Answer:
x = 9
Step-by-step explanation:
8 : 3 = 24 : x
=> 8/3 = 24/x
=> x = 24 x 3 / 8
=> x = 3 x 3
=> x = 9

There are t boys in class. There are 7 fewer girls in class. How many students are in class in terms of t?
Answer:
[tex]2t-7[/tex]
Step-by-step explanation:
Let "t" represent the boys in the class then the amount of girls will be:
[tex]t-7[/tex]
Total Students = Number of Boys + Number of Girls
Total Students = [tex]t+t-7[/tex]
Total Students = [tex]2t-7[/tex]
Let's use a few example numbers to see if this equation is true...
[tex]t=10[/tex]
[tex]t-7=10-7=3[/tex]
[tex]10+3=13[/tex]
This means that [tex]2t-7[/tex] must also be equivalent to 13...
[tex]2(10)-7=20-7=13\rightarrow $ Correct![/tex]
Another example...
[tex]t=15[/tex]
[tex]t-7=15-7=8[/tex]
[tex]15+8=23[/tex]
This means that [tex]2t-7[/tex] must also be equivalent to 23...
[tex]2(15)-7=30-7=23\rightarrow$ Correct![/tex]
Both examples have been proven to be true therefore there are...
[tex]2t-7[/tex] students in the class

the ratio of shaded is 8:12 simplified to 3:4
the ration of shaded but with a cross is 7: 12. simplified it least value.
the ration of shaded with a cross and just shaded is 8:12 to 7:12, subtract those and you get 1:12
sooo you're answer is 8:12 - 1:12 to see the shaded with cross

determine if the triangles are similar by side-side-side similarity
Answer:
Side-Angle-Side Similarity Theorem: If an angle of one triangle is congruent to an angle of a second triangle, and the sides that include the two angles are proportional, then the triangles are similar. Side-Side-Side Similarity Theorem: If the corresponding sides of two triangles are proportional, then the triangles are similar.

The production cost, represented by y, of a Bluetooth device, is equal to the product of labour cost (m) and number of devices (x) in addition to a constant equipment renting fee (q) 1.1 write an equation to represent the production cost in terms of m, x and q. 1.2 Change the subject of the formula in 1.1 to: 1.2.1 m; 1.2.2 q, 1.2.3 x. Determine the cost if labour amounts to R1,245, with an equipment renting fee of R250, to produce 5 devices. 1.4 Suppose the production cost is R 18,925, labour cost is and equipment renting fee is R250, determine the number of devices produced. 1.5 Hence, write down the equation with y as the subject (in terms of x). The value of m and q must e indicated. Discuss whether it is possible that any devices are produced if the production cost is R0,00. 1.7 It is required that the production cost must be less than R123 505. Determine the possible number of devices that will be produced. Show your solution graphically. Use interval notation and indicate the restriction on the number type of your answer. Interpret your answer
It should be noted that the equation to represent the production cost will be y = mx + q.
How to calculate the equationFrom the information given, the production cost, represented by y, of a Bluetooth device, is equal to the product of labour cost (m) and number of devices (x) in addition to a constant equipment renting fee (q). This will be: y = mx + q.
Changing the subject of the formula to m will be:

Imagine the center of the Ferris wheel is located at (0, 0) on a coordinate grid, and the radius lies on the x-axis. Write an equation of a circle for your Ferris wheel, and sketch an image of what your Ferris wheel would look like on the grid. Now graph a circle that is similar to the Ferris Wheel. Discuss the transformations needed to show that both circles on your graph are similar.
The transformation needed to show that both circles on the graph are similar is dilation
How to model the equation of the Ferris wheelThe equation of a circle that has its center to be (0,0) is:
[tex]x^2 + y^2 = r^2[/tex]
Where r represents the radius of the circle.
The radius can take any positive value.
Assume r = 5, then the equation becomes
[tex]x^2 + y^2 = 5^2[/tex]
[tex]x^2 + y^2 = 25[/tex]
The above can represent the equation of the Ferris wheel
A circle similar to the Ferris wheel can have the following equation
[tex]x^2 + y^2 = 7^2[/tex]
[tex]x^2 + y^2 = 49[/tex]
The above circle equation has a radius of 7, and it passes through the center
So, we have:
[tex]r = 5[/tex] -- radius of the Ferris wheel
[tex]R = 7[/tex] -- radius of the similar circle
Since both circles pass through the center, either of the circles can be dilated to the other

Answer:
9.6
Step-by-step explanation:
As YZ is parallel to VX, then ΔWYZ ≅ ΔWVX
⇒ WX : WV = WZ : ZX
⇒ 5.6 : (5.6 + 8.4) : 6.4 : (6.4 + J)
[tex]\implies \dfrac{5.6}{5.6+8.4}=\dfrac{6.4}{6.4+J}x^{2}[/tex]
[tex]\implies 5.6(6.4 + J)=6.4 (5.6+8.4)[/tex]

Write an equation that states (x, y) is the same distance from (4, 1) as it is from the x-axis.
The equation that gives all the points (x, y) that are at the same distance from (4, 1) as from the x-axis is:
y = (1/2)*(x - 4)^2 + 1/2.
How we can find the point (x, y)?
First, remember that for a point (x, y), the distance to the x-axis is equal to y.
And we also know that the distance between two points (x₁, y₁) and (x₂, y₂) is:
[tex]d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]
The distance between (x, y) and (4, 1) is:
[tex]d = \sqrt{(x - 4)^2 + (y - 1)^2}[/tex]
And this must be equal to y, so we can write:
[tex]y = \sqrt{(x - 4)^2 + (y - 1)^2}[/tex]
This is the equation we need to solve.
We will get:
[tex]y^2 = (x - 4)^2 + (y - 1)^2\\\\y^2 = (x - 4)^2 + y^2 - 2y + 1\\\\0 = (x - 4)^2 - 2y + 1\\\\2y = (x - 4)^2 + 1\\\\y = (1/2)*(x - 4)^2 + 1/2[/tex]
This equation gives all the points (x, y) that are at the same distance of (4, 1) as from the x-axis.

A garden store bought a fountain at a cost of $995.66 and marked it up 100%. Later on, the store marked it down 25%. What was the discount price?
Answer:
248.91500
Step-by-step explanation:
Answer: $1493.49
Step-by-step explanation:
Mark-up formulas:
price=cost+mark-up
mark-up=mark-up percentage×cost
Discount formulas:
discount price=original price–discount
discount=discount percentage×original price
solve
First find the original price. Write 100% as the decimal 1.00 before using it in the equation.
price
= cost+mark-up
= 995.66+1.00×995.66
= 995.66+995.66
= 1,991.32
The original price was $1,991.32.
Now find the discount price. Write 25% as the decimal 0.25 before using it in the equation.
discount price
= original price–discount
= 1,991.32–0.25×1,991.32
= 1,991.32–497.83
= 1,493.49
The discount price was $1,493.49.
Two card are pulled from a normal deck of 52 cards, without replacement.
What are the odds of the two cards being a pair?
Answer:
The probability that both cards that are drawn are hearts is 1/17.
Step-by-Step-Explanation:
First off, know that there are 13 heart cards in the deck of 52 cards. Therefore, the chance of pulling a single heart card is 13/52. Let's say we do pull a heart card. Since there is no replacement for the heart card taken out of the deck, we now have 12 heart cards out of a deck of 51 cards. The chance of pulling out a heart card in now 12/51. To find the probability that both cards drawn out are hearts, multiply the two fractions together: (13/52)⋅(12/51)=156/2652=1/17.
So hence, your answer is 1/17-----------------------------------——————---------------------------------------------------------
