Answer:

294.1 pounds

Step-by-step explanation:

We find the z score for 90th percentile

= 1.282

Step 2

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score ??

μ is the population mean = 230 pounds

σ is the population standard deviation= 50 pounds

1.282 = x - 230/50

Cross Multiply

1.282 × 50 = x - 230

64.1 = x - 230

x = 230 + 64.1

x = 294.1 pounds

Answer:

pi or 3.14

Step-by-step explanation:

this shape is a quarter of a circle.

so, we can just find the area of the whole circle and then divide the answer by 4.

to find the area of this shape we use the formula:

pi × r^2 × 1/4

so the answer is: pi since r^2 and 1/4 cancel each other out.

Answer:

-2.6

Step-by-step explanation:

Given: 5(y+2)= -3

Do the parentheses (Multiply 5 by Y and 2): 5y+10=-3

Simplify (subtract 10 from both sides): 5y=-13

Simplify again (divide both sides by 5): y=-2.6

Double-Check:

Given (replace -2.6 for Y): 5(-2.6+2)=-3

Do the parentheses (Add-2.6 and 2): 5(-0.6)=-3

Simplify (Multiply 5 by -0.6): -3=-3 ✔️

The answer checks out.

Answer:

136

Step-by-step explanation:

Area of trapezoid:

a+b/2 * h

so,

(12/2 + 22/2) × 8

12 + 22 = 34

34/2 = 17

17 × 8 = 136

Answer:

Greatest diameter of hemisphere = 14 cm

Surface area of solid = 1330 cm²

Step-by-step explanation:

Side of the cube (a) = 14 cm

If a cube is surmounted (placed right over its top) by a hemisphere, then that means that the greatest diameter of the hemisphere will be equal to the measure of the edge of the cube (a cube has equal sides). Hence,  the greatest diameter of the hemisphere is 14 cm & the radius (r) will be 14/2  = 7 cm (radius = ½ diameter)

Now, we need to find the surface area of the solid.

Here, the solid comprises of a cube & a hemisphere sharing a same circular base area. Hence,

Surface area of the solid

= Surface area of cube + Curved surface of hemisphere - Circular base area

= 6a² + 2πr² - πr²

= 6a² + πr²

= 6(14)² + 22/7×(7)²        [π = 22/7]

= 1176 + 154

= 1330 cm²

Answer:

1. 360 km

2. 2 seconds

Step-by-step explanation:

Formula

distance = speed × time

Given:

⇒ distance = 120 × 3 = 360 km

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

Given:

To find time (t), use the SUVAT equation:  v = u + at

⇒ 20 = 0 + 10t

⇒ 20 = 10t

⇒ t = 20/10

⇒ t = 2 s

Finding the Missing Angle Within the Triangle

We know that all triangles sum to 180 degrees. So, to find the missing angle within the missing angle, we can create an equation. For the purposes of this equation, I will use y as the missing angle within the triangle.

Then, solve for y by subtracting 55 and 68 from both sides.

Finding X

The missing angle within the triangle is supplementary to the x angle. Supplementary angles are angles that sum to 180. So, to find x we can create a new equation.

Next, solve the formula by subtracting 57 from both sides.

Shortcut

In cases like this, there is a shortcut that can be used. This shortcut can be used when you are trying to find a supplementary angle outside of a triangle, and you are given the other 2 angles of triangle. The x value will always be equal to the sum of the 2 angles that are not adjacent to the missing, outside angle.

So, in this case, [tex]x=68+55[/tex] because 68 and 55 are not adjacent to the outside angle, x.

Answer:

Day 44

Step-by-step explanation:

Given function:

[tex]f(t)=500t^2[/tex]

where:

To find the day on which the number of daily hits reaches 1,000,000, set the function to 1,000,000 and solve for t:

[tex]\begin{aligned}f(t) & =1000000\\ \implies 500t^2 & = 1000000\\ t^2&=\dfrac{1000000}{500}\\ t^2 & = 2000\\ t & = \pm \sqrt{2000}\\ t & = \pm 44.72135955...\end{aligned}[/tex]

As time in positive, t = 44.72135955 only.

This tells us that the number of daily hits reaches 1,000,000 during the 44th day.

Answer:

The answer is 2^4=16

Step-by-step explanation:

The measure of the angle BAC is 72degrees

We have given that the

angle B=108 degrees and angle C=60 degrees.

We have to determine angle A

In parallelogram

The sum of the two angles is 180 degrees.

Therefore we get,

angle A+ angle B=180 degrees

angle B=108 degrees

angle A +108=180

angleA=180-108

angleA=72 degrees.

Therefore the measure of the angle A is 72degrees
