Answer:
5 I think
Step-by-step explanation:
Well, 0.1 and 0.5 goes in anything so I doubt that's it, 2 goes in 10 but not 5, actually. I think if it's division than 2. Not 1,000 percent sure tho
Answer:
0.5
Step-by-step explanation:
So we know the orginal is 10 in size.
The new is 5 in size.
We can think of this as 10 : 5
To find the exact scale, we can divide both by the GCF.
The GCF is the greatest common factor between two numbers.
In this case, the GCF would be 5, now lets divide:
10/5 : 5/5
=
2 : 1
So we can see the ratio is 2 to 1.
Now, the scale is not 2.
The new ratio is 2 : 1, but 2 is the orginal. 1 is the scaled value.
To find the scale, you must divide the new scaled value by the orginal value:
1 / 2
=
1/2
So this is your scale factor.
There is actually another way to do this as well, which is quicker.
Take the new value, 5, and divide it by the orginal value, 10:
5/10
=
1/2
Either way, you get 1/2 as your answer.
Hope this helps!

(x + 2)(3x - 4) = 3x^2 - 4x + 6x - 8 = 3x^2 + 2x - 8
If x varies inversely as the square of y and if x=3 when y=-1, what is the value of x when y =3
Answers
Answer:
[tex]x[/tex] would be [tex](1/3)[/tex] when [tex]y = 3[/tex].
Step-by-step explanation:
The question states that [tex]x[/tex] varies "inversely" as [tex]y^2[/tex]. In other words, there is a non-zero number [tex]a[/tex] (a constant) such that:
[tex]\displaystyle x = \frac{a}{y^2}[/tex].
The challenging part is to find the value of [tex]a[/tex] in this equation.
Given that [tex]x = 3[/tex] when [tex]y = -1[/tex], replace the [tex]x[/tex] in this equation with [tex]3[/tex] and [tex]y[/tex] with [tex](-1)[/tex]. This equation should still be valid:
[tex]\displaystyle 3 = \frac{a}{(-1)^{2}}[/tex].
Solve for [tex]a[/tex]:
[tex]a = 3 \times (-1)^2 = 3[/tex].
Hence, the relation between [tex]x[/tex] and [tex]y[/tex] becomes:
[tex]\displaystyle x = \frac{3}{y^2}[/tex].
Find the value of [tex]x[/tex] when [tex]y = 3[/tex] by replacing the [tex]y[/tex] in this equation with [tex]3[/tex].
[tex]\displaystyle x = \frac{3}{3^2} = \frac{1}{3}[/tex].
In other words, the value of [tex]x[/tex] would be [tex]\displaystyle \frac{1}{3}[/tex] when [tex]y = 3[/tex].

The sum of two numbers is –25. One number is 10 more than
the other one. Find the numbers.
Answers
Answer:
A = -7.5 B = -17.5
Step-by-step explanation:
A + B = -25
A = B + 10
Plug the second equation into the first equation:
B + 10 + B = -25
2B = -35
B = -17.5
Plug that value into the first equation:
A - 17.5 = -25
A = -7.5

Answers
Answer: [tex]\text{m}\angle T=45^{\circ}[/tex]
Step-by-step explanation:
Given: In ΔSTU, [tex]\text{m}\angle S = (2x+10)^{\circ}[/tex] , [tex]\text{m}\angle T = (3x-9)^{\circ}[/tex], [tex]\text{m}\angle U = (6x-19)^{\circ}[/tex]
To find: [tex]\text{m}\angle T[/tex].
We know that the sum of all the angles of a triangle is [tex]180^{\circ}[/tex].
In ΔSTU,
[tex]\text{m}\angle S+\text{m}\angle T+\text{m}\angle U=180^{\circ}\\\\ 2x+10+3x-9+6x-19=180\\\\ 11x-18=180\\\\11x =180+18\\\\11x=198\\\\x=\frac{198}{11}\\\\ x=18[/tex]
[tex]\text{m}\angle T = (3(18)-9)^{\circ}\\\\=(54-9)^{\circ}\\\\= 45^{\circ}[/tex]
Hence, [tex]\text{m}\angle T=45^{\circ}[/tex]

3y - 2 = 13 solve for y
Answers
Answer:
y = 5
Step-by-step explanation:
3y - 2 = 13
We are solving for y, so we want to isolate it.
Add 2 to both sides.
3y = 15
Continue isolating y by dividing both sides by 3.
y = 5
Check your answer by plugging it back into the original equation.
3y - 2 = 13
3(5) - 2 = 13
Multiply.
15 - 2 = 13
Subtract.
13 = 13
Your answer is correct.

For $155.50, a cosmetician buys 7 L of moisturizer and repackages it in 250-milliliter jars. Each jar costs the cosmetician $0.50. Each jar of moisturizer is sold for $8.95. Find the profit on the 7 L of moisturizer.
Answers
Answer:
$81.10
Step-by-step explanation:
Profit = total revenue - total cost
1 liter = 1000 mm
7 liter = 7000 mm
Number of jars needed = 7000 / 250 = 28
total revenue = number of jars sold x price per jar
28 x $8.95 = 250.60
Total cost = $155.50 + (0.5 x 28) = 169.50
Profit = 250.60 - 169.50 = 81.10

Blank 1 = p and q

=================================================
Explanation:
There's a lot of visual noise here, meaning there's a lot of lines and angles to potentially distract. I recommend redrawing things but only drawing lines p and q, and the transversal cut line t. Furthermore, I would mark only angle 8 and angle 13. See the diagram below.
The diagram is optional, but hopefully you can see that the angles are same side interior angles, aka consecutive interior angles. That's why we go with the consecutive interior angles converse
If we drop the "converse" portion, then that theorem says parallel lines lead to supplementary consecutive interior angles. The converse just reverses the flow of the logic.

Mean is a measure of center tendency which can be said to be the average value of a set of data. It can be referred to as the commonest value in a data set. It is the sum of all data values in a given set divided by the number of values.
For example, a test score for a class of 5 is given as 5, 6, 2, 4, 7
The mean = sum of all values/number of data values
= (5 + 6 + 2 + 4 + 7)/5
= 24/5
Mean = 4.8

8 × 3 = 24
8 × 3 = 24
10 × 8 = 80
10 × 8 = 80
Now that I found the area for each face I will just add them up so...
30 + 30 + 24 + 24 + 80 + 80 = 268 therefore the area is 268 square meters Hope that helps!
