Answer:

1.5 * 10^(-4) is the scientific notation.....

Answer:

(8x-7)(8x+7)

Step-by-step explanation:

64x²-49

(8x)²-7²

(8x+7)(8x-7) (using a²-b²=(a+b)(a-b)

Or

(8x-7)(8+7)

Answer:

x = -4

Step-by-step explanation:

The first equation tells us what y is equal to. We then substitute wherever there is a y with what y equals.

y = -2x - 9

6x - 5y = -19

6x - 5(-2x-9) = -19

6x + 10x + 45 = -19

16x + 45 = -19

16x = -64

x = -4

Answer: Choice A) Alternate exterior angles are congruent

This is due to the alternate exterior angles theorem.

A more in depth answer would involve a multiple number of paths to take. One such path could have us noticing the following two properties

Both congruences are due to the vertical angle theorem.

Furthermore,

angle 4 = angle 5

because they are alternate interior angles

Then by the transitive property, we effectively connect the dots or the chain links to get to angle 1 = angle 8. We can also use the substitution property as well.

---------------

Side note: angles 1 and 8 are outside the parallel lines 'a' and m, so they are considered exterior angles. Also, they are on alternating sides of the transversal line t. These two facts lead to angles 1 and 8 being alternate exterior angles.

Answer:

interior angles are congruent

Answer:

Liam would have to buy five packs of burgers and three packs of buns

Step-by-step explanation:

Buns- 10 x 3 = 30

Hamburgers- 6 x 5 = 30

Answer:

six

Step-by-step explanation:

It's six because the burgers are only six and buns are ten,he also wants all to be equal so he would vu six of each of the items

Answer:

39.6 ft.

Step-by-step explanation:

Height of the top of the goal post would be x + 5.5

So for we need to calculate x first,

For x:

[tex]tan\ \theta = \frac{perpendicular}{base}\\\\tan\ 61=\frac{x}{20}\\\\20*tan61=x\\\\x=20*1.732\\\\x=34.64\ ft[/tex]

So height of the top of the goal post would be 34.64 + 5.5 which is

39.64 ft. rounding it to nearest tenth would be 39.6ft.

Answer:

7.436  ×  10 ^6

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps!

Answer:

D. 1/5^15

Step-by-step explanation:

When an exponent is negative you need to get the reciprocal to make it positive.

Answer: you chose the correct answer, d, if the exponent is negative you need to find it’s reciprocal

Step-by-step explanation: 5 is a positive number but the exponent is not, in order for it to be positive the reciprocal is 1/5 because you are basically flipping the number 5 (which is equal to 5/1)

Answer:

Step-by-step explanation:

Answer:

[tex]t=\frac{x}{7}[/tex]

Step-by-step explanation:

You need to isolate the variable t. Use inverse operations for this.

7t can be seen as 7×t, and the opposite of multiplication is division. Divide both sides by 7:

[tex]\frac{7t}{7}=\frac{x}{7}\\\\t=\frac{x}{7}[/tex]

The common term 7 on the left side cancels out.

Answer:

Step-by-step explanation:

The number of people who have two-course meal is (10 - x)

Correct equation is:

Solving for x:

Answer:

Answers:

1) 15x + 12(10 - x) = 141

2) 7 and 3

15x + 12(10 - x) = 141

15x + 120 - 12x = 141

3x = 141 - 120

3x = 21

x = 7

answer:

the answer is -3 and 8

Step-by-step explanation:

we will place -3 in the equation

(x+3)(x-x)=0

(-3+3)=0 (because -3+3 will cut down together)

we will place two 8(eights) in the equation

(8-8)=0

final answer is

(0)(0)=0

so -3 and 8 fits well in the equation
