5(y+2)= -3
Help please TvT
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 ✔️

Find the area of the following
trapezoid:
12 cm
/ 0.00
8 cm
Enter
10 cm
22 cm
A = [?] cm²
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

Find the area of the shape.
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.

FIND THE VALUE OF X
123°
Step-by-step explanation: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.
[tex]180=55+68+y[/tex]Then, solve for y by subtracting 55 and 68 from both sides.
[tex]57=y[/tex]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.
[tex]180=57+x[/tex]Next, solve the formula by subtracting 57 from both sides.
[tex]123=x[/tex]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:
f = number of daily hitst = times (in days)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.

Given that /ABC = 108° and /BCD = 60°, calculate /BAC (Parallelogram)
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
What is the sum of the two angles?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

A cube of side 14 cm is surmounted by a hemisphere. What is the greatest diameter the hemisphere can have? Find the surface area of the solid?
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

A biologist is studying the weights of female polar bears in the Arctic and finds that the mean weight is 179 kg with a standard deviation of 63 kg. Assume weights are normally distributed. What is the weight of a polar bear at the 30th percentile?
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
