Answer:
A
Step-by-step explanation:
in a right triangle, the longest side (across from the right angle) is the hypotenuse (denoted as 'c')
the legs are denoted as 'a' and 'b'
the Pythagorean Theorem allows you to find the missing side using this formula:
a² + b² = c²

The distance Jane jogs in 20 minutes is 8 miles. At this rate, how many miles will he run in 60 minutes?
Answer: the answer is 24 miles
Step-by-step explanation:
Answer:
24 miles
Step-by-step explanation:
the ratio is 20:8
If we wanna find the ratio for 60 mins, you have to multiply both sides by three.
Then, we get 20/8 = 60/24
So, Jane jogged 24 miles in sixty minutes

Find the value of x in the triangle shown below
Answer:
x = 55
Step-by-step explanation:
Since 2 sides of the triangle are congruent, both 5, then the triangle is isosceles and the 2 base angles are congruent, both x , then
x + x + 70 = 180 ← sum of 3 angles = 180°
2x + 70 = 180 ( subtract 70 from both sides )
2x = 110 ( divide both sides by 2 )
x = 55
Answer:
55.52
Step-by-step explanation:
By sine rule:
[tex] \frac{ \sin x \degree}{5} = \frac{ \sin 70 \degree}{5.7} \\ \\ \sin x \degree = \frac{ 5 \: \sin 70 \degree}{5.7} \\ \\ \sin x \degree = \frac{ 5 \: \sin 70 \degree}{5.7} \\ \\ x \degree = {sin}^{ - 1} ( \frac{ 5 \: \sin 70 \degree}{5.7}) \\ \\ x \degree = 55.516753493 \degree\\ \\ x = 55.52[/tex]

Behind my math class help pls
Answer:
Please check the explanation.
Step-by-step explanation:
Part a)
Given that the two parallel lines are crossed by a transversal line.
Given that
m∠2 = 2x + 54 and m∠6 = 6x - 11
Angle ∠2 and ∠6 are corresponding angles.
Corresponding angles are congruent.
Thus,
m∠2 = m∠6
2x + 54 = 6x - 11
flipe the equation
6x - 11 = 2x + 54
subtract 2x from both sides
6x - 2x - 11 = 2x - 2x + 54
4x - 11 = 54
adding 11 to both sides
4x - 11 + 11 = 54 + 11
4x = 65
dvide both sides by 4
4x/4 = 65/4
x = 16.2500 (round to 4 decimal places)
Part b)
We have already determined
x = 16.2500
Given
m∠2 = 2x + 54
substitute x = 16.2500 in the euation
= 2(16.2500) + 54
= 86.5°
As angle ∠2 and angle ∠1 lie on a straight line. Hence, the sum of their angles must be 180°.
i.e.
m∠1 + m∠2 = 180°
substituting m∠2 = 86.5° in the equation
m∠1 + 86.5° = 180°
subtracting 86.5° from both sides
m∠1 + 86.5° - 86.5° = 180° - 86.5°
m∠1 = 93.5°
Therefore, the measure of angle m∠1 is:
m∠1 = 93.5°what is 3x + 7.9 = 9.1

Consider the following.
a number added to the difference between triple the number and thirteen
Answer:
Use x for your variable. Do not simplify
Step-by-step explanation:
Answer: Soooo----- x+(3x-13)
Step-by-step explanation:
So in this case i used x as number. Since we're not solving for anything this is just an expression. so the difference between triple the number so 3x and thirteen so (3x-13) and (a number) added so x+(3x-13) or number added to the difference between triple the number and thirteen
1. You need at least 3 pounds of fruit to make muffins. Blueberries cost
$4 per pound, strawberries cost $3 per pound and you can spend at
most $21 on fruit. (Create a system of inequalities)
Answer:
Step-by-step explanation:
b and s are the pounds of blueberries and strawberries, respectively.
b+s ≥ 3
4b + 3s ≤ 21
The system of inequalities can be represented as x+y≥3 and 3x+4y≤21.
What is inequality?Inequality shows relation between two expression which are not equal to each others.
Given that,
Cost of blueberries = $4 per pound
and cost of strawberries = $3 per pound
Let strawberries are x pound and blueberries are y pound, according to condition there should at least 3 pounds of muffins,
Therefore, x+y≥3
And maximum amount is $21
Therefore, 3x+4y≤21
The inequalities are x+y≥3 and 3x+4y≤21.

Read the passage and answer the question that follows.
Teachers should really think about the amount of math homework they assign to their students. All types of learners hate homework. If a student already knows how to work the math, why do they need to practice it over and over? And, students who don’t “get it” in class end up practicing incorrectly over and over, leading to an extreme dislike for school. I think requiring just a few practice problems is more appropriate for students.

4 of them were blue 1/6 of them were grape 1/4 of them were watermelon 1/3 of them were cherry 1/12 of them were sour apple how many candies were in her bag
Answer:
The girl had 24 candies in her bag.
Step-by-step explanation:
Since, regarding the girl's candies, 4 of them were blue, 1/6 of them were grape, 1/4 of them were watermelon, 1/3 of them were cherry and 1/12 of them were sour apple, to determine how many candies were in her bag, the following mathematical calculation should be performed:
1/6 + 1/4 + 1/3 + 1/12 = X
2/12 + 3/12 + 4/12 + 1/12 = X
10/12 = X
12/12 - 10/12 = 2/12
2/12 = 4
1/12 = 2
2 x 12 = 24
Thus, the girl had 24 candies in her bag.

The aspect ratio, the ratio of the width to the height, of various computer monitors is listed in the table below.
Answer: Monitor C is the different one.
Step-by-step explanation:
The aspect ratio is the relationship between width and height.
So we only need to see the quotients between width and height for each monitor and see which quotient is different.
Monitor A:
Quotient = 1152/864 = 1.333....
Monitor B:
Quotient = 800/600 = 1.333...
Monitor C:
Quotient = 1920/1080 = 1.777...
Monitor D:
Quotient = 1600/1200 = 1.333...
We can see that the one with a different aspect ratio is monitor C.
