Answer:
27/8
Step-by-step explanation:
first you would convert -.5 to -1/2 and add everything up by getting the same denominator
Answer:
3.375
Step-by-step explanation:First convert the 2 1/4 and the 1 5/8
then you just add it with the 0.5 or just use a calculator
2 1/4 = 9/4
1 5/8= 13/8
okay now do this ---> 0.5 + 9/4 +13/8 =3.375

The cost of cookies at store A are shown in the graph. The cost y for x cookies at store B is represented by the equation y=0.30x. Which of the following statements is true?
The relationship between the cost of cookies and the number of cookies is
a proportional relationship.
Correct response:
c. The cookies at store B cost moreMethod by which the above option is selectedThe function of the given graph for the cost of cookies at store A is found as follows;
The graph is a straight line passing through the origin, therefore, the equation is of the form;
y = m·x
The cost of 2 cookies = $0.5
Therefore;
The cost of 1 cookie at store A = $0.5 ÷ 2 = $0.25
Therefore, the cost of y cookies = 0.25·x
Where;
x = The number of cookies
The equation representing the cost y for x cookies in store B in dollars is given as follows;
y = 0.30·x
Therefore, the cost of 1 cookie at store B = $0.30 × 1 = $0.30
Therefore;
The cookies at store B cost moreLearn more about the proportional relationships here:

write the equation of the line, in standard form, that is perpendicular to y=3x-2 and passes through (-7,2)
Answer:
x+3y=-1
Step-by-step explanation:
y=3x-2 so m=3 old slope
the new slope must be -1/3 (opposite reciprocal of the old slope).
y-y0=m*(x-x0)
y-2=-1/3*(x-(-7))
y-2=-1/3x-1/3*7
y-2=-1/3x-7/3
3y-6=-x-7
The standard form for linear equations in two variables is Ax+By=C.
x+3y=6-7
x+3y=-1

The lengths of the two legs of a right triangle are 4 and 7. What is the length of the
hypotenuse? Express answer in Simplified Radical Form.
Answer:8.06
Step-by-step explanation:
4 x 4= 16 7 x 7 = 49
49+16=65
square root of 65 =8.06
Answer:
[tex] \sqrt{65} [/tex]
Step-by-step explanation:
To find the hypotenuese of a right angle you use the pythagreon theroem.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
a and b are the height and base, while c is the hypotenuese. simply insert the values in the equation and find the variable.
[tex] {4}^{2} + {7}^{2} = {c}^{2} \\ 16 + 49 = {c}^{2} \\ 65 = {c}^{2} \\ \sqrt{65} = c[/tex]
The radical form answer is above, otherwise it would be a decimal.
How do you get the equation of the line in fully simplified slope-intercept form?
Answer:
y= -2/5 x -4
Step-by-step explanation:
So the equation is y=mx+b. Where m=slope and b=y-intercept. To find b, you would see at what point does the line cross the y axis. That would be at -4 so, -4 would be the b or y-intercept. To find m, you would take two points on the line and use this equation:
m=(y2 - y1 )/(x2 - x1)
If you were using the points, (-10,0) and (0, -4) the equation would be:
m=(-4-0) / (0+10)
So, m= -2/5
The equation of the line would end up being:
y= -2/5 x -4

Trapezoid A B C D is shown. A diagonal is drawn from point B to point D. Sides B C and A D are parallel. Sides B A and C D are congruent. Angle C B D is 24 degrees and angle B A D is 116 degrees. What is the measure of angle ABD in trapezoid ABCD? 24° 40° 64° 92
Answer:
40 degrees
Step-by-step explanation:
The given trapezoid ABCD is shown in the figure, in which sides BC and AD are parallel.
Angle CBD=24 degrees.
Angle BAD=116 degrees.
As the diagonal BD cuts the two parallel sides BC and AD, so
Angle CBD = Angle ADB [alternate angles]
So, Angle ADB= 24 degrees.
Now, in the triangle ABD, the sum of all the three angles,
Angle ABD + Angle ADB + Angle BAD =180 degrees.
Angle ABD + 24 degrees + 116 degrees =180 degrees
So, Angle ABD= 180 - 24 - 116= 40 degrees.
Hence, Angle ABD = 40 degrees.
Answer:
40
