Here is a list of numbers.
-45 -21 -16 12 33 40
(a) write down two numbers from the list that add up to -9
Answer:
-21, 12
Step-by-step explanation:
We first have to solve each of the list of numbers:
-45 -21 = -66
-21 - 16 = -37
-16+12=-4
33+40=73
-45-16=-61
-45+33 = -12
-45 + 12 = -33
-21 + 12 = -9
Hence, we can conclude that -21 and 12 add up to -9

Georgia is wrapping a shoe box with dimensions 12 x 5 x 7. What is the surface area of her box?
Answer:
358 feet²
Step-by-step explanation:
Answer:
358
Step-by-step explanation:
A= 12 x 5
= 60
x 2 = 120
A= 5 x7
= 35
x 2 = 70
A = 12 x 7
= 84
x2 =168
(I multiply by 2 because 2 sides are equall)
Add:
120 + 70 + 168 = 358

How do you write 3.5 × 10^3 in standard form?
Answer:
[tex]3500[/tex]
Step-by-step explanation:
Given the following question:
[tex]3.5\times10^3[/tex]
To convert a scientific notation into standard form we first need to keep in mind that the exponent in indeed a positive. Knowing this we know that the decimal point is going to move to the right.
Since the exponent is three, we know that the decimal point is going to move to the right THREE times.
[tex]3.5\times10^3[/tex]
[tex]3.5\times10^3=3.5.0.0.[/tex]
[tex]3.5.0.0.=3500[/tex]
[tex]=3500[/tex]
Your answer in standard form is "3500."

Find the 35th term.
Answer:
the 35th term or a(35) is 69
Step-by-step explanation:
the first thing you must do to solve this equation is to write for the nth term
this is
a(n) = 209 - 4n
i got 209 by adding 4 to 205 to find the 0th term
so to solve the equation for the 35th term oyu just plug it in
a(35) = 209 - 4(35)
a(35) = 209 - 140
a(35) = 69
Based on the length and the height you calculated, find the area of. Show your calculations.
get the question correct and you will get extra pts from a brainliest
does anyone know the answer if you do please post it here
Answer:
Step-by-step explanation:
I know gthis but its To calculate the area of a triangle, multiply the base by the height and divide by two. If you know how to calculate the area of a rectangle, you should be able to calculate the area of a triangle with ease because a triangle is half of a rectangle or square. As a result, because it's half of a rectangle, you should apply the identical approach of calculating the area of a rectangle and then dividing it by two. I hope that's clear!

A scale model of a ramp is a right triangular prism as given in this figure. In the actual ramp, the triangular base has a height of 1.2 feet. What is the surface area of the actual ramp, including the underside? Enter your answer as a decimal in the box.
The surface area of the actual ramp is 16.8 ft²
What is an area?An area is the amount of space occupied by the two dimensional shape or object.
The height of the actual ramp = 1.2 feet and the height of the model = 6 cm
Scale factor = 1.2 feet / 6 cm = 0.2 ft/cm
Actual base = 16 cm * 0.2 ft/cm = 3.2 ft
9 cm = 9 cm * 0.2 ft/cm = 1.8 ft, 10 cm = 10 cm * 0.2 ft/cm = 2 ft,
Surface area of actual ramp = 2(0.5 * 3.2 ft * 1.2 ft) + 2(2 ft * 1.8 ft) + (1.8 ft * 3.2 ft) = 16.8 ft²
The surface area of the actual ramp is 16.8 ft²
