7.

lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²

curved surface area=2[area oftraingle]=2×1/2×4×3

=12cm²

now

total surface area=72cm²+12cm²=84cm²

8.

volume of traingular prism=area of traingle ×length

=1/2×12×3.4×4=81.6in³

Answer:

(3x+1)(x+5)

Step-by-step explanation:

Sorry for my handwriting lol hope this makes sense

Answer:

72 ft^2

Step-by-step explanation:

area = length x width

1/2 x 8 = 3

3 x 24 = 72

Answer:

56

Step-by-step explanation:

42 / 3 = brother's amount = 14

14 + 42 = 56

Answer:

Step-by-step explanation:

money of brother=x(say)

money i have=3x

x+3x=42

4x=42

x=42/4=21/2=10.50

money of brother=$ 10.50

money i have= 3 *10.50=31.50 $

Answer: [tex]7,5.66,39^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]IJ=9\\\angle I=51^{\circ}[/tex]

from figure, we can write

[tex]\Rightarrow \sin 51^{\circ}=\dfrac{HJ}{9}\\\\\Rightarrow HJ=9\sin 51^{\circ}=6.99\approx 7[/tex]

[tex]\Rightarrow \cos 51^{\circ}=\dfrac{HI}{9}\\\Rightarrow HI=9\cos 51^{\circ}\\\Rightarrow HI=5.66[/tex]

In right angle trianle, the sum of the remaining two angles is [tex]90^{\circ}[/tex]

[tex]\therefore 51^{\circ}+\angle J=90^{\circ}\\\Rightarrow \angle J=90^{\circ}-51^{\circ}\\\Rightarrow \angle J=39^{\circ}[/tex]

Answer:

10344.827586 basketballs

Step-by-step explanation:

A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?

Step 1

We find the volume of the room

The room is rectangular in shape

Volume = Length × Width × Height

= 15ft × 20ft × 10ft

= 3000ft³

Step 2

Basket ball is spherical in shape

Volume of a sphere = 4/3πr³

Diameter = 9.6 inches

Radius = Diameter/2 = 9.6 /2 = 4.8 inches

Convert Radius from inches to ft

= 4.8inches/12

= 0.408333 feet

Volume of a sphere = 4/3 × π × 0.408333³

= 0.29 ft³

Step 3

3000 ÷ 0.29

10344.827586

Answer:

option C

Step-by-step explanation:

Answer:

Step-by-step explanation:

you’re given A=0.62 and B/A=0.93

you’re solving for B

substitute your A value of 0.62

B/0.62=0.93

same as B/0.62=0.93/1

now cross multiply

B= 0.62x0.93

B=0.5766

B=0.58

Question:

Plot two points that are 8 units from Point B and also share the same x-coordinate as Point B

See attachment for grid

Answer:

See attachment for plot

Step-by-step explanation:

See comment for complete question

From the attached image, we have:

[tex]B = (-6,0)[/tex]

Required

2 points that are 8 units away and on the same x coordinate

Let the two points be [tex]C\ and\ D[/tex]

The first condition is that; C and D must be on the same x coordinate as B.

So, we have:

C = (-6,_)

D = (-6,_)

8 units from B implies that we add or subtract 8 from the y coordinate of B.

So, we have:

[tex]C = (-6,0+8)[/tex]

[tex]D = (-6,0-8)[/tex]

[tex]C= (-6,8)[/tex]

[tex]D= (-6,-8)[/tex]

Answer:

Answer:

The least common multiple of 50, 18 and 32 is 7200.

Step-by-step explanation:

mark brainleist plz

Answer:

LCM = 7200

Step-by-step explanation:

LCM(18, 32, 50) =

LCM(LCM(18, 32), 50)

Working from the innermost parentheses outward:

LCM(18,32) = (18 × 32) / GCF(18,32)

= (18 × 32) / 2

= 576 / 2

= 288

LCM(288,50) = (288 × 50) / GCF(288,50)

= (288 × 50) / 2

= 14400 / 2

= 7200

Therefore,

LCM(18, 32, 50) = 7200

Answer:

20.25 ounces

Step-by-step explanation:

We are given 2.25 ounces of cranberry poured into the container per second. We need to find is how much that is after 9 seconds. (Note: This is different from the 15.75 ounces of orange.) There are many ways to solve this question (e.g If 2.25 is 1, then multiply 2.25 and 9 = 20.25) Now to solve this let's set up fractions; let "x" be the variable;

[tex]\frac{1}{2.25}=\frac{9}{x}[/tex]

Apply fraction: if [tex]\frac{a}{b}=\frac{c}{d}\mathrm[/tex]  then [tex]a\cdot \:d=b\cdot \:c[/tex] (meaning cross multiply)

[tex]1\cdot \:x=2.25\cdot \:9[/tex]

Simplify

[tex]1 x = 2 . 2 5 \cdot 9 \\\\ x = 2 . 2 5 \cdot 9[/tex]

[tex]x = 2 . 2 5 \cdot 9\\\\x=20.25[/tex]

Therefore, there are 20.25 ounces of fruit pouch in the container after 9 seconds.

Answer:

The exam was out of 75.

Step-by-step explanation:

You know that he earned 65% so more than half his answers were correct.

Then, you would guess and check try 49/60, 49/70, and go up by 10s or 5s. You will then realize that 49÷75 equals 65.333. This rounds up to 65.

Answer:

a = 27

b = 38

c = 19

Step-by-step explanation:

a + b + c = 84

b = 2c

a = 8+c

8+c +2c+c = 84

4c + 8 = 84

4c = 76

c = 19

b = 2(19) = 38

a = 8 + 19  = 27

Answer:

x <6

Step-by-step explanation:

bots these days i swear

Answer:

19

Step-by-step explanation:

From 8-->0 =8

+ from 0--->-11=11

The shortest distance between two points is a straight line.

Use the distance formula for points.

In the diagram, we are given two points:

(4,2) and (-3,0).

Let d = distance between the two points.

d = sqrt{(-3 -4)^2 + (0-2)^2}

d = sqrt{(-7)^2 + (-2)^2}

d = sqrt{49 + 4}

d = sqrt{53}

d = 2.2360679775

d = 2.2 miles
