Answer:

[tex]3\sqrt{2}[/tex]/2

Step-by-step explanation:

first we take the square root of the top and bottom:

[tex]\frac{\sqrt{72} }{\sqrt{16} }[/tex]

The denominator is 4. The numerator is harder to solve. To solve, we need to look at the factors of 72.

72= 8 * 9. This means that [tex]\sqrt{72} =\sqrt{8} *\sqrt{9} \\[/tex]

We know that the square root of 9 is 3, so now we have

[tex]\frac{3\sqrt{8} }{4}[/tex]

We're almost done!

Since 8= 2*4, and the square root of 4 is 2,

[tex]\frac{3*2*\sqrt{2}}{4}[/tex]

last, we simplify and get

[tex]\frac{3\sqrt{2}}{2}[/tex]

Answer:

Yes, SAS.

Step-by-step explanation:

For my education system, there isn't such thing as SAS, ASA or etc. I just had to search it up what it was.

Congruent angles are angles with the same shape and size. The two triangles are congruent if you look carefully, after that I searched up and saw the different rules of triangles. I think that SAS might be the correct answer.

Answer:

80°

Step-by-step explanation:

According to angles rule,

100° + x = 180° [linear pair]

=> x = 180°-100°

=> x = 80°(Ans)

Answer:

C. 8 miles per hour

Step-by-step explanation:

1/24th of an hour is 2.5 minutes, taking Diego 2.5 minutes to ride 1/3rd of a mile

2.5 x 3 (to signify how long it would take Diego to ride a mile) = 7.5 minutes

60 divided by 7.5 = 8

Therefore, Diego's speed in MPH is 8.

The value of  [tex]9^{(-1/2)[/tex] is equal to 1/3.

To estimate [tex]9^{(-1/2)[/tex], we can apply the rule of fractional expounders, which states that a( m/ n) is equal to the utmost root of a raised to the power of m.

In this case, we've [tex]9^{(-1/2)[/tex], which means we need to find the square root of 9 raised to the power of-1.

The square root of 9 is 3, so we have

[tex]9^{(-1/2)[/tex]= ( √( 9))⁻¹ = 3⁻¹

The exponent -1 indicates the complementary of a number.

So, 3⁻¹ is equal to 1/3.

Thus, [tex]9^{(-1/2)[/tex] is equal to 1/3.

Answer:

Day 6

Step-by-step explanation:

Every 3 days 1 pound of hay is used every day 1 pound of grain is used. There are 10 pounds of grain and 8 pounds of hay. On the 6th day there are 6 pounds of hay left and 6 pounds of grain left.

The number of days after which the amount of hay and the grain will be the same is 12 days.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Hay = 8 pounds

1 pound = 3 days

From the graph,

Grain = 10 pounds

5 pounds left after 10 days

1 pound = 2 days

Now,

The number of days x after which the pounds left will be the same.

(-1/3)x + 8 = 10 - (1/2)x

(-1/3)x + (1/2)x = 10 - 8

(-2x + 3x)/6 = 2

x/6 = 2

x = 12

Thus,

After 12 days the hay and the grain left over will be the same.

Answer:

(1/2) {ad - cb}  both expressions

Step-by-step explanation:

Notice that the area of the triangle in question can be calculated as the area of the larger right angle triangle OSQ MINUS the area of the smaller right angle triangle OPR, and MINUS the area of the trapezoid RSQP.

Given the coordinates of the given points, the formulas for area of triangles and of trapezoid, we have the following area subtractions:

1/2 (a + c) (b +d) - 1/2  a* b - 1/2  c (b + b + d)=

= (1/2) { ab + ad + cb + cd - ab - 2 cb -cd } =

= (1/2) {ad - cb}

On the other hand the matrix expression is giving you 1/2 of the determinant of the given matrix  such determinant is: ad - cb

Then we see that the equality is correct since (1/2) of the determinant is also :

(1/2) {ad - cb}

Answer:

9g -5h - 8

Step-by-step explanation:

We first have to get everything out of the parentheses, so we take the negative that is surrounding the parentheses and apply it to the equation inside of it, giving us this: 5g - 2h - 3h - 8 + 4g

Then, all we need to do is simplify it into this expression: 9g -5h - 8

Answer:

9g-5h-8

Step-by-step explanation:

(5g-2h)-(3h+8-4g)

Opening the brackets

5g-2h-3h-8+4g

Step-by-step explanation:

=======================================================

Explanation:

Since the center of dilation is (0,0), we multiply each coordinate of point B by the scale factor 1/3.

The coordinates of point B are x = 5/3 and y = -7/2

So we have

(1/3)*x = (1/3)*(5/3) = (1*5)/(3*3) = 5/9 as the new x coordinate

and

(1/3)*y = (1/3)*(-7/2) = (1*(-7))/(3*2) = -7/6 as the new y coordinate

The point (5/3, -7/2) moves to (5/9,  -7/6)

Answer:

Pedro made 54 ounces of coffee in total.

Step-by-step explanation:

Identify what you know:

1) Pedro gave his friend 34 ounces of coffee.

2) There was 20 ounces of coffee left over after!

So, we need to add the amount of coffee that his friend had, to the amount that's left, to get the total amount that he made.

Let's make an equation, where x equals the total amount!

34 + 20 = x

OR

x - 34 - 20 = 0

Hope this helps!

Answer:

54

Step-by-step explanation:

34+20= 54 ounces of coffee

Given:

A right angle triangle ABC, right angled at C.

To find:

The measure of θ.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

In triangle ABC,

[tex]\tan \theta=\dfrac{AC}{BC}[/tex]

[tex]\tan \theta=\dfrac{2.7}{5}[/tex]

[tex]\tan \theta=0.54[/tex]

It can be written as

[tex]\theta=\tan^{-1}0.54[/tex]

[tex]\theta\approx 28.369[/tex]

Therefore, the measure of θ is 28.369.

Answer:

the area of square is 2^(8/9) sq. inches.

Step-by-step explanation:

Answer:

Unable to be determined.

Step-by-step explanation:

AA postulate : 2 corresponding angles that are congruent.

SSS theorem : 3 sides of a triangle that are equal to another triangle's 3 sides.

SAS postulate: 2 sides and their included angle are congruent to another triangle's 2 sides and their included angle.

This would seem to follow the SAS postulate at first, but the angle we are provided is not the included angle of the sides. In triangle ABC, we are analyzing lines AB and AC. Their included angle is A, but we are given the measure for angle B.

Same with DEF; we analyze DE and DF, who share angle A, but we are given angle E as a measure.

Therefore, we cannot determine if the triangles are similar or not.
