Answer:

Step-by-step explanation:

If the question asks for volume, then

---> 7 x 5 x 3 = 105

If it asks for surface area

---> 2(wl+hl+hw)=

2(7 x 5 + 7 x 3 + 5 x 3)=

142

If it asks for area of the base then the answer is

7 x 3 = 21

in the figure below, what are the values of x and y? What are the measures of the four angles in the figure

snow_tiger [21]

Answer:

a. x=57.6, y=44.8

Step-by-step explanation:

Named the angles, check the picture for that

<ABD+<ACD=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)

<CAB+<BDC=180 (Opposite angles of a quadrilateral is supplementary (180 degrees)

therefore:

a. 3y+x-12=180.............. equ 1

2x+y+20=180.............equ 2

From equ 1

x+3y=180+12

x+3y=192...............equ 3

From equ 2

2x+y=180-20

2x+y=160.............equ 4

Equate equ 3 and equ 4

x+3y=192...............equ 3

2x+y=160.............equ 4

Using elimation method

x+3y=192...............equ 3

2x+y=160.............equ 4

Multiple equ 3 by 1 and equ 4 by 3

x+3y=192...............equ 3 ×1

2x+y=160.............equ 4 ×3

x+3y=192

6x+3y=480

Subtract

-5x+0=-288

-5x=-288

x=57.6................... Equ 5

Replace 57.6 for x in equ 3

x+3y=192...............equ 3

57.6+3y=192

3y=192-57.6

3y=134.4

y=44.8

B. <CAB= 2x=2×57.6=115.2

<ABD= 3y=3×44.8= 134.4

<ACD=x-12=57.6-12=45.6

<BDC=y+20=44.8+20=64.8

At big bens bakery 48 chocolate donuts were made,which is 6 times the number of cream filled donuts made.How many more chocolate

ratelena [41]

Answer:

The number of chocolate made donuts is 40 more than cream filed donuts

Step-by-step explanation:

Given as :

The number of chocolate donuts made = 48

The number of chocolate donuts is 6 times the number of cream filled donuts

So, Let the number of cream filled donuts = x

So, number of chocolate donuts made = $6\times x$

∴ $6\times x$ = 48

Or, x = $\frac{48}{6}$ = 8

So, the number of cream filled donuts = 8

Now ,

The number of chocolate donuts made - the number of cream filled donuts = 48 - 8 = 40

So , The number of chocolate made donuts is 40 more than cream filed donuts Answer

Need help asap !!!!!

Romashka [77]

Answer:

The answer is x = 5.

Step-by-step explanation:

Given:

Δ ABC is an Isosceles triangle with AB = CA

m∠ ABC = ( 6x + 4 )°

m∠ BAC = 73°

m∠ BCA = ( 8y - 7 )°

To Find:

x = ?

Solution:

Properties of an Isosceles Triangle.

Base angles or two angles are equal.
Any two sides are equal.

Here , Δ ABC is an Isosceles triangle with AB = CA

∴ m∠ BAC = m∠ BCA

$73= 8y-7\\8y=73+7\\8y=80\\y=\frac{80}{10} \\y=10$

∴ m∠ BCA = ( 8y - 7 )°

= 8 × 10 - 7

m∠ BCA = 73 Which is same as ∠ CAB

Property of a Triangle is Sum of the measures of the angle of a triangle is 180°.

$\angle ACB + \angle CAB + \angle CBA = 180$

Substituting the values we get,

$73 + 73 + (6x+4) = 180\\6x+4=180-146\\6x=34-4\\6x=30\\x=\frac{30}{6} \\x=5\\$

The answer is x = 5.
