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.

Find the missing length marked with a question mark.
UVW-USR
Given:
[tex]\Delta UVW\sim \Delta USR[/tex]
To find:
The missing length marked with a question mark.
Solution:
Let x be the missing value.
We have,
[tex]\Delta UVW\sim \Delta USR[/tex]
Corresponding sides of similar triangles are proportional, so
[tex]\dfrac{UV}{US}=\dfrac{VW}{SR}=\dfrac{UW}{UR}[/tex]
Using this, we get
[tex]\dfrac{UV}{US}=\dfrac{UW}{UR}[/tex]
On substituting the values, we get
[tex]\dfrac{70}{x}=\dfrac{55}{44}[/tex]
[tex]\dfrac{70}{x}=\dfrac{5}{4}[/tex]
On cross multiplication, we get
[tex]70\times 4=5\times x[/tex]
[tex]280=5x[/tex]
[tex]\dfrac{280}{5}=x[/tex]
[tex]56=x[/tex]
Therefore, the missing length is 56 units.

2(2x + 3)=4x + 3x - 9
Answer:
x=5
Step-by-step explanation:
Answer:
2(2x + 3)=4x + 3x - 9
4x+6=4x+3x+−9
4x+6=(4x+3x)+(−9)
4x+6=7x+−9
4x+6=7x−9
4x+6−7x=7x−9−7x
−3x+6=−9
−3x+6−6=−9−6
−3x=−15
-3x/-3=-15/-3

Solve the following inequality. 36> -2(x+4)+14
Answer:
x > - 15
Step-by-step explanation:
Given
36 > - 2(x + 4) + 14 ← distribute and simplify right side
36 > - 2x - 8 + 14
36 > - 2x + 6 ( add 2x to both sides )
2x + 36 > 6 ( subtract 36 from both sides )
2x > - 30 ( divide both sides by 2 )
x > - 15

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
Olivia and her three siblings bring a sack lunch to school each day, consisting of a bagel, an apple, a cookie, and a juice box. When Olivia's mom goes grocery shopping, she likes to purchase the same amount of each lunch item so that she can make complete lunches, with no leftover items. However, each item comes in a different sized package, as shown below: Bagels: six in a bag Apples: eight in a bag Cookies: twelve in a box Juice Boxes: nine in a box Find the least number of packages she must purchase in order to have the same amount of each item.
Olivia's mom should purchase how many bags of apples?
Answer:
72
Step-by-step explanation:
Find the LCM
6=2x3
8=2x2x2
9=3x3
12=2x2x3
LCM=2³x3²
=72
solve the equation
2(h-8) - h=h - 16
A h = 8
B h= -8
C h = infinitely many solutions
D h = no solution
Answer:
2(h-8)-h=h-16
2(h-8)=h+h-16
2(h-8)=2h-16
2(h-8)=2(h-8)
h-8=h-8
h-h=8-8
0=0 so their can be infinite value of h.
hence c is correct
we can put in place of anything but answer will be zero.
Answer:
C h= infinitely many solutions
Step-by-step explanation:
when you replace h with any number it is true
say h= 3
2(3-8) - h = h-16
2(-5) - 3 = 3 - 16
-10 - 3 = -13
-13 = -13
using distributive property:
2h-16-h = h-16
combine like terms
h-16=h-16
it is the same expression on both sides of the equal sign
hope that helps!
The number of apples purchased at 56 and be represents the number of bananas purchased at 10 since each of the total value of the purchase and sent a plus B 25 a plus B turn a +15 B 15 8+10 B
The question isn't well formatted and incomplete :
Complete question :
If A represents the number of apples purchased at 15 cents each, and B represents the number of bananas purchased at 10 cents each, which of the following represents the total value of the purchases in cents?
Answer:
15A + 10B
Step-by-step explanation:
Number of apples purchased = A
Price per apple = 15 cents
Number of bananas purchased = B
price per banana = 10 cents
Total price of A apples :
Price per apple * number of apples = 15A
Total price of B bananas :
Price per banana * number of bananas = 10B
Total value of purchase :
Total price of A apples + Total price of B bananas
15A + 10B

Under his cell phone plan, Hunter pays a flat cost of $61.50 per month and $5 per gigabyte. He wants to keep his bill under $70 per month. Write and solve an inequality which can be used to determine xx, the number of gigabytes Hunter can use while staying within his budget.
Answer:
$70 >= $61.50 + $5x
Step-by-step explanation:
With the values provided the only variable would be the number of gigabytes. Since Hunter does not want to spend more than $70 then the value of the amount of money he is paying for gigabytes plus the flat cost needs to be less than or equal to $70. Therefore, the following inequality would represent this scenario best...
$70 >= $61.50 + $5x
