Congruence of Angles:

Linear angles are those consecutive angles formed when two lines cross. Their sum of linear angles is 180°.

Corresponding angles are those which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are congruent.

From the provided figure, angles y and 3x-60 are linear, thus:

y + 3x - 60 = 180

y = 180 - 3x + 60

y = 240 - 3x

Also, being p and q parallel lines, angles y and 2x+15 are corresponding, thus:

240 - 3x = 2x + 15

Adding 3x:

240 = 2x + 3x + 15 = 5x + 15

Subtracting 15:

240 - 15 =5x = 225

Dividing by 5:

x = 225 / 5 = 45

x = 45°

Point F' is the image when point F is reflected over the line x= -2 and then over the line y = 3.
The location of F' is (3,7).
Which of the following is the location of point F?
A (-7,-1)
B (1,5)
C (1,7)
D (-7,7)

Answers

Answer:

Step-by-step explanation:

1. Graph the points

2. Connect the point 3,7

3. Reflect it over line x=-2 and y=3

THE ANSWER IS A (-7,-1)

The location of the point F should be considered as the option A.  (-7,-1).

Calculation of the location:

Since Point F' is the image when point F is reflected over the line x= -2 and then over the line y = 3. The location of F' is (3,7).

So here we have to do graph the points, then connected the points i.e. 3 and 7. And, then reflect it over the line i.e. x = -2, and y = 3

So here the answer should be (-7,-1)

Answers

9514 1404 393

Answer:

126 children63 adults60 students

Step-by-step explanation:

Let a represent the number of adults that attended. Then 2a is the number of children, and (249 -a -2a) is the number of students. The total revenue is ...

  5(2a) +7(249 -3a) +12a = 1806

  a +1743 = 1806 . . . . simplify; next, subtract 1743

  a = 63 . . . . . . . . adults

  2a = 126 . . . . . . children

  249 -3a = 60 . . students

126 children, 63 adults, and 60 students attended.

If ABC=DEC, C=55, D=65, and B=2x. x=?

Answers

Answer:

X = 30

Step-by-step explanation:

B = E

DEC = 180 degrees/ 65 + E + 55 = 180

E = 60

B = 2x

2x = 60

x = 30

The value of x in the given figure is 32.5.

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

∠C = 55

∠D = 65

∠B = 2x

∠D and ∠B are alternate angles.

Alternate angles are equal.

65 = 2x

x = 65/2

x = 32.5

Thus,

The value of x is 32.5

Lindsey invests $1500 in one account and $900 in an account paying 4 % higher interest. At the end of one year she had earned $204 in interest. At what rates did she invest?

Answers

Answer: She invest 41500 at 7% interest and 900 at 11% interest.

Step-by-step explanation:

Formula for simple interest = [tex]\dfrac{\text{Principal x rate x Time}}{100}[/tex]

Let [tex]P_1=\$1500,\ P_2=\$900\ \ \ \ , r_1=r, \ \ r_2=r+4,\ \ \ t_1=t_2=1[/tex]

Simple interest by first investment = [tex]\dfrac{P_1r_1t_1}{100}=\dfrac{1500(r)(1)}{100}=15r[/tex]

Simple interest by second investment = [tex]\dfrac{P_2r_2t_2}{100}=\dfrac{900(r+4)(1)}{100}=9(r+4)[/tex]

As per given,

Total interest = $204

[tex]\Rightarrow 15r+9(r+4)=204\\\\\Rightarrow\ 15r+9r+36=204\\\\\Rightarrow\ 24r=204-36\\\\\Rightarrow\ 24r=168\\\\\Rightarrow\ r=\dfrac{168}{24}\\\\\Rightarrow\ r=7\%[/tex]

Hence, she invest 41500 at 7% interest and 900 at 11% interest.

Payton uses 1 1/2 cups of vinegar in her salad dressing recipe. How much vinegar would Payton use to make 4 2/3 recipes? Plsssssssssssssssss hurryyyyyyyyyy

Answers

Answer: 3 1/9 cups of vinegar

Step-by-step explanation:

From the question, we are informed that Payton uses 1 1/2 cups of vinegar in her salad dressing recipe.

To know how much vinegar Payton would use to make 4 2/3 recipes, we divide 4 2/3 by 1 1/2. This will be:

= 4 2/3 ÷ 1 1/2

= 14/3 ÷ 3/2

= 14/3 × 2/3

= 28/9

= 3 1/9 cups of vinegar

You are at the store, and are trying to remember how much bread, meat, and cheese you were supposed to buy. The bread costs $1 per loaf, the meat costs $4 per pound, and the cheese costs $3 per pound. You know that you are to buy eight items, that the total cost will be $17, and that you are supposed to purchase three times as much cheese as meat. How many of each do you need to purchase?

Answers

Answer:

4 bread loafs, 1 pound of meat, 3 pounds of cheese

Step-by-step explanation:

Let loaf of bread be b, meat be m and cheese be c

Based on the given, we have following equations:

b + m + c = 8c = 3mb + 4m + 3c = 17

Subtract the first equation from the third and substitute c with m:

b + 4m + 3c - (b + m + c) = 17 - 83m + 2c = 93m + 2(3m) = 99m = 9m = 1

Then

c = 3*1 = 3b = 8 - (1 + 3) = 4

A red-tailed hawk dives at a constant rate in which its altitude changes by -7 ½ meters in 0.15 seconds. How long will it take the hawk to dive -70 meters?

Answers

Answer:

1.4 seconds

Step-by-step explanation:

If the red-tailed hawk dives at a constant rate in which its altitude changes by -7 ½ meters in 0.15 seconds, the rate at which it changes its altitude is thus -7 ½ meters ÷ 0.15 seconds = -7.5 meters ÷ 0.15 seconds = -50 meters per second = -50 m/s.

Now, If the red-tailed hawk dives to a depth of -70 meters, the time it will take to cover that distance is t = distance/rate = -70 m/-50 m/s = 7/5 s = 1.4 s

So, it will take the red-tailed hawk 1.4 seconds to dive to a distance of -70 meters.

Answer:

B: Not proportional

Step-by-step explanation:

This wouldn't be proportional because for you, you are making 22 heartbeats in 20 seconds and 22-20 is 2. But if you look at your friend, he/she is doing 18 heartbeats in 15 seconds so add 5 so that 23 heartbeats is happening in 20 seconds and 23-20 is 3. If we compare, 3 is not the same as 2 making it not proportional.
