10. The sum of a certain number and a second number is -42. The first
number minus the second number is 52. Find the numbers.
56​

Answers

Answer:

the first number and the second number is 5 and -47 respectively

Step-by-step explanation:

Let us assume the first number be x

And, the second number be y

According to the question

x + y = -42

x - y = 52

x = 52 + y

Now put the value of x in the first equation  i.e.

x + y = -42

52 + y + y = -42

2y = -42 - 52

2y = -94

y = -47

And, x is

x + y = -42

x -47 = -42

x = 5

Hence, the first number and the second number is 5 and -47 respectively

graphic card?
a. X+0.085x
b. X- 0.085x
c. X+0.085
d. X-0.085


38 points!! Will give crown

Answers

Answer:

x + 0.085x

Step-by-step explanation:

Because.. in the last sentence it says the total cost which means add so then you eliminate b and d...so after that before 8.5% it says sales tax...so then that is when you add a x at the end. so it is........x+0.085x.

John wants to measure the height of a tree. His eye level is 6 feet from the ground. He walks exactly 100 ft from the base of
the tree and looks up. The angle from the Johns eye level to the top of the tree is 33º. How tall is the tree?

Answers

Answer:

70.9 feets

Step-by-step explanation:

From trigonometry:

tan θ = opposite /Adjacent

Opposite = tree height, y

Adjacent = vertical distance between eyelevel and tree

tan 33º = y/100

y = 100 * tan 33º

y = 100 * 0.6494075

y = 64.9 feets

Distance between John's eye level and the ground = 6 feets

Total tree height = 6 + 64.9 = 70.9 feets

Answer:

Area of the circle = 616[tex]cm^{2}[/tex]

Volume of the rectangular prism = 416[tex]mm^{3}[/tex]

Step-by-step explanation:

Area of a circle = [tex]\frac{22}{7}r^{2}[/tex] where, r is the radius.

To find the radius, take the half of diameter

[tex]\frac{28}{2} =[/tex] 14

= [tex]\frac{22}{7}[/tex][tex]14^{2}[/tex]

= [tex]\frac{22}{7}[/tex] × 196

= 22 × 28

= 616[tex]cm^{2}[/tex]

Volume of a rectangular prism = length × breadth × height

= 10.4 × 5 × 8
