A fruit market must spend less than $225 for an order of apples and oranges. A pound of apples costs $0.50 and a pound of oranges costs $0.75. This relationship is shown in the graph. The market needs at least 50 more pounds of apples than oranges. Which choice is a reasonable solution?
Answer:
Oranges :100 pound
Apples : 250 pound
Step-by-step explanation:
A fruit market must spend less than $225 for an order of peaches and mangoes. A pound of peaches costs $0.50 and a pound of mangoes costs $0.75. This relationship is shown in the graph. The market needs at least 50 more pounds of peaches than mangoes. Which choice is a reasonable solution?
=========
0.5p + 0.75m <= 225
p = m + 50
-------------------
Substitute for "p" and solve for "m"::
0.5(m+50) + 0.75m <= 255
0.5m + 25 + 0.75m <= 255
2.25m <= 325
---
m <= 144.44
--------------------
# of oranges : 100 pound
# of pound of apples: m+50 = 250 pound
Hope you understand :)
Pls mark me as brainiest
Answer:
Answer choice C should be more Resonable.
Step-by-step explanation: It is very obvious
because you are spending less than $225 and when it says at least 50 more it means that 50 is the bare minimum so the ideal choice is 150 more apples than oranges and likely the oranges will be 100 and aples will be 250 and you won't spend over $225.
Over time, the value of a car decreases. If the value of a car purchased for Php
1,250,000 decreases to Php 1,000,000 throughout a year, what is the rate of change?
Answer:
-20%
Step-by-step explanation:
Current value of an item and divide it by the value from an earlier period. Subtract one and multiply the resulting number by 100 to give it a percentage representation.
ROC = (current value/previous value − 1) x 100
ROC = (1,000,000/1,250,000 - 1) x 100
ROC = (0.8 - 1) x 100
ROC = -0.2 x 100
ROC = -20

if sinA=1/2 then find sinA +cos A
Step-by-step explanation:
Given sinA – cosA = 1/2 squaring on both the sides, we get (sinA – cosA)2 = (1/2)2 ⇒ sin2A + cos2A – 2sinA cosA = 1/4 ⇒ 1 – 2sinA cosA = 1/4 ⇒ 1 – (1/4) = 2sinA cosA ⇒ 2sinA cosA = 3/4 ∴ sinA cosA = 3/8 → (1) (sinA + cosA)2 = (sinA – cosA)2 + 4sinA cosA = (1/2)2 + 4(3/8) = (1/4) + (3/2) = 7/4 (sinA + cosA) = √(7/4) = (√7)/2 .
Given that,
[tex]\sin A = \dfrac 12\\\\ \implies \sin^2 A = \dfrac 14\\\\\ \implies 1-\cos^2 A = \dfrac 14\\\\\ \implies \cos^2 A = 1 - \dfrac 14 = \dfrac 34\\\\\ \implies \cos A = \pm \dfrac{\sqrt 3}2\\\\\text{Case 1:}\\\\\sin A + \cos A = \dfrac 12 + \dfrac{\sqrt 3}2 = \dfrac{1 + \sqrt 3}2\\\\\text{Case 2:}\\\\\sin A + \cos A = \dfrac 12 +\left(- \dfrac{\sqrt 3}2\right) = \dfrac 12 - \dfrac{\sqrt 3}2=\dfrac{1 - \sqrt 3}2[/tex]
Write the equation of a horizontal line going through the point (8, -1)
Answer:
y =-1
Step-by-step explanation:
An easy way to answer any type of these questions is looking at the part where it said "Write the equation of a horizontal line", if this is the case you have to look at the 2nd point given to you which is -1 and simply make y = to that. Having y = -1 covers every possible x value which is why it is valid.

Answer:
18.725
Step-by-step explanation:
4 5/8 = (4*8 + 5) /8 = 37/8
10 7/10 = (10*10 + 7) / 10 = 107/10
3 2/5 = (3*5 + 2) / 5 = 17/5
lcm of 8, 10, 5 is 40
37/8 + 107/10 - 17/5
= (37*5 + 107*4 - 17*8) / 40
= (185 + 428 + 136) / 40
= 749/40
= 18.725
(4,1),(8,2) in slope intercept form
Answer
y=1/4x
Step-by-step explanation:
2-1/8-4=1/4
Choose either of these points ( I will use 4,1 becuase it's easier)
1=1/4(4)=b
1=1+b
0=b
y=1/4x (you don't put the zero)

Interest earned in options $400 at 3% for 1 year, $400 at 3% for 1 year
and $50 at 48% for 6 months has the same interest earned by, as $150 earn 4% annual interest for 2 years.
As mentioned in the question, A certificate of deposit with a principal of $150 earns 4% annual interest for 2 years.
What is simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.
here,
1. $300 at 2% for 2 years
Simple Interest = principal × rate × time / 100
Simple interest = 300 × 2 /100 × 2
Simple interest = $12
Similarly, interest earned by other options is given as,
2. $13.5
3. $12
4. $8
5. $12
Thus, Options A, C, and E are correct.

Answer:
301/12Step-by-step explanation:
Find two numbers whose difference is 16 and whose product is a minimum. (Enter your answers as a comma-separated list.)
Answer:
8, -8
Step-by-step explanation:
Let's say that x is the larger number,
x - y = 16
y = x - 16
xy = P where P is a minimum
x(x-16) = P.
(We can find the vertex, which is the minimum, by writing it in vertex format)
Completing square:
x2 - 16x = P
x2 - 16x + 64 = P + 64
(x - 8)2 = P + 64.
So,
x = 8 and -8
(8 - -8 -> 8 + 8 = 16)

2x+4 over 3 - 5x-7 over 2 = 5 solve the equation
Answer:
x = -1/11.
Step-by-step explanation:
I am interpreting this as:
(2x+4)/ 3 - (5x-7)/2 = 5
Multiply through by the LCM of 2 and 3 ( that is 6):
2(2x + 4) - 3(5x - 7) = 30
4x - 15x + 8 +21 = 30
-11x = 30 - 21 - 8
-11x = 1
x = -1/11.
