Ana’s gymnastics scores were posted on the scoreboard in order from highest to lowest score. One digit in her floor score is not

BabaBlast [244]

Answers :a) digits are 1, 2, 3, 4 , b) difference is 0.367

Step-by-step explanation:

The floor score must be higher than 15.133 and lower than 15.500

The missing digit must be an integer.

Then all the possible scores are: 15.166 , 15.266 , 15.366 and 15.466

Then all the possible digits are 1 , 2 , 3 and 4

The difference between her vault score and her uneven bar score is

15.500 - 15.133 = 0.367

Answers :a) digits are 1, 2, 3, 4 , b) difference is 0.367

Solve for r v = 4/3 r^3

sergejj [24]

Answer:

$r=\sqrt[3]{\frac{3v}{4} }$

Step-by-step explanation:

To solve for $r$ :

$v=\frac{4}{3}r^{3}$ (given)

$\frac{3v}{4}=r^{3}$ (times $\frac{3}{4}$ on both sides)

$r=\sqrt[3]{\frac{3v}{4} }$

I hope this helps :)

An AISI 1040 cold-drawn steel tube has an OD 5 50 mm and wall thickness 6 mm. What maximum external pressure can this tube withs

lukranit [14]

Answer:

82.79MPa

Step-by-step explanation:

Minimum yield strength for AISI 1040 cold drawn steel as obtained from literature, Sᵧ = 490 MPa

Given, outer radius, r₀ = 25mm = 0.025m, thickness = 6mm = 0.006m, internal radius, rᵢ = 19mm = 0.019m,

Largest allowable stress = 0.8(-490) = -392 MPa (minus sign because of compressive nature of the stress)

The tangential stress, σₜ = - ((r₀²p₀)/(r₀² - rᵢ²))(1 + (rᵢ²/r²))

But the maximum tangential stress will occur on the internal diameter of the tube, where r = rᵢ

σₜₘₐₓ = -2(r₀²p₀)/(r₀² - rᵢ²)

p₀ = - σₜₘₐₓ(r₀² - rᵢ²)/2(r₀²) = -392(0.025² - 0.019²)/2(0.025²) = 82.79 MPa.

Hope this helps!!

(1,-7) with a slope of -5 as an equation

Liono4ka [1.6K]

Answer:

y=-5x-2

Step-by-step explanation:

y=mx+b

where m is the slope

y=-5x+b

to solve for b, which is the y intercept, plug in (1,-7)

-7=-5(1)+b

-7=-5+b

-2=b

y=-5x-2
