Name 2 decimals with a difference of 0.35.

Answer:

170.27

Step-by-step explanation:

The value of speed rounded to the nearest tenth of a mile per hour is,

⇒ 170.3 miles per hour.

We have to give that,

The winning speed in the 2011 Indianapolis 500 was 170.265 miles per hour.

Here, The speed is,

⇒ 170.265 miles per hour.

We can round to the nearest tenth of a mile per hour as,

Here, 6 is greater than 5.

Hence,

⇒ 170.265 miles per hour.

⇒ 170.3 miles per hour.

To solve the given polynomial addition and subtraction question, combine like terms. The z4 terms combined are -7z4 and the z2 terms are 5z2, resulting in the simplified expression 5z2 - 7z4.

To add or subtract the polynomials 7z2 − 2z4 − 2z2 − 5z4, you'll want to combine like terms. Like terms are terms that have the same variables raised to the same power.

Here, z2 and z4 are like terms, so you can combine them separately.

Starting with the z4 terms:
-2z4 and -5z4 combine to give you -7z4. They both have the same variable z raised to the fourth power, so you just add the coefficients, keeping the exponent the same.

Then, combine the z2 terms:

7z2 and -2z2 combine to give you 5z2.

Similarly, these terms have the same variable z raised to the second power.

Now, putting it all together, you get:

5z2 − 7z4

This is the simplified version of the polynomial after combining like terms.

Answer:

180000 m/s

Step-by-step explanation:

The frequency of the wave is 900 Hz.

The wavelength of the wave is 200 m.

The speed of a wave is given as the product of wavelength and frequency. That is:

v = λf

where λ = wavelength

f = frequency

The speed of the wave is therefore:

v = 200 * 900 = 180000 m/s

The speed of the wave is 180000 m/s.

Answer:270,000

Step-by-step explanation:

The 7 is the 10 thousandths so the next number over you. Round

To round 271,403 to the nearest ten thousand, we need to look at the digit in the ten thousand place, which is the 4. If the digit in the ten thousand place is 5 or greater, we round up; if it is less than 5, we round down. In this case, the digit is 4, so we round down. The answer is 270,000 since we round to the nearest ten thousand.

Answer:

3 minutes 42 seconds

Step-by-step explanation:

Half of 7 minutes is 3 minutes 30 seconds

half of 24 seconds is 12 seconds

Add this together

3 minutes 30 seconds + 12 seconds = 3 minutes 42 seconds

Answer:

3 minutes and 42 seconds

Step-by-step explanation:

1 minute=60 seconds, so 7minutes =420 seconds, add the extra 24 seconds to get 444 seconds. Half of that is 222seconds which is equal to 3 minutes and 42 seconds

Image is missing, so i have attached it.

Answer:

AC = 10sin 40°

Step-by-step explanation:

From the diagram attached, using terms in trigonometric ratio, AC is the opposite side, BC is the adjacent side and AB is the hypotenuse.

Thus, since we want to find AC;

We know that in trigonometric ratios; opposite/hypotenuse = sin θ

In the diagram, θ = 40° and AB = 10

Thus,

AC/10 = sin 40°

Multiply both sides by 10 to get;

AC = 10sin 40°

First, let's rearrange the first equation so we can know what y equals to.

So, (x - y = 2) becomes (y = x - 2).

Now, we can plug this into the second equation so we can find x.

6x + 4(x - 2) = 92

6x + 4x - 8 = 92

10x - 8 = 92

10x = 100

x = 10

Now that we know x equals 50, we can plug this into either equations to find y. Let's use the first equation.

10 - y = 2

-y = -8

y = 8

Now, let's check our work by plugging int eh values of x and y for both equations.

First equation:

10 - 8 = 2

Second equation:

6(10) + 4(8) = 92

60 + 32 = 92

So, the values of x and y are correct.

Answer:

A) an upper quartile of 56 and a median of 50

Step-by-step explanation:

Hello!

The lower and upper ends "box" from the box and whiskers plot is determined by the first (Q₁) and third (Q₃) quartiles of the data set and the line inside the box marks the median or second quartile of the sample (Q₂)

The length of the whiskers of the diagram is determined by the minimum value (left whisker) and the maximum value (right whisker)

If you observe the graphic:

Q₁= 42

Q₂= 50 (Median)

Q₃= 56

Min= 38

Max= 66

The box is delimited by a lower quartile of 42 and an upper quartile of 56, with a median 50, the least observation is 38 and the highest observation is 66.

The correct choice is A.

Answer:

5-3w=l

Step-by-step explanation:

Answer:

For the first one q is 134

And the second one is t is 8.8

Step-by-step explanation:

That is true cause 134 +166 = 300

and, 14.2 = 8.8 - 5.4.

Please Mark brainliest!

For the equations given, the value of q is found to be 134 after subtracting 166 from both sides, and the value of t is calculated as 19.6 by adding 5.4 to both sides.

To solve the first equation, q + 166 = 300, we need to isolate the variable q by subtracting 166 from both sides of the equation:

q + 166 - 166 = 300 - 166

q = 134

So, the value of q is 134.

For the second equation, 14.2 = t - 5.4, we need to isolate the variable t by adding 5.4 to both sides of the equation:

14.2 + 5.4 = t - 5.4 + 5.4

t = 19.6

Thus, the value of t is 19.6.

Answer:

Between 75 and 98.

Step-by-step explanation:

Let's first have a look at the previous data available:

Friday, 27 dunk teachers out of 215 participants (12.5%)

Saturday: 54 dunk teachers out of 417 participants (12.9%)

Sunday: 39 dunk teachers out of 368 participants (10.6%)

So, based on the previous 3 days, she can expect between 10% and 13% will dunk a teacher.

If she has 750 contestants on Monday, the number of winners should then be in the range of 75 (10% of 750) and 98 (13% of 750).

To eliminate x, we need to make the coefficient of x the same in both equations. We achieve this by multiplying Equation I and Equation II by certain numbers. Subtraction of the modified equations then eliminates x, leaving one equation with y.

To eliminate the variable x in the system of equations, we need to multiply each equation by a number that would make the coefficients of x in both equations equal, such that they cancel each other out when we add or subtract the equations.

For the given equations: Equation I: 5x + 3y = 19 and Equation II: 2x - 4y = -8, we can multiply Equation I by 2 and Equation II by 5.

This will result in:

Equation I: 10x + 6y = 38 and Equation II: 10x - 20y = -40

By subtracting Equation II from Equation I, we are able to eliminate the x variable, resulting in the equation 26y = 78.
