If it takes 3/4 cups of sugar to make 1 batch of cookies, then how many cups of sugar does Fred need to make 4 or 1/2 batches?
Answer:
Fred needs 3 cups of sugar to make 4 batches
Fred needs 3/8 cups of sugar to make 1/2 batches
Step-by-step explanation:
1 batch of cookies = 3/4 cups of sugar
how many cups of sugar does Fred need to make 4 batches
Let x = cups of sugar needed
Batches : Cups of sugar
1 : 3/4 = 4 : x
1 ÷ 3/4 = 4/x
1 * 4/3 = 4/x
4/3 = 4/x
Cross product
4 * x = 3 * 4
4x = 12
x = 12/4
x = 3 cups of sugar
Fred needs 3 cups of sugar to make 4 batches
how many cups of sugar does Fred need to make 1/2 batches?
Let x = cups of sugar needed
Batches : Cups of sugar
1 : 3/4 = 1/2 : x
1 ÷ 3/4 = 1/2 ÷ x
1 * 4/3 = 1/2 * 1/x
4/3 = 1/2x
Cross product
4 * 2x = 3 * 1
8x = 3
x = 3/8 cups of sugar
Fred needs 3/8 cups of sugar to make 1/2 batches

Step-by-step explanation:
Answer:
−3x+6
Step-by-step explanation:
please help me simplify this
Step-by-step explanation:
Given
sin(α+β) cos(α-β) +cos(α+β) sin(α -β)
We can see it is in the formula of
sin(A + B) = sinA cosB + cosA sinB
So now
Sin ( α + β + α - β)
= sin 2α
Or we can write sin2α as
= 2 sin α * cos α

Jaquin would like to install a rug in her square living room. Her living room has an area of 121 square feet. What should the side length of the rug measure?
Answer:
11 feet
Step-by-step explanation:
All the sides of a square are equal
the area of a square = length²
121 ft² = length²
to determine the length find the square root of the area, 121
√121 = 11 feet

Answer: x=50°
Step-by-step explanation:
For this question, you have to first find out whether you are using Sin, Cos or Tan.
To help you find out which one you are using you can use SOH CAH TOA to help you:
SOH-the 'S' is for Sin then the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH-the 'C' is for Cos and then the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA-the 'T' is for Tan then the 'O' and the 'A' is for Opposite over Adjacent.
In this, because you have the Hypotenuse (the length opposite the right angle) and the Adjacent (the length next to the angle you are finding) you would be using Cos.
So first you would write:
Cos x=59/91
But then because you want x on it's own you would do the inverse. So, instead of multiplying x by cos you would have to do cos-1 (the inverse of cos). This would be written as:
x=cos-1 59/91
To get the answer you would have to put this in your calculator.
So x=50°
Hope this helps :)
X/19 < -7
Inqualities
Because 19 is being divided, you have to do the opposite. What's the opposite of division? Multiplication. So multiply 19 to -7, then get rid of the 19 on the x's side(cuz it was cancelled out). Now you should have x<-133. In case you don't know, positive times negative equals negative, but negative times negative equals positive.

A triangle has sides of LaTeX: 1\frac{1}{6}1 1 6 inches, LaTeX: 1\frac{1}{3}1 1 3 inches, and LaTeX: 1\frac{2}{3}1 2 3 inches. What is the perimeter of the triangle? Make sure your answer is in simplest form.
Perimeter of Triangle = Side a + Side b + Side c
Perimeter of the Triangle =
( 1 1/6 + 1 1/3 + 1 2/3) inches
Lowest common denominator = 6
= 1 + 1 + 1 +(1/6 + 1/3 + 2/3)
= 3 + (1 + 2 + 4/6)
= 3 + 7/6
= 3 + 1 1/6
= 4 1/6 inches

2. Which is greater, 5.15 x 10-4 or 6.35 x 10-5
Answer:
6.35 x 10-5
Step-by-step explanation:
5.15 x 10-4 = 47.5
6.35 x 10.5 = 58.5
therefore 6.35 x 10-5 is greater
For the following right triangle, find the side length x.
х

15
Answer:
17
Step-by-step explanation:
h²=p²+b²
hypotenuse is x.
So, 8²+15²=289 which is 17²
so, h=17
Use the Pythagorean Theorem, a2+b2=c2 to find the length of a triangle when a = 9 feet and b = 40 feet.
c= 7 feet
c= 40 feet
c= 41 feet
c= 49 feet
Answer:
C
Step-by-step explanation:
Five more than twice a number is less than one more six times the number.
Choose one polynomial from each column below that will result in the given product. Select one option from each drop down. 24x^3y^2+16xy^3+12y^3 Column 1 a.) 4xy b.) 4x^2y c.) 4y^2 Column 2 d.) 6x+4y+3 e.) 6x^3+4xy+3y f.) 6x^2y+4x+3y^2
Answer:
[tex]Column\ 1: 4y^2[/tex]
[tex]Column\ 2: 6x^3+4xy+3y[/tex]
Step-by-step explanation:
Given
[tex]24x^3y^2+16xy^3+12y^3[/tex]
Required
Determine the product from the given column
[tex]24x^3y^2+16xy^3+12y^3[/tex]
Factor our [tex]y^2[/tex]
[tex]24x^3y^2+16xy^3+12y^3 = y^2(24x^3 + 16xy + 12y)[/tex]
Factor out 4
[tex]24x^3y^2+16xy^3+12y^3 = 4y^2(6x^3 + 4xy + 3y)[/tex]
So: the factors are:
[tex]4y^2[/tex] and [tex]6x^3 + 4xy + 3y[/tex]

If a car is moving at a speed of 30 miles per hour, how many miles
would a car travel in 180 minutes?
Answer:
90 miles
Step-by-step explanation:
There's more than one way in which to do this. I have chosen to convert '180 minutes' to '3 hours.'
Since distance = rate times time, we have here:
distance traveled in 180 minutes = (30 mph)(3 hr) = 90 miles

Find the coordinates of each point after the described reflection. Give the distance between each point and its reflection.
Complete Question:
Find the coordinates of the point after the described reflection. Give the distance between the point and its reflection. R(-5, 8) is reflected across the x-axis _____________.
Answer:
[tex](a)[/tex] [tex]R' = (-5,-8)[/tex]
[tex](b)[/tex] The distance is 16 units
Step-by-step explanation:
Given
[tex]R = (-5,8)[/tex]
Solving (a): Reflection across x-axis
The rule is:
[tex]R(x,y) ==> R(x,-y)[/tex]
So, the reflection of [tex]R = (-5,8)[/tex] is:
[tex]R' = (-5,-8)[/tex]
Solving (b): The distance between R and R'
Distance (d) is calculated as:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Where:
[tex]R = (-5,8)[/tex] ---- [tex](x_1,y_1)[/tex]
[tex]R' = (-5,-8)[/tex] --- [tex](x_2,y_2)[/tex]
This gives:
[tex]d = \sqrt{(-5- -5)^2 + (-8- 8)^2}[/tex]
[tex]d = \sqrt{(0)^2 + (-16)^2}[/tex]
[tex]d = \sqrt{256}[/tex]
[tex]d = 16[/tex]
The distance is 16 units
Yolanda ha comprado un coche por 8.200 euros. Lo ha pagado en tres partes. Primero pagó un 60% del valor del coche, después el 25% y por ultimo el resto ¿ cuánto pagó Yolanda la última vez?
Answer:
1.230 euros
Step-by-step explanation:
De la pregunta anterior se nos dice que:
Yolanda compró un coche por 8.200 euros. Lo ha pagado en tres partes.
Paso 1
Sea el porcentaje de la suma total de dinero = 100%
Primero pagó el 60% del valor del auto, luego el 25% y finalmente el resto.
Dejemos que el resto esté representado por x
Por eso;
Primera parte + Segunda parte + Tercera parte = 100%
60% + 25% + x = 100%
x = 100% - (60% + 25%)
x = 100% - 85%
x = 15%
Paso 2
¿Cuánto pagó Yolanda la última vez?
La última vez = Tercera parte y esto se calcula como:
15% de 8.200 euros
= 15/100 × 8.200 euros
= 1.230 euros
Yolanda pagó 1.230 euros la última vez.
