A building has 4 stories that are each 15 feet high. A scale drawing has the height of the building at 5 inches.
Which of the following is the correct scale?
1:72
1:12
1:144
5:60
Answer:
1:144
Step-by-step explanation:
if each floor is 15 feet, the whole building is 60 feet tall. so it does have a scale of 5 inches:60 feet but if you simplify that, its 1 inch: 12 feet, so you convert feet into inches by multiplying by twelve, which gives you a scale of 1:144 inches
Answer:
1:144 inches
Step-by-step explanation:
y = 1/2x - 4 Slope: X-intercept: Y-intercept:
Answer:
Slope = [tex]\frac{1}{2}[/tex] , X-intercept = 8 , Y-intercept = -4
Step-by-step explanation:
the following equation is given in slope intercept form which is y = mx + b where m is the slope and b is the y intercept
since m = [tex]\frac{1}{2}[/tex] and b = -4, we can say our slope is [tex]\frac{1}{2}[/tex] and y intercept is -4.
Recall that x intercept occurs when y = 0 so plug y = 0 in the equation then solve for x
0 = [tex]\frac{1}{2}[/tex]x - 4
add 4 to both sides,
4 = [tex]\frac{1}{2}[/tex]x
multiply by 2 on both sides,
4*2 = x
8 = x
x = 8
so our x-intercept is 8
Erin buys 3 packs of potatoes costing £3 each, 3 packs of carrots for £2 per pack, and 4 turnips costing 60p each.
If she pays with a £20 note, how much change would she get?
Answer:
£2.6
Step-by-step explanation:
Given data
3 packs of potatoes costing £3 each= 3*3= £9
3 packs of carrots for £2 per pack= 3*2= £6
4 turnips costing 60p each= 4* 0.60= £2.4
Hence the total cost = 9+6+2.4= £17.4
Hence the change will be 20-17.4
= £2.6
Describe the transformation that maps the pre-image (ΔA) to the image (ΔA').
A) a rotation 180° clockwise around the origin
B)a rotation 270° clockwise around the origin
C)a rotation 90° counterclockwise around the origin
D)a rotation 270° counterclockwise around the origin
The transformation that maps the pre-image (ΔA) to the image (ΔA') will be done by a rotation 90° counterclockwise around the origin. Then the correct option is C.
What is a transformation of geometry?A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.
Rotation does not change the size and shape of the geometry.

El triplo de la suma de dos números es 63, y el número mayor es 6 veces el menor. Entonces, el número mayor es?
x: número más grande
y: número menor
3 (x + y) = 63
x = 6 años
Sustituimos la x = 6y de la segunda ecuación en la primera
3 (6 años + años) = 63
7 años = 63/3
3 años = 21
y = 21/7
y = 3
Este es el número más pequeño y = 7, por lo que el número más grande es x = 6y = 6 * 3 = 18
El número más grande es 18

[tex]\frac{2y-1}{15} =\frac{y}{10}[/tex]
Answer:
y = 2
Step-by-step explanation:
Given
[tex]\frac{2y-1}{15}[/tex] = [tex]\frac{y}{10}[/tex] ( cross- multiply )
10(2y - 1) = 15y ← distribute left side
20y - 10 = 15y ( subtract 15y from both sides )
5y - 10 = 0 ( add 10 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2

Katie blows up a balloon and ties it so there is a fixed amount of air in the balloon.
She wraps a piece of string around the widest part of the balloon, and measures it to find the size of the balloon. She has access to:
- A freezer
- A warm cupboard
- A cold refrigerator
- A normal temperature classroom.
How does the temperature affect the size of a blown up balloon?
PLZ ANSWER AND HELP ME!!!!!!!!!!!!!
Answer:
According to Charles' Law the order of arrangement of the location where the balloon has the smallest size to the location where the balloon has the largest size is given as follows;
A freezer < A cold refrigerator < A normal room temperature classroom < A warm cupboard
Step-by-step explanation:
The parameter of the balloon Katie blows are;
The amount of air in the balloon = Fixed (constant)
The initial size of the balloon = The length of the measured string
The locations in which the balloon can be placed = A freezer, a warm cupboard, a cold refrigerator, a normal temperature classroom
The size of the balloon is given by the volume of the balloon
according to Charles' Law, the volume of a given mass of gas is directly proportional to its temperature
Mathematically, Charles law can be expressed as follows;
V ∝ T
Therefore, as the temperature to which the balloon is subjected decreases, the volume decreases
The locations arranged in order of increasing temperature is given as follows;
Freezer < Cold refrigerator < Normal temperature classroom < Warm cupboard
Given that Katie blow's the balloon in a normal temperature classroom, according to Charles Law, we have;
The temperature of the air in the balloon decreases largely in a freezer, therefore, the size of the balloon largely decreases
The temperature of the air in the balloon increases in a warm cupboard, therefore, the size of the balloon increases
The temperature of the air in the balloon decreases slightly in a cold refrigerator, therefore, the size of the balloon decreases
The temperature of the air in the balloon remains the in a normal temperature classroom, therefore, the size of the balloon remains the same
The size of the balloon reduces the most in a freezer
The size of the balloon increases in a warm cupboard
The size of the balloon decreases slightly in a cold refrigerator
The size of the balloon remains the same in a normal temperature classroom.

Answer:

Step-by-step explanation:
The right triangle is isosceles, so x = 45° and tan(x) = 1.
__
You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.
