Answer:
x = 5
Step-by-step explanation:
These triangles are similar, so they are in proportion to each other. Because of this we can say [tex]\frac{2.5}{3.5}[/tex] (the lengths of the vertical sides) = [tex]\frac{x}{7}[/tex] (the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing we get x = 5.

Answer:
y ≤ 66.28 -> -∞
Step-by-step explanation:
y = a (x-h)² + k ... (h,k): vertex
y = - 32x² + 90x + 3
= -32 (x² - (90/32)x + (90/64)²) + (3 + (32)*(90/64)²)
= -32 (x² - 2*(90/64)x + (90/64)²) + (3+63.28) ... 90/64=1.41
= -32 (x - 1.41)² + 66.28
h = 1.41
k = 66.28 .... extremum of y value
y ≤ 66.28 (y is real number)

please make me a happy with brainleist answer
The value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory option (A) is correct.
What is LIFO?Last in, first-out (LIFO) is an inventory valuation approach based on the principle that the first asset sold is the most recent asset received.
We have data shown in the table:
Total number of T-shirts = 200+300+400+300 = 1200
As there are only 400 T-shirts left it means,
So (1200-400)800 T-shirts sold out according to LIFO last month T-shirt sold out.
200 T-shirts left in the June stock
Out of 300, there are 200 T-shirts left in the month of July.
Cost for 200 T-shirts = 200×8 = $1600
Cost for 200 T-shirts = 200×10 = $2000
Total cost = 1600+2000
= $3600
Thus, the value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory.

A batter hits a baseball 4 feet above the ground with an upward velocity of 59 feet per second. The function h(t) = -16t^2 + 49t + 4 gives the height h (in feet) of the baseball after t seconds. How long is the ball in the air if a player on the other team catches the ball 7 feet above the ground?
Answers
Answer:
3 seconds
Step-by-step explanation:
when h=7 ft
-16t²+49t+4=7
-16t²+49t-3=0
16t²-49t+3=0
16t^2-48t-t+3=0
16t(t-3)-1(t-3)=0
(t-3)(16t-1)=0
t=3,t=1/16
t=1/16 seconds is the time when it just started.
so reqd. time=3 seconds.
What is the value of the expression 6 +5. (8 + 2)²?
Answers
The value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an epression:
= 6 +5. (8 + 2)²
We can solve the above expression by BODMAS:
= 6 + 5(10)²
= 6 + 5(100)
= 6 + 500
= 506
Thus, the value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.

The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel side is 20m. Find the other parallel side
Answers
Answer: 44 m
Step-by-step explanation:
Given
The area of the trapezium is [tex]A=480\ m^2[/tex]
Distance between parallel sides [tex]h=15\ m[/tex]
One of the parallel sides is [tex]20\ m[/tex]
Suppose the other parallel side is [tex]x[/tex]
The area of the trapezium is
[tex]A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h[/tex]
Put values
[tex]\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m[/tex]
