The exponent 5¹⁵ is equivalent to the given expression 5¹⁰ · 5⁵. The correct answer would be an option (C).
What is an exponent?The exponent of a number represents the total time required to multiply that number. 8 8 8 may be stated as 83 since 8 is multiplied by itself three times. In this case, 3 is the 'exponent' or 'power' that indicates how many times 8 is multiplied by itself, and 8 is the 'base' that represents the integer being multiplied.
The exponent expression is given as:
5¹⁰ · 5⁵
We have to determine the equivalent exponent to the given expression.
As per the question, we have
5¹⁰ · 5⁵
Simplify using the exponent rule with the same base,
5¹⁰⁺⁵
Adding the powers in the expression, we get
5¹⁵
This exponent is equivalent to the given expression.

A piece of chocolate is 4/5 inch long. Meg lays 4 chocolate pieces end to end in a row. How many inches long is the row of chocolates ( please helpppppp) ( MAP test question)
Answer:
The length of row = 3.2 inches.
Step-by-step explanation:
The length of a chocolate = 4/5 inch
Total number of chocolate pieces placed = 4
Now we have given the length of one chocolate and it is required to find the total length of the row when four chocolates are placed end to end. So in order to find the length of the chocolate row we have to multiply the size of one chocolate by the number of chocolates.
The length of row = Length of one chocolate × number of chocolates
The length of row = 4/5 × 4
The length of row = 3.2 inches.
The piece of chocolate and the number of chocolates in a row can be represented using equations.
A row of chocolate is 3.2 inches long
Given that:
[tex]L = \frac 45[/tex] ---- Length of a piece
[tex]n =4[/tex] --- number of chocolate pieces
The length of the chocolate in a row is calculated as follows:
[tex]Length = n \times L[/tex]
So, we have:
[tex]Length = 4 \times \frac 45[/tex]
[tex]Length = 4 \times 0.8[/tex]
[tex]Length = 3.2[/tex]
Hence, a row of chocolate is 3.2 inches long

Given that, trapezoid FGHJ has vertices at F(2.-3), G(2, 4), H(6,4), and J(19, -3).
We need to find the area of the trapezoid.
What is the formula to find the area of trapezium?The area of a trapezium is defined as the number of unit squares that can fit into it and it is measured in square units (like cm², m², in², etc). A trapezium is a type of quadrilateral that has one pair of parallel sides(generally referred to as bases). The other pair of sides of a trapezium can be non-parallel and are known as legs. The area of a trapezium is the total space covered by a trapezium in a two-dimensional plane.
The area of a trapezium =1/2 (a+b)×h square units.
Now, area=1/2 (4+17)×6=33 square units
Therefore, the area of the trapezoid FGHJ is 33 square units.

You spend a total of 300 minutes doing math homework Monday through Friday. How many hours will you spend on math homework by the end of this semester (18 weeks)?
Answer:
90 hour
Step-by-step explanation:
300 minutes is for 1 school week
so if you multiply 300 minutes for 18 weeks it results as 5400 minutes.
300 × 18 = 5400 minutes
To get the number of hours you should divide 5400 minute by 60 minutes ( which is one hour )
5400 ÷ 60 =. 90 hours
You spent a total of 90 hours studying math in 18 weeks.
Amber is making a scale drawing of a movie screen. Her local theater is 60 ft wide and 200 ft tall in her scale drawing the screen has a width of 9 inches what will the height of her screen on her drawing be
Answer:
The height of her screen on her drawing must be 30 inches.
Step-by-step explanation:
The scale factor is obtained by dividing the drawn width by real width of the movie screen:
[tex]k = \frac{9\,in}{60\,ft}[/tex]
[tex]k = \frac{3\,in}{20\,ft}[/tex]
The drawn height of movie screen is the product of the scale factor and the real height of the movie screen:
[tex]h_{s} = \left(\frac{3\,in}{20\,ft} \right)\cdot (200\,ft)[/tex]
[tex]h_{s} = 30\,in[/tex]
The height of her screen on her drawing must be 30 inches.

Answer:
1. The star's mass is 3.0 x 10^32 kg.
2. The star's mass is 3.0 x 10^32 kg.
Step-by-step explanation:
1.
given:
The sun's mass is 2.0×10^30 kg.
mass of a star = 1.5×10^2 kg times the mass of the sun.
find:
Express the answer in Scientific notation.
mass of a star = 1.5×10^2 kg X 2.0×10^30 kg
mass of a star = 3.0 X 10^32 kg
therefore,
The star's mass is 3.0 x 10^32 kg.
===============================================
2.
(2.0 X 10^30) X (1.5 X 10^2)
Multiply the coefficients.
= (2.0 X 1.5)

= 10^30 + 10^2
= 10^32
Combine the results of the two operations.
(2.0 X 10^30) X (1.5 X 10^2) = 3.0 X 10^32
therefore,
The star's mass is 3.0 x 10^32 kg.

Answer:
25 questions
Step-by-step explanation:
First set up the equation.
[tex]\frac{20}{x} = \frac{80}{100}[/tex]
To get from 20 to 80 you have to multiply by a scale factor of 4, so do the same to the bottom as well.
Do the inverse and divide 100 by 4 to get x = 25.
There were 25 questions on Victoria's test.
