Combining like terms!!
3.) 4x + 6 = 14

Answer:

0.81859

Step-by-step explanation:

We solve using z score method

The formula for calculating a z-score is is z = (x-μ)/σ,

where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Mean 0.8 pound

Standard deviation 0.25 pound

For x = 0.55 pound

z = 0.55 - 0.8/0.25

= -1

Probability -value from Z-Table:

P(x = 0.55) = 0.15866

For x = 1.3 pounds

Z = 1.3 = 0.8/0.25

= 2

Probability value from Z-Table:

P(x = 1.3) = 0.97725

The probability that a randomly selected zucchini will weigh between 0.55 pound and 1.3 pounds is

P(x = 1.3) - P(x = 0.8)

0.97725 - 0.15866

0.81859.

Answer:

Option D, 72

Step-by-step explanation:

Before touching the question, Let me tell you something about simple interest.

Simple Interest: It is something that is calculated for the additional amount paid on a loan amount. The formula for simple Interest is given by, SI = (P × R × T)/100 where, P specifies principal, R specifies rate, and T denotes time.

Now, Let's go for solving the question.

Simple Interest = P × R × T/100

0r, Simple interest = (720 × 5 × 2)/100

0r, Simple Interest = 72 × 2 × 5/10

0r, Simple Interest = 72

Hence, 72 is the required answer.

Answer:

the awnser is 30

Step-by-step explanation:

mario and peach equal the same, so you would have to do 36÷3 and that equals 12, so then you look at mario divided by toad, and you would do 12÷2 to get 6, so toad would be 6, and that make bowser 0. so it would be 12+0+12+6=30

The answer to this is / 7c -70

7c-70 is the Answer

first you want to do distributive property. since the -10 is on the outside of the parentheses, you multiply it by the numbers that are in the parentheses. After you do this, the equation should look like

50c-40c-70-3c

Then, you want to combine like terms. The 70 does not have a variable so you want to combine the one with exponents which are 50c,-40, and 3c

50-40 is 10. Then you would add the variable: 10c 10c-3c is 7c once all like terms are combined the equation should look like this:

7c-70

If Mr. Johnson is going to buy a 18 3/4 of turkey for Thanksgiving. The turkey cost $2.95 per pound at the grocery store. 11.06 is the closest estimate to the total cost of Mr. Johnson's turkey

percentage, a relative value indicating hundredth parts of any quantity.

Mr. Johnson is going to buy a 18 3/4 of turkey for Thanksgiving.

The turkey cost $2.95 per pound at the grocery store

We need to find the closest estimate to the total cost of Mr. Johnson's turkey (before taxes)

18 3/4 pound=18.75 pound

20% of $2.85=20/100×2.95

=0.2×2.95

=0.59

Now 0.59×18.75

=11.06

Hence 11.06 is the closest estimate to the total cost of Mr. Johnson's turkey (before taxes)

Answer:

I'm not sure if this is correct, but if I'm not mistaken, it should be 26.4 multiplied by 3/7.

Step-by-step explanation:

The reasoning is actually pretty simple. First, find the distance between points F and B.  (Hint: Use the Pythagorean Theorem) Then, take that distance, and multiply is by 3/7. Okay, 11.314. That means that the next point should be about 11.314 away from point F, and on the line between those points. Good Luck! I think you can figure out the rest.

Kim = 3x

Kim = 3(30)

Kim = £90

Answer: The answer is 148

Step-by-step explanation:

Angle CBA and ABD should add up to 180 degrees. So you just do 180-32=148

The measurement of the ∠ABD in the given figure is 148°.

Hence the correct option is D.

Given that are two lines AE and CD are intersecting at point B, making angle ∠ABC = 32°.

We need to find the measurement of the ∠ABD.

To find the measurement of the ∠ABD, we will use the concept of linear pair angles.

According to the figure, angles ABC and ABD are linear pair angles, that mean they are supplementary, or we can say their sum is 180°.

Therefore, setting up the equation.

∠ABC + ∠ABD = 180°

Plugging the value of angle ABC from the given information,

32° + ∠ABD = 180°

Subtracting 32 from both the sides,

∠ABD = 180° - 32°

∠ABD = 148°

Hence the angle ABD is equal to 148°.

Therefore, the correct option is D.
