Answers

Answer:

X = 60°

Step-by-step explanation:

the angle you are looking for is a corresponding angle to the angle given (121°)

2x + 1 = 121

121 - 1 = 2x

121 - 1 = 120

2x = 120

120/2 = 60

X = 60

Jimmy runs 8 meters per second. His little brother runs 3 meters per second so is given a 40 meter head start. How long will it take Jimmy to catch his little brother? How far into the race will this be?

Answers

Answer:

8 Seconds

Step-by-step explanation:

Since Jimmy runs 8 meters per second, we can multiply 8x8 to find where he will be after 8 seconds.

8x8 = 64

Since Jimmy's little brother runs 3 meters per second, we can multiply 3x8 to find where he will be after 8 seconds.

3x8 = 24

But, remember, Jimmy's little brother had a 40 meter head start. So we have to add 40 to his total.

24+40 = 64

Since Jimmy and his little brother's totals are both the same, Jimmy will catch up to his little brother after 8 seconds.

An athlete eats 55 grams of protein per day while training. How much is this in milligrams?

Answers

Answer:

55,000 milligrams

Step-by-step explanation:

........

Answer:

55,000 milligrams (mg) is equal to 55 grams (g)

Step-by-step explanation:

(55 g/1 )* (1000 mg/1 g)

Multiply the top to get 55,000 and the bottom to get 1.

55,000/1

The gram units cancel out, leaving you with milligrams.

x + y = 3
x^2 + y^2 = 5
Solve

Answers

Answer:

(1, 2 ), (2, 1 )

Step-by-step explanation:

Given the 2 equations

x + y = 3 → (1)

x² + y² = 5 → (2)

Rearrange (1) expressing y in terms of x by subtracting x from both sides

y = 3 - x → (3)

Substitute y = 3 - x into (2)

x² + (3 - x)² = 5 ← expand and simplify left side

x² + 9 - 6x + x² = 5

2x² - 6x + 9 = 5 ( subtract 5 from both sides )

2x² - 6x + 4 ( divide through by 2 )

x² - 3x + 2 = 0 ← in standard form

(x - 1)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 2 = 0 ⇒ x = 2

Substitute these values into (3) for corresponding values of y

x = 1 : y = 3 - 1 = 2 ⇒ (1, 2 )

x = 2 : y = 3 - 2 = 1 ⇒ (2, 1 )

On a blueprint, the diagram of a building has a height of 25 cm.
The height of the building is x times the height of the diagram.
Which equation represents the height, h, of the building?
h = 25 : x
B
x = 25h
h = 25 + x
h = 25x

Answers

Answer:

h = 25x

Step-by-step explanation:

Given the following

height of building = h

height of diagram = 25cm

If the height of the building is x times the height of the diagram, then;

h = x * 25

h = 25x

Hence the required equation is h = 25x

Step-by-step explanation:

The area of a parallelogram is base * height, so you have to find the height.

You can see on the left there's a 30 - 60 - 90 triangle with a hypotenuse of 4. Using the proportion rule, you know that the 2nd side is 4/[tex]\sqrt{3}[/tex] = [tex]4\sqrt{3}/3[/tex].

Then, find the area, so do base * height = 5 * [tex]4\sqrt{3} /3[/tex] = [tex]20\sqrt{3}/3[/tex].

Put this in a calculator and you get: 11.5 m^2

E is the midpoint of ,

ACBD,

As given E is the midpoint of the line [tex]\overline{BD}[/tex],

So, BE = ED,

further, line AE = AE, because this is the common line between the two triangles.

Also, ∠BED =∠DEA =90°, as AC⊥ BD.

3. Find the surface area for the given cylinder. Use 3.14 for r and round to the nearest whole number. (1 point)
A. 904
B.1,017
C.1,130
D.2,713​

Answers

Answer:

C

Step-by-step explanation:

The surface area of a cylinder is given by the formula:

[tex]SA=2\pi rh+2\pi r^2[/tex]

Where h is the height and r is the radius of the cylinder.

The given radius is 6 and the height is 24.

We are also using 3.14 for π.

Therefore;

[tex]SA\approx 2(3.14)(6)(24)+2(3.14)(6)^2[/tex]

Evaluate:

[tex]SA\approx1130.4\approx 1130[/tex]

The answer is C.

A rock is thrown down from a cliff that is 180 m high. The function
h(t) = -5t^2 – 10t + 180 gives the approximate height of the rock
above the water, where h(t) is the height in metres and t is the time
in seconds. When will the rock reach a ledge that is 105 m above
the water?

Answers

Answer:

t = 3

Step-by-step explanation:

105 = -5t^2 -10t + 180

-75 = -5t^2 -10t

15 = t^2 +2t

t^2 +2t -15 = 0

(t+5)(t-3)

t = -5, 3

There's no such thing as negative time so you use the positive answer

Kellie is purchasing the package of dog food shown (dog kibble 7pounds) how many 8 ounce servings can she feed her dog

Answers

Answer:

14 servings

Step-by-step explanation:

Step 1

We convert 7 pounds to ounces

0.0625 pound = 1 ounce

7 pounds = x

Cross Multiply

0.0625x = 7

x = 7/0.0625

x = 112 ounces

Step 2

The number of 8 ounce servings she can give to her dog is calculated as:

8 ounces = 1 serving

112 ounces = x servings

Cross Multiply

8 × x = 112 × 1

8x = 112

x = 112/8

x = 14 servings

Therefore, the number of 8 ounce servings she can feed her dog is 14
