Step-by-step explanation:

-1 3/7 • (-3 2/5)

Let's turn them both into fractions with no whole numbers to make this easier:

-10/7 • -17/5

Now we can multiply straight across much easier!

Two interior angles of a triangle each measure 34°. What is the measure of the third interior angle?
A. 146°
B. 292°
C. 56°
D. 112°

Answers

Answer:

D. 112

Step-by-step explanation:

Since we know that a triangle totals 180 degrees, we can easily figure out the third angle. Since each measure 34 degrees, simply multiply by 2. You get 68 degrees. Then you do 180-68 to get 112.

What is the area of the lawn in square meters?
F 108 m2
G 60 m2
H 72 m2
J 120 m2

Answers

Answer:

G) 60 m2

Step-by-step explanation:

1) Cut off the triangles and solve for the area of the rectangle.

    12 m x 4 m = 48m

2) Now that we have the big area of the rectangle, we just have to solve for the 2 triangles on the ends. Of the 18 m at the top, we uses 12 m to make the rectangle. That means there are 6 m that was not incorporated in the rectangle. Since there are 2 triangles, we can conclude that the base of each triangle is 3. Now we just have to use the equation for a triangle to find the area.

    4 m x 3 m x 1/2 = 6m (each triangle = 6m)

3) Add up all of the values to get the complete area

    48m + 6m + 6m = 60 m2

Naomi used 100 tiles to create a design. Blue tiles make up 1/2 of the design. Another 15 tiles are green, and 1/5 of the tiles are yellow. The rest of the tiles are red. How many red tiles did Naomi use in her design?
A. 15 tiles
B. 25 tiles
C. 65 tiles
D. 85 tiles

Answers

Answer:

Naomi used 15 red tiles in her design.

Step-by-step explanation:

We need to add the total number of tiles that we know to find out the unknown value of red tiles. The blue tiles make up 1/2 of the design, or 50 tiles. Next we will add the green tiles, which Naomi used  15 of, as stated.

So far, we have figured out how many blue and green tiles we have. (50 blue, and 15 green, which is a total of 65).

Now we need to calculate the number of yellow tiles, which equal 1/5 of the design. 1/5 of 100 is 20.

Now we add all of our tiles that we already know. We have 50 red + 15 green + 20 yellow which = 85.

Now to find the unknown value of red tiles, we subtract our 85 other tiles from the 100 total tiles, and the ends us up with 15 red tiles.

Hope this helps!!

Twenty-four 4-inch wide square posts are evenly spaced with 5 feet between adjacent posts to enclose a square field, as shown. What is the outer perimeter, in feet, of the fence? Express your answer as a mixed number.

Answers

Answer:

129 1/3

Step-by-step explanation:

According to Alcumus, "There are 20 square posts which are not on a corner, so there are $20/4=5$ square posts on each side, not including the corner posts. Including the corner posts, there are 7 posts on a side, which means that there are 6 five-foot gaps between posts. Altogether the length of a side is $7\left(\frac{1}{3}\right)+6(5)=32\frac{1}{3}$ feet. The perimeter of the square is four times the side length, so the perimeter is $4\cdot 32\frac{1}{3}=\boxed{129\frac{1}{3}}$ feet."

The outer perimeter is 129 1/3 feet.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For Example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Twenty-four 4-inch wide square posts are evenly spaced with 5 feet.

So, there are $20/4

                   =5$ square posts on each side, not including the corner posts.

and, including the corner posts, there are 7 posts on a side, which means that there are 6 five-foot gaps between posts.

Then, the length of a side is

= 7 1/3 + 6(5)

= 32 1/3 feet

and, The perimeter of the square

= 4 x 32 1/3

= 129 1/3 feet

:)

The scale factor for this dilation is 2

What is dilation?

The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger. The initial figure is referred to as the pre-image, and the new figure that results from dilatation is known as the image.

As per the given data:

We are given a diagram having 2 triangles, we need to find the scale factor for this dilation.

For finding the scale factor, we can find the ratio of the corresponding sides of the two triangles.

Scale factor for ΔG'H'I' and ΔGHI :

= [tex]\frac{H'I'}{HI}[/tex]

From the given graph, we can clearly observe that

H'I' = 8 + 4 = 12

HI = 4 + 2 = 6

[tex]\frac{H'I'}{HI}[/tex] =  [tex]\frac{12}{6}[/tex] = 2

Hence, The scale factor for this dilation is 2.

Step-by-step explanation:

Jaxon drank 2/5 = 0.2 = 4/10

Kesha drank 0.4 = 4/10

Luann drank 1/2 = 5/10

4/10 + 4/10 + 5/10 = 13/10 = 26/30

A proton is a very tiny particle inside an atom. The mass of a proton is

Answers

Answer:

Step-by-step explanation:

The mass of the proton in scientific notation is given by:

[tex]1.67 \times 10^{-24}[/tex]

A number in scientific notation has the following format:

[tex]y = a \times 10^b[/tex]

a is a number in the interval [tex][1, 10)[/tex].b is the power of 10. If the number is greater than 1, the power is positive. If the number is between 0 and 1, the power is negative.

In this problem, the number is: [tex]0.00000000000000000000000167[/tex].

To place into scientific notation, we need that [tex]a = 1.67[/tex].Moving the decimal point to after the 1, it would move 24 places, in a number between 0 and 1, thus [tex]b = -24[/tex]

Thus, the mass of the proton, in scientific notation, is of:

B. The number of grams of the radioactive isotope present after 1/2 year
C. The number of grams of the radioactive isotope present after 2 years
D. The final number of grams of the radioactive isotope present

Answers

D because The isotope is radioactive

The value 1500 in the expression represents option A. The original number of grams of the radioactive isotope present.

What are Expressions?

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given an exponential expression,

The number of grams of a radioactive isotope present after t years is 1,500(1/2)^t.

Here t is the number of years.

1/2 is the rate of decay of the isotope.

1500 is the initial amount.

We can say that the expression equals 1500 when t = 0.

But it is given that t > 0.

That is, 1500 is the amount which is equal to the original number of  grams of isotope.

Hence the number 1500 represents the original number of grams of the radioactive isotope present.
