Geometry question, help ya girl out
Answer:
A=36 a means area
Step-by-step explanation:
A=a+b/2
h=6+12/2
times 4=36
Answer:
=36cm^2
Step-by-step explanation:
6-12=6 (total cm of the bases for triangle B and C)
6/2= 3 (base of B and C trialngleis 3 )
Triangle formula: bh 1/2
(base)b= 3cm
height(h)=4
Formula: (3)(4) 1/2
=12 1/2
=6cm^2
^ area of 1 triangle
There are 2, so
6*2=12cm^2 (area of triangles )
Area of rectangle: L*W
4*6=24cm^2
Total area of trapezoid
=24cm^2+12cm^2
=36cm^2
Which set represents the zeros of the function f(x) = 7x2 – 28x + 21?
Answer:
change f(x) to 0 than 7*2x=14x
0=14x-28x+21
0=-14x+21
-21=-14x
x=3/2

Evaluate 32 + (5 − 2) ⋅ 4 − 6 over 3. (1 point)
3 squared.
Explanation: Because it's correct.
Answer:
i did 3^2 and the answer would be 19 for that.
Step-by-step explanation:
3^2 + (5 − 2) ⋅ 4 − 6 over 3
9 + 3 ⋅ 4 - 6 over 3
9 + 12 - 6 over 3
21 - 6 over 3 (which equals 2)
is 19 :)

A florist sold 14 flower bouquets yesterday, including 7 lily bouquets. Based on past data, how many of the next 20 bouquets sold should you expect to be lily bouquets?
Answer:
10
Step-by-step explanation:
From past data:
Fraction of lily sold :
Total flowers / number of lily
Total flowers = 14
Number of lily = 7
Fraction of lily = 14 /7 = 1/2
Going by these ;
Expected number of lilies in the next 20 bouquets sold :
Fraction of lily * number of flower in bouquet
1/2 * 20
= 10 lilies
Two ships are near a buoy in the open ocean. One ship is 20 km due north of the buoy, and the other ship is 13.5 km due east of the buoy.
Round the answer to the nearest tenth.
Answer:
24 km is your answer
Step-by-step explanation:
Let x be the distance between the two ships.
Hypotenuse side = x km
Adjacent side = 13.5 km
Perpendicular side = 20 km
by using Pythagoras theorem:
x²= 13.5²+ 20²=582.25
x=√ 582.25
х =24.129857024 km
Therefore, the distance between two ships to the nearest tenth place is, 24.1 km
Which number line and expression show how to find the distance from 4 to 1?
Answer:
C
Step-by-step explanation:
Which rule describes the x-coordinates in the translation below?.
x + 0
x + 6
x – 6
x + 2
Answer:
A) x + 0
Step-by-step explanation:
In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)
In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)
Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.
Therefore, the rule for x-coordinates = x + 0
Answer: A) x + 0

The time t required to do a job varies inversely as the number of people working. It takes 4 hr for 7 cooks to prepare the food for a wedding rehearsal dinner. How long will it take 8 cooks to prepare the dinner?
9514 1404 393
Answer:
3 1/2 hours
Step-by-step explanation:
If there are 8/7 times as many cooks, it will take 7/8 the amount of time. (That's what "inversely proportional" means.)
(7/8)(4 h) = 28/8 h = 3 1/2 h
It will take 8 cooks 3 1/2 hours to prepare the dinner.
Pls tell me which square unit :(
Answer:
8
Step-by-step explanation:
If I am doing this correctly you count all the dots the triangles lines are on. Which is 8 to find the area. Hope it helped have a wonderful day!

An item costs $420 before tax, and the sales tax is $25.20 . Find the sales tax rate. Write your answer as a percentage.
Answer:
6%
Step-by-step explanation:
Given data
Cost of item= $420
Tax= $25.2
Required
The tax rate
=25.2/420*100
=0.06*100
=6%
Hence the tax rate is 6%
A cereal box has a surface area of 280 square inches. What is the surface are of a similar box that is larger by a scale factor of 1.4 ?
Answer: 548.8 square inches
Step-by-step explanation:
From the question, we are informed that a cereal box has a surface area of 280 square inches.
The surface area of a similar box that is larger by a scale factor of 1.4 will be gotten by multiplying 280 by the scale factor's square. This will be:
= 280 × (1.4)²
= 280 × 1.96
= 548.8 square inches

In Mr. Jegou's neighborhood 35% of the houses are blue. Write the
percent that do not live in blue houses as a decimal and a fraction in simplest form
Answer:
Fraction: 3/20
Decimal: 0.35
Step-by-step explanation:
a) 100% - 35% = 65
So, 65% of the houses are NOT blue.
..............................................
Fraction: 3/20
Decimal: 0.35
Answer:
65/100 or 0.65
Step-by-step explanation:
To answer this problem all you have to do is subtract 35%.If an A+ is an 100 percent,Then subtract 100 and 35 giving you 65 percent.
But if you do not know how to turn a fraction or decimal,then i will show you.every time you have a number in the tens place,add a zero and the add the decimal and finally add 65 which making look like this:0.65.
Fraction is easy to do as long as you do a number out of 100,like this:65/100.
simple :)

Corey needs at least 2 gallons of paint to make a mural. If Corey has 6 quarts and 3 pints of paint, will he be able to make a mural?
Answer:
no
Step-by-step explanation:
4 quarts = 1 gallon, so he would have 1.5 gallons.
8 pints = 1 gallon, he would need 4 pints to have 2 gallons
Answer:
No he will not.
Step-by-step explanation:
6 quarts to a gallon is 1.5
3 pints to a gallon is 0.375
you add those together you get 1.875 not 2
Just please help me, im trying to cram multiple things at once (house is crazy) and I just cant seem to concentrate and understand these.
Answer:
Step-by-step explanation:
here is how you find the answer
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
now apply the above rules to the given triangle
where we are given the angle of 30° and the Adj side of 27
y is the Hyp of this triangle and x is the Opp side of this triangle, now plug in the given values as follows
so use CAH Cos(30) = 27 / Hyp
Hyp = 27 / Cos(30)
Hyp = 27 / ([tex]\sqrt{3}[/tex] / 2)
Hyp = 27 * 2 / [tex]\sqrt{3}[/tex]
Hyp = 54 / [tex]\sqrt{3}[/tex]
y = 54 / [tex]\sqrt{3}[/tex]
use SOH, since we know the exact value for the Hyp from above
Sin(30) = Opp / ( 54 / [tex]\sqrt{3}[/tex] )
Sin(30) * 54 / [tex]\sqrt{3}[/tex] = Opp
1/2 * 54 / [tex]\sqrt{3}[/tex] = Opp
27 / [tex]\sqrt{3}[/tex] = Opp
x = 27 / [tex]\sqrt{3}[/tex]

In a fruit cocktail, for every 20 ml of orange juice you need 10 ml of apple juice and 15 ml of coconut milk. What proportion of the cocktail is apple juice?
Give your answer as a fraction in its simplest form.
Answer:
5/9
Step-by-step explanation:
First, find the total number of mL in the drink:
20 + 10 + 15
= 45
There are 10 mL of apple juice, so the proportion will be 10/45
Simplify this by dividing the numerator and denominator by 5:
10/45
= 5/9
So, 5/9 is the proportion of the cocktail that is apple juice
Remy stands on a dock at the edge of the lake represented by point C. Points A and B represent two buoys anchored in the lake. Remy plans to swim from C to A, then to B and then back to C. The shortest distance from Remy to the swim route AB is 60 meters and is measured from C to D.
What is the total distance, in Meters that Remy will swim? Round your number to the nearest whole number.
*see attachment for the diagram and more info
Answer:
236 m
Step-by-step explanation:
Total distance Remy will swim = CA + AD + DB + BC
✔️Find AD and CA using trigonometry function:
Reference angle = 43°
Opp = AD
Hypotenuse = CA
Adjacent = 60 m
Tan 43 = opp/adj
Tan 43 = AD/60
60 × Tan 43 = AD
60 × 0.93 = AD
55.8 = AD
✅AD = 55.8 m
Cos 43 = adj/hyp
Cos 43 = 60/CA
CA × Cos 43 = 60
CA = 60/Cos 43
CA = 60/0.73
✅CA ≈ 82.2 m
✔️Find DB and BC:
Refernece angle = 27°
Adj = 60 m
Opp = DB
hyp = BC
Tan 27 = opp/adj
Tan 27 = DB/60
60 × Tan 27 = DB
60 × 0.51 = DB
✅DB = 30.6 m
Cos 27 = adj/hyp
Cos 27 = 60/BC
BC = 60/Cos 27
BC = 60/0.89
✅BC ≈ 67.4 m
✔️Total distance Rent will swim = 55.8 + 82.2 + 30.6 + 67.4 = 236 m
solve vw^2+y=x for w
Answer: The given equation is
And we have to solve for w .
For that we first get rid of y. And for that, we subtract y from both sides,
Now we need to separate v from w square, and for that, we divide both sides by v, that is
Now to get rid of square, we take square root to both sides. That is
And that's the required answer.
Step-by-step explanation:
Answer:
vw^2+y=x
vw²=x-y
w²=(x-y)/v
w=√{(x-y)/v}

Given that charge for each tabletop is 8.50 per square foot, create an itemized
invoice to show the cost of
each tabletop from 10-12 and the total cost.
Table 1 - $
Table 2 - $
Table 3 - $
Total cost - $
Answer:
Table 1: for 10 square feet it would be: 85.00
Table 2: would be 93.50
Table 3: would be 102.00
The Total cost would be: 280.50
