Answer: Total cost is $1.75
Explanation:
Since we have given that
Number of postcards bought by Doug's family= 7
Cost of each postcard including tax = $0.25
Total cost is given by
Now, we want to show this in number line :
On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.
Each step is of length 0.25 and there are 7 jumps to reach required answer.
So, after 7 jumps we reach at 1.75 which is the required answer.
Hence total cost is $1.75
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
For two lines to be perpendicular, the slope of one line is the negative reciprocal of the other line. The equation of the given line is
y = 2x - 2
Comparing with the slope intercept form,
Slope, m = 2
This means that the slope of the line that is perpendicular to it is -1/2
The given points are (-3, 5)
To determine c,
We will substitute m = -1/2, y = 5 and x = - 3 into the equation, y = mx + c
It becomes
5 = -1/2 × - 3 + c
5 = - 3/2 + c
c = 5 + 3/2
c = 13/2
The equation becomes
y = -x/2 + 13/2
Answer:
Step-by-step explanation:
An ellipse is the locus of a point such that its distances from two fixed points, called foci, have a sum that is equal to a positive constant.
The equation of an ellipse with a center at the origin and the x axis as the minor axis is given by:
Since the distance of the satellite from the surface of the moon varies from 357 km to 710 km, hence:
b = 357 km + 959 km = 1316 km
a = 710 km + 959 km = 1669 km
Therefore the equation of the ellipse is:
It would be a special purposes map :)
The number of blocks of clay needed by Hyla is 30 blocks
<h3>What is area?</h3>
Area is the region bounded by a plane shape.
To calculate the number of blocks of clay needed by Hyla, we find the area of the bottom of the box and divide it by the area of the block.
Formula:
- n = LWH/lwh............... Equation 1
Where:
- n = Number of blocks of clay needed by Hyla
- L = Length of the bottom of the box
- W = Width of the bottom of the box
- H = Height of the box
- l = Length of the bottom of the block
- w = Width of the block
- h = Height of the block.
From the question,
Given:
- L = 24 cm
- W = 20 cm
- H = 2 cm
- l = 4 cm
- w = 4 cm
- h = 2cm
Substitute these values into equation 1
- n = (24×20×2)/(4×4×2)
- n = 30
Hence, The number of blocks of clay needed by Hyla is 30 blocks
