a
the same watch for $60 and offers a 20% discount. From which store
should you buy, and why?

O Store B, $4.00 cheaper
O Store B, $9.50 cheaper
O Store A, $0.50 cheaper
O Store A, $9.50 cheaper

Answers

Answer 1

Answer:

  (c)  Store A, $0.50 cheaper

Step-by-step explanation:

When a price is discounted by a rate d, the multiplier of the price is (1 -d).

Store A

The discounted price is $50 × (1 -0.05) = $50×0.95 = $47.50

__

Store B

The discounted price is $60 × (1 -0.20) = $60×0.80 = $48.00

__

The price at Store A is less by ...

  $48.00 -47.50 = $0.50

Answer 2
SOLUTION :-

shop A and B we have :-

shop = 5 ÷ 100 × 50 = 2.5

shop = 20 - 60 × 100 = 12

shop = $50 - 2.5 = $ 47.5

Shop = $60 - 12 = $48

then, we have to minus $48 .00 with $ 47.50 we get :-

= $48 .00 - $ 47.50 = $0.50

Store A, $0.50 cheaper

Answers

Answer:

[tex]y= \frac{5}{9}x - 2[/tex]

Step-by-step explanation:

Let's write the equation in the slope-intercept form! In the slope-intercept form, y= mx +c, m is the slope and c is the y-intercept.

[tex]\textcolor{blueviolet}{\text{\textcircled{1} Find \: the \: slope}}[/tex]

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

Slope

[tex] = \frac{ - 2 - ( - 7)}{0 - ( - 9)} [/tex]

[tex] = \frac{ - 2 + 7}{0 + 9} [/tex]

[tex] = \frac{5}{9} [/tex]

[tex]\textcolor{blueviolet}{\text{\textcircled{2} Substitute \: value \: of \: slope}}[/tex]

[tex]y = \frac{5}{9} x + c[/tex]

[tex]\textcolor{blueviolet}{\text{\textcircled{3} Substitute \: a \: pair \: of \: coordinates}}[/tex]

When x= 0, y= -2,

[tex] - 2 = \frac{5}{9} (0) + c[/tex]

c= -2

[tex]\textcolor{blueviolet}{\text{\textcircled{4} Substitute \: value \: of \: c}}[/tex]

If a chemical costs $3.54 for 20 ounces, what is the cost of 25 gallons of the chemical?

Answers

there are 128 fluid ounces in 1 gallon, that means that 25 gallons is 25 * 128 = 3200 ounces.

so if we know that for 20 ounces is 3.54, how much will it be for 3200 ounces?

[tex]\begin{array}{ccll} \$ & oz\\ \cline{1-2} 3.54 & 20\\ x& 3200 \end{array} \implies \cfrac{3.54}{x}=\cfrac{20}{3200}\implies \cfrac{3.54}{x}=\cfrac{1}{160}\implies 566.4=x[/tex]

Oxygenated blood is pumped to the body by the

m<a = 3x+11 and m<b = 17x-91. The angles are supplementary. Find the value of x.​

Answers

Answer:

x = 13

Step-by-step explanation:

Supplementary means 180 degrees.

Since we are finding the supplement, we are going to add both angles together and solve for x.

3x + 11 + 17x - 91 = 180

~Combine like terms

20x - 80 = 180

~Add 80 to both sides

20x = 260

~Divide 20 to both sides

x = 13

Best of Luck!

Answer:

Since the measure of both angles are supplementary, its easy to form the equation.

3x+11+17x-91 = 180

20x-80 = 180

20x = 100

x = 5

m<a = 3x+11

= 3(5)+11

= 15+11

= 26

m<b = 17x-91

= 17(5)-91

= 85-91

Answer: B. 8 3/4

Step-by-step explanation:

The amount of sand he needs would be equal to the volume of the sand box.

Since the sandbox is a rectangular prism, the volume if the length*width*height/depth.

We can plug in the values given.

Volume = 3.5 feet*5 feet * 0.5 feet

Volume = 8.75 feet^3 = 8 3/4 feet^3

Answer:

B. 8 3/4

Step-by-step explanation:

How do we find the volume of a rectangular prism?

  ❖ The volume of a rectangular prism can be found by using the formula

       length × width × height. We're given all the dimensions, so now we can

       solve for the volume

Solving

[tex]3.5*5*0.5[/tex] [tex]17.5 * 0.5[/tex] [tex]8.75[/tex] [tex]8.75 = 8\frac{3}{4}[/tex]

if a shopkeeper sold a watch for Rs 640 at a loss of 20%,find the cost price of the watch​

Answers

Answer:

Rs 800

Step-by-step explanation:

Selling Price =Rs640

Loss=20%

Let the cost price of the watch be Rs x.

SP=CP-20%of CP

or, 640=x-x/5

or, 640=4x/5

or, 4x=640*5

or,x=3200/4

Therefore, x=Rs 800. The cost price of the watch is Rs 800.

A group of friends are having a 400 m race julze can run 25 meters in 4 seconds alex can run 60 meters in 10 seconds jaheim can run 6.5 meters Yuseph can run 100 meters in 15 seconds if each of them could keep their constant speed who would win the race explain your answer.

Answers

Answer:

Yuseph would win the race because he has the highest speed and will run 400m in 60 seconds

Step-by-step explanation:

Race = 400m

julze can run 25 meters in 4 seconds

= 400m / 25m × 4 seconds

= 16 × 4

= 64 seconds

alex can run 60 meters in 10 seconds

= 400m / 60m × 10 seconds

= 6.67 × 10

= 66.7 seconds

Yuseph can run 100 meters in 15 seconds

= 400/100 × 15 seconds

= 4 × 15

= 60 seconds

jaheim can run 6.5 meters

Yuseph would win the race because he has the highest speed and will run 400m in 60 seconds
