Answer:
Total cost= $31
Step-by-step explanation:
Giving the following information:
The rental fee for a mo-ped was $10 plus $7 for each hour he used the bike.
First, we need to structure the total cost formula:
Total cost= 10 + 7h
h= number of hours
Now, for 3 hours:
Total cost= 10 + 7*3
Total cost= $31

Kate stands 2 meters from a lamppost. She is 2.1 meters tall and casts a shadow 3 meters long in the light from the lamp. How tall is the lamppost? See diagram below.
Answer:
3.5 meters.
Step-by-step explanation:
Please refer to the attachment.
Since the two triangles share two congruent angles, by AA Similarity, the two triangles are similar.
Therefore, we can write the following proportion:
[tex]\frac{3}{5}=\frac{2.1}{x}[/tex]
To find the height of the lamppost x, we will simply have to solve for x.
So, let’s cross-multiply:
[tex]10.5=3x[/tex]
Divide both sides by 3:
[tex]x=10.5/3=3.5[/tex]
Hence, the height of the lamppost is 3.5 meters.

We have,
The high temperature on Monday was -14 degrees.
On Tuesday the high temperature was 24 degrees.
The temperature difference between Monday and Tuesday.
= Temperature on Tuesday - Temperature on Monday
= 24 - (-14)
= 24 + 14
= 38

a fruit Shop sells dried fruit by the pound the cost for X pounds of raisins is represented by the equation y= 3.5x, where y is the total cost for X pounds. the cost for 4 pounds of dried cranberries is $18 Graph both proportional relationship on the grid to the right which fruit has the lower unit price? Explain.
y=4.5x the equation for cranberries
Step-by-step explanation:
So the easiest way to solve this would be take the $18 and divide it by the 4 pounds you then get the unit price per pound which is $4.5 a pound
A number is called flippy if its digits alternate between two distinct digits. For example, 2020 and 37373 are flippy, but 3883 and 123123 are not. How many five-digit flippy numbers are divisible by 15?
A 3
B 4
C 5
D 6
E 8
Answer:
A
Step-by-step explanation:
The number of five-digit flippy numbers are divisible by 15 is;
Option B; 4 Numbers
We want 5 digit flippy numbers that are divisible by 15.For a number to be divisible 15, it has to be divisible by 3 and 5.
Also, for a number to be divisible by 5, it's last digit has to be 0 or 5.
Since it is a flippy digit and 0 cannot start it as it is a five digit number, then the first and last digits must be 5. Also, the center digit must be 0 or 5 to fulfill both conditions.Thus, the format of the number should be;5N5N5
For it to be divisible by 3, since 5 + 5 + 5 = 15 is divisible by 3, the N + N can be equal to 0, 6, 12, or 18 since N is identical.
Thus, possible numbers are; 50505, 53535, 56565, 59595.Read more at; https://brainly.com/question/19238760

Answer:
11 7/16
Step-by-step explanation:
The integration resolves into finding the area of two triangles. The left has a height of (-3/8(-2/3)+2) = 2 1/4, and a width of (16/3-(-2/3)) = 6. Then its area is ...
A = (1/2)bh = (1/2)(6)(2 1/4) = 6 3/4
__
The right triangle has a height of |(-3/8)(31/3) +2| = |-31/8+16/8| = 15/8. Its width is (31/3) -(16/3) = 5, so its area is ...
A = (1/2)(5)(15/8) = 75/16 = 4 11/16
Then the total area, the value of the integral, is ...
6 3/4 +4 11/16 = 10 23/16 = 11 7/16 . . . the value of the integral

'Solve 4x- c= k for x.
Answer:The answer would be x=c+k/4
Step-by-step explanation:
The required solution for the equation ax -c = k for x is x = (k + c)/4.
Given that,
To determine the solution of the equation 4x- c= k for x.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
4x - c = k
Now, simplifying the above equation for x,
4x - c = k
4x = c + k
x = (c + k) / 4

Answer:
angles (W, X, Y) = (77°, 62°, 41°)
Step-by-step explanation:
Given:
ΔWZY
∠W = 2(∠Y) -5°
∠X = ∠Y +21°
Find:
∠X, ∠Y, ∠W
Solution:
Using angle measures in degrees, we have ...
∠X + ∠Y + ∠Z = 180
(∠Y +21) +∠Y + (2(∠Y) -5) = 180
4(∠Y) +16 = 180 . . . . . simplify
∠Y +4 = 45 . . . . . . . . . divide by 4
∠Y = 41 . . . . . . . . . . . . subtract 4
∠W = 2(41) -5 = 77
∠X = 41 +21 = 62
The angle measures of angles (W, X, Y) are (77°, 62°, 41°), respectively.
Find the 87th term of the arithmetic sequence 12, 0, -12,
Answer:
- 1020
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = a₂ - a₁ = 0 - 12 = - 12 , thus
a₈₇ = 12 + (86 × - 12) = 12 - 1032 = - 1020
Answer:
-1008
Step-by-step explanation:
A florist delivers flowers to anywhere in town. D is the distance from the delivery address to the florist shop in miles. The cost to deliver flowers, based on the distance d, is given by C(d) = 0.04d^3 - 0.65d^2 + 3.5d + 9. Evaluate C(d) for d = 6 and d = 11, and describe what the values of the function represent
A. C (6) = 15.24; C 11 = 22.09.
C (6) represents the cost, $15.24, of delivering flowers to a destination that is 6 miles
from the shop.
C (11) represents the cost, $22.09, of delivering flowers to a destination that is 11 miles
from the shop.
b.
Answer:
The distance between the library and the florist’s shop is the length of CD . The endpoints of this line segment are C(3, 4) and D(3, -3). Because the x-coordinates of both points are the same (3), the length of CD can be found by subtracting the smaller y-coordinate from the greater y-coordinate: CD = 4 – (-3) = 4 + 3 = 7 units. The distance between the library and the florist’s shop is 7 blocks.

If z is a positive integer, does 4+3(2z-5) represent a number that is greater than, less than, or equal to 2(3z-4)?
Answer:
Step-by-step explanation:
4 + 6z - 15 = 6z - 11
2(3z -4) = 6z - 8
Here's the tricky part. You are only taking 8 away from 6z
The result is going to be larger than when you take away 11 from 6x
Try it
suppose z = 7
6*7 - 8 = 42 - 8 = 34
6*7 - 11 = 42 - 11 = 31

The ratio of fiction to non-fiction books at school library is 3 to 5. If there are 240 books in the library how many non-fiction books are in the library?
Answer:
150
Step-by-step explanation:
The ratio is 3:5, so you can make this equation:
[tex]3x+5x=240[/tex], because for any integer x, the ratio will stay the same.
solve that:
[tex]3x+5x=240\\8x=240\\x=30[/tex]
We're not down yet!
we need to find 5x, not x.
[tex]5*30=150[/tex]
There are 150 non-fiction books in the library.
check!
150+90=240
The are 150 non-fiction books are in the library.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
The ratio of fiction to non-fiction books at school library is 3 to 5.
Total books = 240
So, the number of non fiction books
= 240 x 5/8
= 30 x5
= 150
Hence, there are 150 non fiction book.
