The triangle below is isosceles. Find the length of side x to the nearest tenth.

Answer:

The list of rational numbers below are ordered from greatest to least.

15, 6.7, , 100%, -55%,

To determine which of the following numbers could NOT be the missing value in the list above, we need to determine the correct order of the numbers in the list.

First, we can convert the percentages to decimals:

100% = 1

-55% = -0.55

Now we can order the numbers from greatest to least:

15, 6.7, 1, -0.55, x

We know that x is a rational number, so it can be expressed as a fraction. We can eliminate answer choices C and D because they are not rational numbers.

Next, we can compare x to the other numbers in the list. We know that x must be less than 6.7, so we can eliminate answer choice A.

That leaves us with answer choice B, -2.5. This number could be the missing value in the list, so the answer is B.

The lower quartile of the given data set is 63.

To find the lower quartile (Q1), we need to determine the value that divides the data set into the lower 25% of the values.

First, we need to sort the data set in ascending order: 61, 61, 62, 64, 66, 69, 69, 70, 72, 73, 74, 78.

Next, we calculate the position of the lower quartile using the formula: (n+1)/4, where n is the number of data points. In this case, we have 12 data points, so (12+1)/4 = 13/4 = 3.25.

Since 3.25 is not a whole number, we can find the lower quartile by taking the average of the data points at positions 3 and 4.

The data point at position 3 is 62, and the data point at position 4 is 64.

Therefore, the lower quartile (Q1) is the average of 62 and 64:

(Q1) = (62 + 64)/2 = 126/2 = 63.

Hence, the lower quartile of the given data set is 63.

Step-by-step explanation:

The nearest tenth, the surface area of the given cylinder is approximately 175.9 cm².

To find the surface area (SA) of a cylinder, we need to calculate the sum of the lateral surface area (arl) and the base area (B).

The formula for the lateral surface area of a cylinder is given by:

arl = 2πrh,

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

The formula for the base area of a cylinder is given by:

B = πr^2.

Let's calculate the values:

Given:

Height (h) = 5 cm

Radius (r) = 4 cm

First, we calculate the lateral surface area (arl):

arl = 2πrh

= 2 * 3.14159 * 4 cm * 5 cm

≈ 125.66368 cm²

Next, we calculate the base area (B):

B = πr^2

= 3.14159 * (4 cm)^2

≈ 50.26544 cm²

Finally, we find the surface area (SA):

SA = arl + B

≈ 125.66368 cm² + 50.26544 cm²

≈ 175.92912 cm²

Rounded to the nearest tenth, the surface area of the given cylinder is approximately 175.9 cm².

The zero of f is x = -2. C.

The equation of the linear function can be found using the point-slope formula:

y - y1 = m(x - x1)

m is the slope and (x1, y1) is a point on the line.

Plugging in the given values, we get:

y - 4 = 4(x + 1)

Expanding and simplifying, we get:

y = 4x + 8

The zero of f (where f(x) = y) set y = 0 and solve for x:

0 = 4x + 8

4x = -8

x = -2

The point-slope formula may be used to determine the equation of the linear function:

y - y1 = m(x - x1)

(X1, Y1) is a point on the line, and m is the slope.

With the above variables obtain:

y - 4 = 4(x + 1)

a = (y₂ - y₁)/(x₂ - x₁)

Here we can use the first two points on the table:

Then the slope is:

a = (29 - 51)/(-5.5 + 11)

a = -4

The boy will take approximately 64.5 minutes to walk to school if he was previously taking 43 minutes.

Using the concept of proportionality to determine the new time it will take for him to walk to school.

Let's denote:

d1 = Distance he was walking previously

t1 = Time he took previously

d2 = New distance he has to walk

t2 = New time it will take

From the given information, we know that:

d2 = 1.5 * d1

t1 = 43 minutes

Since distance and time are directly proportional, we can set up a proportion:

d1 / t1 = d2 / t2

Substituting the given values:

d1 / 43 = (1.5 * d1) / t2

To solve for t2, we can cross-multiply and solve for it:

d1 * t2 = (1.5 * d1) * 43

t2 = (1.5 * d1 * 43) / d1

Simplifying the expression:

t2 = 1.5 * 43
