Answer:

Since BD Bisects ABC,

Hence,

Angle CBD=Angle DBA

-> 55°=x°+12°

-> x° =55°-12°

-> x° =43°

Step-by-step explanation:

a) There's a mistake at the third step from the beginning.

b) Instead of adding 25 , Josh added 100. While solving an equation using "Completing Squares Method" , we need to write the L.H.S. in the form of  [tex]a^{2} + 2ab + b^{2}[/tex]  or  [tex]a^{2} - 2ab + b^{2}[/tex] , so that in the next step it can be converted into [tex](a + b)^{2}[/tex] or [tex](a - b)^{2}[/tex].

c) [tex]x^{2} + 10x - 88 = 8[/tex]

Taking -88 to R.H.S. , it's sign changes and becomes +88.

[tex]=> x^2 + 10x = 88 + 8 = 96[/tex]

Using "Completing Squares Method" , L.H.S.  can be written as :-

[tex](x)^{2} + 2 \times x \times 5 + (5)^{2} = 96 + (5)^{2}[/tex]

[tex]=> (x + 5)^{2} = 96 + 25 = 121[/tex]

[tex]=> x + 5 = \sqrt{121} = -11 \: or +11[/tex]

[tex]=> x = +6 \: or -16[/tex]

Answer:

I think it may be 120 cm

Step-by-step explanation:

A F is 13 using pythagorean theorem on triangle CED and applying the hypotenuse length to A F.

ABC is similar to triangle CED and is dilated by a factor of 3  so the base is 36.

using pythagorean theorem on triangle ABC gets the hypotenuse length of 39 which can be applied to FE

add all the values together

39 + 13 + 15 + 36 +12 +5 = 120

Answer:

[tex](a)[/tex] [tex]Length= 3cm[/tex]   [tex]Width = 6cm[/tex]   [tex]Area = 24cm^2[/tex]

[tex](b)[/tex] [tex]Length= 3cm[/tex]   [tex]Width = 8cm[/tex]     [tex]Area= 24cm^2[/tex]

Step-by-step explanation:

Given

See attachment for rectangle

Solving (a):

From the first rectangle, there are 6 columns and 3 rows.

This implies that:

[tex]Length= 3cm[/tex]

[tex]Width = 6cm[/tex]

So, the area is:

[tex]Area = Length * Width[/tex]

[tex]Area = 3cm * 6cm[/tex]

[tex]Area = 18cm^2[/tex]

Solving (a):

From the first rectangle, there are 3 rows and the total area is 24.

This implies that:

[tex]Length= 3cm[/tex]

[tex]Area= 24cm^2[/tex]

Area is:

[tex]Area = Length * Width[/tex]

[tex]24cm^2= 3cm * Width[/tex]

Make Width the subject

[tex]Width = \frac{24cm^2}{3cm}[/tex]

[tex]Width = 8cm[/tex]

Answer:

P=75.922 ≈ 76

∘Step-by-step explanation:

What function uses the ADJACENT and the HYPOTENUSE?

SOH-CAH-TOA

cos P = adjacent/hypotenuse= 1.8/7.4

Pcos^-1 = (1.8/ 7.4)

​

P=75.922 ≈ 76

The measure of ∠H in the ΔHIJ to the nearest tenth is 18.4 ft.

Right angle triangle are triangles that have one of its angles as 90 degrees. The sides can be found using trigonometric ratios. Therefore, the measure of ∠H can be found as follows:

tan ∠H = opposite / adjacent

tan ∠H = 3.2 / 9.6

Therefore,

∠H = tan⁻¹ 0.33333333333

∠H = 18.434948651

∠H = 18.4 ft

Therefore, the value of ∠H to the nearest tenth is 18.4 ft

Answer:

∠x = 50°

Step-by-step explanation:

arc opposite angle x = 130°    (360° - 30° - 100° - 100° = 130°)

∠x = 1/2(130 - 30)              (angles formed by secants theorem)

∠x = 50°

Answer:

She made 32 free throw shots.

Step-by-step explanation:

Based on the given information, one can form the general equation;

[tex]\frac{made}{missed}[/tex]

Substitute in the given values;

[tex]\frac{4}{3}[/tex]

Assuming that the rates at which this proportion exists is constant, and one knows the number she missed, but not the number she made then one can say;

[tex]\frac{made}{missed}= \frac{4}{3} = \frac{made}{24}[/tex]

Solve the proportion using cross products;

[tex]\frac{4}{3}=\frac{made}{24}\\\\\\(4)(24)=(3)(made)\\\\96=3made[/tex]

Inverse operations,

[tex]96=3made\\/3\\\\32=made[/tex]

Answer: $52.50

Step-by-step explanation:

There is $50 in the account and it earns interest at a rate of 5% a year.

This interest is not compounded therefore it is simple interest.

To calculate amount earned with simple interest is:

= Deposit * ( 1 + rate * time)

= 50 * ( 1 + 5% * 1 year)

= $52.50

Answer:

By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons.

Step-by-step explanation:

Given

f(x) = 10^x

Now

LHS

f(a + b + c)

= 10^ a + b + c

RHS

f(a) • f(b) • f(c)

= 10^a • 10^b • 10^ c

= 10 ^ a + b + c

Therefore LHS = RHS

Answer:

Stefan spent $120 originally

He made $24 dollars by selling the bicycle and helmet to Jin

Step-by-step explanation:

First, find the total cost:

127 + 17

= 144

To find the original cost, divide this by 1.2

144/1.2

= 120

So, Stefan spent $120 originally.

Now, find how much he made by subtracting 120 from 144:

144 - 120

= 24

So, he made $24 dollars by selling the bicycle and helmet to Jin.

Answer:

f(x) = x³ - 2x² - 19x + 20

Step-by-step explanation:

Given a polynomial with zeros x = a, x = b then the corresponding factors are

(x - a)(x - b) and the polynomial is then the product of the factors

Given zeros x = 5, x = - 4, x = 1 , then

(x - 5), (x + 4) and (x - 1) are the factors, then

f(x) = (x - 5)(x + 4)(x - 1) ← expand the first pair of factors using FOIL

     = (x² - x - 20)(x - 1) ← distribute

     = x³ - x² - 20x - x² + x + 20 ← collect like terms

     = x³ - 2x² - 19x + 20

Answer:

Tank which is capable of holding 1 can fill each one of the tanks an exact number of time.

Step-by-step explanation:

Three tanks are capable of holding [tex]361,841,901[/tex]

To find which tank can be used to fill each one of them an exact number of time, find [tex]HCF(361,841,901)[/tex]

[tex]361=19^2\\841=29^2\\901=17(53)[/tex]

Therefore,

[tex]HCF(361,841,901)=1[/tex]

So, tank which is capable of holding 1 can fill each one of the tanks an exact number of time.
