Answer:

EF = 8.8 cm

Step-by-step explanation:

In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;

[tex]/hyp/^{2}[/tex] = [tex]/adj1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]

[tex]/DE/^{2}[/tex] = [tex]/EF/^{2}[/tex] + [tex]/DF/^{2}[/tex]

[tex]/16.2/^{2}[/tex] = [tex]/EF/^{2}[/tex] + [tex]/13.6/^{2}[/tex]

262.44 = [tex]/EF/^{2}[/tex] + 184.96

[tex]/EF/^{2}[/tex] = 262.44 - 184.96

          = 77.48

EF = [tex]\sqrt{77.48}[/tex]

     = 8.8023

EF = 8.8 cm

The length of side EF is 8.8 cm.

Answer:

We conclude that

[tex]4\frac{2}{3}[/tex]    >   [tex]\sqrt{21}[/tex]

Step-by-step explanation:

Given

as

[tex]\:\sqrt{21}=4.58[/tex]

and

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

Convert mixed numbers to improper fraction:

[tex]a\frac{b}{c}=\frac{a\cdot \:c+b}{c}[/tex]

so

[tex]4\frac{2}{3}=\frac{4\cdot 3+2}{3}=\frac{14}{3}=4.67[/tex]

Thus,

[tex]\:\sqrt{21}=4.58[/tex]

[tex]4\frac{2}{3}=4.67[/tex]

as

4.67      >       4.58

so

[tex]4\frac{2}{3}[/tex]         >        [tex]\sqrt{21}[/tex]

Hence, we conclude that

[tex]4\frac{2}{3}[/tex]    >   [tex]\sqrt{21}[/tex]

Answer:

  30°

Step-by-step explanation:

The angle a line makes with the x-axis is arctan(slope). Here, that is ...

  angle with x-axis = arctan(√3) = 60°

So, the angle made with the y-axis is the complement of this:

  angle with y-axis = 90° -60° = 30°

Answer:

m∠B = 170°

Step-by-step explanation:

Sum of all angles in quadrilateral is 360°:

m∠A + m∠B + m∠C + m∠D = 360°

m∠B = 360° - m∠A - m∠C - m∠D

m∠A = 90°

m∠B = m∠D= 50°

m∠B =  360° - 90° - 50° - 50° = 170°

Answer:

1.5

Step-by-step explanation:

When we divide two fractions, such as 3/4 ÷ 1/2, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

We also simplify the answers to fraction problems whenever possible.

Answer: 3/2 or 1 and 1/2

Step-by-step explanation: Remember that dividing by a fraction

is the same thing as multiplying by the reciprocal of the fraction.

The reciprocal of a fraction is just that fraction flipped.

So 3/4 ÷ 1/2 can be rewritten as 3/4 × 2/1.

Before multiplying however, notice that we

can cross-cancel the 2 and 4 to get 1 and 2.

Finally, multiplying across the numerators and

across the denominators, we have 3/2 or 1 and 1/2.

Answer:

y=93°, z=79°

Step-by-step explanation:

Lines and Angles

There are properties of lines and angles that will help us to find the required values.

The vertex at the bottom left side of the quadrilateral has two angles that were formed when two lines crossed. Those are called linear angles, and they always add up to 180°.

This means that z is the angle needed to complete 180°, that is:

z = 180° - 101° = 79°

Now the quadrilateral must have the sum of its internal angles equal to 360°. We have three of them that sum: 100°+88°+79°=267°.

This means y is the angle needed to complete 360°, or:

y = 360° - 267° = 93°

Answer: y=93°, z=79°

Answer:

(x, y)  -->   (x + 14, y + 8)

Step-by-step explanation:

Look at 1 original point and its corresponding translated point.

Let's look at F and F'.

To go from F to F', you need to go right in x 14 units.

Then you need to go up in y 8 units.

The translation rule is to add 14 to x and 8 to y.

(x, y)  -->   (x + 14, y + 8)

It just is see explanation

Step-by-step explanation:

75% is equal to 0.75, or 3/4. If you multiply the full 60 minutes to 3/4, then your product is 45 minutes. That's how 75% of 60 minutes is 45 minutes.

Answer: 75% of a number is the same thing as 3/4 of the number.

so for example, divide 100 by 4. you get 25 right?

right, so multiply 25 by 3 and you get 75. That's what 3/4 of something is.

now divide 60 by 4. you get 15 right?

right, so multiply 15 by 3, and you get 45 :)))

that's why 75% of 60 is 45.

i hope this helps!!

BTW when you get a question with percentages, you can flip them! In this case it doesn't really help to do so, but for example if you had a question asking:

what is 16% of 50?

FLIP IT. it's the same thing as 50% of 16!!!  This works with like any percentage!!!

Answer:

10% would be 6

Step-by-step explanation:

First you want to find the 100 percent amount  to turn 40 into 100 you need to multiply it by 2.5 so you want to take 24 and multiply by 2.5 which equal 60 and 60 divided by 10  is 6

Answer:

x = 4.99°

Step-by-step explanation:

Reference angle = x

Opposite side to x = 20 cm

Hypotenuse = 230 cm

Applying trigonometric ratio formula, we would have the following equation:

[tex] sin(x) = \frac{Opp}{Hyp} [/tex]

Plug in the values

[tex] sin(x) = \frac{20}{230} [/tex]

[tex] x = sin^{-1}(\frac{20}{230}) [/tex]

x = 4.99° (approximated to nearest hundredth)
