Answer:first fine the perimeter 42cm then do the lenth then width and u get the answer
Step-by-step explanation:
or find it on google
Answer:
length= 14cm and width= 7cm
Step-by-step explanation:
The ratio of the length to width is 2:1 so [tex]\frac{length (l)}{width(b)} =\frac{2}{1}[/tex] The perimeter is the sum of 2 length sides and 2 width sides so [tex]perimeter=length+length+width+width=2length+2width[/tex] Now from the ratio we know [tex]\frac{length (l)}{width(b)} =2[/tex] so [tex]length=2width[/tex] So put that into the perimeter equation[tex]perimeter=2(2width)+2width[/tex] so the perimeter is 42cm[tex]42cm=2(2width)+2width\\42cm=4width+2width\\42cm=6width\\width=7cm[/tex] Since length is twice the width, length is 14 cmUne gratification est partagée en quatre employés - le premier reçois 150euro - le seconde reçois 7/20 de la gratification -le troisieme reçois 5/28 de la gratification - le quatrième reçois le 9/35 de la gratification a) Quel est le montant de la gratification ? b) Quel est la part reçu par le premier ? c) Quel est le montant reçu par chaque employés
Explication étape par étape:
Soit la gratitude totale x
Montant reçu par le premier employé = 150 euros
Si le second reçoit 7/20 de la gratification, alors;
Deuxième reçoit = 7/20 × x
Si le troisième reçoit 5/28 de la gratification, alors
Le troisième reçoit 5/28 × x -
Si le quatrième reçoit le 9/35 de la gratification, alors;
Le quatrième reçoit 9/35 × x
Il faut ensuite calculer le pourboire total x.
Résumer tout le montant reçu
7x / 20 + 5x / 28 + 9x / 35 +150 = x
0,35x + 0,179x + 0,257x + 150 = x
0,786x + 150
x-0,786x = 150
0,214x = 150
x = 150 / 0,214
x = 700,9 euros
2) Pour obtenir le partage collecté par le premier, nous utiliserons l'expression
X × 700,9 = 150
x = 150 / 700,9
x ≈ 15/70
x≈ 3/14
D'où le premier a recueilli environ 3/14 de la gratification totale.
2) seconde collectée 0,35x
= 0,35 × 700
≈245 euros
Le troisième a recueilli 5/28 de x
Le troisième a collecté 5/28 × 700
= 3500/28
= 125 euros
Le quatrième a recueilli 9/35 de x
= 9/35 × 700
= 6300/35
≈ 180 euros

Find the slope (-3, 7) and (0, - 2)
Can show steps too please I’ll mark u brainliest
Answer:
The answer is -3
Step-by-step explanation:
Slope means the rate of change of a line which is the letter m. Whenever you need to find slope remember this: m= y2-y1 over x2-x1.
(x1,y1)= (-3,7), ( x2, y2) = (0,-2) so the slope is -3.

Jaythen finds a shirt on sale for 10% off at a store. The original price was $20. Jaythen must also pay 8.5% sales tax. How much is the shirt before taxes? *
How much does Jaythen pay total for his shirt after taxes? *
Answer:
the shirt before taxes is $18. the shirt after taxes is 19.53
Step-by-step explanation:
you multiply 20x.10 and you'll get 2. so you subtract 2 from 20, that's $18.
to get taxes, you multpliply 18x.085 and you get $1.53.
you then add $1.53 to 18 and you get your total price of $19.53
Answer:
Before taxes, the shirt was $18. After taxes. the shirt is $19.53

.Ahmed is making pancakes, his recipe uses 150g of flour for 8 pancakes. How much flour will he need to make 12 pancakes? Remember to give units in your answer.
Answer:
Ahmed needs 225g of flour to make 12 pancakes.
Step-by-step explanation:
With the information provided, you know that the recipe uses 150g of flour for 8 pancakes and you can use a rule of three to find the amount of flour needed to make 12 pancakes:
150g → 8 pancakes
x ← 12 pancakes
x=(150*12)/8= 225g
According to this, the answer is that Ahmed needs 225g of flour to make 12 pancakes.
In a system of two linear equations, the lines represented by each equation have the same slope and different y-intercepts. Which would be the total number of solutions to the system of equations?
Answer:
There will be no common solution
Step-by-step explanation:
Given that the lines that represent the equations in the system of the two linear equations have equal slope but that their y-intercept are different, we have;
The two lines are parallel to each other
The two lines are different lines, given that they have different y-intercept
By definition of parallel lines, we have that the two lines representing the two equations will never meet, and therefore, both equations do not have a common solution which is a value that satisfies both equations
Therefore, the two equations in the linear system of equations, do not have a common solution
When most American’s throw away their laundry detergent bottle it has about 1/2 of an ounce of detergent left in it. Dexter’s equation, y= -1.6x+50, and Mya’s equation, y = 50(.75)x. represent how much detergent is left in their bottles after x washes. Who will throw away their laundry detergent bottle first?
Answer:
Mya’s equation
Step-by-step explanation:
Given that:
Detergent left in bottle after a certain number of washes x
Dexter’s equation,
y= -1.6x+50
Mya’s equation,
y = 50(.75)x
y = Detergent left in bottle.
Given that amount of Detergent left is about 1/2 ounces = y
For Dexter’s equation,
y= -1.6x+50
0.5 = 1.6x + 50
0.5 - 50 = 1.6x
-45.5 = 1.6x
x = 28.4375
For Mya’s equation :
y = 50(0.75)x
0.5 = 37.5x
0.5 / 37.5 = x
0.0133333 = x
Hence, Mya’s equation

Neveah goes out to dinner at a restaurant. The bill for dinner is $57.25, and Neveah gives the server a 20% tip. What is the total cost for dinner?
Need answer please :(
Answer:
11.45 + 57.25
Step-by-step explanation:
$68.70 is the correct answer because the question asks WHAT IS THE TOTAL COST FOR THE DINNER
The total cost he paid is $68.7
What is percentage?Percentage, a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part;
Given:
Bill for dinner is $57.25
20% tip was given
So, 20% on 57.25 is
=0.20 * 57.25
=11.45
Hence, total he paid = 57.25 +11.45 = 68.7

Austin and Dylan rode their bicycles. Austin's average speed is represented by the equation d = 20t, where d is the total distance traveled in t hours. The graph below represents Dylan's average speed while riding his bicycle.
Who had the fastest average speed and by how much?
Answer:
Austin has the better average speed by 5 mph
Step-by-step explanation:
The slope of Dylan’s graph will his average speed
Let’s select two points on the graph to use
The slope can be calculated as;
m = (y2-y1)/(x2-x1)
m = (90-30)/(6-2)
m = 60/4
m = 15
So the equation for Dylan would be
d = 15t
This shows that Austin has a faster average speed by 5 mph

Answer:
$732.5
Step-by-step explanation:
Mae Ling earns a weekly salary of $365 which means salary per week is $365
Then plus a 7.5% commission on sales at a gift shop if she sold $4,900 worth of merchandise, which means additional
(0.075×4900)=367.5
The total she make will be
367.5+365
=$732.5
Therefore,she will make $732.5 in a work week if she sold $4,900 worth of merchandise
Joaquín compró una docena y media de factura la docena son parte de grasa dos tercios tiene dulce de leche y el resto son medialunas cuántas son de grasa Cuánto tiene dulce de leche Cuántas medialunas compró
Answer:
2 facturas de grasa.
12 facturas con dulce de leche
4 medialunas
Step-by-step explanation:
Una docena contiene 12 facturas y media docena contiene 6 facturas. Entonces Joaquin compro un total de 18 facturas (12+6). Si la novena parte (1/9) de las facturas son de grasa entonces solo multiplicamos esta fraccion por la totalidad de las facturas.
18 * (1/9) = 2 facturas de grasa.
La cantidad de facturas que tienen dulce de leche son dos tercios (2/3) de la totalidad. Entonces multiplicamos esta fracion for la totalidad.
18 * (2/3) = 12 facturas con dulce de leche
Por final, la cantidad de media lunas es el resto de las facturas, entonces descontamos las facturas de grasa y con dulce de leche de la totalidad para saber cuantas facturas son medialunas
18 - 2 - 12 = 4 medialunas
