What shape is both a rhombus and rectangle?
A. square
B. kite
c. trapezoid
D. triangle

Answer:

C. 39

Step-by-step explanation:

If AB = BC, and angle A is 39 degrees. we can assume that angle C would have a similar angle.

Since in △ABC , AB=BC

∴ the triangle is isoceles.

In an isoceles triangle the angles opposite to equal sides are equal.

∴∠A=∠C

This means that C.39 is the correct answer

Answer:

39, C

Step-by-step explanation:

If angle A = 39, then the angle C is equal to A. This may seem like a weird question, but it’s the way that the triangle is positioned.

Also, you can prove this by looking at the equation provided in the prompt.

B is the vertex that they are creating this problem from, therefore, it may be helpful to turn the triangle around!

Answer:

60 inches

Step-by-step explanation:

Given data

We have the scale of the drawing as

1cm= 6 inches

Now if 1 cm is equivalent to 6inches

then 10cm will be x inches

Cross multiply we have

x*1= 10*6

x= 60 inches

Hence the length of the actual bed is 60inches

4/5-(-2/8)= 4/5+2/8 On taking LCM = 42/40= 21/20

Answer:

x =12

Step-by-step explanation:

The two angles add to 90 degrees

4x+4 + 5x-22 = 90

Combine like terms

9x - 18 = 90

Add 18 to each side

9x -18+18 = 90+18

9x = 108

Divide each side by 9

9x/9 = 108/9

x =12

Answer:

C.) 52°

Step-by-step explanation:

find x first

4x + 4 + 5x - 22 = 90

9x - 18 = 90

9x = 108

x = 12

plug it into the expression

4(12) + 4

= 48 + 4

= 52°

Answer:

(0, 1)

Step-by-step explanation:

First, we need to make y the subject of the formula from both expressions

For 4x+8y=5

8y = 5- 4x

y = (5-4x)/5

Similarly for x-3y= -3

-3y = -3 - x

3y = x+3

y = (x+3)/3

Since both lines intersects, hence;

(5-4x)/5 = (x+3)/3

Cross multiply

5(x+3) = 3(5-4x)

5x + 15 = 15 - 12x

5x + 12x = 15 - 15

17x = 0

x = 0/17

x = 0

Sustitute x = 0 into any of the equations

Given that y = x+3/3

y = 0+3/3

y = 3/3

y = 1

This shows that the lines intesects at (0, 1)

Answer:

Volume of the pyramid is 448 cubic meters.

Step-by-step explanation:

Volume of the given pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height of the pyramid})[/tex]

Area of the rectangular base = Length × Width

                                                = 12 × 16

                                                = 192 m²

Volume of the pyramid = [tex]\frac{1}{3}(192)(7)[/tex]

                                      = 448 m³

Therefore, the volume is 448 cubic meters.

9514 1404 393

Answer:

Step-by-step explanation:

The general approach here is to choose a variable you want to eliminate, identify the coefficients of it, and use those to multiply the equations so adding the products will eliminate the variable.

Here, the coefficients of x are -1 and -3; the coefficients of y are 2 and 5. We often like to choose the set of coefficients that includes 1 or where the coefficients are related by an integer factor. These criteria suggest that we should use the coefficients -1 and -3. One of our multipliers must be the opposite of one of these coefficients. So, we choose for them to be -3 and +1.

That is, multiplying the first equation by -3 will make the x-coefficient be 3; multiplying the second equation by 1 will make the x-coefficient be -3. Adding these equations will then eliminate x terms.

  (-3)(-x +2y = 12)

+ (1)(-3x +5y =27)

gives (3x -6y) +(-3x +5y) = -36 +27

which simplifies to the sum ...

  0x -1y = -9

__

Dividing by the coefficient of y, we find y = 9. Substituting into the first equation, we have ...

  -x +2(9) = 12)

  x = 18-12 = 6

The solution is (x, y) = (6, 9).

Answer:

x = 5

Step-by-step explanation:

Simplifying

6x + -3 = 3x + 12

Reorder the terms:

-3 + 6x = 3x + 12

Reorder the terms:

-3 + 6x = 12 + 3x

Solving

-3 + 6x = 12 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-3 + 6x + -3x = 12 + 3x + -3x

Combine like terms: 6x + -3x = 3x

-3 + 3x = 12 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + 3x = 12 + 0

-3 + 3x = 12

Add '3' to each side of the equation.

-3 + 3 + 3x = 12 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = 12 + 3

3x = 12 + 3

Combine like terms: 12 + 3 = 15

3x = 15

Divide each side by '3'.

x = 5

Answer:

Radius = √75 or 5√3 or 8.7

Step-by-step explanation:

This forms a right triangle meaning you can use Pythagorean Theorem to solve for the missing side which, in this case, will equal the radius.

Let a = radius

a² + b² = c²

a² + 11² = 14²

a² + 121 = 196

a² = 75

a = √75 = 5√3 ≈ 8.7

Answer:

radius = ab = √75

Step-by-step explanation:

Triangle ABC is a right triangle so to find the radius, aka one of the sides of the triangle, we need to use the Pythagorean theorem.

ac^2 = bc^2 + ab^2 Pythagoras Theorem

14^2 = 11^2 + ab^2 Substitution

196 = 121 + ab^2 Alg

75 = ab^2 Alg

ab = √75 Alg = radius

Answer:

Yes

Step-by-step explanation:

We can make one equation other to the other to solve for x-value first;

=> -4x = x - 5

=> -4x + (-x) = -5

=> -5x = -5

=> x = -5/-5

=> x = 1

Once we have the x-value we can substitute it in for "x" in any equation to find the y-value;

=> y = x - 5

=> y = (1) - 5

=> y = -4

Writing the answer coordinate points would look like (x, y) which would be (1, -4) which is similar to the give, there for yes the solution to the equations is the given coordinate.

Hope this helps!

Answer:

A = 20

Step-by-step explanation:

Answer:

Please be careful with your typing [f(x)=-sqrt(x)+6 ... right? g(x)=-4*sqrt(x)-3 ... or -4*sqrt(x)+3 ... one or the other, right?

If so, you are dilating by a factor of 4, -1 versus -4 as multiplier of sqrt(x); and, translating up 3 units (6 versus 3) or 9 units (6 versus -3).

Step-by-step explanation:

Answer:

-2x+2

Step-by-step explanation:

f(x) = -4x+3 and g(x) = 3 +2x-4

Note what you put for g(x) simplifies to 2x-1

(f+g) (x) =  -4x+3+  3 +2x-4

Combine like terms

            = -2x+2

Answer:

68

Step-by-step explanation:

Total mile cycled, d(t) ;

d(t) = 12t + 20

At d(4)

t = 4 ;

We have;

d(4) = 12(4) + 20

d(4) = 48 + 20

d(4) = 68

After, 4 hours of cycling, Joanna cycled a total distance of 68 miles

Answer:

12+12+4+6+26=50

12/50=6/25=0.24=24%

Answer:

1/5.

Step-by-step explanation:

First you have to add up all of the numbers: 12+12+4+6+26. Then you have to find how many red marbles there are, which this case there are 12, so you get your fraction of 12/60 which can be reduced to 1/5.

Answer:

y = -½x + 4

Step-by-step explanation:

Equation of any line in slope-intercept form is y = mx + b, where,

m = slope = change in y/change in x

b = y-intercept = the point on the y-axis intercepted by the line.

Let's find m and b.

✔️Using two points on the line, (0, 4) and (2, 3),

Slope (m) = change in y/change in x = (3 - 4)/(2 - 0)

m = -1/2 = -½

✔️The line intercepts the y-axis at y = 4.

Therefore,

b = 4

✔️To write the equation of the line, substitute m = -½ and b = 4 into y = mx + b.

Thus,

y = -½x + 4

Answer:

1st term = 14

2nd term = 29

3rd term = 44

Step-by-step explanation:

1st term = 3 x (5x 1) - 1

             = 3 x 5 - 1

             = 15 - 1 = 14

2nd term = 3 x ( 5 x 2 ) - 1

               = 3 x 10 - 1

                =30 - 1 = 29

3rd term = 3 x (5 x 3 ) - 1

               = 3 x 15 - 1

               = 45 - 1 = 44
