Answer:

A 48 degrees B 88 degrees C 44 degrees

Step-by-step explanation:

All the sides of a triangle add up to 180 degrees.

Subtract the known side from 180. 180-48=132 degrees. That means 132 degrees is the total size of the unknown two angles. You can write that like this:

132=x+(x-44)

Simplify

132=2x-44

add 44

176=2x

Divide by 2

x = 88 degrees.

Now we know that angle B is 88 degrees. Now we just have to find angle C, which will be simple now that we know what x equals.

X-44

88-44

44 degrees

explanation:

5+(3×n)=5

5 + 3n = 5

3n = 5 - 5

3n = 0

n = 0

check:

5+(3×0) = 5

5 + 0 = 5

5 = 5

Both sides equal, therefore statement true.

Answer:

225 units squared

Step-by-step explanation:

The area of a triangle is 1/2*base*height.

A = 1/2*b*h

base = 45

height = 10

Just plug into formula.

A = 1/2*(45)*(10) = 225

Answer:

Step-by-step explanation:

Relationship Equation between time and shrimps cleaned : S = 4T; Relationship is inversely proportional; Unit rate of change = 4

Given : 4 Shrimps cleaned every minute.

So, Shrimps cleaned 'S' = 4 times minutes taken 'T' ; S = 4T

The relationship between variables is proportional, as the dependent variable (shrimps) is constant multiples times the independent variable (time), & their ratio remains constant.

It is directly proportional, as both variables (shrimps & time)  move in same direction. One variable increase or decrease, other variable same respectively.

Graph in this case is upward sloping curve from origin, because of  direct proportional relationship respectively.

Unit rate of change denotes constant magnitude of change in a variable with other variable. It is 4 in this case, as time increases the shrimps.

Answer:

55°

Step-by-step explanation:

[tex]m\angle X = m\angle Z[/tex] (Opposite angles of a parallelogram)

[tex]\implies m\angle X = 70\degree[/tex]

In [tex]\triangle WXY[/tex]

WX = XY (given)

[tex]\implies m\angle XWY = m\angle XYW[/tex]

(Angles opposite to equal sides are equal)

[tex]m\angle XWY = x [/tex] (Given)

[tex]\implies m\angle XYW=x[/tex]

[tex]\implies x + x + 70\degree=180\degree[/tex]

(By angle sum postulate of a triangle)

[tex]\implies 2x =180\degree-70\degree[/tex]

[tex]\implies 2x= 110\degree[/tex]

[tex]\implies x= \frac{110\degree}{2}[/tex]

[tex]\implies\huge{\orange {\boxed{ x=55\degree}}}[/tex]

A total of 72 containers need to be set up. If 39 are already placed then there are 33 left. You multiple the number of rows by the number of containers per row to find your total and subtract what has already been done.

The length of CD is the number of units on segment CD

Using the assumed parameters, the length of segment CD is 3 units

The question is incomplete, as the length of segment CD cannot be explicitly calculated from the given parameters.

Using a general explanation, a possible way to calculate the length of segment CD is if triangles EFG and CDE are similar triangles where segment CD and EF are similar sides.

So, we have:

CD = k * EF

Where k is the scale factor.

Assume the scale factor is 1/3, the equation becomes

CD = 1/3 * 9

CD =3

Using the assumed parameters, the length of segment CD is 3 units

Answer:

D

Step-by-step explanation:

36x² - 49 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

then

36x² - 49

= (6x)² - 7²

= (6x - 7)(6x + 7)

Thus 6x - 7 is a factor of the expression

We need to simplify the expression 36x² - 49 , but let's recall the identity which is the main key to solve this question i.e

So , here we can write the above expression as

[tex]{:\implies \quad \sf (6x)^{2}-(7)^{2}}[/tex]

Now , using the above identity this can be written as :

[tex]{:\implies \quad \sf (6x-7)(6x+7)}[/tex]

So , here both (6x-7) and (6x+7) are factors of 36x²- 49 , but in the options their is only 6x - 7.

Hence , Option D) 6x - 7 is correct

As here , 36x² = (6x)² = a² , so a = 6x and as 49² = 7² = b² , so b = 7

Answer:

852

Step-by-step explanation:

2 times 10 is 20

8 times 109 is 872

You subtract the two values, 872-20=852

If Florida has a population of about 2 X 10'. The Earth has a population of about 8 X 109. Then 852  times more populated is the Earth than Florida.

Two or more expressions with an Equal sign is called as Equation.

Given that

Florida has a population of about 2 X 10'.

The Earth has a population of about 8 X 109.

We need to find  how many times more populated is the Earth than Florida.

We know that

2 times 10 is 20

and  8 times 109 is 872

To calculate how many times more populated is the Earth than Florida. we just required to subtract 872 and 20.

You subtract the two values, 872-20=852

Hence About 852 times more populated is the Earth than Florida.
