Answer:
the sum of A, B, C and E = 23Explanation:
single cone = $3
double cone = $5
total single = A = 3s
total double = B = 5d
As + Bd = 57
Cs + Ed = 15
A = 3 , B = 5
3s + 5d = 57
s + d = 15 (we don't know C and E yet)
multiply the second equation by 3 and substract it from the first equation
3s + 5d - 3s - 3d = 57 - 45
2d = 12
d = 6
Ed = 6
Cs = 15 - 6 = 9
A = 3 ($3)
B = 5 ($5)
C = 9 (single cones)
E = 6 (double cones)
Check:
(9 single cones × $3) + (6 double cones × $5) = 27 + 30 = 57
9 single cones + 6 double cones = 15
the sum of A, B, C and E:
A+B+C+E = 3+5+9+6 = 23

Answer:
30
Step-by-step explanation:
Solve for the hypotenuse for the bottom triangle (a^2+ b^2=c^2). You should get 40. After solving that you should be able to solve for c in the top triangle which should get you 30.
Priya is simplifying the expression $$ Her work is shown to the left. Priya's work is incorrect. Explain the error she made
Step-by-step explanation:
P.S - The exact question is -
Given - Priya is simplifying the expression -2(4 - 2x) - 3 - 2x Her work is shown to the left.
To find - Priya's work is incorrect. Explain the error she made.
Proof -
Priya simplified the problem as follows :
-2( 4 - 2x ) - 3 - 2x
-8 - 2x - 3 - 2x
-11 - 4x
But the simplification has to be like
-2( 4 - 2x ) - 3 - 2x
⇒-2(4) - 2(-2x) - 3 - 2x
⇒-8 + 4x - 3 - 2x
⇒-8 - 3 + 4x - 2x
⇒-11 + 2x
So, Priya made an error in the second line.
In the second line it has to be -8 + 4x - 3 - 2x but Priya has written -8 - 2x - 3 - 2x.

I need help with this! Which one is it?
Answer:
82 degrees
let the point where the lines cross be E
ABD angle is 108 / 2 = 54 degrees
CAB angle is 56 / 2 = 28 degrees
the missing angle in ABE triangle is 180-54-28=98 degrees. angle x is 180 - 98 = 82

Which equation represents a proportional relationship where the constant of proportionality is 2? * y=2+k k=2y y=2+x y=2x
Answer:
y = 2x
Step-by-step explanation:
here in this case, x = independent variable whereas y is the dependent variable.
Now, Equation that represents a proportional relationship with a constant or proportionality of 2 is y =2x.
as y= 2x
⇒ y/x = 2
Find the value of x.
Answer:
x = 45
Step-by-step explanation:
All triangles add up to 180°
x + 75 + 60 = 180
x + 135 = 180
x = 180 - 135
x = 45
What is an equation of the line that passes through the points (7, 4) and ( -5, 4)?
Answer:
y = 4
Step-by-step explanation:
To find the slope, you plug the coordinates into the slope formula.
y2 - y1/ x2 - x1
= 4 - 4/ -5 - 7
= 0
The slope is 0.
To find the y-intercept, y = 0x + b
4 = 0(7) + b
4 = 0 + b
4 = b
The equation is y = 4

< PREVIOUS
Answer:
600,000 km²
Step-by-step explanation:
Using the exponential regression calculator : the regression fit obtained for the data is :
36510 * (1.08^x)
After 40 years ;
x = 40
Hence,
y = 36510 * 1.08^40
y = 36510 * 21.72452
y = 793,162.27 km
Hence, y is closest to 800,000 km
Triangle Ratios (Sides)
Find the value of c. Round to the nearest tenth!
Answer:
x =30.7
Step-by-step explanation:
Here, we want to find the value of x
To get this, we use the appropriate trigonometric ratio
From what we have, we have the side facing an angle which is the opposite and the side not facing an angle or the right angle; this is the adjacent
The trigonometric identity that links the opposite and the adjacent is called the tan
It is the ratio of the opposite to the adjacent
Thus, we have;
tan 61 = x/17
x = 17 * tan 61
x = 30.7

Answer:
Step-by-step explanation:
so a rhombus is two triangles put together, the area of a triangle is 1/2 b*h and since we've got two it's 2 ( 1/2 b * h ) so then it' just b * h
will be the area of the rhombus.
the base is WY = 24 the height is 1/2 XZ = 30 so 15
