Answer:
a.) likely
b.) unlikely
c.) equally
Step-by-step explanation:
A.) ~~~ there are more numbers less than 9 than numbers greater than or equal to 9, so rolling this is likely
B.) ~~~ There are only 4 multiples of 3, so rolling this is unlikely.
C.) ~~~ There are an equal amount of numbers greater than 6 and less than or equal to 6, so the chances of this are 50/50, or equal

[tex]\boxed{\pink{\sf \leadsto Yes \ there \ is \ a \ solution \ of \ the \ given \ inequality .}}[/tex]
Step-by-step explanation:A inequality is given to us and we need to convert it into standard form and see whether if it has a solution . So let's solve the inequality.
The inequality given to us is :-
[tex]\bf\implies |2y + 3 | - 1 \leq 0 \\\\\bf\implies |2y+3|\leq 1 \\\\\bf\implies (|2y+3|)^2 \leq 1^2 \\\\\bf\implies (2y+3)^2 \leq 1 \\\\\bf\implies (2y)^2+3^2+2(2y)(3) \leq 1 \\\\\bf\implies 4y^2+9+12y - 1 \leq 0 \\\\\bf\implies 4y^2+12y+8 \leq 0 \\\\\bf\implies 4( y^2 + 3y + 2 ) \leq 0 \\\\\bf\implies y^2+3y +2 \leq 0 \:\:\bigg\lgroup \purple{\bf Standard \ form \ of \ inequality }\bigg\rgroup \\\\\bf\implies y^2y+2y+y+2 \leq 0 \\\\\bf\implies y(y+2)+1(y+2)\leq 0 \\\\\bf\implies ( y+2)(y+1)\leq 0 \\\\\bf\implies \boxed{\red{\bf y \leq (-2) , (-1) }}[/tex]
Let's plot a graph to see its interval . Graph attached in attachment .
Now we can see that the Interval notation of would be ,
[tex]\boxed{\boxed{\orange \tt \purple{\leadsto}y \in [-2,-1] }}[/tex]
Hence the standard form of inequality is y²+3y +2 ≤ 0 and the Solution set of the inequality is [ -2 , -1 ] .Two boats leave the same place at the same time. The first boat heads due north at 10 kilometers per hour. The second boat heads due west at 16 kilometers per hour. After 2.5 hours, how fast is the distance between the boats increasing
Answer:
18.87 km/hr
Step-by-step explanation:
First boat is heading North with a speed of 10 km/hr.
Second boat is heading West with a speed of 16 km/hr.
Time for which they move = 2.5 hours
To find:
The speed at which the distance is increasing between the two boats.
Solution:
Let the situation be represented by the attached diagram.
Their initial position is represented by point O from where they move towards point A and point B respectively.
[tex]Distance = Speed \times Time[/tex]
[tex]Distance\ OA = 10 \times 2.5 = 25\ km[/tex]
[tex]Distance\ OB = 16 \times 2.5 = 40\ km[/tex]
We can use Pythagorean Theorem to find the distance AB.
AB is the hypotenuse of the right angled [tex]\triangle AOB[/tex].
According to Pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow AB^{2} = OA^{2} + OB^{2}\\\Rightarrow AB^2 = 25^2 + 40^2\\\Rightarrow AB^2 = 2225^2\\\Rightarrow AB^2 \approx 47.17\ km[/tex]
The speed at which distance is increasing between the two boats is given as:
[tex]\dfrac{47.17}{2.5} \approx 18.87\ km/hr[/tex]

write (4x^4)^2 without exponents
Answer:
256x * 16
Step-by-step explanation:
[tex](4x^{2} * 4)^{2}[/tex]
(4x * 4x * 4) * (4x * 4x * 4 )
(16x * 4 ) * ( 16x *4)
16x * 16x = 256x
4 * 4 = 16
256x * 16
hope this helped a little
* = multiply
The given expression without exponent is
[tex]4 \cdot 4 \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x[/tex]
Given :
[tex](4x^4)^2[/tex]
Explanation
We need to write the given without exponents
outside exponent is 2 . so we multiply the parenthesis twice
[tex](4x^4)^2\\4x^4 \cdot 4x^4\\16 \cdot x^4 \cdot x^4\\ 16 \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x\\4 \cdot 4 \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x[/tex]

find the difference.
(4−5y)−2(3.5y−8)
Answer:
-12y + 20
Step-by-step explanation:
First, you simplify each term:
apply the distributive property:
4 - 5y - 2 (3.5y) - 2 x -8
Multiply 3.5 by -2:
4 - 5y - 2 (3.5y) - 2 x -8
Multiply -2 by -8:
4 - 5y - 7y +16
Next, we simplify by adding terms:
Add 4 + 16:
-5y - 7y + 20
Subtract 7y from 5y:
-12y + 20
Hence the simplified form is -12y + 20

A new health drink has 120% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 50 mg. How many milligrams of the vitamin is in the drink?
Answer:
60 mg
Step-by-step explanation:
Given that:
Recommended daily allowance for the Vitamin = 50mg
Drink contains 120% of the recommended daily allowance ;
Number of milligram of the Vitamin contained in the drink is :
120% of recommended daily allowance
(120 /100) * 50
1.2 * 50
= 60 mg

Jacks father drives to work in 30 min when driving at his usual speed. When traffic is bad, he drives 30mph slower and the trip takes one hour longer. How far is Jacks Fathers work from home in miles
Answer:
The distance of Jack's Father's work from home in miles is 45 miles.
Step-by-step explanation:
a) Data and Calculations:
Normal time taken by Jack's father to drive to work = 30 minutes
Time taken when traffic is bad = 1 hour longer
Speed when traffic is bad = 30 mph slower
Distance covered when traffic is bad, with time taken as 1 hour 30 minutes = time * speed = 1.5 * 30 = 45 miles
b) Jack's father normally drives at 90 mph (45 *2), this is why it normally takes him 30 minutes between his home and workplace when the traffic is not bad. However, when traffic is bad, it takes him one hour longer and he drives at 30 mph slower.

rob has 7.8 ounces of tuna salad. If she makes three sandwiches with an equal amount of tuna on each, how much tuna does she put on each one?
Answer:
2.6 tuna
Step-by-step explanation:
Amount of tuna salad rob has = 7.8ounces
Amount of sanndwiches made = 3sandwiches
If she had equal amount of tuna on each sandwiches
Amount of tuna in each = Total amount of tuna/Amount of sandwiches
Amount of tuna in each = 7.8/3
Amount of tuna in each = 2.6 tuna
Hence she put 2.6 tuna in each sandwiches
