a sixth grade student can complete 20 multiplication facts in one minute if you works at the same rate how long should it take him to complete 35 multiplication facts? [type answer as decimal number.]
Answer:
It should take him 1.75 minutes to complete 20 multiplication facts, which is the same thing as 1 minute and 45 seconds, or 105 seconds.
Step-by-step explanation:
a. If it takes him one minute to complete 20 multiplication facts, that's 3 seconds per question, because 60/20 = 3.
b. Multiply 3 x 35 questions to get 105 seconds.
c. Divide 105 seconds by 60 seconds (60 in a minute) to get 1.75 minutes, which is the same thing as 105 seconds.
Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day and good luck on your assignment. :)

There are 40 animals in Mang Roman's farm.The ratio of cows to carabaos to goats to horses is 4:2:3:1. How many animals of each kind are there in Mang Roman's farm.
Answer:
there are
16, 8, 12 and 4 different animals
Step-by-step explanation:
Step-by-step explanation:
Step one:
given data
Number of Animals = 40
The given ratio is = 4:2:3:1
The total ratio is = 4+2+3+1= 810
Step two;
Applying the part to all method
The first animal
4/10=x/40
cross multiply
10x= 40*4
divide both sides by 10
x= 160/10
x= 16
for second we have
2/10=x/40
cross multiply
10x= 40*2
divide both sides by 10
x= 80/10
x= 8
for the third we have
3/10=x/40
cross multiply
10x= 40*3
divide both sides by 10
x= 120/10
x= 12
for the fourth we have
1/10=x/40
cross multiply
10x= 40*1
divide both sides by 10
x= 40/10
x= 4

can someone PLEASE help me find z and x !! (i will mark you brainliest)
Answer:
X=24 Z=110
Step-by-step explanation: correct me if im wrong because im not 100% sure.
Answer:
z=110° and x=24°
Step-by-step explanation:
z°=(5x-10)°[Being the pair of vertically opposite angle]
z+70°=180[Being the pair of straight angle]
or, z=180-70
z= 110
Again ,
z=(5x-10)°
or, 110=5x-10
or, 110+10=5x
or, 120=5x
or, 120/5=x
x=24°

please someone help me with this
First, find the slope using the equation, y2 - y1 / x2 - x1
1-5 / 4 - - 4 = -4/8 = -1/2
plug this into slope intercept form
y = -1/2x + b
Next use one of the points to find b using point-slope form. I will use (4,1)
y - y1 = m ( x - x1)
y - 1 = -1/2 (x - 4)
y -1 = -1/2x + 2
+1 +1
y = -1/2x + 3 is your equation
what is 4.8 × d = 1.2
Answer:
0.25

5 = .25
4.8 x .25 = 1.2
Sara earned money selling pies and cakes. For the cakes, she made a profit of $200 with an expense of $4 per cake. For the pies, she made a profit of $250 with an expense of $5 per pie. She sold the same number of cakes and pies. How many pies did Sara sell if she earned the same total profit for pies and cakes? Write an equation and then solve for x.
50 points! True or false? Will mark brainliest! No random answers please :)
Answer:
true because it have no common solution
Answer: false!
Step-by-step explanation:
To be parallel, the lines have to have the same slope. The slope for line a is 5, the slope for line b is -1/5. These lines are perpendicular.

For the model to scale, the ratio of the height to the side length should be the same for both the actual pyramid and the model. Is the model of Khufu's pyramid to scale? If not, is it close?
PLEASE HELP. I WILL MARK YOU BRANLIEST
Answer:
Scale Model of the Great Pyramid
You can build a model of the Great Pyramid, but first you need to scale it down. To do this, you will need to
make the pyramid 3,000 times smaller than it really is! To achieve that, every 30 meters of the pyramid is
represented as 1 centimeter.
Step-by-step explanation:
Are these triangles similar?
Answer:
B. Yes, by the AA Similarity Postulate
Step-by-step explanation:
This triangles are both similar based on the AA Similarity Postulate. We know that all angles are equal because...
m∠ABE = m∠CBD = 42° (because they are veridical/opposite angels)
m∠AEB = 180° - m∠ABE - m∠EAB = 180° - 42° - 53° = 85°
Then from here we know that
m∠BDC = 180° - 85° - m∠CBD
m∠BDC = 95° - 42°
m∠BDC = 53°
From here we see that they are similar because of the AA Similarity Postulate, since
m∠ABE = m∠CBD = 42°
m∠BDC = m∠EAB = 53°
m∠AEB = m∠BCD = 85°

Sara went shopping. She bought six oranges at $0.25 each, two apples at $0.40 each, three plums at $0.18 each. She gave the cashier $5.00. How much change will Sara receive from the $5.00?
Answer:
$2.16
Step-by-step explanation:
Amount of change received
= $[5.00-0.25(6)-0.40(2)-0.18(3)]
= $(5.00-1.50-0.80-0.54)
= $2.16
Describe the transformation that occurred

State the domain: x^2 +16x+64
Answer:
All real numbers
Step-by-step explanation:
x² + 16x + 64 is a parabola that opens up, when graphed.
This means it will have a U shape that will infinitely extend outwards in both directions, across the x axis.
So, the domain will include all real numbers.

A king owned land outside of his castle he has partitioned the land to give as gifts to his 5 sons what fraction of land did the king give to each of his sons here is zeke solution andy got 1/2 bill got 1/5 carl got 1/5 dirk got 1/8 and evan got 1/8 identify zeke's two errors correct them and explain why your answers are correct
Picture relating to the question is attached
Answer:
Andy = 1/2
Bill = 1/8
Carl = 1/8
Evan = 1/8
Dirk = 1/8
Step-by-step explanation:
According to the picture depicting the sharing of the land :
Fraction of the total rectangular plot = 1
Andy got a portion of the whole divided into 2 = 1/2
Fraction left after Andy's portion:
1 - 1/2 = 1/2
1/2 of the fraction left was divided equally between Dirk and Evan
Hence ;
1/2 of 1/2 = 1/2 * 1/2 = 1/4
Dirk's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Evan's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Fraction of land left :
1 - (1/2 + 1/8 + 1/8) = 1 - 3/4 = 1/4
1/4 was divided equally into 2 for Bill and Carl:
Bill's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Carl's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
