Answer:
x > -1
Step-by-step explanation:
-3x + 15 < 18
Subtract 15 from each side
-3x + 15-15 < 18-15
-3x < 3
Divide each side by -3, remembering to flip the inequality
-3x/-3 > 3/-3
x > -1
An engineer is building a bridge that should be able to hold a maximum weight of 1 ton. He builds a model of the bridge that is exactly 4 times smaller than the actual bridge.
16 ounces = 1 pound. 2,000 pounds = 1 ton.
If a test of the model shows that it holds 8,000 ounces, will the bridge hold 1 ton?
8,000 ounces on the model is equal to
ounces on the actual bridge.
Convert ounces to pounds. The actual bridge can hold
pounds.
Therefore, the bridge
hold 1 ton.
Answer:
the bridge holds one ton. on Edgunuity
Step-by-step explanation: <3
Answer: first one is 32000 the second one is 2000 and the third one Is it will hold 1 ton

Answer:
(2, 12)
Step-by-step explanation:
x + 10 = 4x + 4
- 4 - 4
x + 6 = 4x
- x - x
6 = 3x
divide 3 on each side
2 = x
then plug 2 in either equation
ei) y = 2 + 10
y = 12
how to multiply decimals when not using models
Answer:
You multiply it like normal numbers. But when you do, count how many numbers are behind the decimal, say there are 2 numbers behind the decimal, once you finished multiplying the numbers you would add up all the products you got and then put the first 4 numbers you wrote behind the decimal to get the final product.
Step-by-step explanation:
Say you were multiplying 14.63 and 7.74
14.63
x 7.74 Always starting from the right side of the equation
.5852 go to the left four digits and put a decimal then
↑←←←← just carry the decimal down and you'll end up with
10.2410 the final product
+ 102.4100
113.2362
(2x - 9) (x + 4) = 0
What the answer
Answer:
x = 4.5 AND x = -4
Step-by-step explanation:
for the first answer
add 9 to 0 and divide by 2
for the second answer
subtract 4
Answer:
x = 9/2 and x = -4
Step-by-step explanation:
you can set each expression in the parenthesis' equal to zero. this is due to it being multiplication so if one parenthesis equals 0, the answer will be 0
2x - 9 = 0 and x + 4 = 0
starting with 2x-9=0
add 9 to both sides
2x = 9
divide by 2
x = 9/2
then do x + 4 = 0
subtract 4
x = -4
so your two answers are
x = 9/2 and x = -4

Please help WHAT IS THE PERCENT OF 39.8 out of 200 QUICK PLEASE
Answer:
19.9%
Step-by-step explanation:
39.8/200 = 0.199 (move decimal two times)
19.9%
or you can just see what number get 200 to 100, which is by dividing by 2. What you do to the bottom you do to the top so 39.8/200 (divide both sides by 2) = 19.9/100
which is 19.9%.

Which of the following statements is true of the diagram?
Answer:
option 2
Step-by-step explanation:
QR = 15 ( triangle is a 8- 15- 17 Pythagorean triple )
cosP = [tex]\frac{PR}{PQ}[/tex] = [tex]\frac{8}{17}[/tex] ≠ [tex]\frac{8}{15}[/tex]
tanQ = [tex]\frac{PR}{QR}[/tex] = [tex]\frac{8}{15}[/tex] ≠ [tex]\frac{15}{8}[/tex]
sinP = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{15}{17}[/tex] ≠ [tex]\frac{8}{17}[/tex]
cosQ = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{15}{17}[/tex] ← correct statement
Answer:
its the cos q = 15/17
Step-by-step explanation:
cos q = 15 (adjacent) / 17 (hypothenuse)
Find the volume of a pyramid with a square base, where the side length of the base is
4.9 m and the height of the pyramid is 5.3 m. Round your answer to the nearest
tenth of a cubic meter.
Answer:
127.253 m^3
Step-by-step explanation:
To find the volume, we start by getting the area of the square base
Mathematically, that will be 4.9^2 m^2
To complete the volume, we multiply the area of the base by the height
= 4.9^2 * 5.3 = 127.253 m^3

The mean length of 10 childrens' big finger is 8.1cm.
The mean length of 11 adults' big finger is 14.1cm.
What is the mean length (rounded to 2 DP) of these 21 people's big finger?
Answer:
The mean length of 10 children's big finger is 8.1 cmAverage length of all the 10 children's finger is (8.1×10) cm = 81 cm.
The mean length of 11 adult's big finger is 14.1 cmAverage length of all the 11 adult's big finger is (14.1×11) cm =155.1
Mean length of these 21 people's big finger is[tex] \frac{(81 + 155.1)}{21} = 11.242857[/tex]Hence, 11.24 is the right answer.Shasta is going to her best friend's house for dinner. Her mother says she needs to be back in 2 and a half hours. If she leaves at 5:00 pm, what time will she be back?
Answer:
she will be back at 7:30pm
Step-by-step explanation:
From the question we are given
Time that Shasta leaves for her best friend place = 5:00pm
If she is to come back after 2 and a half hour, hence we will have to add 2hr 3ominutes to the time she left to know the time she will be back as shown:
She will be back at 5:00 + 2hr 30min = 7:30pm
Hence she will be back at 7:30pm
