How do you write 13.8 in standard form. Word form and expanded form

Answers

Answer 1

Answer:

Answer and explanation:

To find : How do you write 13.8 in standard form, word form and expanded form ?

Solution :

According to place value system,

Tens Ones Tenths

1 3 8

The standard form of the number 13.8 is

$13.8=138* 10^(-1)=1.38* 10^(1)$

The expanded form of the number 13.8 is

$13.8=1* 10+3* 1+8* (1)/(10)$

$13.8=10+3+0.8$

The word form of the number 13.8 is

13.8 = Thirteen and eight tenths.

Answer 2

Answer:

Standard Form : 13.8 times 10^0 or just 13.8 because 10^0 is technically 1

Expanded Form : 10+3+0.8

Word Form : thirteen and eight tenths

Explain how you can use the triangle sum theorem to find the measures of the angles of an equilateral triangle

Answers

The triangle Sum Theorem says that the sum of all the angles in a triangle has to equal 180 degrees. Since all three sides (and, consequently, angles) in an equilateral triangle are the same, you can divide 180 by 3 to find the measure of any angle of an equilateral triangle (60 degrees).

Which equation can be used to calculate the area of the shaded triangle in the figure below?A rectangle with a length of 18 feet and width of 4 feet. A diagonal cuts the rectangle into two halves. One of the triangular halves is shaded.
(1 point)

2(18 + 4) = 44

fraction 1 over 2 (18 + 4) = 11

2(18 × 4) = 144

fraction 1 over 2 (18 × 4) = 36

Answers

Answer:

fraction 1 over 2 (18 × 4) = 36

$\because$ Area of standard triangle

$= (1)/(2) * base* height.$

Where,

Base of triangle = lenght of rectangle = 18 feet

Height of triangle = width of rectangle = 4 feet

It is because the slopes is rise over run. I rose 1 and ran 6.

What is the slope of the line? What does the slope represent?

Answers

The slope of a line characterizes the direction of a line. The find he slope, you divide the difference of the y coordinates of 2 points on a line by the difference of the x coordinates of those same 2 points

Answer:

the slope of the line represents the dna of a function. the Y axis uses the information to identify its own location based off of x's location

Jesse drives to work. The distance Jesse’s car travels (d) on a number of gallons of gas (g) is given by the equation d = 15g. The constant of proportionality in terms of distance traveled per gallon of gas is

a. 15
b. 5
c. 1
d. 1/15

Answers

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Distance traveled by Jesse's car = d

Number of gallons used = g

The relation between distance and number of gallons used is given by

$d=15g$

We need to find the constant of proportionality in terms of distance traveled per gallon of gas.

So, Constant of proportionality = $(Distance\ traveled)/(Gallon\ of\ gas)=(d)/(g)$

Since we have

$d=15g\n\n(d)/(g)=(1)/(15)=Constant\ of\ proportionality$

Hence, Option 'd' is correct.

What’s 48 rounded to the nearest ten

Answers

Answer:

Step-by-step explanation:

When you around to the nearest ten, you look at the ones digit, which in this case, is 8. Since that is 5 and above, you would have to round the 4 in the tens digit up to 5, resulting in 50.
