Answer:
9t²+(t²+2)
Step-by-step explanation:
The product of 9 and t squared is expressed as 9×t² (product means multiplication)
9×t² = 9t²
Also, sum of the square of t and 2" is expressed as t² + 2 (sum means addition)
Finally, if the product of 9 and t squared, increased by the sum of the square of t and 2", the final expression will be the sum of the two expressions gotten. {Increment also means addition} i.e 9t²+(t²+2)
The algebraic expression is 9t²+(t²+2)
George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL. What is the volume of the object?
Answer: 20 mL
Step-by-step explanation:
According to Archimedes, the upward force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.
i.e. weight of the object = weight of the fluid displayed
Given: George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL.
So, the volume of the object = New volume - Original volume
= 45 mL - 25 mL
= 20 mL
Hence, the volume of the object =20 mL
Ari is jogging at an average rate of 2.25 meters per second. Find the time it will take him to jog 270 meters.
Answer:
120 seconds/2 minutes
Step-by-step explanation:
divide the distance (270 m) by the rate (2.25 m/s) and you have 270/2.25 = 120 seconds, or 2 minutes.
It will take Ari 120 seconds to jog 270 meters.
To find the time it will take Ari to jog 270 meters at an average rate of 2.25 meters per second, we can use the formula:
Time = Distance / Rate
where:
Distance = 270 meters
Rate = 2.25 meters per second
Time = 270 meters / 2.25 meters per second
Time = 120 seconds
Therefore, it will take Ari 120 seconds to jog 270 meters.

True or False: by using the additive inverse property -64 - (-17) can be rewritten as -64 + 17
Step-by-step explanation:
Additive inverse is when you have a positive number, for example, and it becomes a negative.
Example: 8
The additive inverse of 8 is -8.
So the answer is false.
-64+17 and -64-(-17) is an example of communative property.

To make lemonade , Kate uses 1 cup of lemon juice and 2 cups of sugar. If she makes a larger amount of lemonade with 10 cups of sugar, how many cups of lemon juice does she need?
Answer:
5 cups
Step-by-step explanation:
Answer:
1/2 : 1
2 : 4
3 : 6
Notice that every ratio consists of a number and double the number.
For 1/2 cup lemon juice, use 1 cup sugar.
The amount of sugar is twice the amount of lemon juice.
The ratio is 1:2
Since you are told the ratio is 1:r, that means r is 2.
The unit rate is 2 cups sugar per cup of lemon juice.

19. What is the coordinate of the midpoint of the segment formed by the two points you found in Exercises 17 and 18?
Please explain
Answer:
0
Step-by-step explanation:
To find the coordinate of the midpoint of segment QB, first, find the distance from Q to B.
QB = |4 - 8| = |-4| = 4
The coordinate of the midpoint of QB would be at ½ the distance of QB (½*4 = 2).
Therefore, coordinate of the midpoint of QB = the coordinate of Q + 2 = 4 + 2 = 6
OR
Coordinate of B - 2 = 8 - 2 = 6
Coordinate of the midpoint of QB = 6
Coordinate of W = -8
Coordinate of A = 0
distance from W to A (WA) = |-8 - 0| = |-8| = 8
The coordinate of the midpoint of WA would be at ½ the distance of WA = ½*8 = 4.
Therefore, coordinate of the midpoint of WA = the coordinate of W + 4 = -8 + 4 = -4
Or
Coordinate of A - 4 = 0 - 4 = -4
Coordinate of the midpoint of WA = -4
Now, let's find the midpoint between the two new coordinates we have found, which are -4 and 4
Distance of the segment formed by coordinate -4 and 4 = |-4 - 4| = |-8| = 8
Midpoint = ½*8 = 4
Coordinate of the midpoint = -4 + 4 = 0
Or
4 - 4 = 0

3 things to keep 1: It takes a garage owner 45 minutes to travel between his two garages 60 miles apart. Travelling at the same speed, how long would it take him to travel to his home 25 miles away? here it is 45/60 not 60/45 so minutes on top of miles 2: A jet travels 320 km in 20 minutes. How far will it fly in 30 minutes? here minutes is bottom, so 320/20 3: A boy cycles 20km in 140 minutes. How long would it take him to cycle 8km, at the same speed? km is bottom and minutes is on top, so 140/20 why is does it exactly does it keep changing what's on top? Is miles the only one allowed to have the smaller number on top, meanwhile km or under has to have the highest number first?

Step-by-step explanation:
By hit and trial method,
Given series of fractions will be,
[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex]
Since, [tex]\frac{3}{6}=\frac{3\times 1}{3\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]\frac{7}{14}=\frac{7\times 1}{7\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]\frac{29}{58}=\frac{29\times 1}{29\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
Therefore, [tex]\frac{1}{2}=\frac{1}{2}=\frac{1}{2}[/tex] is the reduced form of the fractions.
[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex] will be the answer.

Donis bought a t-shirt for $15 and jeans for $35.50. If the sales tax rate is 8.25%. What is the sales tax for the t-shirt and jeans in dollars and cents? *
====================================================
Explanation:
15+35.50 = 50.50 dollars is the total before tax is applied.
Take 8.25% of this to get
0.0825*50.50 = 4.16625
and this rounds to 4.17, which is the amount of sales tax charged.
$4.17 = 4 dollars + 17 cents
---------
Extra info:
The grand total will be 50.50+4.17 = 54.67
Another way to get the grand total is to multiply 1.0825 by the previous subtotal (50.50) getting 50.50*1.0825 = 54.66625 and that rounds to 54.67
The multiplier 1.0825 effectively means "increase by 8.25%"
