Answer:
[tex]\frac{\sqrt{5}}{\sqrt{8}}=\frac{1}{4}\sqrt{10[/tex]
Step-by-step explanation:
Given
[tex]\frac{\sqrt{5}}{\sqrt{8}}[/tex]
Required
Express in its simplest form
To do this, we simply radicalize the given expression by multiplying the expression by the denominator over the denominator.
In other words:
[tex]\frac{\sqrt{5}}{\sqrt{8}} * \frac{\sqrt{8}}{\sqrt{8}}[/tex]
[tex]\frac{\sqrt{5}*\sqrt{8}}{\sqrt{8}*\sqrt{8}}[/tex]
[tex]\frac{\sqrt{40}}{\sqrt{64}}[/tex]
Take positive square root
[tex]\frac{\sqrt{40}}{8}[/tex]
Express 40 as 4 * 10
[tex]\frac{\sqrt{4*10}}{8}[/tex]
[tex]\frac{\sqrt{4}*\sqrt{10}}{8}[/tex]
[tex]\frac{2*\sqrt{10}}{8}[/tex]
Simplify:
[tex]\frac{1*\sqrt{10}}{4}[/tex]
[tex]=\frac{1}{4}\sqrt{10[/tex]
Hence:
[tex]\frac{\sqrt{5}}{\sqrt{8}}=\frac{1}{4}\sqrt{10[/tex]

An angle measures 20° less than the measure of its complementary angle. What is the measure of each angle
Answer:
The angle measure is 35°.
Step-by-step explanation:
Complementary angles in geometry are angles that summate to exactly 90 degrees. If an angle measures 20 degrees less than the measure of its complementary angle, we can create an equation to find the measure of this angle.
The complementary angle is going to equal 90 - x, so this becomes a term in our equation: (90 - x)
Both angles need to add up to 90 degrees, so we can set up this equation:
x = (90 - x) - 20, where x is our unknown angle.
Now, we can just solve for x.
[tex]x = (90-x)-20\\\\x = 90 - x - 20\\\\x = 70 - x \\\\2x = 70\\\\\bold{x = 35}[/tex]
Therefore, the angle that measures 20 degrees less than its complementary angle is 35°. We can check this by using substitution:
[tex]90 = x + 35\\\\55 = x \rightarrow x = 55\\\\55 - 35 = 20[/tex]
Therefore, the two angles are 55° and 35°, but the angle that measures 20° less than the measure of its complementary angle is 35°.

List 3 rational numbers between -5/13 and 1/13
Plz help
Answer:
[tex]\displaystyle -\frac{4}{13},~-\frac{3}{13},~-\frac{1}{13},~0[/tex]
Step-by-step explanation:
Rational Numbers
The rational numbers are defined as numbers of the form [tex]\frac{a}{b}[/tex] where a and b are integer numbers and b is not zero.
Two rational numbers expressed as fractions can be better compared if they have the same denominator. For example, 5/11 is greater than 3/11 because they have the same denominator and 5 is greater than 3.
Similarly, if we have the fractions -5/13 and 1/13, it's clear that the first fraction is less than the second. If we wanted to have some rational numbers between them we only have to play around with the numerators: any number between -5 and 1 will do.
Examples of the required numbers:
[tex]\displaystyle -\frac{4}{13},~-\frac{3}{13},~-\frac{1}{13},~0[/tex]

We know that given triangles are congruent. When two triangles are congruent then their respective sides are also equal/congruent.
So,
ΔUWV≅ΔEDF
Then

So,
Putting their respective value equal:
WV = DF

A communications tower is supported by two wires, connected at the same point on the ground. One is attached to the tower at D and the long-on at C. The angle AD makes with the ground is 30 ° and the angle between the two wires is 10 °. How much below the top of the tower is the shorter one attached?
Answer:
10.99 m
Step-by-step explanation:
✍️What we are basically asked to solve here is to find the distance between C and D.
To find CD, find the length of BC, and BD. Their difference will give us CD.
Thus, BC - BD = CD.
✍️Finding BC using trigonometric ratio formula:
[tex] \theta = 30 + 10 = 40 [/tex]
Opposite side = BC = ??
Adjacent side = 42 m
Thus:
[tex] tan(\theta) = \frac{opposite}{adjacent} [/tex]
Plug in the values
[tex] tan(40) = \frac{BC}{42} [/tex]
Multiply both sides by 42
[tex] tan(40) \times 42 = \frac{BC}{42} \times 42 [/tex]
[tex] 35.24 = BC [/tex]
BC = 35.24 m
✍️Finding BD using trigonometric ratio formula:
[tex] \theta = 30 [/tex]
Opposite side = BD = ??
Adjacent side = 42 m
Thus:
[tex] tan(\theta) = \frac{opposite}{adjacent} [/tex]
Plug in the values
[tex] tan(30) = \frac{BD}{42} [/tex]
Multiply both sides by 42
[tex] tan(30) \times 42 = \frac{BD}{42} \times 42 [/tex]
[tex] 24.25 = BD [/tex]
BD = 24.25 m
✍️How much below the top of the tower is the shorter one attached:
Thus,
BC - BD = CD
35.24 m - 24.25 m = 10.99 m

Why it said he used partial products to write 7 × 870 = 5600 + 49 explain why its error in use math to justify your explanation
The person is wrong because instead of writing the product as 5600 + 49 he must write 5600 + 490.
The given equation is 7 × 870 = 5600 + 49.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
Now, product of two numbers 7 and 870 is
7 × 870=6090
⇒ 7 × 870 = 5600 + 490
Hence, the person is wrong because instead of writing the product as 5600 + 49 he must write 5600 + 490.

9. The temperature outside Jeff's house is 14 °C at midday.
By midnight, the temperature has fallen by 27 °C.
What is the temperature at midnight?

Step-by-step explanation:
The temperature has fallen, so you subtract.
14ºC-27ºC=-13ºCCoordinates of Z if Y is the midpoint of XZ, X(10,9) and Y(-4,8)
Answer:
[tex]Z(x,y) = (-18,7)[/tex]
Step-by-step explanation:
Given
[tex]X = (10,9)[/tex]
[tex]Y = (-4,8)[/tex]
Required
Determine the coordinates of Z
From the question, we understand that Y is the midpoint
And the midpoint is calculated as:
[tex](x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
In this case:
[tex]Y(x,y) = (-4,8)[/tex]
[tex]X(x_1,y_1) = (10,9)[/tex]
[tex]Z = (x_2,y_2)[/tex]
So: This gives
[tex](x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
[tex](-4,8) = (\frac{10+x_2}{2},\frac{9+y_2}{2})[/tex]
Multiply through by 2
[tex](-8,16) = (10 + x_2,9+y_2)[/tex]
By comparison:
[tex]-8 = 10 + x_2[/tex] and [tex]16 = 9 + y_2[/tex]
Solving for x2
[tex]-8 = 10 + x_2[/tex]
[tex]-8 - 10 = x_2[/tex]
[tex]-18 = x_2[/tex]
[tex]x_2 = -18[/tex]
Solving for y2
[tex]16 = 9 + y_2[/tex]
[tex]16 - 9 = y_2[/tex]
[tex]7 = y_2[/tex]
[tex]y_2 = 7[/tex]
Hence, the coordinates of Z is:
[tex]Z(x,y) = (-18,7)[/tex]
