Step-by-step explanation:
Solution,
In the given cuboid, area of total surface (A)=280 cm²
Breadth ( b ) = 5 cm
Height ( h ) = 6 cm
Total surface area of cuboid = 2 ( lb + bh + lh )
or , Area = 2 ( lb + bh + lh )
or , 280 = 2 ( l × 5 + 5 × 6 + l × 6 )
or , 280 = 2 ( 11 l + 30 )
or , 2 ( 11 l + 30 ) = 280
or , 11 l + 30 = 280 ÷ 2
or , 11 l + 30 = 140
or , 11 l = 140 - 30
or , 11 l = 110
or , l = 110 ÷ 11
l = 10
Thus, the length is 10 cm...

What is the equation of this line?
y= 2x - 3
y= -1/2x- 3
y= -2x - 3
y= 1/2x - 3
Answer:
First option) y= 2x - 3
Step-by-step explanation:
[] The y-intercept, our b, is -3. This does not rule out any of the options as they all have -3.
[] The slope, when we have a graph with clear points, can be found with rise-over-run. We will pick a point and then count up and over to the next point.
-> Starting at the y-intercept, (0, 3), we count up 2 and to the right 1 for a slope of 2/1. This simplifies to 2.
[] Our equation is y = 2x - 3

For which value or values are the expressions 15 k+9 and 3(2k+3)+9k
Answer:
3(5k+3), 6k+9+27k
Step-by-step explanation:
which expression is equivalent to 12^-5 times 12^9?
a. 1/12^-45
b. 12^-45
c. 1/12^4
d. 1/12^-4
Answer:
D. 1/12^-4
Step-by-step explanation:
[tex]12^{-5}*12^{9}[/tex]
Since both exponents have the same base, we can add the exponents to get:
[tex]12^{-5+9}=12^{4}[/tex]
We can cross out A and B since they multiplied the two exponents, therefore both answers are wrong.
Now, let's try C and D.
C is wrong because it has a different base being raised to the same power.
D is correct. When you have a negative exponent, it is equivalent to the reciprocal of the base to the positive exponent.
The reciprocal of 1/12 is 12, and the positive of -4 is 4, therefore the answer is D.
Answer:
12^14

It's the correct answer
A bag contains 4 red marbles, 3 blue marbles and 6 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 1000th, that both
marbles drawn will be red?
Answer:
~0.143
Step-by-step explanation:
So, in total there are 15 marbles, and only 6 of them are red. So the first draw will have a chance of being red. Since you didn't mention placing it back, the next draw will have a chance of being red. It's , because you just took a red one out of the bag (leaving 5 left) and the total was lessened by one. To get the answer, you'd multiply both numbers together.
6/15 x 5/14 = 1/7 or (roughly) 0.143
Add or subtract each fraction
2 + 15/8
Answer:
3 7/8
Step-by-step explanation:
2 + 15/8 = 2/1 + 15/8
Let's add 2/1 + 15/8 like this:
2/1 × 8/8 = 16/8
16/8 + 15/8 = 31/8
Since that is an improper fraction, we will simplify it.
31/8 = 3 7/8

Answer:
40 in
Step-by-step explanation:
The Pythagorean theorem tells you the relationship between the sides of a right triangle.
b^2 +75^2 = 85^2
b^2 = 85^2 -75^2 = 1600
b = √1600 = 40
The length of the missing side is 40 inches.

Answer:
1) X + 234 = 633
2) t = 63
3) x = 12
Step-by-step explanation:
1 is simple subtraction, just subtract the whole by the number that is given. Then that will fill X.
2 is multiplication. If a variable is (for example, x) next to a number that means it is multiplying it by a hidden number. To find that, you multiply the number next to the variable. If the sum matches the solution, there you go.

-6= -15r+9s. Solve for s
Answer:
(5r-2)/3 = s
Step-by-step explanation:
-6= -15r+9s
Add 15r to each side
-6+15r= -15r+15r+9s
15r-6 = 9s
Divide each side by 9
(15r-6)/9 = 9s/9
(5r-2)/3 = s

What is the quadratic equation whose roots are 2 and 6, and whose leading coefficient is 5
Answer:
5x^2-8x + 12
Step-by-step explanation:
the formula for finding roots of equation is
x^2- (sum of roots)x + products of roots =0
and we already have the roots of the equation
so we add them to give 8
and multiply to give 12
hence the quadratic equation that has those roots with leading coefficient is 5x^2-8x + 12=0

Answer:
im guessing it is 78/100 because u circled 78
Step-by-step explanation:
because 21 + 1 + 78 = 100
so 78/100 is the fraction
Answer:
78/100 or 39/50 (simplified)
Step-by-step explanation:
First, let's convert 78% into a decimal.
78% = 0.78Now, we know that 0.78 is the same thing as 78/100. We can simplify 78/100 into 39/50, where 2 is the GCF
Thus, the answer is 78/100 or 39/50.
I need help trying to figure out what is the area in my given shape
The area of a triangle is base times height divided by two
In this figure, its
3*6/2=
9
help find area pls :(
Answer:
Total area = 26.13 ft²
Step-by-step explanation:
area of a triangle = 1/2 x base x height
From inspection, the base of the triangle = 3 x 2 = 6
and the height of the triangle = 4
⇒ area = 1/2 x 6 x 4 = 12 ft²
area of a semicircle = [tex]\frac{1}{2}\pi r^2[/tex]
⇒ area = [tex]\frac{1}{2} \times 3.14 \times 3^2[/tex]
⇒ area = 14.13 ft²
Total area = 12 + 14.13 = 26.13 ft²

One number is 3 less than 4 times a second number. The difference of the
first number and twice the second number is 7. What are the two numbers?
Show your work.
Answer:
the two numbers are 5 and 17
Step-by-step explanation:
4y - 3 = x
x - 2y = 7
to find y:
x - 2y = 7
(4y - 3) - 2y = 7
2y - 3 = 7
2y = 7 + 3
2y = 10
y = 10/2
y = 5
to find x :
4y - 3 = x
4 ( 5 ) - 3 = x
20 - 3 = x
17 = x
Dave wants to buy 5 games, 10 Funko Pops, and 6 toys. He was $2,614 .If each game is $50, each Funko Pop is $30, and each toy is $40. How much money does Dave have left?
Answer:
$1,824
Step-by-step explanation:
Games Dave wants to buy: 5
Cost of each game: $50
Cost of 5 games = $50 x 5
= $250
Funko pops Dave wants to buy: 10
Cost of each funko pop: $30
Cost of 10 funko pops = $30 x 10
= $300
Toys Dave wants to buy: 6
Cost of each toy: $40
Cost of 6 toys = $40 x 6
= $240
Sum of all Dave's things = ($250 + $300 + $240)
= $790
Money Dave has = $2,614
Money left with him = ($2,614 - $790)
= $1,824
Hence, $1,824 are left with Dave after buying 5 games, 10 Funko pops and 6 toys.
Pls correct me, if I am wrong :)

2) (Four students in a class do not have any siblings. This is 20% of the entire class.
How many students are in the class? HELPPP I HAVE A TEST TOMORROW THIS IS a test ) “solving percent with double number lines and mental math”
Answer:
16 students
Step-by-step explanation:
Knowing that 4 is 20% of a certain number is a great start. Think, how many times does 20 go into 100, 4. So then you multiply 4 with 4.
4 · 4 = 16
I’m confused, mostly on 4. How can you prove it, and are they parallel?
Answer:
It is parallel and yes you can prove it.
Step-by-step explanation:
I would use a tool that you can use to figure out the angle, check all the corners and if the smaller one are the same and the wider corners are the same then then would be parallel. That only works though if there was a line going through like your problems. If you had a graph it would be easier.
Radhika buys papaya at the rate of p(x) = x² – 12x – 220 per kg
(i) the factors of the given polynomial
(ii) if she purchase 5kg papaya, what money she have to pay?
Answer:
(i) The factors of the given polynomial is (x – 22) and (x + 10)
(ii) If she purchase 5kg papaya then she pays 110
Step-by-step explanation:
Given;p(x) = x² – 12x – 220 per kgTo Find;The factors of the given polynomialif she purchase 5kg papaya, what money she have to pay?(i)Now,
x² – 12x – 220 = 0
Splitting the middle term
x² – 22x + 10x – 220 = 0
x(x – 22) + 10(x – 22) = 0
(x – 22) + (x + 10) = 0
x – 22 = 0 or x + 10= 0
x = 22 or x = -10
Here, (-10) is the negative value hence it is not possible
So, The value of x is 22
The factors of the given polynomial is (x – 22) and (x + 10)
(ii)if she purchase 5kg papaya then,
we know the price of 1 kg papaya i.e., 22 per kg
So,
5 × 22 = 110
Thus, if she purchase 5kg papaya then she pays 110
