angle DG = ____

Answer:

A(an)   altitude    of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)

Step-by-step explanation:

AN ALTITUDE -  An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.

Hence , the answer is an altitude .

Answer:

Adults: 75, girls: 100, Boys: 75

Step-by-step explanation:

2/5 x 250 = 100( girls)

3/10 x 250 = 75 (boys)

250 - (100 + 75) = 250 - 175 = 75 (Adults)

Answer:

I believe the answer is 3/10

Step-by-step explanation:

Or do you need the number of adults or fraction? The number of adults is 75

Answer:

16 liters

Step-by-step explanation:

40 liters ÷ 30 mins = 1.333333... liters

1.3333333... liters x 12 mins = 16

Answer:

= 16 litres of water

Step-by-step explanation:

30 mins = 40 litres

15 mins = 20 litres

3 mins = 4 litres

12 mins = 16 litres

Answer:

87.55 [tex]cm^2[/tex]

Step-by-step explanation:

Answer:

Slope = 2/7

y-intercept = 0

Proportional = yes

It is proportional since we require no additional terms to get y from x and we can multiply each x term by a certain factor to get the y values

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and b is the y-intercept

From what we can see, the slope of the given line is 2/7

As we can see, there is no y-intercept; so the y-intercept value is 0

As we can see, we can multiply each x value by 2/7 to get the corresponding y-value

What this mean is that both variables are proportional

Answer:

The formula for the volume of a triangular prism is:

V=(l)(w)(h)

Where l is the length of the triangle, w is the width of the triangle, and h is the height of the prism

The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.

Answer:

35 marbles were blue

Step-by-step explanation:

42/6 = 7

7 x 5 = 35

Answer:

large = 12

medium = 18

Step-by-step explanation:

L + M = 30 => L = 30-M

4L+3M =102

substitute : L with M

=> 4(30-M)+3M =102

120-4M+3M = 102

- M = 102-120

-M = -18

=========> M = 18, L = 12

Answer:

Solution given.

centre (h,k):(-6,1)

radius (r)=2

we have

equation of a circle is:

(x-h)²+(y-k)²=r²

(x+6)²+(y-1)²=2²

(x+6)²+(y-1)²=4 is a required equation of a circle.

Given:

[tex]a_n[/tex] is an arithmetic sequence.

To find:

The value of [tex]\dfrac{1}{a_1a_2}+\dfrac{1}{a_2a_3}+...+\dfrac{1}{a_{39}a_{40}}[/tex].

Solution:

We have,

[tex]\dfrac{1}{a_1a_2}+\dfrac{1}{a_2a_3}+...+\dfrac{1}{a_{39}a_{40}}[/tex]

It can be written as:

[tex]=\dfrac{d}{d}\left[\dfrac{1}{a_1a_2}+\dfrac{1}{a_2a_3}+...+\dfrac{1}{a_{39}a_{40}}\right][/tex]

[tex]=\dfrac{1}{d}\left[\dfrac{d}{a_1a_2}+\dfrac{d}{a_2a_3}+...+\dfrac{d}{a_{39}a_{40}}\right][/tex]

[tex]=\dfrac{1}{d}\left[\dfrac{a_2-a_1}{a_1a_2}+\dfrac{a_3-a_2}{a_2a_3}+...+\dfrac{a_{40}-a_{39}}{a_{39}a_{40}}\right][/tex]

[tex]=\dfrac{1}{d}\left[\dfrac{1}{a_1}-\dfrac{1}{a_2}+\dfrac{1}{a_2}-\dfrac{1}{a_3}+....+\dfrac{1}{a_{39}}-\dfrac{1}{a_{40}}\right][/tex]

[tex]=\dfrac{1}{d}\left[\dfrac{1}{a_1}-\dfrac{1}{a_{40}}\right][/tex]

[tex]=\dfrac{1}{d}\left[\dfrac{a_{40}-a_1}{a_1a_{40}}\right][/tex]

[tex]=\dfrac{1}{d}\left[\dfrac{a_1+(40-1)d-a_1}{a_1a_{40}}\right][/tex]       [tex][\because a_n=a_1+(n-1)d][/tex]

[tex]=\dfrac{1}{d}\left[\dfrac{39d}{a_1a_{40}}\right][/tex]

[tex]=\dfrac{39}{a_1a_{40}}[/tex]

Therefore, the value of given expression is [tex]\dfrac{39}{a_1a_{40}}[/tex].

Answer:

Problem 1:

Width of the larger version = 2.99 in.

Problem 2:

Friday = 5⅞ miles

Step-by-step explanation:

Problem 1:

Since the cell-phones are similar in shape and the width and length of both are proportional, therefore:

Width of the bigger phone/Width of the smaller phone = length of the bigger phone/length of the smaller phone

Width of smaller phone = 2.6 in.

Length of smaller phone = 5.4 in.

Width of bigger phone = x = ? in.

Length of bigger phone = 6.21 in.

Therefore:

6.21/5.4 = x/2.6

Cross multiply

5.4 × x = 2.6 × 6.21

5.4x = 16.146

Divide both sides by 5.4

x = 16.146/5.4

x = 2.99

Width of the larger version = 2.99 in.

Problem 2:

Jen's goal for the 5 days = 22 miles

The number of miles she ran Mon to Thursday was given.

To meet her goal, let's find the number of miles she has to run to meet her goal.

Thus:

Number of miles to run on Friday = 22 - (4¾ + 5⅛ + 0 + 6¼)

Change to improper fraction

= 22 - (19/4 + 41/8 + 0 + 25/4)

= 22 - ((38 + 41 + 0 + 50)/8)

= 22 - 129/8

= (176 - 129)/8

= 47/8

= 5⅞ miles

Answer:

x=19

Step-by-step explanation:

okay so all those angles there are pretty simple. because of the vertical angles theorem, the angles that go across from each other are equal to each other. On a thing like this those intersections are congruent. So knowing this we can assume that (6x+4)=118. so if you solve the basic algebra for that (you can use mathpapa or smt if you really need the work for that) then it comes out as x=19 which you can check.

6x+4=118

subtract 4 from both sides

6x=114

divide by 6 on both sides

x=19

Hope this helps!
