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
AND find the measurement of
Answer:
[tex]\overline {LD}[/tex] = 0.6 inch
m∠ABC = 60°
Step-by-step explanation:
The given parameters are;
The given triangle ΔABC = A right triangle
The angle bisector of ∠CBA = BL
The length of BL = LB = 1.2 in.
The length of LC = 0.6 in.
We have;
[tex]\overline {LB}[/tex] ≅ [tex]\overline {LB}[/tex] reflexive property
∠ABC = ∠CBL + ∠DBL and ∠CBL ≅ ∠DBL definition of bisected angle
∠CBL = ∠DBL by definition of congruency
∠CLB + ∠CBL = ∠CLB + ∠DBL = 90°, opposite angles of a the right angle triangle are supplementary
∴ ∠CLB = ∠CLB by addition property of equality
ΔLDB ≅ ΔLBC are congruent by the Angle-Side-Angle rule of congruency
∴ [tex]\overline {LD}[/tex] ≅ [tex]\overline {LC}[/tex] Congruent Parts of Congruent Triangles are Congruent (CPCTC)
[tex]\overline {LD}[/tex] = [tex]\overline {LC}[/tex] = 0.6 in. by definition of congruency
[tex]\overline {LD}[/tex] = 0.6 in.
sin(m∠CBL) = Opposite side/(Hypotenuse side) = [tex]\overline {LC}[/tex]/[tex]\overline {LB}[/tex] = 0.6/1.6 = 1/2
m∠CBL = sin⁻¹(1/2) = 30°
m∠CBL = m∠DBL = 30°
m∠ABC = m∠CBL + m∠DBL = 30° + 30° = 60°
m∠ABC = 60°

An advertisement reads “All Books 28 Percent Off.” A best-selling novel is originally priced at $18.99. About how much money will Gio save if he buys the novel on sale?
$2
$6
$10
$14
Answer:
6 dollars i think
Step-by-step explanation:
Answer:
Gio will save about $6.
Step-by-step explanation:
You would convert 28% to a decimal which is 0.28 and then multiply 0.28 by $18.99 and you would get $5.3172 which is closest to $6 so it would be B. about $6

Jada earns twice as much money per hour as Diego. Diego earns twice as much money per hour as lin. Select all the graphs that could represent how much Jada, diego, and lin earn for different amounts of time worked.
Answer:
1 and 3Step-by-step explanation:
Let functions be
Jada = f(j)Diego = f(d)Lin = f(l)As per given ratios:
f(d) = 2f(l)f(j) = 2f(d) ⇒ f(j) = 4f(l)The smallest slope belongs to f(l), greater - f(d), the greatest - f(j)
Possible graphs reflecting the functions are graph 1 and graph 3

The next two term is 13 and 16 respectively.
Step-by-step explanation:
here,
a1 = -2
a2 = 1
a3 = 4
a4 = 7
a5 = 10
So, d = a2 - a1 = 1 - (-2) = 3
= a3 - a2 = 4 - 1 = 3
Here, Common difference is same everywhere and the value of d is 3
Then,
To find 6th term of this sequence
a6 = a5 + d
= 10 + 3
a6 = 13
To find 7th term of this sequence
a7 = a6 + d
= 13 + 3
a7 = 16
Thus, The next two term is 13 and 16 respectively.

It 's an isosceles triangle if you look carefully. 2 Sides of the triangle are equal which is denoted by those marks. The angles opposite to the equal sides are always equal, so: [tex]m\angle FST = 64^\circ[/tex]
By angle sum property, [tex]m\angle TFS = 180 - 2 * 64 = 180 - 128 = 52^\circ[/tex]
52 degrees is the answer: Option D :D
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]
FT = FS \: \: → \: \: angle \: \: T = angle \: \: S \\ [/tex]
Thus ;
[tex]angle \: \: S = 64°[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Sum of the interior angles of any triangle is 180° .
Thus ;
[tex]T + F + S = 180°[/tex]
[tex]64° + F + 64° = 180°[/tex]
[tex]F + 128° = 180°[/tex]
Subtract sides 128°
[tex]F + 128° - 128° = 180° - 128° \\ [/tex]
[tex]F = 52°[/tex]
So :
[tex]TFS = F = 52°[/tex]

4. Sasha sells t-shirts. Each day she earns a set amount, plus a
commission. Write a linear function fto determine Sasha's pay.
T-shirts 1 2 3 4 5
Total Pay 68 71 74 77 80
Answer:
The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65
Step-by-step explanation:
Let x be the number of t-shirts and y be the total pay
As we can clearly see in the table that there is a linear relationship between x and y
A linear function is given as:
[tex]y = mx+b[/tex]
Here m is the gradient of the function then
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Taking any two pairs of x and y
(1,68) and (2,71)
[tex]m = \frac{71-68}{2-1}\\m = 3[/tex]
Putting in equation
[tex]y = 3x+b[/tex]
Putting a pair (1,68) in the equation to find the value of b
[tex]68 = 3(1) + b\\68 = 3+b\\b = 68-3\\b = 65[/tex]
Putting the value of b
[tex]y = 3x+65[/tex]
Let p(x) be the linear function
Hence,
The linear function is: p(x) = 3x+65
Answer:
y=3x+65

Your making chocolate chip cookies. The recipe calls for 1/8 teaspoon salt to 1/4 teaspoon baking soda. How much salt is needed for one teaspoon of baking soda
Answer:
1/2 teaspoon salt
Step-by-step explanation:
We can make this into a ratio of salt:baking soda
1/8:1/4
now, how many 1/4 will we need to make 1?
If we multiply 1/4 by 4, we get one. So, we should do the same to 1/8!
1/8*2=4/8, or 1/2 teaspoon

A local hamburger shop sold a combined total of 555 hamburgers and cheeseburgers on Saturday. There were 55 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Saturday?
Answer:
There were 250 hamburgers sold on Saturday.
Step-by-step explanation:
∵ A local hamburger shop sold a combined total of 555 hamburgers
and cheeseburgers on Saturday
→ Assume that the shop sold x hamburgers
∵ The shop sold x hamburgers
∵ There were 55 more cheeseburgers sold than hamburgers
→ That means the number of cheeseburgers is greater than the
number of hamburger by 55
∴ The shop sold x + 55 cheeseburgers
∵ The shop sold 555 burgers
→ Add the two types of burgers and equate the sum by 555
∴ x + x + 55 = 555
∴ 2x + 55 = 555
→ Subtract 55 from both sides
∴ 2x + 55 - 55 = 555 - 55
∴ 2x = 500
→ Divide both sides by 2 to find x
∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{500}{2}[/tex]
∴ x = 250
∵ x represents the number of hamburgers
∴ There were 250 hamburgers sold on Saturday.

(x-7)(x-3)
find the 2 numbers that when multiplied make the last number or +21 and when combined make the middle number of -10. -7*-3 = 21 and -7+-3=10
Answer:
(x - 7)(x - 3)
Step-by-step explanation:
Given
x² - 10x + 21
Consider the factors of the constant term (+ 21) which sum to give the coefficient of the x- term (- 10)
The factors are - 7 and - 3 , since
- 7 × - 3 = + 21 and - 7 - 3 = - 10, thus
x² - 10x + 21 = (x - 7)(x - 3) ← in factored form
