Answer 1

Answer:

4) 724

5) 750

6) 390

Step-by-step explanation:

[tex]SA_1 = 2(lw + lh + wh) = 2(17 * 14 + 17 * 4 + 14 * 4) = 2(238 + 68 + 56) = 2 * 362 = 724[/tex]

[tex]SA_2 = 2(lw + lh + wh) = 2(19 * 13 + 19 * 4 + 13 * 4) = 2(247 + 76 + 52) = 2 * 375 = 750[/tex]

[tex]SA_3 = 2(lw + lh + wh) = 2(14 * 9 + 14 * 3 + 9 * 3) = 2(126 + 42 + 27) = 2 * 195 = 390[/tex]

Line AC intersects line EB at point F. Ray FD extends from point F. Determine the measures of ∠EFD and ∠CFD.

Answers

Answer:

<EFD= 47.5°

<CFD=47.5°

Step-by-step explanation:

Seeing that 85° is already there and it would be an opposite angle to <BFC all you would have to do is subtract that 85° from 180° because that's the angle of a straight line. then when you get 95° you divide it by 2.

Efd=47.5 cfd=47.5 answer

Answer:

the answer is B : 7

Step-by-step explanation:

Answer:

B. 7

Step-by-step explanation:

According to the word problem, Muna is dividing a piece of string that 42 2/3 long into 2/3 pieces.

[tex]\frac{14}{3} /\frac{2}{3}[/tex] (changed to an improper fraction)

Whenever dividing fractions, remember this:

SAME, CHANGE, RECIPROCAL (FLIP)

KEEP THE FIRST FRACTION THE SAME

CHANGE THE DIVISION SIGN TO A MULTIPLICATION SIGN

FLIP THE SECOND FRACTION

[tex]\frac{14}{3} *\frac{3}{2} =\frac{42}{6}[/tex]

[tex]\frac{42}{6} =7[/tex]

I, therefore, believe Muna will have 7 pieces of string.

Answers

Answer:

$268.38

Step-by-step explanation:

First we will take off the 20% off the 315 dollars. SO we can do this by saying that the discounted price is 80% of the original price, (because 100 - 20 = 80). So 0.8 * 315 = 252. So 252 = discounted price. So then we have to add the tax price.

Sales tax is %6.5, so we can do 252*0.065 to find the tax payed. We get 16.38, so we can dd this to our discounted price to get 252 + 16.38, or $268.38

$268.38 is the correct answer

The length of each side of the cube shown is 5cm

Which equation can be used to find the volume of the cube
​

Answers

Answer:

5 x 5 x 5 = 5 ³ = 125 cm ³

Step-by-step explanation:

The formula for volume is l x w x h

length = 5cm

width = 5cm

height = 5cm

therefore, equation is 5 x 5 x 5 = 125 cm ³

volume = length x width x height

length-5
width-5
height-5

5 x 5 x 5 = 125 units
(p.s make sure you say 125 units cubed or put a small 3 while using volume)!

Answer:

Diameter = 7, Radius = 3.5

Radius = 9, Diameter = 18

Diameter = 12, Radius = 6

Radius = 2.5, Diameter = 5

Step-by-step explanation:

The diameter is the largest line that can be drawn in a circle. It passes from one end of the circle to another, and it goes through the center of the circle. The radius is a line drawn from the center of the circle to the circumference of a circle. By its definition, the radius will always be half of the diameter. Use this information to find the radius of the circle when given the diameter,

Diameter = 7, Radius = 3.5

Radius = 9, Diameter = 18

Diameter = 12, Radius = 6

Radius = 2.5, Diameter = 5

Diameter = 7 Radius = 3.5
Radius = 9 Diameter = 18
Diameter = 12 radius = 6
Radius = 2.5 Diameter = 5
