Answer:
[tex]x=\frac{7}{30}[/tex]
Step-by-step explanation:
Given the following question:
[tex]x+\frac{2}{3} =\frac{9}{10}[/tex]
In order to find the answer to this question we need to subtract 9/10 from 2/3. To do this we need to find the common denominator, and then subtracting the numerators.
[tex]\frac{9}{10} -\frac{2}{3}[/tex]
[tex]\frac{9}{10} \times3=\frac{27}{30}[/tex]
[tex]\frac{2}{3} \times10=\frac{20}{30}[/tex]
[tex]27-20=7=\frac{7}{30}[/tex]
[tex]x=\frac{7}{30}[/tex]

Dilate the rectangle below by a scale factor of 2. If the current side lengths are 15 and 8, what are the side lengths on the new dilated rectangle?
In your answer, give the new side lengths for the dilated image and explain how you calculated them.
Answer:
AB and CD would be 30
AC and BD would be 16
Step-by-step explanation:
The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.
The side lengths on the new dilated rectangle will be 30cm and 16cm
How to calculate dilationGiven the following parameters
Length = 8cmBreadth = 15cmIf the length and breadth are dilated by a factor of 2, hence the new dimansion will be:
New length = 2(15) =30cm
New width =2(8) = 16cm
Hence the side lengths on the new dilated rectangle will be 30cm and 16cm

The image of the point (2, -1) under a translation is (4,2). Find the coordinates of the image of the point (-2,9) under the same translation.
Answer:
The coordinates of the image of the point (6,6) under the same translation is: (9, 2)
Hence, option C is correct.
Step-by-step explanation:
The image of the point (2, 1) under a translation is (5, -3).
It means when we horizontally move 3 units to the RIGHT i.e. adding 3 units to the x-coordinate and vertically move 4 units DOWN i.e. subtracting 4 units from the y-coordinate of the original point (2, 1), we get the coordinates of the image (5, -3).
Thus,
The rule of translation can be formulated such as:
(x, y) → (x + 3, y - 4)
(2, 1) → (2 + 3, 1 - 4) → (5, -3)
Thus,
Under the same rule of translation, we can determine the coordinates of the image of the point (6,6):
(x, y) → (x + 3, y - 4)
(6, 6) → (6 + 3, 6 - 4) → (9, 2)
Therefore, the coordinates of the image of the point (6,6) under the same translation is: (9, 2)
Hence, option C is correct.

Practice using the work formula. A bathtub that holds 42 gallons of water is filling at a rate of 4 gallons per minute. How long will it take to fill the tub? Enter your answers into the boxes. Enter the time t as a decimal. W = rt =
gal = gal/min. t ga • gal/min = t min = 1
Answer: The percentage of the tub after 6 minutes is 30 %
Step-by-step explanation: The calculation can be done as follows
1 minutes= 4 gallons
6 minutes= 4×6
= 24 minutes
If the bathtub can hold 80 gallons of water then the percentage of the tub after 6 minutes can be calculated as follows
= 24/80
= 0.3 × 100
= 30 %
Hence the percentage of the tub will be filled after 6 minutes is 30 %

One number is 20 more than two times another. Find the two numbers if their sum is 110.
Answer:
30, 80
Step-by-step explanation:
Let the smaller number be [tex]x[/tex]. Then, the other number is [tex]2x+20[/tex]. The sum is 110, so
[tex]x+(2x+20)=110.[/tex]
Simplifying gives
[tex]3x+20=110[/tex].
Subtracting 20 from both sides gives
[tex]3x=90[/tex].
Dividing by 3 gives
[tex]x=30[/tex].
The smaller number is 30 and the larger number is 2(30)+20=80.

Answer:
The side length for A and B is 30 and the side length for B and D is 16, in the new dilated rectangle. The reason we multiplied by 2 is because 2 is greater than 1, and this means the image is an enlargement.
Step-by-step explanation:
Dilation is where the polygon grows or shrinks but keeps the same overall shape. A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image. If the scale factor is between 0 and 1 the image is a reduction. If the scale factor is greater than 1, the image is an enlargement. This means that the image, A’, is twice as large as the pre-image A. This means that the image, A’, is twice as large as the pre-image A.
Since 2 is greater than 1, the image is an enlargement
So we do 2*15 and 2 * 8
And we get
30 and 16
The side length for A and B is 30 and the side length for B and D is 16.

I am confused on this question
============================================
Explanation:
x = number of years
y = number of grills sold
The equation we'll use is the exponential equation [tex]y = 3300(1.06)^x[/tex]
The 3300 of course is the initial amount sold. The 1.06 as the base indicates that the sales increase by 6% each year. Think of it the 1.06 as 1+0.06 = 100% + 6%
If we plugged x = 0 into that equation, then we get
[tex]y = 3300(1.06)^x = 3300(1.06)^0 = 3300[/tex]
which helps confirm the correct equation.
----------------
Now plug in x = 6 to find the sales for year 6.
[tex]y = 3300(1.06)^x = 3300(1.06)^6 \approx 4681.11 \approx 4681[/tex]
The projected sales for year 6 are about 4681 grills. This is an estimate based on the assumption that the sales will increase by 6% each year. Of course, the reality is that things aren't always so simple like this (but it should give a fairly good idea of what's going on).
