Mary, Hans, and Alan have a total of $54 in their wallets. Mary has $10 more than Hans. Alan has 2 times what Mary has. How much do they have in their
wallets
Answers
Answer: $95
Step-by-step explanation:
Let's say Maria is M, Hans is H and Alan is A. Maria has M amount of money. If Hans has 10 more than Maria, he has M+10. If Alan has 3 times what Hans has and Hans has (M+10), then Alan has 3(M+10) which is 3M+30. Altogether they have 95 dollars. So we will add up what they have and set it equal to 95. M+10+M+30+3M=95. That simplifies to 5M+40=95 and 5M=55. Therefore, Maria has 11 dollars. Hans has 10+11=21, and Alan has 3(21)=63. 11+21+63=95

T=2rh + 2r^2 ; for h
Answers
so we need to isolate the part that has h
so we would subtract 2r^2
T - 2r^2 = 2rh
the we would need to divide by 2r
(T - 2r^2)/2r = h
but we can simplify the left side
T/2r - 2r = h

Answer:
k = 4.5
y = 4.5x . . . y bracelets in x hours
Step-by-step explanation:
The constant of proportionality is the "unit rate", the number of bracelets per hour.
k = bracelets/hours = 36/8 = 4.5
The constant of proportionality is 4.5 (bracelets per hour).

All 3 sides of the triangle are the same, which means all 3 inside angles are the same. Each inside angle is 60 degrees.
We now have 3x = 60
Divide both sides by 3:
x = 60/3
x = 20
Answer:
As in the given figure, all the sides are equal i.e., 5 units
It is a equilateral triangle.
In equilateral triangle all the angles are 60°.
[tex]3x = 60 \\ x = \frac{60}{3} \\ \boxed{x = 20}[/tex]

Step-by-step explanation:
Similar Triangles
If two triangles are similar, then:
* All the corresponding side lengths are proportional by the same scale factor
* All the internal angles are congruent.
The image provided in the question has two similar triangles TYZ and TWX. We have completed the shape with a variable p =TZ, whose value will be determined by applying the first similarity condition above.
The ratio between the heights is 20:16, and the proportion between the bases is (6+p):p, thus:
[tex]\displaystyle \frac{6+p}{p}=\frac{20}{16}=\frac{5}{4}[/tex]
Cross-multiplying denominators:
4(6 + p) = 5p
24 + 4p = 5p
Solving for p:
p = 24
Then, TZ = 24

Find the measure of angle B
(9x+2) (5x-4)
Answers
Answer:
119
Step-by-step explanation:
[tex]due \: to \: Corresponding \: angles \\ (5x - 4) + (9x + 2) = 180 \\ 14x = 182 \\ x = 13 \\ \\ 9.13 + 2 = b \\ b = 119[/tex]
Answer:
In the given figure, we know that (angle B+angle C)=180°.
[tex](9x + 2) + (5x - 4) = 180 \\ 14x - 2 = 180 \\ 14x = 182 \\ \boxed{x = 13}[/tex]
Angle B = (9x+2) = (9×13+2) = (117+2) = 119°.
Which expression is equivalent to 20+64
a.4+(16+60)
b.4+(5+16)
c.4+(16+60)
d.4(5+16)
Answers
Answer:
D. 4 (5 + 16)
Step-by-step explanation:
20 + 64 = 84
To solve this problem we have to simplify each of the expressions in the answer column:
A. = 80
(16 + 60 = 76) giving us
4 + 76 = 80
B. = 25
(5 + 16 = 21)
4 + 21 = 25
C. = 80
(16 + 60 = 76)
4 + 76 = 80
D. = 84
(5 + 16 = 21)
4 x 21 = 84
So The correct option is D. 4 (5 + 16)
