A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
63 in 2
90 in 2
120 in 2
126 in 2
Answer:
D) 126 in²
Step-by-step explanation:
A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?
The formula for the surface area of a rectangular prism =
A=2(wl+hl+hw)
Where
W= Width = 5in
H = Height = 6 in
l = Length = 3 in
Surface area =
2(5 × 3 + 6 × 3 + 5 × 6) square inches
2(15 + 18 + 30) square inches
2(63) square inches
= 126 square inches (in²)
Option D is correct
Answer:
126 in 2

Answer:
Radius is 3.5 cm
Diameter is 7 cm
Step-by-step explanation:
Radius is half the diameter
They give you the diameter at 7 cm
Then you have to half that to get 3.5 cm as the radius
Answer:
The answers are the diameter is 7 because whatever the line across is it's the diameter and the radios is half of what the diameter is so whatever is half of 7 is your radios.
Step-by-step explanation:
Diameter: 7
Radios: 3.5 or 3 1/2

Answer:
answer would be (1,-1)
Step-by-step explanation:
Dialation means to multiply, so u would multiply the point where D is so in the graph it shows D is on 2, -2 so you would multiply 2 by 1/2 and -2 by 1/2 which would give you (1, -1)
ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°, what is the value of m?
6
17
90
102
Answer:
The correct answer is option B. 17
Step-by-step explanation:
It is given that, ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°
To find the value of m
From the figure we can see that, triangle WYZ is an isosceles triangle.
ZW = ZY
Then <YXZ = <WXZ = 90°
It is given ∠YXZ = (6m – 12)°
(6m – 12)° = 90°
6m = 90 + 12 = 102
m = 102/6 = 17
Therefore the value of m = 17
The correct answer is option B. 17
Answer:
its 17. so B

Answer:
30³÷(−5) = -6y²
Step-by-step explanation:
We need to find the value of the given expression :
30³÷(−5)
It can be written as :
[tex]\dfrac{30xy^3}{(-5xy)}=\dfrac{30}{-5}\times \dfrac{xy^3}{xy}\\\\=-6\times y^2\\\\=-6y^2[/tex]
So, the value of the given expression is [tex]-6y^2[/tex].

the TV Margaret wants cost $270 This week only, the TV is discounted by 25%. Margaret must pay 6% sales price. which saves the most money?
A. Taking the discount first then adding on the sales tax
B. Adding on the sales tax first and then taking the 25% discount
C. Both methods save the same amount of money
Answer:
C
Step-by-step explanation:
Method A:
270 decrease 25% =
270 × (1 - 25%) = 270 × (1 - 0.25) = 202.5
202.5 increase 6% =
202.5 × (1 + 6%) = 202.5 × (1 + 0.06) = 214.65
Method B:
270 increase 6% =
270 × (1 + 6%) = 270 × (1 + 0.06) = 286.2
286.2 decrease 25% =
286.2 × (1 - 25%) = 286.2 × (1 - 0.25) = 214.65

R.
Write your answer as an integer or as a decimal rounded to the nearest tenth.
RS =
Answer:
RS ≈ 6.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin39° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{QR}{RS}[/tex] = [tex]\frac{4}{RS}[/tex] ( multiply both sides by RS )
RS × sin39° = 4 ( divide both sides by sin39° )
RS = [tex]\frac{4}{sin39}[/tex] ≈ 6.4 ( to the nearest tenth )
Ayden and his children went into a grocery store and where they sell peaches for $0.75 each and mangos for $1.75 each. Ayden has $20 to spend and must buy no less than 16 peaches and mangos altogether. If Ayden decided to buy 7 mangos, determine the maximum number of peaches that he could buy.
Answer:
he can buy 10 peaches.
Step-by-step explanation:
7 mangoes will be 12.25. so you subtract his original money(20) from 12.25 which gives you 7.75. then divide 7.75 by 0.75(cost of a peach) and your answer will be 10(rounded off).

The sum of 6 times a number and 8 times another number is 12. The difference of those numbers is 9. What are the two numbers
Answer:
(x,y): (6 , -3) or (-30/7 , 33/7)
Step-by-step explanation:
6x + 8y = 12
x = y + 9 or y = x+ 9
if x = y+9
6*(y+9) + 8y = 12
14y = -42
y = -3 and x = 6
if y = x+9
6x + 8*(x+9) = 12
14x = -60
x = -30/7 and y = 33/7
Larry invested part of his $11,000 advance at 2% annual simple interest and the rest at 4%. If his total yearly interest from both accounts was $260 find the amount invested at each rate.
Answer:
[tex]Amount\ at\ 2 \%=9000[/tex]
[tex]Amount\ at\ 4\% =2000[/tex]
Step-by-step explanation:
From the question we are told that
Principle [tex]P=1000[/tex]
Rate 1 [tex]r_1=2\%[/tex]
Rate 1 [tex]r_2=4\%[/tex]
Total Interest [tex]I=\% 260[/tex]
Let
Amount at [tex]2 \%=x[/tex]
Amount at [tex]4\% =11000-x[/tex]
Generally the equation for the simple interest is mathematically given as
[tex]\frac{x*2*1}{100} +\frac{(11000-x)*4*1)}{100} =260[/tex]
[tex]2x+44000-4x=26000[/tex]
[tex]2x-4x=26000-44000\\[/tex]
[tex]2x=18000[/tex]
[tex]x=9000[/tex]
[tex]Amount\ at\ 2 \%=9000[/tex]
Therefore
Amount at [tex]4\% =11000-x[/tex]
Amount at [tex]4\% =11000-9000[/tex]
[tex]Amount\ at\ 4\% =2000[/tex]

The image shown is an object formed from a cylinder and spherical hemisphere. The radius of the base is 7 cm and the height of the cylinder is 10 cm
(π = 22/7). The volume of the object is ....
A. 2258,67 cm3
B. 2618,33 cm3
C. 2926,67 cm3
D. 2977,33 cm3
Answer:
Volume = 2,258.67 cm³
Step-by-step explanation:
Volume of the object = volume of hemisphere + volume of cylinder
= ⅔πr³ +πr²h
Where,
π = 22/7
r = 7 cm
h = 10 cm
Volume = (⅔*22/7*7³) + (22/7*7²*10)
Volume = 2,258.67 cm³

(5,-9);slope= -4/3
Write in slope intercept form
Answer:
y = 4/3x-7/3
Step-by-step explanation:
Slope intercept form is y=Mx+b; m=slope & b= y intercept
y=-4/3x+b
Now substitute x & y with the point given
(-9)=-4/3(5)+b
-9= -20/3+b
+20/3 +20/3
-7/3=b
Now substitute this into the original equation
y = 4/3x-7/3

what is the factored form of -4/5(30x - 40) + (42x + 4)?
Answer:
18(x + 2)
Step-by-step explanation:
-4/5 ( 30x - 40) + (42x + 4) = -24x + 32 + 42x + 4 = 18x + 36 = 18(x + 2)
Answer:
18x+36
Step-by-step explanation:
1. Simplify \frac{4}{5}(30x-40)54(30x−40) to \frac{4(30x-40)}{5}54(30x−40).
-\frac{4(30x-40)}{5}+42x+4−54(30x−40)+42x+4
2. Factor out the common term 1010.
-\frac{4\times 10(3x-4)}{5}+42x+4−54×10(3x−4)+42x+4
3. Simplify 4\times 10(3x-4)4×10(3x−4) to 40(3x-4)40(3x−4).
-\frac{40(3x-4)}{5}+42x+4−540(3x−4)+42x+4
4. Simplify \frac{40(3x-4)}{5}540(3x−4) to 8(3x-4)8(3x−4).
-8(3x-4)+42x+4−8(3x−4)+42x+4
5. Expand by distributing terms.
-(24x-32)+42x+4−(24x−32)+42x+4
6. Remove parentheses.
-24x+32+42x+4−24x+32+42x+4
7. Collect like terms.
(-24x+42x)+(32+4)(−24x+42x)+(32+4)
8. Simplify.
18x+3618x+36
