Answer:
Consider: (a+b)(a-b)=a^2-ab+ab-b^2=a^2-b^2. This is a binomial. Hence, it is not always true that the product of two binomials is a trinomial.
Step-by-step explanation:
Determine the type of triangle that is drawn below.
Answer:
Step-by-step explanation:
Since each angle is different it is scalene. Since all angles are less than 90 degrees it is acute.
So this is a Scalene Acute triangle.
Answer: Scalene Acute
Step-by-step explanation:
An acute triangle has all three angles less than 90 and a scalene triangle has no equal sides.
Distribute (2m-5m)(-5)
First Method (Distributive Property)
(2m - 5m) (-5)
Rearrange the equation to make it easier.
(-5) (2m - 5m)
In distributive property, it's all about multiplying. The -5 goes to the 2m and the 5m. Like this: (-5 • 2m) - (-5 • 5m).
-10m + 25m
15m
Second Method
(2m - 5m) (-5)
Since 2m and 5m have the same variable, we can subtract them.
(-3m) (-5)
Multiply.
15m
15m is your answer. I hope this helps!
Which of the following functions has a rate of change that stays the same? (1 point)
O y = x2 - 5x -14
O y = 19x - 10

find NM
Answer:
NM = 15
Step-by-step explanation:
Given a secant and a tangent from an external point to the circle, then
The square of the measure of the tangent is equal to the product of the secant's external part and the entire secant, that is
(x + 3)² = (x - 3)(x - 3 + 16)
(x + 3)² = (x - 3)(x + 13) ← expand both sides using FOIL
x² + 6x + 9 = x² + 10x - 39 ( subtract x² + 10x from both sides )
- 4x + 9 = - 39 ( subtract 9 from both sides )
- 4x = - 48 ( divide both sides by - 4 )
x = 12
Then
NM = x + 3 = 12 + 3 = 15

62\100
simplest form
45\100
simplest form
Answer:
62/100= 31/50
45/100= 9/20
Step-by-step explanation:
Divide 62 and 100 by two to simplify
Divide 45 and 100 by 5 to simplify
Answer:
62/100 = 31/50
45/100 = 9/20
Step-by-step explanation:
62 and 100 have a greatest common factor of 2. We can use this to break the fraction 62/100 apart:
[tex]\dfrac{62}{100}=\dfrac{2\times31}{2\times50}=\dfrac{2}{2}\times\dfrac{31}{50}=\dfrac{31}{50}[/tex]
We can do the same to simplify 45/100. The greatest common factor of 45 and 100 is 5, so following the same process:
[tex]\dfrac{45}{100}=\dfrac{5\times9}{5\times20}=\dfrac{5}{5}\times\dfrac{9}{20}=\dfrac{9}{20}[/tex]

A scientist is studying bacteria in a dish and discovered they grow and can 3 be tracked using the formula: 5*(1.50)^x +10, where x represents every hour. How many bacteria will there be after 9 hours? (Round Your Answer To The Nearest Whole Number)
A) 38
B) 48
C) 192
D) 202
Answer:
D
Step-by-step explanation:
if x= number of hours replace the x by 9
so you have 5×(1.50)^9+10=
5×(192.21)+10 = 202.21 so 202 will be nearest whole number
Sarah bought 18 boxes of 65 pens at $12 a box. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. Find her total profit.
Answer:
$108
Step-by-step explanation:
The computation of the total profit is shown below:
Given that
1 box = $12
18 boxes = 12×18 = $216
So
Total = 18×65 = 1170 pens
Now Cost price, Cp = $216
Also,
3 = $1
So,
= 378 ÷ 3
= $126
Now
= 1170-378
= 792 pens remaining
4 = $1
So,
792
= 792 ÷ 4
= $198
Now
Total selling price, sp = 126+198 = $324
So finally
Profit = Sp - Cp
= $324 - $216
= $108
The volume of a cereal box is 264 in3 . If it has a width equal to 3 inches and length of 8 inches, what is the height?
Answer:
11 inches
Step-by-step explanation:
Volume of a box is:
[tex]l * w * h[/tex]
[tex]8 * 3 * h = 264\\\\24*h=264\\\\\frac{24*h=264}{24} \\\\\boxed{h=11}[/tex]
The height is 11 inches.
Hope this helps.
Volume of the box = LWH.
Let V = 264
264 = (8)(3)(H)
264 = 24H
264 ÷ 24 = H
11 = H
The height of the box is 11 inches.

A floor 3.2m long and 2.8 m wide is to be covered with square shaped tiles of length 10cm. Find the coast of flooring if the coast tiles is Rs 150 per 100 tile.
Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344

Find the surface area of the cube show below
2/3
Answer:
Step-by-step explanation:
there are 6 sides on a cube
surface area = 6 times the area of one face of the cube
= 6 times ( a side times another side) note all sides are equal
= 6(side)² is a side equal to 2/3 ?? if it is ....
= 6(2/3)²
= 6(2/3)(2/3) one of the 3s divide into 6 twice
= 2(2)(2/3)
= 2³ / 3
= 2x2x2 / 3
= 8 /3
= 2 and 2/3 units²

Directions: For a spinning amusement park ride, the velocity v in meters per second of a car moving around a curve with a radius r meters is given by the formula v= √ar, where a is the car’s acceleration in m/s2.
1. For safety reasons, a ride has a minimum acceleration of 39.2 m/s2. If the cars on the ride have a velocity of 14 m/s what is the smallest radius that any curve on the ride may have?
2. What is the acceleration of a car moving at 8m/s around a curve with a radius of 2.5m?
Answer:
1. r = 5 m 2. a = 25.6 m/s²
Step-by-step explanation:
The relation between the velocity, the radius of path and the acceleration on the circular path is given by :
[tex]a=\dfrac{v^2}{r}[/tex]
1. Acceleration, a = 39.2 m/s²
Velocity of the car, v = 14 m/s
The radius of the path can be calculated using the above formula i.e.
[tex]r=\dfrac{v^2}{a}\\\\r=\dfrac{(14)^2}{39.2}\\\\r=5\ m[/tex]
2. Velocity of the car, v = 8 m/s
The radius of the path, r = 2.5 m
The acceleration of the car is given by :
[tex]a=\dfrac{8^2}{2.5}\\\\a=25.6\ m/s^2[/tex]
Hence, this is the required solution.
