Answer:

P-E-M-D-A-S

Step-by-step explanation:

Ok, so start with what i call "P-E-M-D-A-S"

P: parentheses | Also known as these: ( )

E: exponents | Its a small number by another number, like the 3 on your screen

M: Multiply | Also Known as   x or a dot

D: Divide | i forgot how to make it

A: Add | also known as +

S: Subtract | also known as -

now go in order to solve it, it makes it much more easy!

Answer:

49 is your answer

Step-by-step explanation:

let's do b-pemdas

brackets

parentheses

e(I forgot the name for it but it's basically a small number next to the big number)

Multiply

Divide

Add

Subtract

you do the equation in that order

so

2+8•7-(3^2)

we focus on (3^2)

that's 3•3 which equals to 9

so now the equation is

2+8•7-9

Now we focus on 8•7 which equals to 56

the equation now looks like

2+56-9

you then add 56 to 2 which equals to 58 and then subtract 9 from it so it should look like this

2+56=58

58-9= 49

and 49 is your answer

hope this help!!!

if you would give me brainliest that would help a lot!!

Answer:

3

Step-by-step explanation:

By going up 3 and right 1 you get 3/1, aka 3

The line of the equation is y=3x+2

Answer:

b= 7

Step-by-step explanation:

here's your solution

=> perimeter of rectangle = 62 cm

=> length = 24 cm

=> let width be (b)

=> perimeter of rectangle = 2(l + b)

=> 2(l + b ) = 62

=> 2(24 + b) = 62

=> 48 +2b = 62

=> 2b = 62 - 48

=> 2b = 14

=> b = 14/2

=> b = 7

Answer:

a

Step-by-step explanation:

the formula of the equation is y=mx+n; and if m=1/2 and n=-1 then it's y=1/2x-1

Answer:

a. Base area, B= 24 square units.

b. Volume, V = 96 cubic units.

Step-by-step explanation:

Given the following data;

Length of sides = 4 units

Width of sides = 6 units

Height = 4 units

a. To find the base area, B;

The base of a rectangular prism is a rectangle.

Area of rectangle, B = length * width

Area of rectangle, B = 4 * 6

Area of rectangle, B = 24 square units.

b. To find the volume;

Volume of rectangular prism = base area * height

Volume= 24 * 4

Volume = 96 cubic units.

Answer:

B = 24 square units.

V = 96 cubic units.

Answer:

(0, 4 ) and (2, - 4 )

Step-by-step explanation:

(2)

3x + 4y = 16 → (1)

- 3x + 2y = 8 → (2)

Adding (1) and (2) term by term will eliminate the x- term

0 + 6y = 24

6y = 24 ( divide both sides by 6 )

y = 4

Substitute y = 4 into either of the 2 equations and solve for x

Substituting into (1)

3x + 4(4) = 16

3x + 16 = 16 ( subtract 16 from both sides )

3x = 0 , then

x = 0

solution is (0, 4 )

(3)

2x - 4y = 20 → (1)

5x + 4y = - 6 → (2)

Adding (1) and (2) term by term will eliminate the y- term

7x + 0 = 14

7x = 14 ( divide both sides by 7 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (2)

5(2) + 4y = - 6

10 + 4y = - 6 ( subtract 10 from both sides )

4y = - 16 ( divide both sides by 4 )

y = - 4

solution is (2, - 4 )

Answer:

The answer is 36 and 225.

Step-by-step explanation:

36 is the square number of 6.

225 is the square number of 15.

Answer:

B,C,D are all isocele triangles

Step-by-step explanation:

Answer:

x=-2,-4 is your answer

x²+6x+8=0

doing middle term factorization

x²+4x+2x+8=0

x(x+4)+2(x+4)=0

(x+4)(x+2)=0

either

x=-4

or

x=-2

Answer:

6.67

Step-by-step explanation:

Here is 4 divided by 3/5 displayed mathematically

4

 ÷    

3

--

5

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

4 x 5

3

 =    

20

---

3

Thus, the answer to 4 divided by 3/5 in fraction form is:

20

---

3

To make the answer to 4 divided by 3/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

20 / 3 = 6.67

Answer:

4 ÷ 3/5 = 6.66666666667

3/5 ÷ 4 = 0.15

Answer:

0.8315 = 83.15% probability that a randomly selected gas station in France charges more than $5.30 per gallon

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average price for a gallon of gasoline in France is $5.54. The standard deviation is $.25.

This means that [tex]\mu = 5.54, \sigma = 0.25[/tex]

What is the probability that a randomly selected gas station in France charges more than $5.30 per gallon?

This is 1 subtracted by the pvalue of Z when X = 5.30. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{5.3 - 5.54}{0.25}[/tex]

[tex]Z = -0.96[/tex]

[tex]Z = -0.96[/tex] has a pvalue of 0.1685

1 - 0.1685 = 0.8315

0.8315 = 83.15% probability that a randomly selected gas station in France charges more than $5.30 per gallon

Answer:

You should study hard and look through the test first to answer the ones you do know and then go back to the ones you don't know. Also if you use any methods or anything related to help with math try to use those through. Therefore try your best and just prepare for it, and always have supplies.

Answer:

The answer is D because it is closer to zero so it is greater in value. For example if the number is further away from zero (and is negative) the value is less but if it’s closer it is greater and in positive numbers the rules are opposite
