Answer:
5 (12+3)
75
Step-by-step explanation:
so you multiply 5 with the inside of paranthesis. So 5 x 12 and 5 x 3
So its 60 + 15 which is 75. Hope this helps!

If M(2,3) is reflected in the line y=4, then M' is (6,3)
TRUE OR FALSE???
Answer:
It is false
Step-by-step explanation:
It's false since M' should be (2,5)

If using the method of completing the square to solve the quadratic equation x2 + 15x + 4 = 0, which number would have to be added to "complete the square"?
Answer:
The number which number would have to be added to "complete the square" is [tex]\mathbf{(\frac{15}{2})^2 }[/tex]
Step-by-step explanation:
We need to solve the equation [tex]x^2 + 15x + 4 = 0[/tex] by completing square method.
The general form is [tex]x^2+2(x)(y)+y^2=(x+y)^2[/tex]
Solving equation using completing square method
[tex]x^2 + 15x + 4 = 0[/tex]
We would be adding and subtracting 15/2 to make it a complete square
[tex]x^2+2(1)(\frac{15}{2} )+(\frac{15}{2})^2+4-(\frac{15}{2})^2=0[/tex]
So, now it can be written in form of [tex](x+y)^2[/tex]
[tex](x+\frac{15}{2})^2+4-\frac{225}{4}=0\\(x+\frac{15}{2})^2+4-\frac{225}{4}=0\\(x+\frac{15}{2})^2+\frac{4*4-225}{4}=0\\(x+\frac{15}{2})^2+\frac{16-225}{4}=0\\(x+\frac{15}{2})^2+\frac{-209}{4}=0\\(x+\frac{15}{2})^2-\frac{209}{4}=0[/tex]
So,using the method of completing the square to solve the quadratic equation x2 + 15x + 4 = 0 we get [tex]\mathbf{(x+\frac{15}{2})^2-\frac{209}{4}=0}[/tex]
The number which number would have to be added to "complete the square" is [tex]\mathbf{(\frac{15}{2})^2 }[/tex]

Angles A and B are supplementary angles. The mZA = (9x - 12) and the mZB = (24x + 60).
Answer:
/ A = 24°
/ B = 156°
Step-by-step explanation:
Supplementary angles add up to 180°.
_________________________________
Therefore, / A + / B = 180
(9x - 12) + (24x + 60) = 180
9x - 12 + 24x + 60 = 180
33x + 48 = 180
33x = 180 - 48
33x = 132
x = 132/33
x = 12/3
x = 4
_________________________________
/ A = (9x - 12)
= (9(4) - 12)
= (36 - 12)
= 24°
/ B = (24x + 60)
= (24(4) + 60)
= (96 + 60)
= 156°

Gloria’s washing machine is broken. Since her machine is pretty old, she doesn’t want to spend more than $100 for repairs. A service call will cost $35 and the labor will be an additional $20 per hour. There are no other charges. What is the maximum number of hours that the repair person can work without the total cost exceeding $100?
Answer:
The actual answer is 3.25
Step-by-step explanation:
I just took the test
the maximum number of hours that the repair person can work is 3.5 hours
Given :
Gloria doesn’t want to spend more than $100.
A service call will cost $35 and the labor will be an additional $20 per hour
Let 'h' be the maximum number of hours the repair can take.
Lets find out the total cost for 'h' hours
35+ additional 20 per hour
[tex]35+20h[/tex]
The total cost should not exceed 100
[tex]35+20h \leq 100\\20h \leq 100-35\\20h\leq 65\\Divide \; by \; 20\\h\leq 3.5[/tex]
So , the maximum number of hours that the repair person can work is 3.5 hours

At a desert resort, the temperature at 7 a.m. was 3°C. The temperature increased by an average of 3.4°C each hour until it reached 30.2°C. How long did it take to reach this temperature?
Answer: It will take 8 hours to reach this temperature.
Step-by-step explanation:
Given: At a desert resort, the temperature at 7 a.m. was 3°C.
The temperature increased by an average of 3.4°C each hour until it reached 30.2°C.
Let x be the number of hours taken to reach 30.2°C..
As per given ,
Initial temperature +(average increase in temperature) (Number of hours) = 30.2
⇒3+3.4x=30.2
⇒3.4x=30.2-3
⇒3.4x=27.2
⇒ x=8 [Divide both sides by 3.4]
Hence, it will take 8 hours to reach this temperature.

Boadu and Ansah formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively. If at the end of the year. Ansah received Gh€ 5.000.00 more than boadu how much was boadu shared?
Answer:
Step-by-step explanation:
The share of Boadu is Gh€ 222,222.22 if Boadu and Ansah formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
Boadu and Ansah formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively.
Let 4x be the share of Boadu and 5x be the share of Ansah
4x + 5x = 5,000,00
9x = 5,000,00
x = 55555.55
The share of Boadu = 4x = 4(55555.55) = 222,222.22
Thus, the share of Boadu is Gh€ 222,222.22 if Boadu and Ansah formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively.

Three friends each have some ribbon. Carol has 42 inches of ribbon, Tino has 2.5 feet of ribbon, and Baxter has 1.5 yards of ribbon. Who has the most ribbon? How do you know?
Answer: Baxter
Step-by-step explanation:
To solve this question, we need to know that:
12 inches = 1 foot
36 inches = 1 yard
The number of ribbon for each person will be:
Carol = 42 ribbons
Tino = 2.5 feet = 2.5 × 12 = 30 ribbons
Baxter = 1.5 yard = 1.5 × 36 = 54 ribbons
Therefore, Baxter has the most ribbon

The Perimeter of a Rectangle
Given a rectangle of dimensions W and L, the perimeter of the rectangle is:
P = 2W + 2L
Or, equivalently:
P = 2(W + L)
The dimensions of the icon for the mobile app are 1.5 cm and 3 cm, thus:
P = 2(1.5 cm + 3 cm)
P = 2(4.5 cm)
P = 9 cm

Step-by-step explanation:
If 3a - 2 = 10, what is the value of 8a + 1?
Answer:
8a+1=33
Step-by-step explanation:
you can solve 3a-2=10 by simplifying to 3a=12, so a=4. Then you replace the a in 8a+1 with 4 to get 32+1, which is 33
Answer:
33
Step-by-step explanation:
3a-2= 10
3a=12
a=4
in this equation a=4 so you substitute that value into the other equation
8(4) +1=33
Selina walked 2 1/2 miles in 2/3 hour. Dennis 6 3/4 miles in 1 1/2 hours. Who walked faster and how much faster?
Answer:
Dennis walked faster by 0.75 miles/hr
Step-by-step explanation:
a)Selina's speed
speed= distance
time
= 2.5 miles = 3.75 miles/hr = the slower
2/3 hrs
b) Dennis' speed
speed = distance
time
= 6.75 miles = 4.5 miles/hr = the faster
1.5 hrs
difference in speed:
faster - slower
4.5 - 3.75
=0.75 miles/hr
Dennis walked 0.75 miles per hour faster than Selina's speed.
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
To determine Selina's speed
speed = distance/time
speed = 2.5 miles/(2/3) hour
speed = 3.75 miles/hour
To determine Dennis' speed
speed = distance/time
speed = 6.75 miles/(1.5) hour
speed = 4.5 miles/hour
Here Dennis' speed is greater than Selina's speed which means Dennis walked faster.
So the difference in speed = Dennis' speed - Selina's speed
The difference in speed = 4.5 miles/hour - 3.75 miles/hour
The difference in speed = 0.75 miles/hr
Thus, Dennis walked 0.75 miles per hour faster than Selina's speed.

Lily plans to paint a stencil design on the wall in her room the stencils has one part yellow 3 Part Blue and 4 parts are blue and 4 parts are white .The area of the the walls that she must paint is 480 square feet a quart of paint approximately covers 80 square feet .what is the minimum amount of paint that Lily needs to buy
Answer and explanation:
Since a quarter(1/4) of paint covers 80 square feet, a whole paint would cover 80×4= 320 square feet of the wall
Remaining part of the wall left unpainted after using one whole paint
480-320= 160 square feet
Therefore paint required for remaining unpainted part
= 160/80= 2 quarters of paint(1/4+1/4)= 1/2 paint
Total paint required for the wall = one whole paint + half paint = 1+1/2= 1 1/2
Total paint required is one and half
Or
We divide area of wall by area of wall covered by each quarter
480/80=6 quarters of paint
6 quarters of paint = 1/4+1/4+1/4+1/4+1/4+1/4
We still get same answer
= 1 1/2
Answer: A 1 quart yellow, 2 quarts blue, 3 quarts white
Step-by-step explanation:
if u divide 480 by 80 you will get 6 so u will only need 6 quarts of paint.
can someone help me please. thanks!
