Luis and Jasmine are making scale drawings of the front of their school for an art contest. Luis uses the scale 3 in. to 10 ft. Jasmine uses the scale 5 in. to 20 ft. The tree in front of the school in Luis's drawing is 7.5 inches tall. How tall is the tree in Jasmine's drawing?
The height of the tree in Jasmine's scale drawing is 6.25 inches.
What is the height of the he tree in Jasmine's scale drawing?A scale drawing is a smaller version of a larger image or drawing. The scale drawing is usually reduced at a constant dimension
Scale of the drawing = original dimensions / dimensions of the scale drawing
The first step is to determine the original height of the tree:
Height of the tree from Luis' scale drawing = (7.5 x 10) / 3 = 25 ft
Height of the tree in Jasmine's scale drawing = (5 x 25) / 20 = 6.25 inches

When a number is decreased by 10% of itself, the result is 27. What is the number? Write an equation to model the problem
Answer: [tex]x-0.1x=27[/tex]
Step-by-step explanation:
Let x be the number that gets decreased by 10% of itself.
x decreased by 10% of x is 27.
x is 100%, so 100%-10%=90%
So, 90% of x equals 27.
90% = 0.9
0.9x = 27
x = 30

The simplified fraction is -2 1/4
FractionsFrom the question, we are to evaluate the given fractions
The given fraction is
[tex]-1\frac{4}{5} + (-\frac{1}{4}) + (- \frac{1}{5} )[/tex]
Evaluating the fraction
[tex]-1\frac{4}{5} + (-\frac{1}{4}) + (- \frac{1}{5} )[/tex]
First, convert the mixed fraction to an improper fraction
[tex]-\frac{9}{5} + (-\frac{1}{4}) + (- \frac{1}{5} )[/tex]
Now, clear the parentheses
[tex]-\frac{9}{5} -\frac{1}{4}- \frac{1}{5}[/tex]
Find the LCM of the denominators
The LCM is 20
Thus,
[tex]\frac{-36 - 5 - 4}{20}[/tex]

60°, 45°, and 70°
30°, 85°, and 25°
55°, 90°, and 35°
110", 15°, and 45°
Answer:
(c) 55°, 90°, and 35°
Step-by-step explanation:
Given lists of angle measures, you want to know which could be the interior angles of a triangle.
Angle sum theoremThe angle sum theorem tells you the sum of interior angles of a triangle is 180°. To find the angles that could be those of a triangle, check to see if their sum is 180°.
a) 60 +45 +70 = 175 ≠ 180
b) 30 +85 +25 = 140 ≠ 180
c) 55 +90 +35 = 180 . . . . . . . could form a triangle
d) 110 +15 +45 = 170 ≠ 180
The angle measures 55°, 90°, and 35° could be the interior angles of a triangle.

Find WX. Figure is not drawn to scale.
Answer:
37
Step-by-step explanation:
WX = a
XY = a-9
WY = WX + XY = 65
So we substitute values:
WY = a + a -9 OR 2a - 9
65 = 2a -9
Then we collect like terms:
2a = 65 + 9
2a = 74 (divide both sides by 2 to get a)
a = 37

6x + 3y + 62 = 6
3x + 41 + 42 = 9
Answer:
x=-1
y=2
z=1
Step-by-step explanation:
After substitution we add common terms and make y and z the subject
y= 3-z
z= - 3+ 2y
We substitue the y
z = - 3+2(3-z)
z= 1
and now we subtitute the z to find y
y= 3-z
3-1 = 2
y=2
Now we substitue y and z to find x
x= - 2 - 3/2 + 5/2
x= - 1

Vectors are represented by an alphabet with an arrow over it (or) by an alphabet written in bold. Vector addition can be used to combine two vectors, a and b, and the resultant vector is written as a + b. Before we can learn about the properties of vector addition, we must first understand the conditions that must be met when adding vectors. The following are the terms:
Vectors can only be added if they are of the same type. For example, acceleration should only be added with acceleration and not mass.

1. A scale drawing of a school bus has a scale of 1/2 inch to 5 feet. If the length of r
the school bus is 4 1/2inches on the scale drawing, what is the actual length of the bus
The length of the school bus is 45 feet.
Given, School bus has a scale of 1/2 inch to 5 feet.
Length of the school bus is 4 1/2 inches on the scale drawing.
Actual length of the bus = ?
Given scale = 1/2 inch = 5 feet
⇒ 1 inch = 1/2 inch ₊ 1/2 inch
⇒ 1 inch = 5 feet ₊ 5 feet
⇒ 1 inch = 10 feet
Length of school bus = 4 1/2 inches = 4.5 inches.
Actual length:
length of school bus = length in inches × length in feet
4.5 inches = (4.5 × 10) feet
4.5 inches = 45 feet.
Hence we get the actual length of the school bus as 45 feet.

The scatter plot shows prize money, in thousands of dollars, for a contest over eight consecutive years.
Predict the amount of prize money in year 10 of the contest.
$11,790
$20,340
$35,200
$45,900
Building a regression line from the scatter plot, it is found that the predicted prize money in year 10 of the contest is of: $11,790.
How to find the equation of linear regression using a calculator?To find the equation, we need to insert the entire set of points (x,y) given by the scatter plot in the calculator.
From the scatter plot, the points are approximated as follows:
(1, 9.5), (2,9), (3,7), (4,10), (5,11), (6, 10), (7, 10.5).
With the help of a calculator, the line of best fit to predict the amount of prize money in year x of the contest is given by:
P(x) = 0.32143x + 8.28571
To find the predicted amount in year 10, we have to find the numeric value when x = 10, hence:
P(10) = 0.32143(10) + 8.28571 = $11,500.
The closest option is $11,790, which is different from $11,500 because the coordinates of the points are approximated from the scatter plot and not exact.
