Answer:
[tex]43.7[/tex]
Step-by-step explanation:
Since the triangles are similar, the ratio of their corresponding sides is maintained. Therefore, we can up the following proportion to solve for [tex]OP[/tex]:
[tex]\frac{9}{7}=\frac{OP}{34},\\OP=\frac{34\cdot 9}{7}=43.7142857143\approx \boxed{43.7}[/tex]
43.7
Step-by-step explanation:
Since the two are similar triangles, the ratio of the legs of one triangle is equal to the ratio of the legs of the other triangle.
OP/ON = LM/LK
OP/34 = 9/7
Solving for OP,
OP = 34(9/7)
= 43.7
Which exponential equation is equivalent to this logarithmic equation?
log5 x - log5 25 = 7
A. 7^9=x
B. 5^9=x
C. 7^5=x
D. 5^5=x
Answer:
[tex] \displaystyle B)x = {5}^{9} [/tex]
Step-by-step explanation:
we are given a logarithmic equation
[tex] \displaystyle \log_{5}(x) - \log_{5}(25) = 7[/tex]
simplify the log:
[tex] \displaystyle \log_{5}(x) -2 = 7[/tex]
add 2 to both sides:
[tex] \displaystyle \log_{5}(x) = 9[/tex]
remember that,
[tex] \displaystyle \log_{a}(b) = c \iff {a}^{c} = b[/tex]
so we obtain:
[tex] \displaystyle x = {5}^{9} [/tex]
hence,
our answer is B)
A boat is travelling from point c toward point d which is on the shoreline the shoreline is represented by the line through point a and point b
Answer:
The answer is "lines CD & AB are perpendicular ".
Step-by-step explanation:
Given points:
[tex]A=(0,7)\\\\B=(8,-5)\\\\C=(-3,-8)\\\\D=(6,-2)[/tex]
Calculating the slope of AB: [tex]y = -\frac{12}{8}x + 7[/tex]
Calculating the slope of CD: [tex]y = \frac{6}{9}x - 6[/tex]
simplify the slop:
[tex]AB= -\frac{3}{2}\\\\CD=\frac{2}{3}\\\\[/tex]
Recall what you know about similarity. If circle B is similar to circle A, what must exist?
The similarities of two circles is dependent on the radius of circle A and circle B. So the radius of both circles must exist for the circles to be similar.
Given that:
Circles A and B
To prove the similarities of the two circles, the radius of both circles must be known.
Assume the radius of circle A is [tex]r_A[/tex] and the radius of circle B is [tex]r_B[/tex].
The similarity of both circles is proved using:
[tex]r_A = k * r_B[/tex]
or
[tex]r_B = k * r_A[/tex]
where k represents the scale of dilation
Hence, the radius of both circles must exist for the circles to be similar.

x+y=80
5x+8y=535
what is x and what is y
Answer:
x+y=80 i.e. 5x+5y=400 multiplying both sides by 5
now 5x+8y=535
therefore 3y=535-400=135
therefore y=135/3=45
now x=80-y=80-45=35
therefore final answer x is 35 y is 45
Answer:
x=35, y=45
Step-by-step explanation:
x+y=80=>5x+5y=400 so (5x+8y)-(5x+5y)=535-400
<=>3y=135<=>y=45=>x=80-y=80-45=35

Answer:
x/7 - 2 = y
Step-by-step explanation:
To find the inverse of a function, we switch f(x) and x and then solve for f(x). We thus have
x = 7f(x) + 14
subtract 14 from both sides to isolate the f(x) and its coefficient
x - 14 = 7 f(x)
divide both sides by 7 to isolate the f(x)
(x-14)/7 = f(x)
f(x) is synonymous with y here. so we havt
(x-14)/7 = y
This can also be written as
x/7 - 14/7 = y
x/7 - 2 = y

Answer:
y= -3x+5
Step-by-step explanation:
It's kind of hard to see but I'm going to assume it looks like
y-2=(1/3)(x-1)
Let's start by converting this into slope-intercept form
y-2=x/3-1/3
y=x/3+2/3
One line is perpendicular to another line if their slopes are negative reciprocals of each other
our slope now is 1/3 which means its negative reciprocal is -3
so we have
y= -3x+b
Plug in the required coordiante to solve for b
2= -3(1)+b
2= -3+b
b= 5
put it together to get
-3x+5

John got $30 for weeding the garden. He used money to buy a $15.25 video game and three snacks that cost $1.25 each. He bought his friend a snack too. If he went home with 1/6 of the money he started with, how much did his friends snack cost? A $5.00 B $6.00 C $8.50 D $11.00 E $13.50 F $14.75
Answer:
B
Step-by-step explanation:
His friends snack was 6 dollars.
15.25+1.25= 16
16+1.25= 17.25
17.25+1.25= 19
1/6 of 30 is 5 because 5x6=30.
30-19=11
He has to have 5 left over so the snack was 6 dollars.

I need help I put 30 points for whoever helps me
Answer:
[tex]y=-x+1[/tex]
Step-by-step explanation:
Slope can be represented as rise over run (change y-values over change in x-values). Since the y-value is changing by -2 every time the x-value is changing by 2, the slope of the line must be [tex]\frac{-2}{2}=-1[/tex].
In slope-intercept form [tex]y=mx+b[/tex], [tex]m[/tex] represents the slope of the line, [tex]b[/tex] represents the y-intercept, and [tex](x, y)[/tex] represent the coordinates of any point the line passes through.
To find [tex]b[/tex], substitute [tex]m=-1[/tex] and any point the line passes through.
Using (1, 0) from the table:
[tex]0=-1(1)+b,\\0=-1+b,\\b=1[/tex]
Thus, the equation of this line is [tex]\boxed{y=-x+1}[/tex]

Polygon DRMF is congruent to SLTO. Name two sets of congruent angles and two sets of congruent sides.
Answer:
✔️2 sets of corresponding angles
<D and <S
<R and <L
✔️2 sets of corresponding sides
DR and SL
RM and LT
Step-by-step explanation:
When two polygons are congruent, it implies that they have the same shape and size. Therefore, their corresponding angles and sides are congruent to each other.
When naming congruent polygons, the arrangement of the vertices are kept in a definite order of arrangement.
Therefore, Given that polygon DRMF is congruent to SLTO, the following angles and sides correspond to each other:
<D corresponds to <S
<R corresponds to <L
<M corresponds to <T
<F corresponds to <O
For the sides, we have:
DR corresponds to SL
RM corresponds to LT
MF corresponds to TO
FD corresponds to OS.
We can select any two out of these sets of corresponding angles and sides as our answer. Thus:
✔️2 sets of corresponding angles
<D and <S
<R and <L
✔️2 sets of corresponding sides
DR and SL
RM and LT

Luis put out 6 different pies at a picnic at the end of the picnic, he noticed this about the pies: one whole apple pie was eaten, and 3/4 of another apple pie was eaten 1/2 of the blackberry pie was eaten 1/8 of the blueberry pie was eaten 5/8 of the cherry pie was eaten 3/4 of the peach pie was eaten. What is the total amount of pies that where left over
amount left of apple pie = 1 - 3/4 = 1/4
amount left of blackberry pie = 1 - 1/2 = 1/2
amount left of blueberry pie = 1 - 1/8 = 7/8
amount left of cherry pie = 1 - 5/8 = 3/8
amount left of peach pie = 1 - 3/4 = 1/4
add this figures together
[tex]\frac{2 + 4 + 7 + 3 + 2 }{8}[/tex] = [tex]\frac{18}{8}[/tex] = [tex]2\frac{2}{8}[/tex] = 2[tex]\frac{1}{4}[/tex]

1. Volume of a pyramid: 192 ftº: Volume of a rectangular prism:
2. Volume of a pyramid:
Volume of a rectangular prism: 729m
3. Volume of a cylinder: 285 cm: Volume of a cone:
4. Volume of a sphere:
Volume of a cylinder: 600cm
5. Volume of a cone: 50 m: Volume of a cylinder:
Answer:
576 FT^3
243 m^3
95 cm^3
400 cm^3
150 m^3
Step-by-step explanation:
Volume of a pyramid = 1/3 x ( length base x height)
Volume of a prism= ( length base x height)
1. prism = 192 x 3 = 576 FT^3
2. prism = 729 / 3 = 243 ft^3
volume of a cylinder = nr^2h
Volume of a cone = 1/3(nr^2h)
3. cone = 285/3 = 95
5. cylinder = 50 x 3 = 150
4. sphere = 600 / 1.5 = 400
