step 2
The new scale drawing is
[tex]\frac{1}{180}[/tex]
That means
1 unit in the drawing represent 180 units in the actual
or
1 inch in the drawing represent 180 inches in the actual
step 3
Find the length of a new scale drawing
using proportion
[tex]\frac{1}{180}=\frac{x}{960}\\\\x=960/180\\\\x= 5.33\ in[/tex]
Convert to mixed number
[tex]5.33\ in=5\frac{1}{3}\ in[/tex]
The actual length of the house if the scale is 1/80 is = 5 1/3 inches
What is a scale drawing?A scale drawing is a reduced form in terms of dimensions of an original image / building / object
Scale of the drawing = dimensions of the scale drawing / dimensions of the original image.
Actual length when the scale was 1/80 = 80 x 12 = 960 inches
Actual length when the scale was 1/180 = 960 / 180 = 5 1/3 inches

predicts the height, in meters of an object t seconds after a person launches it into the air.
It will take _ seconds for the object to hit the ground.
Answer:
8 seconds
Step-by-step explanation:
Given
h = - 5t² + 40t
When the object hits the ground then h = 0
Substitute h = 0 into the function and solve for t
- 5t² + 40t = 0 ← factor out - 5t from each term
- 5t(t - 8) = 0
Equate each factor to zero and solve for t
- 5t = 0 ⇒ t = 0
t - 8 = 0 ⇒ t = 8
t= 0 denotes the time of launch
t = 8 denotes the time it hits the ground

C = 5/9 x ( F - 32)
176*F = ?? *C
The original temperature conversion equation is Tc = 5/9 x (T-f - 32). When converting 176 degrees Fahrenheit, it is multiplied by 5/9 to get approximately 108.89 degrees Celsius.
The equation provided by the student, C = 5/9 x (F - 32), is used to convert a temperature from Fahrenheit (F) to Celsius (C). To find the factor to convert Fahrenheit to Celsius directly, we can manipulate the given formula. The request seems to be asking for the conversion factor that is applied to Fahrenheit to get Celsius. However, the original equation needs to be rewritten correctly as: TC = (5/9) × (T-F - 32). From this, we infer that each degree Fahrenheit is equivalent to 5/9 of a degree Celsius. Therefore, 176°F would convert to 176 × (5/9) = 980/9 or approximately 108.89°C.

find the values of a and b such that x^4 +ax^3 -7x^2 - 8x +b is exactly divisible by(x+2) and (x+3)
Answer:
a = 2 ; b = 12
Step-by-step explanation:
p(x)=x⁴ + ax³ - 7x² - 8x +b
p(x) is exactly divisible by (x + 2). So p(-2)=0
(-2)⁴ + a(-2)³ - 7(-2)² - 8(-2) +b = 0
16 - 8a - 7*4 +16 + b =0
16 - 8a - 28 + 16 + b =0
4 - 8a + b = 0
-8a + b = -4 -----------(i)
p(x) is exactly divisible by (x + 3). So p(-3)=0
(-3)⁴ + a(-3)³ - 7(-3)² - 8(-3) +b = 0
81 -27a - 63 + 24 + b =0
42 - 27a + b = 0
-27a + b = -42 ------------(ii)
-8a + b = -4 -----------(i)
-27a + b = -42 ------------(ii)
subtract 19a = 38
a = 38/19 = 2
a=2
Substitute a value in equation (i)
-8*2 + b= -4
-16 + b = -4
b = -4 + 16
b = 12

When writing numbers in words you always want to go from left to right, the last three of your digit was in the hundreds place, then the next three were in the thousands place, than the millions, then the billions, and last was the trillions which is where we got five trillion to start out with, you next number was two hundred and ninety billion, because your next place value was in the billions.
When writing numbers using scientific notation you always want just one number to the left of the decimal point. When adding a decimal we put it right after the 5 because then we only have one number in front of the decimal point. Then you would go times 10 to the whatever power it is. In our case it was 12 because you go from your decimal point and count backwards til you get to the correct number that you want

Tina owns a florist shop. She charges 2.99 cents for each flower plus a delivery fee of 5.
y=_____________, only type what goes in the blank.
Answer:
Charges per flower delivered by Tina is, y= 2.99 (x) + 5
Step-by-step explanation:
Given:
Tina's charges per flower = 2.99 cents
Delivery charged by Tina = 5 units or 5$
We have fill the blank in terms of 'y'.
We know slope intercept form that is : y = m(x)+b
So here we have to fill numbers according to the slope intercept form.
Let the numbers of flowers sold by Tina be 'x'.
Here slope (m) will be the charge of each flower charged by the florist.
The delivery charge is the fixed rate so its the constant value and will be treated equivalent to y-intercept or b values.
Arranging our values:
[tex]m=2.99[/tex] cents , [tex]b=5\$[/tex]
Then the slope-intercept form :
⇒ [tex]y=m(x)+b[/tex]
⇒ [tex]y= 2.99(x) + 5[/tex]
