Step-by-step explanation:
The set of whole numbers of whole numbers is closed under addition and multiplication when because you add or multiple any whole numbers, the result is always whole number.EXAMPLE, closure property, 5 and 6 is whole numbers and multiplication of 5 and 6 is 30. Also, 30 is a whole number.Answer:
yup. whole numbers begin from zero
so any whole number times any whole number will give me a whole number
eg 0×4=0
67×98765=6617255
etc
note. a negative number isn't a whole number
Steve has a piece of fishing line measuring 6 yards. How many 1-inch strips can be cut from the line? Answers:a 6 strips b 18 strips c 36 strips d 72 strips
Answer:

1 yard = 36 inches
so 6 yards would equal : 6 x 36 = 216 inches
Thus 216 strips would be cut
Step-by-step explanation:
D) 72 strips
Two ships are near a buoy in the open ocean. One ship is 20 km due north of the buoy, and the other ship is 13.5 km due east of the buoy.
Round the answer to the nearest tenth.
Answer:
24 km is your answer
Step-by-step explanation:
Let x be the distance between the two ships.
Hypotenuse side = x km
Adjacent side = 13.5 km
Perpendicular side = 20 km
by using Pythagoras theorem:
x²= 13.5²+ 20²=582.25
x=√ 582.25
х =24.129857024 km
Therefore, the distance between two ships to the nearest tenth place is, 24.1 km

Evaluate 32 + (5 − 2) ⋅ 4 − 6 over 3. (1 point)
3 squared.
Explanation: Because it's correct.
Answer:
i did 3^2 and the answer would be 19 for that.
Step-by-step explanation:
3^2 + (5 − 2) ⋅ 4 − 6 over 3
9 + 3 ⋅ 4 - 6 over 3
9 + 12 - 6 over 3
21 - 6 over 3 (which equals 2)
is 19 :)
The following are the ages (years) of 5 people in a room:
17, 21, 15, 15, 25
A person enters the room.
The mean age of the 6 people is now 25.
What is the age of the person who entered the room?
Answer:
57 years
Step-by-step explanation:
total=25*6=150
17+21+15+15+25+x=150
93+x=150
x=150-93
x=57
Answer:
age=57
Step-by-step explanation:
ages=17 21 15 15 25 ?
17+21+15+15+25=93(old mean)
17+21+15+15+25+?=25(new mean)
25(new mean)*6(number of numbers)=150
?=150-93=57
= 57
What is the area of the real store in square inches? What is the area of the real store in square feet? What are the dimensions (length and width) of the store in feet? Is it a big store or a small one? PLEASE HELPP!!
Answer:
The dimensions of the real store are 80 times bigger as per scale:
1.875 in * 80 = 150 in = 150/12 ft = 12.5 ft2.25 in * 80 = 180 in = 180/12 ft = 15 ftThe area of the real store:
150 in * 180 in = 27000 in²12.5 ft * 15 ft = 187.5 ft²find the missing angle measure of the following figure
Answer:
Step-by-step explanation:
By triangle sum theorem,
73°+ 39° + m∠1 = 180°
m∠1 = 180° - 102°
m∠1 = 78°
Since, m∠1 = m∠2 [Vertically opposite angles]
m∠2 = 78°
Sum of interior angles of a polygon = (n - 2)×180°
Where n = number of sides of the polygon
Sum of the interior angles of a quadrilateral = (4 - 2)×180°
= 360°
Therefore, 77° + m∠3 + 90° + m∠2 = 360°
77° + m∠3 + 90° + 78° = 360°
m∠3 = 360° - 245°
m∠3 = 115°

Answer:
Yes
Step-by-step explanation:
Being proportional means that if you divide the Y value by the X number for each ordered pair, they all equal the same number
For this case, this is proportional because you need to multiply by 6 to get the Y value.

In Mr. Jegou's neighborhood 35% of the houses are blue. Write the
percent that do not live in blue houses as a decimal and a fraction in simplest form
Answer:
Fraction: 3/20
Decimal: 0.35
Step-by-step explanation:
a) 100% - 35% = 65
So, 65% of the houses are NOT blue.
..............................................
Fraction: 3/20
Decimal: 0.35
Answer:
65/100 or 0.65
Step-by-step explanation:
To answer this problem all you have to do is subtract 35%.If an A+ is an 100 percent,Then subtract 100 and 35 giving you 65 percent.
But if you do not know how to turn a fraction or decimal,then i will show you.every time you have a number in the tens place,add a zero and the add the decimal and finally add 65 which making look like this:0.65.
Fraction is easy to do as long as you do a number out of 100,like this:65/100.
simple :)
Just please help me, im trying to cram multiple things at once (house is crazy) and I just cant seem to concentrate and understand these.

Step-by-step explanation:
here is how you find the answer
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
now apply the above rules to the given triangle
where we are given the angle of 30° and the Adj side of 27
y is the Hyp of this triangle and x is the Opp side of this triangle, now plug in the given values as follows
so use CAH Cos(30) = 27 / Hyp
Hyp = 27 / Cos(30)
Hyp = 27 / ([tex]\sqrt{3}[/tex] / 2)
Hyp = 27 * 2 / [tex]\sqrt{3}[/tex]
Hyp = 54 / [tex]\sqrt{3}[/tex]
y = 54 / [tex]\sqrt{3}[/tex]
use SOH, since we know the exact value for the Hyp from above
Sin(30) = Opp / ( 54 / [tex]\sqrt{3}[/tex] )
Sin(30) * 54 / [tex]\sqrt{3}[/tex] = Opp
1/2 * 54 / [tex]\sqrt{3}[/tex] = Opp
27 / [tex]\sqrt{3}[/tex] = Opp
x = 27 / [tex]\sqrt{3}[/tex]
:)
Which rule describes the x-coordinates in the translation below?.
x + 0
x + 6
x – 6
x + 2
Answer:
A) x + 0
Step-by-step explanation:
In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)
In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)
Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.
Therefore, the rule for x-coordinates = x + 0
Answer: A) x + 0

A cereal box has a surface area of 280 square inches. What is the surface are of a similar box that is larger by a scale factor of 1.4 ?
Answer: 548.8 square inches
Step-by-step explanation:
From the question, we are informed that a cereal box has a surface area of 280 square inches.
The surface area of a similar box that is larger by a scale factor of 1.4 will be gotten by multiplying 280 by the scale factor's square. This will be:
= 280 × (1.4)²
= 280 × 1.96
= 548.8 square inches

An item costs $420 before tax, and the sales tax is $25.20 . Find the sales tax rate. Write your answer as a percentage.
Answer:
6%
Step-by-step explanation:
Given data
Cost of item= $420
Tax= $25.2
Required
The tax rate
=25.2/420*100
=0.06*100
=6%
Hence the tax rate is 6%
solve vw^2+y=x for w
Answer: The given equation is
And we have to solve for w .
For that we first get rid of y. And for that, we subtract y from both sides,
Now we need to separate v from w square, and for that, we divide both sides by v, that is
Now to get rid of square, we take square root to both sides. That is
And that's the required answer.
Step-by-step explanation:
Answer:
vw^2+y=x
vw²=x-y
w²=(x-y)/v
w=√{(x-y)/v}
A florist sold 14 flower bouquets yesterday, including 7 lily bouquets. Based on past data, how many of the next 20 bouquets sold should you expect to be lily bouquets?
Answer:
10
Step-by-step explanation:
From past data:
Fraction of lily sold :
Total flowers / number of lily
Total flowers = 14
Number of lily = 7
Fraction of lily = 14 /7 = 1/2
Going by these ;
Expected number of lilies in the next 20 bouquets sold :
Fraction of lily * number of flower in bouquet
1/2 * 20
= 10 lilies
is RATIONAL , IRRATIONAL,NON REAL NUMBERS
[tex] \sqrt{27[/tex]
Answer:
It's irrational
Step-by-step explanation:
the square root of 27 is equal to:
[tex]\sqrt{27} = \sqrt{3\cdot3\cdot3} = 3\sqrt{3}[/tex]
We know that [tex]\sqrt{3}[/tex] is an irrational number (but a real number), so [tex]3\sqrt{3}[/tex] is the same.
In case we need to prove that [tex]\sqrt{3}[/tex] is irrational, please leave a comment.
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.
