Answer:

-3 1/7

Step-by-step explanation:

The required simplified mixed number of -24 divided by 7 is -3 3/7.

To divide -24 by 7, the result is a mixed number in simplified form.

Divide -24 by 7:

-24 ÷ 7 = -3.428571...

Simplify the result as a mixed number:

To write the mixed number, we take the whole number part, which is -3, and the fractional part, which is the remainder after dividing.

The remainder is approximately 0.428571... (it goes on infinitely), but we'll round it to the nearest fraction for simplicity.

Approximately, 0.428571... is closest to 3/7.

So, the simplified mixed number is -3 3/7.

Answer: 280 for number 2

Step-by-step explanation: I think I ain’t not % sure

Answer:

Explanation:

3x + 5 + 3x + 4 + 3x + 9 = 180

(3x + 3x + 3x) + (5 + 4 + 9) = 180( Combine Like Terms)

9x + 18 = 180

9x + 18 = 180

9x + 18 − 18 = 180 − 18

9x = 162

Divide Both Sides By 9

9x / 9 = 162 / 9

Answer:  The dimensions of the rectangle are 7 cm × 4 cm

Step-by-step explanation:

let,

Breadth of the rectangle (l) = x

Length of the rectangle (b) = x + 3

Area of the rectangle = 28 cm²

Area of the rectangle = l × b

⇒ (x) × (x + 3) = 28

⇒ x² + 3 x = 28

⇒ x² - 3 x - 28 = 0  

⇒ x² - 7 x + 4 x - 28 = 0

⇒ (x - 7) + 4(x - 7) = 0

⇒ (x - 7)(x + 4) = 0

⇒ x = 4

Breadth = 4 cm

Length -

⇒ 4 + 3

⇒ 7 cm

Step-by-step explanation:

Answer:

Step-by-step explanation:

given tanB= 4/3

so sinB=4/5

n cosB=3/5

given BC=15

BA=BC*cosB

=15*3/5

=9

AC=BC*sinA

=15*4/5

=12

Triangle ABC and DBE are similar by AAA

DB= BA-AD

=9-3

=6

DB/BA=DE/AC

6/9=DE/12

DE=12*6/9

=8

Answer:

DE = 8

Step-by-step explanation:

ΔABC and ΔDBE are similar.

As they share the same angles, the sides are in proportion to each other.

Therefore, we can solve using ratios.

Tan trigonometric ratio

[tex]\sf \tan(\theta)=\dfrac{O}{A}[/tex]

where:

Given:

  [tex]\sf \tan (B)=\dfrac{4}{3}[/tex]

Therefore:

[tex]\implies \sf \dfrac{DE}{BD}=\dfrac{AC}{BA}=\dfrac{4x}{3x}[/tex]

We know that BC = 15 and that AC : BA = 4x : 3x

Using Pythagoras' Theorem:

[tex]\implies \sf (3x)^2+(4x)^2=15^2[/tex]

[tex]\implies \sf 9x^2+16x^2=225[/tex]

[tex]\implies \sf x^2(9+16)=225[/tex]

[tex]\implies \sf x^2=9[/tex]

[tex]\implies \sf x=3[/tex]

Therefore,

⇒ AC = 4 · 3 = 12

⇒ BA = 3 · 3 = 9

Now we have found the length of BA, we can find the length of BD:

⇒ BD = BA - DA

⇒ BD = 9 - 3

⇒ BD = 6

As DE : BD = 4x : 3x  and  BD = 6 then:

⇒ 3x = 6

⇒ x = 2

Therefore, to find DE, substitute x = 2:

⇒ DE = 4x

⇒ DE = 4(2)

⇒ DE = 8

39 degrees

Step-by-step explanation:

The sum of angle in the triangle ABC is a80 degrees

m<ACB + <BAC + <ABC =1 80

90 + <BAC + 51 = 180

141 + m<BAC = 180

m<BAC = 180-141

m<BAC = 39 degrees

Hence the measure of m<BAC is 39 degrees

Answer:

Step-by-step explanation:

Distribute the negative sign to turn the equation into pure addition. Then, change the denominator of the two fractions to the same thing.

Multiply 12/11 by 3/3

[tex]\frac{12}{11}*\frac{3}{3}=\frac{36}{33}[/tex]

Multiply 2/3 by 11/11

[tex]\frac{2}{3}*\frac{11}{11} =\frac{22}{33}[/tex]

Add them together now
