what is the scale factor of the small triangle to the large triangle?

Answers

Answer:

I'm pretty sure it's 4.3?

Step-by-step explanation:

Because you divide the larger triangles side first because you are figuring out the scale factor of the small triangle to the larger triangle, not the other way around.

Sorry if i'm wrong

Answer:

first, find the area of the small triangle: 3 times 3 equals 9 divided by 2 equals 4.5.

second, find the area of the big triangle: 13 times 13 equals 169 divided by 2 equals 84.5.

Find difference: 84.5 minus 4.5 equals 80

If 2(6 + 3x) + 1 = - 5 + 3(x - 1), what is the value of x?

Answers

Answer: x = -7

Step-by-step explanation:

2(6 + 3x) + 1 = - 5 + 3(x - 1)

(2) (6) + (2) (3x) + 1 = -5 + (3) (x) + (3) (-1)

12 + 6x + 1 = - 5 + 3x + - 1

( 6x ) + ( 12 - 1 ) = ( 3x ) + ( -5 + -3 )

6x + 13 = 3x - 8

6x + 13 - 3x = 3x - 8 - 3x

3x + 13 = -8

3x + 13 - 13 = -8 - 13

3x = -21

3x/3 -21/3

X = -7

12+6x+1= -5+3x-3
3x= -21
x= -7

thirty percent of all seventh graders own a bracelet. explain whether the sample closely estimates the percentage of seventh graders who own a bracelet.

30 seventh graders, 3 own a bracelet

Answers

it doesn’t. if there were 30 7th graders and 30% owned a bracelet that would mean 9 own a bracelet.

The sample of 3 seventh graders who own a bracelet out of 30 seventh graders does not closely estimate the thirty percent of all seventh graders owning bracelets.

What is a percentage?

Percentages are fractions where the denominator is 100.

We have,

Number of seven grade students = 30

Number of students who own a bracelet = 3

The percentage of seven grade student who owns a bracelet:

= (3 / 30) x 100

= (1/10) x 100

= 10 %

This means that 10% of seven grade student owns a bracelet.

Thus, the sample does not closely estimate the percentage of seventh graders who owns bracelets.

Answers

so the equation is 5-x3
x^3=x*x*x
so you have x=-2
That means y=5-(-2*-2*-2)
y=5-(-8) which gives y=13
Do this for every x and get the y

Answer:

y's go

13, 6, 5, 4, -3

Step-by-step explanation:

well so you have the equation y = 5 - x^3

you are given the x for all of them

y = 5 - (-2)^3

5 - (-8) = 13

y = 5 - 0^3

5 - 0 = 5

y = 5 - 1^3

5 - 1 = 4

y = 5 - 2^3

5 - 8 = -3

Let F be the set of fractions in simplest form between 0 and 1 that can be written with a single-digit denominator. Find F and |F|​

Answers

Answer:

|F| is 27, the whole F is "listed" below.

Step-by-step explanation:

The set of possible denominators is the numbers from 2 to 9. Each of them produces a single fraction for each numerator that's coprime to it.

Let's list those for each:

2: 1

3: 1 2

4: 1 3 (2 is not coprime)

5: 1 2 3 4

6: 1 5 (2 3 and 4 are not coprime)

7: 1 2 3 4 5 6

8: 1 3 5 7

9: 1 2 4 5 7 8 (3 and 6 are not coprime)

To make any number from F, just take the denominator from the rows and the numerator from the list. The size of F is 1 + 2 + 2 + 4 + 2 + 6 + 4 + 6 = 27

The set/number of fractions F for each denominator are ; ( 1, 2, 2, 4, 2, 6, 4, 6 ) .while the value | F | = 27

Given that the set of fractions are between 0 and 10. the possible single digit denominators will be ( 2 through 9 ). also the single digit denominators will have to produce a single fraction where its numerator is coprime to the denominator.

note : coprime numbers are a set of numbers whose HCF (highest common factor ) equals 1

denominators                co-prime numerators

    2                                             1

     3                                           1,  2

     4                                           1,  3  

     5                                           1, 2, 3, 4

     6                                           1, 5  

     7                                           1, 2, 3, 4, 5, 6

     8                                           1, 3, 5, 7

     9                                           1, 2, 4, 5, 7, 8

next : Determine the size of F i.e. | F |

The size of F = ∑ number of coprime numerators for each denominator

                     =  1 + 2 + 2 + 4 + 2 + 6 + 4 + 6 = 27

set of fractions F for each single digit denominator  = ( 1, 2, 2, 4, 2, 6, 4, 6 )

How can the product of 5 and 0.3 be determined using this number line? Number line from 0 to 2.0 with tick marks at every tenth. An arrow goes from 0 to 0.3. Enter your answers in the boxes. Make_____ jumps that are each_____unit long. You end at______ , which is the product of 5 and 0.3.

Answers

Answer:

5      0.3     1.5

Step-by-step explanation:

you count by 3

To determine the product of 5 and 0.3 using the number line described, make 5 jumps that are each 0.3 units long, you end up at 1.5.

Since the distance between each consecutive tick marks is 0.3 ; we only need to jump 5 times starting from the 0 towards the right.

Hence, jumping five times towards the right by a distance of 0.3 each time gives a value of 1.5 on the final or end point which is also the product of 0.3 × 5

Answers

9514 1404 393

Answer:

  Wyatt is incorrect in his calculations

Step-by-step explanation:

The units of base area are square inches. When Wyatt multiplies that by height, he gets a number with units of cubic inches. This is a volume, not an area. If Wyatt is trying to compute an area, he is doing it incorrectly.

_____

Additional comment

I find units analysis to be very helpful in keeping calculations of speed, distance, area, volume, acceleration, velocity, and other physical phenomena straight. If the units come out right, chances are much better that the numbers are being combined appropriately.

Wyatt may need to be using the perimeter of the base, rather than the area of the base. Without the diagram it is tough to tell what the calculation should be.

Find the following
(u•w)(2)=
(w•u)(2)=

Answers

Answer:

[tex](u \circ w)(2) = -34[/tex]

[tex](w \circ u) = -49[/tex]

Step-by-step explanation:

We are given these following functions:

[tex]u(x) = 4x + 2[/tex]

[tex]w(x) = -5x + 1[/tex]

The first step to solve this question is finding the composite functions. So

[tex](u \circ w)(x) = u(w(x)) = u(-5x+1) = 4(-5x + 1) + 2 = -20x + 6[/tex]

[tex](w \circ u)(x) = w(u(x)) = w(4x + 2) = -5(4x+2) + 1 = -20x - 9[/tex]

At x = 2

Now we replace x by 2 in each of the functions. So

[tex](u \circ w)(2) = -20(2) + 6 = -40 + 6 = -34[/tex]

[tex](w \circ u)(2) = -20(2) - 9 = -40 - 9 = -49[/tex]
