Find the surface area of the pyramid. The side lengths of the base are equal.
__________
If you cant see the numbers
* Bottom number is 13m and the one with an arrow is 18 m
Again sorry if you cant see it
Answers
Answer: 637 m²
Step-by-step explanation:
We need to find the area of four triangles and one square.
The square: 169 m²
A = L²
A = (13 m)²
A = 169 m²
The triangles: 468 m²
-> We have four congruent triangles. I will find the area of two (skipping the "divide by two" part of the formula) and multiply by two to find all four at once.
A = B * H
A = (13 m) * (18 m)
A = 234 m²
-
234 m² * 2 = 468 m²
Total surface area:
169 m² + 468 m² = 637 m²

Answer:
Scale factor of 1/2.
Step-by-step explanation:
Note that the comparison is figure A to figure B'.
The original measurements that are given are the side measurements of 16 & 6. In comparison to the corresponding parts for the other figure, it would be 8 & 3 respectfully.
Find the factor in which they change by multiplying.
16x = 8
6x = 3
Isolate the variable by dividing:
(16x)/16 = (8)/16
x = 8/16 = 1/2
(6x)/6 = (3)/6
x = 3/6 = 1/2
The scale factor is 1/2.

A=31.64 B= 18.34 C= 130.20
Step-by-step explanation:
calculating for A using cosine rule
50^2= 30^2+73^2-2×30×73CosA
2500= 900+5329-4380COSA
2500= 6329-4380COSA
2500-6329= -4380COSA
-3729= -4380COSA
COA= -3729/-4380
COSA= 0.8514
A=COS^-1(0.8514)
A= 31.64
calculating B using sinerule
sin 31.64/50= sinB/30
sinB = sin31.64×30/50
sinB = 0.3147

Answer:
D. 36.75-3x
Step-by-step explanation:
You have a total amount of 36.75.
Since you are spending money you need to subtract.
We know that Marshall buys 3 tickets.
We also know that 'x represents the amount of a single ticket.
Remember that they are asking you for an algebraic expression and not an equation.
So you need to take away from your total, 36.75. And since you plan on buying three tickets and aren't given the amount x it leaves you with taking 3x from your total 36.75 or an other words
D. 36.75 - 3x

when a line is perpendicular the line is negative and reciprocal.y
y=2x+6
now we substitute.
-4=2(5)+b
-4=10+b
-14=b is your answer
Step-by-step explanation:
Hlew frnd!
To find the slope of the perpendicular line we just take the reciprocal and therefore change the sign of slope,
Perpendicular to y = -½x + 6
Hence, the slope will be = -½ = 2
Now we have to find the slope-intercept form, So
here y intercept is given and the point will be (0,b) then eqs. of line,
=> y = mx + b [slope-intercept form]
=> -4 = 2*5 + b
=> -4 = 10 + b
=> b = -14

Tax revenue = $3000
Government transfer payments = $1000
Government spending = $3000

b) What is the current budget balance in Rayton? Show your work.
c) Senator Fullington, an influential politician in Rayton, has argued that the budget must be
balanced. How could this be accomplished? How would balancing the budget affect real GDP in
Rayton?
Answers
Based on the current real and the full employment real GDP, Rayton's economy is at a Recession stage.
The current budget balance in Rayton is -$1,000. The budget can be balanced by reducing government spending or increasing taxes. Both of these would decrease real GDP.
What does the economic data on GDP show?The fact that the current real GDP is less than the full employment GDP shows that the nation is at a recession stage where it is underperforming.
What is the current budget balance?This can be found as:
= Government revenue(taxes) - government spending
= 3,000 - 1,000 - 3,000
= -$4,000
In order to make a balanced budget where government revenue will equal government spending, the government either needs to reduce spending or increase revenue ( taxes ).
Increasing taxes or reducing spending, will lead to less money available for spending in the economy which will lead to a decrease in real GDP.
