Answer 1

Step-by-step explanation:

use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

and therefore also

sin(A)/a = sin(B)/b = sin(C)/c

where the lines and corresponding angles are always opposite of each other.

and remember, the sum of all angles in a triangle is always 180°.

and sin(x) = sin(180-x).

so, we have

sin(32)/43 = sin(B)/53

sin(B) = 53×sin(32)/43 = 0.653156302...

B = 40.77999844...° ≈ 41°

C = 180 - 32 - 40.77999844... = 107.2200016...° ≈ 107°

43/sin(32) = c/sin(107.2200016...)

c = 43×sin(107.2200016...)/sin(32) = 77.507143... ft

≈ 78 ft

B' = 180 - B = 139.2200016...° ≈ 139°

C' = 180 - 32 - 139.2200016... = 8.779998438...° ≈ 9°

43/sin(32) = c'/sin(8.779998438...)

c' = 43×sin(8.779998438...)/sin(32) = 12.38595519... ft

≈ 12 ft

describe a set of transformatios that would map red triangle to the blue triangle

Answers

The set of transformations that would map the red triangle to the blue triangle are translation by 2 units up and 4 units left

How to determine the set of transformations?

From the graph, we have the following highlights:

The red triangle is at the top of the blue triangle by 2 unitsThe red triangle is at the left of the blue triangle by 4 units

This means that the transformation is 2 units up and 4 units left

Hence, the set of transformations that would map the red triangle to the blue triangle are translation by 2 units up and 4 units left

you ordered 7.48 worth of food at sonic before tax . if tax is 7% , how much tax will you pay and whats the total .

Answers

Answer:

Tax = $0.5236

Total = $8

Step-by-step explanation:

$7.48 * 0.07(tax rate) = $0.5236

$0.5236 is the add-on tax you will pay at a rate of 7%

Simply add $0.5236 to your bill before tax of $7.48 to find your total of $8.0036

8.0036 is too low to round to a monetary value, so in total you would pay

Emily to rent a bicycle for 6 hours?

Answers

Answer:

It will cost Emily $40 to rent the bike for 6 hours.

Step-by-step explanation:

SOLUTION:

Total cost equals = (cost per hour × number of hours) + initial bike cost.

Let, y be total cost and x = renting a bicycle for x hours.

y=5x+10

To calculate Emily's cost for 6 hours, let x=6.

y=5(6)+10

y=30+10

y=40

It will cost Emily $40 to rent the bike for 6 hours.

Identify the algebraic description that maps a point (3, 7) onto another point (-5, 7).
A) (x,y) → (x-8, y)
B) (x,y) → (x, y - 8)
C) (x, y) → (x, y + 8)
D) (x,y) → (x+8, y)

Answers

Answer:

A) (x, y) → (x - 8, y)

Step-by-step explanation:

(3, 7) → (-5, 7)

Without adding or subtracting any values, we can immediately tell that the y-value did not change, but the x-value did. With this, we are left with choices A and D.

A) (x, y) → (x - 8, y)

(3, 7) → (3 - 8, y)

(3, 7) → (-5, 7)

This matches our problem, and therefore, A is the correct answer.

Hope this helps!

Answer:

A) (x, y) → (x-8, y)

Explanation:

Present Point: (3, 7)

Future Point: (-5, 7)

The change be: (x, y)

Solve:

(3, 7) + (x, y) → (-5, 7)

change side

(x, y) → (-5, 7) - (3, 7)

simplify the following

(x, y) → (-8, 0)

Therefore, we identify this using (x - 8, y)

2.7% of X equals 50,000. what is X?

don't give fake answers just for points YOU WILL BE REPORTED

Answers

Answer:

x = 1851851.851....

Step-by-step explanation:

Given statement:

2.7% of x equals 50,000.

When we convert the statement into an equation, we get;

⇒ 2.7% × x = 50,000

A percentage is always written as (Percent)/100 in fraction form. Thus;

⇒ 2.7/100 × x = 50,000

Using cross multiplication:

⇒ 2.7 × x = 50,000 × 100⇒ 2.7 × x = 5,000,000

To determine the value of x, we need to isolate it. This can be done by dividing the cooeficient of x both sides.

Divide both sides by 2.7

⇒ (2.7 × x)/2.7 = 5,000,000/2.7⇒ x = 1851851.851....

Answer:

Percent in decimal form:

[tex]\sf 2.7\% = \dfrac{2.7}{100} = 0.027[/tex]

Therefore:

27% of X = 50000

[tex]\sf \implies 0.027 \cdot X=50000[/tex]

[tex]\sf \implies X=\dfrac{50000}{0.027}[/tex]

[tex]\sf \implies X=\dfrac{50000 \times 1000}{0.027 \times 1000}[/tex]

[tex]\sf \implies X=\dfrac{50,000,000}{27}\quad \textsf{(as a fraction)}[/tex]

[tex]\sf \implies X=1,851,852\quad \textsf{(nearest whole number)}[/tex]

Of 20 people who drink coffe 12 don’t put sugar what fraction would represent the people that use sugar in there coffee

Answers

Answer:

Fraction 8/20

Step-by-step explanation:

So only 12 people don't use sugar so if we were to put a fraction for people who don't put sugar then it would be.

12/20

The 20 stands about how many people their are and the 12 stands for how many people don't put sugar.

So now we are supposed ot do peope who put sugar so it would look like this

8/20

How I got the 8 is that I took the 20 people and subtrack it with the people who don't get sugar which is 8 and 8 people use sugar so theirs our answers.

Answers

Answer:20%

Step-by-step explanation:

Solution for 600 is what percent of 3000:

600:3000*100 =

( 600*100):3000 =

60000:3000 = 20

Now we have: 600 is what percent of 3000 = 20

Question: 600 is what percent of 3000?

Percentage solution with steps:

Step 1: We make the assumption that 3000 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that $100%=3000.

Step 4: In the same vein, x%=600.

Step 5: This gives us a pair of simple equations:

$100%=3000(1).

x%=600(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100% / %=3000/600

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100%=600/3000

--->=20%

Therefore, $600 is $20% of $3000.
