Step-by-step explanation:

∠ BSR + ∠ TSB = ∠ TSR , substitute values

2x + 17 + 5x + 15 = 102 , that is

7x + 32 = 102 ( subtract 32 from both sides )

7x = 70 ( divide both sides by 7 )

x = 10 → B

In ∆ABC the angle bisectors drawn from vertices A and B intersect at the point D. Find m∠ADB if: m∠A = α, m∠B = β

Answers

The angle at D which is m∠ADB is calculated to be 180 - ( α + β ) / 2

How to find < ADB

Given data

< A = α

∠ B = β

Angle bisectors divides the given angle into two and form a triangle which is ∆ADB

The angles that form ∆ADB are as follows

< A = α / 2

∠ B = β / 2

to find < D we use sum of angles in a triangle which is 180 degrees and solve as follows

< A + < B + < D = 180 degrees

where < D = m∠ADB, substituting the other values gives

α / 2 + β / 2 + < D = 180

( α + β ) / 2 + < D = 180

< D = 180 - ( α + β ) / 2

Since < D = m∠ADB .We can therefore say that m∠ADB = 180 - ( α + β ) / 2

Bart found 20 quadrilaterals in his classroom. He made a Venn diagram using the properties of the quadrilaterals, comparing those with four equal side lengths (E) and those with four right angles (R). Circles E and R overlap. Circle E contains 3, circle R contains 6, and the intersection contains 2. Number 9 is outside of the circles. Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four equal side lengths? Express your answer in percent form, rounded to the nearest whole percent. 25% 33% 40% 67%

Answers

Answer:

A. 25%

Step-by-step explanation:

The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is 25%

What are quadrilaterals?

Quadrilaterals are shapes that have four sides; these four sides may or may not be:

ParallelCongruent

Check below on how to determine the probability

From the question, we have the following parameters:

n(E) = 5n(R) = 8n(E and R) = 2None = 9n(U) = 20

The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is calculated using:

P(E | R) = n(E and R)/n(R)

This gives

P(E | R) = 2/8

Express as percentage

P(E | R) = 25%

Hence, the probability is 25%

I think the answer maybe be 10 miles. If he rowed upstream, that is four, and it took only one hour. Downstream he went 6 mph. We dont know how long he spent each way, so it might be cut evenly in half. Saying he spent one hour too and fro, the answer would be ten because all we have to do is add 4 and 6. This may be completely wrong, but there isn’t that much context.

Express the number 100 as a product of its prime factors.

Answers

Answer:

So, the prime factors of 100 are written as 2 x 2 × 5 x 5 or 22 x 52, where 2 and 5 are the prime numbers. It is possible to find the exact number of factors of a number 100 with the help of prime factorisation. The prime factor of the 100 is 22 x 52. The exponents in the prime factorisation are 2 and 2.

Step-by-step explanation:

Answer:

The prime factorization of 100 is 2 * 2 * 5 * 5. Using exponents, this number can also be written as 2^2 * 5^2.

HELPPPP FIND VALUE OF Y !!!

Answers

Answer:

Y=13

Step-by-step explanation:

X is 45 so

45+5y+5=9y-2 solve and y=13

Answer:

y = 13

Step-by-step explanation:

x + 135 = 180 {linear pair}

x = 180 - 135

x = 45

9y - 2 = 5y + 5 + x {Exterior angle property of triangle}

9y - 2 = 5y + 5 + 45

9y - 2 = 5y + 50 {Subtract 5y from both sides}

9y -5y -2 = 50

4y - 2 = 50 {Add 2 to both sides}

4y = 50 + 2

4y = 52 {Divide both sides by 4}

y = 52/4

y = 13

Answer:

Step-by-step explanation:

Jordan is starting to save $150 to buy a new cell phone. In December, he saved $5. In January, he plans twice as much as he did in December, for a total savings of $15 ($5 + $10). If Jordan continues to save twice as much he saved from the previous month, in which month will his total savings will be enough to buy the phone.

Answers

Answer: At the Month May Jordan as able to get enough money to buy the phone.

Work:

December:$5

January:$10

February:$20

March:$40

April:$80

May:$160 <--Answer

____________________________________________________________In the problem Jordan saves $5 at December, then at January Jordan saved $10 which is twice as December's saved money amount. February, Jordan saved $20, which is twice as January's saved money amount. March is $40, which is twice as February's saved money amount. For April it is $80, which is twice as March's money amount, May is $160 which is twice as April's money amount. Or another way to say this is by starting at $5. Then, keep multiplying by 2 for each month until you get $150 or more. When you do, stop at the month that gets you $150 or more. When i did this exact method, I got $160 on the Month of May. $160 is more than enough for Jordan to buy his phone. So the month May is the correct answer where Jordan can get enough money for his phone.

Answer: The fifth month; By April Jordan would have saved more than enough to buy a new phone.

Step-by-step explanation:

Dec $5

Jan $10

Feb $20

Mar $40

Apr $80

Dec + Jan = $15($5+$10)

Dec+ Jan + feb = $35($5+$10+$20=$35)

Dec+ Jan + feb + mar = $75 ($5+$10+$20+$40=$75)

Dec+ Jan + feb + mar + apr = $155

($5+$10+$20+$40+$80=$155)

1) 4(0.1y + 5)

1) 0.4y + 20

2) 1.8h + 3

Step-by-step explanation:

1) 4(0.1y + 5) = 0.4y + 20

Multiply (4) to (0.1y) and then multiply (4) to (+5).

2) 0.6(3h + 5) = 1.8h + 3

Multiply (0.6) to (3h) and then multiply (0.6) to (+5).

C: -0.8x - 4.8y + 4
D: 0.8x + 4.8y + 4

Answers

Answer:

-0.8x+4.8y+16

Step-by-step explanation:

[tex]4(0.5x+2.5y-0.7x-1.3y+4)\\4(-0.2x+1.2y+4)\\4(-0.2x)+4(1.2y)+4(4)\\-0.8x+4.8y+16[/tex]

The answer would be A. Even without solving the entire thing you can the first part will be negative when you combine like terms. The second part (aka y) would be positive after the terms are combined. 16 comes from 4 multiplied by 4 after distribution.

What is composition of functions?

Composition of function is an operation in which we combine two or more function to generate a single function. In this question the function g is places in the place of x.

How to solve?

Given f(x)=x/5 +3

g(x)=10[tex]x^{2}[/tex] + 5

the composition of function ,

fg(x) = g(x)/5 + 3

fg(x) = (10[tex]x^{2}[/tex] + 5)/5 + 3

= 2[tex]x^{2}[/tex]+ 1 + 3

= 2[tex]x^{2}[/tex] + 4

hence, fg(x)= 2[tex]x^{2}[/tex]+4 where a=2 and b=4
