Answer:
w > -1
Step-by-step explanation:
Hello There!
We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations
So we want to get rid of the 8 in 8w
8w is the same as 8 times w (multiplication)
The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8
-8/8 = - 1
8w/8=w
we're left with w > -1

Step-by-step explanation:
Solve the 2x^2 - 5 = 13
Answer:
x=3
x=−3
Step-by-step explanation:
2x^2 - 5 = 13
Subtract 13 from both sides.
2x^2 - 5 - 13 = 0
Subtract 13 from −5 to get −18.
2x^2 - 18 = 0
Divide both sides by 2.
x^2 - 9 = 0
Consider x^2−9. Rewrite x^2−9 as x^2−3^2. The difference of squares can be factored using the rule: a^2−b^2=(a−b)(a+b).
(x−3)(x+3)=0
To find equation solutions, solve x−3=0 and x+3=0.
x=3

Find the midpoint between the two points: (-7, 9) and (5, -1).
A. (18, -23)
B.(11, 4)
C.(13, 18)
D.(1.5, -2)
Answer:
The coordinates of the midpoint between the two
points is (-1,4)
Step-by-step explanation:
Here, we want to find the midpoint between the two given points
To do this, we are to use the midpoint formula
We have this as;
m = (x1 + x2)/2, (y1 + y2)/2
(x1,y1) = (-7,9)
(x2,y2) = (5,-1)
(x,y) = (-7 + 5)/2, (9-1)/2
= (-2/2, 8/2) = (-1,4)
When I have walked 20% of the way to school, I have 1200 metres more to walk than when I have 20% of the walk remaining.
How far, in metres, is it from my home to my school?
Given:
I have walked 20% of the way to school.
I have 1200 metres more to walk than when I have 20% of the walk remaining.
To find:
The distance from home to school.
Solution:
Let x be the distance from home to school.
I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.
It means 1200 is [tex]100\%-20\%-20\%=60\%[/tex] of the total distance from home to school.
[tex]1200=\dfrac{60}{100}x[/tex]
[tex]1200=0.6x[/tex]
[tex]\dfrac{1200}{0.6}=x[/tex]
[tex]2000=x[/tex]
Therefore, the distance from home to school is 2000 metres.
How far, in metres, is it from my home to my school is 2,000 metres.
First step is to formulate
1200/(1-2×20%)
Second step is to find how far in metres
Distance=1200/(1-0.4)
Distance=1200/0.6
Distance=2,000
Inconclusion how far, in metres, is it from my home to my school is 2,000 metres.

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
From the triangle it can be assume that ΔPSR is similar to ΔPQR.
Then, the ratio of corresponding sides of triangles are proportion.

Paul bought a package of 6 spiral notebooks for a total cost of $13.50. Which equation represents p , the cost, in dollars, of each notebook?
Answer:
this is just a hint
Step-by-step explanation:
the question measures 6.EE.7 because it asks the student to solve a real-world problem by writing an equation of the form px=qpx=qpx=q for a case in which p,qp,qp,q and x are all non-negative rational numbers. In this case the equation includes a division expression and shows the total cost of $13.50\$ 13.50$13.50 divided by 666, the number of spiral notebooks.

An aquarium holds 11.39 cubic feet of water, and is 2.3 feet long and 1.8 feet wide. What is its depth? Round your answer to the nearest whole number.
Answer:
2.75feet
Step-by-step explanation:
Given data
Volume= 11.39 cubic feet
Length= 2.3 feet
Width= 1.8 feet
Depth= ???
The expression for the volume is
Volume= Length*Width*depth
11.39=2.3*1.8*d
11.39=4.14d
d= 11.39/4.14
d= 2.75
Hence the depth is 2.75feet
Ashley flies a drone 2,530 ft in 5 s. At this rate how many miles does the drone fly in a minute? 1 mi = 5280 ft
Answer:
I think the answer is 5.75 miles.
Step-by-step explanation:
If the drone flies 2,530 ft in 5 seconds, that means that in one minute it flies 30,360 ft. And 30,360 divided by 5,280 is 5.75.
There are 5.74 miles does the drone fly in a minute.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Ashley flies a drone 2,530 ft in 5 s.
Now,
Since, Ashley flies a drone 2,530 ft in 5 s.
We know that;
1 minute = 60 seconds
Hence, Number of miles in 1 minutes = 2530/5 × 60
= 30,360 ft
Since, We know that;
1 ft = 0.000189 miles
Hence, we get;
⇒ 30360 × 0.000189
⇒ 5.74 miles

14x5=70
then you want to find how many batches to make
70/16=4.375
but you and make 0.375 batches so just make 1 more batch

Answer:
Volume: 762 in³
LA: 448 in²
SA: 544 in²
Step-by-step explanation:
So first, the volume, the formula to find the area is base x height, so we have to find the base first:
8 x 12 ÷ 2 = 48
48 x 14 = 672
So the volume of the prism is 762 in³
Now, the lateral area, which is basically the surface area without the bases, or, in this case, the triangles:
10 x 14 = 140 x 2 = 280
12 x 14 = 168
168 + 280 = 448
So the LA = 448 in²
Now, for the surface area:
12 x 8 = 96 (usually, it would then be ÷ 2, but because there are two triangles, it isn't necessary)
96 + 448 (the LA) = 544
So the SA = 544 in²
hope this is right:)
Given the function y = x/3 + 1, suppose you have a function value where x (input) is 6. What would be the corresponding y value (output)?
Answer:
3
Step-by-step explanation:
Given the function : y = x/3 + 1
If an input value, x is given as 6 ;
Output value, y can be obtained by Substituting the value x = 6 into the function and calculating the value of y
Calculation goes thus ;
y = 6/3 + 1
y = 2 + 1
y = 3
Output, y = 3

Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is inches. The heights of 10 randomly selected students are 75,62,69,65,66,64,67,70,74 and 63.
Answer:
The population mean = sample mean = x`= 67.5
Population standard deviation = 13.369
Sample standard deviation= 4.225
Step-by-step explanation:
AS the population mean is not given we will calculate it from the sample.
The mean of the sampling distribution is equal to the population mean .
The sample mean is calculated by
x`= ∑x/n= 75,+ 62, +69,+65,+66,+64, +67,+70,+74 + 63/10
x`=675/10= 67.5
The standard deviation of the sample is equal to
u = σ/ √n where σ is the population standard deviation and n is the number of observations.
Calculating the sample mean
s= √∑xi²/n- (∑x/n)²
s= √(45741/10)- (675/10)²
s= 4.2249
σ= u*√n= 4.229 *√10
σ=13.360
