Answer:
[tex]-\frac{1}{21}[/tex]
Step-by-step explanation:
The opposite of -2\3 is 2\3
-
-5\7 + 2\3
Least common multiple of 7 and 3 is 21. Convert -5\7 and 2\3 to fractions with denominator 21.
-
-15\21 + 14\21
Sinse -15\21 and 14\21 have the same denominator, add them by adding their numerators.
[tex]\frac{-15+14}{21}[/tex]
-
Add −15 and 14 to get −1.
-1\21
solve for x : 13x + 7 = -227
Answer:
-18
Step-by-step explanation:
1. Subtract 7 from both sides:
13x = -234
2. Divide 13 from both sides:
13x/13 = -234/13
x = -18

What is the coefficient of the x to the power of 4 y to the power of 3 term in the expansion of (x-2y) the the power of 7?
Answer:
-280
Step-by-step explanation:
step-by-step explanation: so ( x-2y)^7 expanded is: x^7-14 x^6y+84x^5y^2-280x^4y^3+560x^3 y^4-672x^2y^5+448xy^6-128y^7. The x^4y^3 term would then be -280 x^4y^3,meaning the coefficient (the number before the variables) here is 280

the population of rats in nyc is estimated to be 3000000 currently. the rat population is growing by 1% per month. what is the estimated population of rats in 5 years?
Answer:
5,450,000
Step-by-step explanation:
The population can be modeled by an exponential function with a growth rate of 1% per month. The time of interest, 5 years, is 60 months.
__
population = (initial value) × (1 + growth rate per month)^(months)
p = 3,000,000 × (1.01^60) . . . . . . population in 60 months
p ≈ 5,450,000 . . . . in 5 years
The estimated population of rats in nyc is about 5,450,000 in 5 years.

write an equation of a line perpendicular to the line 1/2x - 5 , passing through the point (-1 , 7)
y=-2x+5
Calculations ↓First of all we need to determine the slope of the line perpendicular to y = 1/2x - 5 .
The slopes of perpendicular lines are opposite reciprocals.
So we take 1/2 , turn it over , and change it's sign :
[tex]^1/_2\:\:\:--- > ^2/_1\:\:\:--- > 2\:\:\:--- > -2[/tex]
The slope of the line perpendicular to y = 1/2x-5 is -2 .
Since we're also given a point that the line crosses , we can write the line's equation in point - slope form :
y-y₁=m(x-x₁)
y-7=-2(x-(-1)
y-7=-2(x+1)
Now convert to slope intercept :
y-7=-2x-2
add 7 on both sides :
y = -2x+5[tex]\footnotesize\text{hope\:helpful}[/tex]

The size of the angle QUP in the system formed by the equilateral triangle QUR, the equilateral triangle PUT and the square RUTS is equal to 150°.
How to determine a missing angle within a geometrical system
By Euclidean geometry we know that squares are quadrilaterals with four sides of equal length and four right angles and triangles are equilateral when its three sides have equal length and three angles with a measure of 60°. In addition, a complete revolution has a measure of 360°.
Finally, we must solve the following equation for the angle QUP:
m∠QUR + m∠QUP + m∠PUT + m∠RUT = 360
60 + m∠QUP + 60 + 90 = 360
m∠QUP + 210 = 360
m∠QUP = 150

x = 14
A rectangular prism has a volume of 240 cubic feet. If the length is 4 feet and the width is 4 feet, what is the height of
the prism?
Answer:
Let's use the formula for the volume of a rectangular prism;
V = l · w · h
Where 'l' represents the length, 'w' stands for the width, and 'h' displays as the height. (V evidently stands for the volume)
What we know:
Volume = 240 ftLength = 4 ftWidth = 4 ftWhat we need to find out:
HeightLet's plug in what we know into the formula:
V = l · w · h
240 = 4 · 4 · h
Now let's solve for h:-
240 = 16 · h
240 = 16h
Get rid of h's co-efficient by dividing 16 from both sides because the inverse operation of multiplication(since 16 is being multiplied by h) is division.
÷16 ÷16
Finally, you would end up with a result of:
15 = h
Hence, the height of this prism is 15 feet.

what is the perimeter of 273
Answer:
91
Step-by-step explanation:
given perimeter = 273
perimeter of equilateral triangle = 3a

What is the area of figure abcd? a trapezoid abcd is drawn with length of parallel sides ab and cd equal to 10 inches and 12 inches, respectively. the length of one of the non-parallel sides bc is 6 inches. side bc is perpendicular to dc. a perpendicular line drawn from a to side cd meets cd at e. 54 square inches 60 square inches 66 square inches 72 square inches
Answer: 60 square inches
Step-by-step explanation:
Answer:
66 square inches
Step-by-step explanation:
10 times 6 equals 60 and 60 plus 6 is 66. You add the six because that is the area of the triangle and you get 60 from multiplying 10 and 6 because that is the area of the rectangle.

funar in her famous cookie recipe.
Answer:
203.67
Step-by-step explanation:
all those numbers are confusing, but this is what i get from the picture
triangle area formula = 1/2 base * height
rectangle area formula = L * W
AB = 1/2 base * height, = 1/2 * 9 * 4, = 18
ab is the same as AB =18
C = 8.1 * 4.5 = 36.45
D = 8.1 * 7.2 = 58.32
E = 8.1 * 9 = 72.9
added together = 203.67
