Answer:
[tex]Estimate = 5.0kg[/tex]
Step-by-step explanation:
Given
[tex]Weight = 1.656kg[/tex]
Required
Determine the estimated for 3 containers
Since the weight of all containers are the same, we simply multiply the given weight by the number of containers.
i.e.
[tex]Estimate = Number\ of\ containers * Weight\ of\ each[/tex]
[tex]Estimate = 3 * 1.656kg[/tex]
[tex]Estimate = 4.968kg[/tex]
[tex]Estimate = 5.0kg[/tex] --- approximated
So, the estimated weight is 5.0kg

Which is one reason why this expression is equal to 0?
[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62} [/tex]
Answer:
0
Step-by-step explanation:
The given expression is :
[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62}[/tex]
We can solve the expression as follows :
[tex]\frac{ - 5.62 + 5.62}{5.62}=\dfrac{0}{5.62}[/tex] (As -5.62+5.62 equals to 0)
Any number multipled to 0 gives 0.
Hence, the value of the given expression is equal to 0.

Answer:
Answer B
Step-by-step explanation:
Write out f(x) and g(x) in a column; we will subtract g(x) from f(x):
f(x) = x^2 - 9 or f(x) = x^2 - 9
-g(x) = -(2 - x) or -g(x) = +x -2
---------------------------------
f(x) - g(x) = x^2 + x - 11 (Answer B)

Three uniform shirts sell for $34.50. How much will 5 uniform shirts cost?
Answer:
57.5
Step-by-step explanation:
Recognize our numbers
3,5,34.50
Three uniform shirts sell for 34.50
34.50/3
=11.5
How much will five cost?
5x11.5
=57.5
Hope this helps!
Answer:
55.25
Step-by-step explanation:
1. First we need to work out the price of ONE shirt. To do that we divide the total price of 3 shirts by 3.
34.50 / 3 = 11.05
2. Now we know that the price of one shirt is $11.05p we can multiply that by 5 to get the price of 5 shirts.
11.05 * 5 = 55.25
= $55.25p

In ΔDEF, the measure of ∠F=90°, the measure of ∠E=41°, and FD = 79 feet. Find the length of DE to the nearest tenth of a foot.
Answer:
120.4ft
Step-by-step explanation:
Find the diagram in the attachment.
The triangle shown is a right angled triangle with the side DE as the hypotenuse, EF is adjacent side while DF is the opposite side.
To get DE, we will use the SOH CAH TOA trigonometry identity
Using CAH which is defined as:
Cos(theta) = Adjacent/Hypotenuse
Cos 79°= 23/Hypotenuse
Hypotenuse = 23/cos79°
Hypotenuse = 23/0.191
Hypotenuse = 120.4feet
DE = 120.4feet (to nearest tenth)

Answer:
3√41
Step-by-step explanation:
The diagonal can be gotten using the pythagoras theorem
d² = l²+w²
d² = 12²+15²
d² = 144 + 225
d² = 369
d = √9*41
d = 3√41
Hence the diagonal is 3√41

What is X equal to if 1X+30=6X+20?
Answer:
x=2
Step-by-step explanation:
1*x+30=6x+20
Multiply 1*x=x
x+30=6x+20
Subtract 30 from both sides:
x+30-30=6x+20-30
Simplify:
x=6x-10
Subtract 6x from both sides
x-6x=6x-10-6x
Simplify:
-5x=-10
Divide both sides by -5
-5x/5=-10/-5
Answer:x=2

A ladder is leaning against a building so that the distance from the ground to the top of the ladder is one foot less than the length of the ladder. Find the length of the ladder if the distance from the bottom of the ladder to the building is 5 feet.
A right triangle with the hypotenuse measuring x and one leg measuring x minus 1.
(1 point)
11 feet
14 feet
12 feet
13 feet
Answer:
Length of ladder (hypotenuse) = 13 ft
Step-by-step explanation:
Given:
Length of base (base) = 5 ft
Length of ladder (hypotenuse) = a
Distance between ground and ladder top (perpendicular) = a - 1
Find:
Length of ladder
Computation:
a² = 5² + (a-1)²
a² = 25 + a² - 2a + 1
2a = 26
Length of ladder (hypotenuse) = 13 ft
1/3 plus 1/4 so what is the answer to this question
Answer: 7/12
Step-by-step explanation:
1/3 + 1/4
1/3 = 4/4 * 1/3 = 4/12
1/4 = 3/3 * 1/4 = 3/12
4/12 + 3/12 = 7/12
11 There are 136 people on a train.
34 of the people are children.
What percentage of the people on the train are adults?
Answer:
75%
Step-by-step explanation:
There are 136 people on a train
34 are children
Therefore the percentage of people that are adults can be calculated as follows
= 136-34
= 102
= 102/136 × 100
= 0.75 × 100
= 75%
Hence 75% are adults

Artificial grass sells for $10.98 per square yard final cost to buy and install 69.2 square yards if the seller charges $5.15 per square yard for labor round to the nearest cent
Answer:
$1,116.19.
Step-by-step explanation:
Given that artificial grass sells for $ 10.98 per square yard, to determine the final cost to buy and install 69.2 square yards if the seller charges $ 5.15 per square yard for labor, round to the nearest cent, the following calculation must be performed:
69.2 x (10.98 + 5.15) = X
69.2 x 16.13 = X
1,116,196 = X
Thus, the cost to purchase and install 69.2 square yards of artificial grass is $ 1,116.19.
Miguel can drive 4 times as fast as Raul can ride his bicycle. If it takes Raul 3 hours longer than Miguel to travel 68 miles, how fast (in mph) can Raul ride his bicycle? Round your answer to two decimal places, if needed.
Answer:
17 mphStep-by-step explanation:
Miguel's speed = m, Raul's speed = rGivenm = 4rDistance = 68 milesTime difference = 3 hoursSolutiontime = distance/speedSubstitute values and solve for r the equation of the time difference:
68/m + 3 = 68/r68/4r + 3 = 68/r17/r + 3 = 68/r17 + 3r = 683r = 68 - 173r = 51r = 17Raul's speed is 17 mph

the half life of carbon 14 is 5730 years. how much of a 50 gram sample would be left after 15000 years
Answer:
In this question (t½) of C-14 is 5730 years, which means that after 5730 years half of the sample would have decayed and half would be left as it is. After 5730 years ( first half life) 70 /2 = 35 mg decays and 35 g remains left. After another 5730 years ( two half lives or 11460 years) 35 /2 = 17.5mg decays and 17.5 g remains left . After another 5730 years ( three half lives or 17190 years) 17.5 /2 = 8.75mg decays and 8.75g remains left. after three half lives or 17190 years, 8.75 g of C-14 will be left.
