The temperature at 10:00 a.m was -3 and increased 2.25 each hour for the next 5 hours.What was the temperature at 3:00pm?
Answers
9514 1404 393
Answer:
8.25°
Step-by-step explanation:
The increase over 5 hours was ...
(5 h) × (2.25 °/h) = 11.25°
When that is added to the starting value, the ending value is ...
-3° +11.25° = 8.25°
The temperature at 3:00 pm was 8.25°.

chloe has three dogs. Corky weighs twice as much as muffin.Rufus weighs twice as much as corky. the total weight of the dog is 77 pounds. how much does each dog weigh?
Answers
Answer:
Corky = c = 22 pounds
Muffin = m = 11 pounds
Rufus = r = 44 pounds
Step-by-step explanation:
Let the weight of each dog be represented as
Corky = c
Muffin = m
Rufus = r
The total weight of the dog is 77 pounds.
c + m + r = 77
Corky weighs twice as much as muffin.
c = 2m
m = c/2
Rufus weighs twice as much as corky.
r = 2c
Hence
c + c/2 + 2c = 77
3.5c = 77
c = 77/3.5
c = 22 pounds
m = c/2
m = 22/2
m = 11 pounds
r = 2c
r = 2 × 22
r = 44 pounds
Each dog weighs:
Corky = c = 22 pounds
Muffin = m = 11 pounds
Rufus = r = 44 pounds

Recall that with base-ten blocks: 1 long 10 units, 1 flat 10 longs, and 1 block 10 flats. What is the fewest number of multibase blocks that can be used to represent the corresponding numeral in the given base?
a. 20 longs in base seven
b. 10 longs in base three
Answers
a. The answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.
b. The answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.
a. To represent 20 longs in base seven, we need to find the fewest number of multibase blocks required.
In base seven, we have the following conversions:
1 long = 1 unit
1 flat = 10 units
1 block = 10 flats
To represent 20 longs, we can use 2 flats (each flat representing 10 units) and 0 units since there are no remaining units.
So, the fewest number of multibase blocks required would be 2 flats.
Therefore, the answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.
b. To represent 10 longs in base three, we need to find the fewest number of multibase blocks required.
In base three, we have the following conversions:
1 long = 1 unit
1 flat = 3 units
1 block = 3 flats
To represent 10 longs, we can use 3 flats (each flat representing 3 units) and 1 unit since there is one remaining unit.
So, the fewest number of multibase blocks required would be 3 flats and 1 unit.
Therefore, the answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

{Note: If one is interested, the following information provides a "step-by-step" explanation.}:
____
Method 1)
Make a ratio:
"(2x + 10) : 40 :: 3:5 " ;
Write this ratio in the form of a fraction:
→ " \(\frac{(2x+10)}{40}=\frac{3}{5}\) ";
Cross-factor multiply :
Note: Given: " \(\frac{a}{b} = \frac{c}{d}\) " ; "\(ad = bc\)" ; ["\(b\neq 0 ; d\neq 0\)"] ;
→As such: " \(5(2x+10) = 3 * 40\) " ; Solve for "x";
⇒ { 5(2x + 10} / 5 = (3 * 40)/5 ; ⇒ 2x + 10 = 120/5 ;
to get: 2x + 10 = 24 ;
→ or: "{5(2x + 10}/5 = \(\frac{4*30}{5}\) ";
⇒ On the "right-hand side" of the equation:
The "30" in the numerator cancels to "6" ; and the "5" in the denominator cancels to "1" ; {since: "30÷5 = 6" ; & since: "6÷6 = 1"} ;
and we can rewrite the equation:
⇒ 2x + 10 = 24 ; → Subtract "10" from each side of the equation:
→ 2x + 10 - 10 = 24 - 10 ; to get: " 2x = 14 " ;
⇒Now, divide each side of the equation by "2" ;
to isolate "x" on one side of the equation; & to solve for "x" :
→ 2x/2 = 14/2 ; to get: " x = 7 " .
________
Alternately, when we have: " 2x + 10 = 24 " ; we can simplify this equation by dividing each side of the equation by "2" ;
________
⇒ {2x+10}/2 = {24/2} ;
to get: → (2x/2) + (10/2) = (24/2); → to get: "x + 5 = 7" ;
⇒ Then: Subtract "5" from each side of the equation; to isolate "x" on one side of the equation; & to solve for "x" ;
⇒ x + 5 - 5 = 12 - 5 ; to get: " x = 7 " ;
________
Method 2)
Write this ratio in the form of a fraction:

⇒ Now; to solve for "x" ; → " \(5(2x+10) = 3 * 40\) " ;
⇒ Note: Re: the "left-hand side" of the equation:
________
" 5(2x + 10) " ;
Note the "distributive property of multiplication" :

As such:
→ " \(5(2x+10)\) " ↔= " (5*2x) + (5*10) = (10x) + (50) = 10x + 50 ;
→ Then, take note of the "right-hand side" of the equation:
⇒ (40*3) = 120 ;
→ Now, we can rewrite the equation as: " 10x + 50 = 120 " ;
⇒To solve for "x": We can subtract "50" from each side of the equation:
⇒ 10x + 50 - 50 = 120 - 50 ; → to get: "10x = 70 " ;

________
10x/10 = 70/10 ; to get: "x = 7" .
________
Alternately: " 10x + 50 = 70 " ; Solve for "x" ;

________
Alternately: We have: "10x + 50 = 120"; Solve for "x";

Malcolm has $50 gift card to a local car wash and order is the ultimate car wash each visit is $8.95
Answers
The amount cheaper is the car washes Malcolm orders than the car washes Martha's order is $13.
The correct answer choice is option B.
How much cheaper is the car washes Malcolm orders than the car washes Martha's order?Malcolm's gift card = $50.
Cost Malcolm's car wash per visit = $7
Martha's gift card = $180
Cost Martha's car wash per visit = Difference between gift card balance of first and second visit
= $180 - $160
= $20
How cheap is the car washes Malcolm orders than the car washes Martha's order = $20 - $7
= $13
Therefore, Malcolm's car wash is cheaper than Martha's car wash by $13

On graph A, the group of mammals seems to have one-quarter as much as the group of fish.
Answers
On graph B, the group of birds seems to have twice as much as the group of mammals.
The change in scale on the y-axis from 50 to 85 in increments of 5 in Graph A to 0 to 80 in increments of 10 in Graph B makes the differences between the groups appear larger in Graph B.
As a result, the height of the bar for birds is approximately twice as much as the height of the bar for mammals in Graph B, which may not be apparent in Graph A.
Therefore, the correct option is (a) On graph B, the group of birds seems to have twice as much as the group of mammals.
