Answer:

C.7 weeks

Step-by-step explanation:

Subtract 60 on both sides then you get: 30w=210, then divide both sides and you get w=7, so it'll take 7 weeks

Answer:

C. 7 weeks

Step-by-step explanation:

30w + 60 = 270

        - 60    -60

subtract 60 from both sides of the equal sign.

30w = 210

We need to isolate the variable, which is (w), so divide both sides by 30.

w = 7

It will take 7 weeks for Uma to save enough money to buy the video game system. So the answer is (c).

Answer:

214.08 cm²

Step-by-step explanation:

To find the whole area of an irregular polygon, you must first break it into polygons that are findable. For this figure, we can break it up into two figures, a triangles and a rectangle. To find the triangle, we must first find the height of it. To get that, we take the length of the blue line (the height of the entire figure), and subtract the height of the rectangle (9.6 cm) to  get a height of 5.7 cm for the triangle. the area formula for a triangle is 1/2 of the base multiplied by the height. To get the base of the triangle, we add the base of the rectangle to the parts of the triangle that hang past it (6.2 cm in total). 6.2 + 12.8 gives us 19 cm. Now we have (19 x 9.6) divided by 2 to give us 91.2 cm². The area formula for a quadrilateral is just the base (12.8 cm) multiplied by the height (9.6 cm), to give us 122.88 cm². Add the area of the rectangle to the area of the triangle to get our answer, 214 cm².

Answer: 1 only

Step-by-step explanation:

because u got 60

More than one different triangle can be made using the given condition, therefore, the last option is correct.

An equiangular triangle is one with three equal sides and three equal angles, all of which are measured at 60 degrees.

Given that, each angle of the triangle measures 60°.

Therefore, the triangle is an equiangular triangle.

There exist triangles with the same angle measure of 60° each, but with different side lengths.

Hence, more than one different triangle can be made using the given condition, therefore, the last option is correct.

Answer:

Step-by-step explanation:

first, she would need to get at least 384 stickers in total since 32 (the number of students) x 12 = 384

Each box contains 64 stickers, so 384/64=6

She would need 6 boxes, but the question is asking how many MORE boxes, and she already has 4 boxes so she would need to get 2 more boxes

Divide is the basic multiplication method to distribute the whole of a things  into more parts.The total number of stickers Mrs. Kim bought at the store are 256, the number of stickers that each student will get is 8 and the number of boxes of stickers Mrs. Kim need if she wants each of her students to get  12 stickers is 6.

Total number of boxes are 4.

The number of sticker each box contained is 64.

Divide is the basic multiplication method to distribute the whole of a things  into more parts.

A) Total number of stickers Mrs. Kim bought at the store.

Let Mrs. Kim bought the n number of stickers from the store.

It is given that the each box contained 64 stickers and there are total 4 boxes. Thus the total number of stickers are,

[tex]n=4\times64[/tex]

[tex]n=256[/tex]

Thus the total number of stickers Mrs. Kim bought at the store are 256.

B) The number of stickers that each student will get.

Total number of students in her class is 32.

Total number of sticker is 256.

Let each students will get x number of the sticker. Thus,

[tex]x=\dfrac{256}{32}[/tex]

[tex]x=8[/tex]

Thus the number of stickers that each student will get is 8.

C) The number of boxes of stickers Mrs. Kim need if she wants each of her students to get  12 stickers.

Total number of students in her class is 32.

The number of stickers that each student will get is 12.

Let for 32 students the total number of sticker required is a.Thus,

[tex]a=12\times32[/tex]

[tex]a=384[/tex]

She needs total 384 sticker to distribute 12 stickers to each students. As each box contain 64 stickers. Let b umber of boxes of stickers Mrs. Kim need if she wants each of her students to get  12 stickers.

[tex]b=\dfrac{384}{64}[/tex]

[tex]b=6[/tex]

Thus the number of boxes of stickers Mrs. Kim need if she wants each of her students to get  12 stickers is 6.

Hence the total number of stickers Mrs. Kim bought at the store are 256, the number of stickers that each student will get is 8 and the number of boxes of stickers Mrs. Kim need if she wants each of her students to get  12 stickers is 6.

Answer:

[tex]f(x) = 3^x[/tex] --- Function A

[tex]f(x) = x^2 - 5[/tex] --- Function B

[tex]f(x) = 18x -6[/tex] --- Function C

Step-by-step explanation:

Solving (a): Equation of Function A

An exponential equation is represented as:

[tex]y = ab^x[/tex]

From the graph of function A,

[tex]x = 0\ when\ y = 1[/tex]

[tex]x = 1\ when\ y = 3[/tex]

For: [tex]x = 0\ when\ y = 1[/tex]

[tex]y = ab^x[/tex] becomes

[tex]1 = ab^0[/tex]

[tex]1 = a[/tex]

[tex]a =1[/tex]

For: [tex]x = 1\ when\ y = 3[/tex]

[tex]y = ab^x[/tex] becomes

[tex]3 = a*b^1[/tex]

[tex]3 = a*b[/tex]

Substitute 1 for a

[tex]3 = 1*b[/tex]

[tex]3 = b[/tex]

[tex]b = 3[/tex]

[tex]y = ab^x[/tex] becomes

[tex]y = 1*3^x[/tex]

[tex]y = 3^x[/tex]

Replace y with f(x)

[tex]f(x) = 3^x[/tex]

Solving (b): Equation of Function B

A quadratic equation is represented as:

[tex]y = ax^2 + bx + c[/tex]

From the table of function B,

[tex]x = 3\ when\ y =4[/tex]

[tex]x = 5\ when\ y =20[/tex]

[tex]x = 6\ when\ y =31[/tex]

For: [tex]x = 3\ when\ y =4[/tex]

[tex]y = ax^2 + bx + c[/tex] becomes

[tex]4 = a*3^2 + b*3 + c[/tex]

[tex]4 = a*9 + 3b + c[/tex]

[tex]4 = 9a + 3b + c[/tex]

For [tex]x = 5\ when\ y =20[/tex]

[tex]y = ax^2 + bx + c[/tex] becomes

[tex]20 = a*5^2 + b*5 + c[/tex]

[tex]20 = a*25 + b*5 + c[/tex]

[tex]20 = 25a + 5b + c[/tex]

For [tex]x = 6\ when\ y =31[/tex]

[tex]y = ax^2 + bx + c[/tex] becomes

[tex]31 = a*6^2 + b*6 + c[/tex]

[tex]31 = a*36 + b*6 + c[/tex]

[tex]31 = 36a + 6b + c[/tex]

So, we solve for a, b and c in:

[tex]4 = 9a + 3b + c[/tex]

[tex]20 = 25a + 5b + c[/tex]

[tex]31 = 36a + 6b + c[/tex]

Make c the subject in [tex]4 = 9a + 3b + c[/tex]

[tex]c = 4 - 9a - 3b[/tex]

Substitute [tex]c = 4 - 9a - 3b[/tex] in [tex]20 = 25a + 5b + c[/tex] and [tex]31 = 36a + 6b + c[/tex]

[tex]20 = 25a + 5b + c[/tex] becomes

[tex]20 = 25a + 5b + 4-9a-3b[/tex]

Collect Like Terms

[tex]-4+20 = 25a -9a+ 5b -3b[/tex]

[tex]16 = 16a+ 2b[/tex]

Divide through by 2

[tex]8 = 8a + b[/tex]

[tex]c = 4 - 9a - 3b[/tex]

[tex]31 = 36a + 6b + c[/tex] becomes

[tex]31 = 36a + 6b + 4 - 9a - 3b[/tex]

Collect Like Terms

[tex]-4+31 = 36a - 9a+ 6b - 3b[/tex]

[tex]27 = 27a+ 3b[/tex]

Divide through by 3

[tex]9 = 9a + b[/tex]

Solve for a and b in: [tex]8 = 8a + b[/tex] and [tex]9 = 9a + b[/tex]

Subtract both equations:

[tex]8 - 9 = 8a - 9a + b - b[/tex]

[tex]8 - 9 = 8a - 9a[/tex]

[tex]-1 = -a[/tex]

Divide both sides by -1

[tex]1 = a[/tex]

[tex]a = 1[/tex]

Substitute 1 for a in [tex]9 = 9a + b[/tex]

[tex]9 = 9*1 + b[/tex]

[tex]9 = 9 +b[/tex]

Subtract 9 from both sides

[tex]9-9=9-9+b[/tex]

[tex]0=b[/tex]

[tex]b = 0[/tex]

Substitute [tex]b = 0[/tex] and [tex]a = 1[/tex] in [tex]c = 4 - 9a - 3b[/tex]

[tex]c = 4 - 9*1-3*0[/tex]

[tex]c = 4 - 9-0[/tex]

[tex]c = -5[/tex]

So, the equation is:

[tex]y = ax^2 + bx + c[/tex]

[tex]y=1*x^2 +0*x-5[/tex]

[tex]y=x^2 -5[/tex]

Replace y with f(x)

[tex]f(x) = x^2 - 5[/tex]

Solving (c): Equation of Function C

This is calculated using:

[tex]f(x) =a + (x -1)d[/tex]

Where

[tex]a = 12[/tex] -- the first term

d = the difference between successive terms

[tex]d = 30 -12 = 48-30 = 66 -48[/tex]

[tex]d =18[/tex]

So, we have:

[tex]f(x) =a + (x -1)d[/tex]

[tex]f(x) = 12 + (x - 1)*18[/tex]

Open bracket

[tex]f(x) = 12 + 18x - 18[/tex]

Collect Like Terms

[tex]f(x) = 18x - 18+12[/tex]

[tex]f(x) = 18x -6[/tex]

Function, Gerald should enter to the computer is g(x) = -2(x + 3)² - 4

Correct option is C.

Transformations are changes done in the shapes on a coordinate plane by rotation or reflection or translation.

Given,

Parent function f(x) = x²

g(x) = ?

for reflection over x - axis,

g(x) = -f(x)

g(x) = -x²

For vertical stretch of factor a.

g(x) = a f(x)

g(x) = -2x²

For right shift by a

g(x) = f(x + a)

g(x) = -2(x + 3)²

Shift down by b units

g(x) = f(x) - b

g(x) = -2(x + 3)² - 4

Hence, g(x) = -2(x + 3)² - 4 is the function, Gerald should enter.
