Answer:
Food bags - 175, pet blankets - 70, dog toys - 35Step-by-step explanation:
Given:
Dog food bags - f, cost of each $8, Pet blanket - b, cost of each $5Dog toy - t, cost of each $4Total cost $1890Equations:
8f + 5b + 4t = 1890f = 5tb = 2tSubstitute values of b and t into first equation and solve for t:
8(5t) +5(2t) + 4t = 189040t + 10t + 4t = 189054t = 1890t = 1890/54t = 35Find the values of f and b:
f = 5*35 = 175b = 2*35 = 702 iPhones cost $1,680, how much would 10 iPhones cost?
Answer:
$8,400
Step-by-step explanation:
one way to solve it would be that since you know 2 x 5 = 10 you can do $1,680 x 5 and that = $8,400
4952 rounded to the nearest ten
Answer:
4950
Step-by-step explanation:
4952 has:
'4' in the thousands place
'9' in the hundreds place
'5' in the tens place
'2' in the ones place
Rounding to the nearest tens means to look at the value in the ones place and if it is 5 or greater the value in the tens place increases by one, otherwise it remains the same
Suppose y varies jointly as x and z. What is y when x = 2 and z = 3, if y = 20 when x = 4 and z = 3?
Answer:
y = 10
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 20 when x = 4 and z = 3 , then
20 = k × 4 × 3 = 12k ( divide both sides by 12 )
[tex]\frac{20}{12}[/tex] = k , that is
k = [tex]\frac{5}{3}[/tex]
y = [tex]\frac{5}{3}[/tex] xz ← equation of variation
When x = 2 and z = 3 , then
y = [tex]\frac{5}{3}[/tex] × 2 × 3 = 5 × 2 = 10

Miss Reyes earns $3500 per month from which income tax is deducted at 30%. Calculate her net pay.
Answer: 3395 dollars
Step-by-step explanation:
First, the question said that Miss Reyes earns 3500 dollars. But the tax is 30%. Than, the tax is 3500 times to 30%. If you calculate it, it will be 105 dollars. Now, we can subtract the 105 from 3500. It equals to 3395 dollars.
What is the perimeter of the L-shaped figure?
Please answer without using a link.
Answer:
3a+4+4+6+2a
5a+14
Step-by-step explanation:
hope i got it right
Step-by-step explanation:
we know,
perimeter = sum of all sides
so a/q perimeter of the given figure is
→ 3a + 4 + 4 + 6 + a + 4 + 2 + 2a
→ 6a + 20
therefore, perimeter of the given figure is 6a + 20.

Sergei buys a rectangular rug for his living room. He measures the diagonal of the rug to be 18 feet. The length of the rug is 3 feet longer than the width. What are the approximate dimensions of the rug? Round each dimension to the nearest tenth of a foot. 10. 4 feet by 7. 4 feet 11. 1 feet by 8. 1 feet 13. 4 feet by 10. 4 feet 14. 1 feet by 11. 1 feet.
A rectangular rug divided by its diagonal becomes a right angle triangle
The length and width of the rug is 14.1 feet by 11.1 feet
A right angle triangle has the longest side as the hypotenus which is also the diagonal.Diagonal = 18 feet
width = x
length = x + 3
diagonal ² = length ² + width ²
18² = x² + (x + 3)²
18² = x² + x² + 6x + 9
324 = 2x² + 6x + 9
2x² + 6x + 9 - 324 = 0
2x² + 6x - 315 = 0
solve using quadratic formula
x = - b ± √b² - 4ac / 2a
= - 6 ± √6² - 4×2×-315 / 2×2
= -6 ± √36 - (-2520) / 4
= -6 ± √36 + 2520/4
= -6 ± √2556 / 4
= - 6 ± 6√71 / 4
= -6/4 ± 6√71 / 4
= -3/2 ± 3√71/2
x = 11.1392 or -14.1392
The value of x can't be negative
So,
x = 11.1 to the nearest tenth
Therefore, the value of width and length is
width = x
= 11.1 feet
length = x + 3
= 11.1 + 3
= 14.1 feet

For which values of x does each expression make sense? √(-2x)^2
We want to see for which values of x does the rational expression make sense. We will see that the expression makes sense for x ≤ 0
We know that the argument of a square root can only be a real number equal to or larger than zero.
In this case, we have the expression:
[tex]\sqrt{(-2x)^2} = (\sqrt{-2x} )^2[/tex]
One would want to directly cancel the square root with the 2 exponent, but we can't do that, because in the right-side expression we would have a complex number if the argument is smaller than zero.
The first thing we need to do is to make the argument equal or larger than zero:
-2x ≥ 0
x ≤ 0/-2
x ≤ 0
So the given expression only makes sense for x ≤ 0

A line that includes the point (-1,5) has a slope of 4. What is its equation in slope-intercept
form?
Answer:
y=4x+9
Step-by-step explanation:
The slope intercept form is [tex]y=mx+b[/tex]
So m=4 and we plug it into the equation [tex]y=4x+b[/tex]
Since there are x point is -1 and y point is 5 we plug those in replacing the corresponding variables [tex]5=4(-1)+b[/tex]
So the equation becomes [tex]5=4+b[/tex]
We add 4 to both sides [tex]5=4+b\\+4=+4[/tex] so 9 equals b
Then we rewrite the whole equation as [tex]y=4x+9[/tex]

Answer:
Brett used the most
Step-by-step explanation:
Martha used = 17%
Brett used = 0.18 = 18/100 = 18%
Mike used = 0.7 × 100/8 = 8.75% (he only used 0.7 of ONE of the gallons in the can, not of the total oil in the can)
Therefore, Brett used the greatest amount of oil.
