Answer:

1/2 is equivalent to 50%

Step-by-step explanation:

In order to convert a fraction to a percentage you divide the numerator (Top number of a fraction) by the denominator (Bottom number of a fraction), multiply by 100, and add a percentage sign.

So lets try that with our first answer option A) 1/2:

1 divided by 2 = 0.5

0.5 x 100 = 50

50%

So we know that 1/2 is equivalent to 50%

Answer:

z = 65°

y= 105°

Step-by-step explanation:

angle z is adjacent to 115° on a straight line, hence they are supplementary angles, i.e they add up to 180°

hence,

z + 115° = 180°

z = 180° - 115° = 65°  

recall that the sum of angles inside a convex quadrilateral always adds up to 360°

i.e z + y  + 102° + 88° = 360°  (we know z from above)

65 + y +102+88=360

y = 360 -65-102-88 = 105°

Answer:

The x-coordinate of the point of intersection is -2

Step-by-step explanation:

Here we have a typical system of linear equations whose solution will give us both the x- and the y- coordinates (i.e. the intersection point).

Let us solve the system and find which matches the available options, as follow. Given:

[tex]2x+y=1\\9x+3y=-3[/tex]

Taking the first expression and re arranging to solve for [tex]x[/tex] we have:

[tex]2x+y=1\\2x=1-y\\x=\frac{1-y}{2}[/tex]       Eqn.(1)

Plugging in it, in the second expression we then have

[tex]9(\frac{1-y}{2} )+3y=-3\\\\\frac{9}{2}-\frac{9y}{2}+3y=-3\\ \\\frac{9}{2}-\frac{9y}{2}+\frac{6y}{2}=-\frac{6}{2}\\ \\-\frac{9y}{2}+\frac{6y}{2}=-\frac{6}{2}-\frac{9}{2}\\-3y=-15\\y=\frac{-15}{-3}\\ y=5[/tex]

So finally plugging in the y value in Eqn.(1) we have

[tex]x=\frac{1-5}{2} \\x=\frac{-4}{2}\\ x=-2[/tex]

The x-coordinate of the point of intersection is -2

Answer:

Its true.A rectangle is never a rhombus.

Answer:

This is actually false according to most accepted definitions - a rectangle that has equal sides would be a square, and thus also a rhombus.

Step-by-step explanation:

The definition of a rhombus is that it has 4 equal sides.

Also, the definition of a rectangle is that it has two pairs or equal sides, and all angles are 90 degrees.

So a square is a special case of a rectangle. And a square is also a special case of a rhombus.

Meaning that a square is both a rhombus and a rectangle, so any rectangle with equal sides would also be a rhombus.

The x intercept is [tex](\frac{18}{5} , 0)[/tex]

The y intercept is (0, -2)

Solution:

Given equation is:

-5x + 9y = -18

We have to find the y intercept and x intercept

The x-intercept is the point at which the line crosses the x-axis. At this point, the y-coordinate is zero.

The y-intercept is the point at which the line crosses the y-axis. At this point, the x-coordinate is zero

To find the x-intercept of a given linear equation, plug in 0 for 'y' and solve for 'x'.

Substitute y = 0 in given equation

[tex]-5x + 9(0) = -18\\\\-5x = -18\\\\x = \frac{18}{5}[/tex]

[tex]\text{Thus the x - intercept is } (\frac{18}{5}, 0)[/tex]

To find the y-intercept, plug 0 in for 'x' and solve for 'y'

Substitute x = 0 in given equation

[tex]-5(0) + 9y = -18\\\\9y = -18\\\\y = -2[/tex]

Thus the y intercept is (0, -2)

Answer:

Step-by-step explanation:

Total cost for trip = 290 + 50 + 95*5 =290+50+ 475 = $ 815

Savings = $143

Money needed = 815 - 143 = $ 672

No. of driveways = 672/48 = 14

14 driveways must she shovel to have enough money to pay for the trip.

Sneha needs to calculate the total cost of her vacation which is $815. After taking into account her savings, she requires an additional $672. As she earns $48 shoveling each driveway, she would need to shovel 15 driveways.

This is a question of basic algebra and problem solving. Sneha needs to calculate the total cost of her vacation first. She will spend $50 on transportation, $290 on food, and $95 per night for the hotel for 5 nights, or $475 ($95 x 5) for the hotel total.

Adding these amounts together, Sneha's vacation will cost $815 ($50 + $290 + $475). She currently has $143 in savings, meaning she needs $672 more dollars ($815 - $143).

As Sneha earns $48 for each driveway she shovels, we divide the total she needs by the earning for each driveway. That gives us 14 driveways. As Sneha can't shovel a fraction of a driveway, she will need to shovel 15 driveways in total.

To find the length of the train and its speed, we can use the formula Length = Speed x Time. By setting up and solving equations, we can find that the length of the train is 200 meters and the speed of the train is 20 m/s.

To find the length of the train, we can use the formula:

Length = Speed x Time

Given that the train takes 10 seconds to pass you and 30 seconds to pass the bridge, we can calculate:

Length of train = Speed of train x Time taken to pass you = Speed x 10

Length of train + Length of bridge = Speed of train x Time taken to pass the bridge = Speed x 30

Substituting the values, we have:

Speed x 10 + 100 = Speed x 30

Simplifying the equation, we get:

Speed = 400/20 = 20 m/s

Substituting the value of speed back into the first equation, we have:

Length of train = 20 x 10 = 200 meters

Therefore, the length of the train is 200 meters and the speed of the train is 20 m/s.

The volume of the solid rectangular prism with a hole is 444 mm³.

The correct answer is option A.

To find the volume of the solid rectangular prism with a hole, we calculate the volume of the outer rectangular prism and subtract the volume of the inner rectangular prism.

Volume of the Outer Rectangular Prism:

The outer rectangular prism has dimensions 15 mm (length) × 6 mm (width) × 6 mm (height). The volume (V_outer) is given by:

Volume_outer = length × width × height = 15 × 6 × 6 = 540 mm³.

Volume of the Inner Rectangular Prism:

The inner rectangular prism has dimensions 4 mm (length) × 4 mm (width) × the height of the outer prism (6 mm). The volume (V_inner) is given by:

Volume_inner = length × width × height = 4 × 4 × 6 = 96 mm³.

Volume of the Solid Rectangular Prism with Hole:

Subtracting the volume of the inner prism from the volume of the outer prism gives the volume of the solid:

Volume_solid = V_outer - V_inner = 540 - 96 = 444 mm³.

Therefore, the correct volume of the solid rectangular prism with a hole is 444 mm³.

The solution of the system of equations is (-7 , 5)

Step-by-step explanation:

The steps of the linear combination method are:

∵ 2x + 3y = 1 ⇒ (1)

∵ y = -2x - 9

- Add 2x to both sides

∴ 2x + y = -9 ⇒ (2)

Multiply equation (2) by -1 to make the coefficients of x opposites

∴ -2x - y = 9 ⇒ (3)

Add equations (1) and (3) to eliminate x

∴ 2y = 10

Divide both sides by 2

∴ y = 5

Substitute the value of y in equation (1) or (2) to find x

∵ 2x + 5 = -9

- Subtract 5 from both sides

∴ 2x = -14

- Divide both sides by 2

∴ x = -7

The solution of the system of equations is (-7 , 5)

The difference in finishing time between the 2nd and 3rd places is the shortest and it is 0.07 seconds.

Step-by-step explanation:

The first positioned swimmer took 55.98 seconds and the second positioned swimmer took 56.87 seconds to complete the race.

So, the difference is (56.87 - 55.98) = 0.89 seconds.

The second positioned swimmer took 56.87 seconds and the third positioned swimmer took 56.94 seconds to complete the race.

So, the difference is (56.94 - 56.87) = 0.07 seconds.

The third positioned swimmer took 56.94 seconds and the fourth positioned swimmer took 57.17 seconds to complete the race.

So, the difference is (57.17 - 56.94) = 0.23 seconds.

The fourth positioned swimmer took 57.17 seconds and the fifth positioned swimmer took 57.27 seconds to complete the race.

So, the difference is (57.27 - 57.17) = 0.10 seconds.

The fifth positioned swimmer took 57.27 seconds and the sixth positioned swimmer took 57.35 seconds to complete the race.

So, the difference is (57.27 - 57.35) = 0.08 seconds.

The lateral area of the cylinder is approximately [tex]45.24 \, \text{cm}^2\)[/tex] and the volume is approximately [tex]\(45.24 \, \text{cm}^3\)[/tex].

To find the lateral area and volume of a cylinder, you can use the following formulas:

1. Lateral Area [tex](\(A_{\text{Lateral}})\)[/tex]:

[tex]\[ A_{\text{Lateral}} = 2 \pi r h \][/tex]

  where r  is the radius of the base and  h  is the height.

2. Volume (V):

 [tex]\[ V = \pi r^2 h \][/tex]

Given that the diameter (D) is 4 cm, the radius (r) is half of the diameter, so [tex]\( r = \frac{D}{2} = \frac{4}{2} = 2 \)[/tex] cm, and the height (h) is 3.6 cm.

Now, let's calculate:

1. Lateral Area:

 [tex]\[ A_{\text{Lateral}} = 2 \pi \times 2 \times 3.6 \][/tex]

2. Volume:

[tex]\[ V = \pi \times 2^2 \times 3.6 \][/tex]

Calculating these values:

1. Lateral Area:

[tex]\[ A_{\text{Lateral}} \approx 45.24 \, \text{cm}^2 \][/tex]

2. Volume:

[tex]\[ V \approx 45.24 \, \text{cm}^3 \][/tex]

So, the lateral area of the cylinder is approximately [tex]45.24 \, \text{cm}^2\)[/tex] and the volume is approximately [tex]\(45.24 \, \text{cm}^3\)[/tex].
