Answer:

2. 10/3.

Step-by-step explanation:

The numerator x/2 + x/ 3

= 3x/6 + 2x / 6

= 5x / 6

Now divide this by x/4

5x / 6 / x/4

= 5x/6 * 4/x .    The x's cancel so this

=  20/6

=  10/3.

Answer:

   86 m²

Step-by-step explanation:

It can be convenient to think of the figure as an 8×12 rectangle with a 4×5 triangle cut off the corner.

The rectangle area is the product of its length and width:

  (12 m)×(8 m) = 96 m²

The triangle area is half the product of its base and height:

  (1/2)(4 m)(5 m) = 10 m²

Then the area of the figure is the difference of these:

  96 m² -10 m² = 86 m²

Let’s find the amount of heartbeats for 1 minute, so it’s easier to solve.

Since we divide 4 by 4 to get 1, divide 240 by 4 to get the equivalent.

240/4=60.

Your heart beats 60 times per minute.

Since there are 60 minutes in an hour, multiply the amount of heartbeats per minute (60) by 60.

60*60=3,600

Your heart beats 3,600 times per hour.

Hope this helps!

Answer:

  Perpendicular

Step-by-step explanation:

Linear equations will describe parallel lines when the lines have the same slope. These equations are written in slope-intercept form, so we can easily determine that the slopes are ...

  f(x): slope is 5/6

  g(x): slope is -6/5

These are not the same, so the lines are not parallel.

__

The lines will be perpendicular when the product of their slopes is -1. Here, that product is ...

  (5/6)(-6/5) = -30/30 = -1

These equations describe lines that are perpendicular.

Answer:

8 batches.

Step-by-step explanation:

Beth made 2.5 batches of blueberry muffins = 15 muffins

Beth needs 60 muffins in total. She already has 15 therefore she only needs 45 more.

45/6 = 7.5

7.5 would not be enough. You need to round up to 8.

Answer:

B)mean of data is closest to number 3.

Step-by-step explanation:

Given  : Histogram .

To find : Which of the following numbers is closest to the mean of this distribution.

Solution : We have given that histogram

We have data 1 , 2, 3, 4, 3, 2, 1.

Total number of data = 7

We need to find mean of the data

Mean = [tex]\frac{1+2+3+4+3+2+1}{7}[/tex].

Mean = [tex]\frac{16}{7}[/tex].

Mean = 2.2

Therefore, mean of data is closest to number 3.

The simplified ratio of Alice's measurements to Will's measurements is 26:19 when both measurements are converted to milliliters.

The ratio of Alice's measurements to Will's measurements can be found by converting both measurements to the same units and then simplifying the resulting fraction. Alice's measurement is in liters and Will's measurement is in milliliters. We know that 1 liter equals 1,000 milliliters, so Alice's measurement converted to milliliters is 6.5 liters * 1,000 = 6,500 milliliters.

Therefore, the ratio of Alice's measurement to Will's measurement in milliliters is 6,500:4750. To simplify this ratio, you can find the greatest common divisor (GCD) of the two numbers and divide both numbers by the GCD. In this case, the GCD of 6,500 and 4,750 is 250. Thus, the simplified ratio is 26:19.

#SPJ3

The ratio of Alice's measurements to Will's measurements is approximately [tex]\[ \frac{4750 \text{ milliliters}}{1000} = 4.75 \text{ liters} \][/tex]

To compare Alice's measurement to Will's, we need to express them using the same unit. Let's convert Will's measurement from milliliters to liters:

1 liter = 1000 milliliters

So, Will's measurement of 4750 milliliters is equivalent to:

[tex]\[ \frac{4750 \text{ milliliters}}{1000} = 4.75 \text{ liters} \][/tex]

Now, we can compare Alice's and Will's measurements:

Alice's measurement: 6.5 liters

Will's measurement: 4.75 liters

The ratio of Alice's measurements to Will's measurements is:

[tex]\[ \frac{\text{Alice's measurement}}{\text{Will's measurement}} = \frac{6.5}{4.75} \][/tex]

To simplify the ratio, we can multiply both the numerator and the denominator by 4 to get rid of the decimal in the denominator:

[tex]\[ \frac{6.5 \times 4}{4.75 \times 4} = \frac{26}{19} \][/tex]

So, the ratio of Alice's measurements to Will's measurements is [tex]\( \frac{26}{19} \)[/tex].

The answer is:

The equation that is represented by the shown graph is the equation from the option D.

[tex]y=e^{x}-4[/tex]

Since we are given two types of functions, exponential and logarithmic, we need to remember that there is just an option that matches with the graph.

So, from the graph we can see that we are looking for an exponential function which intercepts are located at the point (0,-3) and a point which y-coordinate is equal to 0 and its x-coordinate is located at the x-axis between the number 1 and 2.

From the given options we can see that the only exponential function that intercepts the function at y equal to -3 is the fourth option, so, let's prove that:

Option D,

[tex]y=e^{x}-4[/tex]

Finding the y-intercept, we need to make "x" equal to 0, so:

[tex]y=e^{x}-4[/tex]

[tex]y=e^{0}-4[/tex]

[tex]y=1-4=-3[/tex]

So, we know that the y-intercept point is located at (0,-3)

Finding the x-intercept, we need to make "y" equal to 0, so:

[tex]0=e^{x}-4[/tex]

[tex]e^{x}=4[/tex]

[tex]ln(e^{x})=ln(4)\\x=ln(4)=1.386[/tex]

So, we know that the x-intercept point is located at (1.386,0)

Hence, we have that the axis interception points are (0,-3) and (1.386,0), so, the function that matches with the shown graph is the function from the option D.

[tex]y=e^{x}-4[/tex]

(the comment answers, since someone already did the other ones)
(these are all plato answers btw..)
Part E

area of rectangle i = 20 cm²
area of rectangles i and iii = 2 × 20 cm²= 40 cm²

Part F

total area of the rectangles = 32 cm² + 20 cm² + 20 cm² = 72 cm²

Part G

To find the surface area of the prism, I need to know the areas of its bases and lateral faces, which are triangles i and ii and rectangles i, ii, and iii.

Part H

surface area of the prism = areas of bases and faces =
areas of two triangles + area of one large rectangle + areas of two smaller rectangles =
6 cm² + 32 cm² + 40 cm² =
78 cm2

Part I

This statement is false. Only two rectangles in the figure have equal areas. The third rectangle is larger than the other two.

Part J

This statement is true. The triangles are the bases of the prism, so they are congruent. Congruent triangles have the same area.

Step-by-step explanation:

Answer:

Lucy bought 4 placemats.

Step-by-step explanation:

Let n be the number of placemats Lucy bought.

1 doormat = $7

1 placemat = $2

n placemats = $2n

Total = $(7+2n)

Total number of objects bought = n+1

Average [tex]=\dfrac{\$(7+2n)}{n+1}[/tex]

So,

[tex]\dfrac{\$(7+2n)}{n+1}=\$3[/tex]

Solve this equation:

[tex]7+2n=3(n+1)\\ \\7+2n=3n+3\\ \\3n-2n=7-3\\ \\n=4[/tex]

Hence, Lucy bought 4 placemats.

Answer:x=13

Step-by-step explanation:

Answer:

x = 13

Step-by-step explanation:

Since the polygons are similar, their side lengths will be proportionate.

So, The ratio (x - 3)/2.5 will be proportionate to 16/4 (4).

That said, we can get that (x - 3)/2.5 = 4

Multiply: x - 3 = 10

Add: x = 13

1. Let S represent the cost of the sofa and C represent the cost of the chair.

If the sofa costs $50 less than three times the cost of the chair, then effectively we can write this as:

S = 3C - 50

If the sofa and chair together cost $650, we can write this as:

S + C = 650

2. Now, we can find out how much the sofa and chair cost by solving the two equations we obtained above for C, and substituting S = 3C - 50 into S + C = 650. Thus, we get:

S + C = 650

if S = 3C - 50, then:

3C - 50 + C = 650

4C - 50 = 650 (Add C and 3C)

4C = 700 (Add 50 to both sides)

C = 175 (Divide both sides by 4)

Thus, the cost of the chair is $175. Now, to find the cost of the sofa we need to simply substitute C = 175 into our first equation, S = 3C - 50:

S = 3(175) - 50

S = 525 - 50

S = 475

Thus, the sofa costs $475.

3. Now that we know that the sofa costs $475 and the chair costs $175, all we need to do is to subtract the cost of the chair from the cost of the sofa to find the difference in price:

475 - 175 = 300

Therefor, the sofa costs $300 more than the chair (answer C).

Answer:

72* 62* & 60* 30* triangles

Step-by-step explanation:

I just remember rhombuses being made with 60 degree triangles from all the examples I did. This may be wrong though. But 90 percent confident lol.

Answer: the triangles marked 75 degrees and 45 degrees

Step-by-step explanation:

A rhombus has equal opposite obtuse angles with equal acute angles.

The answer would be B (the symbol ~ means similar. In other words, that they are the same shape but not the same size).

It can't be A because the symbol ≈ means "approximately"

It can't be C because the symbol = means equal

It can't be D because the symbol ≅ means congruent

[tex](4c + 7)^2=16c^2+56c+49[/tex]

Answer:

Step-by-step explanation:

Our equations are

[tex]y = -3x^2 + x + 12\\y = 2x^2 - 6x + 5\\y = x^2 + 7x - 11\\y = -x^2 - 8x - 16\\[/tex]

Let us understand the term Discriminant of a quadratic equation and its properties

Discriminant is denoted by  D and its formula is

[tex]D=b^2-4ac\\[/tex]

Where

a= the coefficient of the [tex]x^{2}[/tex]

b= the coefficient of [tex]x[/tex]

c = constant term

Properties of D: If D

i) D=0 , One real root

ii) D>0 , Two real roots

iii) D<0 , no real root

Hence in the given quadratic equations , we will find the values of D Discriminant  and evaluate our answer accordingly .

Let us start with

[tex]y = -3x^2 + x + 12\\a=-3 , b =1 , c =12\\D=1^2-4*(-3)*(12)\\D=1+144\\D=145\\D>0 \\[/tex]

Hence we have two real roots for this equation.

[tex]y = 2x^2 - 6x + 5\\[/tex]

[tex]y = 2x^2 - 6x + 5\\a=2,b=-6,c=5\\D=(-6)^2-4*2*5\\D=36-40\\D=-4\\D<0\\[/tex]

Hence we do not have any real root for this quadratic

[tex]y = x^2 + 7x - 11\\a=1,b=7,-11\\D=7^2-4*1*(-11)\\D=49+44\\D=93\\[/tex]

Hence D>0 and thus we have two real roots for this equation.

[tex]y = -x^2 - 8x - 16\\a=-1,b=-8,c=-16\\D=(-8)^2-4*(-1)*(-16)\\D=64-64\\D=0\\[/tex]

Hence we have one real root to this quadratic equation.

Answer:

The reflection image of P(0, 0) after two reflections is (8,-6)

Step-by-step explanation:

step 1

Find the coordinates of point P after reflection across x=4

we know that

The distance from point P to the line x=4 is equal to 4 units

so

(0,0) -----> (4+4,0) ----> (8,0)

The reflection image of P is (8,0)

step 2

Find the coordinates of point (8,0) after reflection across y=-3

The distance from point (8,0) to the line y=-3 is equal to 3 units

so

(8,0) -----> (8,-3-3) ----> (8,-6)

Answer:

the probability of drawing three consecutive red marbles is based on how many red marbles you have and many marble there is in total.

Answer:

27/512

Step-by-step explanation:

P(3 consecutive red)=P(red)×P(red)*P(red)=3/8*3/8*3/8=27/512.

The reason P(red)=3/8 for each picking of marble us because you are putting the marble back in and there are 3 red while you have 8 marbles in all.

Answer: c. 6

You have a rectangle that is 8 ft by 10 ft

Area = 8 * 10 = 80 square feet.

Then there is a triangle 8 ft high with a base of 4 feet.

Area = /2 x 8 x 4 = 16 square feet.

Add together for total area:

80 + 16 = 96 square feet.

A simple method of calculating Area is multiplying the Length times the Width. It is much harder to calculate the entire thing all at once, so it is easier to rather keep the shapes separate.

10 x 8 = 80. This is the area of your first shape, the Rectangle.

You can do the same with the triangle, although triangles are only half a square. You also only multiply the flat sides, not the slanted side, the side with 8.9.

8 x 4 = 32. Because the shape is a triangle wedge, half a square, you divide your answer, 32, by 2, to get half of 32, which is 16.

Then add the two areas, 16 and 80, which is 96.

(The little box in the bottom right corner of the square is just an angle, it represents that it is a right angle, ignore it if you didn't know what it was.)

Answer:

Neither

Step-by-step explanation:

step 1

Verify if the lines are parallel

we know that

If two lines are parallel, then their slopes are the same

In this problem the slope of f(x) =2/7 and the slope of g(x)=7/2

Compare

2/7≠7/2

therefore

The lines are not parallel lines

step 2

Verify if the lines are perpendicular

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

In this problem the slope of f(x) =2/7 and the slope of g(x)=7/2

Multiply

2/7*7/2=1

1≠-1

therefore

The lines are not perpendicular
