I NEED HELPP Solve for PMR please
The angle PMR in the quadrilateral is 32 degrees.
How to find the angle PMR?The angle PMR can be found as follows;
The line AP is an angle bisector of angle RPM. Therefore, the following relationships are formed.
∠RPM ≅ ∠WPM
Hence,
∠RPM ≅ ∠WPM = 58 degrees
Therefore,
∠WPM = 58 degrees
∠PWM = 90 degrees
Let's find ∠PMR as follows
∠PMR = 180 - 90 - 58
∠PMR = 90 - 58
∠PMR = 32 degrees

Find the Surface Area of the square Pyramid.
Answer:
867 cm^2
Step-by-step explanation:
Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region. 2y=3√x,y=3, and 2y+1x=4
The area of the region is approximately 0.81.We can start by plotting the curves to get a sense of the region we need to integrate over:
2y = 3√x => y = (3/2)√x
y = 3
2y + x = 4 => y = (4-x)/2
The region is enclosed by the curves y = (3/2)√x, y = 3, and y = (4-x)/2, as shown below:
| /\
3 | / \
| / \
| / \
| / \
| /__________\
| 0 2 4 x
---|--------------------------
| y = 3
To find the area of this region, we can integrate with respect to x or y. Looking at the curves, it seems more natural to integrate with respect to x, so we will do that.
We can see that the curves intersect at (4,0) and (16/9,2). Therefore, we need to integrate over the interval [0, 16/9]:
Area = ∫[0, 16/9] [(4-x)/2 - (3/2)√x] dx
Expanding the integral and simplifying:
Area = ∫[0, 16/9] (2-x/2 - (3/2)√x) dx
= [2x - (x^2/4) - (4/5)x^(5/2)/3] |[0, 16/9]
≈ 0.81
Therefore, the area of the region is approximately 0.81.

Referring to the figure, the two rectangles shown have
equal areas. Find the value of x.
Answer:
x = 2
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × breadth
given the rectangles have equal areas then equating the two areas gives
4x × 9 = 4(6x + 6) , that is
36x = 24x + 24 ( subtract 24x from both sides )
12x = 24 ( divide both sides by 12 )
x = 2
Martin harvested 60 kilograms of mangoes last February, twice as much in March, and 20 kilograms more in April than the combined harvest in February and March. How many kilograms of mangoes did he harvest in all? (A little side story: My sibling needs help on this and I'm not really confident in word problems. This has been my weakness since I was very young but now I can manage haha btw thanks for the help)
Answer:
Lets express this as equations to get a better idea of this situation.
let f represent February, m represent march and so on
60 mangoes in feburary
(60)2=m
m=120
120 mangoes in march
A=120+60+20
a=200
m+f+a=total amount of mangoes
60+120+200=t
380=total
Step-by-step explanation:
The total mangoes harvested by Martin is 380 kilograms.
What are word problems?A word problem in math is a math question written as one sentence or more that requires children to apply their math knowledge to a 'real-life' scenario.
Given that, Martin harvested 60 kilograms of mangoes last February, twice as much in March, and 20 kilograms more in April than the combined harvest in February and March.
We need to find the total harvested mangoes,
Let f represent February, m represent march and April be a
February = 60 mangoes
So, in March,
(60) 2 = m
m = 120
Therefore, 120 mangoes in March
A = 120+60+20
a = 200
Now, the total mangoes = 60+120+200 = 380
Hence the total mangoes harvested by Martin is 380 kilograms.

How does (x^3)^3 = x^6 ?
Answer:
It does not, unless \(x=0\) or \(x=1\)
If you remember how to raise a power to a given power you remember to multiply the exponents (or, if you don't, apply the definition of \((x^3)^3=(x^3)(x^3)(x^3)=x^9\)
At this point you're being asked if \(x^9=x^6\) and the only two numbers for which this is true are 0 and 1 (side note: if the left hand side was an even function also \(-1\) was a possible candidate, but alas 9 is odd).
Find the length of AB.
The measure of the length of segment AB in the triangle is 20 units.
What is the measure of length AB?The figure in the image is of two similar triangles:
From the image,
For the smaller triangle:
Leg 1 AP = 12
Leg 2 AQ = 8
For the larger triangle:
Leg 1 AC = 12 + 18 = 30
Leg 2 AB = 8 + QB
First, we determine length QB, we take the ratio of the sides of the two triangle since they similar:
Hence:
Leg 1 AP : Leg 2 AQ = Leg 1 AC : Leg 2 AB
12 : 8 = 30 : ( 8 + QB )
12/8 = 30/( 8 + QB )
Solve for QB:
12( 8 + QB ) = 8 × 30
96 + 12QB = 240
12QB = 240 - 96
12QB = 144
QB = 144/12
QB = 12
Now,
Leg 2 AB = 8 + QB
Plug in QB = 12:
Leg 2 AB = 8 + 12
Leg 2 AB = 20
Therefore, AB measure 20 units.

Manuel ordered pizza for a party. A vegetable pizza has 6 slices per pie. A cheese pizza has 8 slices per pie. Manuel ordered four times as many cheese pizzas as vegetable pizzas, for a total of 152 slices. How many pizzas did Manuel order? 15 20 30 40
Answer:
20 Pizza
Step-by-step explanation:
Let the number of vegetable pizza be x
Given that
Manuel ordered four times as many cheese pizzas as vegetable pizzas
the number of cheese pizza = 4x
1. no of slice in 1 vegetable pizza pie = 6
no of slice in x vegetable pizza pie = 6x
2. no of slice in 1 cheese pizza pie = 8
no of slice in 4x cheese pizza pie = 8*4x = 32x
Total no of slice for x vegetable pizza and 4x cheese pizza = 6x+32x = 38x
Given that
total no. of 152 slices, therefore
38x = 152
=> x = 152/38 = 4
Thus, no. of vegetable pizza ordered = 4
no. of cheese pizza ordered = 4x = 4*$ = 16
Total no of pizza ordered = 16+4 = 20 (answer)

C Ask 10 people from each grade level at Allison's school how many games they have on their phones.
D Ask 5 teenagers from 20 different countries how many games they have on their phones.
The answer choice which gives the best-example of the "random-sample" is (c) Ask 10 people from each "grade-level" at Allison's school about how many games they have on their phones.
A "Random-Sample" is a subset of a larger population which is chosen in such a way that each member of the population has an equal chance of being selected.
The Option (c) : gives the best example of a random sample that Allison could use to help answer her question. By asking 10 people from each grade level at her school, Allison can obtain a sample that includes a variety of ages, genders, and backgrounds.
This can help to ensure that the sample is representative of the population she is interested in studying.
Option (a) : is not a random sample because it only includes teenagers who happen to be at the grocery store at the time Allison is conducting her survey. This may not represent entire population of teenagers at her school.
Option (b) : is not a random sample either because it only includes people who happen to be at the library on Saturday morning. This may not be representative of the entire population of teenagers at her school.
Option (d) : is not a random sample because it only includes teenagers from 20 different countries. This may not be representative of the population of teenagers at Allison's school or in her local area.

Solve for x, in terms of y: 23 x + 15 y = 2
MAKE BRAINLYST AND 100
To solve for x in terms of y in the equation 23x + 15y = 2, we can start by isolating the term with x on one side of the equation. We can do this by subtracting 15y from both sides of the equation to get 23x + 15y - 15y = 2 - 15y, which simplifies to 23x = 2 - 15y.
Next, we can solve for x by dividing both sides of the equation by 23 to get 23x/23 = (2 - 15y)/23, which simplifies to x = (2 - 15y)/23.
Therefore, the solution for x in terms of y is x = (2 - 15y)/23.

The scores on a standardized test are normally distributed with a mean of 80 and standard
deviation of 5. What test score is 0.9 standard deviations above the mean?
Answer:
84.5
Step-by-step explanation:
Given :
Mean μ = 80
Standard deviation, σ = 5
Z = number of standard deviations from the mean, Z = 0.9
Teat score, x
Using the Zscore formula :
Zscore = (x - μ) / σ
Plugging in our values :
0.9 = (x - 80) / 5
Cross multiply
0.9 * 5 = x - 80
4.5 = x - 80
4.5 + 80 = x
x = 84.5
