Answer:
90.
Step-by-step explanation:
Here 5 is one of the 4 prime factors, so dividing the lower (80) and upper limit (100) by 5 we have new lower limit 16 and new upper limit 20.
So the product of other 3 factors should be greater than 16 and less than 20. And we can have it from 18 only. Hence the number is 90.
The numbers between 80 and 100 having factor 5 are
80, 85, 90, 95, 100
16 = [tex]2^{4}[/tex]
17 = 17
18 = 2× 3 × 3
19 = 19
20 = [tex]2^{2}[/tex] × 5
90 = 2 × [tex]3^{2}[/tex] × 5

[tex] \frac{5}{7} \times 6[/tex]
what is 5/7 x 6
Answer:
[tex]\frac{30}{7}[/tex]
Step-by-step explanation:
to multiply a number by a fraction, just multiply straight across
you just do 5 * 6 to get 30 and since there isn't anything under the 6, you put an imaginary 1 to get you 7 so your answer will be 30/7

15.) In a week, Tara earns $15 less than three
times what Carrie earns. Tara earns $105.
How much does Carrie earn?
Answer:
Carries earns [tex]40[/tex] dollars

Kiran said that this diagram can show the solution to 16÷8=? or 16÷2=?, depending on how we think about the equations and the “?”.
EXPLAIN why he is correct.
Answer:
16÷2
Step-by-step explanation:
It would be 16 divided by 2. This is because in the diagram they are splitting 16 by 2. Splitting 16 by 2 gets you two 8's.

The volume of a cube related to the area of a face by the formula V =A^3/2. What is the volume of a cube whose face has an area of 25mm^2.
Answer:
Volume = 125 mm^3
Step-by-step explanation:
Here, we want to get the volume of the cube
What we have to do here is to substitute the value of the area
We have this as
:
V = 25^(3/2)
V = (√25)^3
V = 5 * 5 * 5 = 125 mm^3

Slope that is passing through (3,5) and (0,-7)
Answer: 4
Step-by-step explanation:
Slope: [tex]\frac{y_{2} -y_{1} }{x_{2}- x_{1} }[/tex]
y₂ = -7
y₁ = 5
x₂ = 0
x₁ = 3
[tex]\frac{-7 -5 }{0- 3 }=\frac{-12}{-3} = \frac{4}{1} = 4[/tex]

-3x + y= – 8
3x + 2y = – 13
X =?
y =?
Answer:
x=1/3
y=-7
Step-by-step explanation:
using the elimination method, you can add both equations vertically, to eliminate the x
-3x+y=-8
3x+2y=-13
3y=-21
y=-7
we then fix the value of y into the first equation
-3x+y=-8
-3x-7=-8
-3x=-8+7
-3x=-1
x=1/3
2x + 3y = 23

Problem 1
To find the y intercept, plug in x = 0 and simplify
f(x) = (x-2)(x+4)
f(0) = (0-2)(0+4)
f(0) = (-2)*(4)
f(0) = -8
We have x = 0 pair up with y = -8
The y intercept is (0,-8)
Answer: Choice D
========================================
Problem 2
(x-2)(x+4) is the same as x^2+2x-8 after using the FOIL rule. The distributive property is an alternate option.
The leading coefficient of x^2+2x-8 is 1. Since this leading coefficient is positive, it tells us that the parabola opens upward.
Answer: C) Parabola opens upward
========================================
Problem 3
Answers:
A = h(x)B = f(x)C = g(x)Explanation:
Note that 1-x^2 is the same as -x^2+1 and this has a negative leading coefficient. So the parabola opens downward. That must mean curve C matches with function g(x).
Both f(x) and h(x) have the same leading term of x^2. However, the constant terms are different. Because f(x) has a smaller constant (-4 is smaller than 4) this makes curve B to be f(x), while curve A is h(x). The larger the constant is, the further shifted up the curve will be.
51^7 -51^6 by 25
__*25
Answer:
Step-by-step:
51⁷-51⁶ = 51⁶(51-1) = 51⁶(50)
50 is divisible by 25, so 51⁷-51⁶ is divisible by 25.

Solve the equations
3a + b = 10 and 2a + 4b =0.
3a + b = 10
2a + 4b=0
Answer:
a = 4 , b = -2
Step-by-step explanation:
3a + b = 10
2a + 4b = 0
(By using elimination method, eliminate one variable) - to get only one equation
(3a + b = 10 ) 4
2a + 4b = 0
12a + 4b = 40
(minus)
2a + 4b = 0
10a = 40
a = 40/10
a = 4
(substitute a into an equation to get b)
2a + 4b = 0
2(4) + 4b = 0
4b = 0 - 8
b = -8/4
b = -2
