1. 2 * 13 = 26
2. 10 * x = 10x
26 = 10x
Answer:
X=2.6
Step-by-step explanation:
This shows 'cross multiplying'
This is a 'short cut' method of finding the common denominator of two fractions in order to 'work' with them :
2/x = 10/13 <==== common denominator is 13x
so multiply the L side by 13/13 and the right side by x/x to get
26/13x = 10x / 13x Now with common denominator, you can solve.
Equate the numerators :
26 = 10x <====== there is your 'short cut' found by cross multiplying
x = 26/10 = 2.6

Which equation can be used to determine the value of x?
(3x + 18) = 93
All of these
(3x + 18) + 93 = 90
(3x + 18) + 93 = 180
None of these
Answer:
(3x + 18) + 93 = 180
23 + X
Step-by-step explanation:
(3x + 18) + 93 = 180, its supplymentery
180 - 93 = 87
87 - 18 = 69
3x = 69
69/3 = 23
23 = X
Answer:
Step-by-step explanation:
Remark
You have to assume nothing you should have to assume. You have to assume that 93 degrees on 3x + 18 sit on the same straight line. If it just looks that way, you are on shaky ground. You must be told. It's a good thing to keep in mind. Likely you'll get more questions like this. Just be aware you should not have to assume anything to make the problem work.
If the two angles both have one leg on what is marked as a straight line, then the sum of the two angles must = 180
Solution
The first one is not true. 3x + 18 is smaller than 90 degrees because 93 is more than 90 degrees. If A is true then the line is bent a bit.
B is not true. We just found one equation that doesn't work.
C is not true either. The result of trying to solve C will make x minus because 93>90 and 18 when subtracted makes 3x even more minus.
D is true
(3x + 18) + 93 = 180 Subtract 93 from both sides.
(3x + 18) + 93-93 = 180 - 93 Combine
(3x + 18) = 87 Remove the brackets
3x + 18 = 87 Subtract 18
3x+18-18 = 87-18
3x = 69 Divide by 3
3x/3 = 69/3
Answerx = 23
E is not true because D is true.

What is the ratio for the volumes of two similar spheres, given that the ratio of their radii is 5:6?
Answer:
125 : 216
Step-by-step explanation:
Let the volumes of the spheres be V₁ and V₂ respectively.
Volume (Sphere radius = 5) :
V₁ = 4/3π(5)³V₁ = 4/3π x 125V₁ = 500/3πVolume (Sphere radius = 6) :
V₂ = 4/3π(6)³V₂ = 4/3π x 216V₂ = 864/3πTaking the ratio of V₁ and V₂ :
V₁/V₂500/3π x 3π/864500/864125 : 216Given ratio: [tex](\text{Radius of Sphere}_1 : \text{Radius of Sphere}_2) = (5 :6)[/tex]
Step-1) Multiply both sides of the ratio by x:
[tex]\implies (\text{Radius of Sphere}_1 : \text{Radius of Sphere}_2) = (5x :6x)[/tex]
[tex]\implies \text{Radius of Sphere}_1 = 5x;\ \text{Radius of Sphere}_2 = 6x[/tex]
Step-2) Substitute the radiuses of each sphere into the "Volume formula"
Volume of sphere₁ Volume of sphere₂
[tex]\implies \ \ \ \ \ \ \ \ \dfrac{4}{3} \pi r^{3} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \dfrac{4}{3} \pi r^{3}[/tex]
[tex]\implies \ \ \ \ \ \ \ \ \dfrac{4}{3} \pi (5x)^{3} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \dfrac{4}{3} \pi (6x)^{3}[/tex]
[tex]\implies \ \ \ \ \ \ \ \ \dfrac{4}{3} \pi (5x)(5x)(5x) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \dfrac{4}{3} \pi (6x)(6x)(6x)[/tex]
[tex]\implies \ \ \ \ \ \ \ \ \dfrac{4}{3} \pi (125x^{3} ) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 4 \pi (2x)(6x)(6x)[/tex]
[tex]\implies \ \ \ \ \ \ \ \ \dfrac{500x^{3} }{3} \pi \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 288x^{3} \pi[/tex]
Step-3) Plug the volume of both spheres in ratio form:
The ratio for the volumes of the two spheres must be in the respective place of the ratio for the radiuses of the two similar spheres. Therefore,
Ratio form: [tex]\underline{(\small\text{Volume of sphere}_1 : \text{Volume of sphere}_2)}[/tex]
[tex]\implies \dfrac{500x^{3} }{3} \pi: 288x^{3} \pi[/tex]
Step-4) Simplify both sides of the ratio:
[tex]\implies \dfrac{500x^{3} }{3}: 288x^{3}[/tex]
[tex]\implies \dfrac{500 }{3}: 288[/tex]
[tex]\implies \dfrac{500 }{3}} \div{\dfrac{288}{1} } \implies \dfrac{500}{3} \times \dfrac{1}{288} \implies \dfrac{500}{864} \implies \boxed{\dfrac{125}{216}}[/tex]
Therefore, the ratio for the volumes of two similar spheres is 125 : 216.

Answer:
x is greater than or equal to 16.
Step-by-step explanation:
Hi! It says atleast 80 points, so your sign should be flipped over to show that x+64 needs to be ATLEAST 80. Then they asked you to solve for x. To solve for x, you subtract 64 from each side to get x is greater than or equal to 80-64, otherwise known as 16.
The inequality is [tex]x +64 \ge 80[/tex]
It solves to [tex]x \ge 16[/tex]
She needs at least 16 more points.
=========================================================
Further Explanation:
"At least 80" means "80 or more"
In other words, the lowest grade she can get is 80
x = number of points she needs
x+64 = number of points she has, after adding on the earlier 64 points
The x+64 must be 80 or larger. So the inequality to set up is [tex]x+64 \ge 80[/tex]
You had the right idea, but need to flip the inequality sign.
To solve this inequality, you subtract 64 from both sides and you should end up with [tex]x \ge 16[/tex]
This says she needs at least more 16 points to go with the 64 points she already has.
What is the general form of the equation of the line shown?
Y-2=0
y+2=0
X-2 = 0
Answer:Option A is correct.
y-2=0
Step-by-step explanation:
Option A is correct.
General form of the equation of the line: y-2 = 0
Step-by-step explanation:
The general form of the equation is given by:
y = mx +b where m is the slope and b is the y-intercept.
y-intercepts of the line is the value of y at the point where the line crosses the y-axis(i.e x= 0)
From the given figure;
we can see that the line crosses the y-axis at y =2 and also here the slope is , m= 0
therefore, by definition of y-intercepts
y-intercept (b) = 2
Therefore, the equation of line as shoen in figure is:
y = (0)x + 2
or
y = 2
y-2 = 0
Therefore, the general form of the equation line as shown in the figure is:
y-2 =0

Diego was trying to write (5^2)^4 with a single exponent and wrote (5^2)^4=5^2+^4=5^6. What should the answer be? Explain Diego's error in complete sentences and thoughts.
Answer:
5^8
Step-by-step explanation:
Diego added the exponents. This was an error. If he was simplifying
5^2 × 5^4, then he could add the exponents and get a correct answer. But his problem had a power raised to a power. In this case, you multiply the exponents to simplify.
(5^2)^4 means
5^2×5^2×5^2×5^2
which is
5×5×5×5×5×5×5×5
which is 5^8.

I'm working on a project and im not quite sure what bullet points 1 & 2 are asking. Help would be appreciated by telling me what I have to do.
Answer:
Its like how much you multiply the original shape by, to the new one.
For example, if your new shape is double the size of the original shape, then the scale factor is 2, because you would multiply the original by 2, to get the size of the new.
However, if your new shape is half the size, then the scale factor is 1/2, as you multiply the original by half to get the new shape.
Hope this cleared things up, lmk down below if you any further questions.

What is a cube?It is defined as three-dimensional geometry that has six square faces and eight vertices.
We have a cube shown in the picture.
Area of the cube = 16 square units
Area of cube = side²
Side = √16 = 4 units
Each side of the cube = 4 units.
From the attached figure, we can see each side lies on each quadrant.
Using the distance formula, we can calculate the distance between two
points:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The area of the cube = 4×4 = 16 square units

Find the area of the parking space shown to the right

Answer:
166 1/2 or 166.5
Step-by-step explanation:
The formula for finding area is length*width. This can also just be written as A=l*w. Our area is still unknown, so it'll stay as A in this equation. Here, our length and width don't matter all that much, so we can input them where we please.
Now, we have the equation A=18*9 1/4
So, let's solve! 18*9 1/4 is equal to 166 1/2 or 166.5
With this, the area is equal to 166 1/2 or 166.5
