Answer:
n > -5Step-by-step explanation:
Solve inequality:
-105 < -7(5 - 2n)-15 < -(5 - 2n)-15 < - 5 + 2n-10 < 2n-5 < nn > - 5Highlight the points to the right from -5
Answer:
[tex]n>-5[/tex]
Step-by-step explanation:
−105<−7(5−2n)
Divide both sides by −7. Since −7 is negative, the inequality direction is changed.
[tex]\frac{-105}{-7}[/tex] > 5−2n
Divide −105 by −7 to get 15.
15>5−2n
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
5−2n<15
Subtract 5 from both sides.
−2n<15−5
Subtract 5 from 15 to get 10.
−2n<10
Divide both sides by −2. Since −2 is negative, the inequality direction is changed.
n>[tex]\frac{10}{-2}[/tex]
Divide 10 by −2 to get −5.
n>−5

-8-4
8-(-4)
-9 + 5
Answer:
-12=-8 -4
-4= -9 +5
4=9+ (-5)
12= 8-(-4)
Step-by-step explanation:
We can drag the numbers to the boxes on the right to match the expressions:
-12 → -8 - 4
-4 → -9 + 5
4 → 9 + (-5)
12 → 8 - (-4)
To match each expression on the left with its numeric equivalent, we can simply evaluate the expressions:
Expressions play a crucial role in human interaction, conveying emotions, intentions, and information without the need for extensive verbal communication. They enrich our conversations and help create deeper connections with others.
-9 + 5 = -4
9 + (-5) = 4
8 - (-4) = 12
-8 - 4 = -12
Now, we can drag the numbers to the boxes on the right to match the expressions:
-12 → -8 - 4
-4 → -9 + 5
4 → 9 + (-5)
12 → 8 - (-4)

which temp is warmer -2 degrees celsius or -5 degrees celsius
Answer:
-2 degree celsius
Step-by-step explanation:
-2 degree celsius
-5 degree celsius
Which is warmer?
__________________
Usually when people try to find a warmer temperature. They look for the biggest number, one that has more value, as in this case, people would tend to say since 5 is bigger than 2, therefore it must be warmer. Wrong. What we're dealing with here is negatives, this goes backwards, the number that is smaller is warmer, following that logic. Which is a warmer temperature?
-5 or -2?
-2 degree celsius

Answer:
The volume of this triangular prism is 20[tex]cm^{3}[/tex]
Step-by-step explanation:
Just like it is shown in the picture we can use the formula for the volume of a triangular prism.
[tex]V = \frac{1}{2}bhl[/tex]
In our case b = 5cm, h = 2 cm, l = 4cm. Now we just plug in the values and get...
[tex]V = \frac{1}{2}bhl\\\\[/tex]
[tex]V = \frac{1}{2}(5)(2)(4)[/tex]
[tex]V = 20cm^{3}[/tex]
Therefore the volume of the triangular prism is 20[tex]cm^{3}[/tex].
Two angles are supplementary. The measure of one angle
is 16 more than two times the measure of the other
angle. How many degrees are in each angle?
Answer:
82 and 98.
Step-by-step explanation:
set up 2 equations
x+y=180
2x+16=180
you start by solving the second equation to find one of the angles.
180-16= 164
2x=164
164÷2= 82
x=82
since you've solved that equation, add in the missing variable to solve for the next one
82+y=180
180-82= 98

Ans should be 133°
Step-by-step explanation:
As we know..
sum of internal angles of a hexagon is 720°
So,
120+130+150+97+90+x=720
solving this we obtain value of x as 133°

Answer:
2/15
Step-by-step explanation:
The given expression for θ can be rewritten to ...
5sin(θ + arctan(-3/4)) = 0
This will have solutions ...
θ +arctan(-3/4) = nπ
θ = nπ - arctan(-3/4) = nπ + arctan(3/4)
__
The corresponding values of sine and cosine will be ...
sin(arctan(3/4)) = 3/5
cos(arctan(3/4) = 4/5
or both values may be negative. Either sign will give the same result in the expression we're to find.
(2sin(θ) -cos(θ))/(sin(θ) +3cos(θ)) = (2(3/5) -(4/5))/(3/5 +3(4/5))
= ((6 -4)/5)/((3+12)/5) = 2/15
[tex]\boxed{\dfrac{2\sin\theta-\cos\theta}{\sin\theta+3\cos\theta}=\dfrac{2}{15}}[/tex]

#8: Ella's grandmother sewed her a change purse. When she gifted it to her, Ella counted 23 coins already in it. Ella noticed there were only dimes and quarters worth $4.70. How many dimes were in the change purse?*
9514 1404 393
Answer:
7 dimes16 quartersStep-by-step explanation:
We can let d represent the number of dimes. Then the number of quarters is 23-d, and the total value of the change is ...
0.10d + 0.25(23 -d) = 4.70
-0.15d + 5.75 = 4.70
1.05 = 0.15d . . . . . . . . add 0.15d -4.70 to both sides
7 = d . . . . . . . . . . . . . . divide by 0.15
There were 7 dimes in the change purse.

There were 23-7 = 16 quarters.

Answer:
Perimeter = 28·√2 + 24 feet
Step-by-step explanation:
The dimensions of the initial sheet of plywood are;
The length of the sheet of plywood = 25 ft.
The width of the sheet of plywood = 14 ft.
The shape cut from each corner of the sheet of plywood = A right triangle
The leg length of each of the cut out right triangles = 7 ft.
The number of leg lengths of the right triangle cut from the length side of the initial sheet of plywood = 2
The length of the parallel sides of the remaining hexagonal piece of plywood = Initial length of the plywood - 2 × The leg length of the cut out right triangle
∴ The length of the parallel sides of the remaining hexagonal piece of plywood = 26 ft. - 2 × 7 ft. = 12 ft.
The other side length of the remaining hexagonal piece of plywood = The hypotenuse side of the cut out right triangle
The hypotenuse side of the cut out right triangle = √((7 ft.)² + (7 ft.)²) = 7·√2 ft.
∴ The other side length of the remaining hexagonal piece of plywood = 7·√2
The number of side lengths in the remaining hexagonal piece of plywood = 4
The perimeter of the remaining hexagonal piece of plywood = 2 × The length of the parallel sides + 4 × The other side lengths
∴ The perimeter of the remaining hexagonal piece of plywood = 2 × 12 ft. + 4 × 7·√2 = (28·√2 + 24) ft.
The perimeter of the remaining hexagonal piece of plywood = (28·√2 + 24) feet
A silo has a radius of 10 meters, like the one shown, and is filled from top to bottom with rice. If rice sells for $75 a cubic meter, what is the total value of rice in this silo?
Answer:
$1500
Step-by-step explanation:
Since the radius of the silo is 10 meters, then the total length of the silo is 20 meters. So now we multiply 75 by 20
75 x 20 = 1500
So the value of the rice in the silo is $1500
