Answer:
x=41
Step-by-step explanation:
using pythagors theorem
a^2 + b^2 =c^2
here 9 and 40 are the legs of triangle so let them be a nd b respectively.And x is hypotenuse so let it be c
9^2 + 40^2 = x^2
81 + 1600 = x^2
1681 = x^2
[tex]\sqrt{1681} = x[/tex]
41 =x
The object below is made with six identical cubes. Each cube edge is 3 inches long.
As
3 in.
What is the surface area of the object in square inches?
Answer:
306 square inches.
Step-by-step explanation:
All surfaces of the cubes are exposed to the outside except 2 ( where 2 of the cubes join).
6 separate cubes have 6 * 6 faces exposed so this object has 36 - 2 = 34 surfaces exposed.
Each face of one cube = 3*3 = 9 in^2.
Therefore the surface area = 9 * 34 = 306 in^2.

Answer:
the first one
Step-by-step explanation:
all created functional values must always be negative, because "absolute value" Shays creates only positive numbers, and then the "-" in front makes then sure we have only negative numbers.
that rules out the third and fourth answer option.
to decide between first and second answer, I choose to see, when the function should deliver 0 as functional value.
f(x) is 0, when x+3 is 0. and that is only possible for x=-3.
so, at x=-3, y=0.
and that is only true for the first answer option.

How many pages would same have finished in 126 minutes
A.18
B.13
C.24
D.42
Answer:
Sam will finish 42 pages in 126 minutes.
Step-by-step explanation:
Number of pages read by Sam = 6
Time taken to read these pages = 18 minutes
Rate at which Sam is reading the pages of the book = [tex]\frac{\text{Number of pages read}}{\text{Time taken to read these pages}}[/tex]
= [tex]\frac{6}{18}[/tex]
= [tex]\frac{1}{3}[/tex] pages per minute
Number of pages read in 126 minutes = Rate of reading × Time
= [tex]\frac{1}{3}\times 126[/tex]
= 42 pages
Therefore, Sam will finish 42 pages in 126 minutes.

if a car driver fills 10 1/2kg of cng and paid rs 1995 what is cost of 1kg of cng
answer quick pls
Given:
A car driver fills [tex]10\dfrac{1}{2}\text{ kg}[/tex] of CNG and paid Rs. 1995.
To find:
The cost of 1 kg of CNG.
Solution:
According to the given information,
The cost of [tex]10\dfrac{1}{2}\text{ kg}[/tex] of CNG = 1995 rupees
Using this information, we get
The cost of 1 kg of CNG = [tex]\dfrac{1995}{10\dfrac{1}{2}}[/tex] rupees
= [tex]\dfrac{1995}{\dfrac{20+1}{2}}[/tex] rupees
= [tex]\dfrac{1995}{\dfrac{21}{2}}[/tex] rupees
= [tex]1995\times \dfrac{2}{21}[/tex] rupees
= [tex]190[/tex] rupees
Therefore, the cost of 1 kg of CNG is 190 rupees.
Dana bought almonds at $8 per can and cashews at $12 per can. In total she bought 470 cans of nuts. Her total bill was $4260. How many cans of each type of nut did she buy? Use either substitution or elimination to solve this problem.
Answer:
almonds =345, cashews=125
Step-by-step explanation:
a=almonds, c=cashews
8a+12c=4260. Equation 1
a + c= 470 Equation 2
a=470-c. Isolate a from equation 2
8(470-c)+12c=4260 sub value of a from equation 2 into equation 1
3760-8c+12c=4260
4c=500
c=125
solve for a by substituting value of c into either equation
a+c=470
a+125=470
a=345

Find the area. Round to the nearest hundredths if necessary.
Answer:
12.25π + 77, or approximately 114.48.
Step-by-step explanation:
We can divide the figure into two semicircles (which equal to one circle) and a rectangle. We know that the diameter of the circles is 7, which means the radius is 3.5. Since all points on the circle are equidistant from the center point, we can subtract 18 - 3.5 - 3.5 = 11. Therefore, the dimensions of the rectangle are 11 x 7, which means the area of the rectangle is 77. The formula for the area of a circle is πr^2. There are two semicircles, which means the sum of them both will equal one circle, since they have the same radius. The sum of the areas of the two semicircles equate to 12.25π. The area of the figure is 12.25 + 77, or approximately 114.48.

Carlos makes a fruit drink by mixing orange juice and grapefruit juice. The ratio of orange juice to grapefruit juice is 3: 1. He makes 10 litres of the fruit drink.
Work out how much orange juice he uses.
Answer:
7.5 litres
Step-by-step explanation:
Let the amount of orange juice ve 3x litres and amount of grapefruit juice be 1x. (As they are in ratio of 3:1.)
Now, according to the question,
He makes 10 litres of the fruit drink.So,
⇒ Amount of orange juice + Amount of grape fruit juice = 10 litres
⇒ 3x + x = 10
⇒ 4x = 10
⇒ x = 10 ÷ 4
⇒ x = 2.5
Now,
⇒ Amount of orange juice he used= 3x litres
⇒ Amount of orange juice he used= 3(2.5) litres
⇒ Amount of orange juice he used= 7.5 litres
∴ He used 7.5 litres of orange juice.

Ayuda porfas!! Una floricola exporta 35 cajas grandes, cada una con 35 paquetes y cada paquete con 35 rosas. ¿Cuantas rosas exporta en total? El problema es de relacion de las potencias cubicas con volumenes.
Answer:
42875
Step-by-step explanation:
because I would have 35 roses in each package
35 x 35= 1225
1225 would be multiplied by the 35 boxes
1225 x 35 = 42875
solve the system of equations below
2x-12y=4
x+12y = 56
Write answer as an ordered pair
Answer:
x = 20
y = 3
Step-by-step explanation:
2x - 12y + x + 12y = 4 + 56
3x = 4 + 56
3x = 60
3x ÷ 3 = 60 ÷ 3
x = 20
x + 12y = 56
20 + 12y = 56
20 - 20 + 12y = 56 - 20
12y = 36
12y ÷ 12 = 36 ÷ 12
y = 3

solve the equation 4^y = 8
Answer:
y = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
4 = 2² and 8 = 2³ , then
[tex]4^{y}[/tex] = 8, can be written
[tex](2^2)^{y}[/tex] = 2³
[tex]2^{2y}[/tex] = 2³
Since bases on both sides are equal, both 2, then equate exponents
2y = 3 ( divide both sides by 2 )
y = [tex]\frac{3}{2}[/tex]
y = 1.5
Step-by-step explanation:
[tex] {4}^{y} = 8[/tex]
Take the logarithm of both sides and you will get
[tex] \log {4}^{y} = y \log4 = \log8[/tex]
or
[tex]y = \frac{\log8}{ \log4} = 1.5[/tex]

What is the area of a triangle whose sides are 15 cm, 8 cm and 19 cm?
Please help?? I have an exam tomorrow
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
x² - 5xy + 6y² = x² - 3xy - 2xy + 6y²
= x(x - 3y) - 2y(x - 3y)
= (x - 3y)(x -2y)
x² - 4xy + 3y² = x² -xy - 3xy + 3y²
= x(x - y) - 3y(x - y)
= (x - y)(x - 3y)
x² - 3xy + 2y² = x² - xy - 2xy + 2y²
= x(x - y) - 2y(x - y)
= (x - y)(x - 2y)
Least common denominator = (x-y)(x - 2y)(x - 3y)
[tex]RHS = \frac{1*(x-y)}{(x-3y)(x-2y)*(x-y)}+\frac{a*(x-2y)}{(x-y)(x-3y)*(x-2y)}+\frac{1*(x-3y)}{(x-y)(x-2y)*(z-3y)}\\\\= \frac{x- y + ax - 2ay +x -3y}{(x-y)(x-2y)(x-3y)}\\\\= \frac{2x -4y +ax - 2ay}{ x^{3}-5x^{2}y+8xy^{2}-4y^{3}}[/tex]
Rearrange so that there is no zero or negative exponent. 2m^0 n^-4
Answer:
2/n^4
Step-by-step explanation:
Anything to the zero power will become 1 so the m^0 will be 1 and that leaves just 2 in its place. Anything to a negative exponent is equal to its reciprocal so n^-1= 1/n^4. Then you multiple what remains, (2 x 1/n^4) to get the above answer.
Answer:
Step-by-step explanation:
2m^0*n^-4
=2*1*1/n^4
=2/n^4
Note:Any base that has it's power 0 is always considered as one .
If any base has negative exponent transfer that pase to the denominator then its power will be positive. For exanple:
4^-x
