Answer:
Jamie's estimate is correct, since the result is 2.1% less than the estimated number.
Step-by-step explanation:
Given that Jamie says the value of the expression 1.43 x (19/37) is close to 0.75, to determine if Jamie's estimate seems reasonable the following calculation must be performed:
1.43 x (19/37) = X
1.43 x 0.513 = X
0.7343 = X
0.75 = 100
0.7343 = X
0.7343 x 100 / 0.75 = X
97.9 = X
Therefore, Jamie's estimate is correct, since the result is 2.1% less than the estimated number.

use the graph to answer the questions.
1) Write in standard form
2) Identify the foci and asymptotes
3) find the domain and range
Answer:
Example: Locating a Hyperbola's Vertices and Foci
The hyperbola is centered at the origin, so the vertices serve as the y-intercepts of the graph. To find the vertices, set x=0 x = 0 , and solve for y y . Therefore, the vertices are located at (0,±7) ( 0 , ± 7 ) , and the foci are located at (0,9) ( 0 , 9 ) .

if the sum of interior angles of polygon is 1800
Answer:
12 sides
Step-by-step explanation:
Given
[tex]Sum =1800^o[/tex]
Required
The number of sides of the polygon
The sum of interior is calculated using:
[tex]Sum = 180 * (n - 2)[/tex]
Where
[tex]n \to[/tex] number of sides
So, we have:
[tex]Sum = 180 * (n - 2)[/tex]
[tex]1800 = 180 * (n - 2)[/tex]
Divide both sides by 180
[tex]10 = n - 2[/tex]
Add 2 to both sides
[tex]12= n[/tex]
[tex]n=12[/tex]
Not sure how to make an equation for this problem. The equation I put was 86 - 8 = b x 2 = 156. But, it is starting that is incorrect. How do I go about this problem?
Answer:
b/2 + 8 = 86
b = 156
Step-by-step explanation:
Half the comics is b/2
b/2 + 8 = 86
Subtract 8 from both sides
b/2 = 78
multiply both sides by 2
b = 156

In ΔQRS, the measure of ∠S=90°, RQ = 41, QS = 9, and SR = 40. What is the value of the cosine of ∠R to the nearest hundredth?
Answer:
cos R = .98
Step-by-step explanation:
cos R = SR/QR
QR is the hypotenuse of the right triangle. By the Pythagorean theorem
(QR)^2 = (QS)^2 + (SR)^2
= 9^2 + 40^2
= 81 + 1600
= 1681
QR = 41
Cos R = adjacent side/hypotenuse = 40/41 = .98
The value of the cosine of ∠R to the nearest hundreth is 0.98.
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
The sides can also be found using pythagoras theorem. Therefore,
∠S = 90°
RQ = 41
QS = 9
SR = 40
cos R = adjacent / hypotenuse
Therefore,
adjacent side = 40
hypotenuse = 41
cos R = 40 / 41
cos R = 0.97560975609
cos R = 0.98

Teresa deposits $800 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in the first 2 years?
Answer:
I'll setup the problem and you can do the computation
Step-by-step explanation:
The formula for simple interest:
I = P*r*t
I = interest
P = deposit
r = interest rate per period
t = number of periods
P = $800
r = 0.02
t = 2

The area of a trapezoid is given by
A = 1/2 ( b1+b2) h where b1 and b2 are the lengths of the bases and h is the height
We need to change 1 1/4 ft to inches = 1.25 (12) = 15 inches

A recent study indicated that the average cost of living for a family of four in various cities across the US was $65,351 with a standard deviation of $7712. A company is thinking about relocating to a city with a lower cost of living. They would like to choose a city in the bottom 30% of those surveyed. What is the cutoff for the cost of living that would make a city eligible for relocation by this company
Answer:
The correct answer is "57408".
Step-by-step explanation:
Given:
[tex]\mu=65351[/tex]
[tex]\sigma=7712[/tex]
[tex]p=0.15[/tex]
As per the standard table, we know,
[tex]z=-1.03[/tex]
Now,
⇒ [tex]z=\frac{x-\mu}{\sigma}[/tex]
By putting the values, we get
[tex]-1.03=\frac{x-65351}{7712}[/tex]
[tex]x=57407.64[/tex]
or,

A train can travel 360 miles in 4 hours. How much time will it take
travelling 585 miles?
Answer:
6.5 hours
Step-by-step explanation:
We can write a ratio to solve
360 miles 585 miles
---------------- = ------------
4 hours x hours
Using cross products
360 * x = 4* 585
360 x = 2340
Divide each side by 360
x = 2340/360
x =6.5

Answer:
B. 66 m
Step-by-step explanation:
Map and ground distances are proportional:
ground/map = ground/(12 cm) = (11 m)/(2 cm)
ground = (12 cm)(11 m/(2 cm)) = 66 m
The distance from A to B is 66 m.

If f(x)= (3+x)/(x-3) what is the f(a+2)
Answer:
f(a + 2) = (5 + a) / (a - 1)
Step-by-step explanation:
To answer items such as this, we directly substitute the a + 2 to the all the x's in the function such that,
f(a + 2) = (3 + a + 2) / (a + 2 - 3)
Simplifying the function generated above,
f(a + 2) = (5 + a) / (a - 1)
Sonia ran 6 miles more than twice as far as Brian if the total number of milesso you ran 6 miles more than twice as far as Brian if the total numbers of Miles run by both is 33 how far did each one run.
Answer: Brian ran 9 miles
Sonia ran 24 miles
Step-by-step explanation:
Let's Brian's distance be represented by x.
Since Sonia ran 6 miles more than twice as far as Brian. This will be:
= (2 × x) + 6
= 2x + 6
Therefore,
x + 2x+6 = 33
3x + 6 = 33
3x = 33 - 6.
3x = 27
x = 27/3
x = 9
Brian ran 9 miles
Sonia ran = 2x+6 = 2(9).+ 6 = 18+6 = 24 miles
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
A) (x, y) → (x + 5, y – 3)
B) (x, y) → (x + 5, y + 3)
C) (x, y) → (x – 3, y + 5)
D) (x, y) → (x + 3, y + 5)
Answer:
C
Step-by-step explanation:
Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is [tex]y + 5[/tex].
Moving left or right affects the "x" coordinate and moving left is negative so
[tex]x - 3[/tex]
[tex](x - 3, y + 5)[/tex]
Hence, C is the correct answer

Can it make a triangle? Explain why?

Answer:
yes, yes, no; No
Step-by-step explanation:
We have to assume you have no trouble with single-digit addition and comparison of two numbers.
3+4 > 1 ⇒ 7 > 1 . . . . yes
4+1 > 3 ⇒ 5 > 3 . . . . yes
3+1 > 4 ⇒ 4 > 4 . . . . no
These lengths will not make a triangle because the triangle inequality is not satisfied.

Additional comment
You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.

Another sponsor will donate $12 for each mile she walks. How many miles should she walk if she
wants to raise exactly $200 from those two sponsors? )
Let m represent the number of miles Dalaysia walks. Write an equation that
represents the number of miles Dalaysia needs to walk to raise exactly $200 from
the two sponsors. 1)
Answer:
10 miles to earn 200 cash
Steps:
80 + 12m = 200
12m = 200 - 80
12m = 120
12m/12 = 120/12
m = 10
Answer:
200 = 80+12m
10 miles
Step-by-step explanation:
She will get 80 from the first and 12m from the second
She needs 200
200 = 80+12m
Subtract 80 from each side
200 -80 = 12m
120 = 12m
Divide each side by 12
120/12 = m
10 =m
She needs to walk 10 miles

Step-by-step explanation:
The quadrilateral is a parallelogram
The area of a parallelogram can simply be calculated by multiplying the base length by the height
The parallelogram has a height of 3m and a base length of 4 + 10 = 14m
Hence area = 14 * 3 = 42
PLEASE HELP ME FIND THE AREA
Answer:
20m^2 or 20m squared
Step-by-step explanation:
a triangle's area is calculated by the formula hb/2 or height x base/2
in this triangle the height is 8m, and the base is 5m
therefore, the area is 8(5)/2 = 40/2 = 20
20m^2
