Answer:

x = 7

Step-by-step explanation:

Parallel sides have to be the same length

5x+3 = 38

Subtract 3 from each side

5x+3-3 = 38-3

5x = 35

Divide by 5

5x/5 = 35/5

First, we need the place value of each digit:

\(8-> Tens -> 10\\0-> Units->1\\1-> Tenths->0.1\\0->Hundredths->0.01\\6-> Thousandths->0.001\)

Next, we multiply each digit by its place value, to give the expanded form;

Answer:

The possible number of students in Mrs. Hayko's class is limited to 15 or 30, as higher multiples of 15 would exceed the desired class size.

Step-by-step explanation:

a)

Let 'x' be the total number of students in Mrs. Hayko's class.

One-third of the students walk to school: (1/3)x.

The remaining students who do not walk to school: (2/3)x.

Four-fifths of the non-walking students take the bus: (4/5) * (2/3)x.

Simplify to find the fraction of students taking the bus: (8/15)x.

b)

Consider different values for 'x' to find a whole number of students taking the bus.

Start with a small number, such as x = 15.

Calculate the number of students taking the bus using (8/15)x.

If the result is a whole number, it's a possible class size.

Repeat with different values of 'x' until a whole number is obtained.

The possible number of students in Mrs. Hayko's class could be 15, 30, or any other multiple of 15.

The tip of the minute hand on a clock travels approximately 26.4 cm in 11 minutes if the minute hand is 23 cm long.

What is Circle?

A circle is a two-dimensional geometric shape that is defined as the set of all points in a plane that are a fixed distance away from a given point, called the center of the circle. This distance is known as the radius of the circle.

A circle can also be defined as the locus of a point that moves in a plane in such a way that its distance from a fixed point is constant. The constant distance is the radius of the circle.

The minute hand on a clock makes a full rotation in 60 minutes, which means it travels the circumference of a circle with a radius of 23 cm in 60 minutes. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle, and π is a mathematical constant approximately equal to 3.14.

Therefore, the circumference of the circle traced by the tip of the minute hand is:

C = 2πr = 2 × 3.14 × 23 cm ≈ 144.44 cm

To find out how far the minute hand travels in 11 minutes, we need to calculate what fraction of the circumference it covers in that time. Since 11 minutes is about 18.3% of an hour (60 minutes), the minute hand travels 18.3% of the circumference of the circle in that time:

Distance traveled = 0.183 × 144.44 cm ≈ 26.4 cm

Therefore, the tip of the minute hand on a clock travels approximately 26.4 cm in 11 minutes if the minute hand is 23 cm long.

Answer:

Step-by-step explanation:

Given functions are

y = 5 cos ( 2π / 3 ) t

y = 5 cos ( 4π / 3 ) t

y= 10 cos ( 2π / 3 ) t

y = 10 cos ( 4π / 3 ) t

The pendulum half oscillation from left extreme to right extreme takes 1.5 s

So its time period of oscillation T = 1.5 x 2 = 3 s .

standard equation of oscillation is

y = A cos ω t where A is amplitude and ω is angular frequency .

Amplitude of oscillation A = 10 / 2 = 5 inch .

Among the given equation of motion only first two has amplitude equal to 5 . So both the last two are ruled out .

The angular frequency of first motion as per given equation

ω = 2π / 3

If time period is T

2π / T = 2π / 3

T = 3 s

So it matches with the time period of oscillation of pendulum .

Hence the first equation truly represents the oscillation of pendulum.

The function models the horizontal displacement as a function of time in seconds is  \(\rm y = 10 sin(\dfrac{2\pi}{3})t\)  and this can be determined by using the given data.

Given :

It takes 1.5 seconds for a grandfather clock's pendulum to swing from left (initial position) to right, covering a horizontal distance of 10 inches.

For the oscillation the standard equation is given below:

\(\rm y = A\;cos \;\omega t\)

where A is the amplitude, \(\omega\) is the angular velocity, and t is the time.

Now, determine the time period that is:

T = 1.5 \(\times\) 2

T = 3sec

Now, the angular frequency is given by:

\(\omega = \dfrac{2\pi}{3}\)

So, the function models the horizontal displacement as a function of time in seconds is given below:

\(\rm y = 10 sin(\dfrac{2\pi}{3})t\)

Therefore, the correct option is C).

The other trinomial is 2x²-5x-3

We are given the sum of two trinomials as 7x²-5x-4, and one of the trinomials is 3x²+2x-1.

We are asked to find the other trinomial.

The sum of two trinomials can be calculated by adding their corresponding coefficients.

Therefore, we can write the following equation:

3x²+2x-1+ ax²+bx+c = 7x²-5x-4

Combining like terms and equating the corresponding coefficients of x², x and the constants, we get:

3x²+ax² = 7x²(3+a)x²

= 7x²-3x+1+bx

= -5x(2+b)x

= -5x-1+c = -4c = -4+1 = -3

Answer:

I think the answer is 12t

(a) The cost of 1 kg of turnips is £71.95, and

(b) The cost of 1 kg of mushrooms is £89.50.

To solve this problem, let's assign variables to the unknowns.

Let the cost of 1 kg of mushrooms be 'm' and the cost of 1 kg of turnips be 't'.

According to the given information:

Equation 1: 2m + 2.5t = 8.55

Equation 2: 3m + 4t = 13.10

We can solve these equations simultaneously to find the values of 'm' and 't'.

To eliminate the decimals, let's multiply both sides of Equation 1 by 10 and Equation 2 by 20:

20m + 25t = 85.50

60m + 80t = 262.00

Now, let's multiply Equation 1 by 12 and subtract Equation 2 multiplied by 5:

240m + 300t - (60m + 80t) = 1026.00 - 1310.00

180m + 220t = -284.00

We have a new equation:

180m + 220t = -284.00 ---(3)

Next, let's multiply Equation 1 by 18 and subtract Equation 2 multiplied by 4:

36m + 45t - (60m + 80t) = 154.35 - 524.00

-24m - 35t = -369.65

We have another new equation:

-24m - 35t = -369.65 ---(4)

Now, we have a system of linear equations with two variables. Let's solve this system by eliminating one variable.

Multiply Equation 3 by 35 and Equation 4 by 220:

6300m + 7700t = -9940.00 ---(5)

-5280m - 7700t = -81323.00 ---(6)

Adding Equations 5 and 6, we eliminate 't':

1020m = -91263.00

m = -91263.00/1020

m = -89.50

Substituting the value of 'm' back into Equation 3:

180(-89.50) + 220t = -284.00

-16110 + 220t = -284.00

220t = -284.00 + 16110

220t = 15826.00

t = 15826.00/220

t = 71.95.

The correct answer is D) a night that is longer than a certain length.

Short-day plants, also known as long-night plants, require a period of uninterrupted darkness or a night that is longer than a specific critical length in order to flower. These plants have a photoperiodic response, meaning their flowering is influenced by the duration of light and dark periods in a 24-hour day.

Short-day plants typically flower when the duration of darkness exceeds a critical threshold. This critical length of darkness triggers a series of physiological processes within the plant that eventually lead to flowering. If the night length is shorter than the critical threshold, the plant will not flower or may have delayed flowering.

It's important to note that short-day plants are not necessarily restricted to only flowering under short days. They can still flower under longer days, but the critical factor is the length of uninterrupted darkness they receive.

Hence the correct answer is D.
