A bag of cat food contains 4 pounds. Each serving is 1/4 of a cup. How many servings are in the bag?
Answer:
16
Step-by-step explanation:
each pound has 3.6 cups
1/4 of a pound can be multiplied
3.6 x 1/4 = 0.9
then we subtract 4 - 3.6 = 0.4 say if the question was for one pound
But we have to find 14.4 cups instead as;
3.6 x 4 = 14.4 = 4 pounds
We go back to 0.9 are first smaller serving = 1/4 cup
14.4/0.9 = 16
A ladder is leaning up against a wall with the base of the ladder only 44 feet from the wall. The ladder itself is 1414 feet long. How large is the angle formed with the ground as the ladder leans against the wall? Round your answer to the nearest tenth.
Answer:
73.4°
Step-by-step explanation:
Given that :
Base of ladder from wall = 4 feets
Length of ladder = 14 feets
Angle formed with the ground :
Using Pythagoras :
Cosine θ = adjacent / hypotenus
Adjacent = 4 feets
Hypotenus = 14 feets
Cosθ = 4 / 14
Cosθ = 0.2857142
θ = cos^-1(0.2857142) = 73.398450
= 73.4°
what is 3f + 8f + 4f simplified?
Answer:
Step-by-step explanation:
Simplifying
3f + f + 4f = 0
Combine like terms: 3f + f = 4f
4f + 4f = 0
Combine like terms: 4f + 4f = 8f
8f = 0
Solving
8f = 0
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by '8'.
f = 0
Simplifying
f = 0

Step-by-step explanation:
Write an equation in slope intercept form that is perpendicular to 3x + 2y equals 12 and passes through the point (1,2)
Answer:
The equation is y = (2/3)x + (4/3).
Step-by-step explanation:
First, you have to change the equation into slope-intecept formula to find its gradient (slope) :
[tex]3x + 2y = 12[/tex]
[tex]2y = - 3x + 12[/tex]
[tex]y = - \frac{3}{2}x + 6[/tex]
Given that when a line is perpendicular to the other line, their slope value multiplied, will form -1. Next, we have to find the slope for line :
[tex]m1 \times m2 = - 1[/tex]
[tex] - \frac{3}{2} \times m2 = - 1[/tex]
[tex]m2 = - 1 \div - \frac{3}{2} [/tex]
[tex]m2 = \frac{2}{3} [/tex]
Lastly, we have to subatitute the x and y values into the equation, to find its intercept value :
[tex]y = \frac{2}{3}x + b[/tex]
[tex]let \: x = 1,y = 2[/tex]
[tex]2 = \frac{2}{3} (1) + b[/tex]
[tex]b = 2 - \frac{2}{3} [/tex]
[tex]b = \frac{4}{3} [/tex]
[tex]y = \frac{2}{3} x + \frac{4}{3} [/tex]
y + 2x-2 = x2
y - 2x = -2

The school store sells highlighters for $1.20 and permanent markers for $1.15. On Monday they sold 8 of these
items earning a total of $9.35. How many of each item did they sell?
Answer:
3 highlighters and 5 permanent markers were sold on Monday.
Step-by-step explanation:
Since the school store sells highlighters for $ 1.20 and permanent markers for $ 1.15, there is a difference between the two products of 5 cents, or $ 0.05.
Therefore, if 8 products were sold for a total of $ 9.35, and since 1.15 x 8 equals 9.20, there is a difference of 15 cents, attributable to the highlighters, since each highlighter costs 5 cents more than the permanent markers .
Therefore, since 15/5 is equal to 3, on Monday 3 highlighters and 5 permanent markers were sold, which is corroborated by the following calculation:
3 x 1.20 = 3.60
5 x 1.15 = 5.75
5.75 + 3.60 = 9.35

Right now she has $300, and she is going to
babysit to earn $12.00 an hour. How
many
hours
will Liza need to babysit before she leaves for
college?
750 - 300 = 450
She needs to save $450 more.
$450 / $12 per hour = 37.5 hours
She needs to babysit 37.5 hours.

What is the highest common factor (HCF) of 72 and 96?
1
Answer:
HCF of 72 and 96 is 24
Step-by-step explanation:
What is the highest common factor (HCF) of 72 and 96
HCF
Highest Common factor(HCF) is the biggest number that is divisible by both numbers.
First we will write prime factors of both 72 and 96
72: 2x2x2x3x3
96: 2x2x2x2x2x3
Now, writing the common factors: 2x2x2x3
Multiplying them we get: 24
So, HCF of 72 and 96 is 24

Applying the Pythagorean Theorem Warm-up What is the value of x? 10 8
Answer:
x = 6Step-by-step explanation:
According to pythagorean theorem
a² = b² + x²
a is the hypotenuse
b and x are the opposite and adjacent
Let a = 10
b = 8
Substitute and get x:
10² = 8²+x²
x² = 10²-8²
x² = 100-64
x² = 36
x = √36
x = 6
Hence the value of x is 6
