Answer:
x = -1/3
Step-by-step explanation:
We have,
sin(x + 7) = cos(4x + 8)
We need to find the value of x.
We know that,
sin(90-x) = cosx
So,
sin(90-(x + 7)) = cos(4x + 8)
cos(x+7) = cos(4x + 8)
i.e.
(X+7) = (4x+8)
7-8 = 4x-x
-1 = 3x
x = -1/3
Answer:
sin(22 ∘ ) = cos(68∘ )
Step-by-step explanation:
Sin(x+7)=cos(4x+8)
(x+7) + (4x+8) = 90
x + 7 + 4x + 8 = 90
5x + 15 = 90
−15 = −15
5x/5 = 75/5
x = 15
Answer: sin(22 ∘ ) = cos(68∘ )

In the following diagram, parallelogram ABCD contains triangle CED. Line CE and line ED intersect at point E. The measures of ∠CEA and ∠CDE are shown. What is the measure of x?______ degrees *
Answer:
∠x = 59°
Step-by-step explanation:
∠ECD = 52° because they are alternate angles and will be equal
∠x = 180° - 52° - 69° = 59° because the sum of the interior angles of a triangle = 180°

equations models the situation, where a is the number of adult tickets purchased and s is the number of student tickets purchased. Write the
terms with the variables in alphabetical order.
9a + 5.5s = 1.105

A rectangular window is 3.5 feet wide and has an area of 19.25 square ft you have six yards of string light do you have enough string lights to outline the window with light
Answer:
yes
Step-by-step explanation:
We are to determine if 6 yards is enough t to go round the perimeter of the window
The length is not given, so we have to determine the length from the area
Area of a rectangle = length x breadth
19.25 = 3.5 x length
length = 5.5 feet
Perimeter = 2 x ( length + breadth )
2 x (5.5 + 3.5) = 18 feet
We need to convert the string to foot
1 yard = 3 foot
6 x 3 = 18 foot
the string and the perimeter are equal, so it is enough

Solve for x, y, and z. Enter the integer that is under each radical.
Answer:
[tex] x=\sqrt{10} [/tex]
[tex] y = \sqrt {14} [/tex]
[tex] z = \sqrt {35} [/tex]
Step-by-step explanation:
By geometric mean theorem:
[tex] x=\sqrt{2\times 5} [/tex]
[tex] x=\sqrt{10} [/tex]
By Pythagoras Theorem:
[tex] y^2 = x^2 + 2^2 [/tex]
[tex] y^2 = (\sqrt{10}) ^2 + 2^2 [/tex]
[tex] y^2 = 10 + 4 [/tex]
[tex] y^2 = 14 [/tex]
[tex] y = \sqrt {14} [/tex]
Again by Pythagoras Theorem:
[tex] z^2 = x^2 + 5^2 [/tex]
[tex] z^2 = (\sqrt{10}) ^2 + 5^2 [/tex]
[tex] z^2 = 10 + 25 [/tex]
[tex] z^2 = 35 [/tex]
[tex] z = \sqrt {35} [/tex]
What is the slope of the line through (-7,-2) and (−6,7)?
Answer:
slope = 9
Step-by-step explanation:
To find the slope of a line that passes through a pair of points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (-7,-2) and (-6,7) into the formula and simplify:
[tex]m = \frac{(7)-(-2)}{(-6)-(-7)} \\m = \frac{7+2}{-6+7} \\m = \frac{9}{1} \\m = 9[/tex]
So, the slope is 9.
Regan cycles 78 miles in 6 hours. His average speed for the first 30 miles is 15 miles per hour. Work out Regan's average speed for the last 48 miles.
Answer:
12 mph
Step-by-step explanation:
Given that:
Total distance traveled = 78 miles
Time taken, t = 6 hours
Average speed for first 30 miles = 15 mph
Time taken = distance / speed
Time taken = 30 / 15
Time taken = 2 hours
Average speed for last 48 miles = x
Time taken to travel last 48 miles = (6 - 2) = 4 hours
Average speed for last 48 miles :
Distance traveled / time taken
48 miles / 4 hours
= 12 mph

The owner of a tree farm plants pine trees and oak trees in a ratio of 8:3. How many oak trees are planted if 264 pine trees are planted
Answer:
99 oak trees
Step-by-step explanation:
Given data
Ratio= 8:3
Number of pine tree= 264
Let the number of oak trees be x
Let us apply the part to part method
8/264= 3/x
cross multiply
264*3= 8x
792=8x
x= 792/8
x=99 oak trees
The owner of the tree farm planted 99 oak trees.
An equation is an expression used to show the relationship between two or more numbers or variables.
Given that a farmer plants pine trees and oak trees in a ratio of 8:3. If 264 pine trees are planted, let y represent the total number of trees hence:
264 = (8/11) * y
y = 363 trees
Number of oak trees = (3/11) * 363 = 99 trees
Therefore the owner of the tree farm planted 99 oak trees.
