Triangle ABC and Triangle DEF are similar. Find the unknown measures. (t = ? and u = ?)

Answer: 7.0

Step-by-step explanation: Tan 29 = x/8 than you multiple 8 by tan 29 and you will get 7.0

The Length of BC is 4.4.

The branch of mathematics concerned with specific functions of angles and their application to calculations. In trigonometry, there are six functions of an angle that are often utilised. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their names and acronyms (csc).

Given:

B = 8

Using Trigonometry

tan 29 = P/ B

0.554 = P / 8

P = 8 x  0.554

P = 4.432

Hence, the measure for BC is 4.432

Answer:

The cost of the mug is of $6.50.

Step-by-step explanation:

The cost of the mug and r refills is given by the following equation:

[tex]C(r) = 2.3r + 6.5[/tex]

Cost of the mug:

The cost of the mug is found when no refills are bought, that is, C when [tex]r = 0[/tex], which is [tex]C(0)[/tex]

[tex]C(0) = 2.3*0 + 6.5 = 6.5[/tex]

Answer:

The height of the taller tree is 7.5 feet.

Step-by-step explanation:

I am going to say that:

The height of the shorter tree is x.

The height of the taller tree is y.

The height of shorter tree is 3/5 of the height of the taller tree.

This means that [tex]x = \frac{3y}{5}[/tex]

If the height of the shorter tree is 4 1/2 feet tall, what is the height, in feet, of the taller tree? ​

This means that [tex]x = 4 + \frac{1}{2} = \frac{8+1}{2} = \frac{9}{2}[/tex]

We want to find y.

[tex]x = \frac{3y}{5}[/tex]

[tex]\frac{9}{2} = \frac{3y}{5}[/tex]

[tex]6y = 45[/tex]

[tex]y = \frac{45}{6}[/tex]

[tex]y = 7.5[/tex]

The height of the taller tree is 7.5 feet.

Answer:

10.26 bags

Step-by-step explanation:

Area of circle :

A = πr²

radius, r = 7ft

A = π * 7²

A = π * 49

A = 153.93804 ft²

Since a bag covers 15 ft² ;

Number of bags needed will be :

Area / number of square feet per bag

153.93804 ft² / 15 ft²

= 10.262536 bags

= 10.26 bags

Answer:

56

Step-by-step explanation:

The pattern is an arithmetic sequence:

by the first three terms, the common difference is:

28-14=42-28=14

So the next pattern would be:

14+42=56

By the equation x = a + d ( n - 1 )

Substituting when n=1, x=14 and when n=2 x=28

a = 14 and d = 14

x = 14 + 14 ( n - 1 )

substituting n = 4

x = 14 + 14 ( 4 - 1 )

x = 56

28÷14=42-28=14+42=56

Answer: b) $60.56 per year of age

Step-by-step explanation: If the scatterplot of two variables shows a line and the correlation between them is strong, we can calculate a regression line.

Regression line is a line graph that best fits the data. Like any other line, its formula is given by

y = mx + b

with

m being the slope

b the y-intercept

The slope of the line, correlation and standard deviations of the two variables have the following relationship:

[tex]m=r\frac{S_{y}}{S_{x}}[/tex]

where

r is correlation

[tex]S_{y}[/tex] is standard deviation for the y data

[tex]S_{x}[/tex] is standard deviation for the x data

For our problem:

r = 0.34

[tex]S_{y}=[/tex] 2850

[tex]S_{x}=[/tex] 16

Calculating

[tex]m=0.34(\frac{2850}{16})[/tex]

m = 60.56

Slope for the regression line of annual income per year of age is 60.56.

Answer:

  61

Step-by-step explanation:

75 = 10×7 +5

500 = 71×7 +3

All the multiples of 7 between the 10th and the 71st (including the 71st, but not the 10th) are numbers in the range that are divisible by 7.

61 numbers in the interval [75, 500] are divisible by 7.

The value of x would be 11.

Step-by-step explanation:

We can simply just isolate x in the equation to solve:

2x + 40 = 62

(Subtract 40 from both sides) 2x = 22

(Divide each side by 2) x = 11

Hope this helps! :)

============================================================

Explanation:

If we knew the value of x, we would use PEMDAS to evaluate 2x+40 to get some single number value. For instance, if x = 4, then 2x+40 becomes 2(4)+40 which evaluates to 48 when you use PEMDAS.

However, we don't know the value of x. To find x, we follow PEMDAS in reverse to undo everything happening to x.

Note the order in which stuff is happening to x

To undo this, we follow this process in reverse. So we need to undo the "add 40" part first, which was the last thing done. That means we'll subtract 40 from both sides

2x+40 = 62

2x+40-40 = 62-40

2x = 22

Then we undo the "multiply by 2" part. We'll divide both sides by 2

2x = 22

2x/2 = 22/2

x = 11

Let's check the answer.

2x+40 = 62

2(11)+40 = 62 ... x replaced with 11

22+40 = 62

62 = 62

Since we get the same thing on both sides, we get a true equation and this confirms we have the correct x value.

Answer:

  b.  -√3/3

Step-by-step explanation:

From your knowledge of the values of trig functions of special angles, you know sin(30°) = 1/2. For an angle in the second quadrant, this means the reference angle is 30° and the actual angle measure is 180° -30° = 150°.

The corresponding value of the tangent function is -√3/3, negative in the second quadrant.

Answer:

sin theta=p/h=1/2 let p=1k and h=2k

tan theta=p/b=1k/(√(2k)²-k²)=1k/k√3=1/√3

=tan 30

therefore theta =30°

your answer is 1/√3=√3/3

C A/H....adjacent over hypotenuse

Answer:

Well, I got B. Because it seems the most reasonable answer to this question.

Step-by-step explanation:

Answer:

Account balance after interest is added : A = P(1 + rt)

Interest : I = A - P

R = 2.7% per year

P = $900.00

t = 1.5 years

First, converting R percent to r a decimal

r = R/100 = 2.7%/100 = 0.027 per year.

Solving our equation:

A = 900(1 + (0.027 × 1.5)) = 936.45  

A = $936.45

Interest : I = A - P = $36.45
