7th grades math help me pleaseeee
Answer:
7 attendees
Step-by-step explanation:
From the above question, we know that:
$10 = 5 attendees
$14 = x
Cross Multiply
$10 × x attendees = $14 × 5 attendees
x attendees = $14 × 5 attendees/$10
x attendees = 7 attendees
Therefore, if the budget for the cooperate team building is $14, the number of attendees is 7
A sphere has a radius of 12 inches. A second sphere has a radius of 9 inches. What is the difference of the volumes of the spheres?
The volume of the larger sphere is π
cubic inches greater than the volume of the smaller sphere.
Answer:
Solution given;
for sphere
radius [r]:12inches
another
radius [R]:9inches
Now
difference in volume of sphere:
volume of sphere of having radius [r-R]
=[tex] \frac{4}{3} πr³[/tex]-[tex] \frac{4}{3} πR³[/tex]
=[tex] \frac{4}{3} π[/tex](12³-9³)
= 1332π cubic inches
The volume of the larger sphere is ___1332__π cubic inches greater than the volume of the smaller sphere.
What is the equation in slope-intercept form
of the line that passes through the points
(-3, 10) and (3, 14)?
Answer:
C) y=2/3x+12
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(14-10)/(3-(-3))
m=4/(3+3)
m=4/6
simplify
m=2/3
y-y1=m(x-x1)
y-10=2/3(x-(-3))
y-10=2/3(x+3)
y=2/3x+6/3+10
y=2/3x+2+10
y=2/3x+12

"-3x" + 5 < "-10" Inequality 2: 7x + x - 4 > 28 Which of the following values makes BOTH inequalities TRUE? Select all that apply! 12 "-5" −152 "-8.25" 23 48 325
Answer:
12, 23, 48, 325
Step-by-step explanation:
So, when given two inequalities and asked to find the values that make both true, it is considered a system of equations. To solve a system of equation, you have to graph the inequalities and find where they intersect.
Inequality 1:
(-3x) + 5 < (-10)
Inequality 2:
7x + x - 4 > 28
simplifies to: 8x - 4 > 28
When graphed, the inequalities don't intersect, but rather have a similar shaded area overlapping from the point of 5 and greater.
Answers that apply from given list would be:
12, 23, 48, 325
If you try to solve a linear system by the substitution method and get the result 0 = 8, what does this mean? The system has
an infinito number colution
A the system has an infinite number of solutions
B The system has no solutions
C the system has one solution, (8,0)
D The system has one solution (0,8)
Answer:
The system has no solution because if 0=8, this means this is an empty set. If you get 2 numbers that don't equal each other for an answer then you know there's no solution

Answer:
16.97 or approx 17
Step-by-step explanation:
[tex]\sqrt{24}[/tex] = [tex]\sqrt{4}[/tex][tex]\sqrt{6}[/tex] = 2[tex]\sqrt{6}[/tex]
[tex]\sqrt{12}[/tex] = [tex]\sqrt{4}[/tex][tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex]
2[tex]\sqrt{6}[/tex] · 2[tex]\sqrt{3}[/tex] = 4[tex]\sqrt{18}[/tex] = 4[tex]\sqrt{9}[/tex][tex]\sqrt{2}[/tex] = 4·3[tex]\sqrt{2}[/tex] = 12[tex]\sqrt{2}[/tex] which is 16.97 or approx 17
Answer:
16.97
Step-by-step explanation:
The answer of this simplify if 16.97

Write in slope-intercept form an equation of the line that passes through the given points. (-16,8), (-4,5)
Answer:
y=-1/4x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-8)/(-4-(-16))
m=-3/(-4+16)
m=-3/12
m=-1/4
y-y1=m(x-x1)
y-8=-1/4(x-(-16))
y-8=-1/4(x+16)
y-8=-1/4x-16/4
y-8=-1/4x-4
y=-1/4x-4+8
y=-1/4x+4

Miss Dodson is wrapping a gift that is in a rectangular shoe box. The box is 12 inches long, 4 inches tall and 8 inches wide. How much wrapping paper will she need to cover the box if she doesn't plan to overlap any of the paper? Your answer would be labeled as inches squared or square inches.
Answer:
352 inches squared
Step-by-step explanation:
the amount of wrapping paper needed can be determined by calculating the total surface area
total surface area = 2lw+2lh+2hw
2(12x 8) + (2 x 12 x 4) + (2 x 4 x 8) = 192+ 96 + 64

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 8,17,26 fine the 31 term
Answer:
278
Step-by-step explanation:
Given
[tex]Sequence:= 8, 17, 26[/tex]
Required
The 31st term
The given sequence is an arithmetic sequence because
[tex]d = 17 -8= 26 -17 =9[/tex]
The 31st term, is then calculated as:
[tex]T_n = a + (n - 1)d[/tex]
Where
[tex]a = 8[/tex] --- The first term
[tex]T_{31} = 8 + (31 - 1)*9[/tex]
[tex]T_{31} = 8 + 30*9[/tex]
[tex]T_{31} = 8 + 270[/tex]
[tex]T_{31} = 278[/tex]
