Step-by-step explanation:
[tex]3n^3-5n+n^2+8n^2-3n^3\\ \\ 9n^2-5n\\ \\ or\ n(9n-5)[/tex]
Answer:
[tex]9n^2 - 5n[/tex]
Step-by-step explanation:
[tex](3n^3 - 5n + n^2) - (-8n^2 + 3n^3)[/tex]
Lets open the brackets. Signs of all the terms in the bracket next to the minus sign will change.
[tex]=> 3n^3 - 5n + n^2 + 8n^2 - 3n^3[/tex]
Now lets add/substract all the like terms with each other.
[tex]=> 3n^3 - 3n^3 + n^2 + 8n^2 - 5n[/tex]
[tex]=> 9n^2 - 5n \: \: or \:\: n(9n - 5)[/tex]
Dana bought 12 pizzas for a Math Club party. Some were pepperoni pizzas that $11.00 each,
and the rest were mushroom pizzas that cost $9.50 each. She paid $124.50 for the pizzas. How
many pepperoni pizzas did she buy
Answer:
7 pepperoni pizzas
Step-by-step explanation:
First, you take the biggest number and subtract it by 9.5 until you get a number that can be divided into 11 which is 77.
Answer:
7 pepperoni pizzas
Step-by-step explanation:
Where p = # of pepperoni pizzas and m = # of mushroom pizzas
124.50 = 11p + 9.5m
Now you need to guess and check:
Use this equation: (124.5 - 11 * p) / 9.5 and replace p with whole numbers until you get a whole number as the output
I got p=7 and m=5
So she bought 7 pepperoni pizzas

In the figure below, MN | KL and are intersected by transversals ML and KN M 1551 What is the measure of , XMN?
130°
85°
55°
50°
Answer:
∠ XMN = 50°
Step-by-step explanation:
∠ XNM and ∠ XKL are alternate angles and are congruent, then
∠ XNM = 35°
The sum of the 3 angles in a triangle = 180° , so
∠ XMN = 180° - (95 + 35)° = 180° - 130° = 50°

Geometry Angle of elevation/depression
Answer:
m∠ACB = 49.88°
Step-by-step explanation:
From the figure attached,
Measure of wire AC attached to the top 'C' of the building BC = 340 m
Horizontal distance between the base 'B' of the building and point A = 260 m
Angle of depression = ∠ACB
By applying sine rule in the given triangle,
sin(∠ACB) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AB}{BC}[/tex]
= [tex]\frac{260}{340}[/tex]
m∠ACB = [tex]\text{sin}^{-1}(764706)[/tex]
= 49.88°
Someone help and please make sure it’s right
Answer:
20°
Step-by-step explanation:
Look at the attached photo.
∠a and ∠e are equal because they are vertical angles.
So, m∠a = 110°
Then, ∠f is an exterior angle to angles a and c. So,
m∠f = m∠a + m∠c
Substitute and solve.
130 = 110 + m∠c
m∠c = 20°
Then, ∠c and ∠d are vertical angles so they are equal.
m∠c = m∠d
m∠d = 20°
I hope this helps! Feel free to ask any questions!

Step-by-step explanation:
Johnson’s Hardware randomly selects 125 of its customers and questions them to determine their overall customer satisfaction rating. The poll indicates 100 were completely satisfied, 15 were satisfied, and 10 were not satisfied at all. What percent of customers were either satisfied or completely satisfied? About how many of the 5000 customers were not satisfied at all?
Answer:
a. 92%
b. 4425
Step-by-step explanation:
So there are 5000 customers in total, and 100 were completely satisfied, and 15 were satisfied and 10 weren't satisfied a bit. so 100+15 is 115 so 115 people in total were satisfied out of 125 because there were 125, and 115+10 is 125 anyways. So 115/125 is .92, and you can convert that into a percentage, 92% of the 250 customers were satisfied so then 250*5 is 5000, so then just multiply 115 by 5 as well. You get 575. So 575 were satisfied out of the 5000 customers and 5000-575 are the people not satisfied, so 4425.
probably wrong because it doesnt sound right but just try it

Brainliest??
Answer:
(-4 , 3)
Step-by-step explanation:
The y-axis is the vertical axis/line out of the two perpendicular lines.
Vertical line/axis (y-axis)= │
Horizontal line/axis (x-axis)= ___
When you reflect Point A, it will be reflected across the vertical line (y-axis). This means that the point will be on the left side in Quadrant II (- , +).
A store sells 24 greeting cards for $12. Select the three unit rates that describe this sale. CLEAR CHECK 2 cards per dollar $0.50 per card 10 cards per $5 $6 per dozen cards
Answer:
2 cards per dollar
$0.50 per card
$6 per dozen cards
Step-by-step explanation:
The unit rate of greeting if a store sells 24 greeting cards for $12 is $0.5, so option $0.50 per card is correct.
What is Unit rate?
Unit rate means the amount of rate for the unit quantity of some things, for example, if you buy 1 kg apple for $2 then the unit rate of apple is $2.
Given:
The selling price of 24 greetings =$12,
The unit rate, of a greeting, is = The selling price of 24 greetings / no of greetings
The unit rate = 12 / 24
The unit rate = $0.5
Therefore, the unit rate of greeting if a store sells 24 greeting cards for $12 is $0.5.
