Answer:
He sold 10 hangers and 10 neclesses
Step-by-step explanation:
Given data
Let the number of door hanger be x
and the number of neckless be y
so
x+y= 20---------1
also,
2.25x+3.75y= 60---------2
Solve 1 and 2 together
From 1
x= 20-y
put this in place of x in 2
2.25(20-y)+3.75y= 60
45-2.25y+3.75y= 60
1.5y= 60-45
1.5y= 15
y= 15/1.5
y= 10
Put y= 10 in 1
x+10= 20
x= 20-10
x= 10
Where is f of x equals the quotient of x plus 5 and the quantity x squared plus 9 times x plus 20 discontinuous?
A. -4
B. 5
C. f(x) is continuous everywhere
D. -5, -4

If P is the incenter of triangle JKL, find PJ.
Answer:
PJ = 41.34
Step-by-step explanation:
P is incenter, three angles bisector meet
∠MJP ≅ ∠OJP
PM = PN = PO = 22 (radius: property of incenter)
∠JPM = 90 - ∠MJP = 90 - OJP = ∠JPO
ΔJPM ≅ ΔJPO (ASA) or (SAS)
LM = JO
2x + 3 = 5x - 45
3x = 48
x = 16
JM = 35
PJ = √35²+22² = √1709 = 41.34
The value of PJ in triangle KJL is 41.32 units.
What is incenter?The point formed at the intersection of the three angle bisectors of a triangle; also the centre of the incircle.
Given that, P is incenter of the triangle KJL,
Considering the triangles ΔMJP and ΔOJP
PM = PO (property of incenter)
∠ JMP ≅ ∠ JOP
JP is common segment.
ΔJPM ≅ ΔJPO (by SAS rule)
JM = JO (CPCTC)
2x + 3 = 5x - 45
3x = 48
x = 16
JM = 35
Using the Pythagoras theorem,
PJ² = PM²+JM²
PJ = √35²+22² = √1709 = 41.34
Hence, The value of PJ in triangle KJL is 41.32 units.

Maggie is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 10 inches × 13 1 2 inches. She needs to cut another rectangle that is 10 1 3 inches by 10 1 2 inches. How many total square inches of construction paper does Maggie need for her project?
Answer:
243.5 in²
Step-by-step explanation:
Given :
Dimension of rectangule 1 :
10 inches * 13 1/2 inches
Area = (10 * 27/2) inch² = 135 in²
Dimension of rectangle 2 :
10 1/3 inch * 10 1/2 inch
Area = (31/3 * 21/2) in² = 108.5 in²
Tot square inch of construction paper needed /
(135 in² + 108.5 in²) = 243.5 in²

Trey pourd 5 1/2 cups of birdseed into an empty bird feeder. The bird feeder is now 3/4 full. How much more for it to be full.
Answer:
1 and 1/3 Cups
Step-by-step explanation:
3/4 of the birdfeed is filled by 5.5 cups
3/4 x= 5.5
solve for x my multiplying by 4/3 to see how much space is left in the feeder
=1 and 1/3 space left
The cup needs 1 5/6 cups more birdseed to fill the bird feeder completely.
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
If the bird feeder is 3/4 full after Trey poured 5 1/2 cups of birdseed, then we can find the total capacity of the bird feeder by dividing the 5 1/2 cups by 3/4:
5 1/2 / 3/4 = 22/4 / 3/4 = 22/4 x 4/3 = 88/12 = 22/3
So the bird feeder can hold 22/3 cups of birdseed when it's full.
Since the bird feeder is already 3/4 full, we need to fill the remaining 1/4 of the bird feeder
On simplifying the equation , we get
1/4 x 22/3 = 22/12 = 1 10/12 cups
Hence , we need 1 10/12 cups or 1 5/6 cups more birdseed to fill the bird feeder completely

The ratio of pitchers to catchers at a baseball camp was 11:4. If there were 64 catchers, how many pitchers were at the camp?
Answer:
There were 176 pitchers at the camp.
Step-by-step explanation:
Given that,
The ratio of pitchers to catchers at a baseball camp was 11:4.
Let pitchers be 11x and catachers be 4x.
Total catchers = 64
4x = 64
x = 16
So,
Pitchers = 11x
= 11(16)
= 176
Hence, there were 176 pitchers at the camp.

Quadrilateral QRST has diagonals that are perpendicular but not congruent. Which type of quadrilateral could describe quadrilateral QRST?
Answer:
Rhombus
Step-by-step explanation:
This undoubtedly has to be a rhombus. When you look at other quadrilaterals for example and want to judge and or differentiate, we see that in the case of a square, the diagonals are equal to one another and they are not congruent. Same can be applied to that of a rectangle as well, it's diagonals aren't congruent, even if they appear perpendicular.
On the other hand, the diagonals of a rhombus is both perpendicular, and at the same time congruent. And thus, that's our answer
A teacher is planning a class trip to the aquarium. The aquarium requires 2 chaperones for every 15 students. The teacher plans accordingly and orders a total of 85 tickets. How many tickets are for chaperones, and how many are for students?
Answer:
75 student tickets and 10 chaperone tickets
Step-by-step explanation:
First find out how many groups there are total by dividing 85 by 1 group total of 17 (15 students 2 chaperones).
85 / 17 = 5
Since you now know there are five groups of 15 students and 2 chaperones all you have to do is multiply 5 time 15 students and 5 times 2 chaperones.
15 x 5 = 75 for students
5 x 2 = 10 for chaperones

What is the degree measure of ABC given that A=25 & C=135?
Answer:
m∠ABC = 110°
Step-by-step explanation:
By the property of exterior angle of a triangle,
"Exterior angle of a triangle is equal to the sum of two opposite interior angles"
m∠BAC + m∠ABC = 135°
25° + m∠ABC = 135°
m∠ABC = 135° - 25°
= 110°
Therefore, measure of angle ABC is 110°.

Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
now apply the above rules to the given triangle
where we are given the angle of 30° and the Adj side of 27
y is the Hyp of this triangle and x is the Opp side of this triangle, now plug in the given values as follows
so use CAH Cos(30) = 27 / Hyp
Hyp = 27 / Cos(30)
Hyp = 27 / ([tex]\sqrt{3}[/tex] / 2)
Hyp = 27 * 2 / [tex]\sqrt{3}[/tex]
Hyp = 54 / [tex]\sqrt{3}[/tex]
y = 54 / [tex]\sqrt{3}[/tex]
use SOH, since we know the exact value for the Hyp from above
Sin(30) = Opp / ( 54 / [tex]\sqrt{3}[/tex] )
Sin(30) * 54 / [tex]\sqrt{3}[/tex] = Opp
1/2 * 54 / [tex]\sqrt{3}[/tex] = Opp
27 / [tex]\sqrt{3}[/tex] = Opp
x = 27 / [tex]\sqrt{3}[/tex]
