abc is isosceles triangle above is ac=20 and bc=3x-7 what is x

Answers

Answer 1

Answer:

x = 9

Step-by-step explanation:

Isosceles means that the two sides equal each other

As such, to find the value of x we must equal the two expressions together and isolate the variable

20 = 3x - 7

add 7 to both sides

27 = 3x

divide both sides by 3

9 = x

Answer 2

Answer:

The variable x equals 9.

Step-by-step explanation:

3x - 7 = 20

3x = 27

X = 9

Steve has 12 biscuits in a tin.
There are 7 digestive, 2 chocolate and 3 ginger biscuits.
Steve takes two biscuits at random from the tin.
Work out the probability that he chooses two different types of biscuits.

Answers

Answer:

There are two patterns to chose two different biscuits; a digestive then a chocolate or a chocolate and then a digestive.

The probability of choosing a digestive then a chocolate is as follows:

7/12 * 5/11 =0.265

The probability of choosing a chocolate then a digestive is as follows:

5/12*7/11 = 0.265

Therefore the combined probability is 0.53 or 53%

Probability of digestive and chocolate

7/12×2/11=14/132=7/66

And

2/12×7/11=7/66

Probability of digestive and ginger

7/12×3/11=21/132=7/44

And

3/12×7/11=7/44

Probability of ginger and chocolate

2/12×3/11=6/132=3/66=1/22

Addison can eliminate $25 from Food/Clothes and $22 from Entertainment. D. The minimum payment is enough to pay off the balance within 24 months.

Answers

Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

It is given that

Addison has a balance of $3,450 on her credit card.

APR = 18%

Current monthly payment = $86.25

She wants to choose a monthly payment for 24 months.

So for 24 months,

A revised monthly payment using formula,

[tex]M = \frac{P.\frac{R}{12}. (1+\frac{R}{12} )^N }{(1+\frac{R}{12})N -1}[/tex]

R = 0.18

P = 3450

N = 24

Revised montly payment M = $172.24

Current monthly payment = $86.25

Difference = $86

So, she needs to cut the expenses by  $86

If she cut $45 from Food/Clothes and $41 from Entertainment, she can easily pay the revised monthly payment.

Therefore, Addison needs to cut $45 from Food/Clothes and $41 from Entertainment, to pay the revised monthly payment.

m = 5

n = 5

Step-by-step explanation:

Note that the ∑ of the interior angles of a triangle = 180°.

A square for one of the angles constitute as 90°.

This means that this is a isosceles triangle.

Note that for isosceles triangles, the sides will follow the rule of 1 , 1 , √2, in which √2 is the hypotenuse.

The hypotenuse is the side opposite of the greatest angle measurement. It is given that the hypotenuse for the given triangle is 5√2. Divide √2 from the given measurement to get the measurements for the legs:

[tex]\frac{5\sqrt{2} }{\sqrt{2} } = 5[/tex]

Again, as it is a isosceles triangle, the two sides will share the same measurement.

Answers:

Compound inequality:  1 < x < 6Graph: Open hole at 1 and 6, shading in between (see diagram below)Interval notation:  (1,6)

=============================================

Work Shown:

3 < 2x+1 < 13

3-1 < 2x+1-1 < 13-1 .... subtract 1 from all sides

2 < 2x < 12

2/2 < 2x/2 < 12/2 ... divide both sides by 2

1 < x < 6

The value of x is between 1 and 6, excluding both endpoints.

Since we exclude both endpoints, the graph will have open holes at 1 and 6 on the number line. The shading is between the open holes. The graph is below.

Converting 1 < x <6 to interval notation leads to (1, 6)

The curved parenthesis in interval notation indicate "exclude the endpoint".

Using the fact that cos(52) = 0.6157, find the measure of angle B if sin(B) = 0.6157.

Answers

Answer:  B = 38

===============================================

Work Shown:

If cos(A) = sin(B), then A+B = 90, where A & B are both acute angles in degree form.

In this case, A = 52, so,

A+B = 90

B = 90-A

B = 90-52

B = 38

Telling us that

cos(A) = cos(52) = 0.6157

sin(B) = sin(38) = 0.6157

cos(52) = sin(38)

What is the width of the prism?
2 ft
w
4 ft
Volume = 24 cubic feet

Answers

Answer:

3 ft

Step-by-step explanation:

(I assumed that this was a rectangular prism based on the dimensions given, but do correct me if I assumed incorrectly.)

The formula for finding the volume of a rectangular prism is: [tex]V=w*h*l[/tex]

In this case, we already know that the volume of the prism is 24, so we can plug 24 in for V:

[tex]24=w*h*l[/tex]

We also already know the height and the length because they gave it to us, so we can plug it in as follows:

[tex]24=w*2*4[/tex]

Then we can multiply 2 and 4 on the right side:

[tex]24=w*8[/tex]

Then, to get the w alone, we can divide by 8 on both sides:

[tex]3=w[/tex]

Now that gives us that the width of the rectangular prism is 3ft.
