Brady rented a car for two days at $25 a day plus
$0.15 per mile. If his total bill came to $102.50, how
many miles did Brady drive?

Answers

Answer:

He drove 350 miles.

Step-by-step explanation:

I need points.

Brady drove 16.67 miles extra.

What is division?

One type of operation in mathematics is division. We divide the expressions or numbers into the same number of components during this operation.

Given, Brady rented a car for two days at $25 a day plus $0.15 per mile.

His total bill is $102.50.

We divide the 102.50 by 25.

That means, 102.50 / 25

= 4 is quotient and 2.50 is remainder.

Now we divide 2.50 by 0.15

That means, 2.50 / 0.15

= 16.67 miles

Therefore, 16.67 miles, Brady drove.

Step-by-step explanation:

We can cross of A. because if A. were to be correct, nothing else would be correct.

Now we know it has to be B. or C. and D.

D. has to be one of them since you can't have B. and C.

To find out if it is either B. or C. we need to think into it more. So if we had the mean of 80%, that means we need to have some scores over 75%. That would be C. since it says 75% or greater.

Erin created a scale drawing for a garden that will be 10 ft by 5 ft. She plans to include a section in the garden for herbs, which will be 2 ft by 5 ft. On Erin’s scale drawing, the entire garden is 12 in. by 6 in. What are the dimensions of the herb garden on the scale drawing?

(GIVING BRAINLIEST) if you solve it

Answers

Answer:

The dimensions of the herb garden on the scale drawing are 2.4 by 6 inches

Step 1 (finding the scale factor):

12/10 (inches/feet) or 1.2 (inches/feet)

(1.2 inches in the drawing represent 1 foot in real life)

Step 2 (finding the dimensions of the herb garden on the scale drawing):

Real life dimensions are 2ft by 5ft so we multiply by the scale factor:

2ft = 2 x 1.2 = 2.4 inches

5ft = 5 x 1.2 = 6 inches

So the dimensions of the herb garden on the scale drawing are 2.4 by 6 inches.

A sample of a radioactive isotope had an initial mass of 540 mg in
the year 2009 and decays exponentially over time. A measurement
in the year 2011 found that the sample's mass had decayed to 300
mg. What would be the expected mass of the sample in the year
2021, to the nearest whole number?

Answers

Answer:

16 mg

Step-by-step explanation:

[tex]N_0[/tex] = Initial mass of sample = 540 mg

t = Time taken = 2 years

[tex]t_{1/2}[/tex] = Half life of isotope

N = Final mass of sample = 300 mg

Radioactive decay is given by

[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow \ln\dfrac{N}{N_0}=-\dfrac{\ln 2}{t_{1/2}}t\\\Rightarrow t_{1/2}=-\dfrac{\ln2}{\ln\dfrac{N}{N_0}}t\\\Rightarrow t_{1/2}=-\dfrac{\ln2}{\ln\dfrac{300}{540}}2\\\Rightarrow t_{1/2}=2.358\ \text{years}[/tex]

In 2021 the number of years passed from 2009 would be 12 years

[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow N=540e^{-\dfrac{\ln 2}{2.358}12}\\\Rightarrow N=15.86\approx 16\ \text{mg}[/tex]

The expected mass of the sample in the year 2021 would be 16 mg.

At a bakery, each pecan braid has 30 more milligrams
of sodium than each chocolate pastry. If 3 pecan
braids and 4 chocolate pastries have a total of 1840
milligrams of sodium, how many milligrams of
sodium does a pecan braid have?

Answers

Answer:

1840 minus 90

1750 divided by 7

Each chocolate pastry has 250 milligrams of sodium

Each pecan braid has 280 milligrams of sodium.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

/ Division operation: Divides left-hand operand by right-hand operand

For example 12/2 = 6

Given that each pecan braid has 30 more milligrams of sodium than each chocolate pastry

If 3 pecan braids and 4 chocolate pastries have a total of 1840 milligrams of sodium.

So, the number of milligrams of sodium present in chocolate pastry as

⇒ 1840 - 90

⇒ 1750

1750 milligrams of sodium are present in chocolate pastry.

Now, the number of milligrams of sodium present in chocolate pastry as

⇒ 1750/7

1750 divided by 7

Each chocolate pastry has 250 milligrams of sodium.

So, each pecan braid has 280 milligrams of sodium.

Parallelogram PQRS is shown on the coordinate grid. Parallelogram PQRS is dilated with the origin as the center of a dilation using the rule (x, y) → (1.5x, 1.5y) to create parallelogram P'Q'R'S'.

Which statement is true?

A) Parallelogram P'Q'R'S' is larger than parallelogram PQRS, because the scale factor is greater than 1.
B) Parallelogram P'Q'R'S' is smaller than parallelogram PQRS, because the scale factor is less than 1.
C) Parallelogram P'Q'R'S' is smaller than parallelogram PQRS because the scale factor is greater than 1.
D) Parallelogram P'Q'R'S' is larger than parallelogram PQRS, because the scale factor is less than 1.

Answers

Answer:

C) Parallelogram P'Q'R'S' is smaller than parallelogram PQRS because the scale factor is greater than 1.

Step-by-step explanation:

1.5x, 1.5y is greater than 1 for the value of x.y

The correct answer will be A

Explanation:
In terms of PQRS, the parallelogram will be seen as the ratio x:1 and y:1 The new figure, P’Q’R’S will have a ratio of x:1.5 y:1.5.

Because P’Q’R’S has a larger ratio of that than the original parallelogram, the resulting figure will be larger than the original shape PQRS.

(This can also be proven in terms of dilating by a scale factor of 0.5, as this will be a smaller figure than that of the original, further proving the claim.

what is this 59 divided 535

Answers

Answer:

9.07 [Rounded]

Step-by-step explanation:

535 divided by 59 is 9.07, which I rounded.

The value of the division 535 ÷ 59 is 9 with a remainder of 4 and the decimal form can be expressed as 9.067.

To find the value of division 535 ÷ 59, we can perform a long division.

To perform the calculation, we can use long division:

59 ) 535 ( 9

     - 531

     ______

         4

Divide the first digit of the dividend (5) by the divisor (59). Since 5 is less than 59, we bring down the next digit, making it 53.

Divide 53 by 59. The result is 0, as 53 is less than 59.

Bring down the next digit, making it 535.

Divide 535 by 59. The result is 9, as 59 can go into 535 nine times.

Multiply 9 by 59, which equals 531.

Subtract 531 from 535, which gives us a remainder of 4.

Therefore, the value of the division 535 ÷ 59 is 9 with a remainder of 4.

In decimal form, the division can be expressed as 9.067, indicating that 59 goes into 535 nine times with a remainder of 4.
