Answer:
1. D (5 fruit baskets)
2. C (4)
3. B (-10)
Step-by-step explanation:
1. Subtract 30 from 105 to get 75, as this is how much she paid for the annual membership fee. Then divide 75 by 15, this being the cost of the fruit baskets. Your answer would be 5, because 75/5=15.
2. Subtract 5 from 21. This would give you 16. Now you need to find out which number you would need to equal that 16. So 4x?=16. The answer would be 4.
3. Figure out what 5x? would need to be to get to -50. This would be -10, as -10x5=-50. Then just add in the 2, and since you're adding the positive 2 to a negative number, the negative number would be closer to 0, so -48.

A rectangular is completety filled with dice.Each dice has volume of 2cm³.The length of the box is 5cm grater than its width and its height is 5cm.Suppose the box holds at most 150dice.What are the posibble dimensions of the box
Answers
Answer:
length = 10.64 cm, width = 5.64 cm, and height = 5 cm.
Step-by-step explanation:
Total volume of dice that filled the box = (150 x 2) cm³
= 300 cm³
Let the length, width and height of the box be represented by l, w and h respectively.
So that;
l = (w + 5) cm
w = w
h = 5 cm
volume of the box = length x width x height
= (w + 5) x w x 5
= (w + 5) x 5w
= 5[tex]w^{2}[/tex] + 25w
volume of the box = 5[tex]w^{2}[/tex] + 25w
Since the box was completely filled by 150 dice, then;
total volume of dice = volume of the box
300 = 5[tex]w^{2}[/tex] + 25w
5[tex]w^{2}[/tex] + 25w - 300 = 0
Divide through by 5 to have;
[tex]w^{2}[/tex] + 5w - 60 = 0
Applying the quadratic expression,
w = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex]) ÷ 2a
where: a = 1, b = 5 and c = -60
(-5 ± [tex]\sqrt{5^{2} - 4(1*-60)}[/tex] ) ÷ 2
(-5 ± [tex]\sqrt{265}[/tex]) ÷ 2
(-5 ± 16.28) ÷ 2
(-5 + 16.28) ÷ 2 OR (-5 - 16.28) ÷ 2
5.64 OR -10.64
Thus, w = 5.64 cm
So that, l = (w + 5) = 10.64 cm
The possible dimensions of the box are: length = 10.64 cm, width = 5.64 cm and height = 5 cm.

Which correctly explains how to estimate 55 percent of 64? A. Round 55 percent to 40 percent and 64 to 60. Think of 40 percent as 1/4 so 1/4 of 60 is 15 B. Round 55 percent to 60 percent and 64 to 70. Think of 60 percent as 1/3 so 1/3 of 70 is 23.3 C. Round 55 percent to 50 percent and 64 and 70. Think of 50 percent as 1/5 so 1/5 of 60 is 12 or D. Round 55 percent to 50 percent and 64 to 60. Think of 50 percent as 1/2 so 1/2 of 60 is 30
Answers
Answer: Choice D
Round 55 percent to 50 percent and 64 to 60. Think of 50 percent as 1/2 so 1/2 of 60 is 30.
===================================================
Explanation:
There are many ways to estimate, but this is probably the easiest since 1/2 = 0.50 = 50%, and taking half of something is fairly straightforward and quick.
Taking half of 60 is like taking half of 6, except we stick at 0 at the end.
Half of 6 is 3
Half of 60 is 30
The estimate of 55% of 64 is 30
The actual value is
55% of 64 = 0.55*64 = 35.2
which isn't too far off.
-------------------------
Extra info:
Choice A is false because 40% is not equal to 1/4. Instead 1/4 = 0.25 = 25%Choice B is false because 1/3 = 0.333 = 33.3% approximately, so 1/3 is not equal to 60%Choice C is false because 1/5 = 0.20 = 20% and not 50%16 17 18

Dr. Cohn is testing how long it takes for a person's body to process a new medicine. She observes that the medicine is used by the body at a constant rate. For her latest test, Dr. Cohn starts with 15 milligrams of the medicine and notes that 12.6 milligrams remain unused after 1 hour. Which equation could Dr. Cohn use to solve for p, the percentage of the medicine that is used in 1 hour? A. p100=12.615 B. p100=2.415 C. p15=1002.4 D. p15=10012.6
Answers
Answer:
the options were not copied correctly, option B could be correct but it is missing the division signs:
B. p / 100 = 2.4 / 15
the percentage of medicine used in 1 hour:
p / 100 = (15 - 12.6) / 15 = 2.4 / 15
p / 100 = 0.16
p = 0.16 x 100 = 16%
another option could be C but it would be missing the multiplication signs:
C. p x 15 = 100 x 2.4
p x 15 = 240
p = 240 / 15 = 16%

If we could call on discord, zoom or anything like that i could easily explain. To type out the whole process would take all night
Step-by-step explanation:
Answer:
7. 42 degrees
8. 58 degrees
Step-by-step explanation:
Question 7
The three angles on the bottom line add up to 180.
65 + 31 + 2y = 180
2y = 84
So y = 42
Question 8
Let's start with the triangle with the 27 degree angle.
We have 27 + 90 + z = 180 (z is the top right angle)
z = 63 (which is also the bottom left angle of the triangle with the 32 degree angle).
63 + 32 + x = 180
x = 85 degrees
Now we look at the bottom polygon with the y degree angle we're trying to find.
We have one angle opposite x and another opposite z.
The angle opposite x + x = 180
The angle opposite x + 85 = 180
The angle opposite x = 95
The angle opposite z + z = 180
The angle opposite z + 63 = 180
The angle opposite z = 117
The sum of the interior angles of a polygon equals the number of sides less 2 * 180. We have four sides, so the interior angles add up to 360.
90 + 95 + 117 + y = 360
Therefore y = 58 degrees

An architect designs two similar triangular patios. The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°. The second patio has angle measures of (x + 20)°, 50°, and 60°. Find the values of x and y.
Answers
Given:
An architect designs two similar triangular patios.
The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°.
The second patio has angle measures of (x + 20)°, 50°, and 60°.
To find:
The values of x and y.
Solution:
We know that, corresponding angles of similar triangles are equal. So, the value of (x + 20)° must be 70°.
[tex]x+20=70[/tex]
[tex]x=70-20[/tex]
[tex]x=50[/tex]
The value of x is 50.
Now,
[tex](x+10)^\circ=(50+10)^\circ[/tex]
[tex](x+10)^\circ=(60)^\circ[/tex]
So, remaining angles must be equal, i.e., (y + 15)° and 50° are equal.
[tex]y+15=50[/tex]
[tex]y=50-15[/tex]
[tex]y=35[/tex]
Therefore, the values of x and y are 50 and 35 respectively.
The values of x and y are 50 and 35 respectively.
The corresponding angles of similar triangles are equal. Therefore,
The first patio angles are:
x + 10
y + 15
70°
The second patio angles are ;
x + 20
50°
60°
Therefore,
x + 20 = 70
x = 70 - 20
x = 50
y + 15 = 50
y = 50 - 15
y = 35
