Answer:
Therefore, option A,B and C cannot be the angles of triangles.
Step-by-step explanation:
Given that total angles in a triangle is 180° so you have to add up all the angles :
Option A,
45° + 45° + 45° = 135° (Not a triangle)
Option B,
60° + 75° + 35° = 170° (Not a triangle)
Option C,
60.5° + 59.5° + 59° = 179° (Not a triangle)
Option C,
65° + 60° + 55° = 180° (It is triangle)
Plot and connect the points A (3, -3), B (-3, -2), C (-5, 1), D (-5, 4), E (-4 ,6), F (-2, 6), G (3, 2), and find the length of EF.
Given:
The points are A(3, -3), B(-3, -2), C(-5, 1), D(-5, 4), E(-4 ,6), F(-2, 6), G(3, 2).
To find:
The length of EF and plot each point on a coordinate plane and connect them.
Solution:
Plot the given point A(3, -3), B(-3, -2), C(-5, 1), D(-5, 4), E(-4 ,6), F(-2, 6), G(3, 2) on coordinate plane and connect them as shown in the below figure.
From the below graph it is clear that the length of EF is 2 units. We can verify this solution by using the distance formula.
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between E(-4 ,6) and F(-2, 6) is
[tex]D=\sqrt{(-2-(-4))^2+(6-6)^2}[/tex]
[tex]D=\sqrt{(-2+4)^2+(0)^2}[/tex]
[tex]D=\sqrt{(2)^2+0}[/tex]
[tex]D=2[/tex]
Therefore, the length of EF is 2 units.

a national park is a rectangle that is 33 miles wide and 56 miles long.how long is a diagonal road through the park
9514 1404 393
Answer:
65 miles
Step-by-step explanation:
The Pythagorean theorem applies.
d^2 = 33^2 +56^2
d^2 = 1089 +3136 = 4225
d = √4225 = 65
The diagonal road is 65 miles long.

Find the area of a pizza with
a 16 in. diameter. If there
are 8 slices, how many sq. in.
is one slice?
Answer:
area of whole pizza = 200.96 in²
area of slice of pizza = 25.12 in²
Step-by-step explanation:
16"/2 = 8" radius
area = πr² = (3.14)(8²) = 200.96 in²
200.96 in²/8 = 25.12 in²

Answer:
The two triangles are congruent, or equal to each other.
Step-by-step explanation:
In order to solve this question, you first need to compare the measurements. Since AB and PQ both equal 4 cm, you know that they are congruent. Since BC and QR are also congruent, you know that the last two have to be congruent as well. Therefore, the triangles ABC and PQR are congruent, or equal, to each other.

The speed s (in miles per hour of a car driving on wet asphalt can be given by s = 3 square root d, where d is the stopping distance (in feet). What is the approximate stopping distance of a car traveling 80 miles per hour? Round your answer to the nearest hundredth.
Answer:
d = 711 miles
Step-by-step explanation:
The speed s of the car is given by :
[tex]s=3\sqrt{d}[/tex] ...(1)
Where
d is the stopping distance
We need to find the stopping distance of a car travelling at 80 mph.
Rearranging equation (1) for d.
[tex]s^2=9d\\\\d=\dfrac{s^2}{9}\\\\d=\dfrac{80^2}{9}\\\\d=711.1\ miles[/tex]
or
d = 711 miles
So, the required stopping distance is 711 miles.

-7b - 4(b + 7) = -3b - 4(b-2)
Answer:
b = -9
Step-by-step explanation:
-7b - 4(b + 7) = -3b - 4(b -2)
First we want to distribute the coefficients across the parentheses. To do so, we multiply the coefficient by every term within the parentheses.
-7b - 4(b + 7) = -3b - 4(b - 2)
-4 • b = -4b
-4 • 7 = -28
-4 • b = -4b
-4 • -2 = 8
Simplify the expression with these new values.
-7b - 4b - 28 = -3b - 4b + 8
Now we want to combine the like terms. First combine the variables.
-7b - 4b - 28 = -3b - 4b + 8
-11b - 28 = -7b + 8
Combine further by adding 7b to both sides.
-4b - 28 = 8
Combine the constants by adding 28 to both sides.
-4b = 36
Isolate b by dividing both sides by -4.
b = -9
This is your answer.
Check your answer by plugging b = -9 back into the original equation.
-7b - 4(b + 7) = -3b - 4(b - 2)
-7(-9) - 4(-9 + 7) = -3(-9) - 4((-9) - 2)
63 - 4(-2) = 27 - 4(-11)
63 + 8 = 27 + 44
71 = 71
Your answer is correct.
Hope this helps!
Answer:
-9 is the required answer of b
Step-by-step explanation:
-7b - 4(b + 7) = -3b - 4(b-2)
open bracket
-7b-4b-28=-3b-4b+8
-11b-28=-7b+8
-11b+7b=28+8
-4b=36
b=36/-4=-9

Answer:
[tex] - (x - 1) {}^{2} + 5[/tex]
Step-by-step explanation:
F(x) is a transformation from h(x).
So our starting equation is
[tex] - (x - 1) {}^{2} - 1[/tex]
F(x) is also facing the same direction h(x) is so we dont have to reflect nothing across the x or y axis.
There isn't a vertical or horizontal stretch, compressions.
There isn't a horizontal shift as the x values stay in the same place.
There is a vertical shift. We can simply move h(x) up 6 units to get to f(x).
So our equation looks like.
[tex] - (x - 1) {}^{2} + 5[/tex]
Maddie does not have any pretzels.
Zach gives abbey 8 pretzels. then he splits half the pretzels he has left with Maddie. Zach let's p represent the number of pretzels he starts with. He finds that the number of pretzels maddie has is 1/2 the difference of p and 8.
write an expression to represent the number of pretzels that maddie has.
Answer:
(p - 8) / 2 = Maddie's pretzels
Amber ran a 25 kilometer road race in 3 hours. She ran at the same speed and covered the same distance each hour. Draw a visual model to find the distance Amber ran each hour. Between which two whole numbers does the she ran each our lie
Answer:
Amber ran 8,333 kilometers during each hour, and the equation to determine that amount is 25/3 = X.
Step-by-step explanation:
Given that Amber ran a 25 kilometer road race in 3 hours, and she ran at the same speed and covered the same distance each hour, to draw a visual model to find the distance Amber ran each hour the following calculation must be performed:
25/3 = X
8.333 = X
So Amber ran 8,333 kilometers during each hour, and the equation to determine that amount is 25/3 = X.
Evan and Dorinda make bracelets for a craft fair. Evan makes 10 bracelets the first day and 8 bracelets each day after that. Dorinda makes 8 bracelets the first day and 8 bracelets each day after that. If they make bracelets for 6 days, how many bracelets will they make in all? a. 567 b. 987653 c. 8765 d.65
Answer:
98 bracelets
Step-by-step explanation:
Number of days, n = 6
Evan:
= 10 + 8(n - 1)
= 10 + 8(6 - 1)
= 10 + 8(5)
= 10 + 40
= 50 bracelets
Dorinda
= 8n
= 8(6)
= 48 bracelets
Total bracelets they will make in all = Evan + Dorinda
= 50 + 48
= 98 bracelets

You have to type up a 400 word paper. If you can type 25
words in 3 minutes, how long will it take you to type the
paper?
Answer:
48 minutes
Step-by-step explanation:
25=3 400/25=16x3=48
Answer:
48 minutes
Step-by-step explanation:
25 words - 3 minutes
400 words - x minutes
Cross multiply
25x = 400 x 3
25x = 1200
Divide both sides by 25
x = 1200/25
x = 48

find the median 60,62,64,54,56,28
Answer:
58
Step-by-step explanation:
you need to order all the numbers together:
28, 54, 56, 60, 62, 64
since the middle 2 are 56 and 60 you need to find the average of those.
(56 + 60)/2 = 58
How many cubic meters of material are there in conical pile of dirt that has radius 9 meters and height 6 meters?Use 3.14 for pi
Answer:
V = 226.08 m³
Step-by-step explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)(πr²)(h).
In this case, r = 6 m and h = 6 m. Thus, the volume of this conical pile is
V = (1/3)(3.14)(6 m)²(6 m), or
V = 226.08 m³
Solve for side c and round to the nearest tenth
Answer:
c
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan64° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{11}{c}[/tex] ( multiply both sides by c )
c × tan64° = 11 ( divide both sides by tan64° )
c = [tex]\frac{11}{tan64}[/tex] ≈ 5.4 ( to the nearest tenth )
