Mirna earned $145 baby-sitting during the spring break. She needs to save $105 for the German Club trip. She wants to spend the remainder of the money shopping. Use s for the amount of money Mirna can spend. Enter your inequality in the most simplified form.
Answer:
$145 - $105 ≤ $40
Step-by-step explanation:
Amount earned = $145
Amount to save = $105
Amount to spend, s = $145 - $105
= $40
The inequality is
Amount earned - Amount to save ≤ Amount to spend
$145 - $105 ≤ s
$145 - $105 ≤ $40

Yasmin purchased 6 heads of cabbage that each weighed 2 and StartFraction 3 over 8 EndFraction pounds. How much did the cabbage weigh all together? 9 and three-fourths pounds
Answer:
Step-by-step explanation:
Amount of cabbage bought = 6 heads of cabbage
Weight of one cabbage = 2 3/8 pounds
6 cabbage will weight x pounds
Use the equality postulate to find x:
1 cabbage = 19/8 pounds
6 cabbages = x pounds
Cross multiply
1 * x = 6 * 19/8
x = 114/8
x = 14 2/8
x = 14 1/4
Hence the cabbage altogether will weight 14 1/4 pounds
Whats the midpoint between 1 and 2
Answer:
1.5
Step-by-step explanation:
Think of a number line, on the number line are the points 1 and 2, the number between those points is the midpoint.
You can also average 1 and 2 to get the midpoint. To average any number sequence, simply add all of the numbers and then divide the sum of those numbers by the amount of numbers there are.
In this case add 1 and 2 to get 3 then divide 3 by 2 (because there are two numbers) to get 1.5
The midpoint between 1 and 2 is 1.5.
What is the midpoint?A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.
Given points are 1 and 2. The midpoint is calculated by using the formula as ( x₁ + x₂ ) / 2.
Average 1 and 2 to get the midpoint. To average any number sequence, simply add all of the numbers and then divide the sum of those numbers by the number of numbers there are.
The midpoint will be calculated as:-
M = ( x₁ + x₂ ) / 2.
M = ( 1 + 2 ) / 2.
M = ( 3 ) / 2.
M = 1.5
Therefore, the midpoint between 1 and 2 is 1.5.

target sells 24 bottles of water for $3, and 36 of water for $4 witch is the better buy and by how much
Answer:
36 bottles for $4
Step-by-step explanation:
First you need to calculate the price for one bottle, the lower the cost, the better buy. Do this by dividing the price by the amount of bottles:
= $3 ÷ 24
= 0.125 cents
= $4 ÷ 36
= 0.111 cents
The cheaper option and the better buy is the 36 bottles for $4.
A quantity of 22% acid solution is being diluted with some 8% acid solution. The final solution must be 12% acid and contain 101 mL. How much of each solution must be added to achieve the result? ROUND TO THE NEAREST mL.
Answer:
Amount of 22% acid solution needed = 29 ml
Amount of 8% acid solution needed = 72 ml
Step-by-step explanation:
Let x=amount of 22% solution needed
Then 101 - x= amount of 8% solution needed
The pure acid in the 22% solution (0.22x) plus the amount of pure acid in the 8% solution 0.08(101 - x) has to equal the amount of pure acid in the final mixture (0.12*101).
The equation to solve is:
0.22x + 0.08(101 - x) = (0.12*101)
0.22x + 8.08 - 0.08x = 12.12
0.14x = 12.12 - 8.08
0.14x = 4.04
x = 4.04 / 0.14
= 28.86
x = 29 ml to the nearest ml
Amount of 22% acid solution needed = 29 ml
Amount of 8% acid solution needed = 101 - x
= 101 - 29
= 72ml

Answer: x^2+3x+5
Step-by-step explanation:
Substitute (x+4) in so that you get f(x)=(x+4)^2-5(x+4)+9. Then expand so you get x^2+8x+16-5x-20+9. Now simplify and you get x^2+3x+5. That is your final answer.

Answer:
[tex]h(t) = -5(t-2)^2+20[/tex]
20 meters
Step-by-step explanation:
The vertex form of the equation is h(t) = -5(t-2)^2 - 4 and the ball was 20 meters above the ground
Vertex form of an expressionThe standard vertex form of a quadratic equation is expressed as (a-h)^2 + k
Given the height of the ball (in meters above the ground) t seconds after Sara kicked it is modelled by h(t)=-5t^2+20t
Write in vertex form
h(t)=-5t^2+20t
h(t) = -5(t^2 - 4t)
h(t) = -5(t^2 - 4t + 2^2) - 2^2
h(t) = -5(t-2)^2 - 4
Hence the vertex form of the equation is h(t) = -5(t-2)^2 - 4
At the highest point t = -b/2a
t = -20/2(-5)
t = -20/-10
t = 2ssecs
Substitute t = 2 into the function
h(2) = -5(2)^2 + 20(2)
h(2) = -20 + 40
h(2) = 20 meters
Hence the ball was 20 meters above the ground
