Step-by-step explanation: you guys are welcome! And be blessed

To write the equation 3x + 2y = 4 in slope-intercept form, subtract 3x from both sides, then divide each term by 2. The slope-intercept form of the equation is y = (-3/2)x + 2.

To write the equation 3x + 2y = 4 in slope-intercept form, we need to isolate y on one side of the equation.

Step 1: Subtract 3x from both sides to get 2y = -3x + 4.

Step 2: Divide each term by 2 to get y = (-3/2)x + 2.

Therefore, the equation 3x + 2y = 4 in slope-intercept form is y = (-3/2)x + 2.

Answer:

i times the square root of 3

Step-by-step explanation:

Whenever you take a square root of a number, look for anything that you could take out! Like if you have the square root of 40, that’s 4 * 10, so you could take out a 2 from the square root and leave the 10.

In this, we see that it’s the square root of 3 times the square root of -1, which we can simplify to the square root of 3 times “i.” We use i to represent the square root of -1.

Answer:

-1/14

Step-by-step explanation:

To simplify the expression, you should first divide up the parts to make it easier.  Multiply 1/5 by  -5/7 first.  When you multiply the two fractions, the fives cancel out since there is a five in both the numerator and the denominator.  This leaves us with just -1/7.

[tex]\frac{1}{5} *\frac{-5}{7} =\frac{-1}{7}[/tex]

Now, multiply -1/7 by 2/4.  Notice that you can simplify 2/4 to 1/2.  You can't cancel out anything in this expression so simply multiply the two fractions.

[tex]\frac{-1}{7} *\frac{1}{2} =-\frac{1}{14}[/tex]

I moved the negative sign from the numerator out front, but you don't have to do that.

Answer:

1) D

6) C

Step-by-step explanation:

1) V = Bh

V = πr² (h)

V = π (7²)(5)

V = 49π (5)

V = 245π

V ≈ 769.3

2) V = 1/3 Bh

V = 1/3 (12*12)(9)

V = 1/3 (144)(9)

V = 1/3 (1296)

V = 432

3) V = 4/3πr³

V = 4/3 π (4.5³)

V = 4/3 π (91.125)

V = 121.5π

V ≈ 381.51

4) 3 pairs of rectangles

2(16)(5) = 2(80) = 160

2(16)(11) = 2(176) = 352

The amount of three-dimensional space enclosed by a closed surface is known as volume. The code is 240.

The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity called volume.

1. The volume of a cylinder with a radius of 7 ft and a height of 5 ft is,

[tex]\rm \text{Volume of Cylinder} = \pi r^2 h = \pi \times 49 \times 5=769.7\ ft^3[/tex]

2. The Volume of the Pyramid with a side 12m, while the height is 9m is,

[tex]\rm \text{Volume of Pyramid} = \dfrac13 \times (\text{Area of square}) \times height = \dfrac13 \times 12^2 \times 9 = 432\ m^3[/tex]

3. The volume of the sphere with a diameter of 9 yds, can be written as,

[tex]\rm \text{Volume of sphere}=\dfrac{4}{3} \pi r^3=\dfrac43 \times \pi \times (\dfrac{9}{2})^3=381.7\ yd^3[/tex]

4. The surface area of the cuboid with a length of 16 cm, width of 5 cm, and height of 11 cm can be written as,

[tex]\rm \text{Surface area of Cuboid} = 2[(L\times W)+(W\times H)+(L\times H)][/tex]

[tex]\rm \text{Surface area of Cuboid} = 2[(16\times 5)+(5\times 11)+(16\times 11)] = 622\ cm^2[/tex]

5. The surface area of the given figure can be written as,

Surface Area of figure = 2(Area of the triangle) + Area of slant side + Area of rectangle +  Area of base

[tex]\rm \text{Surface Area of figure} = (\dfrac{2 \times 5 \times 18}{2}) + (18.7 \times 7)+(18 \times 7) + (5 \times 7) = 381.9\ in^2[/tex]

6. The surface area of a cone is given as,

Step-by-step explanation:

Use a median calculator

Final answer:

To find the number in the middle of 8.6 and 21.3, you calculate their average by adding them together and dividing by two, resulting in 14.95.

Explanation:

To calculate the number in the middle of 8.6 and 21.3, we need to find the average of these two numbers. To do this, you add the two numbers together and then divide by two.

The calculation is therefore: (8.6 + 21.3) / 2.

Adding 8.6 and 21.3 gives us 29.9, and dividing 29.9 by 2 gives us 14.95. So, 14.95 is the number in the middle of 8.6 and 21.3.

Final answer:

To determine Miguel's total cost including the 8% sales tax, add the pre-tax total of $20.98 to the sales tax amount, which is calculated as $20.98 multiplied by 0.08, totaling $22.66.

Explanation:

To calculate Miguel’s total cost including an 8% sales tax on his purchases, follow these steps:

First, find the total cost before tax by adding the prices of the items. If Miguel bought items totaling $20.98, this is the pre-tax total.

Next, convert the tax percentage to a decimal form. For an 8% sales tax, this is done by dividing by 100, which gives us 0.08.

Then, calculate the amount of sales tax by multiplying the pre-tax total by the decimal tax rate: $20.98 × 0.08 = $1.6784.

Round the sales tax to the nearest cent, which gives us $1.68.

Finally, add the sales tax to the pre-tax total to find the total cost: $20.98 + $1.68 = $22.66.

The total cost for Miguel after adding the 8% sales tax is $22.66.

The diameter of the cone is 4√3 cm, which is approximately 6.93 cm when rounded to two decimal places.

To find the diameter of the cone, we first need to identify the formula for the volume of a cone, which is V = (1/3)πr^2h. Given that the volume (V) of the ice cream cone is 12π cubic cm and the height (h) is 9 cm, we can set up the equation to solve for the radius (r):

12π = (1/3)πr^2(9)

We can simplify this equation by dividing both sides by π and multiplying both sides by 3/9 (which is the reciprocal of 1/3 times 9):

12 = r^2

Therefore, r = √12 cm. To find the diameter, which is twice the radius, we calculate:

Diameter = 2r = 2(√12) cm = 2(√4√3) cm = 4√3 cm

The diameter of the cone is 4√3 cm or approximately 6.93 cm when rounded to two decimal places.

Final answer:

The reciprocal of -0.07, when rounded to one decimal place, is -14.3.

Explanation:

To calculate the reciprocal of any number, you simply divide 1 by that number.

The reciprocal of a number is the multiplicative inverse of that number.

In this case, for the number -0.07:

The reciprocal of -0.07 is calculated as follows:

Divide 1 by -0.07:

1/-0.07

= -100/7

= - 14.2857 which equals approximately -14.2857.

To round the result to one decimal place, we consider the first decimal digit after the point, which is 2. Since 2 is less than 5, we don't round up the preceding digit.

Round this number to one decimal place, giving us -14.3.

Therefore, the reciprocal of -0.07, correct to one decimal place, is -14.3.

Answer:

Allen- 144 cards

Jane- 288 cards

Bob- 36 cards

Step-by-step explanation:

Here's what we know:

a = 4b (Allen has 4 times Bob's cards)

j = 2a (Jane has twice Allen's)

a + j = 432 (Allen and Jane have 432 cards all together)

Start with substituting:

4b + 2a = 432

4b + 2(4b) = 432

Distribute:

4b + 8b = 432

Simplify:

12b = 432

Divide both sides by 12:

b = 36

To find how much Allen has just multiply 36 times 4.

a= 144 cards

To find how much Jane has multiply 144 times 2.

j= 288 cards

Answer:

156

312 and

39

Step-by-step explanation:

Let Allen be A , Jane be J and Bob be B

Allen has 4 times as Bob

So

A = 4B

Jane has twice as Allen

So

J = 2A

Together, Allen and Jane has 468 cards

A + J = 468

Substitute 2A for J in the third equation.

We have

A + J = 468

A + 2A = 468

3A = 468

Divide both sides by 3

3A/3 = 468/3

A = 156

Recall

A = 4B

Therefore

156 = 4B

Divide both sides by 4

156/4 = 4B/4

39 = B

B = 39

Also,

J = 2A

J =2 x 156

J = 312

Allen has 156 cards

Jane has 312 cards and

Bob has 39 cards
