Rita is selecting a sandwich at the deli. The deli has four types of meat, three types of cheese and two types of bread. A deluxe sandwich consists of exactly one meat type, two different types of cheese and one bread type. How many different deluxe sandwich combinations are possible
Answer:
24 possible dishes
Step-by-step explanation:
Given
Total
[tex]Meat = 4[/tex]
[tex]Cheese = 3[/tex]
[tex]Bread = 2[/tex]
Selection
[tex]Meat = 1[/tex]
[tex]Cheese =2[/tex]
[tex]Bread = 1[/tex]
Required
Determine the number of possible combo
Rita wants to select 1 of 4 meat types,
So, the number of selections is: [tex]^4C_1[/tex]
Rita wants to select 2 of 3 cheese types,
So, the number of selections is: [tex]^3C_2[/tex]
Rita wants to select 1 of 2 cheese types,
So, the number of selections is: [tex]^2C_1[/tex]
The total number of selections is:
[tex]Total = ^4C_1 * ^3C_2 * ^2C_1[/tex]
Using
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
We have:
[tex]Total = \frac{4!}{(4-1)!1!} * \frac{3!}{(3-2)!2!} * \frac{2!}{(2-1)!1!}[/tex]
[tex]Total = \frac{4!}{3!1!} * \frac{3!}{1!2!} * \frac{2!}{(1!1!}[/tex]
[tex]Total = \frac{4*3!}{3!*1} * \frac{3*2!}{1*2!} * \frac{2*1}{1*1}[/tex]
[tex]Total = 4* 3 * 2[/tex]
[tex]Total = 24[/tex]
Hence, there are 24 possible dishes

Jared is making accessories for the soccer team. He uses 819.36 inches of fabric on headbands for 45 players and 3 coaches. He also uses 433.80 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
Fabric used for each player = 26.71 inches (Approx)
Step-by-step explanation:
Given:
Fabric used for headbands = 819.36 inches
Fabric used for wristbands = 433.80 inches
Find:
Fabric used for each player
Computation:
Fabric used for each player headband = 819.36 / [45+3]
Fabric used for each player headband = 17.07 inches
Fabric used for each player wristbands = 433.80 / [45]
Fabric used for each player wristbands = 9.64 inches
Fabric used for each player = 17.07 + 9.64
Fabric used for each player = 26.71 inches (Approx)

Answer:
KY = 12PK = 12m∠YKZ = 90°m∠PZR = 67°AQ = 3m∠APQ = 45°m∠MNP = 90°PM = 6Step-by-step explanation:
The diagonals of a rhombus are perpendicular bisectors of each other.
__
1. KY is the long leg of right triangle KYR, whose hypotenuse is given as 13 and short leg as 5. If you do not recognize this as a 5-12-13 right triangle, you can find the longer leg using the Pythagorean theorem.
KY² +RK² = RY²
KY² = RY² -RK² = 169 -25 = 144
KY = √144 = 12
__
2. K is the midpoint of diagonal PY, so PK = KY = 12.
__
3. As we have said, the diagonals cross at right angles.
m∠YKZ = 90°
__
4. PZ is parallel to RY, so the alternate interior angles created by diagonal ZR are congruent.
m∠PZR = m∠YRZ = 67°
_____
5. We recognize that hypotenuse PQ of right triangle PQA is √2 times the side length AP. So, this is a "special right triangle" that is isosceles. The sides and hypotenuse have the ratios 1 : 1 : √2.
AQ = AP = 3
__
6. As in any isosceles right triangle, the acute angles are 45°.
m∠APQ = 45°
__
7. Each of the smaller acute angles is 45°. The diagonals bisect the corner angles, so each corner angle is 2×45° = 90°.
m∠MNP = 90°
__
8. A is the midpoint of PM, so PM is twice the length of AP.
PM = 2×AP = 6

Angel RTQ is a straight angle. What are m angle RQS and m angle TQS?
Answer:
Step-by-step explanation:
(21x+1)+(14x+4)=180
35x+5=180
35x=175
x=5
(21{5}+1)
105+1
Angle< RQS=106 degrees (14{5}+4)
Angle TQS=74
Angel RTQ is a straight angle, the measure of angle RQS and the measure of angle TQS is, 61° & 74°
What is an angle ?An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
Given that,
A line segment, RQT
And one ray, QS
∠TQS = (21x + 1)°
∠RQS = (14x + 4)°
it is known that,
Straight angle = 180°
∠TQS + ∠RQS = 180°
(21x + 1)° + (14x + 4)° = 180°
35x + 5 = 180°
35x = 175°
x = 5°
∠TQS = (21×5 + 1)° = 61°
∠RQS = (14×5+ 4)° = 74°
Hence, the measure of ∠TQS & ∠RQS are respectively 61° & 74°

Ann car can go 117 miles on 3 gallons of gas. During a drive last weekend, Ann used 8 gallons of gas. How far did she drive?
Answer:
Ann drove 312 miles in 8 gallons.
Step-by-step explanation:
Distance covered by Ann's car = 117 miles
Gallons of gas spent by Ann's car to cover 117 miles = 3 gallons
Unit rate = 117 miles / 3 gallons
= 39 miles per gallon
so Ann's car can go 39 miles in one gallon of gas.
Given that Ann used 8 gallons of gas.Therefore,
Distance covered by Ann's car in 8 gallons = 39 × 8
= 312 miles
Therefore, Ann drove 312 miles in 8 gallons.

Each morning Rin rides 1.5 miles to school and then rides home in the afternoon. Later in the evening, she rides to the
park and back home. Over the 5 school days, she rides a total of 25 miles. Which equation can be used to find the
distance she rides each evening?
Answer:
5( 1.5 + 1.5 + x ) = 25
Step-by-step explanation:
Given:
Rin 1.5 miles to school every morning and then rides home in the afternoon.Calculations:
The total distance covered by Rin is (1.5 + 1.5) miles. In the evening, Rin rides to the park and back home. Let, 'x' miles be the total distance covered by her while going to the park and coming back home every evening. The total distance that she rides everyday will be: 5( 1.5 + 1.5 + x ) = 25The tortoise and the hare are having a race. After the hare runs 16 miles the tortoise has only run 4 miles.

Multiply the whole numbers into the fractions:
[tex]-\frac{28}{9} -(-\frac{25}{3})[/tex]
Remove parentheses
[tex]-\frac{28}{9} + \frac{25}{3}[/tex]
Multiply the second fraction by [tex]\frac{3}{3}[/tex] to reach a common denominator

Add
[tex]\frac{47}{9}[/tex]
Simplify into a top-heavy fraction or a mixed fraction (whichever your homework wants)
[tex]\frac{47}{9}[/tex] or [tex]5\frac{2}{9}[/tex]
The simplified fraction is 47/9.
What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.We have -3 1/9 - (-8 1/3)
Simplifying the above expression
= -28/9 - (-25/3)
= -28/9 + 25/3
= -28/9 + 75/9
= 47/9
