Locate the digit to the right of the place you're rounding to. If that digit is 5 or more, add 1 to the digit in the place you're rounding to. Drop all digits to the right of the one you're rounding to, unless it is left of the decimal point. In that case, zero any digits between the one you rounded and the decimal point. (See problem 3 for an example of this.)
If you're rounding to the ones place (nearest whole number), and that digit ends up being 0, then put a decimal point after it to indicate it is a significant digit.
The second attachment shows the names of the number places, if you need a reminder.

x= 33
Step-by-step explanation:
The sum of the angles on a straight line is 180°. This is abbreviated as 'adj. ∠s on a str. line'.
104° +x° +(x +10)°= 180°
2x° +114°= 180°
2x°= 180° -114°
2x°= 66°
Divide both sides by 2:
x°= 66° ÷2
x°= 33°
x= 33

A random sample of size 32 is selected from population X, and a random sample of size 43 is selected from population Y. A 90 percent confidence interval to estimate the difference in means is given as (−1.25,0.87)
.
Consider a change in the sample sizes such that a random sample of size 52 is selected from population X and a random sample of size 63 is selected from population Y. When all other things remain the same, what effect would such a change have on the interval?
Answer:
The level of confidence will increase.
Step-by-step explanation:
Could be wrong
The change in the sample size will lead to a decrease in the width of the interval.
What is a sample size?A sample size simply means the number of subjects that are taken from the population for research.
In this case, increasing the sample size will decrease the standard error and therefore, the width of the confidence interval will reduce.
Therefore, as the sample size increases, the interval reduces.

Recipe A:Cups of flour used = 3
Rolls made = 12
Cups of flour per roll

Suppose you are making a sail in the shape of a right triangle for a sailboat. The length of the longest side of the sail is 65 ft. The sail is to be 63 ft high. What is the length, in feet, of the third side of the sail?
Answer:
in right angled triangle ABC
hypotenuse [h]=65ft
base[b]=xft
height[p]=63ft
by using Pythagoras law
h²=p²+b²
65²=63²+x²
x²=65²-63²
x=√256
x=16feet
so the third side of the sail is 16ft.
Base:-
√H²-P²√65²-63²√16²16ftOn a map,the scale shown is 1inch:5miles.If an island is 75 square inches on the map,what is the actual area of the island?

Uptown’s competitor, Downtown Cable, charges each customer $60 for installation, plus $35 per month for cable programming.

Answer:
B) Six Months.
Step-by-step explanation:
We can write an equation to model each situtation.
Let m be the number of months and c be its total cost.
Uptown Cable charges $120 for the initial installation fee plus $25 per month. In other words, its total cost is:
[tex]c=120+25m[/tex]
Downtown Cable charges an initial $60 fee plus $35 per month. So:
[tex]c=60+35m[/tex]
To find after how many months will the two services remain the same, we can set the two equations equal to each other and solve for m. So:
[tex]120+25m=60+35m[/tex]
Solve for m:
[tex]60=10m\Rightarrow m=6[/tex]
The two cable companies will charge the same after six months of use.
Notes:
If the customer uses the service for less than six months, then Downtown Cable is better since its initial cost is lower.
If the customer uses the service for more than six months, then Uptown Cable is better since its rate per month is lower.

How do I find the point of intersection?
Answer:
(-1 3/5, 2 3/5)
Step-by-step explanation:
Red Line:
m = 3-(-1)/-2-2 = 4/-4 = -1
b = 1
equation: y = -x + 1
Blue Line:
m = 5-1/2-(-4) = 4/6 = 2/3
find 'b':
5 = 2(2/3) + b
15/3 = 4/3 + b
b = 11/3
equation: y = 2/3x + 11/3
Find Point of Intersection:
-x + 1 = 2/3x + 11/3
multiply each side by 3 to get:
-3x + 3 = 2x + 11
-5x = 8
x = -8/5
find 'y':
y = -(-8/5) + 1
y = 8/5 + 1 = 13/5
y = 2 3/5

Suppose that an individual has a body fat percentage of 19.3% and weighs 187 pounds. How many pounds of her weight is made up of fat? Round your answer
to the nearest tenth.
Answer:
The individual has 36.09 pounds of body fat.
Step-by-step explanation:
Given that an individual has a body fat percentage of 19.3% and weighs 187 pounds, to determine how many pounds of her weight is made up of fat the following calculation must be performed:
(187 x 19.3) / 100 = X
3.609.1 / 100 = X
36.091 = X
Therefore, the individual has 36.09 pounds of body fat.
Karina deposito S/. 3000 en un banco en un banco a una tasa de interes simple del 2% mensual ¿Cuánto ganara en dos años
Answer:
En dos años ganará S/. 4440.
Step-by-step explanation:
Puedes encontrar la respuesta utilizando la fórmula para calcular el valor futuro:
VF=VP*(1+(i*n))
VP= valor presente= 3000
i= tasa de interés= 0.02
n= número de periodos de tiempo= 24 meses (2 años corresponden a 24 meses)
VF=3000*(1+(0.02*24))
VF=3000*(1+0.48)
VF=3000*1.48
VF=4440
De acuerdo a esto, la respuesta es que en dos años ganará S/. 4440.
What is the difference between an inscribed angle and a central angle?
Answer/Step-by-step explanation:
An inscribed angle is an angle that is formed by two chords in a circle. The vertex of an inscribed angle is at any point on the circumference of the circle.
On the other hand, a central angle is an angle that is formed by two radii of a circle. The vertex of a central angle is at the centerbof a circle.
Thus, from the diagram attached below, <EFG is an inscribed angle while <EOG is the central angle of the circle O.
Inscribed angle = ½ of the central angle.
hamid has gained weight.
he now weighs 88kg which is 10% higher than his normal weight
what is hamids normal weight?
Answer:
8.8 kilograms
Step-by-step explanation:
Answer: 83.6 Kg
Step-by-step explanation:
x * 0.1 = y ---> x = y/0.1
88 - y = x
y/0.1 = 88 - y
2y = 88 * 0.1
y = 4.4
88 - 4.4 = 83.6Kg
