Step-by-step explanation:
sin theta = opp / hyp
sin theta × hyp = opp
sin60 × 30 = opp
.866 × 30 = opp
25.98° = opp
*Theta is the 0 with a line through it
In the right ∆ABC, BL is an angle bisector. If LB = 1.2 in and LC = 0.6 in. Find:
- The distance from L to AB.
- m∠ABC
Answer:
Distance of L from AB = 0.6 in.
m∠ABC = 60°
Step-by-step explanation:
Given:
LB = 1.2 in
LC = 0.6 in
We have to find the distance of point L to AB or length of LD.
From right triangle ΔBCL,
Sin(∠LBC) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{LC}{LB}[/tex]
= [tex]\frac{0.6}{1.2}[/tex]
= [tex]\frac{1}{2}[/tex]
m∠LBC = 30° [Since ∠LBC is an acute angle]
Since, ∠LBC ≅ ∠LBA
m∠LBA = 30°
Now from right triangle ΔLDC,
sin(∠LBA) = [tex]\frac{LD}{BL}[/tex]
sin(30)° = [tex]\frac{LD}{1.2}[/tex]
[tex]\frac{1}{2}=\frac{LD}{1.2}[/tex]
LD = 0.6
Therefore, Distance of point L from AB is 0.6 in.
m∠ABC = m∠ABL + m∠LBC
= 30° + 30°
= 60°
7. Estimote the following percentages of 60.
10% =
25% =
50% =
20% =
Answer:
10% of 60 = 6
25% of 60 = 15
50% of 60 = 30
20% of 60 = 12
Step-by-step explanation:
Answer:
10% = 6
25% = 15
50% = 30
20% = 12
Step-by-step explanation:
10 % just drop the 0 from 60. 1/10 of 60 is 6
25% is 1/4. Divide: 60/4 =15
50% is half. Divide 60/2 = 30
20% is 1/5 Divide 60/5 =12

Henry runs up 10.5 flights of stairs. To represent an additive inverse, Henry will have to run down flights of stairs
Answer:
The additive inverse would be -10.5
Henry runs up 10.5 flights of stairs. Then the additive inverse represents running down flights of stairs will be - 10.5.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The reverse number is a number's complementary inverse. When a number is multiplied by its additive inverse, the result is zero.
Henry runs up 10.5 flights of stairs. Then the additive inverse represents running down flights of stairs will be - 10.5.

Write a linear function f with f(5)=7 and F(-2)=0.
Answer:
f(x)=x+2
Step-by-step explanation:
Slope= (7-0)/(5-(-2)) = 7/7 = 1
Y-intercept= 2
substitute the slope, 1, for m and the y-intercept, 2, for b to get:
f(x)=x+2
hope this helps!
The linear function f with f(5)=7 and F(-2)=0 is f(x) = x + 2
f(5) = 7
This means when x = 5 , y = 7
(5, 7)
f(-2) = 0
(-2, 0)
This implies when x = -2 , y = 0
Using the linear function formula,
y = mx + b
where
m = slope
b = y-intercept
Therefore, the function can be represented as follows:
m = 0 - 7 / -2 - 5 = -7 / -7 = 1
Therefore,
y = x + b
0 = -2 + b
b = 2
The function in relation to x can be represented as follows:
f(x) = x + 2

Mary had $60 and spent .75 of it for a coat. She then bought a skirt with 50%
of the money that she had left. How much money did she have left after buying
the coat and skirt?
The correct answer is She have left $7.5 after buying the coat and skirt.
Step-by-step explanation
This question is incomplete, the complete question is:
Mary had $60 and spent 0.75 o 3/4 of it on a coat. She then bought a skirt with 50% of the money that she had left. How much money did she have left after buying the coat and skirt?
The answer is $7.50
Explanation:
To know how much money Mary has left after buying the coat we have to multiply $60 by 0.75 as this would help us know the price of the coat.
60 x 0.75 = 45 (price of the coat)
Then we have to subtract 45 from 60 to know how much money she have left after buying the coat.
60 -45 = 15 (Money left)
Then she bought a skirt with 50% of the money that she had left. To know how much money costs the skirt we have to multiply 15 by 0.50. The result of this operation is $7.5, and finally, we have to subtract again $7.5 that she spent on her skirt from $15 and the final result is $7.5

Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third mile marker, she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?
Given:
Rita covered 1 mile in 15 minutes.
She covered 3 miles in 30 minutes.
To find:
The rate at which she is riding.
Solution:
Let y be the number of miles covered in x minutes.
Rita covered 1 mile in 15 minutes. So, the point is (15,1).
She covered 3 miles in 30 minutes. So, the point is (30,3).
Slope of the line:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-1}{30-15}[/tex]
[tex]m=\dfrac{2}{15}[/tex]
Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.

Step-by-step explanation:
Here, P = $3000, N = 1.5 years, R = 10%
[tex]SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\ [/tex]

Solve using fraction strips or common denominators:
1/2 + 3/10=
Answer:
4/5 (or 8/10)
Step-by-step explanation:
the least common denominator of 2 and 10 is 10, so you have to multiply the first fraction (1/2) by 5/5 so that the denominator of that fraction will become 10. Since 3/10 already has 10 as the denominator, you leave it. By adding 5/10 and 3/10 together you'll get 8/10.
If the question asks to simplify your answer, divide the numerator and denominator of 8/10 to get 4/5
