Answer:
4+2=6
15*6=90
9+9=18
18*3=54
90+54=144
Step-by-step explanation:
you have to add both the W and H together and then multiply them by the number of windows (4+2=6 , 16*6=90)
and the same with the garage doors (9+9=18, 18*3=54) then you take you two totals from multiplying and add them together (90+54=144)
Answer:
11
Step-by-step explanation:
f(x)=3x+8
f(1)=3(1)+8
f(1)=3+8
f(1)=11
Like what u need help with
Given that Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second.
An olympian ran the 100-meter dash in 9.6 seconds.
Then speed of olympian = distance/ time = 100 meter/ 9.6 seconds = 100 meter/ 9.6 seconds = 10.4166666667 meter/ seconds
whis is approx 10.42 meter/seconds
Now we need to find about how much faster was Sarah the cheetah’s speed, to the nearest tenth of a meter per second.
16.8-10.42 = 6.38 = 6.4
Hence speed of Sarah the cheetah's is approx 6.4 meter per second more than the speed of olympian.
