Pauline’s Pie’s baked 150 pies before they opened the store on Sunday. Once the store opened, they sold 30% of the pies before noon. How many pies were sold before noon?
Answer:
105
Step-by-step explanation:
First, in problems like these, you have to find 30% of 150. 30% of 150 is 45. Now, since you want to see how many pies have been sold, you do 150-45, which will give you 105.

. Given the number n, write an expression for:
(a) Twice the sum of n and 5
(b) The sum of twice n and 5
© Give a numerical example that shows these are not the same expression.
Answer:
a) 2(n + 5)
b) 2n + 5
Step-by-step explanation:
Writing an algebraic expression:
a) Sum of n and 5 ⇒ n + 5
Twice sum of n and 5 ⇒ 2*(n +5) = 2*n + 2*5
= 2n + 10
b) Twice n ⇒ 2*n = n
Sum of twice n and 5 ⇒ 2n + 5

Find the surface area of the pyramid.
Answer:
319
Step-by-step explanation:
So, to find the surface area, first we find the base area, which is: 11 x 11 = 121
Then, we have to find the area of the other faces. Since each face is a triangle, we can use the formula A = 1/2 x b x h.
So,
b = 11
h = 9
1/2 x 11 x 9 = 49.5
The, we multiply by 4, the number of sides: 49.5 x 4 = 198
Then, we add the 2, values: 121 + 198,
Which gives us: 319.
Hope this helped!

WXYZ is a parallelogram. What is the angle DZW?
The correct angle measurement DZW = 55°
How to find the angle DZW?Note the following parameters
, m∠W = 125° and m∠Z = 55°
The measure of angle <DYZ is given as:
<DYZ = 125 ⁰
The opposite angles of a parallelogram are equal.
This means that, angles W and Y have equal measures
This implies that
<ZWZ = <DYZ
<XWZ=125
The adjacent angle of a parallelogram add up to 180 degrees.
This is to say that
<DXW = 180 - <DYZ
<DXW= 180-125
<DXW= 25
Angles X and Z are equal because they are opposite angles.
This is to say that
<Z = 55
Hence, the measure of angle DZW is 55⁰

The graph relates the temperature change y (in degrees Fahrenheit) to the altitude change x (in thousands of feet). Altitude Change
Based on the relationship between the temperature and altitude change, the slope is -3.6 and the y-intercept is 59. The equation of the line is y = - 3.6x + 59.
What is the equation for this line on altitude change v. temperature change?First find the slope. This can be found by the formula:
= (Y₂ - Y₁) / (x₂ - x₁)
Two points on line:
(0, 59) and (7, 33.8)
Slope is:
= (33.8 - 59) / (7 - 0)
= -3.6
The y intercept is the point the line crosses the y axis which is 59.
The formula is:
y = mx + c
Where;
m = slope
c = y intercept
So the equation is:
y = -3.6x + 59

In a random sample of 74 homeowners in a city, 22 homeowners said they would
support a ban on nonnatural lawn fertilizers to protect fish in the local waterways. the sampling
method had a margin of error of +3.1%.
a) find the point estimate.
b) find the lower and upper limits and state the interval.
The point estimate is 29.73% and the lower and upper limits are 26.63% and 32.83% respectively.
What is the margin of error(MOE)?It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
[tex]\rm MOE = Z\times \dfrac{s}{\sqrt{n}}[/tex]
Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
Point estimate = 22/74 = 0.2973 = 29.73%
Lower limit = point estimate - MOE = 29.73 - 3.1 = 26.63%
Upper limit = point estimate + MOE = 29.73 + 3.1 = 32.83%
Thus, the point estimate is 29.73% and the lower and upper limits are 26.63% and 32.83% respectively.

tan2x=___
A. tan x/1+tan^2 x
B. tan x/1-tan^2 x
C. 2tan x/1-tan^2 x
D. 2tan x/1+tan^2 x
Step-by-step explanation:
tan2x = sin2x/cos2x
we know that ,
sin2x = 2sinxcosx sin2x = 2sinxcosx cos2x = cos²x - sin²xSince, tan2x = 2sinx*cosx/cos²x- sin²x
Dividing by cos²x in numerator and denominator.
We get ,
tan2x = 2sinx/cosx / 1- sin²x/cos²x Since, we get tan2x= 2tanx/1-tan²x Option (c) is correct option. Hope it will be helpfulPlsss help meee. Worth 15 points<3
