Step-by-step explanation:
4 × 5 × 1 = 20 (cm³)
Hope it help, please give me Brainlest!
Answer:
20
Step-by-step explanation:
The formula for volume:
[tex]V=length*width*height\\\\V=lwh[/tex]
Multiply all given values together:
[tex]V=4*5*1\\\\V=20*1\\\\V=20[/tex]
The volume of the box is 20cm³.
:Done
Note:
"Cubic" centimeters means cm³. The exponent is used because you multiplied 3 dimensions.
Another example would be with area. To find this, you multiply length by width, resulting in area², because you mutliplied 2 dimensions.

Answer:
Four times a plus b equals nine times a
Suppose a box contains 10 coins, where three of them are type-A and seven of them are type-B. The probability of head is 0.4 if we toss a type-A coin and 0.6 for a type-B coin. One person chooses one coin at random and tosses it three times. What is the probability that this coin is type-A if the outcome is two heads out of three tosses?
Answer:
0.222
Step-by-step explanation:
Given that:
For Type A coins = 3
The probability of head in a type A coin i.e. (p) = 0.4
Then, the probability of getting a tail (q) = 1 - p = 1 - 0.4 = 0.6
For Type B coins = 7
The probability of head in a type B coin i.e. (p) = 0.6
Then, the probability of getting a tail (q) = 1 - p = 1 - 0.6 = 0.4
One person who tosses a coin three times get a probability of obtaining a head twice.
Using, the formula:
=[tex]^nC_r \times p^r \times q^{n-r}[/tex]
For Type A coin;
The probability of getting two heads in three tosses is:
[tex]= ^3C_2 \times 0.4^2 \times 0.6^{1}[/tex]
[tex]=\dfrac{3!}{2!(3-2)!} \times 0.4^2 \times 0.6^1[/tex]
= 0.288
For Type B coin;
The probability of getting two heads in three tosses is:
[tex]= ^3C_2 \times 0.6^2 \times 0.4^{1}[/tex]
[tex]=\dfrac{3!}{2!(3-2)!} \times 0.6^2 \times 0.4^1[/tex]
= 0.432
Since we have two heads out of three tosses, the probability that the coin is type A is = (P) of choosing coin A × (P) of obtaining two heads from three tosses) / total probability of getting two heads from three tosses.
However;
(P) of choosing coin A = 3/10 = 0.3
(P) of choosing coin B = 7/10 = 0.7
∴
Given that, we obtain two head from three tosses, the (P) that the coin type is A is:
[tex]= \dfrac{(0.3 \times 0.288)}{ (0.3 \times 0.288 + 0.7 \times 0.432)}[/tex]
[tex]= \dfrac{(0.0864)}{ (0.0864 + 0.3024)}[/tex]
= 0.222

Answer:
A
Step-by-step explanation:
Gabriella invested $73,000 in an account paying an interest rate of 3%
compounded continuously. Mila invested $73,000 in an account paying an interest
rate of 3% compounded quarterly. After 5 years, how much more money would
Gabriella have in her account than Mila, to the nearest dollar?
Answer:
Gabriella will make $61 more than Mila after 5 years
Step-by-step explanation:
Gabriella Data
Principal Amount P= $73,000
Rate r = 3% or 0.03
Compounded continuously
Time t = 5 years
The formula used is: [tex]A=Pe^{rt}[/tex]
Putting values and finding A
[tex]A=Pe^{rt}\\A=73000e^{0.03*5}\\A=73000e^{015}\\A=84813.899\\A\approx84814[/tex]
So, After 5 years Gabriella will have $84814
Mila Data:
Principal Amount P= $73,000
Rate r = 3% or 0.03
Compounded quarterly n = 4
Time t = 5 years
The formula used is:[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
Putting values and finding A
[tex]A=P(1+\frac{r}{n})^{nt}\\A=73000(1+\frac{0.03}{4})^{4*5}\\A= 73000(1+0.0075)^{20}\\A= 73000(1.0075)^{20}\\A=73000(1.161)\\A=84753[/tex]
So, After 5 years Mila will have $84753
Now subtracting to find the difference 84814-84753 = 61
So, Gabriella will make $61 more than Mila after 5 years

At a lightbulb manufacturing plant, 2% of the lightbulbs are found defective. If the plant had 56 defective lightbulbs on a certain day, how many did it manufacture that day?
Answer:
2800 lightbulbs
Step-by-step explanation:
Divide 56 by 2% to cancel out the multiplication used to find the amount of defective lightbulbs.
Which expression would be easier to simplify if you used the associative property to change the grouping?
A. 85 + (120 + 80)
B. [-40 + (60)] + 52
C. (2 + 3/7) + 4/7
D. 4 + (1.2 + (-0.2))
Answer:
C
Step-by-step explanation:
In A and B, the numbers involved in expressions are integers.
Hence, they can be easily added or subtracted.
In C, the numbers involved in expression are fractions which are not grouped together.
They can be added but by using associative property, it becomes much more easier.
That is, grouping fractions.

Answer:
3) Equation of line is: 5x-8y+34=0
4) Equation of line is: 5x+y+5=0
Step-by-step explanation:
3) Equation of line parallel to [tex]5x-8y+12=0[/tex] and through point (-2,3)
When two lines are parallel they have same slope.
Converting the given equation [tex]5x-8y+12=0[/tex] to Slope intercept form i.e [tex]y=mx+b[/tex]
[tex]5x-8y+12=0\\-8y=-5x-12\\y=-\frac{5x}{-8}-\frac{12}{-8}\\y= \frac{5x}{8}+\frac{3}{2}[/tex]
Now comparing with [tex]y=mx+b[/tex] we get value of m i.e 5/8 which is slope of line.
Now, finding y-intercept using point (-2,3) and slope 5/8
[tex]y=mx+b\\3=\frac{5}{8}(-2)+b\\3=-\frac{5}{4}+b\\b=3+\frac{5}{4}\\b=\frac{3*4+5}{4}\\b=\frac{12+5}{4}\\b=\frac{17}{4}[/tex]
So, y-intercept is b= 17/4
The required equation is:
[tex]y=mx+b\\y=\frac{5x}{8}+\frac{17}{4}[/tex]
Writing in Standard form
[tex]y=\frac{5x}{8}+\frac{17}{4}\\y=\frac{5x+17*2}{8} \\y=\frac{5x+34}{8} \\8y=5x+34\\5x-8y+34=0[/tex]
So, Equation of line is: 5x-8y+34=0
4) Equation of line perpendicular to [tex]x-5y+2=0[/tex] and through point (-2,5)
When two lines are perpendicular they have opposite slope i.e m=-1/m.
Converting the given equation [tex]x-5y+2=0[/tex] to Slope intercept form i.e [tex]y=mx+b[/tex]
[tex]x-5y+2=0\\-5y=-x-2\\y=-\frac{x}{-5}-\frac{2}{-5}\\y= \frac{x}{5}+\frac{2}{5}[/tex]
Now comparing with [tex]y=mx+b[/tex] we get value of m i.e 1/5 which is slope of given line.
Slope of required line will be: m=-1/m = -5
Now, finding y-intercept using point (-2,5) and slope -5
[tex]y=mx+b\\5=-5(-2)+b\\5=10+b\\b=5-10\\b=-5[/tex]
So, y-intercept is b= -5
The required equation is:
[tex]y=mx+b\\y=-5x-5[/tex]
Writing in Standard form
[tex]y=-5x-5\\5x+y+5=0[/tex]
So, Equation of line is: 5x+y+5=0

3) A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then
find AB
Answer:
AB = 8
Step-by-step explanation:
A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then find AB
Step 1
Find x
BC = AB + AC
8x + 5 = 2x + 4 + 3x + 7
Collect like terms
8x - 2x - 3x = +4 + 7 - 5
3x = 6
x = 2
Step 2
Find AB
= AB= 2x + 4
AB = 2(2) + 4
AB = 4 + 4
AB = 8

6x+7
To solve for the lengths of the right triangle sides, which equation is correct?
A. x² = (4x - 1)² + (6x + 7)?
B. x2 +(6x + 7)2 = (4x - 1)2
c. x² = (4x - 1)² – (6x + 772
D.x² + (4x - 1)2 = (6x + 7)?
4x-1
To solve for the lengths of the right triangle sides, equation is correct.
(Type A, B, C, or D.)
Answer:
A. [tex]x^2 = (4x - 1)^2 + (6x + 7)^2[/tex]
Step-by-step explanation:
The question seems to be incomplete. However, we'll make the following assumption.
[tex]Opposite = 6x + 7[/tex]
[tex]Adjacent = 4x - 1[/tex]
[tex]Hypothenuse = x[/tex]
Pythagoras theorem states that:
[tex]Hypothenuse^2 = Opposite^2 + Adjacent^2[/tex]
Substitute values for Hypothenuse, Opposite and Adjacent.
This gives
[tex]x^2 = (6x + 7)^2 + (4x - 1)^2[/tex]
or
[tex]x^2 = (4x - 1)^2 + (6x + 7)^2[/tex]
From the list of given options.
