Answer: x = 103

Step-by-step explanation:

this is a 90 degree angle indicated by the box in the corner of the angle.

90 degree angles total 90 degrees.

X - 15 + 2 = 90

move the numbers to the other side of the equal sign to isolate the X

by doing the opposite

x = 90 + 15 -2

x = 103

check your work, X - 15 + 2 = 90

103 - 15 + 2 = 90

answer is correct

The volume of the triangular base prism is 120 centimetre cube.

volume of a triangular prism = BH

where

Therefore,

base area = 1 / 2 bh

base area = 1 / 2 × 4 × 6 = 24 / 2 = 12 cm

Hence,

volume of a triangular prism = 12 × 10

volume of a triangular prism = 120cm²

f(x)=2x-3 is more bigger

Here we must write and solve a linear equation to find the number of miles that Arun traveled in the taxi. We will find that Eva traveled 11 miles.

So we know that the taxi charges a fee of $4.10 and then a plus of $0.50 per mile.

So if you travel for m miles, the cost equation is:

C(m) = $4.10 + $0.50*m

Now, we know that for Eva the total fare (total cost) was $9.60, then we need to solve:

$9.60 = C(m) = $4.10 + $0.50*m

$9.60 = $4.10 + $0.50*m

$9.60 - $4.10 = $0.50*m

$5.50 = $0.50*m

$5.50/$0.50 = m = 11

This means that Arun traveled 11 miles in the taxi.

The Eva traveled 25 miles in the taxi.

It is required to find how many miles was the taxi ride.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

The taxi company charged a pick-up fee of $4 plus $4.25 per mile.

The total fare was $110.25.

The cost equation is:

C(m) = $4 + $4.25*m

Now, we know that for Eva the total fare (total cost) was $110.25, then we need to solve:

$110.25 = C(m) = $4 + $4.25*m

$110.25-$4=$4.25*m

$106.25=$4.25*m

m =25

Therefore, the Eva traveled 25 miles in the taxi.

Using the Empirical Rule, it is found that the mean is of 64 inches and the standard deviation is of 3.2 inches.

It states that, for a normally distributed random variable:

The normal distribution is symmetric, hence the mean is given by:

M = (57.6 + 70.4)/2 = 64.

57.6 is two standard deviations below the mean, hence the standard deviation is found as follows:

57.6 = 64 - 2s.

2s = 6.4

The probability that the second ball drawn is black is 4/10 = 2/5

There are two cases. The case where the first ball is red is the first one.

The probability of drawing a red ball is equal to the quotient between the number of red balls and the total number of balls.

p = 3/5

Then, the probability of drawing a black ball in the second attempt is computed in the same way, but because we already drew a ball, now the total number of balls is 4, so we have:

q = 2/4 = 1/2.

So the joint probability is:

P = (3/5)*(1/2) = 3/10.

Then we have the case where both balls are black, the probabilities now are:

p = 2/5

q = 1/4

So the joint probability is:

P = (2/5)*(1/4) = 1/10

The total probability is the sum of the two above:

probability = 3/10 + 1/10 = 4/10.

The probability that the second ball drawn is black is 4/10 = 2/5

Using the discriminant of a quadratic equation, if the graph is translated shifted up 4 units, the graph will have no x-intercepts.

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The discriminant is:

[tex]\Delta = b^2 - 4ac[/tex]

The solutions are as follows:

In this problem, the function is given by:

f(x) = (x + 5)² - 3.

In standard form:

f(x) = x² + 10x + 22.

We want to find coefficient k for which the function has [tex]\Delta < 0[/tex], then:

f(x) = x² + 10x + 22 + k.

The coefficients are a = 1, b = 10, c = 22 + k, hence:

[tex]\Delta < 0[/tex]

10² - 4(22 + k) < 0

100 - 88 - 4k < 0

4k > 12

k > 3.

Hence, with k = 4, the function is shifted up 4 units, and the graph will have no x-intercepts.

Answer:

  133 miles

Step-by-step explanation:

The limited budget gives rise to an inequality that can be solved for the maximum number of miles.

__

The rental cost for m miles will be the sum of the fixed charges and the product of the mileage charge and the number of miles.

  cost = 19.95 +0.15m

We want this to be no greater than 40, so we have the inequality ...

  40 ≥ 19.95 +0.15m

This two-step inequality can be solved in the usual way:

  20.05 ≥ 0.15m . . . . . step 1, subtract 19.95 from both sides

  133.667 ≥ m . . . . . . . step 2, divide by the coefficient of the variable

The maximum whole number of miles Gabrielle can drive is 133.
