Answer:

1.535

Step-by-step explanation:

"one and nine-tenths" is 1.9

We SAY one point nine, but the official way to say the number is one and nine tenths. The one is a whole one. The "and" is the where the decimal point goes and the first place to the right of the decimal is the tenths place.

"three hundred sixty five thousandths" is 0.365

The second decimal place is the hundredths place, just fyi but its not in this problem. The third decimal place is the thousandths place.

1.9 - 0.365 is your question.

if you are allowed to use a calculator, just punch that in. If you are not allowed to use a calculator, then be sure to line up the decimal point when you subtract. Put 1.900 on top and subtract 0.365 and line up the decimal!

7. a. \(\displaystyle 25°\)

Step-by-step explanations:

10. Both segments are considered congruent, so turn both expressions into an equation:

\(\displaystyle 3x - 5 = x + 7 \hookrightarrow \frac{-12}{-2} = \frac{-2x}{-2} \\ \\ 6 = x\)

Plug this back into the equation to get \(\displaystyle 13\)on both sides.

9. All edges in a square obtain congruent right angles and edges, so set \(\displaystyle 45\)equivalent to the given expression:

\(\displaystyle 45 = 2x + 5 \hookrightarrow \frac{40}{2} = \frac{2x}{2} \\ \\ \boxed{20 = x}\)

8. Both angles are considered supplementary, so turn both expressions into an equation and set it to one hundred eighty degrees:

\(\displaystyle 180 = (4x - 15)° + (x + 30)° \hookrightarrow 180° = (15 + 5x)° \hookrightarrow \frac{165}{5} = \frac{5x}{5} \\ \\ \boxed{33 = x}\)

7. In this rectangle, segment EO is a segment bisectour, making these angles Complementary Angles. Therefore, set an equation up to find its complement:

Find the area of the full circle:

Area = pi x r^2

Area = 3.14 x 17^2

Area = 907.46 square units

A full circle is 360 degrees. The sector is 120degrees.

Multiply the area of the circle by the sector degrees/ full circle degrees

907.46 x 120/360 = 302.486 square units round off as needed.

Answer:

289/3\(\pi\) m² or 302.6400923... m²

Step-by-step explanation:

These type of questions are very simple, you just have to know how to approach them properly. I'll give you the general structure using this as an example for your understanding.

The general structure goes like this:

Area of a circle is \(\pi r^{2}\), so \(\pi\)×17² = 289\(\pi\) m²

The angle is 120° out of 360°, think of a sector as the percentage of the area of the circle.

120/360 = 1/3

1/3 × 289\(\pi\) = 289/3\(\pi\) m² or 302.6400923... m²

The coordinate vector of vector a = [2, 3, 4, 5] with respect to the basis B = [e22, e21, e12, e11] of M22 is [3, 4, 5, 2].

To find the coordinate vector, we need to express vector a as a linear combination of the basis vectors. The given basis B represents the standard basis for a 2x2 matrix.

Let's break down the process step by step:

Start with the basis vectors: e22, e21, e12, e11.

Express vector a as a linear combination of the basis vectors:

a = 2 * e22 + 3 * e21 + 4 * e12 + 5 * e11

The coefficients in front of each basis vector represent the coordinates of a with respect to the basis B.

Therefore, the coordinate vector of a with respect to B is [2, 3, 4, 5].

However, it's important to note that the given basis B is not the standard basis for a 2x2 matrix. The standard basis for a 2x2 matrix consists of the following vectors: e11 = [1, 0, 0, 0], e12 = [0, 1, 0, 0], e21 = [0, 0, 1, 0], e22 = [0, 0, 0, 1].

Since 50 is an even number, we know that x will be even if y is even (50 times an even number is still even) and odd if y is odd (50 times an odd number is odd). Therefore, the only answer choice that must be odd is x+y.

Given that x and y are integers and x = 50y + 69, let's determine which of the following expressions must be odd.

1. xy: Since x is odd (50y + 69), when it is multiplied by any integer y, the result will always be odd. Therefore, xy must be odd.

2. x + y: If x is odd, adding it to an even integer (y) would result in an odd number. However, adding it to an odd integer (y) would result in an even number. Therefore, x + y does not necessarily have to be odd. xy: We can't determine if this is odd or even without knowing the values of x and y.
- x+y: This expression is always odd. To see why, consider two cases:

If x and y are both odd, then x+y is even+odd=odd.
If x and y are both even, then x+y is even+even=even.
If one of x and y is odd and the other is even, then x + y is odd + even =odd.

3. x+2y: We can't determine if this is odd or even without knowing the values of x and y.
3x-1: This expression will be odd if x is odd (3 times an odd number is odd) and even if x is even (3 times an even number is even).
3x+1: This expression will be odd if x is even (3 times an even number plus 1 is odd) and even if x is odd (3 times an odd number plus 1 is even).
x + 2y: Since x is odd and 2y is always even, their sum must be odd. Therefore, x + 2 y must be odd.

4. 3x - 1: This expression is odd, since 3x will always be odd (as x is odd) and subtracting 1 from an odd number results in an even number. Therefore, 3x - 1 does not necessarily have to be odd.

5. 3x + 1: This expression is odd, since 3x will always be odd (as x is odd) and adding 1 to an odd number results in an even number. Therefore, 3x + 1 must be odd.

In conclusion, the expressions that must be odd are xy, x + 2y, and 3x + 1.

The perimeter of the triangle is 40 centimeters, which corresponds to answer choice G, 43 cm, option opt G is correct.

To find the perimeter of the triangle, we need to add the lengths of all three sides.
Given that the ratio of the side lengths is 4:7:10,

and the longest side is 40 centimeters,

we can set up the equation:
4x + 7x + 10x

= 40
Combining like terms,

we have:
21x = 40
Dividing both sides by 21,

we find:
x = 40/21
Now, we can find the lengths of the three sides by multiplying x with the respective ratios:
Side 1:

4x = 4 * (40/21)

= 160/21
Side 2:

7x = 7 * (40/21)

= 280/21
Side 3:

10x

= 10 * (40/21)

= 400/21
Adding all three sides together,

we get:
(160/21) + (280/21) + (400/21)

= 840/21

= 40
The perimeter of the triangle is 40 centimeters, which corresponds to answer choice G, 43 cm,option opt G is correct.

The perimeter of the triangle is 84 centimeters, which corresponds to option H.

To find the perimeter of the triangle, we need to determine the lengths of all three sides.

Given that the ratio of the measures of the sides is 4:7:10, we can represent the lengths of the sides as 4x, 7x, and 10x, where x is a constant.

We are also given that the longest side of the triangle is 40 centimeters, which corresponds to the side with a length of 10x.

To find the value of x, we can set up the following equation:

10x = 40

Dividing both sides of the equation by 10, we get:

x = 4

Now that we have the value of x, we can determine the lengths of the other two sides:

The length of the first side is 4x, which is 4 * 4 = 16 centimeters.
The length of the second side is 7x, which is 7 * 4 = 28 centimeters.

To find the perimeter of the triangle, we add up the lengths of all three sides:

16 + 28 + 40 = 84 centimeters.

Therefore, the perimeter of the triangle is 84 centimeters, which corresponds to option H.

Answer:

A. ∠N = ∠I

B. GH = LM

C. ∠M= ∠H

E. IH = NM

Step-by-step explanation:

The given statement "△GHI = △LMN" means that triangle GHI is congruent to triangle LMN. Congruent triangles have the same size and shape. Therefore, corresponding sides and angles of the triangles will be equal.

To determine which congruence statements are correct, we need to identify the corresponding sides and angles of the triangles. The corresponding sides and angles are those that are in the same position in each triangle. For example, side GH corresponds to side LM, angle N corresponds to angle I, and so on.

Using this information, we can check each statement:

A. ∠N = ∠I: This statement is true because ∠N and ∠I are corresponding angles in the congruent triangles.

B. GH = LM: This statement is true because GH and LM are corresponding sides in the congruent triangles.

C. ∠M= ∠H: This statement is true because ∠M and ∠H are corresponding angles in the congruent triangles.

D. IG = LM: This statement is false because IG and LM are not corresponding sides in the congruent triangles.

E. IH = NM: This statement is false because IH and NM are not corresponding sides in the congruent triangles.

F. ∠L = ∠I: This statement is false because ∠L and ∠I are not corresponding angles in the congruent triangles.

Therefore, the correct congruence statements are A, B, and C.
