If triangle CFH is similar to triangle TDM with a scale factor of 4: 5 find the perimeter of CFH

Answer:

BC = 6.7 cm (rounded to nearest tenth)

Explanation:

Given: ABC is a right triangle with right angle C as shown below.

Side AB=18 cm and m∠A=22°.

Using Sine ratio in triangle ABC to find BC.

Sine ratio is defined as the ratio of the opposite side of a right triangle to the hypotenuse.

i.e

[tex]\sin A = \frac{Opposite side}{Hypotenuse side}[/tex]

Let BC = x (opposite side) and AB = 18 cm(Hypotenuse side)

then;

 [tex]\sin 22^{\circ} = \frac{x}{18}[/tex]

[tex]0.37460659341 = \frac{x}{18}[/tex]

Multiply both sides by 18 we get;

[tex]x = 0.37460659341 \times 18 = 6.74291868[/tex]

therefore, value of BC (nearest tenth place) is, 6.7 cm

Answer:

36 ft

Step-by-step explanation:

So the proportion of the big triangle is 48:4 or 12:1. So if the small triangle’s height is 3 feet, then 3*12 is 36 feet.

Answer: 36 ft

Step-by-step explanation:

Similar triangles means there is a constant proportion between the left legs, the base legs, and the hypotenuses.

[tex]\frac{LeftLeg(large)}{LeftLeg(small)}= \frac{BaseLeg(large)}{BaseLeg(small)}[/tex]

                  [tex]\frac{x}{3}= \frac{48}{4}[/tex]

Cross multiply: x(4) = 3(48)

solve for x:        ÷4     ÷4    

                          x    =  3(12)

                                =  36

Answer:

[tex]10\dfrac{2}{7}\ miles[/tex]

Step-by-step explanation:

If Kevin walked his dog 1 2/7 miles and Sam walked his dog 7 times as far, then Sam walked his dog

[tex]1\dfrac{2}{7}\cdot 7=\dfrac{1\cdot 7+2}{7}\cdot 7=\dfrac{9}{7}\cdot \dfrac{7}{1}=9\ miles.[/tex]

Together they walked

[tex]1\dfrac{2}{7}+9=10\dfrac{2}{7}\ miles.[/tex]

The student that solved at a rate of 28 per minutes was Logan

Answer:

Logan

Answer:

Logan solved problems at a rate of 28 problems per minute.

Step-by-step explanation:

To find the number of problems per minute that a person solved, you will divide the number of problems that they solved by the number of minutes that they took.

Murray:

58 problems in 2 minutes,

58 / 2 = 29

He solved problems at a rate of 29 problems per minute.

Kris:

78 problems in 3 minutes,

78 / 3 = 26

He solved problems at a rate of 26 problems per minute.

Logan:

84 problems in 3 minutes,

84 / 3 = 28

He solved problems at a rate of 28 problems per minute.

Since you found that Logan solved problems at a rate of 28 problems per minute, Logan is the student that solved problems at a rate of 28 per minute.

The equation representing the total cost after buying x slices of pizza

is [tex]\( C(x) = E + x \times P \)[/tex].

Let's denote the entrance fee as E (in dollars) and the cost of each slice of pizza as P (also in dollars). Given the problem, we can write the following equations based on the given information:

After having 1 slice of pizza, the total cost is $6:

[tex]\(E + 1 \times P = 6\)[/tex]

After having 2 more slices of pizza (total 3 slices), the total cost is $10:

[tex]\(E + 3 \times P = 10\)[/tex]

To find the equation that represents the total cost (y) after buying x slices of pizza (let's call it C(x), we need to generalize the pattern observed in the given equations.

Notice that the entrance fee remains constant regardless of the number of slices of pizza bought. So, we can write the equation as:

[tex]\[ E + x \times P = C(x) \][/tex]

Substituting the values given in the problem:

[tex]\[ C(x) = E + x \times P \][/tex]

So, the equation representing the total cost after buying x slices of pizza

is [tex]\( C(x) = E + x \times P \)[/tex]. This equation gives the total cost (y) as a function of the number of slices of pizza bought (x).

The perimeter of the rectangle is 42m.

To find the perimeter of the rectangle, we need to know the lengths of its sides. From the given information, we know that the area of the rectangle is 108m^2 and its diagonal is 15m. We can use this information to find the lengths of the sides.

Let the length of the rectangle be 'l' and the width be 'w'.
Given, lw = 108 and sqrt(l^2 + w^2) = 15.
Squaring both sides of the second equation, we get l^2 + w^2 = 225.
Since lw = 108, we can solve the quadratic equation l^2 - 108l + 225 = 0 to find l. In this particular case, the quadratic factors as (l - 9)(l - 12) = 0, so l = 9 or l = 12.
Substituting the values of l in the equation lw = 108, we find w = 12 or w = 9.
Since the perimeter is the sum of all the sides, the perimeter of the rectangle is (2l + 2w) = (2 * 9 + 2 * 12) = 42m.

Step-by-step explanation:

[tex]\int 3x(x^2+3)^4 \ dx[/tex].

It is apparently obvious we could expand the bracket and integrate term-by-term. This method would work but is very time consuming (and you could easily make a mistake) so we use a different method: integration by substitution.

Integration by substitution involves swapping the variable [tex]x[/tex] for another variable which depends on x: [tex]u(x)[/tex]. (We are going to choose [tex]u[/tex] for this question).

The very first step is to choose a suitable substitution. That is, an equation [tex]u=f(x)[/tex] which is going to make the integration easier. There is a trick for spotting this however: if an integral contains both a term and it's derivative then use the substitution [tex]u=\text{The Term}[/tex].

Your integral contains the term [tex]x^2 + 3[/tex]. The derivative is [tex]2x[/tex] and (ignoring the constants) we see [tex]x[/tex] is also in the integral and so the substitution [tex]u=x^2+3[/tex] will unravel this integral!

Step 2: We must now swap the variable of integration from x to u. That means interchanging all the x's in the integrand (the term being integrated) for u's and also swapping (dx" to "du").

[tex]u=x^2+3 \Rightarrow \frac{du}{dx}=2x \Rightarrow dx = \frac{1}{2x} du[/tex]

Then,

[tex]\int 3x(x^2+3)^4 \ dx = \int 3x \cdot u^4 \cdot \frac{1}{2x} du = \int \frac{3}{2}u^4\ du[/tex].

The substitution has made this integral is easy to solve!

[tex]\int \frac{3}{2}u^4\ du= \frac{3}{10}u^5 + C[/tex]

Finally we can substitute back to get the answer in terms of x:

[tex]\int 3x(x^2+3)^4 \ dx = \frac{3}{10}(x^2+3)^5+C[/tex]

An acrostic poem for the word 'percent' is crafted with each line pertaining to the process and concept of calculating percents, expressed as a part of 100, or ratios with a denominator of 100.

Explanation:

An acrostic poem for the word percent could be:

Perusing numbers, calculations at hand,

Every figure is neatly planned.

Ratios and fractions - they all fit,

Calculations to make you think a bit.

Each part of a hundred, clearly set,

Numerical values that we get,

Twenty, fifty, seventy-five, all to percent we convert and drive.

This acrostic poem takes the word percent and creates a line for each letter that relates to the concept of percentages, which are ratios with a denominator of 100. Calculating percents involves setting up equivalent fractions or converting to decimals and fractions for ease of use in various mathematical situations. An understanding of this concept is essential for mathematical proficiency.

Assuming that we are solving in terms of n.

Start by distributing:

2(n + 5)

(2*n) + (5*2)

2n + 10 = -2

Subtract 10 to start toward isolating your variable:

2n = -12

Divide by two to finish solving:

n = -6

Answer:

n=-6

Step-by-step explanation:

2(n+5)=-2

distribute the 2 to the numbers in the parentheses:

2n+10=-2

Get the n factor alone, subtract 10 from both sides:

2n=-12

Now you just want the n alone so you are going to use the inverse operation on 2n to both sides: 2n/2=-12/2

n=-6

Step-by-step explanation:

Since we are rounding to the 2, we will look at the digit after it

4 < 5 so we leave the 2 alone

.424 is rounded to .42

Answer:

0.42 is your answer

Step-by-step explanation:

The underlined number is 2. Look at the place value to the right. It is a 4. Because 4 is less than 5, round down.

0.424 rounded to the nearest hundredth place is 0.42

We have the supplementary angles.

The sum of the measures of the two Supplementary Angles is 180°.

Therefore we have the equation:

13x - 2 + 39 = 180

13x + 37 = 180     subtract 37 from both sides

13x = 143      divide both sides by 13

x = 11

simplify to get 1/3 times 17/4 which simplifies to 17/12 or 1 and 5/12.

Answer:

17/12

Step-by-step explanation:

1/3 x 4 1/4 change to

1/3 x 17/4

multiply the top and then the bottom : 17/12

Step-by-step explanation:

We are given the co-ordinates,

x : -2, -1, 0, 1, 2

y : 8, 5, 2, -1, -4

According to the graph, we see that this function represents a straight line.

The general form of the straight line is y = mx + c, where m is the slope and c is the y-intercept.

So, taking any two points we will find the equation of the straight line.

Consider, (0,2) and (1, -1). Now, slope is given by,

m = [tex]\frac{-1-2}{1-0}[/tex]

i.e. m = -3

Now, we will find the y-intercept of this equation using (0,2) and m = -3,

i.e. y = -3x + c

i.e. 2 = c

Hence, the equation of the straight line is y = -3x + 2.

Answer:

It would be C

To rewrite the inequality 5x - 5y ≥ 70 in slope-intercept form, we solve for y by subtracting 5x from both sides and then dividing by -5, resulting in y ≤ x - 14, with a slope of 1 and a y-intercept of -14.

The question is asking to rewrite the inequality 5x - 5y ≥ 70 in slope-intercept form. The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. To convert the given inequality into this form, we need to solve for y.

Steps to rewrite the inequality in slope-intercept form:

The inequality in slope-intercept form is y ≤ x - 14. The slope is 1 and the y-intercept is -14.
