Answer:

Step-by-step explanation:

BALTIMORE  It was not an overt incident of racism that prompted Edray Goins, an African-American mathematician in the prime of his career, to abandon his tenured position on the faculty of a major research university last year.

The hostilities he perceived were subtle, the signs of disrespect unsp_ken.

And at the recent math meeting, where Dr. Goins delivered a keynote address titled “A Dream Deferred: 50 Years of Bl_cks in Mathematics,” his presence kindled conversations about racial slights in the math world. The presumption of competence and authority that seems to be automatically acc0rded other mathematicians, for instance, is often not applied to them, several bl_ck mathematicians said.

Answer:

30 ft

Step-by-step explanation:

Hi!

So according to the Pythagorean theorem, a^2 + b^2 = c^2

Ok, so let's just plug those numbers in:

18^2 + 24 ^ 2 = c^2

324 + 576 = c^2

900 = c^2

[tex]\sqrt{900}[/tex] = c

[tex]\sqrt{900}[/tex] = 30

x = 30

You could also use Pythagorean triples, and there are Pythagorean triples for this which is 3:4:5; and since it's a ratio, we can write it as 3x:4x:5x. Then, according to a and b, x would equal 6, so then we plug in x:

3(6):4(6):5(6)

and you get:

18:24:30

Answer:

About 31 days

Step-by-step explanation:

Since he already has $125, you can subtract that amount from how much he needs to earn. $400 - $125 = $275 that he must earn.

Divide the remaining amount by how much he earns a day to find the number of days he must work to reach his goal.

$275 ÷ $9 ≈ 30.5 (I got 30.5 repeating). I rounded up to 31 days.

The sample space

 = { HHH,HHT,TTT,THH,TTH,THT,HTH,HTT}

n(S) = 8

Step-by-step explanation:

Explanation:-

A referee flips a coin three times.

Let 'S' be the sample space

HHH → Three tosses has Heads

HHT → → first toss head , the second toss head and the third toss was tail

TTT→  Three tosses has tails

THH→ first toss one tail , the second toss head and the third toss was head

TTH → first toss one tail , the second toss Tail and the third toss was head

THT → first toss one tail , the second toss Head and the third toss was Tail

HTH→ first toss one head , the second toss Tail and the third toss was head

HTT→ first toss head , the second toss Tail and the third toss was tail

The sample space

 = { HHH,HHT,TTT,THH,TTH,THT,HTH,HTT} = 8

Answer:

D. {TTT, TTH, THT, THH, HTT, HTH, HHT, HHH}

Answer:

C. 21 pennants

Step-by-step explanation:

35-28=7

7 divided by 1/3= 21/1 or 21

The number of pennants that can be made is given by equation A = 49 pennants

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the number of pennants required be represented as A

The amount of fabric bought by students = 28 yards

The amount of fabric required by each pennant = 1/3 yards

The total number of pennants made by students = 35 pennants

So , the number of pennants that can be made is N

N ( 1 / 3 ) = 28 be equation (1)

Multiply by 3 on both sides , we get

N = 84 pennants

So , the remaining number of pennants A = N - number of pennants made by students

On simplifying the equation , we get

The remaining number of pennants A = 84 - 45

The remaining number of pennants A = 49 pennants

Hence , the number of pennants is 49

Answer: 6

Step-by-step explanation:

Let use the subsitution method . Look at 11=x+y let get y on the side by itself. 11=x+y 11-x=y Then we are going to subsitute 11-x for y in the top equation so it look like 20.00=2.50x+1.00(11-x). 20.00 =2.50x+11-x. Let simplify and we get 1.50x+11=20. Subtract 11 from both sides we get 1.50x=9. Divide 1.5 by 9 and we get  x= 6.

Answer: All real numbers greater than or less than 9.

Step-by-step explanation:  The range is possible y-values. In a parabola the range starts at a particular place then it either goes up or goes down. Since the leading factor has a negative in front of it, the parabola will open downward meaning most likely all y-values will be lest than the include max point. Now let find the max point using the formula -b/2a then substituting that into the parabola. -2/2(-1)= 1, then plug it in. y=-(1^2)+2(1)+8 which equal -1+2+8 which equal 9 so the max point is 9. Since the graph open downward all the points that are possible will either be at 9 or below it so the range is All  real numbers greater than or less than 9. or (-∞,∞)∪(∞,9]

Answer:

y = -8x + 0

Step-by-step explanation:

✔️First, find the rate of change/slope (m) using two pairs from the table, (3, -24) and (4, -32):

m = ∆y/∆x = (-32 -(-24))/(4 - 3)

m = -8/1

m = -8

✔️Find the y-intercept (b) by substituing (x, y) = (3, -24) and m = -8 into y = mx + b

-24 = -8(3) + b

-24 = -24 + b

-24 + 24 = b

b = 0

✔️Write the equation by substituting m = -8 and b = 0 into y = mx + b

y = -8x + 0

(12 ÷ 4) × (18 ÷ 6)

Step-by-step explanation:

(12 ÷ 4) × (18 ÷ 6)

If we solve this or simply this, we would get 9 as our result.

Let's solve and see. Mind you, we've used each of the given numbers just once in the expression.

Thus:

(12 ÷ 4) × (18 ÷ 6)

Solve the parentheses first

3 × 3 = 9.

Therefore,

(12 ÷ 4) × (18 ÷ 6) = 9
