√ 25 –2√3 + √27 +2√ 9 Express in simplified radical
Answer:
The expression in simplified radical form is:
√ 25 –2√3 + √27 +2√ 9 = 11 + √3
Step-by-step explanation:
Given the expression
√ 25 –2√3 + √27 +2√ 9
as
√ 25 = 5
√27 = 3√3
2√9 = 6
so the expression becomes
√ 25 –2√3 + √27 +2√ 9
= 5 - 2√3 + 3√3 + 6
= 11 + √3
Thus, the expression in simplified radical form is:
√ 25 –2√3 + √27 +2√ 9 = 11 + √3
If 24 = 118, what is the measure of each of the other
angles?
Answer:
Step-by-step explanation:
Lines l and m are the parallel lines and line n is a transversal intersecting parallel lines.
Since, m∠2 = m∠4 = 118° [Given]
m∠2 = m∠6 = 118° [Corresponding angles]
m∠4 = m∠8 = 118° [Corresponding angles]
m∠1 + m∠2 = 180° [Linear pair of angles]
m∠1 = 180° - 118° = 62°
m∠1 = m∠5 = 62° [Corresponding angles]
m∠3 = m∠1 = 62° [Corresponding angles]
m∠7 = m∠5 = 62° [Corresponding angles]

how do you use scientific notation to estimate the hours in a year
Answer:
8.760 x 10^3
Step-by-step explanation:
There are 8760 hours in 1 year. So, you can convert this to scientific notation by moving the decimal from 8760 three times to the left: 8760. → 8.760 And since it was moved three times, put an exponent of 3 to the 10: 10^3 So, you get 8.760 x 10^3 hours in a year.
Hope this helps! :)

Step-by-step explanation:
Caleb makes a deposit of $25 in his checking account. His balance after the deposit is $0. He uses a number line to represent the amount of his deposit and his balance before the deposit. Where would the two points be located on the number line? Plot the points on the number line.
Solution :
In the context, it is given that Caleb deposits some amount of money in his checking account. And after the deposit he is having no money in his account i.e. $0 as balance in his account. So he must be his balance as negative in his checking account. Accordingly, before deposit, Caleb had a balance amount of -$25 in his checking account. He deposited $25 to his account, so after the deposit, his balance in the account is $0.
Caleb uses a number line to represent his deposit and the balance before the deposit made.
If the sides of a triangle have the following lengths, find a range of possible values for x.
LM = 6x + 3, MN = 4x - 17, LN = x + 40
Answer:
The range of possible values of x are;
x > 6
Step-by-step explanation:
To form a triangle, the length of two sides must be greater than the third side
Thus;
6x + 3 + 4x-17 > x + 40
6x + 4x-14 > x + 40
10x-14 > x + 40
10x-x > 40 + 14
9x > 54
x > 54/9
x > 6

A painter painted about a fifth of a room in a fifth of a day. Coley estimated the painter would paint 6 rooms in 6 days. Is Coley's estimate reasonable? Complete the explanation.
EXPLANATION: Coley's estimate (is not/is) reasonable because the painter's unit rate is (blank) room per day, so in 6 days the painter would paint about (blank) rooms.
Answer:
yes he is correct
Step-by-step explanation:
if he is painting 1/5 of a room in 1/5 of a day he is painting 1 room in 1 day therefore he can paint 6 rooms in 6 days
An earthquake wave travels through 55 km of rock in 25 seconds . Which equation represents the relationship between t, the number of seconds, and d, the total distance the wave travels?
Answer:
2.2 m/s
Step-by-step explanation:
Step one
Given data
An earthquake wave travels through 55 km
hence distance = 55 km
time taken = 25 seconds
Required
the expression relating t and d
Step two:
we know that velocity is
Speed= distance/time
speed= 55/25
Speed= 2.2 m/s
Janna is looking for an apartment. She plans on paying no more than 25% of her monthly income in rent. If she earns $1,825 a month, which amount represents the most she plans to pay in rent every month?
Answer:
456.25
Step-by-step explanation:
25% as a decimal is .25
To find 25% of her monthly income, multiply 1,825 by .25
1825*.25=$456.25

Which ordered pairs are solutions to the inequality 3x-4y>5
Note: you did not provide the answer options, so I am, in general, solving this query to solve your concept, which anyways would clear your concept.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the inequality
[tex]3x-4y>5[/tex]
All we need is to find any random value of 'x' and then solve the inequality.
For example, putting x=3
[tex]3\left(3\right)-4y>5[/tex]
[tex]9-4y>5[/tex]
[tex]-4y>-4[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}[/tex]
[tex]\left(-4y\right)\left(-1\right)<\left(-4\right)\left(-1\right)[/tex]
[tex]4y<4[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}4[/tex]
[tex]\frac{4y}{4}<\frac{4}{4}[/tex]
[tex]y<1[/tex]
So, at x = 3, the calculation shows that the value of y must be less
than 1 i.e. y<1 in order to be the solution.
Let us take the random y value that is less than 1.
As y=0.9 < 1
so putting y=0.9 in the inequality
[tex]3\left(3\right)-4\left(0.9\right)[/tex]
[tex]=9-3.6[/tex]
[tex]=5.4[/tex]
As 5.4 > 5Means at x=3, and y=0.9, the inequality is satisfied.
Thus, (3, 0.9) is one of the many ordered pairs solutions to the inequality 3x-4y>5.
Write the equation y = mx + b of a line given two points.
Ex 1.(3,3) and (4,-2)
Ex 2. (4,1) and (6,2)
Answer:
Ex 1. y= -5.00x + 18.00 Ex 2. y= 0.50x + -1.00

A car travels 360 miles in 8 hours (with a constant speed). How much time will it take traveling 168 miles?
Answer:
3.7hours
Step-by-step explanation:
Step one:
A car travels 360 miles in 8 hours
the speed is calculated as
speed= distance/time
speed= 360/8
speed= 45mph
Step two:
How much time will it take traveling 168 miles?
having found the speed, which is the rate at which the car is tavelling
time= distance/speed
time= 168/45
time= 3.7hours
