Margaret and Donovan are twins. They have each kept track of their heights every year since they were 5.
Donovan wrote an equation to track his height: h = 105 + 4.25(a - 5)
Based on the evidence shown, which statement correctly compares the twins' rates of growth?
Answer: B
Explanation:What we know:
Donovan's height can be expressed through the equation H = 105 + 4.25(a - 5) where H is height and a is ageMargaret's height is expressed through a given tableHow to solve:
We need to create a table for Donovan's height, compare it to Margaret's table, and then choose the appropriate statement. H will represent height, and a will represent age. B and c are constant values, and x is a coefficient to a-c
Process:Part 1 - DataSimplifying equation
Set up equation H = 105 + 4.25(a - 5)
Distribute H = 105 + (4.25a - 21.25)
Age 5
Set up equation H = 105 + (4.25a - 21.25)
Substitute H = 105 + [(4.25*5) - 21.25]
Simplify H = 105 + (21.25 - 21.25)
Simplify H = 105
Age 6
Set up equation H = 105 + (4.25a - 21.25)
Substitute H = 105 + [(4.25*6) - 21.25]
Simplify H = 105 + (25.5 - 21.25 )
Subtract H = 105 + 4.25
Solve H = 109.25
Age 7
Set up equation H = 105 + (4.25a - 21.25)
Substitute H = 105 + [(4.25*7) - 21.25]
Simplify H = 105 + (29.75 - 21.25)
Subtract H = 105 + 8.5
Solve H = 113.5
Continue for the following ages (8-10)
Part 2 - Table Comparison1. Create a table for both sets of data. Example:
______________________________________________
Age | 5 | 6 | 7 | 8 | 9 | 10 |
Mar. height (cm) | 101 | 105 | 109 | 113 | 117 | 121 |
Don. height (cm) | 105 | 109.25 | 113.5 | 117.75 | 122 | 126. 25 |
______________________________________________
2. Find which statement applies
2a. Margaret did not grow faster than Donovan
2b. Donovan did grow faster than Margaret
2c. Margaret and Donovan did not grow at the same rate
2d. There is enough data to draw a conclusion
Solution: BCheck:
We came to this conclusion by putting Donovan's data into a chart. We can check by writing an equation for Margaret's height. Then, use that equation with Donovan's to see the difference
Margaret's equation:
H = 4a + 81
Comparison (using ages 8 & 9):
8:
H= 4a + 81 | H = 105 + (4.25a - 21.25)
H = (4*8) + 81 | H = 105 + [(4.25*8) - 21.25)
H = 32 + 81 | H = 105 + 12.75
H = 113 | H = 117.75
9:
H = 117 | H = 122
________________________
113 < 117.75
117 < 122
Because the statement still holds true, answer B is correct.

Carrie buys 7/8 pound of red apples and 15/16 pound of green apples.
Which answer is the most accurate estimate for how many more pounds of green apples she buys than pounds of red apples?
0 pounds
12 pound
1 pound
Answer:
0 pounds
Step-by-step explanation:
Carrie buys 7/8 pound of red apples and 15/16 pound of green apples.
Which answer is the most accurate estimate for how many more pounds of green apples she buys than pounds of red apples?
Total number of green apples - Total number of red apples
Our expression: [tex]\frac{15}{16}-\frac{7}{8}[/tex]
[tex]\frac{15}{16}-\frac{7}{8} \\\\\frac{15}{16}-\frac{14}{16} \\\\\frac{1}{16}[/tex]
Since [tex]\frac{1}{16}[/tex] is not a full pound (1 pound), our answer will be 0 pounds.
Hope this helps!

Could anyone help me with these questions? I will mark brainliest and PLEASE show all the work.
Answer:
4: 321.5cm²
5: Length of fencing = 62.46cm, Area of Yard: 232cm²
6: Area of 1 sign: 3950cm². Paint cans needed: 237
Step-by-step explanation:
4:
Area of Machine = Area of Square - 1/4 Area of Circle taken away
Area of Machine = (20x20) - 1/4(π10²)
Area of Machine = 400 - 1/4(3.14 x 100)
Area of Machine = 400 - 1/4(314)
Area of Machine = 400 - 78.5 = 321.5cm²
5: The perimeter of this figure is the length of fencing needed. The area of the yard can be figured out:
Perimeter: We're missing one side. So what we need to see here, is that the figure has a hidden triangle. Do you see it? its a missing right angle triangle, and we can use the Pythagorean theorem to find the hypotenuse, which is the missing side:
a² + b² = c²
16² + 7² = c²
256 + 49 = c²
305 = c²
c ≅ 17.46cm
now that we know the last dimension of the trapezoid, the Perimeter is known to be 11 + 16 + 18 + 17.46 = 62.46cm
Area = 1/2(b1+b2) x h
Area = 1/2(11 + 18) x 16
Area = 14.5 x 16 = 232cm²
6:
Area of 1 Sign = Area of rectangle + Area of Triangle
Area of 1 Sign = (90x30) + 1/2(50 x 50)
Area of 1 Sign = 2700 + 25x50
Area of 1 Sign = 2700 + 1250 = 3950cm²
.: area of 6 signs will be 6 x 3950 = 23,700cm²
If one can of paint covers 1 squared meter, then it covers 100 squares cm. So it will take 23700/100 = 237 paint cans to cover all 6 signs :)

Hailey bought 3 pounds of apples for $7.70. How much did she pay per pound?
Answer:
About $2.57
Step-by-step explanation:
$7.70 / 3
2.566666667...
Rounds 2.566666667... to the nearest hundreth:
2.57
Double check:
$2.57 (a pound) × 3 (pounds) = $7.71
Since we rounded 2.566666667... to the nearest hundredth, the answer may be slightly off by a few decimals, and that's okay.
Therefore, this answer is correct.
Hailey pays about $2.57 per pound of apples.

Low-pressure systems
Get the Gizmo ready:
Click New until you see a low-pressure system, represented by the symbol L.
Check that Show Mobile Station B data and Show land are on.
Question: What weather patterns are associated with low-pressure systems?
Observe: Note how the air pressure changes as you move Station B towards the center of the low-pressure system.
What do you notice?
Why do you think this is called a low-pressure system?
Answer:
clouds
Step-by-step explanation:
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day.
I observe that when moving closer to station B the elevation as well as how close it is to the clouds is making the pressure more/less. also there could be more clouds there making the pressure more high or low.
Areas where the air is warmed often have lower pressure because the warm air rises. These areas are called low pressure systems. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.

Map of the City Zoo A triangle with points zebras, monkeys, and lions. The distance from zebras to monkeys is 52 feet and from monkeys to lions is x feet. A triangle with points lions, tigers, elephants. The distance from lions to tigers is 96 feet and from tigers to elephants is 78 feet. The path from the zebras to the monkeys is parallel to the path from the tigers to the elephants. What is the distance between the lions and monkeys? 1. Proportion: 52 78 = x 96 2. Cross-multiply: 4992 = 78x 3. Solve: The distance between the lions and the monkeys is feet.
Answer:
64 units
Step-by-step explanation:
Hello! This is a proportion problem
52 is a smaller proportion to 78.
X is a smaller proportion to 96.
Since this both have the same ratio scale, we can set them equal to each other, remembering to put the smaller number from each one on the top.
(52/78)=(x/96)
Now we can just solve for X:
(96*52)/(78) = 64 = X
Our answer is in feet so 64 feet is the distance between the lions and the monkeys.

(05.02)How many triangles can be made if one angle is 95° and another angle is obtuse? 1 2 More than 2 None
Answer:
D. None.
Step-by-step explanation:
Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.

Answer:
22ft^3
Step-by-step explanation:
Find the volume of one wooden cube block. Each of the edge length is 1/2
Volume of cube = l x w x h
l = 1/2 w = 1/2 h = 1/2
1/2 x 1/2 x 1/2 = 1/8
Then find the volume of the total box with how much total wooden blocks there are.
They are 176 wooden blocks.
Volume of one wooden cube block x the total number of wooden cube blocks = total volume of box.
So you do 1/8 x 176 and with that, the volume is 22ft^3.
