Answers
Answer:
3/4
Step-by-step explanation:
The value of cos C x sin A is 3/2.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
AB = 1
AC = 2
BC = √3
Now,
∠B = 90°
∠A = 60°
∠C = 180 - (90 + 60) = 180 - 150 = 30°
cos C = cos 30° = √3 / 2
sin A = sin 60° = √3/2
Now,
Cos C x Sin A
= √3/2 x √3 / 2
= 3/2
Thus,
The value is 3/2.

Answers
Answer:
x : z = 8 : 25Step-by-step explanation:
Given
x : y = 2 : 5, y is 80% of zRearranging the ratios:
x/y = 2/5 ⇒ x/y = 0.4 ⇒ y = x/0.4 ⇒ y = 2.5xy is 80% of z ⇒ y = 0.8zComparing the values of y:

Write the slope- intercept form of the equation of the line described through (4,5) parallel to y= 1/4x-4
Answers
Answer:
y = 1/4 x + 4
Step-by-step explanation:
1. Because the new equation is parallel to y= 1/4x - 4 => the slope is still the same => New equation : y = 1/4x + b ( b is a number that we'll find now)
2. Put x = 4 and y = 5 in the new equation
=> 5 = (1/4)(4) + b
=> b = 4
3. So then we'll have the new equation that is parallel to y = 1/4x-4

The price of the 3.25 lb peaches is $22.75.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Bob paid $5.60 for 0.8 lb of fresh peaches. The price of the 3.25 lb peaches will be calculated as,
0.8 lb of peaches ⇒ $5.60
1 lb of peach ⇒ $5.60 / 0.8
3.25 lb of peaches ⇒ (3.25 x $5.60 ) / 0.8
3.25 lb of peaches ⇒ $22.75
Therefore, the price of the 3.25 lb peaches is $22.75.
