Answer:
£828
Step-by-step explanation:
The first step to solve this problem is to find the surface area of the solid box. The formula for surface area for a rectangular prism is [tex]2(wl+hl+hw)[/tex]where w is width, l is length, and h is height. Plugging values in gives [tex]2(90*90+70*90+70*90)=41400[/tex] cm^2.
Because each cm^2 of paint costs £0.02, a ratio can be created.
[tex]\frac{1}{0.02} =\frac{41400}{x}[/tex]
Cross multiplying gives: [tex]x=828[/tex], so to paint the whole outside of the box, it would cost £828.

One angle of a rhombus measures 110, and the shorter diagonal is 4 inches long. How long is the side of the rhombus?
side of rhombus: 2.44 inch
Use the sine rule:
[tex]\sf \dfrac{sin(A)}{a} = \dfrac{sin(B)}{b}[/tex]
============= Let the side be "b"
[tex]\rightarrow \sf \dfrac{sin(110)}{4} = \dfrac{sin(35)}{b}[/tex]
[tex]\rightarrow \sf b = \dfrac{sin(35)*4}{sin(110)}[/tex]
[tex]\rightarrow \sf b = 2.441549178[/tex]
[tex]\rightarrow \sf b =2.44 \ in[/tex]
Answer:
3.5 in (nearest tenth)
Step-by-step explanation:
Properties of a rhombus:
Quadrilateral (four sides & four interior angles)Parallelogram (opposite sides are parallel)All sides are equal in lengthOpposite angles are equal in measureDiagonals bisect each other at right anglesInterior angles sum to 360°Adjacent angles are supplementary (sum to 180°)Diagonals bisect interior anglesTherefore, a rhombus is made up of 4 congruent right triangles.
** see attached diagram **
To find the side length of the rhombus, we need to calculate the hypotenuse of the right triangle.
As the shorter diagonal is 4 in, the base of the right triangle is 2 in
The angles that measure 110° are the angles by the shorter diagonal. Therefore, the base angle of the right triangle is 55°
Using cos trig ratio:
[tex]\sf \cos(\theta)=\dfrac{A}{H}[/tex]
where:
[tex]\theta[/tex] is the angleA is the side adjacent the angleH is the hypotenuseGiven:
[tex]\theta[/tex] = 55°A = 2H = x[tex]\implies \sf \cos(55^{\circ})=\dfrac{2}{x}[/tex]
[tex]\implies \sf x=\dfrac{2}{\cos(55^{\circ})}[/tex]
[tex]\implies \sf x=3.486893591...[/tex]
Therefore, the side of the rhombus is 3.5 in (nearest tenth)

solve x/9 + 1/3 = -4/3
The solution is x = ?
Answer:
x = - 15
Step-by-step explanation:
[tex]\frac{x}{9}[/tex] + [tex]\frac{1}{3}[/tex] = - [tex]\frac{4}{3}[/tex] ( multiply through by 9 to clear the fractions )
x + 3 = - 12 ( subtract 3 from both sides )
x = - 15
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=−15

Identify the equation for the parabola with the focus F(0,-9.5) and directrix y =9.5
Considering the given focus and directrix, the equation of the parabola is given by:
[tex]y = -2.375x^2[/tex]
What is the equation of a parabola?The equation of a parabola, with a directrix in y, is:
[tex]y - k = a(x - h)^2[/tex]
In which:
The value of a is of 0.25C.The vertex is (h,k).The focus if (h, k+C).The directrix if y = k - C.In this problem, we have that the x-coordinate of the vertex is h = 0.
From the focus and the directrix, we have that:
k+C = -9.5
k - c = 9.5.
Hence k = 0, C = -9.5 = a = 0.25C = -2.375.
Thus the equation of the parabola is given by:
[tex]y = -2.375x^2[/tex]

Gus bought 12 gallons of gas at $2.17
a gallon, a bottle of oil for $2.49 and
two jugs of anti-freeze for $7.98 each.
He paid $1.52 in tax for the oil and
anti-freeze. If he paid with a $50 bill,
how much change did he receive?
bro help lol
Answer:
$3.99
Step-by-step explanation:
a gallon of gas=2.17$
12 gallons of gas=2.17$×12 =26.04$
2 jugs of anti freeze =7.98$ × 2 = 15.96$
a bottle of oil = 2.49$
tax= 1.52$
total= 46.01$
he paid 50$
so the change could be 50$-46.01$ = 3.99$
the answer is 3.99$

Find the slope and the equation for the line passing through the points: (-3,0) and (-1,2)
Answer:
slope: 1equation: y = x +3Step-by-step explanation:
The slope of the line between two points can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (2 -0)/(-1 -(-3)) = 2/2
m = 1 . . . . . the slope of the line is 1
__
The value of the y-intercept can be found by solving the slope-intercept equation for b.
y = mx +b
b = y -mx
b = (0) -(1)(-3) = 3 . . . . . using point (x, y) = (-3, 0)
The equation of the line with slope 1 and y-intercept 3 can be written as ...
y = x +3

18x - 7y = -17
3x - 3y = -12
Enter the correct answer.
Answer:
-> (x,y) => (1,5)
x = 1y = 5Step-by-step explanation:
Let's solve your system by elimination.
18x−7y=−17;3x−3y=−12
Multiply the second equation by -6, then add the equations together.
(18x−7y=−17)
−6(3x−3y=−12)
Becomes:
18x−7y=−17
−18x+18y=72
Add these equations to eliminate x:
11y=55
Then solve 11y=55for y:
11y=55
11y/11 = 55/11
(Divide both sides by 11)
y=5
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
18x−7y=−17
Substitute5foryin18x−7y=−17:
18x−(7)(5)=−17
18x−35=−17(Simplify both sides of the equation)
18x−35+35=−17+35(Add 35 to both sides)
18x=18
18x/18 = 18/18
(Divide both sides by 18)
x=1
give the missing angle
Answer:
60°, 115°, 65°Step-by-step explanation:
Angles a and 60°, also c and 65° are alternate interior angles and therefore are equal:
a = 60°c = 65°Angles b and 65° form a linear pair, so they sum to 180°
b + 65° = 180°b = 180° - 65°b = 115°Answer:
a = 60°
b = 115°
c = 65°
Step-by-step explanation:
Alternate Interior Angles Theorem
If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent (same).
Therefore, a = 60° and c = 65°
Angles on a straight line sum to 180°
⇒ b + 65° = 180°
Subtracting 65° from both sides:
⇒ b + 65° - 65° = 180° - 65°
⇒ b = 115°

Cooper gave out a survey to some students in his school about their favorite color.
tudents could choose between red and blue. 129 of those surveyed said their favorite
color was red. 57% of the students surveyed said their favorite color was blue. How
many students were surveyed in total?
Answer:
300 students were surveyed.
Step-by-step explanation:
Well, we know that 57% of students like blue, so that leaves 43% who like red. By simply dividing 129 by 43, we get 3, so know we can conclude that 1% is equal to 3 students. Knowing this, we can multiply 3 by 57 to get 171. Adding these up, we get 300, and we can verify this, by simply finding the difference between 57 and 43, which is 14. Now that we also know that 1% is equal to 3 students, we can multiply 14 by 3, to get 42, which is also the difference between 171 and 129.
