2^7.19

Which Choice Is Equivalent To The Expression Below?2^7.19

Answers

Answer 1

Answer:

B

Step-by-step explanation:

Exponents Law:

[tex]a^{m}*a^{n} = a^{m+n}[/tex]

In exponent multiplication, if bases are same, add the powers(exponents).

Write 7.19 in expanded form: 7.19 = 7 + 0.1 + 0.09. Now apply the exponent rule.

[tex]2^{7.19}=2^{7+0.1+0.09}\\\\=2^{7}*2^{0.1}*2^{0.09}\\\\= 2^{7}*2^{\frac{1}{10}}*2^{\frac{9}{100}}[/tex]

Hello! I hope this helps you!

If you are to simplify the expression, you’d be getting the answer of:

8x-2

before distributing the negative:

(7x2 + 3x) - (8x2 - 5x)

after distributing the negative:

7x2 + 3x - 8x2 + 5x

now add like terms:

7x2 + 3x - 8x2 + 5x

-x2 + 8x

or

8x - x2

Answers

Answer:

The 3rd option is correct.

Step-by-step explanation:

This is because of an exponent rule that goes:

(xy)^z = x^z(y^z)

The whole thing gets raised to the power. Therefore only the 3rd one works (ps. if you can mark as brainliest that would be amazing, but if not that's fine)

Answer:

a = 30b = 15c = 3d = 30e = 10f = 20

Step-by-step explanation:

The acute angles are all 60°, and the obtuse angles are all the supplement of that, 120°.

Working from the left, we have ...

  a +30 = 60  ⇒  a = 30

  30 +2b = 60  ⇒  b = 15

  5b -5c = 60  ⇒  15 -c = 12  ⇒  c = 3

  10c +d = 60  ⇒  d = 30

  2d +6e = 120  ⇒  60 +6e = 120  ⇒  e = 10

  4f +4e = 120  ⇒  f +10 = 30  ⇒  f = 20

Answer:

The statements that must be true are:

XY and JK form four right angles ⇒ B

XY ⊥ JK ⇒ C

JP = KP ⇒ E

m∠JPX = 90° ⇒ F

Step-by-step explanation:

From the given figure

∵ Line XY is the perpendicular bisector of the line segment JK

→ That means line XY is the line of symmetry of the line segment JK

XY ⊥ JK ⇒ C

∵ XY ∩ JK at point P

P is the midpoint of JK

∵ XY ⊥ JK

∴ ∠JPX, ∠KPX, ∠JPY, and ∠KPY are right angles

XY and JK form four right angles ⇒ B

∵ The measure of the right angle is 90°

∴ m∠JPX = m∠KPX = m∠JPY = m∠KPY = 90°

m∠JPX = 90° ⇒ F

∵ P is the midpoint of JK

JP = KP ⇒ E

Jared started a new job. On the first day he had orientation and worked for 2 hours. On the second day he trained for 4 hours. After that, Jared worked 8 hours each day. If his first paycheck shows that he is being paid for 94 hours of work, how many days did he work a full 8-hour day?

Answers

Answer:

Jared worked 11 days as full 8-hour days.

Step-by-step explanation:

We have:

First day = 2 h

Second day = 4 h

After that = 8 h each day    

Since his paycheck shows 94 hours of work, we can find the number of days that he works 8-hour day:

[tex] 94 h = 2 h + 4 h + 8 h*x [/tex]

Where x is the number of days that he works 8-hours.

[tex] 8 h*x = 88 h [/tex]

[tex] x = \frac{88 h}{8 h} = 11 [/tex]

 

Therefore, Jared worked 11 days as full 8-hour days.

One smaller cube labeled with fish food with dimensions of one-quarters feet on each side. Larger cube labeled shipping box with dimensions of length 3 and three-fourths feet; width of 3 feet; height of 3 and one-quarters feet. Part 1: Understanding Volume

Answers

Answer:

Given: Length of smaller cube= 1/4 feet each side

Length of larger cube= 3.75 feet

Width of larger cube= 3 feet

Height of larger cube= 3.25 feet

Step-by-step explanation:

Volume of a cube= length * width * height

Volume of a larger cube= 3.75 * 3 * 3.25 cubic foot

Volume=36.5625 cubic foot

Volume of smaller cube= length * length * length (as length is same on each side)

Volume of smaller cube= 1/4 * 1/4 * 1/4

Volume of smaller cube= 1/64 cubic foot

Hence, volume is calculated.

Two tour groups are visiting an aquarium. There are 20 children in one group and 22 children in the other. Along with the 2 group leaders, there are 5 additional adults between the two groups. If the cost per child is $9.00 and the total for both groups is $490, what is the cost per adult?

Answers

Answer:

The cost per adult is $16.

Step-by-step explanation:

Given that:

Total number of children = 20+22 = 42 children

Total number of adults = 2 + 5 = 7 adults

Total cost for both groups = $490

Cost per child = $9.00

Cost of children ticket = 9.00*42 = $378

Cost of adult tickets = 490-378 = $112

This is the cost for 7 adult tickets.

Cost per ticket = [tex]\frac{112}{7}[/tex] = $16

Hence,

The cost per adult is $16.

The graphs of the equations 4x - y = 6 and x + y = 4 intersect at
the point whose coordinates are

Answers

Answer:

The graphs of the equations 4x - y = 6 and x + y = 4 intersect at  the point whose coordinates are (2,2)

Step-by-step explanation:

The graphs of the equations 4x - y = 6 and x + y = 4 intersect at  the point whose coordinates are?

We need to find the values of x and y by solving the system of equations.

The values of x and y are the point of intersection of those lines.

We have:

[tex]4x - y = 6--eq(1) \\x + y = 4--eq(2)[/tex]

Adding both equations and finding value of x

[tex]4x - y = 6\\ x + y = 4\\-----\\5x+0y=10\\5x=10\\x=\frac{10}{5}\\x=2[/tex]

We get, the value of x: x=2

Now, putting value of x in equation 2 to find value of y:

[tex]x+y=4\\Put\:x=2\\2+y=4\\y=4-2\\y=2[/tex]

So, we get y=2

Therefore we get x=2 and y=2

The solution set is: (2,2)

So, The graphs of the equations 4x - y = 6 and x + y = 4 intersect at  the point whose coordinates are (2,2)
