Step-by-step explanation:
2×{(6+12)=(3+1)}-1
We will have to solve the ones in the bracket first.
2×{(18)=(3+1)}-1
2×{18=4}-1
So now we remove the brackets
2×18=4-1
36=3
Then we divide both sides by 3
So the final answer is 12
- 1 13 and its opposite on a number line.
Answer:
-113 and 113
Step-by-step explanation:
I'm not sure exactly what you mean by -1 13, so I'll assume you mean -113.
It's opposite would be 113.
If what you mean is -1 1/3 then it would be -4/3

you get paid $8 an hour. you make $35 in tips. you make $167.00 in a week. how many hours did you work. write an equation to the problem.
Answer:
I belive the equation would be...
Step-by-step explanation:
8x+$35=$167.00
Hope it helps??
Answer
they worked 16.5 hours that week.
Step-by-step explanation:
You first subtract the tip by the total cost and that gives you $132.00. and from that cost you divide by $8 which they get paid by the hour... and then you get the 16.5 and that means they worked 16.5 hours that week.

(-5, 10) and (5, -10)
a. y = 2x -10
b. y = 2x
c. y = -2× + 20
d. y = -2×
Answer:
d. y = -2×
Step-by-step explanation:
First to solve find the slope using the formula, [tex]\frac{10+10}{-5-5}[/tex]. The slope equals 20/-10 or -2. Then plug the slope and point, (-5,10), into slope-point form. y-10=-2(x+5), then solve for y. This gives you y=-2x+0 or y=-2x.

Answer:
y ≈ 12.3
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationship between trig functions and side of a right triangle. In particular, when the adjacent side and hypotenuse are involved, the desired relation is ...
Cos = Adjacent/Hypotenuse
cos(35°) = y/15
y = 15·cos(35°)
y ≈ 12.3

Which ordered pair is a solution to the inequality 7x-3y>10?
it ain't possible.
unless Either X's value is given for u to get y.
All pairs such that x is > 4 and y = 6 are solutions.
It is given that ordered pair is a solution to the inequality 7x-3y>10.
What is inequality?
The definition of inequality is a difference in size, amount, quality, social position or other factor.
Now, characterize these solutions
if 7x - 3y > 10 then
7x > 10 +3y
Now we can substitute any value for y and get the appropriate value for x. For example I can choose y to be 6
then by substitution
7 must be > 10+ 3*6
or 7x must be > 28
or x must be > 4
So, all pairs such that x is > 4 and y = 6 are solutions.

Re(z)=
Im(z)=
9514 1404 393
Answer:
Re(z) = -19Im(z) = -24Step-by-step explanation:
There is some disagreement over whether the "imaginary part" includes the factor "i" or not. Here, we assume it is simply the coefficient of i.
Re(z) = -19 . . . . the part that does not have a factor of i
Im(z) = -24 . . . . the coefficient of i
Find the length of the segment with endpoints A(4,12) and B(7,16) ?
Why is the ? in the proportion below equal to QR? Explain why.
A) SQ is the geometric mean between the hypotenuse and the closest adjacent segment of the hypotenuse.
B) SQ is the shortest leg and so is the geometric mean between the entire leg and the hypotenuse.
C) SQ is the hypotenuse and is opposite the angle S in the right triangle QSR.
D) SQ is the hypotenuse and thus the Hypotenuse Rule of Geometric Means applies.
9514 1404 393
Answer:
A) SQ is the geometric mean between the hypotenuse and the closest adjacent segment of the hypotenuse.
Step-by-step explanation:
In this geometry, all of the right triangles are similar. That means corresponding sides have the same ratio (are proportional).
Here, SQ is the hypotenuse of ΔSQT and the short side of ΔRQS.
Those two triangles are similar, so we can write ...
(short side)/(hypotenuse) = QT/SQ = QS/RQ
In the above proportion, we have used the vertices in the same order they appear in the similarity statement (ΔSQT ~ ΔRQS). Of course, the names can have the vertices reversed:
QT/SQ = SQ/QR . . . . . QS = SQ, RQ = QR
__
When this is rewritten to solve for SQ, we get ...
SQ² = QR·QT
SQ = √(QR·QT) . . . . SQ (short side) is the geometric mean of the hypotenuse and the short segment.

Tom is going to the fair in town and wants to eat lunch. A hot dog costs 2$ and a cheeseburger costs 3$.write an equation that represents the possible combinations of how many of each he can buy for 10$
Answer:
Let's define the variables:
x = number of hot dogs he buys
y = number of cheeseburgers he buys.
Each hot dog costs $2, then the price of x hotdogs is:
x*$2
Each cheeseburger costs $3, then the price of y cheeseburgers is:
y*$3
The total price is:
x*$2 + y*$3
And we want to find an equation to see how much he can buy for exactly $10, then we have:
x*$2 + y*$3 = $10
Or, if he can use $10 or less than $10, the inequality would be:
$0 ≤ x*$2 + y*$3 ≤ $10

Suppose you obtained a Spearman rs of 0.53 from a sample of 13 pairs of scores. For a two-tailed test, such a correlation coefficient is:_____
a. not statistically signficant
b. p <.001
c. p < .01
d. p < .05
Answer:
C: p < 0.01
Step-by-step explanation:
We are given;
Spearman rank Correlation Coefficient: rs = 0.53
sample size: n = 13 pairs
Now, from the table attached, tracing n = 13 and locating a corresponding value of rs = 0.53 which falls in between 0.484 and 0.56. Thus, we can see that p is greater than the nominal significance value of 0.05 but less than 0.01.
Thus, correct answer is p < 0.01
Find the domain of the function f(t)=√t +3√t
Answer:
[tex]\mathrm{Domain\:of\:}\:4\sqrt{t}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:t\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]
The graph is also attached below.
Step-by-step explanation:
Given the expression
[tex]f\left(t\right)=\sqrt{t}\:+3\sqrt{t}[/tex]
We know that the domain of a function is the set of inputs or argument values for which the function is real and defined.
We know that we can not have a negative value of 't' inside the radicals because if we put any negative number inside the radical expression, it would make the function undefined.
In other words, the value of t ≥ 0.
Therefore, the function domain is:
[tex]\mathrm{Domain\:of\:}\:4\sqrt{t}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:t\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]

Ms Patel purchased some pliers, wrenches, and chisel sets for her shop. She bought twice as many pliers that cost $17.50 each as wrenches that cost $21.50 each. She bought 3 fewer chisel sets than pliers. How many of each tool did Ms Patel buy if she paid a total of $141 and the price of each chisel set is $28?
Ms Patel bought 4 pliers, 2 wrenches and 1 plier set.
Step-by-step explanation:First, make a ratio. For every 2 wrenches, she bought 4 pliers and 1 chisel set. This ratio would be written as (in pliers:wrenches:chisels)4:2:1
Then, multiply each of these numbers by their price, and add them together.PLIERS: 4 × 17.50 = $70
WRENCHES: 2 × 21.50 = $43
CHISEL SETS: 1 x 28 = $28
TOTAL = $70 + $43 + $28 = $141
As this adds up to $141, this shows that she bought 4 pliers, 2 wrenches and 1 chisel set.Mrs Patel purchased 2 wrenches, 4 pliers, and 1 chisel set for her shop.

The temperature at the point (x, y, z) in space is given by T ( x, y, z) = x + yz. A fly is at the point (1, 2, 1). In what direction should he begin to fly to cool off as quickly as possible. Your answer should be a unit vector in the requested direction.
Answer:
[tex]u= -\frac{1}{\sqrt{6}} ,-\frac{1}{\sqrt{6}} ,-\frac{2}{\sqrt{6}}[/tex]
Step-by-step explanation:
From the question we are told that
Temperature is given [tex]T ( x, y, z) = x + yz.[/tex]\
A fly is at (1,2,1)
Generally the direction of fly is given by
[tex]\triangleT(x,y,z) =(1,z,y)\\[/tex]
[tex]v= \triangleT(1,2,1)\\v=(1,1,2)[/tex]
Mathematically solving for the vector direction
[tex]|v|=\sqrt{1^2+1^2+2^2}[/tex]
[tex]|v|=\sqrt{6}[/tex]
[tex]u=- \frac{v}{|v|}[/tex]
[tex]u= -\frac{1}{\sqrt{6}} ,-\frac{1}{\sqrt{6}} ,-\frac{2}{\sqrt{6}}[/tex]
Therefore this the direction which should be taken to cool down soonest

What is 1/5 ÷ 1/2 ? Explain or show your reasoning.
Answer:
The answer is 2/5.
Step-by-step explanation:
First, use the stay-switch-flip method. Keep 1/5 the same, switch the division sign into a multiplication sign, and flip the numerator and the denominator of 1/2 to get 1/5 x 2/1. Multiply the numerators. 1 x 2 = 2. Now, multiply the denominators. 5 x 1 = 5. Therefore, you're answer is 2/5.

Write a conjecture that describes the pattern in the sequence, and then use the conjecture to find the next term in the sequence.
2,8, 32, 128,...
100 words remaining
Answer:
T5 = 512
Step-by-step explanation:
Given the sequence
2,8, 32, 128,...
The sequence is a geometric progression
nth term of a geometric progression is expressed as:
Tn = ar^n-1
a is the first term = 2
n is the number of terms = 5 (next term is the 5th term)
r is the common ratio = 8/2 = 32/8 = 4
Substitute and get the fifth term
T5 = 2(4)^5-1
T5 = 2(4)^4
T5 = 2*256
T5 = 512
Hence the next term is 512
