The dry ingredients in a chocolate cake recipe are 2 cups of flour, 3/2 cups of sugar, and 3/4 cup of cocoa. How many cups of dry ingredients are in the cake mix?
Answer: There are four and one-fourth cups of dry ingredients are in the cake mix.
Step-by-step explanation:
Given: Quantities of dry ingredients for cake:
2 cups of flour, [tex]\dfrac32[/tex] cups of sugar, and [tex]\dfrac34[/tex] cup of cocoa.
Total cups of ingredients used = [tex]2+\dfrac32+\dfrac34[/tex]
[tex]\dfrac{2\times4+3\times2+3}{4}\\\\=\dfrac{8+6+3}{4}\\\\=\dfrac{17}{4}\\\\=\dfrac{16+1}{4}\\\\=4\dfrac14\text{ cups}[/tex]
Hence, there are four and one-fourth cups of dry ingredients are in the cake mix.

Answer:
? is 24
Step-by-step explanation:
Answer:
? = 24
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{?}{18}[/tex] = [tex]\frac{20}{15}[/tex] ( cross- multiply )
15? = 360 ( divide both sides by 15 )

The town of gettysburg, PA, plans to shoot a live cannon as part of their annual Gettysburg Civil War Battle Reenactment. The organizers want to make sure that when they fire the cannon, it lands in a location that does not injure any participants or spectators. The slope of the field they are firing into can be represented by the equation y=0.15x. Let x represent horizontal distance, and y represents vertical distance.. if the cannon fires the cannon ball at an arc denoted by the equation y=-0.5x^2+2.5x+1, at what distance will the cannonball land.
-I know i'm supposed to set -0.5x^2+2.5x+1=.15x and use distance formula BUT I KEEP GETTING DIFFERENT ANSWERS.
Answer:
The cannonball lands at approximately 5.093 unit distance from the point of fire
Step-by-step explanation:
The given parameters are;
The arc denoting the equation of motion of the cannon is y₁ = -0.5·x² + 2.5·x + 1
The slope of the field where in the direction the cannon is fired is y₂ = 1.5·x
The points where the cannonball land on the slopping field is given as rightly pointed by equating the two equations, the cannonball path path and the field path as follows;
At the point of contact of the cannonball and the field, the y-values of both equation will be equal
y₁ = y₂
∴ -0.5·x² + 2.5·x + 1 = 0.15·x
Which gives;
-0.5·x² + 2.5·x - 0.15·x + 1 = 0
-0.5·x² + 2.35·x + 1 = 0
-(-0.5·x² + 2.35·x + 1) = 0.5·x² - 2.35·x - 1 = 0
0.5·x² - 2.35·x - 1 = 0
The above equation is in the general form of a quadratic equation, which is given as follows;
a·x² + b·x + c = 0
By the quadratic equation, we have;
[tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex]
Plugging in the values, gives;
[tex]x = \dfrac{2.35\pm \sqrt{(2.35)^{2}-4\cdot (0.5)\times (-1)}}{2\cdot (0.5)} = \dfrac{2.35\pm \sqrt{7.5225}}{1} =2.35 \pm \sqrt{7.5225}[/tex]
∴ x ≈ 5.093 or x ≈ -0.393
Therefore, the cannonball will takeoff at x ≈ -0.393 and land at x ≈ 5.093
The height from which they fire the cannon is given by the substituting the value of x ≈ -0.393 into the equation for the path of the cannonball, to give;
[tex]y_{(initial)}[/tex] = -0.5·(-0.393)² + 2.5·(-0.393) + 1 = -0.0597
[tex]y_{(initial)}[/tex] ≈ -0.0597.
However, the actual initial height from which the cannonball is fired given by placing x = 0, which gives y = 1, which is the reason for the other (negative) value for x. Please see the attached graph created with Microsoft Excel.

Let H(x) be the percent of U.S. households with Internet use x years after 1980. Match each statement with its meaning.
1. H(23)=55
2. H(4)=k
3. H(27)≥61
4. H(17)+H(21)≈H(29)
Options-
(in the picture)
Answer:
H(23)=55 - 55% of U.S households had internet use in 2003.
H(4)=k - k% of U.S households had internet use in 1984.
H(27)≥61 - At least 61 percent of U.S households had internet use in 2007.
H(17)+H(21)≈H(29) - The sum of the percents of U.S. households with internet use in 1997 and 2001 is about the same as the percent of U.S. households with internet use in 2009.
Step-by-step explanation:
I have no idea how to explain, oh well.
From the function, the correct interpretations are:
1. 55% of U.S. households had internet use in 2003.
2. k% of U.S. households had internet use in 1984.
3. At least 61% of U.S. households had Internet use in 2007.
4. The sum of the percents of U.S households with Internet use in 1997 and 2001 is the same as the percent of U.S households with Internet use in 2009.
---------------------------
The function H(x) represents the percentage of households with Internet in x years after 1980, thus x is the number of years after 1980 and H(x) is the percentage of households with internet in year 1980 + x.
1. H(23)=55
1980 + 23 = 2003, thus 55% of U.S. households had internet use in 2003.2. H(4)=k
1980 + 4 = 1984, thus k% of U.S. households had internet use in 1984.3. H(27)≥61
1980 + 27 = 2007, thus: At least 61% of U.S. households had Internet use in 2007.4. H(17)+H(21)≈H(29)
Following the same logic as previous items, as considering that the output is a percentage: The sum of the percents of U.S households with Internet use in 1997 and 2001 is the same as the percent of U.S households with Internet use in 2009.A similar problem is given at https://brainly.com/question/24242199

Using Angle Side Relationship Theorem, use the side measures to list the angle measures of the triangle in order from biggest to smallest.
Q
R
P
Answer:
∠Q, ∠P, ∠R
From largest to smallest.
Step-by-step explanation:
Remember that the largest side is always opposite from the largest angle.
26 is the longest side. The angle opposite is 26 is ∠Q. So, ∠Q is the largest angle.
21 is the second longest side. ∠P is the angle opposite to 21. So, ∠P is the second largest angle.
Finally, 17 is the shortest side and ∠R is opposite to 17.
So, ∠R is the smallest angle.
Therefore, the measures of the angles from biggest to smallest is:
∠Q, ∠P, ∠R

8a+5 = 7b+4 = 5c + 2
Answer:
a= -5/8
b= -4/7
c= -2/5
Step-by-step explanation:
8a + 5 = 7b + 4 =5c + 2
I'm not sure what you want with this incomplete question, but I assume it's to find the values of a, b, and c.
Therefore, to find the value of a,
8a+5=0
8a= - 5
a= -5/8
7b + 4=0
7b = - 4
b= -4/7
5c + 2=0
5c= - 2
c= -2/5
Therefore, the values of a, b, and c are -5/8, -4/7 and -2/5
