Answer:
Amir 20 Rita 45
Step-by-step explanation:
20/4=5
5*9=45
so this satisfices the ration 4:9
Answer:
Amir : 20 sweets and Rita : 45 sweets
Step-by-step explanation:
Rita has 25 more in all answers. to get the answer, this is to see which one : 4:9 ; 20:45.
we multiply 4 and 45 and 9 and 20. if we multiply them, both answers are 180. this means it is equal and that is the answer.

Luke has a board 5
6
of a yard long. He needs to cut the board into 5 equal sections.
Use the expression
to find the length of each section.
Each section is
yard long.
Answer:
1/6 of a yard
Step-by-step explanation:
Length of the board = 5/6 yard
He needs to cut the board into 5 equal sections.
Length of each section = length of the board ÷ number of sections
= 5/6 ÷ 5
= 5/6 × 1/5
= (5*1)/(6*5)
= 5/30
= 1/6
Length of each section = 1/6 of a yard
A 26-ft ladder leans against a building so that the angle between the ground and the ladder is 81 degrees. How high does the ladder reach on the building? the answer is in ft
Answer:
25.7 feets
Step-by-step explanation:
From the diagram attached, we could use trigonometry to obtain the height,h :
Using the trigonometric relation :
Sin θ = opposite / hypotenus
Opposite = h
Hypotenus = 26 feets
Sin 81° = h / 26
Height, h = 26 * sin 81°
h = 26 * 0.9876883
h = 25.679
Height, h = 25.7 feets

Please show your work need help!
Answer:
See below for answers and explanations (along with a graph)
Step-by-step explanation:
Refer to the equations for a limaçon:
y=a+bcos∅ (horizontal line of symmetry) and y=a+bsin∅ (vertical line of symmetry) where a/b determines the type of limaçon.
This is an inner loop limaçon because 36/70<1, so its horizontal axis intercepts are 36 and -36 (marked in red) and its vertical axis intercepts are 0, 36+70=106 and 70-36=34 (marked in green)

QuestionDuring their team meeting, both managers shared their findings. Complete the statement describing their combined results. Select the correct answer from each drop-down menu.The initial number of video views was the initial number of site visits, and the number of video views grew by the number of site visits.The difference between the total number of site visits and the video views after 5 weeks is .
Answer:
The initial number of video views was more than the initial number of site visits, and the number of video views grew by a smaller factor than the number of site visits. The difference between the total number of site visits and the video views after 5 weeks is 20,825
Step-by-step explanation:
the initial video view was 5120 and the initial number of site visits were 4800, so the initial video view was more than.
The video views grew by 5/4 and the number of site visits grew by 3/2, and since 3/2 is > 5/4, the video views grew by a smaller factor than the number of site visits.
the result for the video views after 5 weeks is 15,625 and the site visits after 5 weeks is 36450, so 36450-15,625=20,825

Which equation represents a line that has a slope of – 2/3 and a y-intercept of 4?
A)
2x + 3y = 12
B)
2x - 3y = 12
C)
3x - 2y = 12
D)
3x + 2y = 12
Answer:
A
Step-by-step explanation:
Slope-intercept form: y=mx+b
2x+3y = 12
3y = 12-2x
y = (12-2x)/3
y = 4-2/3x
Here we can see that the slope is -2/3 and y-intercept 4. We already got the answer so we dont need to try the other options.
What is the circumference of a circle with a radius of 6 inches?
Answer:
37.7in
Step-by-step explanation:
C=2πr=2·π·6≈37.69911in
Answer:
37.6 (simplified)
Step-by-step explanation:
The formula for circumference is 2[tex]\pi[/tex]*r. Simply replace r with 6 and multiply from there. Normally you would simplify pi down to 3.14 as well.
A researcher is trying to identify whether household substances are basic. Which approach would BEST help the researcher investigate
whether substances are basic?
A. Observe each substance and record its color.
o B. Measure the temperature of each substance.
C. Test each substance with red litmus paper.
OD. Mix each substance with a weak base and record the results.
Answer:
C. Test each substance with red litmus paper.
Step-by-step explanation:
C is the correct answer because when you apply a base with a red litmus paper the outcome color should result in blue.
The best approach best investigate whether substances are basic is to test each substance with red litmus paper.
What is basic compound?In general, bases are substances that can neutralise a small amount of acid. Ammonia and sodium carbonate are both bases even though neither of them includes OH groups.
When in contact with basic chemicals, red litmus paper turns blue instead of red. Thus we should use red litmus paper to test the basicity of home items.
Acids are the only substances that bases react with, hence using weak bases will not produce the intended results since weak bases only partially dissociate.Color does not indicate basicity or acidity.The acidity of a substance can be determined by placing red litmus paper in contact with acid, which causes the paper to turn blue.Hence, the test each substance with red litmus paper.

Gabriel brings 25 cupcakes to share with his classmates at school. At the end of the day, he has 3 cupcakes remaining. What percent of the total cupcakes did Gabriel share with his classmates?
A 12%12%
B 22%22%
C 75%75%
D 88%
Answer:
Answer D 88%
Step-by-step explanation:
To figure this question out we first need to find 1% of 25, which is .25 and then we need to find what percentage 3 is of 25, and so 12 x .25 = 3 which means 3 is 12% of 25, now just subtract it from 100% and we get 88%

Answer:
1.False
2. True
3.) True
4. False
5.) False
6.) True
Step-by-step explanation:
1.)
Range = maximum - minimum
New year's eve :
Maximum = 22 ; minimum = 3
Range = 22 - 3 = 19
2.)
Median for Thanksgiving = 17
50% up to 17 ;hence the remaining 50% is also 17 and above

Each day Theo versus dog 15 minutes in the morning and 25 minutes in the afternoon evaluate the expression 7 x (15 + 25) to find how many minutes to theo dog each week
Answer: 280 minutes
Step-by-step explanation:
Given
Expression is [tex]7\times (15+25)[/tex]
Apply distributive law i.e.
[tex]a(b+c)=a\cdot b+a\cdot c[/tex]
[tex]\Rightarrow 7(15+25)=7\cdot 15+7\cdot 25\\\Rightarrow 7(15+25)=105+175=280[/tex]
Thus, theo dog took 280 minutes each week
there is given the numbers equals to 8 and DC equals to 3.2 and BE quals to 9 and find BC
Given:
Consider [tex]AB\parallel DE[/tex] in triangle ABC and [tex]AD=8,DC=3.2,BE=9[/tex].
To find:
The length of BC.
Solution:
Basic proportionality theorem (BPT): If a line intersect the two sides of triangle and parallel to the third side, then that line intersects the other two sides proportionally.
Using Basic proportionality theorem, we get
[tex]\dfrac{AD}{DC}=\dfrac{BE}{EC}[/tex]
[tex]\dfrac{8}{3.2}=\dfrac{9}{EC}[/tex]
On cross multiplication, we get
[tex]8\times EC=9\times 3.2[/tex]
[tex]EC=\dfrac{28.8}{8}[/tex]
[tex]EC=3.6[/tex]
Now,
[tex]BC=BE+EC[/tex]
[tex]BC=9+3.6[/tex]
[tex]BC=12.6[/tex]
Therefore, the length of side BC is 12.6 units.
