Jacob and Melissa both collect baseball cards. Let J represent the number of cards that Jacob has. Melissa has 5 fewer cards than Jacob. Write an expression that shows how many cards they have together.
Answer: 2J - 5
Step-by-step explanation:
The number of cards that Jacob has = J
Melissa has 5 fewer cards than Jacob. Melissa card will be: = J - 5
The expression that shows the number of cards they have together will be gotten by adding their cards together. This will be:
= J + (J - 5)
= J + J - 5
= 2J - 5

A movie theater decreased the size of its popcorn bags by 20%. If the new bags hold 12 cups of popcorn, how much did the original bags hold? Nasser used the equation 0.20x = 12 Abraham used the equation 0.80x = 12 Kathleen used the equation 1.20x = 12 Decide who used the correct equation and defend your reasoning.
Answer:
Abraham
Step-by-step explanation:
Abraham used the correct equation because if we represent the original size as 100% and decrease that by 20 it would be 80% or 0.8
Nasser's equation will solve for the change in price
Kathleen's equation solves for if the popcorn size was increased by 20%
Answer:
nasser
Step-by-step explanation:
0.20 = 20/100=20%

A tree cast a 16 foot long shadow on level ground a forestry student uses a clinometer to determine the sun is that a 70° angle of elevation what is the height of the tree to the nearest whole foot
Answer:
15foot
Step-by-step explanation:
The set up will give a right angled triangle.
The length of the shadow will be the hypotenuse = 16foot
The height of the tree will be the opposite = x
The angle of elevation = 70°
Using the SOH CAH TOA trig identity
Sin theta = opposite/hypotenuse
Sin 70 = x/16
x=16sin70
x = 15.04feet
Hence the height of the tree to the nearest whole foot is 15foot

Answer:
x < -10/3 OR x > 20/3
Step-by-step explanation:
|5 - 3x| - 3 > 12
|5 - 3x| > 15
since it's absolute value, you have 2 scenarios to solve:
1) 5 - 3x > 15
-3x > 10
x < -10/3 (when dividing or multiplying by a negative, switch the symbol)
2) -(5 - 3x) > 15
-5 + 3x > 15
3x > 20
x > 20/3

The length of the base of an isosceles triangle is x. The length of a leg is 2x - 4. The perimeter of the triangle is 47. Find x.
Answer:
x = 11
Step-by-step explanation:
Remark
There are two legs. They are equal.
Equation
2x - 4 + 2x - 4 +x = 47 Combine like terms
Solution
5x - 8 = 47
5x - 8+8 = 47 + 8
5x = 55 Divide by 5
x = 11

The function can be used to determine the milligrams D of a certain drug in a patient's bloodstream h hours after the drug has been given. How many milligrams (to two decimals) will be present after
Answer: 0.09 mg
Step-by-step explanation:
To find out the milligrams in the blood after 10 hours you just need to replace the 'h' in the equation to 10.
= 5e⁻⁰°⁴ˣ¹⁰
= 5e⁻⁴
= 0.09157819444
= 0.09 mg

A dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. How many 12-inch pieces can the dressmaker cut from 10 of these rolls of ribbon?
Before you try that problem, answer the question below.
How many \textbf{inches}inches of ribbon does the dressmaker have, in total?
Answer:
60
Step-by-step explanation:
because 12 inches is one foot so there’s 6 feet per 6 feet of ribbon and there’s 10 of these ribbons so 6 times 10 is 60
The 12-inch pieces the dressmaker can cut from 10 of these rolls of ribbon will be 60 strips .
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that the dressmaker has 720 inches of ribbon.
dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length.
The amount of rolls she has = 10 rolls
so,
6(strips per roll) x 10(amount of rolls) = 60 strips

Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet 1. Find the time in Devon which the ball reaches it maximum height
Answer: 4 seconds
Step-by-step explanation:
Given: The function [tex]h(t)=-36t^2+288t+9[/tex] can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get
[tex]h'(t)=-36(2)t+288=-72t+288[/tex]
Put h'(t)=0
[tex]\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4[/tex]
Also, [tex]h''(t)=-72<0[/tex]
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
