side 4= x+60
Side 5= x+80
Total perimeter= 401
x+x+20+x+40+x+60+x+80= 401
Simplify it...
5x=201
x= 40.2
This is the answer= 40.2
Please award me brainliest!
Thanks!
The length of the shortest side of the pentagon would be:
40.2
Find the lengthGiven that,
Every side of a pentagon is longer by 20 inches.
No. of sides in pentagon = 5
So,
Ist side of the pentagon [tex]= x[/tex]
IInd Side of the pentagon [tex]= x + 20[/tex]
IIIrd Side of the pentagon [tex]= x + 40[/tex]
IVth Side of the pentagon [tex]= x + 60[/tex]
Vth Side of the pentagon [tex]= x + 80[/tex]
We know that,
Perimeter = Sum of all the sides
Since the perimeter is 401 inches, the side can be determined through:
[tex]401 = x+x+20+x+40+x+60+x+80[/tex]
⇒ [tex]401 = 5x + 200[/tex]
⇒ [tex]401 - 200 = 5x[/tex]
⇒ [tex]201/5 = x[/tex]
∵ [tex]x = 40.2[/tex]
Thus, 40.2 is the correct answer.

Starting at a fixed time, each car entering an intersection is observed to see whether it turns left (L), right (R), or goes straight ahead (A). The experiment terminates as soon as a car is observed to turn left. Let X = the number of cars observed. What are possible X values? List five different outcomes and their associated y values.
Answer:
Outcomes are { L, RL, AL, RAL, ARL }
Associated X values are { 1, 2, 2, 3, 3 }
Step-by-step explanation:
As given,
left = (L),
right = (R)
goes straight ahead = (A)
Now,
The Sample space become = { L, RL, AL, RAL, ARL }
In L -
Number of cars = 1
In RL-
Number of cars = 2
In AL-
Number of cars = 2
In RAL-
Number of cars = 3
In ARL-
Number of cars = 3
To build a deck, Roberto needs to buy 180 screws (s), 9 posts (p), and 36 pieces of 1" by 6" lumber (l). He already had the rest of the materials for the deck that he needs. An expression that represents his purchases is shown below:
180s + 9p + 36l
Part A:
Factor the expression that represents Roberto's purchases.
Part B:
The costs of buying the deck materials are shown in the chart below:
Material Cost
100 screw container $6.99
1 post $16.40
Set of 10 pieces of lumber $88.20
What materials does Roberto need to buy?
Part C:
What is the total cost to buy the deck materials (excluding tax)?
The total cost of materials can be found from a list of materials based on the market unit rate.
The correct responses are;
Part A: The factored expression is; 9 × (20·s + p + 4·l)Part B: The materials to be bought are; 2 cartons of screws, 9 pieces of posts, and 4 sets of 10 pieces of lumber.Part C: The total cost of materials is $514.38.Reasons:
Part A: The given expression representing the purchase is presented as follows;
Purchases = 180·s + 9·p + 36·l
Where;
s = Screws
P = Posts
l = Lumber
The factored expression is found as follows;
Purchases = 180·s + 9·p + 36·l = 9 × 20·s + 9·p + 9 × 4·l, which gives;
180·s + 9·p + 36·l = 9 × (20·s + p + 4·l)
The factored expression is; 9 × (20·s + p + 4·l)
Part B: The costs are;
100 screws = $6.99
1 posts = $16.40
10 pieces of lumber = $88.20
The materials Roberto need to buy are;
180 screws, which can be obtained by buying 2 cartons of screws.
9 posts, which is obtained by buying 9 pieces of posts.
36 lumber which can be obtained by buying 4 × 10 pieces = 40 pieces of lumber.
Therefore, the, material Roberto needs to buy are;
2 cartons of screws
9 pieces of posts
40 pieces of lumber
Part C: The total cost of the materials are therefore;
2 cartons of screws × $6.99 per carton = $13.98
9 pieces of posts × $16.40 per piece = $147.6
4 Sets of 10 pieces of lumber × $88.20 per set = $352.8
The total cost = $13.98 + $147.6 + $352.8 = $514.38

What is an equation of the line that passes through the point (-5 7) and is parallel to the line x-5y=15
Answer:
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
Slope = m & y-intercept = b
x - 5y = 15
-5y = -x + 15
y = [tex]\frac{-1}{-5}x + \frac{15}{-5}\\\\[/tex]
[tex]y = \frac{1}{5}x - 3[/tex]
so, slope = 1/5 ; (-5 , 7)
y -y1 = m(x -x1)
[tex]y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8[/tex]

When you multiply a given fraction by a factor greater than 1, the product will (always, sometimes, never) be less than the given fraction
9514 1404 393
Answer:
sometimes
Step-by-step explanation:
For positive numbers, multiplying by a factor greater than 1 increases their value:
(1/2) × 2 = 1 > 1/2
For negative numbers, multiplying by a factor greater than 1 decreases their value:
(-1//2) × 2 = -1 < -1/2
So, "sometimes" the product will be less than the given fraction.
