Answer:

Step-by-step explanation:

Answer:

a. 1

b. any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1

Step-by-step explanation:

Answer and explanation:

a) This value is equal to one because it is just the number divided by itself.

b) Since any number divided by itself is equal to 1, 6^3/6^3 also has to equal to one. This also means that when we bring the 6^3 up to the numerator, the equation 6^3-3, which simplifies into 6^0 also has to equal 1, because it is equivalent to being divided by itself.

Answer:

x = - 18

Step-by-step explanation:

Let certain number = x

The difference between half of a certain number and seven

x/2 - 7

is the same as

=

with adding two to that number

x + 2

Find the number

x/2 - 7 = x + 2

x - x/2 = - 7 - 2

( 2x - x ) / 2 = -9

2x - x = -18

x = - 18

Answer: x= 14

Step-by-step explanation: look at transversal ED. Angle E and angle D are alternate interior angles of this transversal. Alternate interior angles are equal. Now we need to find angle measure of D to solve. The triangle angle sum theorem states that all interior angles of a triangle sum to 180 degrees. 50+ 48 + D =180.

Measure of angle D is 82. Now that we have the two alternate interior angles, we set them equal to each other to solve.

6x-2= 82. Add 2 to both sides. 6x = 84. Divide both sides by 6. X =14

Answer:

p=19

Step-by-step explanation:

since the instructions say that ([tex]x^{13}[/tex])([tex]x^{6}[/tex]) is equivalent to [tex]x^{p}[/tex], we can make the equation:

([tex]x^{13}[/tex])([tex]x^{6}[/tex])=[tex]x^{p}[/tex]

now, apply the laws of exponents; [tex]a^{m} * a^{n} =a^{m+n}[/tex]

in that case, since we're multiplying x to the 13th power by x to the 6th, the result is [tex]x^{13+6}[/tex], which is [tex]x^{19}[/tex]

the equation now:

[tex]x^{19}[/tex]=[tex]x^{p}[/tex]

since the exponents are at the same base, we can solve the equation

19=p

so p is 19

hope this helps :)

Answer:

84 and 140

Step-by-step explanation:

Jack chooses two numbers between 50 and 150

The two numbers have a Lowest Common Multiple (LCM) of 420

Factors of 420 between 50 to 150

= 60, 70, 84, 105, 140

We are also told that:

They have a Highest Common Factor (HCF) of 28

Hence, we find out of the factors above, which numbers can be divided by 28 without having any remainder.

60/28 = 2.1428571429

70/28 = 2.5

84/28 = 3

105/28 = 3.75

140/28 = 5

Therefore, the two numbers are

84 and 140

Answer:

It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).

Answer:

1 foot

Step-by-step explanation:

he used up 3/4 of it so 16x0.75=12 to find remaining length subtract 16-12=4

so there is a 4 foot board left then he gives 1/4 of that to his brother 4x0.25=1

so he gave his brother 1 foot of wood

Answer: Y = 7/8x+ 2.25

Step-by-step explanation:

Answer:

8y=21x

Step-by-step explanation:

i'm not sure how to draw this out in a picture but the equation is above.

like the question states, Cassidy paints 8 faces in every 21 minutes. the amount of time she spends painting one face would be figured out by dividing 21 by 8 giving you 2.625minutes so i would just say around 3 minutes. so to draw a picture maybe just draw 8 faces and then circle them and say 21 minutes and then put x (to show the time she spent painting each face) under the faces in the picture and then show your work solving this.

in order to find out the ratio of time spent drawing one person's face we have to take the information given and divide the total of 21 minute span by the 8 different faces she painted in order to find how long she spends on 1 face.

hope this helps, if it did please make sure to leave a like, rate, and give me the brainliest if possible!

thanks have a great day!

Buying 10 cans for $5.80 is the best deal.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to the question

We have

Cost of eight cans is $4.88

⇒ cost of one can = [tex]\frac{4.88}{8}[/tex] = $0.61

Cost of 10 cans is $5.80

⇒ cost of one can = [tex]\frac{5.80}{10}[/tex] =$0.58

Cost of 3 cans is $7.20

⇒ cost of one can = [tex]\frac{7.20}{3}[/tex] = $2.4

Hence, buying 10 cans for $5.80 is the best deal.
