Answer:
-23
Step-by-step explanation:
Given 4v-3
evaluate when v = -5
So basically we want to find the value of the expression when the variable (v) equals -5
so
* plug in -5 for v*
4(-5)-3
4*-5=-20
-20-3=-23
So we can conclude that when v = -5 the value of the expression is -23
Answer:
4v-3 = -23Explanation:
given the expression: 4v-3
if v = -5
4v-3 (let's subsitute v)
4v-3 = 4×(-5)-3
4v-3 = -20 - 3
4v-3 = -23

Find the distance between (-22,15) and (30, -25).
Answer:
65.60
Step-by-step explanation:
Formula :
Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2
Solution :
Distance between two points = √(30−−22)2+(−25−15)2(30--22)2+(-25-15)2
= √522+(−40)2522+(-40)2
= √2704+16002704+1600
= √43044304 = 65.6049
There are already 1,200 gallons of water in a swimming pool. If water is filling the pool at a rate of 30 gallons per minute, which expression indicates the amount of water, in gallons, in the swimming pool after m minutes?
Answer:
n = 30m + 1,200
Step-by-step explanation:
let n = gallons
m = minutes
There are 30 gallons per minute, so 30 is multiplied by the minutes, and because there are already 1,200 gallons of water, you add 1,200
Carmen leaned a 13-foot ladder against a wall. If the base of the ladder is 4 feet from
the bottom of the wall, approximately how far up the wall does the ladder reach?
Answer:
13+4=17
Step-by-step explanation:
The required ladder reaches approximately 12.37 feet up the wall.
What is the Pythagorean theorem?The Pythagorean theorem is a fundamental theorem in geometry that describes the relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In algebraic terms, the Pythagorean theorem can be written as:
a² + b² = c²
where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.
Here,
We can use the Pythagorean theorem to solve this problem. Let's denote the distance from the bottom of the wall to where the ladder reaches the wall as h. Then we have,
h² + 4² = 13²
h² + 16 = 169
h² = 153
h ≈ 12.37
Therefore, the ladder reaches approximately 12.37 feet up the wall.

The front of the home is being painted, not including the door the door measures 9ft by 2ft how many square feet will be needed
IGNORE THE WRITING
Answer:
ANSWER BELOW
Step-by-step explanation:
If the door is 9 x 2 ft (18 sq ft):
12 x 18 = 216 sq ft. (Front face including the door)
216 sq ft - 18 sq ft = 198 (Front face not including the roof or door)
For the roof, the formula is h b/2:
So if the height is 4 and the base is 18, the area of the roof is 36.
To find the total area, you must add the area of the front face and the roof (without the door).
198 + 36 = 234 sq ft

Given the area of a trapezoid is 86 in’, and the height is 4 in. If one base is 18 in, determine the other base.
Answer:
25 = base
Step-by-step explanation:
I searched all of this on YT to try and help
so first we need to know the area of a Trapezoid
A = 1/2h(b + b)
86 = 1/2(18 + b)4
we dont know the base where going to put b
we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.
172 = (18 + b)4
the 4 is multipling so divide it on both ends.
43 = (18 + b)
then do the opposite operation on the 18, by subtracting 18 on both sides.
25 = b
is the base
check the work by plugging it back in
A = 1/2h(b + b)
A = 1/2 4(18+25)
A = 1/2 4(43)
A = 1/2(172)
A = 86in

given y²+5y-6= (y+p) (y+q), find the values of p and q.
Answer:
(y+6)(y-1)
Step-by-step explanation:
literally factorising.
y^2 x -6 = -6y^2
u need two numbers that multiply to make -6 and add them together to make +5 which is +6 and -1.
Answer:
p = 6, q = - 1 , or p = - 1, q = 6
Step-by-step explanation:
Factorise the quadratic expression on the left side
y² + 5y - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the y- term (+ 5)
The factors are + 6 and - 1 , since
6 × - 1 = - 6 and 6 - 1 = + 5 , then
y² + 5y - 6
= (y + 6)(y - 1) = (y - 1)(y + 6)
Compare to (y + p)(y + q) , then
p = 6, q = - 1 or p = - 1, q = 6

A. the $5 off coupon
B. the 10% off coupon
C. either one
D. cannot be determined
Answer:
A. the $5 off coupon

10% off would only be 2.99 off the bill making it 26.91 but the $5 would take off more
The coupon I would use to save the most amount of money on the total bill is my friend's coupon worth $5.
Which coupon should I use?Coupons reduce the price of an item. An item becomes cheaper after a coupon has been used. In order to determine the better coupon, calculate the price after each coupon has been used.
Coupon 1 : 10% x 29.9 = $3
Coupon 2 : 29.90 - $5 = $24.90

4 bags will be required.
Step-by-step explanation:
Patio is in the shape of a parallelogram.
Formula for the area of a parallelogram is,
Area = [tex](\text{Base})(\text{Height})[/tex]
= 16.2 × 12
= 194.4 square feet
∵ 50 square feet area is covered by 1 bag of concrete mix.
∴ 1 square feet area will be covered by [tex]\frac{1}{50}[/tex] bag of concrete mix
∴ 194.4 square feet patio will require the concrete mix = [tex]\frac{194.4}{50}[/tex]
= 3.888
≈ 4 bags
Therefore, 4 bags of concrete mix will be required by Dave to add a new patio.
John travels 16m ^2 +100 miles. /since he can only travel 8m +10 mph, it takes him 2m hours to make the trip. Solve for m
Answer:
m = 5
Step-by-step explanation:
distance traveled D= 16m^2+100 miles
speed, S= 8m+10 mph
time taken, T = 2m hours
We know that D = S×T
⇒ 16m^2+100 = (8m+10)× 2m
⇒ 16m^2+100 = 16m^2+ 20m
⇒ 20m = 100
⇒ m = 5
Therefore, the value of m is 5

A batch of 24 cupcakes requires 9 ounces of flower. Julio made 132 cupcakes for the bake sale. How many pounds and ounces of flower did he use?
Answer:
49.5 ounces the flower
3 pounds, 1.5 ounces
Step-by-step explanation:
Given that :
24 cupcakes 9 ounces of flower
Number of ounces of flower required for 132 cupcakes will be x
Using cross multiplication method :
24 cupcakes = 9 ounces
132 cupcakes = x ounces
Cross multiply :
24 * x = 132 * 9
24x = 1188
divide both sides by 24 to isolate x
x = 49.5
Hence, 49.5 ounces the flower is required for 132 cupcakes
To express in pounds :
1 pound = 16 ounces
49.5 ounces = 3 pounds 1.5 ounces

Cindy Lou deposited $85 in the bank earning 4.5% interest annually. About how many years will it take her to earn $11.48 in interest?
Answer:
3.00 years
Step-by-step explanation:
Cindy Lou deposited $85 in the bank earning 4.5% interest annually. About how many years will it take her to earn $11.48 in interest?
Your answer
Given data
Principal= $85
Rate= 4.5%
Intterest= $11.48
The simple interest formula is
SI= PRT/100
11.48= 85*4.5*T/100
cross multiply
11.48*100= 85*4.5*T
1148=382.5T
divide both sides by 382.5
T= 1148/382.5
T= 3.00 years
Hence the time is 3 years
