The exchange rate is $1 = 290 forints.
Calculate how many dollars Levante receives.
Someone helpppppp
The relation between the dollars and forints will be directly proportional. Then the number of dollars will be $ 85.
What are ratio and proportion?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
Levante changes 24 650 Hungarian forints to dollars.
Then the relation between the dollars and forints will be directly proportional. Then we have
Let x be the number of the dollars. Then we have
x / 1 = 24650 / 290
x = $ 85

Suppose a normal distribution has a mean of 62 and a standard deviation of
4. What is the probability that a data value is between 57 and 65? Round your
answer to the nearest tenth of a percent.
A.66.8%
B.67.8%
C.69.8%
D.68.8%
Answer:
0.66772
Step-by-step explanation:
Given that :
Mean (m) = 62
Standard deviation (s) = 4
probability that a data value is between 57 and 65
P(57 < x < 65)
Using the relation :
(x - m) / s
P(x < 57) :
(57 - 62) / 4 = - 1.25
P(Z < - 1.25) = 0.10565 ( Z probability calculator)
P(x < 65) :
(65 - 62) / 4 = 0.75
P(Z < 0.75) = 0.77337 (Z probability calculator)
P(Z < 0.75) - P(Z < - 1.25)
0.77337 - 0.10565 = 0.66772
Answer:
66.8%

Helppp pleaseee, abc= dce. If ac=5 and bc=7 cd=?
Answer:
CD = 5
Step-by-step explanation:
Given that ∆ACB is congruent to ∆DCE, it follows that their corresponding angles and corresponding side lengths are congruent to each other. Thus:
AC is congruent to CD,
BC is congruent to EC, and
AB is congruent to DE.
Since AC = 5, therefore CD = 5.

Which statements are true about the rectangle? Check
all that apply
The other sides of the rectangle measure 4 in. and
12 in
2 The perimeter, in cm, can be found using the
expression
(2 * 12) + (2 X 4).
The area can be found by multiplying 12 cm by 4
cm.
The volume can be found using the expression
12 cm x 4 cm x 4cm.
The rectangle has an area of 48 cm3
The true statements of the rectangle are as follows:
The other sides of the rectangle measures 4 inches and 12 inches. The perimeter in cm can be found using the expression (2×12)(2×4)The area can be found by multiplying 12 cm by 4 cm.The statements that are true in the option are highlighted with point listing.
The other sides of the rectangle measures 4 inches and 12 inches.Generally a rectangle has 2 opposite sides equal to each other.
The perimeter in cm can be found using the expression (2×12)(2×4)The perimeter of a rectangle can be express as follows:
perimeter = 2l +2w
where
w = width
l = length
The area can be found by multiplying 12 cm by 4 cm.The area of a rectangle can be express as follows
area = lw
The last 2 statement are not true statement because the volume of a rectangle cannot be found as it is a 2 dimensional figure and the units for area is squared but it was express in cm³(centimetre cube)

Line M contains points (4,3) and (1,2). Write a possible equation of line K that is
perpendicular to line M.
equation 1: 5x + 3y=8
equation 2: 4x + 7y= 34
9x-10y=42 true
Answer:
true
Step-by-step explanation:
5x + 4x = 9x
3y + 7y = 10y
8 + 34 = 42
Answer:
False
Step-by-step explanation:
5x+3y=8
4x+7y=34
Then:
5x+4x+3y+7y=9x+10y
9x+10y=43 not 9x-10y
Given the function h(t)=2f^2+9 evaluate h(5)

h(5) is equivalently h(t)Hence 2(5)^2+9So the answer is 59Answer:
h(5)=59
Step-by-step explanation:
The function h(t) should be h(t)=2t²+9 NOT 2f²+9
With that said,h(5)=2(5²)+9
