Which of the following could be folded to produce the object above?

Answer:

1288

Step-by-step explanation:

Triangles on the top have surface area 15*14/2 there are four of them so multiply by four to get 420.

The rectangular sections all have area 12*14 except for the base. There are four of these equal sections, so the combined area is 672.

Lastly, the base has area 14*14, which is 196.

Summing all of these we get 1288

Answer:

3x + 2

Step-by-step explanation:

6x + 1 - (3x-1) < distribute the negative sign into the expression

6x + 1 -3x + 1 < combine like terms

6x - 3x = 3x

1 + 1 = 2

our simplified expression is:

3x + 2

Answer: 2.61

Step-by-step explanation:

Given data (x) :  7,5,10,11,12

Mean of the data : [tex]\overline{x}=9[/tex]

Number of data values : n= 5

Now, [tex]\sum (x-\overline{x})^2=(7-9)^2+(5-9)^2+(10-9)^2+(11-9)^2+(12-9)^2[/tex]

i.e. [tex]\sum (x-\overline{x})^2=34[/tex]

Now, the standard deviation for this data is given by :-

[tex]\sigma=\sqrt{\dfrac{\sum  (x-\overline{x})^2}{n}}\\\\\sigma=\sqrt{\dfrac{34}{5}}=2.60768096208\approx2.61[/tex]

the answer is to your question is 48

Answer:

48 square units

Step-by-step explanation:

to find areas of unusual figures, we divide the section into more easy figures to find its area, in this case we can divide the parallelogram into two triangles, drawing a line from point D to point B

then we will have two triangles whose area is easier to find,let´s see the AB-BD-DA triangle

[tex]A=\frac{b*h}{2}[/tex]

b= 6 units (from -6 to zero)

h=8 units ( from -4 to 4)

[tex]A=\frac{6*8}{2} =24[/tex]   square units

the area of the triangle DC-CB-BD is the same,

it's the same triangle but turned up,  so we have a  total area

At=24 square units* 2= 48  square units

Have a great day

Answer:

A. (4, 7)

Step-by-step explanation:

y = 2x - 1

y = x + 3

y = x + 3

2x - 1 = x + 3

2x = x + 4

x = 4

y = 2x - 1

y = 2(4) - 1

y = 8 - 1

y = 7

Final answer:

The scale factor of all radii of circle Y to all radii of circle Z is 0.4.

Explanation:

To find the scale factor of all radii of circle Y to all radii of circle Z, we can compare their radii.

Circle Y:
Center: (2,3)
Radius: 4

Circle Z:
Center: (2,-3)
Radius: 10

The scale factor is determined by comparing the radii of the two circles. The radius of circle Y is 4 and the radius of circle Z is 10. To find the scale factor, we divide the radius of circle Y by the radius of circle Z: 4/10 = 0.4.

Therefore, the scale factor of all radii of circle Y to all radii of circle Z is 0.4.

A. Both triangles equal 50 and 10x5 is 50. Therefore, y=5.

Answer:

The answer is 6x^2-8x+2

Step-by-step explanation:

To find the area, you have to multiply the length by the width.

You will get the equation of (6x-2)(x-1). Then, you multiply and find the answer, 6x^2-8x+2.

Answer:

The measure of angle BCD is [tex]68.5\°[/tex]

Step-by-step explanation:

step 1

Find the value of x

we know that

[tex]m<ABD+m<BCD+m<EDF=180\°[/tex] -----> form a straight line

substitute the values

[tex](3x+4)\°+(6x-8)\°+(7x-20)\°=180\°[/tex]

[tex](16x-24)\°=180\°[/tex]

[tex]16x=180\°+24\°[/tex]

[tex]16x=204\°[/tex]

[tex]x=12.75\°[/tex]

step 2

Find the measure of angle BCD

[tex]m<BCD=(6x-8)[/tex]

substitute the value of x

[tex]m<BCD=6(12.75)-8=68.5\°[/tex]

Answer:

D. Exponential Growth.

Step-by-step explanation:

Suppose the equation is  y = 10^x   which is an exponential function.

When  x = 1 , y = 10, when x = 2, y = 10^2 = 100, when x = 3, y = 10^3 = 1000 which is 10 times more powerful for each unit increase of x.

The answer is Exponential growth.

Answer:

6/5

Step-by-step explanation:

120% turns into 120/100 and from there you simply

To convert 120% to a fraction in its simplest form, write it as 120/100 and then simplify the fraction by dividing both the numerator and the denominator by their greatest common factor, which is 20. This results in 6/5.

To express 120% as a fraction in simplest form, you first write the value of the percent as a fraction with a denominator of 100. This is essentially how you convert percentages into fractions. This means that 120% becomes 120/100.

Next, you need to simplify this fraction. To simplify a fraction, you find the greatest common factor of both the numerator and the denominator and then divide each by that number. In this case, the greatest common factor is 20, so you divide both 120 and 100 by 20.

Doing so, the fraction becomes 6/5. Therefore, 120% can be expressed as the fraction 6/5 in simplest form.

After distributing the multiplication and combining like terms, the expression 1+4(3x-10)-12x simplifies to -39, which proves it is not equivalent to -9.

To determine if the expression 1+4(3x-10)-12x is equivalent to -9, we need to simplify the expression first. Let's do that step by step:

After simplifying the expression, we end up with -39, which is not equivalent to -9. Therefore, the given expression 1+4(3x-10)-12x is not equivalent to -9.

The 23rd term of the sequence [0.1,0.15,0.2,0.25...] is 1.2. This sequence is an arithmetic progression with a common difference of 0.05.

This question is about finding the 23rd term in the sequence [0.1,0.15,0.2,0.25...]. This sequence represents a simple arithmetic progression where the typical difference between two consecutive terms is 0.05.

To find the 23rd term, you can use the formula for the nth term, an arithmetic progression, which is a+n*d where a is the first term, n is the term number, and d is the common difference. Therefore, the 23rd term is a + (n-1)*d equals 0.1 + (23-1)*0.05 = 1.2.

Answer:

D) 29-2n

Step-by-step explanation:

The average of [tex]3a[/tex] and [tex]2b[/tex] satisfies

[tex]\dfrac{3a+4b}2<50[/tex]

Then

[tex]a=2b\implies\dfrac{3(2b)+4b}2=5b<50\implies b<10[/tex]

[tex]a=2b[/tex], so if [tex]a[/tex] must be an integer, then the largest integer value it can take on is 19 if [tex]b[/tex] can be a rational number (in which case [tex]b=9.5[/tex]) or 18 if [tex]b[/tex] must also be an integer.

Given that none of the provided answer choices lists 18 or 19, I'd bet there's a typo and you're supposed to find the maximum integer value of [tex]b[/tex], in which case the answer would be B as the largest integer value would be 9.

Answer:

540 degrees.

Step-by-step explanation:
