Answer:

10

Step-by-step explanation:

convert mixed number into improper fraction

15/2÷3/4

to divide by a fraction multiply by the reciprocal of that fraction

15/2×4/3

reduce the numbers with the greatest common factor 3

5/2×4

reduce the numbers with the greatest common factor 2

multiply the numbers

5×2=10

10 is your answer

y intercept of the graph of  equation y = square root of 4-x is 2
Hence option c 2 is correct.

y = [tex]\sqrt{4-x}[/tex]

equation is the relationship between variable and represented as is example of polynomial equation.

at x = 0
y =  [tex]\sqrt{4-0}[/tex]
y = 2
Hence, y intercept is 2

Thus, y intercept of the graph of  equation y = square root of 4-x is 2

Answer:

perimeter of rectangle = 102.4 cm

Step-by-step explanation:

here's your solution

==> perimeter of rectangle = 2(length + width)

=> length = 40.3 cm

=> width = 10.9 cm

=> perimeter = 2(40.3 + 10.9)

=> perimeter = 2(51.2)

==> perimeter of rectangle = 102.4 cm

Answer:

Corresponding angles are equal, so 4x-18=3x-8  x=10

Step-by-step explanation:

the answer is

y≥2x/5+2

Step-by-step explanation:

we moved the y to the right site and the -10 to the left site

so we had

2x+10≤5y

and then we devided by 5

2x/5+10/5≤y

y≥2x/5+2

hopefully its correct

Answer:  Choice D

[tex]y \ge \frac{2}{5}x +2\\\\[/tex]

=======================================

Work Shown:

[tex]2x - 5y \le -10\\\\-5y \le -2x-10\\\\y \ge \frac{-2x-10}{-5} \ \text{ ... see note1 below}\\\\y \ge \frac{-2x}{-5} - \frac{10}{-5}\\\\y \ge \frac{2}{5}x +2 \ \text{ ... answer is choice D}\\\\[/tex]

Note1: when dividing both sides by a negative number, the inequality sign flips.

----------------

Here's another approach that doesn't involve dividing both sides by a negative number.

[tex]2x - 5y \le -10\\\\2x \le -10+5y\\\\2x +10\le 5y\\\\5y \ge 2x+10 \ \text{ .... see note2 below}\\\\y \ge \frac{2x+10}{5}\\\\y \ge \frac{2x}{5} + \frac{10}{5}\\\\y \ge \frac{2}{5}x +2\\\\[/tex]

Note2: I swapped the left and right sides. Doing this swap means that the inequality sign must flip as well.

Answer:

[tex]\theta=16.6^{\circ}[/tex]

Step-by-step explanation:

Given that,

The surface of the ramp will be 7 feet long with a total rise of 2 feet.

We need to find the angle of elevation of the ramp. We can use trigonometry to find it such that,

[tex]\sin\theta=\dfrac{P}{H}[/tex]

P is perpendicular

H is hypotenuse

Here, P = 2 feet, H = 7 feet

So,

[tex]\sin\theta=\dfrac{2}{7}\\\\\theta=16.6^{\circ}[/tex]

So, the angle of elevation of the ramp is equal to [tex]16.6^{\circ}[/tex].

Step-by-step explanation:

the area for grass seed = 0.75×68×40½=

2,065.5 ft²

the grass seed will the owner need to plant =

2,066.5/1,000 × 1.5 pounds = 3.1 pounds

The grass seed will the owner need to plant is 3.1 pounds.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

We are given that  rectangular backyard has a length of 68 feet and a width of 40 1/2 feet. The owner wants to plant 75% of the yard with grass seed.

The planting rate for the seed = 1.5 pounds per 1,000 square feet of area.

Then the area for grass seed

= 0.75×68×40½

= 2,065.5 ft²

Therefore, the grass seed will the owner need to plant =

2,066.5/1,000 × 1.5 pounds

= 3.1 pounds

The grass seed will the owner need to plant is 3.1 pounds.

Answer:

Area required for circular hot tube = 6,218 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of circular hot tube = 89 inches

Value of π = 3.14

Find:

Area required for circular hot tube

Computation:

Radius of hot tube = Diameter / 2

Radius of hot tube = 89 / 2 inches

Area required for circular hot tube = Area of circle

Area of circle = πr²

Area required for circular hot tube = πr²

Area required for circular hot tube = (3.14)(89/2)²

Area required for circular hot tube = (3.14)(7921 / 4)

Area required for circular hot tube = (3.14)(1,980.25)

Area required for circular hot tube = 6,217.985

Area required for circular hot tube = 6,218 inch² (Approx.)

Step-by-step explanation:

Sine equals opposite over hypotenuse, which would be y/19. To find y multiply by 19 to get y=19sin33°

Answer:

see below

Step-by-step explanation:

CD = 90 - 53 = 37°

AB = 180 - 79 - 53 = 48°

ED = 180 - 37 = 143°

EB = 180 - 53= 127°

BDE = 53 + 37 + 143 = 233°

DEC = 360 - 37 = 323°°

Answer:

∠TUV = 120°

Step-by-step explanation:

Since this figure is a kite, we know that; ∠TUV ≈ ∠TWV, so first we solve for x:

9x - 6 = 7x + 22

2x - 6 = 22

2x = 28

x = 14

Now, substitute 14 in for x, in the equation for ∠TUV:

∠TUV = 9x - 6

∠TUV = 9(14) - 6

∠TUV = 126 - 6

∠TUV = 120°

Net Earnings = $65

Step-by-step explanation:

Money deposited in saving account = $2500

Interest rate = 5% pa = 5% of 2500 = $125

Fee = $5 (monthly). So annual fee = 12 x 5 = $60

So, net earning = Interest Earning - Annual Fee

= $125 - $60 = $65
