Trust me on this one
Answer:
x = 1
Step-by-step explanation:
Let's do this quickly and easily,
30 = 5(x + 5)
30 = 5x + 25
5x = 30 - 25
x = 5/5
x = 1

Answer:
A
Step-by-step explanation:
Using the sine ratio on the right triangle on the right to find x
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{70}[/tex] ( multiply both sides by 70 )
70 × sin30° = x , thus
x = 35
-----------------------------------------------
Using the sine ratio on the right triangle on the left to find y
sin42° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{y}[/tex] = [tex]\frac{35}{y}[/tex] ( multiply both sides by y )
y × sin42° = 35 ( divide both sides by sin42° )
y = [tex]\frac{35}{sin42}[/tex] ≈ 52.3 ( to the nearest tenth ) → A
Answer:
y = 52.3.
Step-by-step explanation:
Consider the larger triangle on the right:
sin 30 = x / 70
x = 70 sin 30 = 70 * 0.5
= 35.
So, considering the small triangle:
Sin 42 = 35/y
y * sin 42 = 35
y = 35 / sin 42
y = 52.3.

the length of a rectangle is 5 M more than twice its width find the area of the rectangle if it's perimeter is 20 m
The area of the rectangle is [tex]\frac{125}{9}m^{2}[/tex]
Given that the length of a rectangle is 5m more than twice its width and the perimeter of the rectangle is 20m
length of rectangle(l)=5m+2(width of rectangle)(w)
l=5+2w
The perimeter of rectangle=2(length of rectangle+width of rectangle)
Perimeter of rectangle=2(5+2w+w)
The perimeter of the rectangle=2(5+3w)
20=2(5+3w)
10=5+3w
5=3w
w=[tex]\frac{5}{3}[/tex]
l=5+2w
⇒l=5+[tex]\frac{10}{3}[/tex]
⇒l=[tex]\frac{25}{3}[/tex]
Area of rectangle =(length of rectangle)×(width of rectangle)
Area of rectangle =[tex]\frac{25}{3}[/tex]×[tex]\frac{5}{3}[/tex]
Area of rectangle = [tex]\frac{125}{9}m^{2}[/tex]
Therefore, The area of the rectangle is [tex]\frac{125}{9}m^{2}[/tex]

A recipe requires 1 2/3 cups of sugar. If Mrs.Marina is going to make one and one half of the recipe, then how much sugar does she need
Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.
What is proportion ?
A proportion is an equation based on the equality of two ratios.
Here it is given that :
A recipe requires 1 (2/3) cups of sugar.
That is 1 recipe requires = 1(2/3) cups of sugars
= 5/3 cups of sugar
Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :
1 recipe requires = 5/3 cups of sugar
1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar
3/2 recipe requires = (5/3) x (3/2) cups of sugar
3/2 recipe requires = 5/2 cups of sugar or 2.5 cups of sugar.
Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.

Step-by-step explanation:
Consider the line y=6×-7
what is the slope of a line parallel to this line?
what is the slope of a line perpendicular to this line?
Answer:
The slope of a line parallel to this line will be: 6
The slope of the perpendicular line will be: -1/6
Step-by-step explanation:
We know the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope b is the y-interceptGiven the equation
[tex]y=6x-7[/tex]
Thus, the slope of the line is: 6
The slope of a line parallel to the line:
We have already determined that the slope of the line is: 6
We know that the parallel lines have the same slope.Thus, the slope of a line parallel to this line will be: 6
The slope of a line perpendicular to the line:
We have already determined that the slope of the line is: 6
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
Thus, the slope of the perpendicular line will be:
[tex]\frac{-1}{6}\:\:[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]=-\frac{1}{6}[/tex]
Therefore, the slope of the perpendicular line will be: -1/6

10. What is the measure of angle C?
A. 25°
B. 30°
C. 60°
D. 75°
Answer:
D
Step-by-step explanation:
x + 5 + 3x + C = 180 All triangles have 180 degrees.
4x + 5 + C = 180
But C must be equal to 3x. Notice the markings on the lets of the triangle.
4x + 5 + 3x = 180
7x + 5 = 180 Subtract 5 from both sides
7x = 180 - 5
7x = 175
x = 25
But angle C = 3x
C = 3*25
C = 75
