Step-by-step explanation:
x = 19 19 × 4 = 76 76 + 36 = 112
19 × 6 = 114 114 - 2 = 112
112 + 112 = 224 360 - 224 = 136 136 ÷ 2 = 68 therefore the answer is 68

Answer:
a = √5
b ∈ (−∞,∞)
Step-by-step explanation:
(7 + 3√5)/(3 + √5) - (7 - 3√5)/(3 - √5) = a + b√5
⇔ (7 + 3√5)(3 - √5)/(3 + √5)(3 -√5) - (7 - 3√5)(3 + √5)/(3 + √5)(3 -√5) = a + b√5
⇔ (7 + 3√5)(3 - √5) - (7 - 3√5)(3 + √5)/(3 + √5)(3 -√5) = a + b√5
⇔ 4√5/4 = a + b√5
⇔ √5 = a + b√5
⇔ b = (5 - a√5)/5
Replace b with (5 - a√5)/5
⇒ a + (5 - a√5)/5 = √5
⇔ a × 5 + (5 - a√5)(5)/5 = √5 × 5
⇔ a × 5 + 5 - a√5 = 5√5
⇔ a × 5 - √5 × a = 5√5 - 5
⇔ a(5 - √5) = 5√5 - 5
⇔ a = √5
Given ABCD as marked, what additional information would help you to prove that ABCD is a square? Pls I rlly need help
9514 1404 393
Answer:
a. AC ≅ BD
Step-by-step explanation:
All four sides are marked as being the same length. This means the figure is a parallelogram and a rhombus.
Diagonals bisect each other in any parallelogram. They are perpendicular, and bisect the corner angles, in any rhombus. Choices b, c, and d add no new information.
In order to show the figure is a square, you must show this rhombus is a rectangle: the diagonals must be the same length. That is you must show ...
AC ≅ BD
_____
Additional comment
You may be given problems with coordinates, and asked to show the figure is a parallelogram, rectangle, rhombus, or square. Often, the problem is given with the intent that you use slope and length formulas on the given points to prove opposite sides are parallel and the same length. IMO, these problems are much simpler if you show the appropriate relation exists between the midpoints, slopes, and lengths of the diagonals.

Landon is building new bookshelves for his bookstore's new mystery section. Each shelf can hold 36 books. There are 1,188 mystery books.
Answer:
33 bookshelves
Step-by-step explanation:

If there are 1,188 books, and each shelf can hold 36 books, we need to divide.

What is the domain of the following relation? {(-3, -8), (-2, 9), (1, -1), (5, 3)}
Answer:
Domain:
{−3,−2,1,5}
Step-by-step explanation:
The domain of the given relation is {-3, -2, 1, 5} of the following relation {(-3, -8), (-2, 9), (1, -1), (5, 3)}
The domain of a relation refers to the set of all possible input values or x-values in the relation. In the given relation {(-3, -8), (-2, 9), (1, -1), (5, 3)}, the x-values or the first components of each ordered pair represent the domain.
The domain of a relation is the set of all possible input values or x-values for which the relation is defined. It represents the range of values that can be used as inputs to the relation to obtain corresponding outputs. In other words, the domain is the set of values that the independent variable can take in the relation.
Therefore, the domain of the given relation is {-3, -2, 1, 5}.

Step-by-step explanation:
A rectangular prism is made of 81 unit cubes. The prism is 9 unit cubes long.
Choose two sets of numbers that could be the width and the height of the rectangular prism.
A width: 3 unit cubes
height 3 unit cubes
Width 6 unit cubes
height 12 unit cubes
Cwidth: unit cubes
height 7 unit cube
width: 18 unit cubes
height 4 unit cubes
OE with 24 unit cubes
height 3 unit cubes
Answer:
A width: 3 unit cubes
height 3 unit cubes
Step-by-step explanation:
Volume of rectangular prism = 81 unit cubes
[tex]l[/tex] = Length of rectangular prism = 9 unit cubes
[tex]w[/tex] = Width of rectangular prism
[tex]h[/tex] = Height of rectangular prism
Volume of a rectangular prism is given by
[tex]V=lwh\\\Rightarrow 81=9wh\\\Rightarrow wh=\dfrac{81}{9}\\\Rightarrow wh=9[/tex]
The product of width and height must be 9 so from the options this is only possible when width and height both are 3 units.
So, the width is 3 unit cubes and the height is 3 unit cubes.

2 After a hailstorm, a large car dealership wants to determine the proportion of cars that have damage. The service department randomly selects 50 cars on the dealership lot, examines them, and finds that 11 cars have damage. They want to construct a 99% confidence interval for the true proportion of cars with damage from the storm. Are the conditions for inference met? O Yes, the conditions for inference are met No, the 10% condition is not met No, the randomness condition is not met No, the Large Counts Condition is not met.
Answer:
Yes, the conditions for inference are met
Step-by-step explanation:
Conditions for inference:
To build a confidence interval for a population proportion, the sample must have at least 10 successes and 10 failures.
In this question:
50 cars, 11 have damage and 50 - 11 = 39 do not.
Since both the number of sucesses and of failures is above 10, conditions for inference are met.

You can afford monthly deposits of $250 into an account that pays 4.8% compounded
monthly. How long will it be until you have $11,900 to buy a boat?
Att
Answer:
Step-by-step explanation:
The formula you need for this is
[tex]A(t)=P(1+\frac{r}{n})^{nt[/tex] where
A(t) is the amount after a certain number of years has gone by,
P is the initial deposit,
r is the interest rate in decimal form,
n is the number of compoundings done per year, and
t is the amount of time in years.
For us,
A(t) = 11900
P is 250
r is .048
n is 12 (there are 12 months in a year)
t is our unknown. Filling in:
[tex]11900=250(1+\frac{.048}{12})^{(12)(t)[/tex] which simplifies a bit to
[tex]11900=250(1_.004)^{(12t)[/tex] . Now we'll divide both sides by 250:
[tex]47.6=(1.004)^{12t[/tex] and then take the natural log of both sides to bring that t down out front:
[tex]ln(47.6)=ln(1.004)^{12t[/tex] and then
ln(47.6) = 12t ln(1.004). Now divide both sides by ln(1.004) to isolate the 12t:
967.6383216 = 12t and divide both sides by `12 to get
t = 80.6 months which is 6.7 years
In 2005, the population of a state was 31,006,000. If the population grows at 1.2% per year, approximately how
many years (from 2005) will it take the population to reach 40,000,000? (Assuming it grows at the same rate)
use the continuous growth function:
A=pen
150 years
249 years
21 years
26 years
Answer:
Step-by-step explanation:
Population of the state will reach 40,000,000 in 21 years from year 2005.
Option (3) will be the correct option.
Exponential growth of the poulation: Exponential growth for the population growth is given by the expression,
F = I(1 + r)ⁿ
Here, F = Final population
I = Initial population
r = Growth rate
n = Number of years for population growth
Given in the question,
Initial population = 31006000Growth rate = 1.2%Final population = 40000000To find the number of years for population growth, substitute the values,
F = I(1 + r)ⁿ
40000000 = 31006000(1 + 0.012)ⁿ
40000 = 31006(1.012)ⁿ
[tex](1.012)^n=\frac{40000}{31006}[/tex]
[tex]\text{log}(1.012)^n=\text{log}(1.29)[/tex]
nlog(1.012) = log(1.29)
0.00518n = 0.11059
n = [tex]\frac{0.11059}{0.00518}[/tex]
n = 21.34
n ≈ 21 years
Therefore, population of the state will reach 40,000,000 in 21 years from 2005. Option (3) will be the answer.

The shorter leg of a right triangle is 2 feet shorter than the longer leg. The hypotenuse is 10 feet. How long is each leg?
a=shorter leg
b=longer leg
c=hypotenuse
a=b-14
c^2=a^2+b^2
26^2=(b-14)^2+b^2
676=b^2-2*b*14+14^2+b^2
676=2b^2-28b+196
676-196=2(b^2-14b)
480=2(b^2-14b) Divide with 2
240=b^2-14b
b^2-14b=240
b^2-14b+7^2=240+7^2
Becouse: (b-7)^2=b^2-14b+7^2
(b-7)^2=240+49
(b-7)^2=289
b-7=sqroot(289)
You have two solutions:
b-7=17 and
b-7=-17
Becouse sqroot(289)=+/- 17
First solution: b-7=17
b=17+7=24
Second solution:
b-7=-17
b=17+7=-10
leg of triangle can not be negative number so:
b=24

Cuánto tarda un vehículo en recorrer 26 km con una velocidad constante de100km/h
Answer:
Un vehículo tardará 15 minutos y 36 segundos en recorrer 26 km con una velocidad constante de 100km/h.
Step-by-step explanation:
Para determinar cuánto tarda un vehículo en recorrer 26 km con una velocidad constante de 100km/h se deben realizar los siguientes cálculos:
(26/100) x 60 = X
0.26 x 60 = X
15.6 = X
1 = 60
0.6 = X
0.6 x 60 = X
36 = X
Por lo tanto, un vehículo tardará 15 minutos y 36 segundos en recorrer 26 km con una velocidad constante de 100km/h.
