Find the Missing Angle)
Answer:
110-degrees
Step-by-step explanation:
these are alternate exterior angles which are equal *congruent
Answer:
Since 110° and ? are alternate exterior angles, take the 110° and subtract 180°. Remember, 180° is a straight angle. So, 180°-110°= 70°.
The missing angle is 110°, I just solved for the remaining angle to help you figure it out more easily.

Answer:
[tex]x = 0[/tex]
Step-by-step explanation:
Write the number in exponential form with the base of 2:
[tex] {2}^{x - 3} = {2}^{ - 3} [/tex]
Since the bases are the same, set the exponents equals.
[tex]x - 3 = - 3[/tex]
Cancel equal terms on both sides of the equation:
[tex]x = 0[/tex]
[tex]2 {}^{x - 3} = \frac{1}{8} [/tex]
To Find value of 'x'
Solution[tex]2 {}^{x - 3} = \frac{1}{8} \\ \\ \implies2 {}^{x - 3} = 2 {}^{ - 3} \\ \\ \\ Since \: Bases \: Are \\ Equal \: We \: Need \\ To \: Evaluate \\ The \: Powers \\ \\ \implies \: x - 3 = - 3 \\ \\ \implies x = - 3 + 3 \\ \\ \implies \: x = 0[/tex]

Answer:
Each pencil was 3$
Step-by-step explanation:
the total amount spent is $29 and a magazine only cost $5 and she bought it pencils which brought the total to $29 the question is how much was each pencil.
The amount she spent on pencil is the total amount - $5 which is $29 - $5 which is $24 and we are told that she bought a total number of 8 pencils. the cost of each pencil will be 24/8 which is $3
What is the area of the shaded Region? (Answer to the Nearest Tenth)
Shaded area = Circle area - Rectangle area
Shaded area = 3.14 × (4)^2 - 5 × 6
Shaded area = 3.14 × 16 - 30
Shaded area = 50.24 - 30
Shaded area = 20.24
Shaded area = 20.2

The probability that the Austin orphaned pet is a dog is 32.34%.
The probability that the Austin orphaned dog is a Chihuahua is 29.38%.
What are the probabilities?Probability determines the chances that an event would happen in a random event. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that an orphaned pet in an animal shelter in Austin is a dog = total number of dogs in Austin / total number of pets
(2.76 + 2.86 + 3.44 + 2.65) / (2.76 + 2.86 + 3.44 + 2.65 + 24.50) =

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the way. Which decimal number shows the portion of the distance Sandy skips?
Answer:
0.2
Step-by-step explanation:
Convert the walking to percent
[tex]\frac{1}{2} \times 100 = 50[/tex]
Add both skateboarding and walking
[tex]30\% + 50\%\\\\= 30 + 50\\\\= 80[/tex]
Now, subtract that from a whole percent
[tex]100 - 80 = 20\\\\20\%[/tex]
Convert it to a decimal
[tex]20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2[/tex]
Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.
To make chocolate ice cream, you need about 3/8 pound of chocolate. How many pounds of chocolate will you need to make 4 batches of ice cream?
Answer:
1.5 pounds. it's simply 3/8 times 4
Answer:
1.5 pounds of chocolate
Step-by-step explanation:
A single batch of ice cream takes [tex]\frac{3}{8}[/tex] of a pound of chocolate. For every added batch, we add another [tex]\frac{3}{8}[/tex] pound, or multiply [tex]\frac{3}{8}[/tex] by the number of batches.
In this case, we are making 4 batches, so we need to multiply [tex]\frac{3}{8}[/tex] by 4.
[tex]4\cdot \frac{3}{8}[/tex]
[tex]\frac{4}{1}\cdot \frac{3}{8} =\frac{3}{2}[/tex]
[tex]\frac{3}{2}=1.5[/tex]
We need 1.5 pounds of chocolate to make 4 batches of ice cream.
Good luck ^^
How do I find the values of x & y without using the Pythagorean theorem?
It’s okay if you use it to give me the answer however, I don’t understand how you wouldn’t use it.

Answer:
23) x=20; y=10√3
24) x=4√2; y=8
25) x=12; y=3+6√3
Step-by-step explanation:
Recognize that all of the triangles involved here are one of the two "special" triangles. By previous use of the Pythagorean theorem, or your familiarity with the trig functions of the "special" angles 30°, 45°, 60°, you know the following side ratios:
45°-45°-90° triangle: 1 : 1 : √2
30°-60°-90° triangle: 1 : √3 : 2
Using these ratios, you can solve these figures "by inspection."
__
23) x = 2((10√2)/√2) = 20
y = √3((10√2)/√2) = 10√3
__
24) x = 4√2
y = (4√2)√2 = 8
__
25) x = 6·2 = 12
y = 3 +6√3 . . . . . 3 units more than the longer leg of the 6 : 6√3 : 12 triangle

Answer:

Step-by-step explanation:
How many different triangles can you make if you are
given these three lengths for sides?
17 cm
13cm
23cm
Answer:
1 triangle can be formed
We are given three side lengths, which are 17cm, 23cm, and 13cm. So, we can form the triangle when;
17 + 23 > 13
17 + 13 > 23
23 + 13 > 17
Since the above conditions are met, then we can form one triangle.
Now, each next triangle with the same sides lengths will be congruent to the first triangle by SSS postulate.
SSS postulate states that: If the three sides of a triangle are congruent to the three sides of another triangle, then the two triangles are congruent.
Thus, only 1 triangle can be formed.

29 degrees?
Answer:
151
Step-by-step explanation:
180 - 29
Answer:
B) 61
Step-by-step explanation:
When angles are complementary, that just means they add up to 90 so:
90 - 29 = 61
A semicircle with diameter 8 inches is connected to a triangle with a base length of 8 inches. The height of the triangle is 3 inches. What is the area of the composite figure? (8π + 6) in.2 (8π + 12) in.2 (8π + 18) in.2 (8π + 24) in.2
Answer:
B or (8π + 12) in.2
Step-by-step explanation:
The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].
How to estimate the area of the composite figure?The composite figure is made up of a semicircle and an isosceles triangle.
The area of a semicircle = (1/2)π[tex]r^{2}[/tex]
radius = 4 inch
When we substitute, the area of the semicircle is
= (1/2)π[tex]\times[/tex]16
= 8π [tex]$inch^{2}[/tex]
Area of the isosceles triangle = (1/2)bh
= (1/2)(4+4)[tex]\times[/tex]3
= 12 [tex]inch^{2}[/tex]
We add the two areas to acquire the area of the composite figure to be: (8π + 12) [tex]inch^{2}[/tex]
The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].
Therefore, the correct answer is option b. (8π + 12) in.2

The frequency for A is given as 20, this means A was spun 20 out of 75 spins.
20/75 = 0.2666 which rounds to 0.27
The answer is 0.27
We will see that the experimental probability is P = 0.27, so the correct option is c.
What is the experimental probability of spinning an "A" ?The experimental probability of the outcome A is equal to the quotient between the number of times that the outcome was A and the total number of times that the experiment was performed.
Here we know that the experiment was performed 75 times, and 20 of these 75 times, the outcome was A, then the experimental probability is:
P = 20/75 = 0.27
