Which pairs of triangles appear to be congruent? Check all that apply.

Answer:

y=5,2 and -3

we have to put the values of X and then solve the equation.

Answer:

8x + 2y

Step-by-step explanation:

12x + 3y = 8 you need to transfer the no. 8 to left since it's positive, it will be negative once you tranfer that and the result is this 8x + 3y -8 =0. Then do it again on the second given, -4x = y + 8.

Tranfer the y variable to left, y is positive then it will be a negative. No need to transfer the no. 8. Then the result would be -4x - y + 8=0

To this solve this, wrote it like this:

12x + 3y –8

-4x - y + 8

——————

8x + 2y

Each chocolate pastry has 250 milligrams of sodium

Each pecan braid has 280 milligrams of sodium.

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.

Answer:

143 acres.

Step-by-step explanation:

To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.

To find a percent of a number, multiply the percent by the number.

0.2% is equal to 0.002.

73,000 x 0.002 = 143

So, 143 acres of the forest is old-growth trees.

Answer:

He drove 350 miles.

Step-by-step explanation:

I need points.

Brady drove 16.67 miles extra.

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.

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.

Find the value of the following division:

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.
