Why
is 30% of 40
and 40% of 30 the
same?
Answer:
no it's different 30% would be 12 and 40% would be 16 if it was going into 30 now mark as brainliest
Answer:
In both cases you are really multiplying the same numbers together.
Step-by-step explanation:
30% of 40 would be 30 x 40 x 0.01 = 12
or 0.30 x 40 = 12
40% of 30 would be 40 x 30 x 0.01 = 12
or 30 x 0.40 = 12
which functions have a range of
Answer:
Option (4) and (5)
Step-by-step explanation:
Option (1)
f(x) = -(x + 1)² - 4
Since, given function has the vertex = (-1, -4) and the parabola is the opening downwards,
Range of the function → (-∞, -4]
Option (2)
f(x) = [tex]2^{x+3}[/tex]
Horizontal asymptote of the function is,
y = 0
Therefore, range of the given function → (0, ∞)
Option (3)
f(x) = x² + 7x - 9
= x² + 2(3.5)x + (3.5)² - (3.5)² - 9
= (x + 3.5)²- 12.25 - 9
= (x + 3.5)²- 21.25
Vertex of the parabola is (-3.5, -21.25) and parabola is opening upwards.
Therefore, range of the function → [-21.25, ∞)
Option (4)
f(x) = -4x + 11
Range of this function is (-∞, ∞).
Option (5)
f(x) = [tex]\frac{2}{3}x-8[/tex]
Range of the function is (-∞, ∞).
Options (4) and (5) are the correct options.

Option 2
Step-by-step explanation:
it easy Add them all up and then you get 47/16 then divide them and convert it to mixed number and then you get 2 15/16
Answer:
2 15/16
Step-by-step explanation:
We need to make sure all fractions have the same denominator.
The LCM (least common denominator) is 16.
Now we have to multiply each nunber except 2 1/16 to get a numerator of 16.
1/2: 1x8= 8, 2x8= 16→ 8/16
3/8: 3x2= 6, 8x2= 16→ 6/16
Now every add everything all up.
8/16 + 6/16 + 2 1/16 = 2 15/16
2 15/16 is our answer.
Pls how can I round the following figures to the nearest ten, hundred, thousand (1)46,586 (2)213,340 (3)391,565
Answer:
Step-by-step explanation:
Sample Nearest 10 nearest hundred nearest thousand
1 46590 46500 47000
2 213340 213300 213000
3 391560 391600 392000
The table above is actually the answers. The rule is this:
If you want to round to the nearest 10, go to the tens place.Observe the units placeIf the units place is 5 or more, round the 10s place up one.Show the units place as a zeroIf the units place is 4 or less, leave the 10s place alone. Make the units place 0. Rounding to the tens place always gives a 0 at the units placeIf you want to round to the 100s place
Round the hundreds place using the five or more or 4 or less rule from the above rules.You should have 2 zeros at the end.If you want to round to the 1000s place
Round the thousands place using the five or more or 4 or less rule from the above rules.You should have 3 zeros at the end.The Glazed Donut Shop made 120 donuts, and 48 of them are filled with jelly. What percent of the donuts are filled with jelly?

What is the distance of AB
Answer:
It's around 9.22
Step-by-step explanation:
Answer:
[tex]\sqrt{85}[/tex]
Step-by-step explanation:
Distance formula.
(-7, -2) (2, -4)
-7 minus 2, you get -9. Squared is 81.
-2 minus -4 gets you 2. Squared is 4.
Add 81 & 4. You get 85.
Square root 85, there's your answer.

During two games, the number of points scored by a basketball team increased from 75 to 87. By what percentage did the number of points scored increase?
A - 12%
B - 14%
C - 86%
D - 16%
Answer:
D - 16%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
percent change = (87 - 75)/75 * 100%
percent change = 12/75 * 100%
percent change = 4/25 * 100%
percent change = 16%
Answer: D - 16%

The number of defective laptops = 6/145 * 100 as a percent.
The number of defective laptops = 4.13% in a sample of 145
A: False. The percentage should be the same for 290 laptops. The % does not change. The number of defective laptops will change (12)
B: True. It is a reason assertion that about 4% of all laptops will be defective.
C: True. It is not reasonable to assume that only 0.5 laptops will be defective. .5% is too small.
D: True. 10% is too high.

maggie is baking 8 dozen cookies. the recipe she is using makes 24 cookies. she needs 2/3 cup of flour for one recipe. how much flour will she need?
Answer: 2 2/3 cups of flour
Step-by-step explanation:
Maggie is baking 8 dozen cookies.
8 dozen is equal to 96 cookies as 8×12=96
One recipe is equal to 24 cookies and for each recipe she'll need 2/3 cup of flour.
So you divide 96 by 24 which is equal to 4.
Therefore, you will need 4 recipes worth of flour.
4×2/3=2 2/3
So Maggie would need 2 2/3 cups of flour
