Answer:
[tex]\dfrac{5}{8}[/tex] butter was left after she was done baking.
Step-by-step explanation:
Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking.
We need to find how much butter was left after she was done baking.
It can be calculated as follows,
Left =
[tex]=\dfrac{7}{8}-\dfrac{1}{4}\\\\=\dfrac{7}{8}-\dfrac{2}{8}\\\\=\dfrac{7-2}{8}\\\\=\dfrac{5}{8}[/tex]
Hence, [tex]\dfrac{5}{8}[/tex] butter was left after she was done baking

Answer:
y<-2x-3
Step-by-step explanation:
Your first step is to find the equation of the line. You can see that the y-intercept is -3, therefore your b is -3. So now your formula looks like this:
y=mx-3
To find m, you substitute in an x value and its corresponding y value. When you do this you will get -2.
Now it looks like this:
y=-2x-3.
Now that you have the equation of the line, you can look at the inequality. Since the line is dotted, that means it is not included in the inequality. That mean it cannot contain an equal to. So the only options we have are < and >. Since the shaded area is to the left, which is the negative side, we can conclude that y<-2x-3 is the correct equation.
HOPE THAT THIS IS HELPFUL!

The wildflowers began blooming by my house at the beginning of March. The first week there were 88 blooms. After week two, there were 176 flowers in bloom. If the flowers continue to bloom at the same rate each week, how many flowers will there be after 6 weeks?
Answer:528
Step-by-step explanation:
This one is just like the other one but different numbers. if you add 88 and 88 you get 176 so that means 88 blooms each week soooooo if you multiply 88 x 6 you would get 528

Write an equation of a line that passes through the point (-2,3) and is perpendicular to
the line x = 4
Answer:
y = 3
Step-by-step explanation:
x = 4 has an undefined slope meaning on a graph the line is vertical. In order to form a line perpendicular to this, we need a line with zero slope (horizontal line). We need to look strictly at the y coordinate to help determine the equation. In this case, we have a y coordinate of 3. Therefore, the equation will be y = 3.
Can someone please help me with this question.
Answer:
Since FAB and GED are congruent they also create the same angle. The angle is shown with the curved line. AE is a straight line, or 180 degree angle. This means that FAB and ABC must create a 180 degree angle... and if FAB is congruent to GED then GED and EDC are also congruent.

Step-by-step explanation:
2x+4y=0 y=1/2x-3 solve for x
Answer:
There are 2 equal signs in this equation there is no way to solve it if there are 2 equal signs
Step-by-step explanation:
Answer:
x = 1/3
Step-by-step explanation:
2x + 4y = 0
y = 1/2x - 3
substitution method: 2x + 4(1/2x - 3) = 0
2x + 2x - 4/3 = 0
4x = 4/3
12x = 4
x = 4/12 or 1/3

Answer:
[tex]\frac{log(x + 2)}{log4}[/tex] is the correct answer
Step-by-step explanation:
The formula for change of base in logarithm is given by,
[tex]logba = \frac{logc a}{logc b}[/tex]
If we take the common base as 'e' , the formula becomes,
[tex]logba = \frac{log a}{log b}[/tex]
Applying this formula,
[tex]log4(x + 2) = \frac{log(x +2)}{log4}[/tex]
∴ As the first option matches with our answer, hence it is the correct answer.
( In the fourth option a bracket is missing, so it is not the correct option)

What is the length of arc S shown below?
Enter an exact expression.
Answer:
The length of the arc is 1.6 cm
Step-by-step explanation:
To find the value of the length of the arc, we use the length of arc formula
Mathematically, this is;
theta/360 * 2 * pi * r
where theta is the central angle
In this case pi/4 = 180/4 = 45 degrees
r = 2 cm
So the measure of the length of the arc will be;
L = 45/360 * 2 * 22/7 * 2
= 1/8 * 4 * 22/7
= 22/7 * 1/2 = 11/7 = 1.57 cm which is approximately 1.6 cm

A 12-foot ladder is placed 4 feet away from a house as shown.
A 12 foot ladder is leaning against a house to form angle x. The distance between the house and the bottom of the ladder is 4 feet. The angle between the house and the ground is 90 degrees.
What is the value of x, rounded to the nearest degree?
x ≈
°
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.
Is this ladder being used safely?
Answer:
#1.
cos(x) = adjacent/hypotenuse = 4/12 ≈ 0.3333 ⇒ x ≈ 71°
#2
71° is between 70° and 75°, so the answer is yes, the ladder being used safely.
Step-by-step explanation:
Answer:
71
yes

A stainless steel patio heater is a square pyramid. The length of one side of the base is 24.4 in. The slant height of the pyramid is 90.4 in. What is the height of the pyramid?
Answer:
89.57in
Step-by-step explanation:
Given the following
Slant height of the pyramid l = 90.4in
Length of one side of the base b =24.4in
Required
Height of the pyramid H
To get the height we will use the Pythagorean theorem as shown
l² = h²+(b/2)²
Substitute the given values
90.4² = h²+(24.4/2)²
90.4² = h²+12.2²
h² = 90.4²-12.2²
h² = 8023.32
h = √8023.32
h = 89.57in
Hence the height of the pyramid is 89.57in
