What is the area of the triangle?

Answer:

g(5) = 15 and f(5) = 7

Step-by-step explanation:

f(5) = x + 2

f(5) = 5 + 2

f(5) = 7

g(5) = 3x

g(5) = 3(5)

g(5) = 15

plz mark as brainliest if correct!!!

Answer:

21

Step-by-step explanation:

because firstly u substitute 5 into x in the f equation

so it will be f(x)=5+2=7

the substitute 7 into the g equation

so g(x)= 3 x 7= 21

Answer:

just tell her that you want to see your friends again or say that you think it will have a better effect on your grades. you could say that it would be eaiser to pay attention in class and that CV cases are droping so it would be still be safe to go.

Step-by-step explanation:

Hope this helps!

Answer:

I have already switched from online to in-person, and I would say it was a pretty great decision. Some points you could bring up are ;

o It'll help your grades. (Personally, I was really struggling with my grades while doing online but, as soon as I switched my grades raised quick!)

o You miss your friends, or just seeing humans lol. (It's been almost an entire year we've been on lockdown! No one can see friends, or people in general. If you look it up, its this has taken a big toll on people's mental health.)

o Just to be able to get out of the house for a few hours. (We've been stuck inside with nothing to do besides, sit and do school and spend all of our time looking at our screens. Just tell her it's to much and you need a break.)

Hope this helps !!

Answer:

72

Step-by-step explanation:

Answer:

speed in still water = 9 mph

total time = 12 hours

Step-by-step explanation:

speed = distance/time

distance = speed * time

Traveling downstream:

speed of river = 3 mph

speed of canoe in still water = v

speed of canoe going downstream = v + 3

distance = 96/2 = 48

time = t

distance = speed * time

48 = (v + 3)(t)

Traveling upstream:

speed of river = 3 mph

speed of canoe in still water = v

speed of canoe going downstream = v - 3

distance = 96/2 = 48

time = 2t

distance = speed * time

48 - d = (v - 3)(2t)

48 = (v + 3)(t)

48 = (v - 3)(2t)

vt + 3t = 48

2vt - 6t = 48

     -2vt - 6t = -96

(+)   2vt - 6t = 48

------------------------

           -12t = -48

t = 4

vt + 3t = 48

4v + 3(4) = 48

4v + 12 = 48

4v = 36

v = 9

speed in still water = v = 9 mph

total time = t + 2t = 3t = 3(4) = 12 hours

Answer:

She has 13 and [tex]\frac{3}{4}[/tex] or 13.75 mins left for question c.

Step-by-step explanation:

first convert both fractions into an improper fraction to make it easier:

[tex]9\frac{3}{4} = \frac{39}{4}[/tex]

[tex]6\frac{1}{2} = \frac{13}{2}[/tex]

add both fractions, make sure both denominators are the same:

[tex]\frac{13}{2}[/tex] x 2 = [tex]\frac{26}{4}[/tex]

[tex]\frac{39}{4} + \frac{26}{4} = \frac{65}{4}[/tex]

convert back to a mixed fraction:

[tex]\frac{65}{4} =[/tex] [tex]16\frac{1}{4}[/tex]

subtract the answer from 30:

[tex]30 - 16\frac{1}{4} = 13\frac{3}{4}[/tex]

Celia has 55/4 minutes to do question C.

A fraction is deemed improper if the numerator is more than or equal to the denominator.

Given, Celia had 30 minutes to do a three-problem quiz.

She spent 9 3/4 minutes on question A and 6 1/2 minutes on question B.

In order to solve the problem:

First, we convert mixed fraction to improper fraction.

That means, [tex]9\frac{3}{4}[/tex] = 39 /4 and [tex]6\frac{1}{2}[/tex] = 13/2

Now, the total time to do the quiz is 30 minutes.

That means,

time for question A + time for question B + time for question C = 30 minutes.

39/4 + 13/2 + time for question C  = 30

time for question C = 30 - 39/4 - 13/2

time for question C = 55/4 minutes.

Therefore, She has left 55/4 minutes.

Answer:

116 degrees

Step-by-step explanation:

180 - (26 + 90)

180 - 116 = 64 degrees

180 - 64 degrees = 116 degrees

Angle 1 = 116 degrees

Hope that helps!

Answer:

<1 = 116

Step-by-step explanation:

90 + 26 + x = 180

116 + x = 180

x = 64

<1 + 64 = 180

<1 = 116

Answer:

Height = 13.5 cm

Perimeter = 81 cm

Step-by-step explanation:

The Area of a parallelogram is given as the product of the base and its height.

A = base * height

Area, A = 364.5 cm²

Base, b = 27cm

Height, h =?

Hence,

364.5 cm² = 27cm * h

h = 364.5 cm² / 27cm

h = 13.5 cm

Perimeter of parallelogram :

P = 2(a + b)

a = height of sides ; b = base

P = 2(13.5cm + 27cm)

P = 2(40.5)

P = 81 cm

Answer:

63.6mm

Step-by-step explanation:

According to cosine rule;

AB² = BC²+AC²-2(BC)(AC)cos m<C

Substitute the given values

AB² = 70²+40²-2(70)(40)cos 64

AB² = 4900+1600-5600cos64

AB² = 6500-5600(0.4384)

AB² = 6500-2,454.87

AB² = 4,045.12

AB = √4,045.12

AB = 63.6mm

Hence the length of AB is 63.6mm

Answer:

at least 71 miles each day

Step-by-step explanation:

212 divided by is 70.6

so u can round up to 71.

The required number of miles she will run is 2 miles each day or 1 mile each day.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Faith wants to run at least 7 miles this week. She has already run 212 miles. She plans to run an equal distance on each of the last 3 days of this week.
So,
There are two ways,
1st. she must run for 1 mile each day of the week,

2nd she must run for 2 miles on the last three days of the week and 1 mile on any day of the 4 days of the week.

Thus, The required number of miles she will run is 2 miles each day.
