A soup recipe uses noodles, cheese, and potatoes in the extended ratio 4:5:7. How many cups of cheese are needed to make 192 cups of soup?
Answer: 60 cups of cheese
Step-by-step explanation:
noodles:cheese:potatoes
4:5:7
192 total cups of soup
each unit of recipe is 4+5+7=16
so divide total cups of soup by one recipe unit
192/16=12
This means 12 recipe units were used. So each value from ratio 12 times...
4:5:7 = one unit of soup (16 cups)
48:60:84 = 12 units of soup (192 cups)
So 60 cups of cheese are needed for 192 cups of soup.

r? What is r? 3/8 r = 6 HELP ME
Answer:
r = 16
Step-by-step explanation:
[tex]\frac{3}{8}r = 6 \\\\[/tex]
Multiply both sides by 8
[tex]8*\frac{3}{8}r = 6*8\\\\3r = 48\\[/tex]
Divide both side by 3
[tex]\frac{3}{3}r=\frac{48}{3}\\\\r = 16[/tex]
OR
Multiply both side by (8/3)
[tex]\frac{8}{3}*\frac{3}{8}r=6*\frac{8}{3}\\\\r = 2*8\\\\r = 16[/tex]
write an equation to represent the information in this problem. Jerel runs five days each week. on each of 4 days, he runs 2.3 km. if jerel runs a total of 14km, how many kilometers does he run on the fifth day?
Let x be the distance run on the fifth day
Total distance run on all the four days = 2.3 * 4 = 9.2 km
Required equation : x + 9.2 = 14
x = 14 - 9.2
x = 4.8 km

Answer:
1.47 years
Step-by-step explanation:
Given that,
The height of male elephant is given by the formula,
[tex]h=62.5\sqrt[3]{t} +75.8[/tex]
If h = 275 cm, we need to find the age of the elephant.
Put h = 275 cm in the above formula,
[tex]275=62.5\sqrt[3]{t} +75.8\\\\275-75.8=62.5\sqrt[3]{t}\\\\199.2=62.5\sqrt[3]{t}\\\\t=1.47\ years[/tex]
So, the required time be 1.47 years.

Answer:
C
why does it say a minimum of 20 words
I need someone to answer this
Answer:
(a+b)*(a+b)
c*c
(1/2*a*b)*4
Step-by-step explanation:
The area of a square is equal to side times side, so a+b=one of the sides of a square so you multiply this by another a+b to get the whole square
Same as the last part but c is equal to one side so we do c*c for the are
The area of a triangle is 1/2*base*height, so we do 1/2*a*b since a is equal to the base of the triangle and b is equal to the height. This is only equal to 1 triangle so we multiply this by 4 since there are 4 triangles in total
brass is an alloy of zinc and copper. if 30% of the content is zinc . find the weight of zinc and copper in 300 gram of brass.
Step-by-step explanation:
Here's your solution
=> percentage of zinc = 30%
=> total weight of alloy = 300 gram
=> amount of zinc = (30/100)*300 = 90 gram
=> amount of copper = 300 - 90 = 210 gram

Find the values of a and b given that the polynomial P(x) = x^3+ ax^2 +x+b, is divisible by
both x-1 and x + 3.
Answer:
a=4
b=-6
Step-by-step explanation:
If P(x) is divisible by x-c, then P(c)=0.
So P(1)=0 implies 1^3+a1^2+1+b=0
and
P(-3)=0 implies (-3)^2+a(-3)^2+-3+b=0
So notice we have a system to solve.
Let's simply it.
First equation:
1^3+a1^2+1+b=0
1+a+1+b=0
2+a+b=0
a+b=-2
Second equation:
(-3)^3+a(-3)^2+-3+b=0
-27+9a-3+b=0
9a+b-30=0
9a+b=30
Let's put our system together:
a+b=-2
9a+b=30
This is setup so if we subtract the equations b will eliminate allowing us to solve for a:
-8a=-32
a=4
If a=4 and a+b=-2, then 4+b=-2 giving us b=-6.
a=4
b=-6
Can anyone solve this question??? plss plsss its my request to all if any one can solve this question I will mark him/ her the brainliest
Answer:
a) ∠EAB = 180° - 90° - 30° = 60°
∠EBA = 180° - 90° - 60° = 30°
a) ∠EBA = 30°
b) ∠DCA = 180° - 90° - 30° = 60°
∠EBA ≅ ∠DAC, ∠EAB ≅ ∠DCA, ∠AEB ≅ ∠CDA
ΔEBA ≅ ΔDAC because of the AAA postulate
c) EB ≅ DA, EA ≅ DC, AB ≅ CA
d) AB = CA given
sin ∠EAB = EB/AB (sin 60°) EB = (0.8660)AB
cos ∠EAB = EA/AB (cos 60°) EA = (0.5)AB
cos ∠DAC = AD/CA (cos 30°) AD = (0.8660)CA
sin ∠DAC = CD/CA (sin 30°) CD = (0.5)CA
ED = EA + AD
ED = (0.5)AB + (0.8660)CA
since AB = CA, ED = 1.366CA
since EB = (0.8660)AB and AB = CA, then EB = 0.866CA
since CD = 0.5CA,
EB + CD = 0.866CA + 0.5CA = 1.366CA
EB + CD = 1.366CA
1.366CA = 1.366CA
Proof: ED = EB + CD

Which is a perfect square?
6^1
6^2
6^3
6^5
Answer:
6^2
Step-by-step explanation:
6^2 because,
6^1 is not a perfect square because 6 is its own number because 6 x 1 =6 Therefore being eliminated.
6^3 is not a perfect square because 6 x 6 x 6 (216) is cubed not square
*This one almost tricked me*
6^5 is not a perfect square because 6 x 6 x 6 x 6 x 6 (7776) it isn't an equal factor combination, that when multiplied together, produce the number 7,776. That means 7,776 is not a perfect square.
6^2 is a perfect square because 6x6= 36 and 36 is a perfect square.
Therefore, its 6^2

Ms Matthews has 200 sheets of construction paper she will give each of her 27 students an equal number of whole sheets to use for a project how many sheets will each students an equal number of whole sheets will each students get ? how sheets many will be left over?
Answer:
Each student will get 7 sheets with 11 sheets left over.
Step-by-step explanation:
divide 200 and 27 to get 7
7 sheets for each student
then multiply 27 and 7 to see how many sheets of paper she gave to her students.
that will give you 189
then 200-189=11 sheets left over

Answer:
[tex]\tan(A - \frac{\pi}{4}) = \frac{-\sqrt{15}- 1}{1 -\sqrt{15}}[/tex]
Step-by-step explanation:
Given
[tex]\tan A =-\sqrt{15[/tex]
Required
Find [tex]\tan(A - \frac{\pi}{4})[/tex]
In trigonometry:
[tex]\tan(A - B) = \frac{\tan A - \tan B}{1 + \tan A \tan B}[/tex]
This gives:
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - \tan \frac{\pi}{4}}{1 + \tan A \tan \frac{\pi}{4}}[/tex]
[tex]tan \frac{\pi}{4} = 1[/tex]
So:
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - 1}{1 + \tan A * 1}[/tex]
[tex]\tan(A - \frac{\pi}{4}) = \frac{\tan A - 1}{1 + \tan A}[/tex]
This gives:
[tex]\tan(A - \frac{\pi}{4}) = \frac{-\sqrt{15}- 1}{1 -\sqrt{15}}[/tex]
