7a/10 = 77/60

Answer: 0.29

Step-by-step explanation: The first thing that you need to know is that a ton equals 2,000 pounds. Therefore, 6,000 pounds of rocks cost $1,740. In order to solve the problem you need to divide $1,740 by 6,000. 1,740 / 6,000 = .29

Each pound cost $ 0.29. (29 cents)

Answer:  $0.29 per pound

Step-by-step explanation:

[tex]\dfrac{price}{pound}:\ \dfrac{\$1,740}{3\ tons}\times \dfrac{1\ ton}{2,000\ pounds}=\dfrac{\$1,740}{6,000\ pounds}=\large \boxed{\dfrac{\$0.29}{1\ pound}}[/tex]

Answer:

[tex]\large\boxed{y=\dfrac{7}{2}x-18}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:

[tex]3x+4x=2y-9[/tex]

[tex]7x=2y-9[/tex]             add 9 to both sides

[tex]7x+9=2y[/tex]       divide both sides by 2

[tex]\dfrac{7}{2}x+\dfrac{9}{2}=y\to y=\dfrac{7}{2}x+\dfrac{9}{2}[/tex]

Parallel lines have the same slope. Therefore we have the equation:

[tex]y=\dfrac{7}{2}x+b[/tex]

Put the coordinates of the point (4, -4) to the equation:

[tex]-4=\dfrac{7}{2}(4)+b[/tex]

[tex]-4=7(2)+b[/tex]

[tex]-4=14+b[/tex]       subtract 14 from both sides

[tex]-18=b\to b=-18[/tex]

Finally we have the equation:

[tex]y=\dfrac{7}{2}x-18[/tex]

The dimensions of the box are = 4 feet (length); 3 feet(width); 2 feet(height)

So, volume of the box is = [tex]4\times3\times2=24[/tex] cubic feet

The dimensions of the storage locker are = 12 feet(length); 6 feet(width) ; 9 feet(height)

So, volume of the storage locker is = [tex]12\times6\times9=648[/tex]

So, the greatest number of boxes that can be stored are =

[tex]\frac{648}{24}= 27[/tex] boxes

Hence, a maximum of 27 boxes are stored.

Jayden's storage locker has a volume of 648 cubic feet, and each of his boxes has a volume of 24 cubic feet. By dividing the locker's volume by the volume of a single box, we find that Jayden can store a maximum of 27 boxes in the locker.

To determine the greatest number of boxes Jayden can store in the storage locker, we need to calculate the volume of the storage locker and the volume of one box. The storage locker is 12 feet long, 6 feet wide, and 9 feet high, so its volume is calculated as follows:

Storage Locker Volume = length × width × height = 12 ft × 6 ft × 9 ft = 648 cubic feet.

The box has dimensions of 4 feet long, 3 feet wide, and 2 feet high. Thus, its volume is:

Box Volume = length × width × height = 4 ft × 3 ft × 2 ft = 24 cubic feet.

Now, to find the greatest number of boxes that can fit into the locker, we divide the volume of the storage locker by the volume of one box:

Number of Boxes = Storage Locker Volume / Box Volume = 648 cubic feet / 24 cubic feet.

When we perform the division, we get:

Number of Boxes = 27.

Hence, Jayden can store a maximum of 27 boxes in the storage locker when placed upright with a 4-foot by 3-foot side on top.

Answer:

27m

Step-by-step explanation:

The diagram is shown in the attachment.

The height of the hot air balloon is calculated using the tangent ratio.

The tangent ratio involves the side length that is opposite(h) to the given angle (28) and the side length adjacent to the angle.

[tex]\tan 28\degree=\frac{h}{50}[/tex]

This implies that;

[tex]h=\50tan 28\degree[/tex]

[tex]h=26.585m[/tex]

The height is 27m to the nearest meters.

Using the tangent of the angle of elevation, the height of the hot air balloon is calculated to be approximately 26.585 meters.

To find the height of the hot air balloon, we can use trigonometric principles, specifically the tangent function, which relates the angle of elevation to the opposite side (the height of the balloon in this case) and the adjacent side (the distance from you to the balloon).

The angle of elevation to the top of the balloon is given as 28 degrees and the distance from the observer to the balloon is 50 meters. Using the formula for tangent:

tan(angle) = opposite/adjacent

In this case:

tan(28 degrees) = height/50 meters

Therefore, to find the height:

height = 50 meters * tan(28 degrees)

Calculating this using a calculator:

height ≈ 50 * 0.5317

height ≈ 26.585 meters

So, the height of the balloon is approximately 26.585 meters.

Step-by-step explanation:

18 times 7

The maximum number of pages the printer can print in 7 minutes is 119 pages, assuming it prints at the upper limit of 17 pages per minute.

To find the maximum number of pages the printer can print in 7 minutes, we multiply the maximum number of pages it can print per minute by the number of minutes.

Given:

- The printer prints fewer than 18 pages per minute.

- Number of minutes: 7

Let's use the upper limit of the printer's speed, which is 17 pages per minute (since it prints fewer than 18 pages per minute).

Maximum number of pages printed in 7 minutes:

[tex]\[ \text{Pages} = \text{Pages per minute} \times \text{Minutes} \][/tex]

[tex]\[ \text{Pages} = 17 \times 7 \][/tex]

[tex]\[ \text{Pages} = 119 \][/tex]

So, the maximum number of pages the printer can print in 7 minutes is 119 pages.

Step-by-step explanation:

Note there is a difference of 1 between consecutive integers.

let an integer be n then then the next one is n + 1 followed by n + 2

Hence

n + (n + 1) + (n + 2) = 36 → C

Answer: Third option (In step 3 she needed to subtract c rather than divide)

Step-by-step explanation:

When she subtract b from both sides of the equation, she obtained:

[tex]3s-b=a+c[/tex]

Therefore, to leave the a alone at one member of the equation, she needs to subtract c from both sides of the equation.

Then, she would obtain the following:

[tex]3s-b-c=a+c-c\\3s-b-c=a\\a=3s-b-c[/tex]

Therefore the answer is the third option: In step 3 she needed to subtract c rather than divide.

Answer:

The true statement is: In step 3 she needed to subtract c rather than divide.

Step-by-step explanation:

Lets solve our equation [tex]s=\frac{a+b+c}{3}[/tex] step by step.

Step 1. Since 3 is the denominator of the right hand side, we need to multiply both sides of the equation by 3:

[tex]3s=\frac{3(a+b+c)}{3}[/tex]

Now we can cancel the 3 in the numerator and the 3 in the denominator to get

[tex]3s=a+b+c[/tex]

As you can see, the first statement is false

Step 2. Since we want to isolate the variable [tex]a[/tex], we need to subtract b from both sides of the equation:

[tex]3s=a+b+c[/tex]

[tex]3s-b=a+b+c-b[/tex]

[tex]3s-b=a+c[/tex]

The second statement is also false

Step 3. The last thing we to do to isolate [tex]a[/tex] (and solve for it) is subtract c from both sides of the equation:

[tex]3s-b-c=a+c-c[/tex]

[tex]3s-b-c=a[/tex]

[tex]a=3s-b-c[/tex]

Therefore, the third statement is true: In step 3 she needed to subtract c rather than divide.

Step-by-step explanation:

we know that

The volume of the sphere is equal to

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

we have

[tex]r=120/2=60\ mm[/tex] ----> the radius is half the diameter

[tex]\pi=3.14[/tex]

substitute the values

[tex]V=\frac{4}{3}(3.14)(60)^{3}=904,320\ mm^{3}[/tex]

Final answer:

The volume of a sphere-shaped beanbag with a diameter of 120 millimeters is calculated using the formula V = (4/3)πr³, resulting in a volume of approximately 904.32 cubic centimeters.

Explanation:

To calculate the volume of a beanbag in the shape of a sphere, we use the formula for the volume of a sphere, which is V = (4/3)πr³. Given that the diameter of the beanbag is 120 millimeters, we first need to find the radius, which is half of the diameter, so r = 60 millimeters or 6 centimeters. Plugging the values into the formula, we get:

V = (4/3) × 3.14 × (6 cm)³

V = (4/3) × 3.14 × 216 cm³

V = (4/3) × 3.14 × 216

V = (4) × 3.14 × 72

V = 904.32 cm³

Therefore, the volume of the beanbag is approximately 904.32 cubic centimeters (cm³).

Answer:

x=3

z=65

Step-by-step explanation:

6x+97 and 14x+73  are vertical angles which means they are equal

6x+97= 14x+73

Subtract 6x from each side

6x-6x+97= 14x-6x+73

97 = 8x +73

Subtract 73 from each side

97-73 = 8x+73-73

24 = 8x

Divide each side by 8

24/8 = 8x/8

3 = x

Now we need to find z

6x+97  and z are supplementary angles which means they add to 180

6x+97 +z = 180

6(3) +97 +z = 180

18+97+z=180

Combine like terms

115+z = 180

Subtract 115 from each side

115-115 +z=180-115

z = 65

The correct answer is 5

Step-by-step explanation:

To find this, start by multiplying them in any order. For ease, we'll multiply the first and last.

-2/3 * -3 = 2

Now we take that and multiply it by the remaining term.

2 * 2 1/2 = 5

Final answer:

Multiplying −2/3 by 2 1/2 and then by −3 results in the answer 5 after converting the mixed number to an improper fraction, considering the signs during multiplication, and simplifying the result.

Explanation:

To multiply the given numbers and write the answer in simplest form, let's break down the math step by step.

Firstly, convert the mixed number 2 1/2 into an improper fraction. To do this, multiply the whole number by the denominator of the fraction and add the numerator. This gives us 2 x 2 + 1 = 5, so 2 1/2 becomes 5/2.

Now, let's look at the multiplication operation:

−2/3 × (5/2) × (−3) = ( −2 × 5 × −3 ) / ( 3 × 2 )

When multiplying, we multiply the numerators together and the denominators together, which results in:

(−2 × 5 × −3) / (3 × 2) = (+2 × 5 × 3) / 6  = 30 / 6

When considering the signs, remember that when two numbers with the same sign multiply, the result is positive (e.g., −2 × −3 = +6), and when two numbers with opposite signs multiply, the answer is negative (e.g., −3 × 2 = −6).

The final step is to simplify the fraction 30/6, which simplifies to 5, since 30 divided by 6 equals 5.

Therefore, the answer is 5.

Answer:

Step-by-step explanation:

If you're looking at two triangles, look for the side corresponding to the unknown side. If it's an equilateral (all sides same length) triangle no need to worry. It's probably a scalene, all different lengths, because math is hard. So you'll have 3 different lengthy sides, and you can probably see which ones correspond with which based on length and position. You can use angles to help you.

Now use the sides you have the value of to determine scale factor.

Divide the length of one of the sides on one triangle by the corresponding side on the other. That's your scale factor. Now multiply it by the side that corresponds to the unknown side, and that is supposed to be your length.

A = 78.46

Step-by-step explanation:

55^2 = 50^2 + 35^2 − 2(50)(35)cos(A)

3025 = 2500 + 1225 - 3500 cos A

- 3500 Cos A = -3725 + 3025

-3500 cos A = -700

cos A =  -700/-3500

         = 0.2

A = cos^-1 0.2

A = 78.46

Answer:

A=78.46° (to 4sf)

Step-by-step explanation:

The only way to approach this problem is to solve the equation.

55²=50²+35²-2(50)(35)cos(A)

3025=2500+1225-3500cosA

3025=3725-3500cosA

Now collecting like terms together:

3025-3725=-3500cosA

-700=-3500cosA

CosA=0.2

A=78.46° (to 4sf)
